[0036] A lower frame body 100, on which an installation groove 111 is provided, and the installation groove 111 has a locking opening 1111 with an upward opening and a pressing opening 1112 with an outward opening;

[0037] An upper frame body 200, and a locking hook 210 extends downward from the bottom of the upper frame body 200;

[0038] The locking component 300 includes an elastic member 320 and a lock block 310. The elastic member 320 and the lock block 310 are installed in the installation groove 111. The lock block 310 is hinged and extends into the lock opening 1111. The elastic member 320 abuts against one end of the lock block 310 away from the lock opening 1111. The elastic member 320 keeps the lock block 310 and the lock hook 210 extending into the lock opening 1111 in a locked state. When the lock block 310 receives a pressing force from outside the pressing port 1112, the lock block 310 rotates and disengages from the lock hook 210.

[0039] During installation, align the upper frame body 200 and the lower frame body 100. The lock hook 210 extends into the lock opening 1111 and locks with the lock block 310. The elastic member 320 makes the lock block 310 always fit against the lock hook 210, avoiding the risk of easy loosening. During disassembly, press the lock block 310 through the pressing port 1112. The lock block 310 rotates and disengages from the lock hook 210, so that the upper frame body 200 and the lower frame body 100 can be separated. Due to the abutment of the elastic member 320, a certain force is required during pressing, which can reduce the risk of accidental touch.

[0040] Please refer to Figure 3 、 Figure 5 and Figure 6 It further includes a spring pin 400. The spring pin 400 is arranged on the mating end face of the lower frame body 100 and / or the upper frame body 200. When the lower frame body 100 and the upper frame body 200 are separated, the spring pin 400 protrudes. When the lower frame body 100 and the upper frame body 200 are locked, the spring pin 400 is recessed and makes the upper frame body 200 and the lower frame body 100 have a separating force. By setting the spring pin 400, when it is necessary to separate the upper frame body 200 and the lower frame body 100, press the lock block 310 through the pressing port 1112. Under the action of the restoring force of the spring pin 400, the upper frame body 200 and the lower frame body 100 are automatically separated, facilitating the disassembly of the upper frame body 200 and the lower frame body 100. At the same time, due to the separating force of the spring pin 400, the lock hook 210 and the lock block 310 can be closely fitted.
