Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The inner wall of the bottom end of the movable plate 8 is elastically connected with a block 10 through a reset spring 9. The outer wall of the rotating shaft 2 is provided with a notch corresponding to the block 10, so that the block 10 can be plugged into the outer wall of the rotating shaft 2, so as to limit the position of the entire movable plate 8 and the movable ring 7. The outer wall of the rotating shaft 2 is rotatably connected with a positioning plate 11, and the top of the positioning plate 11 is fixedly connected with a supporting mechanism. The top of the positioning plate 11 is rotatably connected with a U-shaped frame 13 through the supporting mechanism. The middle part of the U-shaped frame 13 can allow the cable to pass through, and there is a pulley on the U-shaped frame 13, which can contact the cable through the pulley, so as to avoid wear and tear during the cable threading process.

[0032] Reference Figure 3-Figure 5 The inner wall of the U-shaped frame 13 passes through and is fixedly connected with a round tube 14. The inner wall of the bottom end of the round tube 14 is elastically connected with a pressing plate 16 through a positioning spring 15. The height of the pressing plate 16 is equal to the inclined surface of the wedge block 17. When the pressing plate 16 completely enters the round tube 14, the inclined surface of the wedge block 17 will be squeezed by the inner wall groove of the support plate 12. The right end of the pressing plate 16 is fixedly connected with a wedge block 17. The wedge block 17 is an inclined surface. In its initial state, the wedge block 17 is completely inserted into the inner wall groove of the support plate 12, and the inclined surface of the wedge block 17 cannot be squeezed.

[0033] The support mechanism includes a support plate 12, which is fixedly connected to the top of the positioning plate 11, and the round tube 14 is penetrated and rotatably connected to the inner wall of the support plate 12. The inner wall of the support plate 12 is provided with a notch corresponding to the wedge block 17, so that the wedge block 17 can be inserted into the inner wall of the support plate 12 to limit the entire U-shaped frame 13. The outer wall of the support plate 12 contacts the inner side wall of the U-shaped frame 13, and the inner wall of the bottom end of the round tube 14 is fixedly connected to one end of the positioning spring 15, and the positioning spring The other end of the spring 15 is fixedly connected to the bottom end of the pressing plate 16. When the pressing plate 16 moves downward, the positioning spring 15 is compressed. When resetting, the elastic force of the positioning spring 15 is used to reset the pressing plate 16. The pressing plate 16 and the wedge block 17 penetrate and are slidably connected to the inner wall of the circular tube 14. The circular tube 14 is respectively provided with slots for the pressing plate 16 and the wedge block 17 to slide, so that the pressing plate 16 and the wedge block 17 can move vertically, and the wedge block 17 is plugged into the inner wall of the support plate 12.

[0034] Reference Figure 1-Figure 3 The inner wall of the bottom end of the moving plate 8 is fixedly connected to one end of the return spring 9. When the moving plate 8 moves downward, the return spring 9 will be compressed. When resetting, the elastic force of the return spring 9 is used to reset the block 10. The other end of the return spring 9 is fixedly connected to the bottom end of the block 10. The block 10 penetrates and is slidably connected to the inner wall of the moving plate 8. The block 10 is plugged into the outer wall of the rotating shaft 2. The positioning plate 11 is slidably connected to the top of the support seat 1. The positioning plate 11 can slide on the support seat 1, allowing the U-shaped frame 13 to approach the cable for subsequent pipe threading procedures. The moving plate 8 is slidably connected to the outer wall of the rotating shaft 2.

[0035] Working principle: First, when the number of turns of the cable needs to be increased, only the block 10 needs to be moved downward and the reset spring 9 needs to be compressed to separate the block 10 from the outer wall notch of the rotating shaft 2, and then the movable plate 8 needs to be moved outward with the movable ring 7 and the sleeve 6, so that the sleeve 6 can slide on the outer wall of the sliding tube 5 and increase the space for the number of turns of the cable wrapped around the sleeve 6 and the sliding tube 5. When limiting, only the block 10 needs to be released and the reverse elastic force of the reset spring 9 needs to be used to reset the block 10, so that the block 10 can be plugged into the outer wall of the rotating shaft 2, and then the cable can be rolled up between the sleeve 6 and the sliding tube 5 without replacing pipe threaders of different sizes.

[0036] Before the pipe needs to be threaded, the positioning plate 11 only needs to be moved to the right to allow the U-shaped frame 13 to be close to the cable. When the direction of the cable threading needs to be adjusted, the pressing plate 16 only needs to be pressed to allow the pressing plate 16 to move downward with the wedge 17 and initially compress the positioning spring 15. When the pressing plate 16 completely enters the circular tube 14, the inclined surface of the wedge 17 will be squeezed by the notch on the inner wall of the support plate 12. By rotating the circular tube 14 left and right, the notch on the inner wall of the support plate 12 will squeeze the inclined surface of the wedge 17, allowing the wedge 17 to continue to move downward and compress the positioning spring 15. When the wedge 17 coincides with the notch on the next support plate 12, After that, the reverse elastic force of the positioning spring 15 is used to reset the pressing plate 16 and the wedge block 17. When the U-shaped frame 13 needs to be limited, it is only necessary to loosen the pressing plate 16 and use the reverse elastic force of the positioning spring 15 to reset the wedge block 17. At this time, the pressing plate 16 exposes the outer wall of the round tube 14, and the wedge block 17 completely enters the inner wall groove of the support plate 12 without being squeezed. The position of the entire U-shaped frame 13 is limited. When the U-shaped frame 13 rotates to the left, the cable will extend downward when threading. When the U-shaped frame 13 rotates to the right, the cable will extend upward when threading. There is no need to manually control the direction of the cable threading.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
