[0009] Furthermore, the front frame is provided with a slot, and the ear plate mates with the slot. The slot allows the ear plate to be aligned more quickly, facilitating the alignment of the second screw hole and the third screw hole.

[0010] Furthermore, the anti-theft panel is provided with a fourth screw hole and an oblong hole, the mounting base box is provided with a limiting post, and the front frame is provided with a fifth screw hole; the fourth screw hole and the fifth screw hole mate, and the limiting post is inserted into the oblong hole. In application, the limiting post is first inserted into the oblong hole, and then the screws are passed through the fourth screw hole and the fifth screw hole, thereby binding the front frame to the mounting base box to achieve anti-theft.

[0011] Furthermore, an operating groove is provided at the bottom of the front frame, and the fifth screw hole is located within the operating groove. One end of the anti-theft plate is inserted into the operating groove. The operating groove facilitates the screwing of screws into the fourth and fifth screw holes. Preferably, there are two operating grooves.

[0012] Using the above solution, this utility model provides an externally mounted floor selector. During installation, the panel is mounted on the front frame, the front frame is mounted on the rear cover, and the first and second buckle components are directly engaged to mount the front frame and rear cover onto the mounting base box. At the same time, the anti-theft plate is connected to the front frame and the mounting base box to achieve the anti-theft function. Attached Figure Description
