When one cross bar 310 rotates, the other cross bar 310 is rotated in the opposite direction through the two flat gears 2 320, and then the two rotating rods 240 are rotated in the opposite direction at the same time through the bevel gears 1 330 and the bevel gears 2 340. The rotating rotating rods 240 drive the lifting plate 210 to rise and fall along the rod body of the guide rod 200 through the flat gears 1 260 and the rack 250, so that the plug block 220 is inserted into or pulled out of the sockets 1 130 and the sockets 2 140.

[0032] Furthermore, a protective shell 350 is disposed on the front side wall of the base 100. The inner cavity of the protective shell 350 is hollow and accommodates the driving components to prevent the components from being exposed to the outside.

[0033] Furthermore, one end of a cross bar 310 extends through the side wall of the protective shell 350 , and a turntable 360 ​​is provided at the end, and the turntable 360 ​​is used to conveniently drive the cross bar 310 to rotate.

[0034] Furthermore, a positioning groove 150 is provided on the top of the base 100 for the mounting plate 120 to be inserted vertically. When the mounting plate 120 is located in the positioning groove 150, the socket 1 130 and the socket 2 140 are aligned. By positioning the mounting plate 120, the socket 1 130 can be more easily aligned with the socket 2 140, so that the vertical insertion of the plug block 220 is convenient.

[0035] During specific use, the heat sink body 110 can be quickly disassembled without any tools. After the turntable 360 ​​drives one cross bar 310 to rotate, the two flat gears 320 are used to make the other cross bar 310 rotate in the opposite direction, and then the bevel gear 1 330 and the bevel gear 2 340 are used to make the two rotating rods 240 rotate in the opposite direction at the same time. The rotating rotating rod 240 drives the lifting plate 210 to rise and fall along the rod body of the guide rod 200 through the flat gear 1 260 and the rack 250, so that the plug block 220 is inserted into or pulled out of the socket 1 130 and the socket 2 140, which facilitates the disassembly and assembly of the heat sink body 110.

[0036] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention.
