[0032] The inside of the positioning cylinder 4 is provided with a dismounting assembly 5, the dismounting assembly 5 includes a butt joint cylinder 51, a handle 52, a curved rod 54 and a clamp, the outer wall of the butt joint cylinder 51 is rotationally connected with the positioning cylinder 4, the end of the butt joint cylinder 51 is fixedly provided with the handle 52, and the handle 52 adjusts the torque to reduce the effort of rotating the nut.

[0033] As shown in the figure, Figure 2 The inside of the butt joint cylinder 51 is hollow, the screw 3 is inserted into the inside of the butt joint cylinder 51, a hexagonal groove 53 is arranged at the opening of the end of the butt joint cylinder 51, and the rusted nut on the screw 3 is embedded in the inside of the hexagonal groove 53.

[0034] The rusted nut is clamped by the hexagonal groove 53, and the inside of the butt joint cylinder 51 is hollow, so the screw 3 can be inserted into the inside of the butt joint cylinder 51, thereby avoiding that the rusted nut is fixed too far back on the screw 3 and cannot be clamped into the hexagonal groove 53.

[0035] The middle part of the tool rack 1 is rotationally connected with the curved rod 54, the end of the curved rod 54 is provided with a clamp, the clamp includes a middle plate 55 and a clamping rod 56, the side of the middle plate 55 is fixedly connected with the curved rod 54, the other side of the middle plate 55 is fixedly provided with two clamping rods 56 which are symmetrically arranged, the two clamping rods 56 clamp the screw 3, the side of the clamping rod 56 which faces the screw 3 is provided with friction teeth, and the teeth are embedded in the thread of the screw 3.

[0036] The curved rod 54 is fixedly provided with a foot pedal at the rotationally connected part with the tool rack 1, the position of the curved rod 54 is fixed by stepping on the foot pedal, the curved rod 54 is used to exert downward pressure on the clamping rod 56,

[0037] The teeth are embedded in the screw 3, and the end of the screw 3 abuts against the inside of the butt joint cylinder 51, when the screw 3 rotates, the screw 3 is hindered by the butt joint cylinder 51, when the screw 3 moves axially, the screw 3 is hindered by the friction teeth, and the screw 3 cannot move and rotate.

[0038] In this embodiment, the friction teeth on the clamping rod 56 are clamped into the thread of the screw 3 by rotating the curved rod 54, and the position of the clamping rod 56 is fixed by stepping on the curved rod 54, the butt joint cylinder 51 is rotated by the handle 52, thereby the rusted nut is dismounted from the screw 3, thereby facilitating the force dismounting of the rusted nut and accelerating the construction progress.

[0039] Embodiment 2

[0040] Based on the basis of embodiment 1, this embodiment proposes a special tool for dismounting rusted nuts for wire drawing, as shown inFigure 2 and Figure 3 As shown, an adjustment assembly 6 is provided on the top of the docking cylinder 51. The adjustment assembly 6 includes a threaded rod 61, a washer 62 and a semi-threaded arc plate 64. The middle part of the threaded rod 61 is slidably connected to two symmetrically arranged semi-threaded arc plates 64. The threaded rod 61 is threadedly connected between the two semi-threaded arc plates 64. The end of the threaded rod 61 is rotatably connected to the washer 62.

[0041] By rotating the threaded rod 61 along the thread direction of the semi-threaded arc plate 64, the washer 62 can be pushed into the interior of the mating cylinder 51, so that it rests against the rust nut, thereby improving the fit of this application to the size of the rust nut.

[0042] like Figure 2 and Figure 4 As shown, two symmetrically arranged slide rails 63 are fixedly installed in the middle of the docking cylinder 51. The semi-threaded arc plate 64 slides within the slide rails 63, and a plug block 65 is inserted into the gap between the slide rails 63 and the semi-threaded arc plate 64. Each of the two semi-threaded arc plates 64 has a built-in magnet, and the magnets on opposite sides of the two semi-threaded arc plates 64 have opposite magnetism.

[0043] By pulling out the insert 65 and sliding the semi-threaded arc plate 64, the threaded rod 61 and the semi-threaded arc plate 64 can be separated, allowing for quick up-and-down adjustment of the position of the shim 62. When the shim 62 is close to the rusted nut, the control of the semi-threaded arc plate 64 is released. As the threaded rod 61 continues to move downward, when the two semi-threaded arc plates 64 attract each other and can move, they adhere together. At this point, the threads inside the semi-threaded arc plate 64 align with the threads of the threaded rod 61. Finally, the insert 65 is inserted again for positioning. This avoids a large size difference between the previously removed rusted nut and the subsequent rusted nut, which would require too many rotations of the threaded rod 61 to adjust the position of the shim 62, thus affecting work efficiency.

[0044] In this embodiment, by separating the semi-threaded arc plate 64, the threaded rod 61 can be quickly adjusted to coarsely adjust the position of the shim 62. When the shim 62 is close to the rusted nut, the control of the semi-threaded arc plate 64 is released. When the thread in the semi-threaded arc plate 64 can mate with the thread of the threaded rod 61, the two semi-threaded arc plates 64 attract each other and can move. At this time, the thread in the semi-threaded arc plate 64 mates with the thread of the threaded rod 61, and then fine adjustment is performed.

[0045] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
