Creation Instructions (2) The inch system is relatively proportional, so please refer to the third picture again, because the moving block (2 1) is a matching ratchet The gear (2 0) is provided, and the detent teeth (2 1 1) are provided for the ratchet teeth (2 0 1) of the ratchet gear (2 0). When it is too small, it will cause the gap between the two to be too large and the meshing tooth surface to be too small. It will only cause the torque value of the entire wrench to be too small, and it will easily cause tooth loss or tooth collapse, and even the number of meshing teeth will also be too small. Too little (on average only 2 ~ 3 teeth are engaged), the torque value will also be insufficient;

Furthermore, as shown in the fourth figure, if the number of ratchet teeth of the ratchet gear (20) is set too much, it will not only cause manufacturing troubles (because its accuracy must be higher), but also because of insufficient tooth thickness. The bite force is not enough, and it is easy to produce slippage. Therefore, the torque value of the entire wrench is too small, so there is room for improvement. In view of this, the author is actively developing research and hopes to create a kind of high torque The value of the ratchet wrench structure can improve the traditional structure on the market and make it more practical. Finally, under the continuous development and research, the creator based on years of experience in manufacturing such products, and finally designed this The created ratchet wrench structure with high torque value can benefit all consumers and the industry.

[Creation purpose of this creation] The main purpose of this creation is to make the ratchet structure of the ratchet wrench the structure with the highest torque value, making it more practical in use; and the secondary purpose of this creation is to enhance the ratchet The degree of engagement with the stopper can make it more stress-resistant; therefore, as a whole, this creation can be said to be quite progressive, and
