[0014] 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.

[0015] Example 1

[0016] refer to Figures 1 to 3, an improved extended hexagonal wrench, comprising a handle body 1, an extended rod body 2, and a bolt 3 for fixing the extended rod body 2, the handle body 1 is provided with a connecting piece 13, the handle body 1 is provided with a first chamber 121 for inserting the extended rod body 2, the connecting piece 13 is provided with a second chamber 131, the first chamber 121 and the second chamber 131 are communicated with each other and form a right angle, the second chamber 131 is provided with a thread 1311 matching the bolt 3, one end of the extended rod body 2 is provided with a positioning groove 21, and the other end is provided with a hexagonal mold 22 for disassembling or installing the hexagonal socket bolt, the bolt 3 is used to press the positioning groove 21 to fix the end of the extended rod body 2 in the first chamber 121;

[0017] Under this design, before use, the end of the extension rod 2 with the positioning groove 21 is inserted into the first cavity 121. The worker can adjust the depth of the insertion into the first cavity 121 according to the actual working situation, thereby adjusting the length of the extension rod 2 protruding from the first cavity 121. After adjusting the length, the bolt 3 is gradually screwed into the second cavity 131. Since the first cavity 121 and the second cavity 131 form a right angle, the bolt 3 can more effectively fix the positioning groove 21. After fixing the extension rod 2, the worker only needs to align the end with the hexagonal mold 22 with the position of the hexagon socket bolt and insert it into the groove of the hexagon socket bolt, and then turn the handle body 1, so that the hexagon socket bolt can be installed and removed; in this way, when the worker applies force to the wrench to remove or install the hexagon socket bolt, the extension rod 2 will not shake or become unstable after long-term use, and the extension rod 2 will not become loose or fall due to accidental touch during the work process.

[0018] In this embodiment, the handle body 1 is a T-shaped structure, including a horizontal portion 11 and a vertical portion 12, the first chamber 121 is located in the vertical portion 12, and the connecting member 13 is located on one side of the vertical portion 12;

[0019] Specifically, the vertical portion 12 is located in the first chamber 121, and the first chamber 121 forms a right angle with the second chamber 131 in the connecting member 13, so that when the bolt 3 is screwed into the extension rod 2, the bolt 3 can better fix the extension rod 2;

[0020] Whether the worker operates with one hand or two hands, the T-shaped handle body 1 can better adapt to the grip of the human hand, providing a larger gripping area to facilitate the worker to better apply force to the handle body 1. When operating with one hand, the worker can hold the middle of the horizontal part 11, clamp the vertical part 12 with fingers, and then rotate the handle body 1 to remove or install the hexagon socket bolt. When operating with two hands, the worker can hold one end of the horizontal part 11 with one hand and the other end of the horizontal part 11 with the other hand, so that both hands can simultaneously rotate the handle body 1 clockwise or counterclockwise to remove or install the hexagon socket bolt.

[0021] More preferably, the handle body 1 and the connecting piece 13 are integrally formed; the handle body 1 and the connecting piece 13 are integrally formed so as to facilitate processing and manufacturing.

[0022] In this embodiment, the extension rod body 2 is a cylindrical structure, and the positioning groove 21 is a rectangular structure; the extension rod body 2 with a cylindrical structure has a uniform cross-section, can withstand pressure more effectively, and reduce the risk of deformation and breakage. Since the positioning groove 21 is a rectangular structure, when the extension rod body 2 is inserted into the first chamber 121, the worker can adjust the insertion depth into the first chamber 121 according to the required length, and align part of the positioning groove 21 with the second chamber 131, so that when the bolt 3 is gradually screwed in, the bolt 3 will press the positioning groove 21, thereby fixing the extension rod body 2.

[0023] Preferably, the diameter of the extended rod body 2 is larger than the diameter of the circumscribed circle of the hexagonal mold 22; the diameter of the extended rod body 2 is larger than the diameter of the circumscribed circle of the hexagonal mold 22, so that the extended rod body 2 can withstand greater torque and avoid deformation and breakage of the extended rod body 2.

[0024] The extended rod body 2 is integrally formed with the hexagonal mold 22; the extended rod body 2 and the hexagonal mold 22 are integrally formed to facilitate processing and manufacturing, reduce weak links at the connection, improve the overall strength, reduce the possibility of deformation, and reduce the loss of parts.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
