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

Detailed Description
See the drawings. The embodiment has five pressing legs, namely a left two-section pressing leg 6, a right two-section pressing leg 7, a eye pressing leg 8, a right needle pressing leg 9 and a left needle pressing leg 10, wherein the left two-section pressing leg 6 and the right two-section pressing leg 7 are rotatably arranged on an upper shaft 13 through a torsion spring 12, and the left needle pressing leg 10, the eye pressing leg 8 and the right needle pressing leg 9 are respectively and slidably arranged in grooves 281, 282 and 283 of an installation seat 28. It can be seen that the five press legs are divided into two layers, the upper layer is two and the lower layer is three, and the press legs are bilaterally symmetrical.
Since the leg is left-right symmetric, only one side of the leg may be referred to in the drawings and the following description, and those skilled in the art will understand the case of the other side.
The present embodiment has five electromagnets 181, 182, 183, 184, 185 arranged in this order. Wherein electromagnet 181 corresponds to left two-stage press leg 6, electromagnet 182 corresponds to left needle press leg 10, electromagnet 183 corresponds to hanger press leg 8, electromagnet 184 corresponds to right needle press leg 9, and electromagnet 185 corresponds to right two-stage press leg 7.
The eye pressing leg 8, the right needle pressing leg 9 and the left needle pressing leg 10 are all provided with through grooves, wherein the eye pressing leg 8 is a square through groove 331, and the right needle pressing leg 9 and the left needle pressing leg 10 are T-shaped combined through grooves formed by the square through groove 331 and the long through groove 332.
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 the moving core of the electromagnet 182, and when the moving core stretches out, the first connecting piece 191 is propped 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 stretches into the first part 331 of the combined through groove of the left needle pressing leg 10 to drive the third connecting piece to move; the second link 241 is rotatably coupled to the upper end of the first link 191 and the lower end of the third link 211, respectively.
When the electromagnet 182 acts, the movable core extends out and props against the first connecting piece 191 to rotate on the base, so that the second connecting piece 241 drives the third connecting piece 21 to rotate around the lower shaft 25, and the upper end of the third connecting piece drives the left needle pressing leg 10 to move; when the moving core of the electromagnet is retracted, the torsion spring 5 drives the first connector 191 to reversely rotate, so that the aforementioned parts reversely move, and thus, the left needle pressing leg 10 repeatedly stretches and contracts.
For electromagnet 183 and eye leg 8, and electromagnet 184 and right needle leg 9, see the description above.
The rear part of the left leg pressing 6 has a protruding end 61 extending downwardly through the second part 332 of the combined channel, in which the protruding end 61 is movable due to the elongated channel 332. The transmission mechanism between the left two-stage pressing leg 6 and the electromagnet 181 is one side 22 of the splayed shape, and the transmission mechanism between the right two-stage pressing leg 7 and the electromagnet 185 is the other side 27 of the splayed shape. The transmission mechanism 22 is pivoted on the lower shaft 25, the upper end of the transmission mechanism is abutted against the protruding end 61 of the left two-section pressing leg 6, and the lower end of the transmission mechanism is matched with the moving core of the electromagnet 181 and the pressure spring 4.
When the electromagnet 181 operates, the movable core extends out, the compression spring 4 contracts, the transmission mechanism 22 rotates around the lower shaft 25, the upper end of the transmission mechanism contacts with the protruding end of the left two-section pressing leg 6, and the protruding end 61 can move in the long through groove 332, so that the left two-section pressing leg 6 swings around the upper shaft 13. When the moving core of the electromagnet is retracted, the pressure spring 4 is ejected to push the transmission mechanism 22 to reversely rotate, the upper end of the transmission mechanism does not apply pressure to the protruding end 61 of the left second-section pressure leg 6 any more, and therefore the elasticity of the torsion spring 12 pushes the left second-section pressure leg 6 to reversely swing around the upper shaft 13.
