UTILITY MODEL CONTENT

[0006] Further, the outer shell is in the shape of a bottle with different diameters at both ends, the length of the supporting guide rollers and the limiting guide rollers in the outer shell is matched with the diameter of the outer shell, the inner diameter of the outer shell gradually decreases from one end to the other end, and the space in the outer shell is limited.
[0007] Further, the supporting guide rollers and the limiting guide rollers are both columnar structures with grooves on the surface, and the length of the grooves is proportional to the length of the supporting guide rollers and the limiting guide rollers, so as to limit the position of the wire rod.
[0008] Further, the telescopic rod is always in a relaxed state and pushes the supporting rod to the center position of the guide groove, so as to ensure that the supporting rod has enough space to move.
[0009] Further, the limiting guide roller is aligned between every two adjacent supporting guide rollers.

[0012] Compared with the prior art, the utility model has the following advantages:
[0013] The outer shell body is in the shape of a bottle with different diameters at the two ends, and the length of the supporting guide roller and the limiting guide roller inside the outer shell body is matched with the diameter of the outer shell body, so that the inner diameter of the outer shell body gradually decreases from one end to the other end, the space inside the outer shell body is limited, thereby limiting the shaking amplitude of the wire, allowing the wire to have a large shaking amplitude when it just enters the inside of the outer shell body, but when the wire moves to the other side, the inner diameter of the outer shell body gradually decreases, the wire loses the shaking space and tends to gradually stabilize.
[0014] 2. The telescopic rod is always in a relaxed state and pushes the supporting rod to the center position of the guide groove, ensuring that the supporting rod has enough space to move, the supporting guide roller and the limiting guide roller are both columnar structures with grooves on the surface, and the length of the grooves is proportional to the length of the supporting guide roller and the limiting guide roller, which limits the position of the wire, and pushing the limiting guide roller close to the supporting guide roller by the telescopic rod to limit the position of the wire will not limit the shaking of the wire, allowing the wire to shake while limiting the movement path of the wire, and gradually reducing the movement range of the wire, thereby gradually relieving the shaking of the wire, and reducing the friction generated when the wire moves through the rotating connection between the supporting guide roller and the limiting guide roller and the wire, thereby avoiding affecting the movement path of the wire and other safety accidents.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] like Figures 1-5 As shown, the outer shell 1 is divided into upper and lower parts. The two ends of the outer shell 1 are not located on different horizontal lines, and there is an arc transition between the two ends, so that the overall structure has a curved arc, thereby restricting the movement path of the wire. The lower half of the outer shell 1 is evenly provided with a number of supporting guide rollers 2. The length of the supporting guide rollers 2 gradually decreases from right to left. The upper half of the outer shell 1 is provided with a number of guide grooves 3 on both sides. The supporting guide rollers 2 and guide grooves 3 inside the outer shell 1 are all arranged along the arc direction of the outer shell 1.
[0023] Each guide groove 3 is fitted with a support rod 4. The top of the support rod 4 is equipped with a telescopic rod 5 connected to the outer shell 1. The telescopic rod 5 is always in an extended state and pushes the support rod 4 to the center position of the guide groove 3, ensuring that the support rod 4 has sufficient room to move. A bearing 6 is provided between the telescopic rod 5 and the support rod 4. A limiting guide roller 7 is sleeved on the outside of the support rod 4, and the length of the limiting guide roller 7 is adapted to the supporting guide roller 2. The outer shell 1 is bottle-shaped with different diameters at both ends. The lengths of the supporting guide roller 2 and the limiting guide roller 7 inside the outer shell 1 are adapted to the diameter of the outer shell 1, so that the inner diameter of the outer shell 1 gradually decreases from one end to the other, limiting the internal space of the outer shell 1. The supporting guide roller 2 and the limiting guide roller 7 are both columnar structures with grooves on their surfaces, and the grooves are proportional to the lengths of the supporting guide roller 2 and the limiting guide roller 7, thus limiting the position of the wire. The limiting guide roller 7 is aligned with every two adjacent supporting guide rollers 2.
[0024] Working principle description: When in use, the wire enters through the larger diameter section of the outer shell 1 and is inserted between the supporting guide roller 2 and the limiting guide roller 7. At this time, the wire pushes the limiting guide roller 7 upward, which in turn pushes the telescopic rod 5 to retract through the support rod 4. The retracted telescopic rod 5 simultaneously presses down on the limiting guide roller 7 through the support rod 4, making the limiting guide roller 7 close to the wire. During the movement of the wire, the grooves on the surfaces of the supporting guide roller 2 and the limiting guide roller 7 gradually shrink, gradually increasing the restriction on the movement of the wire. This allows for some shaking when the wire enters the outer shell 1, but the wire moves smoothly when leaving the outer shell 1, avoiding the shaking of the wire from affecting its normal movement.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
