It is a commonly used tool for production, maintenance, and life. Sockets are suitable for turning bolts or nuts that are very narrow or deeply recessed. They can be divided into cold extruded sockets, tapered thread sockets, and straight thread sockets. They are composed of multiple sockets with hexagonal or twelve-pointed holes and equipped with handles, connecting rods, and other accessories.

[0003] The existing sleeve can only be used to twist and disassemble nuts that are not worn. When disassembling nuts that are worn on the surface, the edges and corners of the nut sides are worn and become smooth and cannot be installed in an adaptable manner with the inner angle of the sleeve. As a result, the sleeve cannot generate a torque when twisting the nut, which will cause thread slippage, making the worn nut difficult to disassemble. Therefore, a sleeve specifically for processing thread slipped nuts is needed to solve the above problem. Utility Model Content

Through the setting of the clamping mechanism, after the tapered rod moves downward, it will drive each The pressure plate moves downward, and the screw rod is driven to rotate by rotating the rotating plate. Since the limit rod limits the position of the pressure plate, the pressure plate is always facing the side end of the nut to prevent the pressure plate from changing its position. Therefore, the rotation of the screw rod will drive the pressure plate to move toward the side end of the nut until the pressure plate cooperates with the anti-slip pad to tightly press against the side end of the nut. At this time, the sleeve and the nut are fixed, so that the worn nut can be clamped and fixed. When the handle is turned, it is convenient to twist and disassemble the nut whose edges and corners have been worn and become smooth.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a sleeve for processing a stripped nut, comprising a handle 1, a fixing rod 2 is fixedly connected to the bottom end of the handle 1, a sleeve 3 is fixedly connected to the bottom end of the fixing rod 2, a nut 4 is arranged inside the sleeve 3, a thread groove 201 is provided at the bottom outer end of the fixing rod 2, a plurality of vertical grooves 301 are provided at the side end of the sleeve 3, a lifting mechanism for pressing the side end of the nut 4 downward is installed at the outer end of the thread groove 201, and a plurality of clamps for clamping the side end of the nut 4 are arranged between the bottom side end of the lifting mechanism and each vertical groove 301 The holding mechanism forms a large friction resistance between the sleeve 3 and the nut 4 by setting a lifting mechanism in the sleeve 3, so that the sleeve 3 will not easily rotate on the outside of the nut 4. The clamping mechanism is set so that the sleeve 3 can clamp and fix the worn nut 4. When the handle 1 is turned, the nut 4 whose edges have been worn and become smooth can be screwed and disassembled. When the sleeve 3 screws the nut 4, a twisting force can be generated, thereby facilitating the disassembly of the worn nut 4. Therefore, the sleeve 3 of the device can facilitate the disassembly of the nut 4 with stripped threads.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, the lifting mechanism includes a screw sleeve 5, which is threadedly connected to the thread groove 201, and a ring plate 501 is rotatably provided at the bottom end of the screw sleeve 5. The side end of the ring plate 501 is fixedly connected with a plurality of connecting plates 502, and the side end of each connecting plate 502 is fixedly connected with a bent plate 503, and the bottom end of each bent plate 503 is fixedly connected with a connecting rod 504, and each connecting rod 504 is inserted into the sleeve 3, and the bottom end of each connecting rod 504 is fixedly connected with a tapered rod 505, and the bottom end of each tapered rod 505 is fixedly connected with a vertical plate 506, and each clamping mechanism is respectively located between the side end of each vertical plate 506 and the side end of each vertical groove 301, and the side end of each vertical groove 301 is provided with a sliding groove 302. In implementation, by aligning the sleeve 3 with the nut 4 with worn corners, the screw sleeve 5 is rotated at this time so that the screw sleeve 5 is moved along the fixed The threaded groove 201 at the outer end of the rod 2 moves downward. At this time, since the screw sleeve 5 is rotatably arranged at the top of the ring plate 501, the screw sleeve 5 descends and can drive the ring plate 501, the connecting plate 502 and each bent plate 503 to move downward. At this time, each connecting rod 504 and each tapered rod 505 can be driven to move downward. Each tapered rod 505 moves downward corresponding to each angle of the side end of the sleeve 3 until the tapered rod 505 moves downward to between the angle of the sleeve 3 and the side end of the nut 4. At this time, since the upper end of the tapered rod 505 is thicker, when the screw sleeve 5 cannot rotate, each tapered rod 505 will be tightly pressed between the sleeve 3 and the nut 4, so that a large friction resistance is formed between the sleeve 3 and the nut 4, so that the sleeve 3 will not easily rotate on the outside of the nut 4, thereby facilitating the fixing of the nut 4 with the clamping mechanism and facilitating the screwing of the nut 4.

