[0026] The total working principle is that, during use, according to the use requirement, the two ends of the drive shaft 3 are connected with the wire rollers 8 through the connecting mechanism 11, then the mobile hooks on the steel wires outside the two wire rollers 8 are connected with the wire clamps at the ends of the two wires, then the reciprocating swing of the handle 5 is manually controlled, the first ratchet on the handle 5 matches the first ratchet wheel 4 to control the rotation of the drive shaft 3, since the ends of the drive shaft 3 are connected with the wire rollers 8, the rotation of the two wire rollers 8 is simultaneously controlled to pull the two wires, if the pulling of one wire is completed during use, the position of the wire roller 8 at this position is positioned through the locking assembly, then the connection between the wire roller 8 and the end of the drive shaft 3 is released through the connecting mechanism 11, and the rotation of one wire roller 8 is controlled when the handle 5 swings again, the device has great practicability and is suitable for use in different situations.

[0027] In the embodiment, the end of the fixed hook 2 penetrates into the inside of the rectangular frame 1, and the end of the fixed hook 2 is fixed with a limiting block, and the fixed hook 2 is rotatably connected with the rectangular frame 1.

[0028] The local working principle is that the fixed hook 2 can rotate at the end of the rectangular frame 1, so that the angle of the fixed hook 2 is conveniently adjusted, the horizontal state of the rectangular frame 1 is ensured, and the operation is convenient.

[0029] In the embodiment, the handle 5 comprises a sleeve 17, a slide rod 18 and a limiting assembly, the slide rod 18 is slidably installed in the inside of the sleeve 17, and the limiting assembly is arranged between the slide rod 18 and the sleeve 17 to fix the position of the slide rod 18.

[0030] The local working principle is that, during use, the slide rod 18 can slide in the inside of the sleeve 17 when the two wires are pulled at the same time, the position of the slide rod 18 is fixed through the fixing assembly, the use length of the handle 5 is increased, and the operation is more labor-saving.

[0031] In the embodiment, the limiting assembly comprises a contraction groove 19, a spring 20, an insertion block 21 and a positioning hole 22. The contraction groove 19 is arranged on the side of the slide rod 18. The spring 20 is arranged at the bottom of the contraction groove 19. The insertion block 21 is slidably arranged in the contraction groove 19. The positioning hole 22 is arranged on the outer side of the sleeve 17.

[0032] The local working principle is that when the slide rod 18 is controlled to slide, the insertion block 21 is pressed into the contraction groove 19, then the slide rod 18 is controlled to move, and after the required length is reached, the insertion block 21 is aligned with the positioning hole 22. The insertion block 21 is automatically reset under the action of the spring 20 and is inserted into the positioning hole 22 to position the slide rod 18.

The second ratchet 10 is arranged on one side of the frame 6. The end of the second ratchet 10 is inserted into the tooth groove on the outer side of the second ratchet wheel 9.

[0034] The local working principle is that in the process of winding rotation of the wire roller 8, the second ratchet 10 does not hinder the rotation of the second ratchet wheel 9, can automatically position the position of the wire roller 8, and prevent the wire roller 8 from slipping. If the second ratchet wheel 9 has a reverse rotation trend, the second ratchet 10 will block the reverse rotation of the second ratchet wheel 9.

[0035] In the embodiment, the connecting mechanism 11 comprises a first insertion slot 12, a second insertion slot 13, a connecting plate 14, a rectangular insertion rod 15 and an adjusting screw 16. The connecting plate 14 is parallel to the side of the rectangular frame 1 and is located between the rectangular frame 1 and the horizontal rod 7.

The end of the wire roller 8 is provided with the second insertion slot 13 which is inserted with the rectangular insertion rod 15. The two ends of the rectangular insertion rod 15 are located in the first insertion slot 12 and the second insertion slot 13 respectively. The adjusting screw 16 is rotatably arranged on the two sides of the rectangular frame 1 and is threadedly connected with the connecting plate 14.

[0036] The local working principle is that in the process of use, the adjusting screw 16 is rotated to control the horizontal movement of the connecting plate 14. The movement of the connecting plate 14 drives the movement of the rectangular insertion rod 15. When the two ends of the rectangular insertion rod 15 are inserted into the first insertion slot 12 and the second insertion slot 13, the driving shaft 3 can drive the rotation of the two groups of wire rollers 8 at the same time. When the rectangular insertion rod 15 is only inserted into the first insertion slot 12, the wire roller 8 at this position will not rotate with the driving shaft 3 and only perform single wire pulling.

[0037] In the embodiment, the connecting plate 14 is provided with a sliding hole. One end of the frame 6 passes through the inside of the sliding hole.

[0038] Local working principle: the process of connecting plate 14 sliding, using the end of the frame 6 can be limited to connecting plate 14, ensure that the connecting plate 14 moves horizontally.

[0039] The above is only further embodiments of the present application, but the scope of protection of the present application is not limited to this, any skilled in the art of the technical personnel in the range disclosed by the present application, according to the technical scheme and the conception of the present application to equivalent replacement or change, all belong to the protection scope of the present application.
