By providing the screw 20, the two positioning plates 19 can be driven to approach or move away from each other. The screw 20 is a bidirectional screw, and one end of the screw 20 is fixedly connected to a knob 21.

[0036] During use, by rotating the knob 21, the rotation of the knob 21 will drive the screw 20 to rotate. The rotation of the screw 20 will drive the two positioning plates 19 to move away from each other. The two positioning plates 19 moving away from each other can release the fixed connection to the connecting block 8, and further the damper 15 and the damper spring 16 can be disassembled, which is convenient for replacing and maintaining them and improves work efficiency.

[0037] Refer to Figure 4, one end of the screw rod 20 is rotatably installed with a fixing plate 22, and the fixing plate 22 is fixedly installed in the installation groove 7. By providing the fixing plate 22, the screw rod 20 can be supported and installed.

[0038] Refer to Figure 4 , on both outer walls of the connecting block 8, card slots 23 are provided. In both card slots 23, card blocks 24 are slidably installed, and the two card blocks 24 are respectively fixedly connected to the corresponding positioning plates 19.

[0044] The implementation principle of this application is as follows: When in use, a control instruction is sent by the AGV controller to the driver 2, and the driver 2 drives the motor 1 according to the control instruction. Then, the motor 1 further drives the driving wheel 4 to act. Two shock-absorbing plates 5 are installed radially on the output shaft of the motor 1 and are connected to the AGV body through the two shock-absorbing plates 5. When the driving wheel 4 has undulations in its radial direction during travel, the AGV body will achieve buffering and shock absorption through the damper 15 and the damping spring 16.

[0045] When it is necessary to disassemble, replace or maintain the damper 15 and the damping spring 16, first rotate the two guide shafts 11. The rotation of the two guide shafts 11 can release the fixed connection with the mounting seat 6.

[0046] By rotating the two nuts 28 and removing the two nuts 28, the two plug posts 27 can also be removed. At this time, the connection and fixation of the two shock-absorbing plates 5 can be released.

[0047] At this time, the knob 21 can be rotated again. The rotation of the knob 21 will drive the screw rod 20 to rotate. The rotation of the screw rod 20 will drive the two positioning plates 19 to move away from each other. The two positioning plates 19 moving away from each other can release the fixed connection of the connecting block 8, and then the damper 15 and the damping spring 16 can be disassembled, which is convenient for replacement and maintenance and improves work efficiency.
