Mounting device of proximity switch

The embodiment of the utility model discloses a mounting device of a proximity switch. The mounting device comprises a mounting bracket, a stop block, a first pulley block, a second pulley block and a steel wire rope. According to the mounting device of the proximity switch, the impact force produced by the stop block in movement is buffered through pulleys and the steel wire rope so as to prevent the proximity switch from being crashed by the stop block. The mounting position of the proximity switch can also be adjusted on the mounting bracket under the condition that equipment operates, and the damaged proximity switch can also be replaced at any time; the mounting device has the advantages of simple and light structure, flexible operation, high reliability, easiness in assembly and the like.
