Description

Hoist head ratchet wrench structure

The design of the hoist head ratchet wrench is mainly applied to the ratchet wrench technology which can be operated by one hand, fast locked and easy to assemble and repair.

According to the conventionally used ratchet wrench, when the screw is tightened, the ratchet wrench must be continuously pulled until the screw is tightened, which is time consuming and labor-intensive, which increases the trouble and inconvenience in operation, and the existing solution remains to be solved. One of the problems and missing.

Moreover, the conventionally used ratchet wrench has many components, is difficult to assemble and disassemble, and is difficult to maintain; it is the second problem that remains to be solved.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and actively engaged in the spirit of innovation and improvement in response to the existing problems and lack of traditionally used ratchet wrenches. The completed hoist head ratchet wrench structure .

The new technical solution for solving the problem and the effect of the prior art are as follows: the head of the body is provided with a ratchet head, a snap block, a cover plate and a dial, and the ratchet head and the click block are provided with a corresponding ratchet and The ratchet teeth are pulled by the dial button to the left or right, so that the ratchet of the card block produces a one-way card for the ratchet wheel, wherein the ratchet head is further provided with a runner, the runner It can be operated by the index finger and thumb of one hand and quickly rotate the ratchet head locking screw at the beginning of locking the screw; it has an improvement in efficiency and is the main purpose of its achievement.

The technical means applied by the new problem solving 2 and the efficacy of the prior art are as follows: the head of the body is provided with a ratchet head, a latching block, a cover plate and a dial, and the ratchet head and the latching block are provided with corresponding ratchets and The ratchet teeth are pushed to the left or right by the dial button, so that the ratchet teeth of the card block produce a one-way card for the ratchet wheel, wherein: the ratchet head has a groove and is used as a buckle For the purpose of the buckle, the buckle can be easily assembled or disassembled, and the ratchet head can be easily assembled or disassembled. In addition, a through hole and a coupling groove are provided in the middle of the buckle block, and the through hole can be used for fixing the tip. The coupling groove can be integrated with the dial button, and only needs to insert or withdraw the fixing tip, that is, the card block and the dial button can be easily assembled or disassembled, and at the same time, the parts can be reduced, the cost is reduced, and the maintenance is easy; The promotion of the above, the winner of its secondary purpose.
