[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Depend on Figure 1 to Figure 6 As shown, the Uss base of the knitting machine of this embodiment includes a base 10, a sliding member 20, two thread clamps 30 and an elastic reset element.

[0026] The sliding member 20 is installed on the base 10 and can slide left and right relative to the base 10. The sliding member 20 is provided with a force-bearing portion 21 and two track grooves 22 extending in the left and right directions. The force-bearing portion 21 is used to receive external force to drive the sliding member 20 to slide left and right relative to the base 10. When the bridge moves back and forth laterally on the needle bed seat, the top rod on the bridge can contact with the force-bearing portion 21 to apply force to the force-bearing portion 21, thereby driving the sliding member 20 to slide left and right relative to the base 10.

[0027] The two thread clamps 30 are both mounted on the base 10, and the two thread clamps 30 are respectively located on the left and right sides of the base 10. Each thread clamp 30 is provided with a thread passing hole 31 for passing the yarn, a thread clamping mechanism for clamping or loosening the yarn, and a driving head 32 connected to the thread clamping mechanism to drive the thread clamping mechanism to move. The thread passing holes 31 on the two thread clamps 30 are coaxially arranged, and the two driving heads 32 are respectively located in the two track grooves 22.

[0028] When the two drive heads 32 are respectively located at the middle position of their respective track grooves 22, the two thread clamping mechanisms are in a state of clamping the yarn; when the two drive heads 32 are respectively located at the left and right ends of their respective track grooves 22, the two thread clamping mechanisms are in a state of loosening the yarn.

[0029] The elastic reset element is used to apply a reset force to the sliding member 20 after the sliding member 20 slides to the left or right, that is, the initial position of the sliding member 20 is in the middle of the base 10. When the sliding member 20 slides to the left or right, the elastic reset element can reset the sliding member 20 to the initial position.

[0030] The lower walls of the two track grooves 22 are both concave arc-shaped structures along the left and right directions, and the two drive heads 32 respectively abut against the lower walls of the two track grooves 22. In this way, when the sliding member 20 moves left and right, the lower wall of the track groove 22 applies an upward force to the drive head 32, so that the drive head 32 drives the wire clamping mechanism to operate.

[0031] The wire clamping mechanism includes a shell 36, a first clamping member 33, a spring 34 and a second clamping member 35. The shell 36 is installed on the base 10, and the wire hole 31 is set on the shell 36. The first clamping member 33 is slidable up and down in the shell 36. The upper part of the first clamping member 33 extends out of the top of the shell 36. The drive head 32 is connected to the upper part of the first clamping member 33. The first clamping member 33 can slide up and down relative to the shell 36. The spring 34 is used to apply downward force to the first clamping member 33. The spring 34 exerts a downward force on the first clamping member 33, and the first clamping member 34 is fixedly connected to the driving head 32, so that the driving head 32 can always be kept against the lower wall of the track groove 22 by the force of the spring 34. The second clamping member 35 is located below the first clamping member 33, and the gap between the second clamping member 35 and the first clamping member 33 is used to pass the yarn, so that the yarn can be clamped or released by the first clamping member 33 and the second clamping member 35.

[0032] An arc-shaped groove 331 is provided below the first clamping member 33, and the second clamping member 35 is cylindrical. The second clamping member 35 and the arc-shaped groove 331 are directly opposite to each other and fit each other. In this way, when the first clamping member 33 and the second clamping member 35 clamp the yarn, the second clamping member 35 is engaged in the arc-shaped groove 331 of the first clamping member 33, so that the first clamping member 33 and the second clamping member 35 clamp the yarn firmly.

[0033] An avoidance notch 332 is provided on the side wall of the first clamping member 33, and the spring 34 is located in the avoidance notch 332. The upper end of the spring 34 abuts against the upper inner wall of the shell 36, and the lower end of the spring 34 abuts against the bottom of the avoidance notch 332. In this way, the spring 34 is installed by providing the avoidance notch 332, so that the first clamping member 33 and the spring 34 are compactly arranged in the shell 36 to save space, thereby making the wire clamp 30 smaller in size.

[0034] A protective cover 37 made of a flexible material is sleeved in the thread-passing hole 31 of the housing 36, so that the friction force on the yarn when it moves in the thread-passing hole 31 can be reduced to avoid damage to the yarn.

[0035] The above description of the wire clamping mechanism is directed to the structure of a single wire clamping mechanism, and the structures of the wire clamping mechanisms in the two wire clamps in this embodiment are consistent.

[0036] The elastic reset element is an elastic metal strip 40. Two first positioning rods 11 spaced apart from each other are provided on the base 10. Two second positioning rods 23 spaced apart from each other are provided on the sliding member 20. The two first positioning rods 11 and the two second positioning rods 23 are symmetrically arranged about the same vertical axis. The two second positioning rods 23 are located above the two first positioning rods 11. The spacing between the two second positioning rods 23 is smaller than the spacing between the two first positioning rods 11. The elastic metal strip 40 is sequentially wound and fixed on the two first positioning rods 11. The two ends of the elastic metal strip 40 respectively abut against the opposite sides of the two second positioning rods 23. In this way, no matter whether the sliding member 20 slides to the left or to the right, the elastic metal strip 40 can reset the sliding member 20, so that the structure of the elastic reset element is simple.

[0037] The sliding member 20 is provided with a plurality of long slot holes 24 extending in the left and right directions, and a plurality of sliding posts 12 are fixedly provided on the base 10. The plurality of sliding posts 12 are slidably provided in the plurality of long slot holes 24, respectively. In this way, when the sliding member 20 slides left and right relative to the base 10, the movement is relatively stable.

[0038] When the Uss seat of this embodiment is used, the yarn passes through the thread holes 31 in the two thread clamps 30 in sequence. When the Uss seat is idle, refer to Figure 2 At this time, under the downward push of the spring 34 on the first clamping member 33, the first clamping member 33 and the second clamping member 35 in the two clamps 30 clamp the yarn; and when the Uss seat works normally, refer to Figure 3 At this time, the bridge of the knitting machine moves to the left, and the top rod on the bridge applies a leftward thrust to the force-bearing part 21 on the sliding member 20, thereby driving the sliding member 20 to move to the left. At this time, the two driving heads 32 move to the ends of the track grooves 22 along the lower walls of the two track grooves 22 respectively. Since the lower wall of the track groove 22 is a concave arc structure, the first clamping members 33 in the two thread clamps 30 move upward at this time, so that the first clamping members 33 and the second clamping members 35 in the two thread clamps 30 loosen the yarn. When the bridge of the knitting machine moves back to the right, the elastic metal strip 40 can make the sliding member 20 move to the right and reset.

[0039] The above is only an example of the preferred application of the utility model, but it cannot be understood as a limitation of the claims. The structure of the utility model can have other changes and is not limited to the above structure. In short, all changes made within the scope of protection of the independent claims of the utility model are within the scope of protection of the utility model.
