Downward motive force, so as to be converted into the screw up or down of swing arm so that briquetting is drawn the end face of gear
Stretch compression or unclamp, wherein, pressuring action is stretched as predominant intermolecular forces using the end face to gear, and clamping jaw is to the folder of top circle
Clamp force functions only as the effect of centering as auxiliary, the combination of double acting work more than, realizes and the part of thin wall is pressed from both sides
Tightly, and part deformation will not be caused.
2nd, in the utility model, stop screw and threaded hole is set, the linear motion of push pedal can be caused, be changed into swing arm
Spiral or the motion that declines of spiral, be here easy to open or compresses gear, the structure setting is more ingenious, realize oneself
Dynamic that gear is fixed and clamped, dynamics is just.
The preferred scheme 1 that improvement to base case is obtained, the one end of swing arm away from briquetting is provided with screwed retaining ring, so may be used
To avoid swing arm from departing from push pedal, screwed retaining ring realizes auto lock effect.
The junction of the preferred scheme 2 that improvement to preferred scheme 1 is obtained, push pedal and swing arm is provided with bearing, reduces swing arm
In rotation process, the abrasion to push pedal.
The preferred scheme 3 that improvement to preferred scheme 2 is obtained, deformation block is caoutchouc elasticity block, is easy to the both sides to gear
It is clamped, and abrasion will not be produced to top circle.