[0023] As an implementation method in this embodiment, Figure 3 and Figure 5As shown, the clamping mechanism includes a moving plate 6, the moving plate 6 is located in the vertical groove 301, the side end of the moving plate 6 is fixedly connected with a slider 601, the slider 601 is slidably connected in the slide groove 302, the side end of the moving plate 6 is threadedly connected with a screw 602, the side end of the screw 602 is fixedly connected with a rotating plate 603, the side end of the screw 602 is inserted into the side end of the vertical plate 506, the side end of the screw 602 is rotatably provided with a pressing plate 604, and the pressing plate 60 4 is fixedly connected to a plurality of limiting rods 606, each limiting rod 606 is inserted into the side end of the vertical plate 506, and the side end of the pressure plate 604 is fixedly connected to an anti-skid pad 605, which can improve the fixing effect of the pressure plate 604 on the nut 4. In practice, after the conical rod 505 moves downward, it will drive each pressure plate 604 to move downward. At this time, each pressure plate 604 will be located at the side end of the nut 4. At this time, the screw rod 60 The screw rod 602 is threadedly connected to the side end of the movable plate 6, and the screw rod 602 is driven to rotate by rotating the rotating plate 603. Since the limiting rod 606 limits the position of the pressing plate 604, the pressing plate 604 is always facing the side end of the nut 4 to prevent the pressing plate 604 from changing its position. Therefore, the rotation of the screw rod 602 will drive the pressing plate 604 to move toward the side end of the nut 4 until the pressing plate 604 cooperates with the anti-skid pad 605 to press tightly against the side end of the nut 4. At this time, the sleeve 3 is fixed to the nut 4, so that the worn nut 4 can be clamped and fixed. When the handle 1 is rotated, the nut 4 whose edges and corners are worn and become smooth can be screwed and disassembled. The arrangement of the tapered rod 505 and the pressing plate 604 allows the sleeve 3 to generate a twisting force when the nut 4 is screwed, so that the worn nut 4 is easy to disassemble. Therefore, the sleeve 3 of the device can be convenient for disassembling the nut 4 with stripped threads.

[0024] Working principle: by aligning the sleeve 3 with the nut 4 with worn edges and corners, the screw sleeve 5 is rotated to make the screw sleeve 5 move downward along the thread groove 201 at the outer end of the fixing rod 2. At this time, since the screw sleeve 5 is rotated and arranged at the top of the ring plate 501, the screw sleeve 5 descends and can drive the ring plate 501, the connecting plate 502 and each bent plate 503 to move downward. At this time, each connecting rod 504 and each tapered rod 505 can be driven to move downward. Each tapered rod 505 moves downward corresponding to each angle of the side end of the sleeve 3 until the tapered rod 505 moves downward between the angle of the sleeve 3 and the side end of the nut 4. At this time, since the upper end of the tapered rod 505 is thicker, when the screw sleeve 5 cannot rotate, each tapered rod 505 will be tightly pressed between the sleeve 3 and the nut 4, so that a large friction resistance is formed between the sleeve 3 and the nut 4, so that the sleeve 3 will not easily rotate on the outside of the nut 4. At this time, after the tapered rod 505 moves downward, it will drive each pressure plate 604 to move downward. When the handle 1 is turned, the nut 4 with the edges worn out can be easily removed by twisting the sleeve 3. When the handle 1 is turned, the nut 4 with the edges worn out can be easily removed.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
