[0016] The effect achieved by the above components is: when using the auxiliary device, the placement block can be moved so that the placement block contacts the L-shaped plate, and then the bolt is turned so that the bolt passes through the L-shaped plate and the connecting plate to fix it, and then the position of the placement block is fixed. By using the installation assembly, the auxiliary device can be quickly fixed to the protective plate, so that the auxiliary device can be used conveniently.

[0017] Preferably, one side of the bolt is abutted against a gasket, and one side of the gasket is adapted to the size of the bolt.

[0018] The effect achieved by the above components is: by using the gasket, the contact area between the bolt and the L-shaped plate is increased, so that the bolt can fix the connecting plate more firmly.

[0019] Preferably, an operating block is fixedly connected to one side of the bolt, and the size of the operating block is matched with the size of the bolt.

[0020] The effect achieved by the above components is: by using the operating block, the contact area between the operating block and the operator is increased, so that the bolt can be turned more easily.

By using the telescopic rod 25, the shape of the spring 23 is restricted, so that the spring 23 can be used more stably. The inner wall of the placement block 21 is fixedly connected with an arc bar 26, and the arc surface of the arc bar 26 is smooth. By using the arc bar 26, the friction between the placement block 21 and the auxiliary block 22 is reduced, so that the auxiliary block 22 is more easily reset by the spring 23.

When the foreign object approaches the four walls of the protective plate 1, it will be intercepted by the auxiliary block 22, and then the auxiliary block 22 will be forced to slide inside the placement block 21 with the arc bar 26. At this time, the spring 23 will be compressed, and the telescopic rod 25 will be shortened. Then, after the force of the foreign object disappears, the spring 23 on the fixed plate 24 will reset, and then drive the auxiliary block 22 to reset, so that the foreign object will not cause significant damage to the protective plate 1. By using the auxiliary device 2, it can be buffered when the object reaches the four walls of the protective plate 1, so that the object will not cause significant damage to the protective plate 1, thereby increasing the service life of the protective plate 1, and then improving the use effect of the protective device.

Then, the position of the placement block 21 is fixed. By using the mounting assembly 3, the auxiliary device 2 can be quickly fixed to the protective plate 1, so that the auxiliary device 2 can be used conveniently.
