Preferably, a dust screen is fixedly inserted into the inner top of the through opening.

Preferably, a limiting sleeve is fixedly sleeved at one end of the glass plate far away from the fixing plug.

Preferably, a sealing ring is fixedly sleeved at one end of the laser diode, which is located in the device box, and one side of the sealing ring is abutted against the inner wall of the device box.

Preferably, the clamping rod is sleeved with a spring, and two ends of the spring are fixedly connected with the clamping sleeve and the clamping block respectively.

Preferably, the glass plate is a red glass plate.

Preferably, the top of the device box is fixedly connected with a plurality of locking blocks, and locking ports are formed in the locking blocks.

Has the advantages that:

1. Through the arrangement of the heat dissipation fan, the laser diode can be effectively dissipated, and meanwhile, when the glass plate needs to be cleaned and maintained, the clamping rod is firstly pulled out from the fixing plug, and then the glass plate is pulled out for cleaning and maintenance;

2. Meanwhile, the spring can elastically support the clamping rod to a certain extent, the sealing ring can prevent dust from entering the device box, the limiting sleeve can prevent the glass plate from falling off from the mounting hole, and the locking block can conveniently fix the device box.
