In the production process, different types of sensors are used to monitor and control parameters in a production link so as to enable equipment to keep a normal working state, for example, in chain type conveying equipment, a position detection sensor is often arranged on the side edge of a conveying belt to detect whether conveyed materials reach a target position. In order to avoid direct collision of the sensor body with the transported material during production and transportation, a protective device or a bracket is usually arranged outside the sensor.

For example, the utility model of publication number CN218121010U provides a sensor guard comprising a connection structure and a guard structure. The connecting structure comprises a sleeve, an elastic piece and a movable piece, wherein one end of the sleeve is provided with an opening, sliding grooves are formed in two sides of the sleeve, the elastic piece is installed in the sleeve, the movable piece is slidably connected to the sleeve, a sensor main body is installed on the movable piece, the protecting structure comprises a protecting cover, the protecting cover is slidably sleeved on the surface of the sleeve, and the protecting cover is installed on the movable piece. When the sensor main body is impacted, the protection device can drive the sensor to move, so that the buffer space of the sensor when the sensor main body is impacted is increased, the damage probability of the sensor is reduced, but the sensor main body can stretch and retract under the action of the elastic piece and cause movement of detection signals, and the detection result of the sensor deviates from the preset detection position.
