Abstract
The utility model relates to self-tightening type insect breeding tweezers with adjustable clamping force. At present, live insects are often used in fields of entomology teaching and scientific research and experiments, young larvae, nymph or insects with smaller sizes are easy to be injured when clamped by common tweezers with long noses, in addition, the insects can die easily due to different holding force of different people, and eventually experiment results are inaccurate. The self-tightening tweezers comprise two tweezers arms and a 'V'-shaped spring plate, one end of the spring plate is mounted on one tweezers arm, and the spring plate is positioned between the two tweezers arms. The tweezers can provide constant clamping force, and the clamping force can be changed by means of adjusting the position of the spring plate and can be read via corresponding graduations on positioning screws on the tweezers arms, so that different clamping forces can be realized according to insects of different types or insects at different ages. The tweezers can reduce injury to the insects when the live insects are clamped, experiment efficiency and experiment accuracy are improved, and accordingly labor intensity is reduced.
Description
Technical field:
The utility model belongs to entomology teaching and insect scientific research field, and the self-tightening type that is specifically related to a kind of adjustable chucking power is supported the worm tweezers.
Technical background:
At present, in entomology teaching and scientific research and testing field, often use the live body insect, clamping live body insect because the tweezer head is that point is hard again, scratches insect usually with common sharp mouth tweezers easily; In addition, when operating different polypides, the chucking power of the grasp of different people difference and same people also be difficult to grasp identical chucking power, so when the operation polypide; The meeting damage that causes polypide in various degree; The particularly larva of low age, nymph, the perhaps less kind of polypide, the damage of polypide is even more serious; If when polypide damages tests such as then further carrying out drug effect, viability test, environmental impact factor mensuration again, will cause result of the test inaccurate.
Summary of the invention:
In order to solve common sharp mouth tweezers in the entomology teaching and scientific research during clamping insect, the vulnerable problem of polypide, the utility model provides a kind of self-tightening type of adjustable chucking power to support the worm tweezers.
This tweezers can be made up of along the spring leaf that the tweezer arm moves two tweezer arms and one, and wherein a tweezer arm has locating hole, and locating hole is narrow microscler, and another tweezer arm passes this locating hole, and two tweezer arms are intersected; Spring leaf is " V " font; One end is provided with a screwed hole, and screwed hole is with internal thread, and the screwed hole that dog screw passes locating hole and spring leaf is screwed; Spring leaf is installed in has on the tweezer arm of locating hole; And realize the location of spring leaf, the other end of spring leaf is supported on another tweezer arm, and spring leaf is positioned in the middle of two tweezer arms; Unclamp dog screw, can realize adjusting along locating hole move left and right spring leaf to chucking power; One side of locating hole is carved with the scale of representing chucking power, can read the size of chucking power through the corresponding scale value of dog screw.
This novel beneficial effect that brings is: can change the chucking power of tweezers through the position of regulating spring sheet, be reduced in the clamping live body insect process the injury of insect, improve the accuracy of test efficiency and test, thereby reduce labour intensity.
Description of drawings:
Fig. 1 is that the self-tightening type of this adjustable chucking power is supported worm tweezers overall structure front view.
Fig. 2 is the side view of the first tweezer arm and the second tweezer arm.
The specific embodiment:
Fig. 1 is that the self-tightening type of this adjustable chucking power is supported worm tweezers overall structure figure, and Fig. 2 is the side view of the first tweezer arm and the second tweezer arm.1 is the first tweezer arm among the figure, and 2 is the second tweezer arm, and two tweezer arms 1 and 2 all have a central axis hole 11; The central axis hole 11 that axis 3 passes two tweezer arms 1 and 2 is installed together two tweezer arms 1 and 2, and two tweezer arms 1 and 2 all can rotate freely around axis 3, two tweezer arms 1 and 2 bending intersections later in opposite directions; In crossover sites; Having hole, a control position 4, the second tweezer arms 2 on the first tweezer arm 1 passes these control position hole 4, two tweezer arms 1 and 2 and forms cross-like here; On the first tweezer arm 1, also have a narrow microscler locating hole 5; There is the spring leaf 6 of one " V " font to be installed in the middle of two tweezer arms 1 and 2; One end of spring leaf 6 is provided with a screwed hole 8; Dog screw 7 passes locating hole 5 by the tweezers outside and is tightened on the screwed hole 8 on the spring leaf 6, realizes the installation of spring leaf 6, and the other end of spring leaf 6 relies on tension force to be supported on the tweezer arm 2; Unclamping dog screw 7 can move left and right spring leaf 6; Locating hole 5 one sides are carved with the scale 9 of representing chucking power; The clamping head 10 of two tweezer arms is made into discoid.
Claims (3)
1. the self-tightening type of an adjustable chucking power is supported the worm tweezers, it is characterized in that this tweezers are made up of two tweezer arms and " V " font spring leaf, and an end of spring leaf is installed on the tweezer arm, and spring leaf is positioned in the middle of two tweezer arms.
2. support the worm tweezers according to the self-tightening type of the described this adjustable chucking power of claim 1, it is characterized in that the tweezer arm that spring leaf wherein is installed has a locating hole.
