[0024] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] refer to Figure 1 A live binding tool comprises an insulating operating rod 6, a connecting column, a binding unit, a locking unit 10 and a binding plate 8. The connecting column is installed at one end of the insulating operating rod 6 for controlling the binding unit and the locking unit 10; the binding unit is installed on the binding plate 8 for fixing the binding plate 8 on the porcelain bottle 3; the locking unit 10 is installed on the binding plate 8 for fixing the wire 1 on the porcelain bottle 3.

[0026] refer to Figure 4 The binding unit includes a support frame 4, a binding line 9, a shell 5, a first ratchet 11 group and a rotating shaft 14. The support frame 4 is mounted on the binding plate 8, the shell 5 is mounted on the support frame 4, and the rotating shaft 14 is mounted on the support frame 4 and one end thereof penetrates into the shell 5. The first ratchet 11 group includes a ratchet 11 and a pawl 12. The ratchet 11 is mounted on one end of the rotating shaft 14 located in the shell 5. The pawl 12 is rotatably mounted in the shell 5 through a torsion spring. The pawl 12 cooperates with the ratchet 11 to limit the rotating shaft 14 to rotate in only one direction. An engaging groove corresponding to the connecting column is provided at one end of the rotating shaft 14 away from the ratchet 11. The cross-sectional shapes of the engaging groove and the connecting column are both non-rotating bodies, such as triangles, squares, etc., to prevent the rotating shaft 14 and the connecting column from slipping.

[0027] refer to Figure 4 The first limiting unit includes a sleeve 13, a spring 16 and a ball 15. The sleeve 13 is rotatably mounted on the support frame 4, and one end of the sleeve 13 is located in the shell 5. The rotating shaft 14 is rotatably mounted in the sleeve 13. The ratchet 11 is fixedly mounted on the sleeve 13. The rotating shaft 14 is provided with a movable groove 17 at one end close to the ratchet 11. The ball 15 is slidably mounted in the movable groove 17. The spring 16 is installed in the movable groove 17, and the two ends are elastically supported by the bottom of the movable groove 17 and the ball 15 respectively. A spherical groove 18 corresponding to the ball 15 is provided on the inner wall of the sleeve 13. Both ends of the binding line 9 pass through the binding plate 8 and are connected to the sleeve 13.

[0028] Before use, you first need to install the binding wire 9 and the locking wire 7 in the locking hook and the binding plate 8 respectively, make sure that the size of the circle formed by the binding wire 9 is larger than the porcelain bottle 3, make sure that the materials and components required for the binding process are in the correct position, and then insert the connecting column into the fitting groove. The connecting column here is connected to the insulating operating rod 6 by a latch and a rotating shaft 14, and the fixed angle needs to be adjusted before use. The function of the insulating operating rod 6 is to provide the necessary operating distance to ensure that the operator works within a safe range. Then, the operator uses the insulating operating rod 6 to control the locking unit 10 to hook the wire 1 and buckle the wire 1 on the porcelain bottle 3. Then, the insulating operating rod 6 is rotated, so that the connecting column drives the rotating shaft 14 to rotate. At this time, a part of the ball 15 will enter the spherical groove 18 under the action of the spring 16, and the rotating shaft 14 drives the sleeve 13 and the ratchet 11 to rotate through the ball 15. The rotation of the sleeve 13 will make the binding wire 9 connected to the sleeve 13 wrap around the sleeve 13, reducing the length of the binding wire 9, and the binding plate 8 is fixed to the porcelain bottle 3 by tightening the binding wire 9. When the tightening force of the binding wire 9 reaches the set value, the ball 15 will break away from the spherical groove 18 and enter the movable groove 17 completely, no longer meshing with the spherical groove 18, and the rotating shaft 14 and the sleeve 13 will rotate relative to each other. Damage to the live binding tool caused by excessive tightening of the binding wire 9 is avoided. The pawl 12 cooperates with the ratchet 11 to prevent the rotating shaft 14 from reversing and ensure the stability of the binding wire 9.

[0029] The tying plate 8 is provided with an opening which is engaged with the porcelain bottle 3 , and the opening can be sleeved on the porcelain bottle 3 , so as to increase the stability between the tying plate 8 and the porcelain bottle 3 .

[0030] refer to Figure 3 , the locking unit 10 includes a locking wire 7, a second ratchet 11 group, a locking hook and a second limiting unit. The first ratchet 11 group and the second ratchet 11 group have the same structure, the first limiting unit and the second limiting unit have the same structure, and the functions they realize are also the same, except that the installation positions are different, which will not be described in detail here. Locking hooks are installed at both ends of the binding plate 8, and the locking hooks are used to hook the wire 1. One end of the locking hook is connected to the locking wire 7, the second ratchet 11 group is installed on the binding plate 8, and the second limiting unit is installed on the second ratchet 11 group. The other end of the locking wire 7 is connected to the second limiting unit. When the binding wire 9 is fixed, the insulating operating rod 6 can be manipulated to disengage the connecting column from the rotating shaft 14, and the connecting column is controlled to connect with the locking unit 10, and then the insulating operating rod 6 is rotated again to allow the locking wire 7 to be wound around the second locking unit 10 and tightened, thereby tightening the locking hook, increasing the force of the locking hook on the wire 1, and ensuring the stability of the live binding tool fixed to the wire 1. When the tightening force of the binding wire 9 reaches a set value, the second limiting unit will be activated to prevent the locking wire 7 from being over-tightened.

[0031] refer to Figure 2The locking hook includes a hook 201 and a connecting piece. Both ends of the tying plate 8 are rotatably connected to the middle of the connecting piece. One end of the hook 201 is rotatably connected to one end of the connecting piece, and the other end of the connecting piece is connected to the locking wire 7. The locking wire 7 drives the connection of the connecting plate 202, so that most of the contact surface of the hook 201 can contact the wire 1, and the tension of the hook 201 can always be kept perpendicular to the wire 1, so as to avoid excessive pressure between the hook 201 and the wire 1, which may cause damage to both.

[0032] A guide cylinder for facilitating the entry of the connecting column is installed at one end of the sleeve 13 away from the support frame 4. The guide cylinder is trumpet-shaped, and the large-scale trumpet mouth reduces the difficulty of the operator's alignment. When the connecting column enters the guide cylinder, it can slide into the fitting groove. A magnet is fixedly installed in the fitting groove, and the connecting column is made of a material that can be magnetically attracted, such as iron, cobalt, nickel and its alloys. The magnetic force of the magnet further guides the connecting column to enter the fitting groove, which reduces the difficulty of use and improves work efficiency. At the same time, the magnet can also increase the connection strength between the connecting column and the rotating shaft 14, avoiding the situation where the connecting column is separated from the rotating shaft 14 when the insulating operating rod 6 is raised to control the live binding tool to hook the wire 1. When the live binding tool completes the fixation of the wire 1, the insulating operating rod 6 can be retracted.

[0033] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
