INSTRUCTION DESCRIPTION (1) TECHNICAL FIELD The present invention relates to a ratchet driver structure, and more particularly to a tool ratchet driver having a directional control structure different from a general starting hand. -Previous technology. At present, there are many kinds of screwdrivers in the city, and the additional functional orientation is generally the most important thing. The 7 k _, 丨, 丄 _ _ T Jit -rtir -M- a t- by field, Small / eight ... ^ 々叨 camel is also different, in addition to the general $ see the screwdriver, there are electronic screwdrivers, magnetic screwdrivers, impact screwdrivers, ratchet screwdrivers, etc., in which the ratchet screwdriver uses the ratchet structure of the way The lifting of the screwdriver has the function of directional control. When the switch is adjusted, the unidirectional and bidirectional swaying can be selected, and the ratcheting screwdriver can only assume an idling state. As described above, please refer to the ninth to tenth drawings, which is a conventional wheel imt system as shown in Fig. 1 with the description of the sleeve, the adjustment ring and the seat body. However, the structure can be $ As mentioned above, there are many difficulties in the process, and it must be done in such a way that the use of this method can be completed. [So, the process is not increased, and the control of its quality is relatively rc-free. The structure is as follows: the structure of the conventional screwdriver is short: low, the bad rate is below - the sleeve part: the conventional ratchet screwdriver is used in the pocket, and the inner center of the inner part is convexly arranged with the ratchet body in the manufacture. It will cause difficulties in its processing. • Shen:: convex cup, this - '戎 ratchet teeth will be hindered by circular bulges, shrinking::, initial: the difficulty of milling and grinding during forming , not only the production time:, mouth:: increase to the structure of the 忒 round bulge, $ Zeng Jia production set: Heyi f and exhibition% process of the non-performing rate page 5

Seat part: a conventional ratchet screwdriver is placed on the seat body so that the swaying block can be placed thereon. A small convex axis is integrally formed at an appropriate position on the space of the valley. 'In order to enable the swaying block to pass on the convex axis; however, it is not difficult to form the initial embryo of the convex axis', but the processing in the narrow space of the seat also produces the same problem as the above-mentioned casing in the manufacturing process. It is not easy to control the structure of its non-performing rate, and there are improvements. a
