[0100] Specifically, combined Figure 7 As shown, the fixed connection structure 11 includes a hook 20 , which is connected to the connecting arm 8 as a whole.

[0101] The hook 20 integrally connected to the connecting arm 8 at the upper end of the connecting arm 8 is used for cooperation and connection with the transfer plate body, which is convenient for installation of the connecting arm 8, and the connecting arm 8 is firmly fixed and convenient for assembly and disassembly.

[0102] Specifically, combined Figure 7 As shown, a base plate 21 is provided between the hook 20 and the connecting arm 8 .

[0103] There are clearance grooves 23 between the upper ends of the strip spring 19 and the base plate 21 on both sides, and an arc-shaped reinforcement portion 24 is provided between the clearance grooves 23 and the strip spring 19. Through the above structure, the base plate 21 and the strip spring 19 form a flexible hinge structure.

[0104] The substrate 21 between the hook 20 and the connecting arm 8 is used to cooperate and connect with the substrate card slot 46 on the transfer plate body. The length of the strip spring 19 is lengthened, which can effectively improve the fatigue toughness. The give way groove 23 plays a role of giving way when the strip spring 19 swings, and the arc-shaped reinforcement part 24 plays the role of strengthening the structure.

[0105] Specifically, combined Figure 7 and Figure 8 As shown, the detachable fixing structure 13 includes a card slot 29 arranged near the hook tongue 2 of the horizontal needle body 1, and a card body 30 that can cooperate with the card slot 29 is provided on the lower end of the connecting arm 8.

The card body 30 on the lower end of the connecting arm 8 can be snapped into the card slot 29 on the horizontal needle body 1 to achieve a mating connection, making the connection between the connecting arm 8 and the horizontal needle body 1 more stable and convenient to assemble and disassemble. The anti-detachment structure 31 between the card slot 29 and the card body 30 can prevent the card body 30 at the lower end of the connecting arm 8 from detaching from the card slot 29 when the connecting arm 8 swings, thereby strengthening the connection between the connecting arm 8 and the horizontal needle body 1.

[0107] Specifically, combined Figure 7 and Figure 8 As shown, the anti-separation structure 31 includes a necked portion 32 provided on the outer end of the slot 29 , and the width of the necked portion 32 is smaller than the width of the slot 29 .

[0108] Arc chamfers 33 are provided on both sides of the outer end of the necked portion 32. The arc chamfers 33 can effectively prevent the strip spring 19 from being damaged during the deformation process.

[0109] The constricted portion 32 on the outer end of the slot 29 can prevent the card body 30 at the lower end of the connecting arm 8 from detaching from the slot 29 when the connecting arm 8 swings, thereby reinforcing the connection between the connecting arm 8 and the horizontal needle body 1.

[0110] Preferably, combined Figure 7 As shown, the card slot 29 passes through both sides of the horizontal needle body 1 , and a fixing piece is provided between the card body 30 and the horizontal needle body 1 to prevent the card body 30 from escaping from the card slot 29 on both sides of the horizontal needle body 1 .

[0111] Specifically, combined Figure 11 As shown, the L-shaped rocker arm 4 is hingedly connected to the transfer disc body through a hinged connector arranged in the rocker arm hinge hole 6, and the lower end of the L-shaped rocker arm 4 is hinged on the horizontal needle body 1 through the rear hinge shaft 34. The base plate 21 at the upper end of the strip spring 19 and the hook 20 are cooperatively connected with the transfer disc body, and the card body 30 at the lower end of the strip spring 19 is embedded in the card slot 29, and the outer side of the hook 20 is fixed by a clamp 45.

[0112] In this embodiment, the substrate 21, the strip spring 19 and the card body 30 are made of metal materials, and the metal material includes any one of stainless steel, copper, titanium and the like.

[0113] During the radial movement of the horizontal needle body 1, the lower end of the strip spring 19 above the card body 30 swings, and the upper end of the strip spring 19 below the base plate 21 also swings to limit the running direction of the horizontal needle body.
