As shown in fig. 1, 2 and 3, a small bending machine includes a table 100, a clamp provided on the table 100, a driving bending wheel 410 and a driven bending wheel 420 provided on the table 100. The clamping piece comprises a fixed block 210 and a moving block 220, the fixed block 210 is fixedly connected with the surface of the workbench 100, the moving block 220 is connected with the surface of the workbench 100 in a sliding mode, and a clamping space for clamping the piece to be bent is formed between the fixed block 210 and the moving block 220. Through the position of adjustment movable block 220 to change the size in centre gripping space, make the holder can the not equidimension piece of bending of treating of centre gripping, thereby enlarge the application scope of bender.

Specifically, a sliding groove 230 is formed in the workbench 100, a screw rod 240 is fixedly arranged in the sliding groove 230, the screw rod 240 cannot rotate, and the sliding groove 230 is communicated with the upper surface of the workbench 100. The lower end of the moving block 220 is received in the sliding groove 230, and the lead screw 240 passes through the lower end of the moving block 220, but the lead screw 240 and the moving block 220 are not in threaded connection, so that the moving block 220 can move along the lead screw 240 under the driving of external force. The moving block 220 is provided with a containing cavity, a worm wheel 310 and a worm 320 which are meshed with each other are arranged in the containing cavity, the lead screw 240 penetrates through the worm wheel 310, the lead screw 240 and the worm wheel 310 are coaxially arranged, the lead screw 240 is in threaded connection with the worm wheel 310, and the worm wheel 310 is in contact with the side wall of the containing cavity, so that the worm wheel 310 can rotate relative to the side wall of the containing cavity, but can not displace on the side wall of the containing cavity. The upper end of the worm 320 passes through the upper surface of the moving block 220.

Through applying the revolving force to the upper end of worm 320, make worm 320 drive worm wheel 310 rotate, worm wheel 310 and lead screw 240 threaded connection, and lead screw 240 is fixed to be set up in the groove 230 that slides, so worm wheel 310 can slide along lead screw 240, worm wheel 310 contacts with the lateral wall of holding chamber, the worm wheel 310 that makes the removal drives movable block 220 and moves together, movable block 220 lower extreme is by the lateral wall centre gripping of the groove 230 that slides, make movable block 220 can not follow worm wheel 310 and take place the rotation, thereby adjust the size in centre gripping space. The worm wheel 310 and the worm 320 have a self-locking function, that is, only the worm 320 can drive the worm wheel 310 to rotate, but not the worm 310 can drive the worm 320 to rotate, so that the moving block 220 can only be driven to move from the worm 320, and the moving block 220 cannot be displaced due to overlarge stress in the bending process.

Specifically, the worm 320 is provided with a driving wheel 330 at the upper end penetrating through the moving block 220, and the driving wheel 330 is provided to facilitate applying an external force thereto. The driving wheel 330 is provided with an anti-slip pattern 340 along a circumferential side for increasing a frictional force.
