One end of the crucible rotates in the forward direction (as shown by the solid line in FIG. 6), and since the inner tooth portion of the ring body 31 is engaged with the first tooth portion 231 of the block 23, the shaft seat 21 together with the positioning cover 10 and the hand wheel 40 Being driven to provide the power to rotate the drive wheel 5, M407736 • If the drive rod 32 is held to rotate the ring body 31 in reverse (as shown by the dashed line in FIG. 6), the inner tooth portion 311 of the ring body 31 will push against the card. The first tooth portion 231 of the block 23 receives the first tooth portion 231 of the block 23 by the end of the first tooth portion 231 of the block 23 due to the end of the concave curved surface 234 of the block 23 being pushed against the top member 2233 at the same end. After the inner tooth portion 311 of the body 31 is pushed up, the concave curved surface 234 end of the block 23 will abut against the abutting member 2233, and the first tooth portion 231 of the block 23 is separated from the ring body 31. The portion 311, so that the ring body 31 and the transmission rod 32 can be repositioned with respect to the shaft seat 2 in the reverse φ direction, so that the reciprocating oscillating transmission rod 32 can cause the wheelchair to move toward the front, and because of the transmission rod 32 Having a longer force arm provides the user with a labor-saving operation effect; please refer to FIG. 7 , when the user wants to operate the wheelchair to move backward, the operation block 222 of the rotation button 22 is rotated to reach the top. The piece 2233 is rotated to push against the other end of the concave arc surface (10) of the block block 23. Since the other end is located at the same end as the second tooth portion 232, the second tooth portion 232 is engaged with the inner tooth of the body 31. In the portion 311, at this time, the transmission rod 32 is rotated by the hand and reversed (as shown by the broken line in the spring), since the second tooth portion 232 and the inner tooth portion 311 of the ring body W are engaged with each other, the shaft seat 21 together The positioning cover and the hand wheel 40? belt pull, and then provide the driving wheel 5 〇 rotation power, and vice versa, the operation drive 32 to make the bad n 31 forward (shown in the solid line in the figure), then the ring body w邛311 The second tooth portion 232 of the block 23 is pushed against the top member 2233 and is separated from the ring body 31. The tooth portion 311, so that the ring group/and the transmission pedestal 32 can be rotated and rotated relative to the shaft seat 21, so that the swinging transmission lever 32 can be used to move the wheelchair toward the rear. Month/See Fig. 8, which is a second embodiment of the present invention, which differs from the first embodiment of the present invention in that the outer surface of the ring body 3, a of the movable member 30A is combined in a plurality of annular arrangements. The transmission rod 32A; in the second embodiment of the present invention, in the actual use, the transmission rod 32A does not extend over the outer edge of the driving wheel 50A, and pushes the transmission rod 32A by hand, which can drive the hand pushing wheel and the driving secret 50A to rotate. The second embodiment of the creation creates a wheelchair for the purpose of moving by continuously pushing the transmission rods 32A. Referring to FIGS. 9 to 11, a third embodiment of the present invention is different from the first embodiment in that: the joint portion 12B of the positioning cover 彳0B includes a plurality of extension plates spaced apart from the periphery of the substrate 11B, and And a plurality of positioning plates on the extension plate, wherein the outer side surfaces of each of the extension plates are provided with at least one radial limiting hole 1 21 B extending through the inner side surface, and an end surface of each extending plate is provided with a socket, 22B. The socket 1 22B and the limiting hole 121 B are in communication with each other. Each positioning plate has a radial insertion plate 123B. The insertion plate 123B is provided with at least one fixing hole 1231B. The end of the insertion plate 123B is formed toward the inner side. - a plate 124B, the card plate 124B is curved toward the inner surface of the insertion plate 123B, and the positioning plate is inserted into the insertion hole 122B of the extension plate with one end of the insertion plate 123B away from the card plate 124B, so that the insertion plate 123B is fixed. The hole 1 231 B corresponds to the limiting hole 1 21 B of the extension plate, and the locking member 125B is respectively inserted into the limiting hole 121B of the extension plate and coupled to the fixing hole 1231B of the corresponding insertion plate 123B, and the locking piece 125B The end is pressed against the extension plate to position the extension plate and the positioning plate In the third embodiment of the present invention, the first operation of the lock 1B is loosened on the extension plate, so that the positioning plate can slide the insertion plate 1 23B relative to the position 10 M407736 in the insertion hole 122B of the extension plate.
