The fixing strips 3 on the top of the base 1 and close to both sides can support the housing 2. The locking component can be used to lock and fix the housing 2, improving the convenience of disassembling and assembling the housing 2 for repairing the base 1.

[0025] In one embodiment, specifically, the latch assembly includes fixing blocks 4 respectively on both sides inside the housing 2. A plurality of fixing grooves 5 arranged uniformly are formed on the other side of the fixing strip 3. A latch groove 501 is formed on the other side of the fixing groove 5. An active through hole 6 is formed inside the inner side of the fixing block 4. The latch assembly further includes a first spring 7 installed inside the active through hole 6 and near one end. The other end of the first spring 7 is fixedly connected to a sliding plate 8. A latch block 9 is welded to one side of the sliding plate 8.

The sliding plate 8 is slidably connected to the active through hole 6. The fixing blocks 4 and the fixing grooves 5 correspond to each other one by one.

[0026] Among them, the plurality of fixing blocks 4 on both sides inside the housing 2 can be embedded into the fixing grooves 5 on one side of the fixing strip 3. The first spring 7 inside the active through hole 6 can push the sliding plate 8 by extrusion, so that the sliding plate 8 pushes the latch block 9 into the latch groove 501 to latch and fix the housing 2, improving the convenience and stability of disassembling and assembling the housing 2.

[0027] Further, the support member includes three I-shaped frames 11 installed at the bottom of the base 1 and arranged uniformly near both sides. A support frame 12 is sleeved on the outside of the I-shaped frame 11 and near the bottom. A backing plate 13 is welded to the bottom of the support frame 12. The buffer assembly includes a plurality of guide rods 14 installed on the inner circumference of the support frame 12. A second spring 15 is sleeved on the bottom of the support frame 12 and outside the guide rods 14.
