[0020] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art. Embodiment 1:

[0021] See also Figure 1 The present application provides an adjustable steel bar binding device, including an installation base pipe 1, a binding hook 2, a wire wheel 3, a torsion spring 4, a driving pipe 5, and a first steel rope 6; the cross-sections of the installation base pipe 1 and the driving pipe 5 are circular, rectangular, elliptical, etc., and are made of rigid materials, and the outer diameter of the installation base pipe 1 matches the inner diameter of the driving pipe 5.

[0022] The upper end of the tying hook 2 extends into the mounting base tube 1, and is rotatably connected to the mounting base tube 1 through the first one-way bearing 7; the upper end of the tying hook 2 is also rotatably installed with a wire wheel 3 through the second one-way bearing 8, and the wire wheel 3 is located above the first one-way bearing 7; a torsion spring 4 is installed in the mounting base tube 1 through a positioning shell, one end of the torsion spring 4 is fixedly connected to the positioning shell, and the other end is fixedly connected to the wire wheel 3; a steering wheel 9 located on one side of the wire wheel 3 is rotatably installed on the mounting base tube 1; a driving tube 5 that moves up and down with a shell is slidably installed on the upper end of the mounting base tube 1; one end of the first steel rope 6 is wound around the wire wheel 3, and the other end is fixedly connected to the driving tube 5 after passing around the steering wheel 9.

[0023] Among them, the first one-way bearing 7 and the second one-way bearing 8 can rotate in opposite directions, and the torsion spring 4 drives the wire wheel 3 to rotate in the rotatable direction of the second one-way bearing 8. The following describes in detail the use process of the device on the assumption that the first one-way bearing 7 can rotate clockwise and the second one-way bearing 8 can rotate counterclockwise.

[0024] When in use, after hooking the end of the tying hook 2 onto the tying wire, pull the driving tube 5 upwards, and the driving tube 5 pulls the first steel rope 6 upwards, and the first steel rope 6 is continuously released from the reel 3, while driving the reel 3 to rotate. Since the second one-way bearing 8 can only rotate counterclockwise, the rotating reel 3 drives the tying hook 2 to rotate clockwise, so that the wire is firmly tied without turning the wrist, thereby reducing wrist fatigue and wrist soreness.

[0025] When the wire wheel 3 rotates clockwise, the torsion spring 4 is tightened. After the binding is completed, the end of the binding hook 2 is separated from the wire. Under the action of the torsion spring 4, the wire wheel 3 rotates counterclockwise, and the first steel rope 6 is rewound onto the wire wheel 3, and the installation base pipe 1 is pulled upward to reset, waiting for the next binding work to be carried out.

[0026] When separating the end of the tying hook 2 from the iron wire, since the tying hook 2 is in close contact with the iron wire, it is usually necessary to slightly reverse it by a certain angle to loosen the contact position between the tying hook 2 and the iron wire, thereby facilitating the removal of the tying hook 2. In this application, by making the tying hook 2 non-rotatable counterclockwise, when the tying hook 2 is reversed, the tying hook 2 will not twist at will, and reversing the tying hook 2 is more convenient.

[0027] In this embodiment, a rubber sleeve can be put on the outer surface of the driving tube 5 to increase the friction between the driving tube 5 and the palm, making it easier to pull the driving tube 5. The outer surface of the driving tube 5 can also be set to a concave-convex shape that adapts to the palm (not shown in the figure).

[0028] In this embodiment, in order to facilitate the connection between the first steel rope 6 and the driving tube 5, the top thread of the driving tube 5 is screwed with a connecting screw with a middle opening, and the upper end of the first steel rope 6 can be passed through the through hole and tied into a knot, thereby firmly connecting the first steel rope 6 to the driving tube 5. Embodiment 2:

[0029] Based on Example 1, Figure 2 and Figure 3 As shown, in this embodiment, a movable pulley 10 and a second steel rope 12 are also included.

[0030] The movable pulley 10 is installed in the installation base pipe 1 so as to be movable up and down through the slider 11. The upper end of the first steel rope 6 is fixedly connected to the slider 11; one end of the second steel rope 12 is fixedly connected to the installation base pipe 1, and the other end is fixedly connected to the driving pipe 5 after passing around the movable pulley 10.

[0031] When the driving tube 5 is pulled upward, the movable pulley 10 can effectively reduce the required pulling force, thereby reducing the labor intensity of the staff. Especially when thicker iron wire is required for steel bar binding, the labor-saving design is more important.

[0032] Optionally, in this embodiment, two relatively arranged slide grooves 101 are constructed in the mounting base tube 1, and there are two sliders 11, which are respectively slidably installed in the two slide grooves 101, and the two sliders 11 are respectively fixedly connected to the movable pulley 10, thereby realizing a sliding connection between the movable pulley 10 and the mounting base tube 1.

[0033] Optionally, in the present embodiment, the movable pulley 10 includes two oppositely arranged side guard assemblies 1001 and a rotating shaft 1002, and the opposite sides of the two side guard assemblies 1001 are respectively constructed with grooves, and the two ends of the rotating shaft 1002 are respectively embedded in the grooves, so as to be rotatably connected with the side guard assemblies 1001; the two side guard assemblies 1001 are respectively fixedly connected to the sliders 11 on the corresponding sides; the locking bolt 13 passes through the slider 11, one of the side guard assemblies 1001, the rotating shaft 1002, and the other side guard assembly 1001 in sequence from one end of one of the sliders 11, and is then threadedly screwed with the other slider 11.

[0034] When both end surfaces of the rotating shaft 1002 are respectively fitted with the two side guard assemblies 1001 , the gap between the two side guard assemblies 1001 is smaller than the diameter of the second steel rope 12 .

[0035] When the binding wire is thicker, by loosening the locking bolt 13, the gap between the two side guard assemblies 1001 is made larger than the diameter of the second steel rope 12, so that the second steel rope 12 can slide between the two side guard assemblies 1001, thereby achieving a labor-saving effect.

[0036] When the iron wire used for binding is thinner, the two side guard assemblies 1001 are clamped with the second steel rope 12 by tightening the locking bolt 13. When the second steel rope 12 is pulled, the movable pulley 10 is directly driven to move, so that the binding hook 2 rotates faster to improve work efficiency.

[0037] In this embodiment, in order to facilitate the rotation of the locking bolt 13, a through hole matching the end of the locking bolt 13 is constructed on the driving tube 5, so that the end of the locking bolt 13 is exposed outward, thereby facilitating its rotation. Furthermore, the end of the locking bolt 13 is embedded in the through hole, which can effectively prevent the installation base tube 1 and the driving tube 5 from rotating relative to each other, which is beneficial to the structural stability of the device.

[0038] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
