The effect of the new type is to be elastically set in the middle of the inner wall of the second floor of the second generation. The left and right positioning grooves are arranged in the side of the reserve, so that the dialing is not swayed and the effect is convenient. [Embodiment] M364578 The following new and other technical contents, features and effects of the following are presented in the following paragraphs: - ^ ^ Chu. In the detailed description of the preferred embodiment of the present invention, reference will be made to the preferred embodiment of FIG. 3, FIG. 4 and the net, the main package: "; this new: switching ratchet wrench in the first - _ ^ 3 wrench body 20, a ratchet single 3 〇 and a direction _ unit 4G, and then, after the combination of the spatial pattern details. The m-thin structure and the wrench body 2 〇 have a 葩轳〇"" head 钿 21, the inside end 21 is recessed with a 4-hole-shaped first chamber 211, adjacent to the first chamber The third recess chamber 213 is formed in the shape of a fixed column hole adjacent to the side of the second chamber 212 - adjacent to the second chamber 212 - and is recessed in an inclined manner in the middle of the wall. There is a receiving hole 214. The wheel unit 30 has a control rod 32 in the center of the driving shaft 31, and a spring 33 which is sleeved on the control rod 32. The latching ball 100 inside the driving head 31, and the latching block 35 disposed in the second chamber 211 adjacent to the driving head 3ι. The driving head 31 is provided with a ring tooth at the outer circumference. The lever 32 is elastically urged by the elastic crest 33 to cause the latching ball 34 to protrude from the outer surface of the square pin portion 312. The latching block 35 is a block having a slightly half-moon shape, and the front side is provided with a ratchet portion (5) The rear side is provided with a resisting recess 352. The latching block 35 is movable in the left and right of the second chamber 2U so that the ratchet portion 351 is engaged with the ring tooth 311. The π singer is elastically disposed at (4) 41 (4), and the elastic directional control unit 40 has a locating member 43 disposed in the accommodating hole 214 by the dialer 41 M364578 disposed in the third chamber 213.
