Description

Technical Field

[0001] This utility model relates to the technical field of torque wrench equipment, specifically a multi-functional torque wrench. Background Technology

[0002] A torque wrench is a precision hand tool with torque measurement capabilities. It can precisely control the applied torque when tightening bolts or nuts, playing a crucial role. For example, in the assembly of automobile engines, bolts in different parts need to be tightened to specific torque values. Using a torque wrench ensures that each bolt reaches the specified tightness, preventing loose connections due to insufficient torque that could affect the normal operation and safety of the equipment, while also preventing damage to bolts or connecting parts due to excessive torque, thus ensuring assembly quality and equipment reliability.

[0003] For example, a multi-functional torque wrench disclosed in Chinese patent literature (publication number: CN216913623U) has a handle that slides onto the housing for easy length adjustment; a power supply unit installed on the bottom shell and covered with a power supply cover for easy assembly and disassembly; and a power element that drives the radiator to rotate to accelerate heat dissipation. This multi-functional torque wrench has a compact structure, is easy to use, and is convenient to assemble and disassemble.

[0004] However, this method is only applicable to normal standard fastener operations and has limited functionality. For non-standard fasteners such as hexagonal screws, rusted stuck parts, and irregularly shaped clips, there is a lack of suitable special tool heads and dismantling auxiliary structures. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional torque wrench in order to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional torque wrench, comprising: a wrench handle, a wrench head fixedly connected to the head end of the wrench handle, a sleeve provided at the bottom end of the wrench head, a pry bar movably inserted inside the wrench handle, a handle rod fixedly connected to one end of the pry bar, a protective sleeve fixedly connected to the outer end of the head of the handle rod, a threaded ring fixedly connected to one end of the tail end of the wrench handle, and a support mechanism provided in the middle of the handle rod.

[0007] As a further embodiment of this utility model: a connecting ring is threaded to one end of the handle rod, a small handle is fixedly connected to one end of the connecting ring, and a cross blade is fixedly connected to one end of the head of the small handle.

[0008] As a further embodiment of this utility model: the support mechanism includes a movable sleeve, a support shaft seat, and a threaded rod. The movable sleeve is movably slidably connected to one end of the handle rod, the support shaft seat is rotatably connected to the bottom of the movable sleeve, and the threaded rod is fixedly connected to the middle of the bottom of the support shaft seat; the support outer tube and the foot are also present. The support outer tube is threadedly connected to the outside of the threaded rod, and the foot is fixedly connected to the bottom of the support outer tube.

[0009] As a further improvement of this utility model: the inner wall of the wrench bar is provided with a receiving cavity, the receiving cavity is adapted to the pry bar, and one end of the handle bar head is provided with a threaded ring groove, the threaded ring groove is adapted to the threaded ring.

[0010] As a further improvement of this utility model: a blade-accommodating cavity is provided at the middle of the tail of the handle rod, the cross blade is movably inserted into the handle rod, and the blade-accommodating cavity is adapted to the cross blade.

[0011] As a further improvement of this utility model: a threaded groove is provided at the other end of the handle rod, and the threaded groove is adapted to the connecting ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, rotating the handle separates the threaded ring from the threaded ring groove, allowing the pry bar to be completely extracted from the receiving cavity of the wrench handle. Its own structure or end attachment can directly act on complex fasteners that traditional sockets cannot handle, such as rusted and stuck parts and hex socket screws, breaking through the limitation of traditional torque wrenches that can only handle standard bolts and nuts. When performing operations with higher torque, the movable sleeve is placed on the handle handle and the supporting outer sleeve is rotated, so that the foot is pressed against the working surface to form a triangular stable structure of "handle handle-support mechanism-pry bar", preventing shaking when applying force and improving the operational stability in high torque scenarios. The Phillips head is normally stored in the receiving cavity at the end of the handle handle to save space. When in use, the connecting ring is unscrewed to pull out the Phillips head and the small handle is tightened to use it as a screwdriver. Through the independent function of the pry bar and the storage design of the Phillips head, the functions of torque wrench, screwdriver, and pry bar are integrated into one, reducing the number of tools to carry while flexibly dealing with operations in narrow spaces and diverse fastener needs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 6In this embodiment of the utility model, a multi-functional torque wrench includes: a wrench rod 1, a wrench head 2 fixedly connected to the head end of the wrench rod 1, a sleeve 3 provided at the bottom end of the wrench head 2, a pry bar 4 movably inserted inside the wrench rod 1, a handle rod 5 fixedly connected to one end of the pry bar 4, a protective sleeve 6 fixedly connected to the outer end of the head of the handle rod 5, a threaded ring 7 fixedly connected to one end of the tail end of the wrench rod 1, and a support mechanism 8 provided in the middle of the handle rod 5.

