In the process of rotating the worm rod 4, the turbine 2 and the mounting plate 6 are driven to rotate under the meshing action, so that the angle of the clamped workpiece can be adjusted, and the adjustment accuracy is high, and the turbine 2 and the worm rod 4 have self-locking ability and high stability. A crank 5 is fixedly installed on one end of the worm rod 4, and a mounting plate 6 is fixedly installed on the top of the turbine 2.

The radius of the positioning rod 7 is consistent with that of the slot 13, and a clamping plate A8 is fixedly installed on the top of the positioning rod 7. The clamping plate A8 and the clamping plate B11 The shapes are all L-shaped. The L-shaped clamping plate A8 and clamping plate B11 can effectively improve the contact surface with the workpiece during the process of clamping the workpiece, and can limit the workpiece to a certain extent, and have strong applicability. A fixing plate 9 is fixedly installed on the top of the mounting plate 6, and a thread is provided on the inner side of the fixing plate 9. The thread provided on the inner side of the fixing plate 9 is meshed with the thread on the surface of the threaded rod 10. The setting of the thread on the inner side of the fixing plate 9 can drive the clamping plate B11 to slide along the mounting plate 6 under the action of the thread during the rotation of the threaded rod 10, so that the clamping effect of the workpiece can be achieved in cooperation with the clamping plate A8. The inner side of the fixing plate 9 is threadedly connected to the threaded rod 10, and one end of the threaded rod 10 is rotatably connected to the clamping plate B11. The clamping plate B11 is slidably connected to the mounting plate 6, and a turning handle 12 is fixedly installed on one end of the threaded rod 10.

The top end of the clamp A8 is rotatably connected to a limiting plate 17.

[0025] Working principle: When clamping a workpiece, first adjust the position of the clamping plate A8 according to the size of the workpiece. First, pull the clamping plate A8 and the positioning rod 7 out from the inside of the slot 13 from bottom to top, then adjust to a suitable position and align the positioning rod 7 with the adjacent slot 13 and insert it inside. Then, place the workpiece on the surface of the mounting plate 6 and rotate the threaded rod 10. Under the action of the thread, the clamping plate B11 will slide along the mounting plate 6, so that it can cooperate with the clamping plate A8 to clamp the workpiece. During the clamping process, the workpiece will first contact the pad 16, so that an effective protection effect can be obtained. During the process, if the workpiece needs to be rotated at an angle, the crank 5 can be held and the worm gear 4 can be turned. The turbine 2 will be driven to rotate under the meshing action, thereby driving the mounting plate 6 and the workpiece to rotate together, thereby effectively improving the processing efficiency. When the pad 16 needs to be replaced, first turn the limit plate 17 so that it no longer presses against the T-plate 15, then pull out the pad 16 and the T-plate 15 along the T-slot 14 and replace them. When installation is required, first align the T-plate 15 with the T-slot 14 and insert it, then turn the limit plate 17 and make it press against the surface of the T-plate 15 again, and the installation of the pad 16 is completed.
