A bolt 24 is threadedly inserted on one side of the first protective plate 22, and a connecting plate 25 is threadedly connected to the surface of the bolt 24, and a second protective plate 26 is fixedly connected to one side of the connecting plate 25, and a second sliding block 27 is slidably connected to one side of the second sliding block 27, and a clamping block 28 is fixedly connected to one side of the second sliding block 27, and one side of the clamping block 28 is clamped with the first sliding block 23.
[0030] Reference Figure 1-4 As shown, this embodiment discloses that before using the spring 4, the second protective plate 26 can be moved so that one side of the second protective plate 26 is inserted into the first protective plate 22, and then the block 28 on the second sliding block 27 on one side of the second protective plate 26 is clamped and fixed with the first sliding block 23, and then the bolt 24 is rotated so that the bolt 24 passes through the first protective plate 22 and is fixed to the second protective plate 26, and then the first protective plate 22 and the second protective plate 26 are both fixed to the surface of the ring 21 on the placement column 1, and the first protective plate 22 and the second protective plate 26 cooperate with the first sliding block 23 and the second sliding block 27 to form a protective cover to shield and protect the spring 4. By using the protective device 2, the spring 4 on the placement column 1 can be shielded and protected to prevent debris from entering the gap of the spring 4 and then affecting the compression deformation of the spring 4, thereby improving the use effect of the buffer component.
[0031] Reference Figure 1-4As shown, this embodiment discloses that one side of the bolt 24 abuts against a gasket 29, and one side of the gasket 29 abuts against the first protective plate 22. By using the gasket 29, the contact area between the bolt 24 and the first protective plate 22 is increased, so that the bolt 24 can fix the connecting plate 25 more firmly. One side of the connecting plate 25 is fixedly connected to a reinforcing plate 210, and one side of the reinforcing plate 210 is fixedly connected to the second protective plate 26.

When moving the second sliding block 27, the operator can hook the control ring 33 with his finger, and then drive the round rod 32 with the bearing 34 to rotate on one side of the fixed block. The operator then controls the movement of the second sliding block 27 through the control ring 33. By using the control assembly 3, the contact area between the second sliding block 27 and the operator can be increased, making it easier for the operator to move the second sliding block 27.

The spring 4 will move away from the placement column 1, and the part close to the protective device 2 will be connected to the pin 5, so that the pin 5 has a buffer function. Before using the spring 4, the second protective plate 26 can be moved so that one side of the second protective plate 26 is inserted into the first protective plate 22, and then the block 28 on the second sliding block 27 on one side of the second protective plate 26 is engaged and fixed with the first sliding block 23, and then the bolt 24 is rotated so that the bolt 24 passes through the first protective plate 22 and is fixed to the second protective plate 26. Then the first protective plate 22 and the second protective plate 26 are both fixed to the surface of the ring 21 on the placement column 1, and the first protective plate 22 and the second protective plate 26 cooperate with the first sliding block 23 and the second sliding block 27 to form a protective cover to block and protect the spring 4. By using the protective device 2, the spring 4 on the placement column 1 can be blocked and protected to prevent debris from entering the gap of the spring 4, which will then affect the compression deformation of the spring 4, thereby improving the use effect of the buffer assembly.
[0035] When moving the second sliding block 27, the operator can hook the control ring 33 with his fingers, and then drive the round rod 32 with the bearing 34 to rotate on one side of the fixed block. Then the operator controls the movement of the second sliding block 27 through the control ring 33. By using the control component 3, the contact area between the second sliding block 27 and the operator can be increased, making it easier for the operator to move the second sliding block 27.
