The working principle is as follows: when using, at first will wait to process on the hardware is placed platform 35, if the diameter of waiting to process the hardware is greater than the diameter of platform 35, need break off with the fingers and thumb the separation blade 37 of platform 35 both sides earlier, again will wait to process the hardware and place on platform 35, place stable back, wave second handle 43 and drive axis of rotation 41 and rotate, axis of rotation 41 drives second bevel gear 40 and rotates, second bevel gear 40 drives first bevel gear 39 and rotates, thereby drive bracing piece 38 and rotate, because bracing piece 38 and lifter 34 are threaded connection, so when bracing piece 38 rotates, lifter 34 moves up and down along the screw thread of bracing piece 38 side, it stops to wave the second handle when waiting to process the ascending height in the vertical direction of hardware suitable.

Then, a first handle 5 is shaken, the first handle 5 drives a screw rod 4 to rotate, the screw rod 4 rotates to drive a fixing plate 6 to move towards the direction close to the hardware to be processed, and the shaking of the first handle 5 is stopped when a first buffer plate 8 is in contact with the hardware to be processed.

Then, a plane matching body 12 or an arc surface matching body 13 is selected according to the external shape of the hardware to be processed, if the plane matching body 12 is selected, the first stop block 14 is firstly clamped into the unsealed part of the through hole 10, then the first stop block 14 is rotated to be clamped into the groove 24, then the stop plate 25 is pulled out of the position of the fixed plane matching body 12, and at the moment, the length of the first connecting rod 15 is stretched to be in contact with the hardware to be processed. Then the first handle 5 is shaken to clamp the hardware to be processed against falling, the second handle 43 is rotated in the opposite direction to lower the platform 35, and then the first handle 5 is shaken to clamp the hardware to be processed by the first buffer plate 8 and the plane buffer plate 18.

In the clamping process, if the clamping is too tight, the positive electrode material 27 is in contact with the spring on the negative electrode material 28, and as the positive electrode material 27 and the negative electrode material 28 are connected with the battery 31 through the outgoing line 30, when the two springs are connected, the battery 31 is switched on, the signal emitter 32 emits a signal, and the signal receiver 33 positioned on the side surface of the workbench 2 receives the signal, so as to remind an operator to stop increasing the clamping force and immediately stop shaking the first handle 5.

If need change the hardware, at first lift platform 35 for original wait to process the hardware and place on platform 35, wave the first in command 5 and make the clamping-force reduce, then take away original wait to process the hardware, place new wait to process the hardware on platform 35, repeat above-mentioned clamping operation.

If need change into cambered surface cooperation body 13, repeat above-mentioned reduction clamping force process, then take back original position with baffle 25, then along two cooperation bodies of anticlockwise rotation, when cambered surface cooperation body 13 moved the intermediate position, repeat above-mentioned clamping process, at this moment, fix plane cooperation body 12 directly over cambered surface cooperation body 13.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
