Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for power equipment, specifically a T-head dual-purpose wrench. Background Technology

[0002] T-head wrenches, as a basic hand tool, are widely used in mechanical assembly, equipment maintenance, and construction engineering. Their structure consists of a vertical handle and a horizontal working end, providing high torque output, making them particularly suitable for space-constrained work environments. In recent years, with the increasing complexity of industrial equipment and the diversification of maintenance scenarios, traditional single-function wrenches have become insufficient to meet the demands for efficient operation, leading to integrated and multi-functional improvements.

[0003] Traditional T-wrenches often feature a fixed single-head design, requiring frequent tool changes to accommodate different bolt sizes, leading to low work efficiency. This is especially true in complex assembly scenarios like electrical boxes, where workers need to carry multiple wrench sets, increasing tool management costs and the risk of misoperation. The rigid connection between the head and handle of a conventional T-wrench makes angle adjustment difficult in confined spaces, restricting the direction of force application and increasing the risk of bolt damage. Furthermore, their low torque output efficiency and lack of auxiliary force-boosting mechanisms, relying solely on manual force application, makes them prone to slippage or fatigue damage when disassembling large bolts. Some low-end products, due to insufficient material hardness, are prone to head wear and deformation after prolonged use. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a T-head dual-purpose wrench, which has different specifications of internal hex wrench and socket wrench on both sides of the T-head, realizing multi-specification adaptation of a single tool. It can be used for efficient operation in narrow spaces and optimize human-machine interaction performance, significantly reducing maintenance and usage costs. It can be used in the assembly field and has significant market competitiveness.

[0005] To achieve the above objectives, a T-head dual-purpose wrench is designed, including a force-supplying handle. A ratchet mechanism is welded to the top of the force-supplying handle, and a counterweight is connected to the other end of the force-supplying handle. A rotating rod passes through the ratchet mechanism, with an internal hex wrench at one end of the rotating rod and a socket wrench at the other end.

[0006] The ratchet mechanism includes a ratchet, a groove, a locking pin, a spring, and a chuck. The chuck of the ratchet mechanism has a disc structure. The ratchet is located at the center of the disc. A groove is located around the ratchet inside the chuck. A spring is located at the bottom of the groove, and a locking pin is located at the top of the spring.

[0007] The chuck and ratchet are provided with a through hole at their center for the rotating rod to pass through.

[0008] The bottom of the locking pin is provided with an inclined surface, the inclination of which is consistent with the tooth profile angle of the ratchet tooth groove, so that the locking pin can engage and be fixed with the ratchet tooth groove.

[0009] The counterweight has a fixing bolt on one side and a groove on the other side, with a threaded hole inside the groove for connecting other counterweights.

[0010] Compared with the prior art, this utility model reduces the frequency of tool replacement. By installing a one-way ratchet, it achieves continuous one-way rotation, avoids repeated disassembly and assembly of the wrench, improves torque transmission efficiency, and embeds a counterweight at the end of the handle to adapt to the balance needs in different scenarios.

[0013] See Figures 1 to 2 1 is the force-supplying handle, 2 is the ratchet mechanism, 2.1 is the ratchet, 2.2 is the slot, 2.3 is the locking pin, 2.31 is the inclined plane, 2.4 is the spring, 2.5 is the chuck, 3 is the rotating rod, 4 is the counterweight, 5 is the Allen wrench, and 6 is the socket wrench. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, a ratchet mechanism 2 is welded to the top of the force-supplying handle 1, and a counterweight 4 is connected to the other end of the force-supplying handle 1. A rotating rod 3 passes through the ratchet mechanism 2. One end of the rotating rod 3 is equipped with an internal hex wrench 5, and the other end of the rotating rod 3 is equipped with a socket wrench 6. The internal hex wrench 5 and the socket wrench 6 are connected to the rotating rod 3 and can be adjusted by a small range of extension and retraction. The material of the force-supplying handle 1 can be 42CrMo alloy steel, which has high strength and toughness after gradient heat treatment, and has a high fatigue limit and resistance to repeated impacts.

[0016] like Figure 2 As shown, the ratchet mechanism 2 includes a ratchet 2.1, a groove 2.2, a locking pin 2.3, a spring 2.4, and a chuck 2.5. The chuck 2.5 of the ratchet mechanism 2 has a disc structure. The ratchet 2.1 is located at the center of the disc. The groove 2.2 is arranged around the ratchet 2.1 inside the chuck 2.5. The bottom of the groove 2.2 is provided with a spring 2.4, and the top of the spring 2.4 is supported by the locking pin 2.3. The ratchet 2.1 and the chuck 2.5 are made of wear-resistant alloy tool steel Cr12MoV. Through the meshing of the locking pin 2.3 and the ratchet 2.1, unidirectional continuous rotation is achieved, preventing the locking pin 2.3 from slipping out in the opposite direction.

[0017] The chuck 2.5 and ratchet 2.1 have through holes at their centers for the rotating rod to pass through.

[0018] The bottom of the locking pin 2.3 is provided with a bevel 2.31. The inclination of the bevel 2.31 is consistent with the tooth profile angle of the ratchet 2.1. The locking pin 2.3 can engage and be fixed with the ratchet 2.1.

[0019] The counterweight 4 has a fixing bolt on one side and a groove on the other side. The groove has a threaded hole for connecting other counterweights 4. The counterweight 4 can be made of stainless steel and weighs 20~50g. It can be fitted with threaded holes to achieve adjustable counterweight and adapt to the torque balance of users with different hand sizes.

[0020] To assemble this utility model, technicians align the through hole of the chuck 2.5 with the through hole of the ratchet 2.1 coaxially, insert the rotating rod 3, and vertically weld the ratchet mechanism 2 to the top of the power supply handle 1. The rotating rod 3 passes through the through hole of the ratchet mechanism 2, and an internal hex wrench 5 and a socket wrench 6 are installed at both ends and fixed with set screws. A basic counterweight 4 is installed in the threaded hole at the tail of the power supply handle 1, and additional counterweights 4 can be added as needed. The surface of the power supply handle 1 can be covered with an injection-molded layer to increase anti-slip properties. During operation, in the clockwise rotation state, the locking pin 2.3 engages with the tooth groove of the ratchet 2.1 and the entire device is locked. In the counterclockwise rotation state, the locking pin 2.3 slides along the inclined plane 2.31. When the locking pin 2.3 passes the apex of the ratchet 2.1, the spring 2.4 pops the locking pin 2.3 out. Because the vertical handle is close to the horizontal working end, the repeated process can meet the maintenance needs of scenarios such as power equipment and mechanical repair.
