FIG. 3 is a schematic view showing a first embodiment of a reciprocable open plate hand and a fastener (nut) according to the present invention. The orphan mask of the convex orphan plane 232 has a center, and the height difference between the center of the convex curved surface 232 and the midpoint of the bottom surface 24 is η, and the width of the working area is S, wherein s and Η satisfy the following relationship: 29% S < Η < 58% S. When the height difference Η is in the above range, the user can drive a fastener in the clockwise direction. Otherwise, when the wrench is turned counterclockwise, the wrench can be idling back and the fastener is not driven. Next, please refer to FIG. 4 to FIG. 7 ', which is a schematic view showing the state of use of the first embodiment of the reciprocable open-end wrench of the present invention. Referring first to FIG. 4, an external fastener is placed in the working area, and the two opposite sides are respectively engaged with the first clamping surface 2 ι and the second clamping surface 231 and one of the fasteners has a diagonal end and a bottom surface. 24 points of contact. Then, please refer to FIG. 5 'When the clockwise direction is pulled, the first and second clamping faces 211 will also give the fastener a force, wherein the reaction force of the fastener to the block 23 is It is transmitted from the entire convex curved surface 232 to the concave orphan plane 221, and the 8 201010826 2 can resist the moment of the swinging block 23, and the tight_clockwise direction. Referring to FIG. 6, when the counterclockwise rotation is performed, the fastener will give a reaction force to the swinging block 23, so that the swinging block 23 slides along the concave curved surface 221 to the same key position. The device 26, and (4) the village cylinder is made to rotate the first, second = face, and 231 clockwise until the reciprocable open-end wrench i is reversed ten times (four). Thereafter, as shown in Lai 7, the first clamping surface 211 is again engaged with the side surface of the fastener, and the resetting device 26 also pushes the swinging block 23 back into a reset shape, at which time the user can again The hour hand turns the fastener. Month > Figure 8 is a second embodiment of the reciprocating open-end wrench of the present invention. The difference between the second embodiment and the first embodiment is that the lower edge of the swinging block has an extending portion 236, and the abutting portion 25 is disposed at the lower end of the concave curved surface 221 corresponding to the extending portion 236, and The extension can be moved to the top. Referring to FIG. 9 to FIG. 11 , the green display is respectively a third embodiment of the reciprocable _I open-end wrench of the present invention, an exploded view, a schematic view, and a perspective view of the swing block. The second embodiment and the first embodiment have The similarities are not repeated here. The difference is that the convex arc surface 232 of the swinging block 23 is provided with a groove 235, and the concave curved surface 221 of the second jaw 2 is provided with a flange 225, and the radius of the flange 225 is larger than the half of the groove. However, the convex arc surface 232 of the swinging block 23 is equal to the radius of the concave curved surface 221, and further, an inner hole 27 is disposed under the second smear 22, and a complex < 26 26 ′ is installed in the inner hole 2 The lower end of the oscillating block 23 has an extension 236, and the end of the extension 236 is provided for the resetting device 26 to abut. 201010826 In the third embodiment, the through hole and the fixing pin may be modified on the swinging block, and the hollow groove is modified on the flange of the second jaw, thereby preventing the swinging block from being separated from the second jaw . 12 ❿ Referring to Figures 12 and 13, there are shown exploded views and schematic views of a fourth embodiment of the reciprocable open end wrench of the present invention. The difference between the fourth embodiment and the first embodiment is that the resetting device 26 is mounted in the slot 226 below the concave curved surface 221, and one end of the resetting device 26 is further connected with an abutting member 261 for abutting The swinging block 23 is brought closer to the direction of the abutting portion 25. Please refer to FIG. 14, which is a cross-sectional view taken along line AA of FIG. In the present invention, the recess may be a dovetail groove, and the outer shape of the flange corresponds to the groove, and the two may be fitted to each other, thereby preventing the wobble block from coming off the second jaw. In addition, when the groove is a dovetail groove, the wrench can also omit the arrangement of the through hole, the hollow groove and the fixing pin. Referring again to Figure I5, the present invention is shown as a fifth embodiment of a reciprocable open-ended wrench of the present invention. Wherein, in the lower edge of the first jaw clamp 21, there is a rotary groove 212 near the bottom surface, so that when the counterclockwise is turned, the fastener located in the working area has a larger turning space, and the user is more operable. smoothly. Based on the above disclosure, the retractable open-end wrench of the present invention is expected to achieve the following effects: < % The vertical groove and the flange are engaged to prevent the swinging block from swaying upward, so that no additional head is required The cover plate not only embodies the two rams under the armpits, but also has a more conventional cladding structure.
