[0022] In this embodiment, firstly, the connecting rod 4 is inserted into the interior of the mounting block 3, and then the screw 6 is tightened inside the mounting block 3 and inserted into the socket 5. At this time, the connecting rod 4 will be installed inside the mounting block 3 by the screw 6, and the connecting ring 7 can be installed. By setting the crossbar 8, the cooling component 2 can be surrounded and blocked, thus playing a protective role.

[0023] In a further preferred embodiment of this utility model, the cooling component 2 includes: a first mounting ring 201 attached to the surface of the pipe 1, a second mounting ring 202 attached to the side of the first mounting ring 201, a locking block 203 slidably connected inside the first mounting ring 201 and the second mounting ring 202, a connecting plate 204 fixedly connected to the top of the locking block 203, a connecting plate 205 fixedly connected to the side of the first mounting ring 201 and the second mounting ring 202, a screw 206 threadedly connected inside the connecting plate 205, a stop block 207 rotatably connected to one end of the screw 206, a slide rod 208 fixedly connected to one end of the stop block 207 and slidably connected to the connecting plate 205, a heat sink 209 fixedly connected inside the first mounting ring 201 and the second mounting ring 202, a heat dissipation end 210 fixedly connected to the surface of the heat sink 209, and a miniature fan 211 fixedly connected to one side of the first mounting ring 201 and the second mounting ring 202.

[0032] In this embodiment, rotating the screw 206, under the limit of the slide bar 208, will control the stop 207 to slide forward and move to the position where it fits against the locking block 203, so that it fixes the locking block 203 inside the mounting block 3.

[0033] In a further preferred embodiment of this utility model, the mounting block 3 is provided with a connecting hole that matches the size of the connecting rod 4, and the screw 6 passes through the mounting block 3 and is inserted into the insertion hole 5.

[0034] In this embodiment, the screw 6 is tightened inside the mounting block 3 and inserted into the socket 5. At this time, the connecting rod 4 will be installed inside the mounting block 3 by the screw 6.

[0038] In this embodiment, by setting the anti-radiation coating 10, the overall cooling structure can be cooled.

[0039] In a further preferred embodiment of the present invention, several groups of through holes 9 are arranged in a straight line at equal intervals on the surfaces of the first mounting ring 201 and the second mounting ring 202.

[0040] In this embodiment, by providing through holes 9, heat can be dissipated more easily.
