[0002] As an indispensable key element in the connection of automobile parts, automobile bolts play an extremely important role in ensuring the stability of the overall structure of the automobile and the collaborative operation of various parts. It is mainly composed of a screw rod and a head with external threads. The common shapes of the head are hexagonal and dodecahedral, which facilitate tightening operations using wrenches and other tools. The screw rod part has various thread specifications, with differences in parameters such as thickness and pitch, which can precisely adapt to various connection scenarios according to different connection positions and stress requirements.
[0003] During routine maintenance and repair of automobiles, a common problem often encountered is the difficulty in removing the nuts on existing automobile bolts using a wrench. As a highly integrated and complex mechanical system, automobiles have a compact internal structure with closely arranged parts. Many bolts and nuts are installed in small spaces surrounded by numerous parts, such as the engine compartment, which is filled with various pipelines, electronic components, and other mechanical parts. When it is necessary to remove a bolt at a specific location, the direction of rotation of the wrench is easily blocked by these adjacent parts. The wrench may encounter engine blocks, radiators, oil pipes, or other fixed supports during its normal rotation path, preventing it from completing a full rotation and effectively applying sufficient torque to the nut, making it difficult to operate the bolt removal smoothly. This not only increases the difficulty and time cost of maintenance personnel, but also may cause accidental damage to surrounding parts due to repeated attempts to remove the bolt improperly.

[0024] When the normal wrench is blocked when rotating the nut on the bolt of the automobile, the nut can be disassembled by moving the arc-shaped plates 7 to the two sides of the nut, then moving the middle part of the guide rail B5 on the two sides by the electric telescopic rod 802 (controlling the extension and retraction of the two electric telescopic rods 802 by the remote controller), thereby moving the two arc-shaped plates 7 to the middle part, clamping the nut, then holding the turning part 2, and rotating the driving rod 1 from the other direction (rotating direction of 90 degrees) to disassemble the nut. The specific steps are as follows: the driving rod 1 changes the rotating direction by 90 degrees through the turning part 2, drives the rotation of the guide rail A3, and drives the rotation of the arc-shaped plate 7, so that the nut moves along the screw rod and is disassembled. During disassembly, the nut drives the sliding block B6 to slide along the guide rail B5, so that the rotating direction is adjusted to overcome the problem that the rotating direction of the ordinary wrench is blocked and the complete rotating stroke cannot be completed, thereby facilitating the disassembly of the nut on the bolt.
[0025] Furthermore, the bottom end of the sliding block B6 is fixedly connected with a magnet A11, and the bottom end of the guide rail B5 is fixedly connected with a magnet B12, that is, the sliding block B6 is located at the lowermost part of the guide rail B5 in the initial state, at which time the magnet A11 and the magnet B12 attract each other, limiting the position of the arc-shaped plate 7, so that the two arc-shaped plates 7 are aligned with each other, facilitating the clamping of the nut by the two arc-shaped plates 7.
[0026] The specific structure of the turning part 2 is as follows: the turning part 2 comprises a bevel gear A201 and a bevel gear B202 connected with each other, and an L-shaped plate B204, the back of the bevel gear A201 and the bevel gear B202 are fixedly connected with a rotating rod 203, the two ends of the L-shaped plate B204 are rotatably supported on the rotating rod 203 through a bearing 205, the rotating rod 203 on the bevel gear A201 is connected with the driving rod 1, the rotating rod 203 on the bevel gear B202 is connected with the guide rail A3, and the surface of the L-shaped plate B204 is fixedly connected with a stabilizing rod 206.
[0027] After the two arc-shaped plates 7 clamp the nut, the worker holds the turning part 2 with one hand by holding the stabilizing rod 206, and rotates the driving rod 1 with the other hand, which drives the rotation of the bevel gear A201, the bevel gear A201 drives the rotation of the bevel gear B202, and the guide rail B5 is driven to rotate.
