The first reinforcement 7 and the second reinforcement 8 are connected to the worktable 6 through a reinforcement mechanism.

[0027] Example 2:

[0028] like Figure 1-5 As shown, the reinforcement mechanism includes a connecting block 16 located within the workbench 6.

An inclined movable rod 21 is symmetrically and movably connected on one side of the connecting block 16 and above the half-gears 17. The top of the two sets of movable rods 21 is correspondingly connected to the two sets of connecting columns 20. The connecting column 20 is movably connected to the movable rod 21 and the connecting rod 19 via a pin.

[0029] Example 3:

[0030] like Figure 1-5 As shown, the workbench 6 has stroke holes 22 for the movement of two sets of connecting columns 20, and one end of one of the rotating shafts 18 is connected to the motor output end on the connecting block 16.

When the first reinforcement 7 and the second reinforcement 8 move in the same direction, they clamp and fix the hydraulic cylinder placed vertically on the top of the worktable 6. Then, the boring machine 12 is started to move down to perform internal boring operation on the hydraulic cylinder. This can provide good support for the entire hydraulic cylinder and fully ensure its stability during the boring process.
