The rotating shaft 206 is rotatably sleeved inside the rotating groove 205, which facilitates the rotating support plate 204 to rotate around the rotating shaft 206 inside the adjusting baffle 203. This allows the adjusting wheel 208 to contact the outer wall of the electromechanical device to be repaired, making it easier for the electromechanical device to be repaired to rotate outside the adjusting wheel 208, thereby facilitating the adjustment of the position of the electromechanical device to be repaired inside the arc-shaped base plate 201.

Moreover, by pressing the toggle arc plate 215, the limiting baffle 214 is moved, which is convenient for moving the limiting block 216 out of the limiting slot 217.
[0023] A limiting block 216 is provided on the outer wall of the limiting baffle 214. The shape of the limiting block 216 is adapted to the shape of the limiting groove 217.

[0024] The side wall of the adjusting baffle 203 is provided with a limiting slider 219, and the inside of the adjusting slide 202 is provided with a limiting slide 218. The limiting slider 219 is slidably sleeved inside the limiting slide 218. The limiting slider 219 is located on both sides of the adjusting baffle 203 and has a mirror symmetrical structure. The shape of the limiting slider 219 is adapted to the shape of the limiting slide 218. The limiting slide 218 is located on the inner wall of the adjusting slide 202. During the process of adjusting the position of the adjusting baffle 203 inside the adjusting slide 202, the limiting slider 219 is positioned inside the limiting slide 218, thereby restricting the movement direction of the adjusting baffle 203.

The placement hole 221 is located inside the fixed bracket 220, and the positioning pin 222 is installed inside the placement hole 221. By passing the positioning pin 222 through the placement hole 221 and installing it inside the fixed hole 103, it is convenient to install the auxiliary tooling 2 to the outside of the lifting platform 102, which facilitates positioning and maintenance of irregular electromechanical parts.
[0026] A specific application of this embodiment is as follows: By installing the fixed bracket 220 to the outside of the lifting platform 102 and installing the positioning pin 222 through the placement hole 221 into the fixed hole 103, the auxiliary tooling 2 is then installed to the outside of the lifting platform 102. The equipment to be repaired is then placed inside the arc-shaped base plate 201. By adjusting the position of the adjusting baffle 203 within the adjusting groove 202, and under the push of the elastic arc plate 213, the limiting baffle 214 contacts the inner wall of the adjusting groove 202. Simultaneously, the limiting block 216 is fixedly sleeved inside the limiting groove 217, thereby locking the position of the adjusting baffle 203. This allows the adjusting baffle 203 to be used to position and clamp the irregularly shaped equipment to be repaired, preventing the equipment from shifting during the repair process. If the irregular equipment is misaligned or rolling, affecting the maintenance of the equipment to be repaired, then when it is necessary to adjust the position of the irregular equipment to be repaired inside the auxiliary fixture 2, the rotating support plate 204 is rotated around the rotating shaft 206 to adjust the position of the rotating support plate 204 inside the adjusting baffle 203, so that the outer wall of the adjusting wheel 208 contacts the outer wall of the irregular equipment to be repaired. Then, under the push of the elastic support plate 212, the limit stop 211 contacts the outer wall of the adjusting baffle 203, thereby locking the position of the adjusting wheel 208. Then, by adjusting the position of the irregular equipment to be repaired, the equipment to be repaired can rotate on the outer wall of the adjusting wheel 208, thereby adjusting the position of the equipment to be repaired inside the auxiliary fixture 2, which facilitates the maintenance of the equipment to be repaired.
