DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] A wrench is a commonly used installation and disassembly tool, which is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners that hold the openings or holes of bolts or nuts. A wrench is usually provided with a clamping handle at one or both ends of the handle. By applying an external force, the bolt or nut holding the opening or hole of the bolt or nut can be turned. When in use, an external force is applied to the handle along the direction of thread rotation to turn the bolt or nut. The size of the current wrench opening is manually adjusted. For nuts of different sizes, the size of the wrench opening needs to be adjusted first, and then the nut needs to be loosened or tightened. In addition, the wrench opening cannot be automatically reset, which makes the operation troublesome. In view of this, the utility model provides an adjustable wrench and a multi-purpose tool, which can realize automatic resetting of the wrench opening, facilitate the adjustment of the wrench opening size, and facilitate the use of users.

[0031] Embodiment 1:

[0032] like Figure 1-5As shown, the movable wrench includes a wrench body 1, a movable arm 6 and a spring 8, the wrench body 1 includes a fixed seat 2 and a cover plate 3 that are fixedly connected, the fixed seat 2 and the cover plate 3 have a accommodating cavity 4, and the cover plate 3 is provided with a first limiting hole 5; the movable arm 6 is rotatably connected to the accommodating cavity 4, and the movable arm 6 is provided with a second limiting hole 7; the spring 8 is installed in the movable arm 6, one end of the spring 8 abuts against the first limiting hole 5, and the other end of the spring 8 abuts against the second limiting hole 7.

[0033] In the present movable wrench, the movable arm 6 is rotatably connected in the accommodating chamber 4. When in use, the movable wrench is rotated to clamp it onto the nut. Since the spring 8 is installed in the movable arm 6, one end of the spring 8 abuts against the first limiting hole 5, and the other end of the spring 8 abuts against the second limiting hole 7. The spring 8 presses the movable arm 6, and the movable arm 6 presses the nut under the action of the spring 8. At this time, the movable wrench clamps the nut, and the nut can be tightened by rotating the movable wrench. After tightening and loosening, the movable wrench is removed, and the movable arm 6 is reset under the action of the spring 8, and there is no need to manually reset it. When it is necessary to tighten nuts of different types, it is only necessary to open the movable arm 6 to fit the size of the nut of the changed type, which greatly facilitates the adjustment of the wrench opening and is convenient for use.

[0034] like Figure 1 and 2 As shown, specifically, the fixing seat 2 and the cover plate 3 are connected by rivets 9. In the above-mentioned movable wrench, a rotating shaft 10 is arranged in the accommodating cavity 4, and the movable arm 6 is rotatably connected to the rotating shaft 10.

[0035] like Figure 1-5 As shown, in this embodiment, the movable arm 6 is provided with a spanner hook 11, and the spanner hook 11 is provided with a first spanner tooth 12. The spanner body 1 is provided with a second spanner tooth 13, and the second spanner tooth 13 is arranged opposite to the first spanner tooth 12. In this structure, by providing the first spanner tooth 12 on the hand hook and the second spanner tooth 13 on the spanner body 1, when loosening or tightening the nut, friction is increased, and the loosening or tightening of the nut is facilitated.

[0036] like Figure 2 As shown, in this embodiment, a guide column 14 is provided in the movable arm 6 , and the spring 8 is sleeved on the guide column 14 .

[0037] Embodiment 2:

[0038] like Figure 6-7 As shown, this embodiment provides a multi-purpose tool, including a tool body 21 and the above-mentioned adjustable wrench, the adjustable wrench is rotatably connected to the tool body 21. Specifically, the tool body 21 is provided with a rotating shaft 15, and the adjustable wrench is rotatably connected to the rotating shaft 15.

[0039] like Figure 6-7 As shown, in this embodiment, a limiting portion 16 is provided on the tool body 21, and a limiting block 17 is provided on the movable wrench. When the movable wrench is opened, the limiting block 17 abuts against the limiting portion 16. In this structure, when the movable wrench is opened, the limiting block 17 abuts against the limiting portion 16, and the limiting portion 16 limits the limiting block 17, that is, limits the movable wrench to prevent the movable wrench from rotating excessively.

[0040] like Figure 6-7 As shown, in this embodiment, a telescopic rod 18 is provided on the tool body 21, and a groove 22 is provided on the movable wrench. When the movable wrench is closed, the telescopic rod 18 is clamped in the groove 22. In this structure, when the movable wrench is closed, the movable wrench is rotated, and when the groove 22 on the movable wrench rotates to the telescopic rod 18, the telescopic rod 18 can limit the movable wrench, effectively preventing the movable wrench from rotating excessively.

[0041] like Figure 6-7 As shown, in this embodiment, the movable wrench is provided with a first slot 19 and a second slot 20, the tool body is provided with a spring sheet 23, and the spring sheet 23 is provided with a protrusion 24; when the movable wrench is opened, the protrusion 24 is engaged in the first slot 19; when the movable wrench is closed, the protrusion 24 is engaged in the second slot 20. In this structure, when the movable wrench is opened, the movable wrench is rotated and the protrusion 24 is engaged in the first slot 19. The protrusion 24 locks the movable wrench to prevent the movable wrench from rotating excessively. At this time, the limit block 17 abuts against the limit portion 16. When in use, the limit block 17 effectively limits the movable wrench to ensure that the movable wrench can be used normally without moving; when the movable wrench is closed, the protrusion 24 is engaged in the second slot 20 to prevent the movable wrench from loosening when the multi-purpose tool is stored. The spring sheet 23 provides elastic force for the protrusion 24, so that the protrusion 24 is automatically engaged in the first slot 19 or the second slot 20.

[0042] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
