The driving device is an electromagnet.
The combined through groove consists of a longitudinal groove and a transverse groove, wherein the first part of the combined through groove is the longitudinal groove used for a transmission mechanism; the second part of the combined through groove is a transverse groove used for the protruding end of the two-section press leg.
The electromagnets are in a parallel form, the three electromagnets in the middle drive the three press legs arranged on the mounting seat, and the two electromagnets on the two sides drive the two press legs arranged on the upper shaft; the left two-section pressing leg and the right two-section pressing leg which are arranged on the upper shaft are matched with the electromagnet through a splayed transmission mechanism.
The left second-section pressing leg and the right second-section pressing leg are respectively arranged on the upper shaft through torsion springs; two sides of the splayed transmission mechanism are respectively and rotatably arranged on the lower shaft, the upper end of the splayed transmission mechanism is abutted against the protruding ends of the left and right two-section pressing legs, the direction of the abutting force is opposite to the elastic direction of the torsion spring, and the lower end of the splayed transmission mechanism is matched with the movable core of the electromagnet and the pressure spring.

It can be seen that the five press legs are divided into two layers, the upper layer is two, the lower layer is three, and the five press legs are symmetrical left and right.
Since the leg presses are left-right symmetrical, only one side may be referred to in the drawings and the following description, and the other side will be understood by those skilled in the art.
This embodiment has five electromagnets 181, 182, 183, 184, 185 arranged in sequence. The electromagnet 181 corresponds to the left second-stage press leg 6, the electromagnet 182 corresponds to the left needle press leg 10, the electromagnet 183 corresponds to the eye press leg 8, the electromagnet 184 corresponds to the right needle press leg 9, and the electromagnet 185 corresponds to the right second-stage press leg 7.

The transmission mechanism of the electromagnet 182 comprises a base 2 and a first connecting piece 191, the lower part of the first connecting piece 191 is pivoted on the base through a torsion spring 5, the upper part of the first connecting piece is matched with a movable core of the electromagnet 182, and when the movable core extends out, the first connecting piece 191 is pressed against and driven to rotate; the lower shaft 25 is pivoted with a third connecting piece 211, and the upper end of the third connecting piece 211 extends into the first part 331 of the combined through groove of the left connecting pin pressing leg 10 to drive the movement of the third connecting piece; the second link 241 is rotatably coupled to an upper end of the first link 191 and a lower end of the third link 211, respectively.
When the electromagnet 182 acts, the movable core extends out to push against the first connecting piece 191 to rotate on the base, so that the third connecting piece 21 is driven to rotate around the lower shaft 25 through the second connecting piece 241, and the upper end of the third connecting piece drives the left connecting pin press leg 10 to move; when the moving core of the electromagnet retracts, the torsion spring 5 drives the first connecting piece 191 to rotate reversely, so that the components move reversely, and the reciprocating motion is realized, so that the left connecting needle pressing leg 10 repeatedly extends and retracts.
For the electromagnet 183 and the eye presser leg 8, and the electromagnet 184 and the right connector presser leg 9, see the above description.
The rear of the left second leg 6 has a projecting end 61 which extends downwardly through the second portion 332 of the combined channel, the projecting end 61 being movable therein due to the elongated channel 332. The transmission mechanism between the left two-section leg pressing 6 and the electromagnet 181 is a splayed one edge 22, and the transmission mechanism between the right two-section leg pressing 7 and the electromagnet 185 is a splayed other edge 27.
