Abstract

A screw strip includes a strip body and a plurality of sleeves. Said strip body has a plurality of first punch holes that arrange axially with equal spaces therebetween, and a plurality of second punch holes that lie around the periphery of the first punch holes and communicate with said first punch holes. One end of each of said sleeves connects to said strip body at places corresponding to the periphery of the first punch holes. Said sleeves have some long holes through their inner walls and outer walls, and said long holes communicate with corresponding second punch holes. Some ribs and some grooves are formed on the inner walls of said sleeves. Said grooves lie at places corresponding to the long holes and communicate with corresponding long holes. When said sleeves are forced to expand outward, said grooves break up to said long holes, so the screws installed in said sleeves can pass through said sleeves.

Screw pin

Technical field

The present invention relates to a screw strap, and more particularly to a screw strap that allows the screw to be smoothly detached. Background technique 】

According to the existing screw belt, the main belt body is formed with a plurality of positioning holes arranged at equal intervals, and a ring sleeve is arranged on each of the positioning holes, and the side edges of the ring sleeves extend to the positioning holes. The holes are arranged equidistantly, such that when the screw is placed in the collar and the work nail to be locked is pushed by an external force, the screw is pressed against the outer sleeve. The inner wall surface of the ring sleeve causes the hole groove of the ring sleeve to be compressed by the ground and is broken to make the screw

When the hole of the screw belt formed on the belt body is broken as a ring sleeve, the hole groove is formed when the ring is pressed against the belt body, and the main nail is pressed against the ring. Inside (the aperture at the opening is small), so the screw must have been pushed by the external force for a period of time, the hole will be broken, so that the user will have a great burden on the operation for a long time. Disadvantages of poor operating comfort. Invented content

The belt body 10 is made of a flexible material and has a strip-shaped body 11 having a strip shape. The strip body 11 has a first surface 111 and a first side opposite to the first surface 111. Two sides 112, and the strip body 11 is formed with a plurality of first perforations 12 (shown in FIG. 4) which are arranged at equal intervals in the axial direction and penetrate through the first and second faces 111, 112 thereof. 11 is formed with a plurality of second perforations 13 (shown in FIGS. 4 and 5) respectively located at the periphery of the first perforations 12 and extending through the first and second faces 111, 112, and each of the second perforations 1 ₃ is in communication with the first perforation 12 in which it is located.

The collars 20 are respectively connected to the first surface 111 of the belt body 10 at one end thereof, and are located at the periphery of the first through holes 12, and each of the collars 20 is provided with a plurality of inner and outer portions. An elongated perforation 21 of the annular wall, and the elongated perforations 21 are penetrated through the second perforations 13 at the opposite positions, and a plurality of ribs 22 are disposed along the inner ring wall of each of the collars 20, and each of the ribs 22 is provided The ribs 22 are located between the two elongated perforations 21, and the inner ring walls of the collars 20 are provided with a plurality of grooves 23, and the grooves 23 are located at the corresponding elongated perforations 21, and The elongated perforations 21 and the free ends of the collars 20 are in communication with each other, and the cross-sections of the grooves 23 are V-shaped in cross section.

The above is a description of the construction of each of the screw belts 100 of a preferred embodiment of the present invention, and then its use and its features are as follows:

First, a plurality of screws 30 are respectively inserted into the collars 20 one by one, so that the body portion 31 of the screw 30 is exposed to the free end of the collar 20, and the head 32 of the screw 30 is located at the sleeve 32. The inside of the collar 20, and the head 32 of the screw 30 is received by the rib 22 on the inner wall surface of the collar 20. In this way, the screws 30 can be coupled to the screw strap 100 (as shown in Figure 7) for use by the user in conjunction with an automatic screwdriver screw feeder (not shown). Referring to FIG. 7 to FIG. 9, when the screw strap 100 is used with an electric screwdriver, the screwdriver 40 of the electric screwdriver abuts against the head end 321 of the screw 30 and applies force to the head of the screw 30. The portion 32 is displaced by the driver's head 40 and begins to displace toward the free end of the collar 20. At this time, since the rib 22 of the collar 20 abuts against the head 32, when the head 32 is toward the collar When the free end of 20 is displaced, the pressure on the rib 22 can be gradually increased to increase the tension of the outer ring 20, so that the collar 20 can be displaced extremely shortly at the head 32. The tension is reached to the limit of tension, and the tension of the collar 20 is concentrated into the groove 23, causing cracks to start from the groove 23 (as shown in Fig. 8), and the crack is continuously enlarged to The elongated perforation 21 is connected (as shown in Fig. 9), and the collar 20 can be smoothly torn completely so that the head 32 of the screw 30 can be smoothly passed from the free end of the collar 20. It is completely worn out and locked into the workpiece.

Therefore, since the screw belt 100 of the present invention is formed with a plurality of grooves 23 corresponding to the elongated perforations 21 on the inner wall surface of the collar 20, the collar 20 can be expanded by an external force. The groove 23 is split first, and in turn causes the crack of the groove 23 to communicate with the elongated perforation 21. In this way, the collar 20 can be gradually cracked when it is initially stressed and expanded, so as to offset the stress by gradually cracking, so that the collar 20 can be completely completed in a smoother manner. The crack is opened for the screw 30 to pass through, that is, when the screw 30 passes, the stress applied to the collar 20 is gradually offset by the crack, and there is no shock caused by excessive transient stress. In addition, since the present invention forms a plurality of ribs 22 on the inner wall surface of the collar 20, the collar 20 can be brought into contact with the screw 30 by the rib 22 to increase the stress of the expansion. The external expansion stress can be caused by the rupture of the groove 23 in a very short time (very short screw displacement stroke), that is, the rib 22 can abut against the screw 30, and the collar 20 is obtained. Before the screw 30 has not been displaced, a certain tension is accumulated to increase the speed at which the groove 23 is cracked, and the screw 30 is smoothly passed through the screw belt 100.
