Problems solved by technology

If the second slot 15 is not processed for the second time, the detent 16 in the slot 15 will not be able to move smoothly, and the detent 16 will easily cause jamming and failure.
Moreover, the conventional ratchet driver only utilizes two detents 16 to engage, and the detent force is relatively small. If the detent 16 and the teeth are rotated under high torque, slipping or chipping of the teeth is likely to occur between the detents 16, resulting in Fault, it can only withstand small torque turning, not suitable for professional use, not easy to use, practical
The various deficiencies derived from the existing ratchet screwdrivers really need to be developed and improved.

Abstract

The ratcher screw drive has the first body with two containing sections and for clamping parts teethed with at least two clamps teething with the teeth of the second body, with two times clamping force of the existing structure, strong in clamp force, bearing high torque, difficult for slippery or teeth broken. Two container parts horizontally going through the first body, using the long mold core of the male die crossing the mold cavity to form the said two container part, with the said mold being able to clamp inside the mold and steadily positioned inside the cavity, without manufacturing tolerance, very practical, with advances in design.

Description

technical field [0001] The invention relates to a ratchet screwdriver, in particular to a ratchet screwdriver with high torque and easy manufacture. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , and effectively reduce costs in order to survive under the test of fierce market competition. [0003] Referring to Annex 1, it is the U.S. Patent No. 6,047,802 "RATCHET DRIVING MECHANISM" patent case. One side of the pivot seat 1 has two hollow slots 15 to the outside, and the two slots 15 are respectively inserted into the latches 16. The two detents 16 are pushed outward by the springs 17 respectively disposed in the slots 15 to engage with the teeth of the combination body 3 . However, durin...
