Description

Technical Field

[0001] This utility model belongs to the field of tool technology, specifically relating to a quick-use multi-purpose wrench. Background Technology

[0002] Socket wrenches have a wide range of applications. They are suitable for bolts or nuts in confined spaces or recesses. They consist of a tubular wrench shaft and a handle on the shaft. When in use, the handle rotates the wrench shaft, which in turn rotates the bolt or nut to tighten or loosen it.

[0003] However, existing socket wrenches have the following problems when used: 1. The handle of the socket wrench is either fixed or movable. The fixed handle is not suitable for some narrow spaces, while the movable handle is not easy to disassemble or to fix after adjustment, which can cause instability of the main rod when tightening.

[0004] Second, socket wrenches have poor stability when tightening, requiring the hand to hold the main rod. However, if too much force is applied while holding the main rod, it becomes inconvenient to tighten, while if too little force is applied, the main rod will wobble. Summary of the Invention

[0005] To address the problems mentioned in the background section, the purpose of this utility model is to provide a quick and versatile wrench.

[0006] This utility model discloses a quick-use multi-purpose wrench, comprising a main rod, an adapter, an aluminum sleeve, a retaining ring, a spring, a steel ball, and a sliding rod. An installation head is integrally connected to the front end of the main rod, and an adapter is fixedly connected to the rear end of the main rod. The adapter has a insertion hole, and an installation groove is formed on the inner wall of the insertion hole. A spring is fixedly connected within the installation groove, and a steel ball is positioned at the front end of the spring and movably connected within the installation groove. The sliding rod is inserted into the insertion hole, and the aluminum sleeve is fitted onto the outside of the main rod. A retaining ring groove is formed on the front side of the main rod, and the retaining ring engages within the retaining ring groove to fix the aluminum sleeve onto the main rod.

[0007] As a preferred embodiment, the insertion hole is a hexagonal insertion hole.

[0008] As a preferred embodiment: the slide bar is a hexagonal bar, and the two sides and the middle of one side wall of the slide bar are provided with locking grooves, and the steel balls are locked in the locking grooves.

[0009] As a preferred embodiment, guide arcs are provided at both ends of the slide rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the T-type and L-type can be switched at will through the cooperation of the main rod, adapter, aluminum sleeve, snap ring, spring, steel ball and slide rod. At the same time, the slide rod is not easy to fall off, and the stability is high. It can be operated with one hand or two hands, saving time and effort.

[0011] I. This utility model uses an aluminum sleeve to provide hand support, thereby improving the stability of the main rod and making it less prone to wobbling when operated with both hands.

[0012] Second, this utility model allows for easy switching between T-type and L-type configurations via a sliding rod within the adapter. The sliding rod also enables quick installation and disassembly, saving time and effort. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. The structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0018] Combination Figures 1 to 3The following is a description of this specific embodiment, which adopts the following technical solution: It includes a main rod 1, an adapter 2, an aluminum sleeve 3, a retaining ring 4, a spring 5, a steel ball 6, and a sliding rod 7. The front end of the main rod 1 is integrally connected to an installation head, which can accommodate sleeves, sleeve-type screwdriver bits, adapters, etc. The rear end of the main rod 1 is fixedly connected to the adapter 2, which has a insertion hole 2-1. The insertion hole 1-1 is a hexagonal insertion hole, allowing the sliding rod 7 to be inserted. An installation groove is formed on the inner wall of the insertion hole 2-1, and a spring 5 is fixedly connected within the installation groove. A steel ball is provided at the front end of the spring 5. The ball 6 is movably connected in the mounting groove. The slide rod 7 is inserted into the insertion hole 2-1. The aluminum sleeve 3 is sleeved on the outside of the main rod 1. The front side of the main rod 1 is provided with a retaining spring groove 1-1. The retaining spring 4 is engaged in the retaining spring groove 1-1 to fix the aluminum sleeve 3 on the main rod 1. The retaining spring 4 can fix the aluminum sleeve 3 and the aluminum sleeve 3 can rotate on the main rod 1. The slide rod 7 is a hexagonal rod. The two sides and the middle of one side wall of the slide rod 7 are provided with retaining grooves 7-1. The ball 6 is engaged in the retaining grooves 7-1. Both ends of the slide rod 7 are provided with guide arcs. The guide arcs can enable the slide rod 7 to be quickly inserted into the insertion hole 2-1.

[0019] The working principle of this specific implementation method is as follows: 1. Installation: Insert the slide rod 7 directly into the hexagonal hole of the adapter 2. The inclined surface at the top of the slide rod 7 will press the steel ball 6 inward slightly. When the locking groove 7-1 of the slide rod 7 moves to the position of the steel ball 6, the spring 5 pushes the steel ball 6 outward, so that it clicks into the locking groove 7-1. The steel ball 6 locks the locking groove 7-1 of the slide rod 7, so that it does not fall off. T-type and L-type can be switched at will.

[0020] 2. Disassembly: Hold the T-shaped rod with one hand and pull the slide bar 7 backward with the other hand. The inner wall will press the steel ball 6 to move, causing it to completely exit the groove of the adapter 2. Keep it in the pulled-back state and pull the slide bar out completely. The spring will return to its original position, ready to receive the next slide bar.

[0021] III. Operation: When tightening is required, a socket, socket-type bit, and adapter are installed on the mounting head of the main rod 1. During tightening, the slide rod 7 switches positions within the adapter 2 as needed, enabling switching between T-type and L-type. When two-handed operation is required, the hands hold the aluminum sleeve 3. During tightening, the main rod 1 can rotate within the aluminum sleeve 3, which improves the stability during tightening.

[0022] The advantages of this specific implementation method are as follows: 1. The main rod and adapter adopt a new friction welding process. The main rod is made of high-hardness material, and the hexagonal screws are tightly engaged, making it stable and preventing stripping, and making operation more convenient.

[0023] 2. T-type and L-type screws can be switched at will, making it easier to deal with stubborn screws.

[0024] 3. Extremely fast replacement, much faster than traditional magnetic or clamp-type designs.

[0025] 4. One-handed operation: With practice, you can complete the operation very smoothly with one hand.

[0026] 5. Highly versatile, suitable for various scenarios, one solution does it all.

[0027] 6. Secure the steel ball in the adapter and ensure the slide bar is firmly in place to prevent it from falling off.

[0028] 7. The aluminum sleeve allows for both hands to exert force, saving time and effort.

[0029] 8. The surface is electroplated, making it smooth and beautiful, and it will not rust even after long-term use.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
