The sliding frame 5 is slidably connected to the sliding block 7, and the sliding block 7 is rotatably connected to the crank 8, and the crank 8 is rotatably connected to the mounting frame 3. After the crank 8 is rotated, the bottom end of the crank 8 moves in an arc, which can drive the sliding block 7 to move in an arc, and the sliding block 7 is slidably connected to the top of the sliding frame 5, so that the sliding block 7 can drive the sliding frame 5 to move upward or downward, so that the sliding frame 5 can control the position of the clamp 4 through the push-pull rods 6.

[0039] As a preferred solution of the present invention, the positioning mechanism includes: a positioning plate 9, a positioning frame 10, a spring 11, a fixing block 12 and an unlocking frame 13;

[0040] The positioning plate 9 is fixedly installed on the front side of the mounting frame 3, and the positioning frame 10 cooperates with the positioning plate 9. The positioning frame 10 is fixedly connected to the unlocking frame 13 and the spring 11 respectively, and the spring 11 is fixedly connected to the fixing block 12. The fixing block 12 is fixedly installed on the front side of the crank 8. After the positioning frame 10 is engaged with the positioning plate 9, the positioning frame 10 can connect the positioning plate 9 with the crank 8 to block the rotation of the crank 8 on the positioning plate 9, thereby realizing the positioning of the crank 8, so that the crank 8 can position the position of the sliding block 7 and the sliding frame 5, thereby realizing the positioning of the clamp 4, greatly increasing the stability of the clamp 4 during use.

[0041] As a preferred solution of the present invention, a plurality of positioning grooves arranged at equal intervals are provided at the bottom of the positioning plate 9, and a positioning block is fixedly installed on the top of the positioning frame 10. The top of the positioning block is detachably engaged with the inner wall of the positioning groove. After the positioning block is inserted into the inner side of the positioning groove, the positioning block can prevent the crank 8 from rotating, thereby realizing the positioning of the crank 8.

[0042] As a preferred solution of the present invention, symmetrically arranged rectangular through holes are opened on the top of the workbench 1, and the two clamps 4 are slidingly connected to the inner walls of the two rectangular through holes respectively.

First, the unlocking frame 13 is pulled on the top of the crank 8, so that the unlocking frame 13 drives the positioning frame 10 to disengage from the positioning plate 9, thereby unlocking the crank 8, and then the crank 8 is rotated. After the crank 8 is rotated, the bottom end of the crank 8 moves in an arc shape, which can drive the sliding block 7 to move in an arc shape, and the sliding block 7 is slidably connected to the top of the sliding frame 5, so that the sliding block 7 can drive the sliding frame 5 to move upward or downward, so that the sliding frame 5 can control the position of the clamp 4 through the push-pull rod 6. When the sliding frame 5 is pressed downward by the sliding block 7, the sliding frame 5 can pull the two push-pull rods 6, and the two push-pull rods 6 can pull the two clamps When the lever 4 is moved upward, the two push-pull rods 6 can be pushed, and the two push-pull rods 6 can push the two clamps 4 away from each other. After adjustment, the unlocking frame 13 is released so that the positioning frame 10 can automatically engage with the positioning plate 9. After the positioning frame 10 engages with the positioning plate 9, the positioning frame 10 can connect the positioning plate 9 with the crank 8 to block the crank 8 from rotating on the positioning plate 9, thereby realizing the positioning of the crank 8, so that the crank 8 can position the position of the sliding block 7 and the sliding frame 5, thereby realizing the positioning of the clamp 4, greatly increasing the stability of the clamp 4 during use, starting the electric push rod 2, the electric push rod 2 extends downward, pushing the mounting frame 3 to descend, and the mounting frame 3 drives the clamp 4 to fix the flange from top to bottom, so that the clamp 4 can adapt to flanges of various thicknesses, which is quick and convenient.
