[0009] By adopting the above technical solutions, a heat dissipation structure is added, and a fan is added to quickly dissipate the heat inside the lower housing through the fan, and at the same time, dust-proof treatment is carried out in cooperation with the dust-proof net.

[0010] Furthermore, there are two sets of the empty slots, fixing blocks, cover plates, damping rotating shafts and wire grooves symmetrically arranged. Each set of fixing blocks has two, and each set of wire grooves has multiple arranged at equal intervals. The cover plate and the fixing block are rotatably connected through the damping rotating shaft, and the cover plate and the empty slot are mutually adapted.

[0011] By adopting the above technical solution, through the design of the symmetrical structure, installation and use can be carried out from both sides, and the damping rotating shaft can adjust the rotation angle, which is convenient for installation and use.

[0012] Furthermore, the clamping block is clamped inside the clamping groove and is connected with the clamping groove through interference fit. There are two sets of the blowers symmetrically arranged, and each set of blowers has multiple arranged at equal intervals.

[0013] By adopting the above technical solution, through the interference fit connection, the clamping block and the clamping groove can be connected to realize the connection between the upper shell and the lower shell, with a simple structure and convenient operation.

[0015] By adopting the above technical solution, through the heat dissipation holes, the heat dissipation effect can be improved to achieve rapid heat dissipation.

[0016] In summary, the beneficial technical effects of the present utility model are as follows:

[0017] 1. The cover plate, damping rotating shaft and wire groove are adopted. The cover plate is arranged outside the empty slot, which can protect the empty slot. At the same time, when the controller inside the shell is wired, the wire harness can pass through the inside of different wire grooves to classify and organize the wire harnesses of different interfaces, producing the effect of convenient use;

[0018] 2. The clamping block, clamping groove and blower are adopted. The upper shell and the lower shell are connected and installed through the interference fit connection between the clamping block and the clamping groove, and then heat dissipation treatment is carried out through the blower to dissipate heat from the controller, producing the effect of stable operation.
