[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] like Figure 1-Figure 5 As shown, the utility model discloses an adjustable hexagonal wrench, including a mounting seat 1 and a plurality of tool pieces 2. The mounting seat 1 is provided with a mounting portion 11 by means of integral molding or the like. Each of the tool pieces 2 is arranged on the mounting portion 11. Each of the tool pieces 2 includes an adjusting sleeve 21 and a working section 22. Each of the working sections 22 is arranged in a hexagonal prism. Each of the adjusting sleeves 21 is slidably installed in the mounting portion 11. Each of the adjusting sleeves 21 is provided with a positioning piece 211. Each of the positioning pieces 211 is detachably connected to the mounting portion 11 by means of bolts, buckles, etc. 1. Through the combined design of each tool piece 2, the user can quickly replace the working sections 22 of different sizes as needed to adapt to various specifications of hexagonal bolts or nuts, thereby improving the versatility and practicality of the tool. The user only needs to select tool pieces 2 of different sizes to cope with tasks of different specifications; 2. Since each adjusting sleeve 21 is slidably installed on the mounting portion 11 and the positioning piece 211 can be detachably connected to the mounting portion 11, the volume of the adjusting sleeve 21 located in the mounting portion 11 is changed and then fixed in the mounting portion 11, and the length of the adjusting sleeve 21 located in the mounting portion 11 is adjusted, so that the wrench can be suitable for screws of different depths. Specifically, deeper screw holes require the adjusting sleeve 21 to expose more of the mounting portion 11 to reach and fix the screws, while shallow screw holes require the adjusting sleeve 21 to slide toward the mounting portion 11 to avoid interfering with surrounding structures; 3. The adjustable length design allows one tool to meet the needs of various sizes and scenarios, reducing the need to carry and purchase wrenches of various specifications, and improving the versatility and economy of the tool.

[0025] Preferably, the mounting portion 11 is arranged in a Y-shape: 1. The Y-shaped design allows a plurality of tool pieces 2 of different sizes, usually three, to be integrated on a single tool, so that the user can quickly switch to the appropriate size to match different bolts or nuts without frequently changing tools, thereby improving work efficiency; 2. In narrow or hard-to-reach spaces, traditional linear wrenches may be difficult to operate, and the branch structure of the Y-shaped design can more easily enter these restricted areas, facilitating maintenance operations in engine compartments, furniture assembly or other compact spaces; 3. The Y-shaped layout allows the wrench to be better aligned with the surface of the bolt or nut when in use, and because there are three support points, the force is more evenly applied and ergonomic, making it easier to hold and reducing the risk of slipping, especially when a larger torque is required for tightening or loosening.

[0026] Among them, each positioning member 211 is rotatably installed on the corresponding adjustment sleeve 21, and the installation part 11 is provided with an installation groove 111 for each positioning member 211 to be inserted, and each installation part 11 is provided with a plurality of matching grooves 112 on the rotation track of each positioning member 211. Each positioning member 211 is located in one of the matching grooves 112 and is detachably connected to the installation part 11 by bolts, magnetic attraction, etc. Since each positioning member 211 is rotatably installed on the corresponding adjustment sleeve 21, after the adjustment sleeve 21 is installed in the installation part 11, each positioning member 211 is respectively inserted into the installation groove 111, and each positioning member 211 is rotated so that each positioning member 211 is The part 211 is located in one of the matching grooves 112 and then fixed with the mounting part 11 to realize the determination of the volume of the adjusting sleeve 21 located in the mounting part 11, that is, the length of each tool part 2 exposed from the mounting part 11 is adjusted to meet different usage requirements. When it is necessary to adjust the volume of the adjusting sleeve 21 located in the mounting part 11, the positioning part 211 is separated from the mounting part 11 and then rotated to move the adjusting sleeve 21 along the length direction of the mounting part 11 so that the positioning part 211 is located in different matching grooves 112 and then completes the connection with the mounting part 11 so that the volume of the adjusting sleeve 21 located in the mounting part 11 is determined.

[0027] Preferably, a first magnet 2111 is provided at the bottom of each of the positioning members 211, and a second magnet 113 that is mutually attracted to the first magnet 2111 is provided at each matching groove 112 of each mounting portion 11. Since the first magnet 2111 at the bottom of each positioning member 211 will be attracted to each second magnet 113, when the position of the adjusting sleeve 21 in the mounting portion 11 is adjusted so that the positioning member 211 is inserted into the matching groove 112 at a different position, the first magnet 2111 of the positioning member 211 will cooperate with the second magnet 113 at the corresponding position so that the positioning member 211 is stably located in the corresponding matching groove 112, so that in the absence of external force, the adjusting sleeve 21 will not move relative to the mounting portion 11, that is, the tool member 2 can be stably located on the mounting portion 11.

[0028] In addition, the tool 2 includes the same number of protective covers 3 as the tool pieces 2. Each of the tool pieces 2 is provided with a mounting disc 23 between the adjusting sleeve 21 and the working section 22. Each of the protective covers 3 is respectively sleeved on the circumference of the corresponding working section 22 and is detachably connected to the mounting disc 23 by means of snaps or the like. Each working section 22 is equipped with a protective cover 3, and the detachable connection between the protective cover 3 and the working section 22 is achieved by the mounting disc 23, which effectively prevents the working section 22 from being worn out due to contact with other objects when not in use and from causing injuries to unrelated persons in the hands of unrelated persons, thereby extending the service life of the tool.

[0029] Among them, each of the mounting discs 23 is provided with a plurality of limit plugs 231 at intervals along the circumferential direction, and each of the protective covers 3 is made of a material that is easy to deform and a limit slot 31 is provided corresponding to each of the limit plugs 231. Since each of the protective covers 3 is made of a material that is easy to deform, force is applied to each of the protective covers 3 so that the protective covers 3 are deformed and opened, so that each of the limit plugs 231 can be inserted into the corresponding limit slot 31. In the absence of external force, the protective cover 3 cannot rotate or move compared to the corresponding tool part 2, so that it can be stably installed on the corresponding tool part 2 to achieve the circumferential wrapping of the corresponding working section 22, so that unrelated personnel will not directly contact the working section 22 and dust will not accumulate on the working section 22 when not in use.

[0030] In addition, due to the arrangement of the mounting disc 23 and the limiting blocks 231 , when the adjusting sleeves 21 are slid inward, the mounting disc 23 will abut against the mounting portion 11 , so the mounting disc 23 and the limiting blocks 231 can limit the sliding path of the adjusting sleeves 21 .

[0031] Preferably, each of the limit blocks 231 is arranged along a step with a gradually decreasing width radially outward from the corresponding mounting disc 23. Since the width of the outer side of each limit block 231 is smaller than the width of the inner side, when each limit block 231 is installed into the mounting disc 23, the outermost end face of each limit block 231, i.e., the end face with the smallest width, will first enter the corresponding limit slot 31, thereby enabling each limit block 231 to cooperate with the corresponding limit slot 31 to realize the fitting connection between the mounting disc 23 and the protective cover 3.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
