The third clamping mechanism 4 includes a third fixed seat 41 for placing a connecting rod 13 and a third pressing claw 44 for pressing the support column 12 toward the third fixed seat 41. The workbench 1 is also provided with a mounting seat 8 for simultaneously positioning and supporting the main rod 11 and the support column 12.

[0024] It should be noted that: in this application, there are two main rods 11, a support column 12 and a connecting rod 13. Each main rod 11 is fixedly clamped by three groups of first clamping mechanisms 2, and the three groups of first clamping mechanisms 2 are distributed along the length direction of the main rod 11. In this application, there are two mounting seats 8, and the mounting seats 8 are located below the connection between the main rod 11 and the support column 12. The support column 12 is fixedly clamped by a group of second clamping mechanisms 3, and the second clamping mechanism 3 is located in the middle of the support column 12. In addition, the connecting rod 13 is fixedly clamped by a group of third clamping mechanisms 4, and the third clamping mechanism 4 is located in the middle of the connecting rod 13.

[0025] The first clamping mechanism 2 also includes a first driving member 21, on which a first driving rod 23 is provided. The first driving rod 23 moves back and forth in the height direction. The first pressing claw 24 is hinged to the upper end of the first driving member 21. The first driving member 21 is hinged with a first connecting rod 25 that is hingedly matched with the middle part of the first pressing claw 24. The first driving rod 23 moves back and forth in the height direction, thereby realizing the swing of the first pressing claw 24, thereby realizing the switching between the first pressing claw 24 and the main rod 11 between the abutment and disengagement states.

[0026] The second clamping mechanism 3 also includes a second driving member 32 and a connecting seat 35. The middle part of the second pressing claw 34 is hingedly matched with the connecting seat 35. A second driving rod 33 is provided on the second driving member 32.
