[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] This embodiment provides a foldable portable repair tool, such as Figure 1-8 As shown, the repair tool includes three first arms 1 extending outward in a circular array with a fulcrum 11, a second arm 12 provided at an end of the first arm 1 away from the fulcrum 11, a hexagon socket 13 fixedly provided at an end of the second arm 12 away from the first arm 1, and an adjustment mechanism 2 provided between the first arm 1 and the second arm 12;

[0026] The adjusting mechanism 2 includes a first connecting block 22 arranged on the first arm 1, a second connecting block 24 arranged on the second arm 12, and a hinged plate 23 whose two ends are hinged on the first connecting block 22 and the second connecting block 24 respectively. The second arm 12 is slidably sleeved with a positioning cylinder 21 for connecting with the first arm 1. The inner wall of the positioning cylinder 21 is relatively provided with a first guide groove 211 and a second guide groove 212. The second guide groove 212 is provided with an expansion groove 213 and a circular hole 214 interconnected with the expansion groove 213 at one end close to the first connecting block 22. The outside of the second arm 12 is annularly distributed with a number of guide rail plates 3 for matching with the first guide groove 211 and the second guide groove 212. The outside of the first arm 1 is relatively fixedly connected with a first limit block 25 corresponding to the second guide groove 212, and the outside of the first arm 1 is correspondingly fixedly connected with a second limit block 27 corresponding to the first guide groove 211.

[0027] Specifically, the first connecting block 22 and the second connecting block 24 have the same specifications, and the two ends of the hinge plate 23 are hinged to the first connecting block 22 and the second connecting block 24 respectively to realize the folding operation between the first arm 1 and the second arm 12. The hinge tightness between the first connecting block 22, the second connecting block 24 and the hinge plate 23 is large, and force needs to be applied to twist when the angle needs to be adjusted. The first limit block 25 and the second limit block 27 have the same specifications. The first guide groove 211 and the second guide groove 212 opened on the inner wall of the positioning cylinder 21 are adapted to the first limit block 25 and the second limit block 27, so that the positioning cylinder 21 can be guided to move. The expansion groove 213 opened on the second guide groove 212 serves to facilitate the connection of the limit column 26 to the circular hole 214 close to the limit column 26. Four guide rails 3 are distributed in a ring shape on the outside of the second arm 12, and the four guide rails 3 serve to limit and guide the movement of the positioning cylinder 21.

[0028] A sliding cavity is provided inside the first limit block 25 , in which a spring 111 is provided. One end of the spring 111 is fixedly connected to a limit column 26 , which is movably interlaced with the first limit block 25 , and one end of the limit column 26 away from the spring 111 is chamfered.

[0029] More specifically, a spring 111 is installed in the sliding cavity opened in the first arm 1 and cooperates with the limit column 26 so that the limit column 26 can be inserted into the circular hole 214 on the positioning cylinder 21 to ensure that the first arm 1 and the second arm 12 are positioned in the same horizontal state, thereby ensuring that the hexagonal socket 13 can avoid angular deviation when installing or removing the bolt.

[0030] A magnet block 31 is provided at one end of the guide rail 3 away from the first arm 1 .

[0031] It should be noted that the magnet block 31 provided on the guide rail plate 3 is used to position the positioning cylinder 21 by magnetic attraction after it moves to the hexagonal socket 13. It mainly plays the role of positioning the positioning cylinder 21 after the first arm 1 and the second arm 12 are folded, and prevents the positioning cylinder 21 from sliding along the path of the second arm 12 due to shaking.

[0032] When in use, first move the hexagonal sleeve 13 to adjust the second connecting block 24 on the second arm 12 to the same horizontal line as the hinge plate 23, and then continue to move the hinge plate 23 to the same horizontal line as the first arm 1. At this time, the first arm 1 and the second arm 12 are in a straight line. At this time, move the positioning cylinder 21 from the hexagonal sleeve 13 to the first arm 1 until the expansion groove 213 on the positioning cylinder 21 is inserted and positioned by the limit column 26. At this time, hold the first arm 1 to install the bolt It can be assembled or disassembled. After use, manually squeeze the relatively distributed limit columns 26 inward along the circular hole 214 on the positioning cylinder 21, and then move the positioning cylinder 21 toward the inner hexagonal sleeve 13 until the positioning cylinder 21 is adsorbed and fixed by the magnet block 31. Manually move the hinge plate 23 ninety degrees from the first connecting block 22, and the second connecting block 24 and the hinge plate 23 are similarly moved ninety degrees. At this time, the entire first arm 1 is in a folded state, which reduces the overall occupied space and is convenient to carry.

[0033] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
