It should be noted that:

the movement positions of the jack 22 are set to: as shown in fig. 12, the extreme position of the movement of the jack 22 toward the extensible member 341 is a position that extends into the through hole 332 and is flush with the side wall of the guide groove 333.

The relationship between the through hole 332 and the extensible member 341 in the guide member 33 is:

when the moving member 31 moves to the first position, the through hole 332 of the guide member 33 corresponds to the head of the extensible member 341, which enables the head of the extensible member 341 to extend into the through hole 332, and when the moving member 31 moves to the second position, the head of the extensible member 341 is misaligned with the through hole 332 of the guide member 33.

The following describes the process of assembling the motherboard 100 and the heat dissipation module 200 by using the above tooling:

first, the main board 100 is placed on the working platform 10, and one side of the main board 100 extends into the positioning groove 41 of the positioning block 40.

Then, an external force is applied to the moving part 31 toward the first end thereof (e.g., the hook 311 of the moving part 31 is pushed by a human hand), as shown in fig. 2, 6 and 14, when the moving part 31 is stopped by the end of the guide slot 333, the moving part 31 moves to the first position, at which the hook 311 limits the other side of the main board 100 to perform final positioning on the main board 100 by cooperating with the positioning block 40; meanwhile, the head of the telescopic member 341 of each telescopic mechanism is opposite to the through hole 332 of the guide groove 333, and under the action of the second elastic member 342, as shown in fig. 6 to 8, the head of the telescopic member 341 extends into the through hole 332, and at this time, after the external force is removed, the reset of the moving member 31 is limited because the head of the telescopic member 341 extends into the through hole 332 (that is, the telescopic member 341 moves to its first position by being pushed by the second elastic member 342), so that the moving member 31 is kept at the first position.

As shown in fig. 6 to 8, the process of the retractable member 341 extending into the through hole 332 is also the process of the retractable member 341 pushing against the top rod 22 of the trigger mechanism 20, the top rod 22 is pushed by the retractable member 341 and drives the plug 21 to move upwards via the connecting rod 24 to protrude out of the working platform 10, and further extends into the threaded hole 101 of the main board 100, that is, the plug 21 moves to the first position, and the state of the trigger mechanism 20 at this time is referred to as the first state.

Then, as shown in fig. 9, the heat dissipation module 200 is mounted on the motherboard 100, and all the mounting holes are aligned with the plurality of holes on the motherboard 100, as shown in fig. 10 to 12, and then the screws 300 are sequentially inserted through all the mounting holes by a screwdriver and screwed into the threaded holes 101 of the motherboard 100; after each screw 300 is screwed into position, the lower end of the screw 300 pushes the plug 21 downward to move the plug 21 downward to the second position, at this time, the plug 21 drives the top rod 22 to push the telescopic member 341 extending into the through hole 332 via the connecting rod 24, so that the telescopic member 341 exits from the through hole 332 (the state of the trigger mechanism 20 at this time is referred to as the second state), and the trigger mechanism 20 and the corresponding telescopic mechanism release the restriction on the moving member 31, however, if other threads are not screwed into other threaded holes 101, the trigger mechanism 20 and the corresponding telescopic mechanism of the threaded hole 101 still restrict the moving member 31. Thus, the moving member 31 is released from the restriction only when all the screws 300 are inserted into the corresponding screw holes 101.

After all the screws 300 are screwed into the threaded holes 101, all the trigger mechanisms 20 are switched to the second state, and the restriction on the moving member 31 is completely released, at this time, under the pushing of the first elastic member 32, as shown in fig. 15, the moving member 31 moves from the first position to the second position; thus, when the operator or the device finds that the moving part 31 has a reset motion moving from the first position to the second position, it indicates that all the screw holes 101 are screwed with the screws 300, and further, the operator or the device is prompted that the heat dissipation module 200 and the motherboard 100 are assembled. Meanwhile, as the moving part 31 moves from the first position to the second position, the hook 311 on the moving part 31 releases the limitation on the motherboard 100, so that an operator or equipment can take the motherboard 100 with the heat dissipation module 200 mounted thereon off the working platform 10.
