Description

Ratchet wrench lever positioning device

This creation is about the technical field of hand tools, especially a ratchet wrench lever positioning device that is easy to disassemble and easy to repair.

In mechanical assembly, the ratchet wrench is a commonly used labor-saving aid, especially a hand tool that can be used with different sizes of sleeves to tighten or loosen bolts of various sizes. Because it has the function of unidirectional tightening or loosening the bolt, a lever is usually provided to change or select the direction of the ratchet wrench.

At present, there are many types of commercially available ratchet wrenches. However, the utility model generally cannot be separated from the tool handle, the ratchet device accommodated at the end of the tool handle, the lever for controlling the direction of the ratchet operation, and the end of the tool holder and the cover of the ratchet device. . For example, the ratchet wrench of the new patent case No. 471359 of our country has improved the structure of the tooth-stopping structure, which mainly uses a C-shaped buckle positioning lever, and then uses a cover plate to completely close the ratchet device and the C-shaped buckle to the tool handle. In the end, a complete ratchet wrench is formed.

However, when the lever is shifted in the direction of the ratchet, it will inevitably be rubbed with the pawl of the driving ratchet. Over time, when it is worn to a certain extent, it will definitely affect its operation accuracy and must be replaced. At this time, since the C-type buckle of the fixed lever is completely closed by the cover, it is necessary to remove the cover before replacing the lever, so that the C-type buckle replacement lever can be removed, which is quite uneconomical in time. And when the cover plate is removed, the ratchet device in the ratchet wrench also loses the positioning effect at the same time, which causes troubles in assembly after maintenance, and indeed needs to be improved. Furthermore, the upper half of the lever of the conventional ratchet wrench has a positioning relationship with the tool shank, resulting in uneven force on the upper and lower parts, which is prone to yaw phenomenon and image operation precision.

In view of this, the creator is not easy to repair the above-mentioned conventional ratchet wrench, and must reposition the ratchet device after maintenance, in the spirit of perseverance and excellence. The purpose is to actively research and improve, and through long-term efforts and experiments, finally develop and design this creation.

The main purpose of the present invention is to solve the above problems and provide a ratchet wrench lever positioning device that is easy to disassemble and easy to repair.

Based on the above object, the present invention mainly comprises a cover plate fixed to the working end of the ratchet wrench and closing the working end, the cover plate is formed with a through-class hole having a large diameter section facing outward. An L-shaped lever inserted at the working end of the ratchet wrench, the L-shaped lever extending into the large diameter section corresponding to one end of the cover plate, and forming a ring groove; the ring groove system and the large diameter section are connected to each other And corresponding to the bottom surface of the large diameter section; and a positioning member fastened to the annular groove and accommodated in the large diameter section, one surface of the positioning component is attached to the bottom surface of the large diameter section to avoid the lever from the ratchet wrench In the middle.

With the above-mentioned structural combination, since the large diameter section of the class hole is disposed outward, when the lever is to be repaired or replaced, the lever can be easily removed by directly removing the positioning member from the large diameter section, without The cover is removed, so that the positioning relationship of other components in the ratchet wrench is not affected, and the disassembly is convenient and easy to repair, and the assembly is easy after maintenance. The ratchet device in the ratchet wrench is not required to be repositioned, and the conventional ratchet can be completely solved. The absence of a wrench.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings.
