[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6, including a bottom plate 1, on both sides of the surface of the bottom plate 1, a first support plate 2 and a second support plate 3 are respectively fixed. The first support plate 2 and the second support plate 3 are symmetrically arranged. Activity slots are opened on the side surfaces corresponding to the positions of the sliders of the guide rail 4. The movable blocks at the ends of the guide rail 4 are installed in the activity slots, so that the guide rail 4 can move up and down along the activity slots. The guide rail 4 is installed above the bottom plate 1. Sliders are fixed on both sides of the guide rail 4, and a groove is opened at the bottom of the guide rail 4; a track frame 5 is sleeved on the outer surface of the guide rail 4, and the bottom is not closed. A placement groove is opened at the top of the track frame 5 for placing silk threads. A rotatable pressing rod is installed on the side of the placement groove. The top of the silk thread in the placement groove is restricted by the pressing rod to prevent the silk thread from deviating out of the placement groove during the knitting process. A groove is opened at the position corresponding to the pressing rod, and the groove is padded with elastic rubber. After the pressing rod restricts the silk thread, the bottom of the pressing rod is pressed into the groove, so that the groove catches the pressing rod, thereby restricting the movement of the pressing rod and ensuring the limiting effect of the silk thread. And the track frame 5 can move on the surface in contact with the guide rail 4, and the silk thread can move with the track frame 5; limiting holes 6 are opened on both sides of the guide rail 4 and are arranged linearly. Limiting holes 6 are also opened on both side surfaces of the track frame 5; a connecting plate 7 is movably installed inside the guide rail 4. A rotating shaft is installed at one end of the connecting plate 7 close to the inner wall of the guide rail 4. The connecting plate 7 can rotate through the rotating shaft; a limiting block 8 is fixed on one side of the connecting plate 7 close to the limiting hole 6 and passes through the inside of the limiting hole 6. The limiting block 8 and the limiting hole 6 are arranged at intervals. After the track frame 5 moves along the surface of the guide rail 4, the limiting holes 6 on the surface of the track frame 5 can be aligned with the limiting holes 6 on the surface of the guide rail 4, so that the limiting block 8 passes through the middle of the guide rail 4 and the track frame 5 at the same time, and the limiting block 8 restricts the position of the track frame 5. At the same time, the track frame 5 can be moved between two groups of limiting blocks 8, and the limiting blocks 8 support on both sides of the track frame 5, thereby restricting the movement range of the track frame 5; a torsion spring 9 is installed on the side of the connecting plate 7 away from the limiting block 8. One end of the torsion spring 9 away from the connecting plate 7 is fixed to the inner wall of the guide rail 4. When the torsion spring 9 is not under pressure, the torsion spring 9 pushes the connecting plate 7 towards the outside of the guide rail 4, so that the limiting block 8 on the surface of the connecting plate 7 is restricted inside the limiting hole 6. When the track frame 5 needs to be adjusted, the two connecting plates 7 are moved closer to each other from the bottom of the guide rail 4. When the connecting plate 7 rotates around the rotating shaft, the limiting block 8 moves with the connecting plate 7 and disengages from the inside of the limiting hole 6 at the same time, so that there are no obstacles on the surface of the guide rail 4, which is convenient for the track frame 5 to move on the surface of the guide rail 4. After the track frame 5 determines its position, the connecting plate 7 is released. The connecting plate 7 is reset again by the thrust of the torsion spring 9, and the limiting block 8 is pushed into the limiting hole 6 opened on the guide rail 4 again, thereby restricting the movement of the track frame 5.

[0030] A through hole 10 is provided inside the guide rail 4, and a control rod 11 is installed inside the through hole 10. One end of the control rod 11 close to the support plate 1 2 is fixedly connected with a fixing plate 12. Fixing blocks 1 13 are fixed on both sides of the fixing plate 12. One end of the control rod 11 away from the fixing plate 12 is fixed with a fixing block 2 14. An activity groove is provided on the surface of the slider on the side of the guide rail 4 close to the fixing block 2 14, and a sliding groove is provided on the side of the support plate 2 3 close to the support plate 1 2, which facilitates the movement of the fixing block 2 14 in the sliding groove during adjustment. A compression spring 16 is sleeved on the outer ring of the control rod 11 close to one end of the fixing plate 12. One end of the compression spring 16 away from the fixing plate 12 is fixed with a backing plate. When the fixing plate 12 is pulled outwards, the compression spring 16 is compressed. When the fixing plate 12 is released, the compression spring 16 pushes the control rod 11 towards the support plate 2 3 by pushing the backing plate, so that the control rod 11 is reset.

[0031] Fixing grooves 15 are provided on the outer surfaces of both the support plate 1 2 and the support plate 2 3. The fixing groove 15 provided on the support plate 2 3 is communicated with the sliding groove provided inside. The fixing blocks 1 13 and the fixing block 2 14 can be clamped with the fixing groove 15, so as to fix the position of the control rod 11. And the control rod 11 is sleeved in the through hole 10 provided on the guide rail 4. After the control rod 11 is fixed, the height of the guide rail 4 is also restricted. When adjusting the height of the guide rail 4, the fixing plate 12 can be pulled in a direction away from the support plate 1 2, so that the fixing plate 12 drives the fixing block 1 13 to disengage from the inside of the fixing groove 15. And when the fixing plate 12 moves, the fixing block 2 14 is also driven by the control rod 11 to disengage from the fixing groove 15 provided on the support plate 2 3. The fixing block 2 14 enters the sliding groove provided on the support plate 2 3 from the fixing groove 15 and moves up and down with the adjustment of the height of the guide rail 4, so that the guide rail 4 can move up and down normally. When the guide rail 4 reaches the appropriate height, the fixing block 1 13 is pushed back into the inside of the fixing groove 15 through the fixing plate 12, so that the control rod 11 drives the fixing block 2 14 to be clamped with the fixing groove 15 on the side of the support plate 2 3, so as to fix the position of the guide rail 4 and prevent the guide rail 4 from moving freely.

[0032] Working principle: When adjusting the position of the track frame 5, by moving the two connecting plates 7 at the bottom of the guide rail 4 closer to each other, the connecting plates 7 drive the limit blocks 8 to retract into the guide rail 4 while rotating inwards when moving inwards, so that the track frame 5 can move freely on the surface of the guide rail 4. After the position of the guide rail 4 is determined, the connecting plates 7 are released. The connecting plates 7 are reset by the torsion springs 9, and the limit blocks 8 are inserted into the limit holes 6 again, so as to limit the position of the track frame 5 and prevent the track frame 5 from moving freely.

[0033] When installing the silk thread into the placement groove on the top of the track frame 5, the pressing rod on the side of the track frame 5 can be lifted upwards to facilitate the placement of the silk thread pair. After the silk thread is placed, the pressing rod is pressed into the groove to fix the position of the pressing rod and prevent the silk thread from pushing the pressing rod.

[0034] When adjusting the height position of the adjustment guide rail 4, pull the fixed plate 12 laterally towards the support plate 2 to loosen it, so that the fixed plate 12 drives the first fixed block 13 out of the inside of the fixed groove 15. While the fixed plate 12 is moving, the fixed plate 12 drives the second fixed block 14 to move simultaneously through the control rod 11, so that both sides of the guide rail 4 are in a movable state. After the height position of the guide rail 4 is determined, loosen the fixed plate 12 to reset the compression spring 16. When the compression spring 16 is reset, it pushes the control rod 11 to move, so as to reinsert the first fixed block 13 and the second fixed block 14 into the corresponding fixed grooves 15, completing the fixation of both sides of the guide rail 4.
