[0002] When disassembling or installing parts such as screws and nuts on mechanical products, a pair of wrenches, screwdrivers and other tools are usually prepared. When using a screwdriver to disassemble or install the screws, the operator needs to continuously rotate the screwdriver in one direction to drive the screw to rotate for disassembly or installation. However, due to the limited rotation range of the human wrist, the operator needs to loosen the grip when holding the screwdriver and rotating it to a certain angle. At this time, the other hand is needed to assist the screwdriver to connect with the screw relative to prevent it from deviating, and then re-grip and rotate the screwdriver at a suitable angle. The operation is very troublesome and the work efficiency is low. Moreover, when the nut needs to be disassembled or installed, the operator needs to re-select the appropriate tool, and the tool is not portable and practical. Utility Model Content

[0018] The present invention will be further described below with reference to specific examples and accompanying drawings.

[0019] like Figure 1-4 As shown, the utility model describes a multifunctional wrench, comprising a handle body 1 and screwdrivers 2 installed on both sides of the handle body 1, wherein the handle body 1 is respectively provided with a first clamping hole 11 at both ends, and the middle portion of the handle body 1 is provided with a mounting channel 12 perpendicular to the handle body 1, a one-way bearing 13 is provided in the mounting channel 12, a rotating shaft 14 is passed through the one-way bearing 13, and both ends of the rotating shaft 14 extend out of the two ends of the mounting channel 12 respectively, and the two ends of the rotating shaft 14 are fixedly connected with a sleeve 15, and the screwdrivers 2 on both sides of the handle body 1 are detachably mounted on the sleeve 15.

[0020] When in use, the operator aligns one end of the screwdriver 2 with the nut hole of the screw to be operated. At this time, the screwdriver 2 is relatively fixed to the screw, and then the handle body 1 is partially rotated. When the rotation direction is the locking direction of the one-way bearing 13, rotating the handle body 1 can drive the one-way bearing 13 and the rotating shaft 14 to rotate in the same direction, thereby driving the sleeve 15 and the screwdriver 2 fixed on the sleeve 15 to rotate synchronously, thereby realizing the rotation of the screw. When the rotation direction is the movable direction of the one-way bearing 13, the rotating shaft 14 remains stationary when the handle body 1 is rotated, and will not drive the screw to rotate in the opposite direction. Therefore, the operator can realize the operation of always keeping the screw rotating in the same direction by reciprocatingly rotating the handle body 1, thereby tightening or removing the screw, and the handle body 1 is provided with a first clamping hole 11, which can be used to insert a nut to perform corresponding operations on the nut rotation;

[0021] The utility model provides screwdrivers 2 on both sides of the handle body 1, and the screwdriver 2 is assembled on the sleeve 15, and the sleeve 15 is fixed at both ends of the rotating shaft 14, and cooperates with the one-way bearing 13 to rotate unidirectionally in the installation channel 12, so that the screwdriver 2 can be driven to rotate unidirectionally by repeatedly rotating the handle body 1 in forward and reverse directions. A small movement can drive the screw to rotate quickly, avoiding the inconvenience of repeated plugging and unplugging, simple operation, time-saving and labor-saving, and the first clamping holes 11 at both ends of the handle body 1 enable it to have the function of nut disassembly and assembly, so that one thing can be used for multiple purposes. The operator can use one tool to achieve two functions, improve work efficiency, reduce work costs, and the tool is portable and practical.

[0022] The screwdriver 2 in the embodiment of the present invention includes a handle 21, a blade 22 and a blade head 23. The handle 21 is detachably mounted on the sleeve 15. An assembly groove 151 for connecting the handle 21 is provided at one end of the sleeve 15 away from the handle body 1, which facilitates the storage and carrying of the product. When the screwdriver 2 is removed from the sleeve 15, it can be stored more compactly, reducing the space occupied, and is more convenient whether placed in a tool box or carried with you.

[0023] Furthermore, in the embodiment of the utility model, an inner edge is provided on the inner surface of the assembly groove 151, and an outer edge 211 is provided on the outer surface of the handle 21, which enhances the stability of the connection between the handle 21 and the sleeve 15. The inner edge and the outer edge 211 cooperate with each other to effectively prevent the handle 21 from rotating or sliding in the assembly groove 151, ensuring that when the screwdriver 2 is used for operation, the handle 21 and the sleeve 15 maintain a firm connection state, avoiding affecting the accuracy and safety of the operation due to an unstable connection. When the handle 21 needs to be installed, the handle 21 can be quickly and accurately inserted into the assembly groove 151 through the guidance and positioning of the inner edge and the outer edge 211, thereby improving the installation efficiency. When the handle 21 needs to be removed, the handle 21 can be pulled out of the sleeve 15 more conveniently, which provides convenience for the user to replace the handle 21 or store it; in addition, the design of the inner edge and the outer edge 211 also increases the friction between the handle 21 and the sleeve 15, making it difficult for the handle 21 to fall off accidentally during use, further improving the reliability and practicality of the screwdriver 2.

[0024] Furthermore, the cross-sectional shape of the assembly groove 151 on the sleeve 15 is a regular hexagon. When the screwdriver 2 is pulled out, the sleeve 15 can be used as a nut removal tool, achieving multi-purpose use and high cost performance.

[0025] In order to make the screwdriver 2 more securely assembled in the sleeve 15, in some embodiments, a magnetic member (not shown in the figure) may be provided in the assembly groove 151. Correspondingly, a metal member or a magnetic member is provided on the handle 21, which greatly enhances the secure assembly of the screwdriver 2 in the sleeve 15. The magnetic force between the magnetic member and the metal member or another magnetic member can tightly adsorb the handle 21 after the handle 21 is inserted into the assembly groove 151, preventing the handle 21 from accidentally loosening during use, ensuring that the screwdriver 2 can maintain a stable connection state in various operating environments, and improving the safety and reliability of operation.

[0026] In the embodiment of the utility model, the blade heads 23 of the screwdriver 2 on both sides of the handle body 1 correspond to different screw models. The blade heads 23 of different models are integrated on one handle body 1, which greatly reduces the space occupied by the tool and the burden of carrying. It is convenient to use, especially for people who need to perform on-site maintenance frequently or work in an environment with limited space, and increases the flexibility and adaptability of the tool.

[0027] In this utility model, the mounting channel 12 is arranged perpendicular to the handle body 1, and the sleeve 15 is fixed along the extending direction of both ends of the mounting channel 12, forming an overall cross-shaped structure. When using the sleeve 15 or the screwdriver 2 for tightening or disassembly operations, the cross-shaped structure can evenly distribute the force, reducing the risk of deformation and damage to the tool and extending the service life of the tool. In addition, the stable structure can ensure the accuracy and reliability of operation and improve the quality of work.

[0028] Furthermore, in some embodiments, the two first snap-in holes 11 at both ends of the handle body 1 can be provided to correspond to different nut models, so that a multifunctional wrench can handle two different types of nuts without the need for frequent tool replacement, thereby greatly improving work efficiency.

[0029] The above embodiments are only preferred implementation methods of the present invention and are only used to explain the present invention rather than to limit the present invention. Any changes, replacements, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principles of the present invention shall be considered as equivalent replacement methods and shall be included in the scope of protection of the present invention.
