[0021] As a technical optimization solution of the utility model, Figure 1 and Figure 3 As shown, the cross-section of the top of the sliding sleeve 301 is a T-shaped structure, and the four sliding sleeves 301 are arranged at the four corners of the main board body 2. Four through holes are arranged at the four corners of the main board body 2. The outer diameter of the shock-absorbing rubber ring 303 is equal to the diameter of the through hole, so the shock-absorbing rubber ring 303 can pass through the through hole to limit the main board body 2.

[0022] As a technical optimization solution of the utility model, Figure 2 As shown, two mounting holes 5 are provided on the bottom plate 1 , and the two mounting holes 5 are symmetrically distributed about the middle of the bottom plate 1 , so the bottom plate 1 can be installed and fixed by means of the mounting holes 5 and screws.

[0023] As a technical optimization solution of the utility model, Figure 3 and Figure 4 As shown, the fixed structure 4 includes a pressing block 401 and a sliding block 402, the top of the pressing sleeve 304 is slidably connected with the pressing block 401, the bottom end of the pressing block 401 is fixedly connected with the sliding block 402, the sliding block 402 is slidably connected to the pressing sleeve 304, and the inside of the pressing sleeve 304 is slidably connected with two clamping blocks 404, one end of the clamping block 404 is engaged with the sliding sleeve 301, and the top of the clamping block 404 is fixedly connected with a stopper 403, the top ends of the two stopper blocks 403 are in contact with the bottom end of the sliding block 402, and a return spring 405 is provided inside the pressing sleeve 304, one end of the return spring 405 is in contact with one of the clamping blocks 404, and the other end of the return spring 405 is in contact with the other clamping block 404, so that the pressing sleeve 304 and the sliding sleeve 301 can be quickly separated, thereby realizing the rapid disassembly of the mainboard body 2.

[0025] As a technical optimization solution of the utility model, Figure 4 As shown, the cross section of one end of the clamping block 404 is a trapezoidal structure, and the cross section of the entire clamping block 404 is an L-shaped structure, so it can play a guiding role when the clamping block 404 is engaged with the sliding sleeve 301.

[0026] When the utility model is in use, the bottom plate 1 can be installed on the mobile phone by screwing the mounting holes 5, and then the main board body 2 can be moved and the four shock-absorbing rubber rings 303 can be simultaneously passed through the four through holes at the four corners of the main board body 2, so that the main board body 2 is limited. Then the pressing sleeve 304 can be moved toward the sliding sleeve 301 and the pressing sleeve 304 can be engaged with the sliding sleeve 301. When the pressing sleeve 304 is completely engaged with the sliding sleeve 301, its bottom end will be in conflict with the main board body 2.

At this time, the pressing sleeve 304 cannot be separated from the sliding sleeve 301. Repeat the above operation so that the bottom ends of the four pressing sleeves 304 are in conflict with the main board body 2. At this time, the main board body 2 is fixed. When vibration occurs during use, the shock-absorbing spring 302 can be used for buffering and shock reduction. The function is that by setting the shock-absorbing rubber ring 303, it is possible to achieve shock absorption of vibrations in different directions, thereby effectively improving the shock absorption effect. By damping the shock of the main board body 2, it is possible to prevent the main board body 2 from being damaged by large vibrations, thereby effectively improving the safety of use. When the main board body 2 is damaged and needs to be disassembled for inspection and repair, the pressing block 401 can be pressed, and the pressing block 401 drives the slider 402 to move. The slider 402 resists the movement of the two stoppers 403, and the stopper 403 drives the clamping block 404 to move away from the sliding sleeve 301, and the reset spring 405 contracts. When one end of the clamping block 404 is not engaged with the sliding sleeve 301, the pressing sleeve 304 can be moved and separated from the sliding sleeve 301. When the four pressing sleeves 304 are removed from the sliding sleeve 301, the main board body 2 can be removed, thereby realizing the rapid disassembly of the main board body 2, which is convenient for the inspection and maintenance of the main board body 2.
