DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Depend on Figure 1-5 The utility model comprises a shell 1 and a copper wire 6, the front of the shell 1 is set to an open state, an upper opening 2 connected to the inside of the shell 1 is opened at the middle position of the top of the shell 1, and a rotatable upper wire roller 4 is fixedly installed at the bottom of the shell 1 and on the left side of the upper opening 2, a lower opening 3 connected to the inside of the shell 1 is opened at the middle position of the bottom of the shell 1, and a rotatable lower wire roller 5 is fixedly installed at the bottom of the shell 1 and on the right side of the lower opening 3, the copper wire 6 passes through the upper opening 2 at the top of the shell 1 and the lower opening 3 at the bottom and bypasses the upper wire roller 4 and the lower wire roller 5 in turn, three fixed rods 7 are fixedly installed on the left side of the inner wall of the shell 1 from top to bottom, and a rotatable first roller 8 is installed at one end of the three fixed rods 7 away from the inner wall of the shell 1, and a movable plate 10 that can move left and right is movably installed on the right side of the inner wall of the shell 1, and at the top and bottom of the side of the movable plate 10 The two ends of the two connecting rods 12 are inserted with a connecting rod 12 at a height of 10, and a rod groove 13 is formed at one end of the two connecting rods 12 away from the inner wall of the shell 1. Insertion rods 14 are movably inserted in the two rod grooves 13. Connecting blocks 15 are fixedly installed at one end of the two insertion rods 14 outside the rod groove 13. A rotatable second roller 16 is installed at one end of the two connecting blocks 15 away from the insertion rod 14. The positions of the two second rollers 16 are staggered with the positions of the three first rollers 8 respectively. The part of the copper wire 6 located inside the shell 1 bypasses the three first rollers 8 and the two second rollers 16 in turn. By passing the copper wire 6 through the upper opening 2 and the lower opening 3 on the shell 1, and bypassing the upper wire roller 4 and the lower wire roller 5 in turn, and then controlling the hydraulic rod 9 to push the movable plate 10 to approach the first roller 8, the two second rollers 16 will squeeze the copper wire 6, so that the copper wire 6 is S-shaped between the three first rollers 8 and the two second rollers 16.

[0020] At the same time, the two rod grooves 13 are fixedly connected with the first springs 19 connected to the corresponding insertion rods 14, and the two connecting rods 12 and the corresponding connecting blocks 15 are fixedly connected with the second springs 20 sleeved on the insertion rods 14. When the copper wire 6 is loose or tight, the extrusion pressure on the second roller 16 will change. When the copper wire 6 is too loose, the first spring 19 and the second spring 20 will release the elastic force to push the second roller 16 to move to the left, thereby propping up the loose copper wire 6; when the copper wire 6 is too tight, the second roller 16 moves to the right due to the increased extrusion pressure, thereby preventing the copper wire 6 from being too tight.

[0021] In addition, the side walls of the two insertion rods 14 are provided with slots 17, and the open ends of the two rod slots 13 are fixedly installed with limiting rods 18. The two limiting rods 18 are respectively inserted into the slots 17 on the corresponding insertion rods 14. Through the cooperation between the limiting rods 18 and the slots 17, the insertion rod 14 can be prevented from escaping from the rod slot 13 at one end of the connecting rod 12.

[0022] In addition, a hydraulic rod 9 is fixedly installed on the right outer wall of the shell 1, and the telescopic end of the hydraulic rod 9 passes through the shell 1 and is fixedly connected to the middle position of the side of the movable plate 10. Four positioning rods 11 are fixedly installed on the right side of the inner wall of the shell 1. The four positioning rods 11 are respectively movable and pass through and inserted at the four corners of the side of the movable plate 10. By controlling the hydraulic rod 9, the movable plate 10 can be pushed to move, thereby driving the two connecting rods 12 on the movable plate 10 to move, and then the two second rollers 16 are moved closer to the first roller 8, and the four positioning rods 11 can make the movable plate 10 more stable when moving left and right.

[0023] Furthermore, the two second rollers 16 can be moved between two adjacent first rollers 8 under the push of the hydraulic rod 9. Through the mutual interlacing of the three first rollers 8 and the two second rollers 16, the copper wire 6 can be squeezed into an S shape, thus reserving space for the copper wire 6 to stretch.

[0024] Furthermore, the right end of the upper wire roller 4, the left end of the lower wire roller 5 and the right ends of the three first rollers 8 are all located in the same vertical plane.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
