the spring block is fixed at one side of the upper end surface of the lower supporting block, which is close to the top block, through an inner hexagon screw and a spring, and the spring is sleeved on the threaded end of the inner hexagon screw and penetrates through the spring block;

Two slotted holes are formed in the position, corresponding to the bottom end of the elastic pressing block, of one side of the upper end face of the lower supporting block in parallel, and a PCB placing groove is formed in the other side of the upper end face of the lower supporting block.

As a further technical scheme of the utility model, a PCB is placed in the PCB placement groove;

and a contact pin is inserted into the slot hole, and one end of the contact pin is horizontally arranged on the upper surface of the PCB.

As a further technical scheme of the utility model, two threaded holes are formed in the upper end face of the lower support block, corresponding to the inner hexagon screws, and one end of each inner hexagon screw penetrates through the corresponding elastic pressing block and is screwed into each threaded hole.

The utility model provides a spring type welding tool structure, which is compared with the prior art, has the following structure

The beneficial effects are that:

according to the spring type welding tool structure, through the cooperation of the ejector block, the lower supporting block, the PCB placement groove, the spring and the socket head cap screw, the height between the PCB and the contact pin can be fixed, the PCB and the contact pin can not be inclined during welding, the bushing phenomenon can not occur, the problem that welding errors occur easily in a traditional mode that the PCB is clamped by the clamp to weld is solved, the unqualified welding product is caused, and the reliability and the qualification rate of the product are greatly improved.
