Two sets of springs 107 and damping rods 108 are fixedly installed on the side of the linkage plate 105. A mounting housing 106 is fixedly connected to the other side of the two sets of springs 107 and damping rods 108. The carrier plate 1 is fixedly connected to the side of the mounting housing 106. A connecting arm 104 is fixedly connected to the top of the linkage plate 105. The other end of the connecting arm 104 is fixedly connected to... An upper housing 3 is attached, and a lower housing 4 is attached to the side of the upper housing 3. A support plate 1 is fixedly connected to the bottom of the lower housing 4. A photoelectric Hall sensor body 5 is installed inside the upper housing 3 and the lower housing 4. A linkage plate 105, fixedly connected by a connecting arm 104, slides on the surface of two sets of limiting guide rods 103. During the sliding process, two sets of springs 107 and damping rods 108 on the side of the linkage plate 105 form elastic tension inside the mounting housing 106, thereby causing the upper housing 3 to slide on the side of the support plate 1. Then, the interface of the photoelectric Hall sensor body 5 is aligned with the opening of the lower housing 4, and the upper housing 3 is released. Under the elastic potential energy of the two sets of springs 107 and damping rods 108, the upper housing 3 and lower housing 4 are brought together to shield and protect the photoelectric Hall sensor body 5. Then, mounting bolts 302 are used to pass through the extension plates 301 on both sides of the upper housing 3 and lower housing 4 for fastening. The connecting shaft 2 at the other end of the connecting arm 201, which is fixedly connected to the steel protective housing 202, rotates on the right side of the bearing plate 1, causing the steel protective housing 202 and the bearing plate 1 to come together. Fastening bolts 204 are then used to pass through the mounting plate 203 and the bearing plate 1 for further fastening, forming additional protection. Extension plates 301 are fixedly installed on both sides of the upper housing 3 and lower housing 4. The extension plate 301 has internal threaded connections to mounting bolts 302. Mounting screw grooves 101 are respectively opened at the four corners of the bearing plate 1. The bottom of the upper housing 3 is attached to the top of the bearing plate 1. The right side of the bearing plate 1 has a mounting groove. The mounting groove is rotatably connected to the inside of the mounting groove.

The other end of the second connecting arm 201 is fixedly installed with a steel protective housing 202. The left side of the steel protective housing 202 is fixedly connected to a mounting plate 203. Both the bearing plate 1 and the mounting plate 203 have screw holes. The internal threads of the screw holes are connected to fastening bolts 204.

[0021] The working principle is as follows: the linkage plate 105, which is fixedly connected by the connecting arm 104, slides on the surface of the two sets of limiting guide rods 103. During the sliding process, the two sets of springs 107 and damping rods 108 on the side of the linkage plate 105 form elastic tension inside the mounting housing 106, thereby causing the upper housing 3 to slide on the side of the support plate 1. Then, the interface of the photoelectric Hall sensor body 5 is aligned with the opening of the lower housing 4, and the upper housing 3 is released. Under the action of the elastic potential energy of the two sets of springs 107 and damping rods 108, the upper housing 3 and the lower housing 4 are attached to form a shield and protection for the photoelectric Hall sensor body 5. Then, the mounting bolts 302 are used to pass through the extension plates 301 on both sides of the upper housing 3 and the lower housing 4 to complete the fastening. Then, the connecting shaft 2 at the other end of the connecting arm 201, which is fixedly connected by the steel protective housing 202, rotates on the right side of the support plate 1, thereby causing the steel protective housing 202 and the support plate 1 to be attached. The fastening bolts 204 are used to pass through the mounting plate 203 and the support plate 1 to complete the fastening, forming further protection.
