Description

Technical Field

[0001] The present disclosure relates to the technical field of auxiliary tools, and in particular, to a grating alignment tool. Background Art

[0002] The beam fence includes a light-emitting fence and a light-receiving fence. The light-emitting fence emits infrared rays to irradiate the light-receiving fence. When an object blocks the infrared rays from irradiating the light-receiving fence, the light fence triggers an alarm. Therefore, the light-emitting fence and the light-receiving fence must be aligned with each other during installation. The length of the light-emitting fence and the light-receiving fence varies from tens of centimeters, and the installation distance is between one meter and several meters depending on the usage scenario. Infrared rays are invisible light, so the alignment work is blind adjustment, which is time-consuming and laborious. Utility Model Content
