Description

Lighting devices for hand tools

This invention provides a lighting device for hand tools, in particular, a lighting device that can provide bright light illumination for a preset torque wrench to facilitate scale adjustment. The base and cover of the main body are assembled on the handle of the preset torque wrench, and the light source system assembled on the main body illuminates the scale of the handle with bright light, so as to achieve the purpose of clearly identifying the scale of the handle through the bright light.

According to the regulations, assembly, disassembly or maintenance operations in various technical industries usually require the assembly or disassembly of screws, nuts or other fixed objects such as rivets and pins, that is, various hand tools (such as various open-end wrenches, adjustable wrenches, ratchet wrenches, torque wrenches or screwdrivers) or electric tools must be used to cooperate with the assembly or disassembly operations. Due to the different requirements for the degree of tightness and structural strength required for assembly in various technical fields, various mechanisms, devices or objects must be combined and positioned in an appropriate fixing manner during assembly operations to achieve the completion of the assembly of various mechanisms, devices or objects, which can be used under safety conditions.

However, when assembling various mechanisms, devices or objects, the torque required for locking and fixing is different. If the force is insufficient or too much during assembly, the mechanism or device will be assembled incorrectly, easily loosened or locked tightly, which is not conducive to subsequent disassembly, maintenance and other operations. The wrench, a commonly used hand tool, is one of the commonly used tools for on-site construction personnel because it is easy to carry and use. Among them, the torque wrench or ratchet wrench is the most commonly used tool. The torque wrench or ratchet wrench can be used to adjust the appropriate torque when used. During on-site construction operations, the assembled mechanism or device can be properly locked, assembled, and fastened, which is convenient for on-site construction personnel to adjust and use in response to the assembly of various different mechanisms and devices.

However, currently commonly used mechanical torque wrenches such as torque wrenches or ratchet wrenches are assembled with a torque adjustment drum on one side of the handle. By adjusting the scale on the drum and the torque value scale on the handle, the torque value and torque poundage of the wrench are adjusted through the spring inside the handle or other components. It is convenient for on-site construction personnel to understand the torque data of the wrench by adjusting the alignment scale on the drum and the handle to proceed with assembly or disassembly of the construction work; however, when the construction site is indoors, dark, or must be done at night, During construction work, the scale of the adjustment drum and the torque value scale on the handle are adjusted. Because the construction site is often insufficiently lit, dim, or works at night, it is difficult for on-site construction workers to clearly see the scale of the adjustment drum and the torque value scale on the handle when using hand tools such as torque wrenches or ratchet wrenches, making it difficult to identify the scale or unclear to identify, which can easily lead to scale adjustment errors, failure to adjust to the necessary scale position, or misreading the scale value, etc., which also causes inconvenience in on-site construction work. There are many problems that need to be improved urgently.

Therefore, how to solve the problems and troubles of the torque scale of the currently used torque wrenches or ratchet wrenches, such as being difficult to identify or unclear due to the influence of the environment, and the difficulty in clearly identifying the scale at the construction site in the dark or at night, is the direction that the relevant manufacturers in this industry are eager to study and improve.
