[0029] The positioning mechanism 2 includes a motor plate 201, the outer wall of which is fixedly connected to the outer wall of the main board 1. The main board 1 fixes the position of the slide rail 101, preventing positional changes during use that could affect the normal operation of the device. A controller 202 is fixedly connected to the outer wall of the motor plate 201. A self-locking motor 203 is fixedly connected to the outer wall of the motor plate 201 near the controller 202. A rotating shaft 204 is fixedly connected to the bottom output shaft of the self-locking motor 203 via a coupling. A gear 205 is fixedly connected to the outer wall of the rotating shaft 204 away from the self-locking motor 203. The motor plate 201 fixes the position of the self-locking motor 203, preventing positional changes during operation that could damage it. A rotating shaft 206 is rotatably connected to the inner wall of the main board 1. Gear 207 is fixedly connected to the outer wall of shaft 206 near gear 205. The outer wall of gear 207 meshes with the outer wall of gear 205. A rotating plate 208 is fixedly connected to the outer wall of shaft 206 away from gear 207. The rotation of gear 205 drives gear 207 to rotate, preventing gear 207 from affecting the rotation of gear 205 and causing the device to jam. The inner wall of rotating plate 208 has several sliding grooves 209. Several sliding rods 210 are slidably connected to the inner wall of rotating plate 208. The outer walls of several sliding rods 210 are slidably connected to the inner wall of slide rail 101. A buffer mechanism 3 is provided on the outer wall of main plate 1. The slide rail 101 enables the sliding rods 210 to move stably, avoiding the problem of the sliding rods 210 rotating during movement and preventing the device from being unable to perform positioning processing.

[0030] A positioning block 211 is fixedly connected to the outer wall of the end of the sliding rod 210 away from the slide rail 101. The inner wall of the positioning block 211 is provided with several anti-slip grooves 212. A circuit board 213 is slidably connected to the outer wall of the sliding rod 210. The buffer mechanism 3 includes several dampers 301. The outer walls of the dampers 301 are fixedly connected to the outer wall of the main board 1. The anti-slip grooves 212 fix the position of the circuit board 213, preventing the circuit board 213 from falling off during use and causing the device to become unusable. A spring 302 is sleeved on the outer wall of the damper 301. The outer wall of the spring 302 is fixedly connected to the outer wall of the main board 1. A base plate 303 is fixedly connected to the outer wall of the end of the spring 302 away from the main board 1. A support rod 304 is fixedly connected to the inner wall of the base plate 303. The base plate 303 fixes the position of the support rod 304, preventing the support rod 304 from falling off during use and affecting the normal use of the device.

[0031] A second spring 305 is fitted onto the outer wall of the support rod 304. A rotating shaft 306 is rotatably connected to the inner wall of the main board 1 near the base plate 303. A rotating block 307 is fixedly connected to the outer wall of the rotating shaft 306 away from the main board 1. The main board 1 ensures stable rotation of the rotating shaft 306, preventing it from flipping during rotation and causing the device to malfunction. A second rotating shaft 308 is fixedly connected to the outer wall of the rotating block 307 away from the rotating shaft 306. A sliding block 309 is rotatably connected to the outer wall of the second rotating shaft 308. The inner wall of the sliding block 309 is slidably connected to the outer wall of the support rod 304, and the outer wall of the sliding block 309 is fixedly connected to the outer wall of the second spring 305. The sliding block 309 ensures stable rotation of the second rotating shaft 308, preventing it from shifting during rotation and causing the device to jam.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, first, the circuit board 213 is placed on the contact position of the positioning block 211 on one side. Then, the self-locking motor 203 is started by the controller 202. The self-locking motor 203 causes the rotating shaft 204 to rotate. The rotating shaft 204 drives the gear 205 to rotate. The rotation of the gear 205 drives the second gear 207 to rotate. The second gear 207 drives the second rotating shaft 206 to rotate. The second rotating shaft 206 drives the rotating plate 208 to rotate. The rotation of the rotating plate 208 causes multiple sliding rods 210 to slide in the sliding groove 209. At the same time, the sliding rods 210 move in the slide rail 101. The slide rail 101 is used to prevent the sliding rods 210 from deflecting during the movement. Then, the sliding rods 211 drive the positioning block 211 to move. The movement of multiple positioning blocks 211 fixes the position of the circuit board 213, completing the electrical connection. The positioning of the circuit board 213 utilizes the anti-slip groove 212 to prevent the circuit board 213 from falling off the device during component arrangement. When the device is affected by external vibration, the main board 1 will drive the aforementioned components to compress the damper 301 and spring 302. The main board 1 will move up and down repeatedly through the damper 301 and spring 302. At the same time, the main board 1 will drive the rotating shafts 306 at both ends to move. Since the rotating shafts 306 are restricted by the rotating block 307 when they move, the rotating shafts 306 will drive the rotating block 307 to rotate. The rotating block 307 will drive the second rotating shaft 308 to rotate. When the second rotating shaft 308 rotates, it will drive the sliding block 309 to move and compress the second spring 305. This process is repeated to buffer the device by the movement of the damper 301 and the second rotating shaft 308.
