[0030] As shown in Figures 1-5 , as a preferred embodiment, on the basis of the above mode, further, the adjusting groove 102 is symmetrically provided with two about the central axis of the moving frame 103, by setting two adjusting grooves 102, the stability of the moving frame 103 when sliding can be improved.

[0031] As shown in Figures 1-4 , as a preferred embodiment, on the basis of the above mode, further, the first mounting ring 100 and the second mounting ring 101 are both connected with a filling pipe 110, the outer side wall of the first mounting ring 100 and the second mounting ring 101 is fixedly connected with a storage box 111, further comprising a first pump body 112, one end of the first pump body 112 is fixedly connected with a connecting pipe 113, the end of the connecting pipe 113 away from the first pump body 112 is communicated with the filling pipe 110, the other end of the first pump body 112 is communicated with the storage box 111, by starting the first pump body 112, the lubricating oil in the storage box 111 is delivered into the filling pipe 110, so that the filling pipe 110 is expanded, which is conducive to further improving the damping effect.

[0032] As shown in Figures 1-4 , as a preferred embodiment, on the basis of the above mode, further, the first mounting ring 100 and the second mounting ring 101 are fixedly connected with a spraying plate 114, the spraying plate 114 is fixedly connected with a conveying pipe 115, further comprising a second pump body 116, one end of the second pump body 116 is communicated with the storage box 111, the other end is communicated with the conveying pipe 115, the inner side wall of the spraying plate 114 is provided with uniformly distributed spraying grooves 117, by the second pump body 116, the lubricating oil is pumped through the conveying pipe 115 into the spraying plate 114, and is sprayed onto the damping column 105 by the spraying groove 117, which is conducive to reducing the friction between the damping column 105 and the fixed ring 121, so as to improve the service life of the damping column 105.
