[0044] Furthermore, since the pushing mechanism 5 and the pressing plate 10 are provided with two groups, when the delivery box 8 is moved to the right until all the spring pins are put in, the bidirectional motor 9 can be driven in the reverse direction to work, and the spring pins are put in the right position of the delivery box 8, so as to realize the selective feeding on the left and right sides, and the delivery box 8 is reset without the bidirectional motor 9 working;

[0045] Furthermore, a threading mechanism 4 is provided on the first mounting plate 201, and the threading mechanism 4 is connected via a transmission mechanism 6, the threading mechanism 4 includes a first synchronous wheel 401, a second synchronous wheel 402, a first synchronous belt 403 and a threading sleeve 404, the transmission mechanism 6 includes a third synchronous wheel 601, a second synchronous belt 602, a fourth synchronous wheel 603, a first bevel gear 604 and a second bevel gear 605, etc. Through the above-mentioned structural arrangement, when the bidirectional motor 9 is working, the third synchronous wheel 601 can be rotated, the fourth synchronous wheel 603 can be rotated under the action of the second synchronous belt 602, and then the fourth synchronous wheel 603 can be moved, the second synchronous wheel 402 can be rotated under the action of the first bevel gear 604 and the second bevel gear 605, and the first synchronous belt 403 drives the threading sleeve 404 The movement requires the copper wire of the electric welding spring needle to be straightened and tightly threaded into the threading sleeve 404, and the inner wall of the threading sleeve 404 can be fixed with a rubber layer. Each time the round table 3 rotates 90 degrees, the threading sleeve 404 moves to correspond to its buckle groove 301, thereby realizing the automatic welding needle operation of the copper wire, and synchronously driving the arranged wire to move, so that it forms a one-to-one with the spring needle for welding, without manual close contact with the welding needle, which is safer and more accurate. The triangular pad 15 arranged on the first mounting plate 201 serves to lift the copper wire after the welding point, and smoothly moves the copper wire after the welding point to fit the outer wall of the first mounting plate 201 to form a bend, which is conducive to quickly testing whether the welding point is firm.