[0018] The inner wall of the wrench lever 1 has a receiving cavity 12, which is adapted to the pry bar 4. One end of the handle lever 5 has a threaded ring groove 13, which is adapted to the threaded ring 7.

[0019] Reference Figure 1 , Figure 3 and Figure 5 The handle 5 has a threaded connection to a connecting ring 9 at one end, a small handle 10 is fixedly connected to one end of the connecting ring 9, and a cross blade 11 is fixedly connected to one end of the small handle 10.

[0020] The handle rod 5 has a blade-accommodating cavity 14 at the middle of its tail. The cross blade 11 is movably inserted into the handle rod 5, and the blade-accommodating cavity 14 is adapted to the cross blade 11. The other end of the handle rod 5 has a threaded groove 15, which is adapted to the connecting ring 9.

[0021] Reference Figure 1 and Figure 6 The support mechanism 8 includes a movable sleeve 801, a support shaft seat 802, and a threaded rod 803. The movable sleeve 801 is movably slidably connected to one end of the outer side of the handle rod 5. The support shaft seat 802 is rotatably connected to the bottom of the movable sleeve 801. The threaded rod 803 is fixedly connected to the middle of the bottom of the support shaft seat 802. The outer support tube 804 and the foot 805 are connected. The outer support tube 804 is threaded to the outside of the threaded rod 803, and the foot 805 is fixedly connected to the bottom of the outer support tube 804.

[0022] The working principle of this utility model is as follows: During use, rotating the handle 5 separates the threaded ring 7 from the threaded ring groove 13, allowing the pry bar 4 to be completely extracted from the receiving cavity 12 of the wrench handle 1. It then acts directly on the target object through its own structure or end attachment, solving the problem of traditional torque wrenches relying on the socket 3 for certain tasks. When using the pry bar 4 for higher torque operations, the movable sleeve is fitted onto the handle 5, and the supporting outer sleeve 804 is rotated, causing the foot 805 to press firmly against the working surface, forming a triangular stable structure of "handle 5 - support mechanism 8 - pry bar 4," preventing overall wobbling when force is applied by hand. This allows for handling situations where the handle is rusted, jammed, or where the socket 3 cannot reach the target object. In cases of improper handling, the pry bar 4 can be used directly. The Phillips head cutter 11 is normally stored in the blade-receiving cavity 14 at the end of the handle 5, saving space. When in use, the connecting ring 9 is unscrewed from the threaded groove 15, the Phillips head cutter 11 is pulled out from the handle 5, and then the connecting ring 9 is tightened onto the small handle 10, which can then be used as a screwdriver. Through the independent use of the pry bar 4 and the storage design of the Phillips head cutter 11, the functions of torque wrench, screwdriver, and pry bar are integrated into one, reducing the number of tools to carry. It breaks through the limitation of traditional torque wrenches that can only handle standard bolts and nuts, and can deal with rusty stuck parts, non-standard fasteners, such as hex socket screws and irregularly shaped clips, and other complex scenarios.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
