Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

As shown in fig. 1 and 2, the utility model provides a nut dismounting tool, which comprises a sleeve 1, a jacking device and a long handle 3. The sleeve 1 is a hollow structure having a cavity 10 therein. A plurality of through holes are provided in the inner wall of the sleeve 1 along the circumferential direction thereof, and in order to better fit the nut, 6 through holes are provided at equal intervals in the side wall of the sleeve 1 in the present embodiment. Correspondingly, this nut extracting tool includes 6 tight devices in top, and 6 tight devices in top wear to establish in 6 through-holes one-to-one. Each jacking device comprises a connecting piece arranged in the through hole in a penetrating way, a pressing part 20 vertically connected with one end of the connecting piece positioned in the cavity 10 and a spring 21 sleeved on the connecting piece and positioned between the inner side wall of the sleeve and the pressing part. In order to be able to press the nut better when screwing it, an internal thread is provided on the inner wall of the through-hole, in this embodiment the connecting piece is a bolt 22, the external thread on the bolt 22 being adapted to the internal thread in the through-hole so that the bolt 22 is fixed to the through-hole by a threaded connection. The bolt is further sleeved with a spring 21, the elastic force of the spring 21 can tighten or loosen the nut, and in order to press the nut better, the length of the spring 21 is set to be in a compressed state when the bolt 22 is screwed to a limit position in the direction close to the axial center of the sleeve 1 in the through hole, namely the pressing part 20 is closest to the axial center of the sleeve 1. A pressing part 20 is vertically welded at one end of the bolt 22 in the cavity 10, and the pressing part 20 can be a plate-shaped body, wherein the pressing part 20 on each jacking device is parallel to one outer side face of the nut. The pressing parts 20 on the 6 jacking devices surround the cavity 10 to form a clamping space with a regular hexagon section.

In order to assist in aligning the nut, an infrared beam emitting device 4 is provided on the axis of the sleeve 1, and the infrared beam emitting device 4 is connected to a power supply through a circuit. In addition, a circle of LED bulbs 5 are arranged on the end surface of one end of the sleeve 1, and the LED bulbs 5 are also connected with a power supply through a circuit. The power source, which may be a battery or dry cell, is disposed within the cavity 10. And a long handle 3 for easy holding is provided at the other end of the sleeve 1, and a jack 30 is provided at the end side of the long handle 3 away from the sleeve, and when screwing the nut, a bar is inserted into the jack 30, and the nut is screwed by rotating the bar to rotate the sleeve 1. In addition, in order to facilitate the electric nut dismounting, the end part of the long handle 3 far away from the sleeve 1 is provided with a motor interface 31 which can be butted with a motor. The motor interface 31 is connected with a motor, and the nut can be rotated by the motor.

When the nut dismounting tool of the embodiment is used for screwing the nut, the infrared beam transmitter 4 is turned on to emit an infrared beam, the infrared beam is aligned with the center of the nut, and the LED lamp 5 can be turned on in a place where light is not bright to illuminate so as to assist in alignment. Screwing the bolt 22 in the through hole to enable the compression part 20 connected with the bolt to move close to the side wall of the sleeve 1, so that the space enclosed by the 6 compression parts 20 is slightly larger than the peripheral size of the nut, adjusting the sleeve 1 to enable each compression part 20 to be parallel to one of the outer side faces of the nut, screwing the bolt 22 inwards, driving the compression parts 20 to move close to the nut by the bolt 22, when the bolt 22 cannot be screwed any more, the compression parts 20 are tightly pressed on the outer side faces of the nut, namely when the 6 compression parts are tightly pressed on each outer side face of the nut respectively, the nut is tightly clamped in the clamping space enclosed by the 6 compression parts 20, and at the moment, a rod is inserted into the insertion hole 30, and the sleeve 1 is rotated through the rotating rod to loosen or tighten the nut. Of course, the motor interface 31 on the long handle 3 can also be connected with a motor, and the motor drives the long handle 3 to rotate so as to screw the nut.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood that the invention is not limited thereto, and that various modifications and changes can be made by those skilled in the art without departing from the principles of the invention.
