[0032] like Figure 5 As shown, a pair of support blocks 202 are fixed on the heat sink 201, and the support blocks 202 are used to support the fixed block 204 and the support plate 203.

[0034] like Figure 1 to Figure 2 As shown, a pair of heat sinks 201 are each provided with a sliding cavity 205, and the interior of the sliding cavity 205 is used to place an extrusion plate 206, a sliding plate 207 and a lifting spring 208.

[0035] like Figure 2 As shown, a pair of extrusion plates 206 are both fixed with sliding plates 207 , and the sliding plates 207 can be squeezed by the pushing block 303 , thereby driving the extrusion plates 206 to compress the lifting springs 208 , and the extrusion plates 206 can support the pushing block 303 .

[0036] like Figure 1 to Figure 2As shown, a lifting spring 208 is installed between a pair of extrusion plates 206 and the heat sink 201. The lifting spring 208 can be squeezed by the extrusion plate 206, and the lifting spring 208 can push the extrusion plate 206 to move through elastic force, thereby pushing the sliding plate 207 and the pushing block 303 to move.

[0037] like Figure 1 to Figure 2 As shown, a pair of extrusion plates 206 are both slidably connected to limit rods 209, and the limit rods 209 are fixedly connected to the heat sink 201. The limit rods 209 are used to support the extrusion plates 206 so that the extrusion plates 206 are not easily tilted during movement.

[0038] like Figures 1 to 3 As shown, the fixing mechanism 3 is installed on a pair of heat sinks 201, and the fixing mechanism 3 includes a pair of sliding blocks 301, and the sliding blocks 301 are used to support the clamping blocks 302 and can drive the clamping blocks 302 to move. The clamping blocks 302 are fixed on the sliding blocks 301, and the clamping blocks 302 can fix the pushing blocks 303, so as to fix the fixing blocks 204 and the fan body 1.

[0039] like Figures 1 to 3 As shown, a pair of fixed blocks 204 are both fixed with push blocks 303, and the push blocks 303 can be fixed by the clamping blocks 302, so that the fixed blocks 204 can be fixed on the support plate 203. A pair of heat sinks 201 are both slidably connected with lifting blocks 304, and pressing the lifting blocks 304 can drive a pair of connecting plates 305 to move, thereby driving the push rod 306 to move.

[0040] like Figures 1 to 3 As shown, a pair of connecting plates 305 are fixed on the lifting block 304, and the pair of connecting plates 305 are used to support the push rod 306, so that the push rod 306 can move with the lifting block 304. A push rod 306 is fixed between the pair of connecting plates 305, and the push rod 306 can slide inside the slide groove 307, so that the push rod 306 can drive the sliding block 301 to move during the movement. The pair of sliding blocks 301 are both opened with a slide groove 307 corresponding to the push rod 306, and the push rod 306 is placed inside the slide groove 307.

[0041] like Figure 4 As shown, a pair of lifting blocks 304 are each fixed with a plurality of protrusions 308 , which are used to support the lifting blocks 304 , and the protrusions 308 can be supported on the side walls of the grooves 309 , so that the protrusions 308 can constrain the moving trajectory of the lifting blocks 304 .

A fixing spring 310 is installed between the pair of sliding blocks 301 and the fan body 1, and the fixing spring 310 is used to push the sliding blocks 301 to move, thereby pushing the clamping block 302 to move.

[0043] When in use, align the pair of fixing blocks 204 on the fan body 1 with the pair of supporting plates 203 so that the fixing blocks 204 can be inserted into the supporting plates 203, and the supporting plates 203 can support the fixing blocks 204, thereby supporting the fan body 1;

[0044] The fixed block 204 can drive the push block 303 to squeeze the card block 302 during the movement, so that the card block 302 is not easy to block the push block 303 and the fixed block 204 from moving, and the card block 302 can drive the sliding block 301 to squeeze the fixed spring 310. The push block 303 can also drive the sliding plate 207 to move during the movement, so that the sliding plate 207 can drive the squeezing plate 206 to squeeze the lifting spring 208.

[0045] When the pushing block 303 moves to below the clamping block 302, the fixing spring 310 can push the clamping block 302 to move, thereby pushing the clamping block 302 to move, so that the clamping block 302 can fix the pushing block 303, thereby fixing the fixing block 204 and the fan body 1;

[0046] When the fan body 1 is disassembled, the pair of lifting blocks 304 are pressed, and the lifting blocks 304 can drive the pair of connecting plates 305 to move, thereby driving the push rod 306 to move, so that the push rod 306 can slide on the side wall of the slide groove 307, thereby pushing the sliding block 301 to move, so that the clamping block 302 no longer fixes the push block 303;

[0047] The force on the sliding plate 207 is reduced, so that the lifting spring 208 can push the extrusion plate 206 to move, thereby pushing the sliding plate 207, the pushing block 303 and the fixed block 204 to move, so that one end of the pushing block 303 moves above the blocking block 302, making it difficult for the blocking block 302 to fix the pushing block 303 again, pulling the fan body 1, and moving the fixed block 204 out from the support plate 203, so that the fan body 1 can be removed.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
