[0022] Referring to Figure 4 One side wall of one end of the assembly seat 3220 is provided with an assembly groove 3240, the outlet end of the guide air channel 3230 is communicated with the bottom of the assembly groove 3240, and one end of the clamping block 40 is inserted into the assembly groove 3240, and it should be noted that the end of the clamping block 40 is matched with the assembly groove 3240, so that one end of the clamping block 40 is inserted into the assembly groove 3240, further, the bottom of the assembly groove 3240 is embedded with a magnetic block 3250, the magnetic block 3250 is provided with a through hole 3260, one end of the clamping block 40 is adsorbed on the magnetic block 3250, the through hole 3260 is communicated with the guide air channel 3230 and the heat dissipation channel 50, and specifically, the end of the clamping block 40 is a metal block which can be adsorbed with the magnetic block 3250, so that the end of the clamping block 40 is inserted into the assembly groove 3240 and adsorbed on the magnetic block 3250, so as to fix the clamping block 40.

[0023] Referring to Figure 2 The clamping assembly 30 further comprises a double-headed screw 330 which is rotatably connected with the side wall of the box body 20, two inner threaded blocks 340 are threadedly arranged on the double-headed screw 330, and the two inner threaded blocks 340 are fixedly connected with the two moving blocks 310, when arranged, one end of the double-headed screw 330 is rotatably connected with one end of the side wall of the box body 20, and the cylindrical part of the double-headed screw 330 rotatably penetrates the other end of the side wall of the box body 20, and a handle is fixedly installed on the other end of the side wall, further, two through holes are arranged on the top of the box body 20, and the two inner threaded blocks 340 pass through the two through holes respectively, so as to rotate the double-headed screw 330, drive the two inner threaded blocks 340 to move, and the through holes can limit the inner threaded blocks 340.

The fan 620 sucks the external air into the installation pipe 610, so that the air in the installation pipe 610 is shunted into the four soft tubes 630, and then flows into the four air guide pipes 3210.

[0026] When the laser spot welding machine works: the workpiece to be welded is placed on the box body 20, the double-headed screw rod 330 is rotated to drive the two inner threaded blocks 340 to move towards each other, thereby driving the two moving blocks 310 to move towards each other, so as to drive the two clamping blocks 40 to move towards each other and clamp and fix the workpiece. The clamping block 40 is continuously used to cause the temperature to rise. At this time, the fan 620 operates to suck the external air into the installation pipe 610. The installation pipe 610 delivers the air to the four soft tubes 630, so that the air flows into the four air guide pipes 3210. The air then enters the heat dissipation channel 50 through the air guide channel 3230 and the through hole 3260, so as to achieve the purpose of heat dissipation of the clamping block 40.
