Photoelectric sensor with protection structure

The invention discloses a photoelectric sensor with a protection structure, and relates to the technical field of photoelectric sensors, the photoelectric sensor comprises a protection shell, a sensor body is installed in the protection shell, and the protection structure comprises a straight gear, a first connecting rod, a second connecting rod, a first spring, a third connecting rod, a rack, a movable block and an adjusting screw rod; a protection structure is arranged, a protection plate moves towards the side close to a protection shell, a first connecting rod drives a first straight gear and a sixth straight gear to rotate, the straight gears drive racks to move, a second spring and a fifth spring play a role in damping, meanwhile, the remaining four straight gears rotate, a mounting plate is driven by a second connecting rod to move upwards, and the protection plate is driven to move upwards. And a mounting plate extrudes a first spring, the first spring achieves a better damping effect, a third straigh
