Shape is presented a theatrical performance as the last item on a programme.
In a kind of foregoing novel separated type micro grinder, chuck is fixedly installed on the grinding pestle below annular chuck
One, chuck two is fixedly installed on the connecting rod below annular chuck, chuck one cooperates to hold out against with chuck two realizes spring pressure
The control of contracting amount.
In a kind of foregoing novel separated type micro grinder, the top of the mill head is hollow-core construction, and bottom is
Solid sphere structure or conical structure.
By adopting the above-described technical solution, compared with prior art, by adopting the above-described technical solution, with existing skill
Art is compared, and the present invention improves the grinding efficiency of sample, reduces the contaminated possibility of laboratory sample, structure letter of the present invention
Single, easy to operate, selection is safe, with low cost.
Brief description of the drawings
Accompanying drawing 1 is the structural representation one of the present invention；
Accompanying drawing 2 is the structural representation two of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, but not as any limitation of the invention.
Embodiments of the invention：A kind of novel separated type micro grinder, as shown in drawings, including mill body 1 and grinds
Grinder first 2, length is 26cm after whole mill assembling, and the mill body 1 includes grinding pestle 3 and is enclosed on the middle part of grinding pestle 3
Shirk device 4, this shirks device 4 and moved up and down along grinding pestle 3, ring-type chuck 5 is fixedly installed at grinding pestle 3 middle part, connecting rod 6 is erected
Straight cutting enters in the ring-type chuck 5 and bottom of connecting rod 6 with shirking the upper along being connected of device 4, and the connecting rod 6 is adopted with shirking the connected mode of device 4
Link slot 11 is set used in the lower end of connecting rod 6, boss 1 is set and the boss 1 and link slot 11 along side on device 4 is shirked
Coordinate and realize and shirk being flexibly connected for device 4 and connecting rod 6, shirk button 7 in the setting of the top of connecting rod 6, spring 8 is enclosed on the top of connecting rod 6
And positioned at shirking between button 7 and annular chuck 5, the upper end of the spring 8 is held out against with shirking button 7, lower end and the annular of spring 8
Chuck 5 is held out against, and chuck 1 is fixedly installed on the grinding pestle 3 below annular chuck 5, on the connecting rod below annular chuck 5
