In the middle of the upper end of the limiting mechanism, a chip body is movably inserted. At the front and rear of the upper end of the substrate, two inserting rods are fixedly connected respectively. At the left and right of the upper end of the substrate, a number of pins are fixedly connected at equal distances. At the upper left and upper right of the substrate, support rods are fixedly connected respectively. At the lower end of the substrate, a positioning mechanism is movably inserted. The outer surfaces of the four inserting rods are jointly movably inserted with an upper cover mechanism. The lower end of the upper cover mechanism is in close contact with the substrate but not connected. At the upper end of the upper cover mechanism, a heat dissipation shell is fixedly connected. A number of the pins are all connected to the chip body through a number of metal wires.
[0007] Preferably, the limiting mechanism includes a connecting seat. In the middle of the upper end of the connecting seat, a through groove is opened. At the front and rear of the upper end of the connecting seat, two connecting grooves are opened respectively, and positioning blocks are fixedly inserted in the four connecting grooves. At the left and right of the upper end of the connecting seat, grooves are opened. The connecting seat is fixedly connected to the substrate.

[0032] The limiting mechanism 2 includes a connecting seat 21. A through groove 22 is formed in the middle of the upper end of the connecting seat 21. By providing the through groove 22, it is convenient to install the chip body 3. Two connecting grooves 23 are formed in both the front part and the rear part of the upper end of the connecting seat 21, and positioning blocks 24 are fixedly inserted and connected in the four connecting grooves 23. Grooves 25 are formed in both the left part and the right part of the upper end of the connecting seat 21. By providing the grooves 25, it is convenient for the chip body 3 to be connected to the pins 5. The connecting seat 21 is fixedly connected to the substrate 1; The upper cover mechanism 8 includes a housing 81. A fixing groove 82 is formed in the middle of the lower end of the housing 81. A thermal interface plate 85 is fixedly connected to the middle of the upper groove wall in the fixing groove 82.

During use, the heat of the chip body 3 is introduced to the upper end of the thermal interface plate 85 and then introduced to the outer shell 81 by the thermal interface plate 85, so that the chip body 3 can dissipate heat quickly. A plurality of connecting columns 73 are all interspersed with the circuit board, so that the positioning mechanism 7 is installed on the circuit board. The lower parts of a plurality of pins 5 are interspersed with a plurality of through columns 72.
