[0035] In addition, the thread of the threaded rod 206 is divided into two sections, and the two sections of the thread are in opposite directions, which facilitates the two movable blocks 207 to move relative to or away from each other at the same time. A rotating handle is fixed on the upper surface of the threaded rod 206 to facilitate the rotation of the threaded rod 206.

[0036] In addition, a slider is fixed on the side of the movable block 207 away from the static disk body 3, and two sliding grooves are provided on the side of the inner cavity of the movable block 204 away from the static disk body 3.

[0038] Please refer again Figure 1 and Figure 3 In order to limit the position of the static plate body 3, the plate mechanism 4 in this embodiment includes a screw 403 fixed to the upper surface of the workbench 1, a rotating drum 402 threadedly connected to the outer surface of the screw 403, a disc 401 rotatably connected to the lower surface of the rotating drum 402 through a bearing seat, a second ring 404 fixed to the lower surface of the disc 401, and a plurality of positioning blocks 405 fixed to the outer surface of the second ring 404. The rotating drum 402 rotates on the screw 403 to drive the disc 401, the second ring 404 and the positioning blocks 405 to move.

[0039] Among them, the positioning block 405 is slidably connected to the inside of the positioning groove 6, and is used to limit the disc 401 to prevent the disc 401 from rotating with the screw rod 403. The lower surface of the disc 401 abuts against the upper surface of the static disc body 3 to limit the static disc body 3 to prevent the static disc body 3 from moving during the correction process.

[0040] The plate mechanism 4 in this embodiment moves the second ring 404 to the interior of the static plate body 3, slides the positioning block 405 to the interior of the positioning groove 6, rotates the rotating drum 402, drives the disc 401 to move downward, makes the disc 401 abut against the static plate body 3, and installs and fixes the static plate body 3 to facilitate shape adjustment.

[0041] The working principle of the above embodiment is:

[0042] (1) When the position of the pressure block 205 needs to be adjusted, the rotating handle is turned, and the rotating handle drives the threaded rod 206 to rotate. Since the two threads of the threaded rod 206 are in opposite directions, the threaded rod 206 rotates, driving the two movable blocks 207 to move in opposite directions at the same time. The movable block 207 drives the slider to slide inside the slide slot, thereby increasing the stability of the movable block 207 when it moves. When the movable block 207 moves, it drives the hinged rod 208 to rotate. The movable block 207 drives the movable plate 209 to slide on the limit rod through the hinged rod 208, and drives the clamping rod 210 By moving the clamping rod 210 away from the clamping slot 211, the connecting rod 203 can be driven to move in the through hole 202 to adjust the position of the pressure block 205. After the adjustment, the rotating handle is rotated in the opposite direction to drive the threaded rod 206 to rotate, so that the two movable blocks 207 move relative to each other at the same time. The movable block 207 drives the movable plate 209 and the clamping rod 210 to move together through the hinged rod 208, so that the clamping rod 210 is clamped into the inside of the clamping slot 211, and the movable block 204 and the pressure block 205 are limited, which makes it convenient to adjust the position of the pressure block 205 and is beneficial to the correction of the static disk body 3.

[0043] (2) Place the static disk body 3 on the first circular ring 201, so that the positioning rod 212 is inserted into the positioning hole 5. Then, move the second circular ring 404 to the inside of the static disk body 3, slide the positioning block 405 into the inside of the positioning groove 6, so that the screw rod 403 is located inside the rotating drum 402, rotate the rotating drum 402, and the rotating drum 402 drives the circular disk 401 to move downward, so that the circular disk 401 abuts against the static disk body 3, and the static disk body 3 is installed and fixed to facilitate the alignment.
