At this time, the fixing rod slides on the inner wall of the mounting slot. When the fixing rod moves to the position of the fixing slot, the fixing rod is inserted into the fixing slot under the action of the fixing spring, thereby achieving fixed installation of the mounting block. Then the operator uses the anti-collision airbag to prevent the lawn mower from being damaged by collision. When the anti-collision airbag is damaged, the operator uses the driving assembly to move the fixing rod out of the fixing slot. Then the operator takes out the mounting block and replaces the new anti-collision airbag. Only the damaged anti-collision airbag needs to be replaced, and the lawn mower and the shell do not need to be replaced as a whole, which greatly reduces the maintenance cost.
[0025] 2. When the anti-collision airbag is hit, it is squeezed, and part of the gas in the anti-collision airbag enters the buffer airbag, reducing the pressure on the anti-collision airbag, thereby reducing the damage caused by the squeezing, expansion and deformation of the anti-collision airbag;
[0026] 3. When the anti-collision airbag is damaged, the gas in the anti-collision airbag will be lost. At this time, the gas in the buffer airbag will all enter the anti-collision airbag and be lost under the action of the moving plate.

[0041] Reference Figure 3 The movable plate 25 is provided with a connecting rod 272, which is horizontally arranged and arranged at both ends of the movable plate 25. The connecting rod 272 is fixedly connected to the movable plate 25, and a support rod 27 is arranged on the end of the connecting rod 272 away from the movable plate 25. The support rod 27 is horizontally arranged and sleeved on the connecting rod 272. The support rod 27 is slidably penetrated on the mounting block 2, and an anti-collision plate 271 is arranged on the end of the support rod 27 passing through the mounting block 2.
[0042] When the anti-collision airbag 21 is damaged, the gas in the anti-collision airbag 21 is lost. At this time, the gas in the buffer airbag 23 all enters the anti-collision airbag 21 and is lost under the action of the movable plate 25. The movable plate 25 drives the support rod 27 to move under the action of the movable spring 26. The movement of the support rod 27 drives the anti-collision plate 271 to move. The anti-collision plate 271 supports the anti-collision airbag 21 from the inside, thereby temporarily replacing the anti-collision airbag 21 to play a buffering role, thereby reducing the impact on the lawn mower.
[0043] Reference Figure 3 The anti-collision plate 271 is vertically arranged, and is in the shape of a rectangular plate. The anti-collision plate 271 is arranged in the anti-collision airbag 21, and both ends of the anti-collision plate 271 are fixedly connected to the support rod 27.

[0044] The anti-collision airbag 21 is squeezed, and part of the gas in the anti-collision airbag 21 enters the buffer airbag 23. The inner wall of the anti-collision airbag 21 touches the anti-collision plate 271. The anti-collision plate 271 drives the connecting rod 272 to move under the action of the anti-collision airbag 21. The movement of the connecting rod 272 makes the connecting spring 274 in a compressed state, reducing the pressure on the anti-collision airbag 21, thereby preventing the anti-collision airbag 21 from being squeezed, expanded, deformed and damaged.
[0045] The implementation principle of an anti-collision automatic lawn mower in an embodiment of the present application is as follows: an operator inserts the mounting block 2 into the mounting slot 12, at which time the fixing rod 13 slides on the inner wall of the mounting slot 12, and when the fixing rod 13 moves to the position of the fixing slot 14, the fixing rod 13 is inserted into the fixing slot 14 under the action of the fixing spring 16, thereby achieving fixed installation of the mounting block 2.
[0046] When the anti-collision airbag 21 is hit, it is squeezed, and part of the gas in the anti-collision airbag 21 enters the buffer airbag 23. The inner wall of the anti-collision airbag 21 touches the anti-collision plate 271. The anti-collision plate 271 drives the connecting rod 272 to move under the action of the anti-collision airbag 21. The movement of the connecting rod 272 makes the connecting spring 274 in a compressed state, reducing the pressure on the anti-collision airbag 21 when it is hit, thereby preventing the anti-collision airbag 21 from being squeezed, expanded, deformed, and damaged.
[0047] When the anti-collision airbag 21 is damaged, the gas in the anti-collision airbag 21 and the buffer airbag 23 is lost, so that the movable plate 25 drives the support rod 27 to move under the action of the movable spring 26, and the support rod 27 supports the anti-collision airbag 21 from the inside through the anti-collision plate 271, thereby temporarily replacing the anti-collision airbag 21 to play a buffering role and reducing the impact on the lawn mower.
[0048] When the anti-collision airbag 21 needs to be replaced, the operator presses the driving rod 32, and the driving rod 32 drives the fixing rod 13 to move out of the fixing slot 14 through the driving block 31. Then the operator takes out the mounting block 2. Only the damaged anti-collision airbag 21 needs to be replaced, and there is no need to replace the lawn mower and the shell as a whole, which greatly reduces the maintenance cost.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
