[0035] When the laser body 15 is in the first shell 1 and inside the first shell 1, at this time the emitting end of the laser body 15 extends from the inside of the reserved hole 14 to the outside of the first shell 1, and the wire of the laser body 15 extends to the outside of the first shell 1 and the external equipment through the wire hole 13 and is connected with each other, in the process of using the laser body 15, the part of the laser body 15 located inside the first shell 1 will generate a large amount of heat, the heat generated by the laser body 15 will be conducted to the inside of the first shell 1 through the inside of the first shell 1, at this time the heat in the inside of the first shell 1 will be transmitted to the inside of the heat conduction pipe 5 in the inside of the mounting layer 3, the heat in the inside of the first shell 1 will be absorbed through the inside of the heat conduction pipe 5, and then the laser body 15 will be cooled, because the heat conduction pipe 5 is distributed in a spiral shape in the inside of the mounting layer 3, so that the area of the heat conduction pipe 5 in contact with the first shell 1 is increased, and the efficiency of cooling the first shell 1 is improved;
