The embodiment comprises a triangle motherboard 9 and a double-layer motor 1, wherein the double-layer motor is provided with two coaxial motor shafts in the same direction, a first motor shaft 61 is a hollow shaft, a second motor shaft 62 penetrates through the first motor shaft and extends out of the first motor shaft, and the two motor shafts are in clearance fit and can independently rotate without affecting each other; two independent coil windings are arranged in the double-layer motor, and two motor shafts are respectively and independently controlled; the sheave 3 is fixed to the first motor shaft 61, and the cam 4 is fixed to the second motor shaft 62.
See fig. 3-5. The motor 1 is arranged on the motor fixing plate 2, the motor shaft is connected with the grooved pulley 3, and the grooved pulley 3 is driven to perform reciprocating rotary motion. The upper surface of the sheave 3 has an arcuate limit groove 39 and the circumference has an elongated groove 37, in this embodiment the elongated groove 37 extends through 360 0 Is a wavy long groove with two high points and two low points, and smoothly transits to form the long groove 37.
The present embodiment further includes a triangle master 9, a base 8, a mount 10, and a connection plate 47, the base 8 is fixed on the triangle master 9, and a guide post 49 is provided on the base, so that the guide post 49 is indirectly fixed on the triangle master 9. The middle part of the connecting plate 47 is provided with a through hole which is sleeved on the guide post 49 and can move up and down along the guide post 49; the front end of the connecting plate 47 is provided with a roller 63, and the roller 63 is clamped into the wavy long groove 37 of the grooved pulley and can move in the wavy long groove; the rear end of the link plate 47 is connected to the mountain guide connecting post 56 by a pin 48.
The triangle motherboard 9 is provided with a Zhongshan guide block (not shown in the figure) and a needle turning guide block 60, wherein the Zhongshan guide block and the needle turning guide block are respectively provided with a Zhongshan guide block connecting column 56 and a needle turning guide block connecting column 58, and the triangle motherboard further comprises a connecting rod 55, two ends of the connecting rod 55 are respectively connected with the Zhongshan guide block connecting column 56 and the needle turning guide block connecting column 58 in a rotating way, the middle part of the connecting rod is provided with a rotating shaft 57, and the connecting rod 55 can rotate around the rotating shaft 57; the mounting base 10 is fixed on the triangle motherboard and is provided with two through holes perpendicular to the motherboard for two connecting columns to pass through; the mounting base 10 also has a hole parallel to the motherboard for setting the spindle 57 of the link. The needle guide block 60 is also provided with two compression springs 59 for eliminating the movement gap of the connecting rod 55. Through the design of the mounting seat, the zhongshan guide block, the needle turning guide block, the connecting column, the connecting rod and the like become a relatively independent and closed assembly.
The middle guide block connecting post 56 passes through the through hole of the mounting seat 10 and then is connected with the rear end of the connecting plate 47 through the pin shaft 48. The middle section of the pin 48 is spindle-shaped, i.e. the middle is thicker and the two ends are thinner, which can be understood as a part of a sphere, so that the pin is always in single-point or single-line contact with the connecting post 56 of the Zhongshan guide block.
The operation of this part is that the double-layer motor 1 drives the grooved pulley 3 to rotate through the first motor shaft 61 thereof, so that the roller 63 clamped in the long groove 37 moves upwards or downwards, thereby driving the connecting plate 47 to move up and down along the guide post 49 as a whole, and the rear end of the connecting plate drives the zhongshan guide block connecting post 56 to move upwards or downwards through the pin shaft 48, and the connecting rod 55 plays a role of a seesaw, so that the needle turning guide block connecting post 58 moves reversely.
It is noted that the mountain guide connecting post 56 passes through the through hole of the mount 10 and needs to move up and down in the through hole, where it is easily stuck when worn or improperly assembled. Through the spindle-shaped design of the pin shaft, the condition that only the center point of the connecting column of the Zhongshan guide block is stressed is guaranteed, and the stress state is more reasonable, so that the machining precision and the assembly precision can be correspondingly reduced.
An inductor 50 is arranged above the motor fixing plate 2, and a limiting pin 52 is fixed below the motor fixing plate. The inductor 50 can timely control the forward rotation or the reverse rotation of the motor according to the phase of the grooved pulley 3. The stopper pin 52 is inserted into the stopper groove 39 so that the rotation angle of the sheave 3 is limited within the angle range of the stopper groove.
See fig. 6-11. This section of the embodiment focuses on describing a two-stage scale control system, and those skilled in the art will appreciate that the two-stage scale control system is side-to-side symmetrical, and even though only one side is shown and described, the other side has symmetrical components.

The tail end of the movable triangle 13 is provided with two pin shafts 19 and 20 which are matched with the cam 4, wherein the pin shaft 19 is abutted against the outer track surface of the cam 4, and the pin shaft 20 is abutted against the inner track surface of the cam 4.
The movable triangle is provided with two tension springs 15, one end of each tension spring is fixed on the frame, and the other end of each tension spring is fixed on the movable triangle, so that the clearance of the movable triangle during the movement can be counteracted; the upper and lower positions of the movable triangle 13 are limited by the movable pressing plate 14 and the pressing plate 16, and the left and right positions of the movable triangle are adjusted by the four eccentric adjustable bearings 12a, 12b, 12c and 12d respectively, so that the left and right consistency of the movable triangle is better.
The stitch transmission part comprises a first stitch swing rod 21 and a second stitch swing rod 22, the first stitch swing rod 21 is rotatably arranged on a stitch connecting block 26 through a rotation center pin 35, one end of the first stitch swing rod is provided with a first bearing 25, the first bearing 25 is provided with an eccentric adjustable bearing pin 31, and the bearing pin 31 extends into a movable triangular groove 131; a second bearing 36 is arranged below the first stitch swing rod, a bearing pin 38 is arranged on the second bearing 36, and the bearing pin 38 extends into a waist groove of the two-section stitch connecting block 26. The second stitch swing rod 22 is rotatably arranged on the first stitch swing rod 21 through a center line pin 33, and a third bearing 32 is arranged above the second stitch swing rod; the side walls of the first stitch swing rod and the second stitch swing rod are provided with 23 pressure springs, so that the first bearing 25 and the third bearing 32 have relative movement trend, and are respectively abutted against the outer side wall of the movable triangle 13 and the inner side wall of the triangle groove 131 with radian.

The working process of the part is as follows:
when the double-layer motor 1 works, the second motor shaft 62 drives the cam 4 to rotate, and the movable triangle 13 is driven to reciprocate by pushing and pulling the pin shafts 19 and 20, so that the bearing pin 32 in the movable triangle groove 131 drives the transmission mechanism, and the two-section mesh 30 acts. Fig. 10a and 11a show a state in operation in which the cam 4 is ejected outwards, eventually resulting in delamination of the two-stage mesh 30 from the main mesh 29; fig. 10b and 11b show another state in which the cam 4 is rotated to another phase, pulling the pin inwards, eventually resulting in a gradual reduction in the layering distance of the two-stage mesh 30 from the main mesh 29 until coincidence is achieved.
It should be noted that, in this embodiment, only the relative relationship between the two-stage degree and the main degree, and the consistency of the two-stage degree are described. The motion of the mesh itself in the mesh slots 91, 92 is driven by the main mesh driving members 44, 45, etc., as in the prior art, and need not be described here.
