The surface of the threaded rod 412 is threadedly connected to a threaded seat 413. Two positioning members 43 are slidingly provided on the top of the placement plate 41. The two positioning members 43 are mirror-imaged, and the opposite sides of the two positioning members 43 are respectively connected to the two threaded seats 413 through connecting rods 44.

[0027] When the workpiece needs to be positioned, first rotate the threaded rod 412, which in turn drives the threaded seat 413 to move, which in turn drives the connecting rod 44 to move, and then drives the positioning member 43 to move. Since the bearings of the two threaded rods 412 are connected to each other, when one of the threaded rods 412 is rotated, the other threaded rod 412 can be driven, and then rotating one threaded rod 412 can drive the two positioning members 43 to move toward each other, thereby achieving the positioning of the workpiece.

[0028] A clamping plate 433 is provided on the inner side of the positioning member 43 for sliding up and down. A movable column 431 is rotatably provided on the top of the positioning member 43. The bottom of the movable column 431 is threadedly connected to a screw rod 432. The bottom of the screw rod 432 is connected to the top of the clamping plate 433. A through hole is provided in the positioning member 43 to match the screw rod 432.

[0029] Rotate the movable column 431 to drive the screw rod 432 to move. Since the clamping plate 433 is slidably connected to the positioning member 43, and the clamping plate 433 is fixedly connected to the screw rod 432, the screw rod 432 is guided. At this time, when the movable column 431 rotates, it can drive the clamping plate 433 to move up and down.

[0030] A mounting seat 31 is fixedly provided on the top of the placement table 3, a connecting block 414 is fixedly provided on the bottom of the connecting seat 411, a connecting groove matching the connecting block 414 is provided on the top of the mounting seat 31, a plug-in block 311 is slidingly provided in the mounting seat 31, a plug-in groove matching the plug-in block 311 is provided on the front side of the connecting block 414, a slide rod 313 is fixedly provided on the front side of the plug-in block 311, the front side of the slide rod 313 extends to the front side of the mounting seat 31, the slide rod 313 is slidably connected to the mounting seat 31, a mounting block 312 is fixedly provided on the surface of the slide rod 313, and the mounting block 312 is connected to the mounting seat 31 through a reset spring.

[0031] Pull the slide bar 313 forward, thereby driving the plug-in block 311 to move forward, and then removing the plug-in block 311 from the plug-in slot. At this time, the limit on the connecting block 414 can be released, so that the placement plate 41 can be removed from the top of the placement table 3.

[0032] Mounting plates 42 are fixedly provided on the left and right sides of the bottom of the placement plate 41 . Hand wheels 421 are rotatably provided on the opposite sides of the two mounting plates 42 . The rotating shafts of the hand wheels 421 are connected to the rotating shaft of the threaded rod 412 .

[0033] An anti-skid pad is fixedly provided on the bottom of the clamping plate 433 , and the material of the anti-skid pad is rubber.

[0034] A knob 434 is fixedly provided on the outer side of the movable column 431 .

[0035] Working principle: When the workpiece needs to be positioned, first rotate the threaded rod 412, which in turn drives the threaded seat 413 to move, which in turn drives the connecting rod 44 to move, and then drives the positioning piece 43 to move. Since the bearings of the two threaded rods 412 are connected to each other, when one of the threaded rods 412 is rotated, the other threaded rod 412 can be driven, and then rotating one threaded rod 412 can drive the two positioning pieces 43 to move toward each other, thereby achieving the positioning of the workpiece.
