The escaping basin is detached from the axial direction of the transmission portion (21).藉 By means of the above-mentioned member 'the one end edge of the positioning ring (9) abuts against each of the ratchet blocks (32)-side edge surface to block it from being disengaged from the axis direction of the transmission portion (2)) to achieve stable stability The effect of the positioning effect, so the overall structure can be convenient and practical. In order to provide a step-by-step understanding of the characteristics of the creation, the use of technical means and the effect achieved by the righteousness, the financial formula is described as follows: The group 5 of this creation 'firstly sets the ratchet ring (31) to the screw In the connecting portion (11), each of the ratchet block (32) and the cymbal piece (33) is respectively disposed in the ratchet tooth (22) and the reed groove (10), and at this time, each of the first and second portions The positioning groove (41) (43θ) corresponds to the groove of the two; finally, the positioning ring (44) is simultaneously sleeved in each of the first and second positioning grooves (41) (43), that is, a simple step The assembly is complete. Referring to the third to fourth figures, the positioning collar (9) is embedded in each of the first and second single grooves (8) (43), and the end edges thereof are respectively abutted against the respective ratchet blocks. (10) and W(3)), and the tilting (44) is provided at the outer end of each of the ratchet block (32) and the reed (10), so that in addition to reading each of the ratchet block (10) and the reed (33), each of the spines The axially open portion of the tooth groove (22) and the reed groove (10) is separated from the rotation operation of the gaunting range on the outer (each) _ _ (10) _ granule ring (10). t ratcheting drive, mainly the _ the transmission part (8) is worn in the spine ¥ (31), and the step of each of the ratchets (321) (Qingtong (four) connected to the slot 2 of the basin (311), by means of effective transmission of each of the ratchet ring (31) and the wheel (10) synchronous rotation; please refer to the fifth figure, is the effective work of the transmission state, at this time each of the spine w (321) ( 322) her clockwise rotation, that is, the direction in which the vehicle body advances, so that each of the _(10)) (322) can be retracted to the cogging (10) in two parts) (from the animal (31) and When the wheel is compared with the reference to the H-scale, it is ineffective for the Wei state. At this time, each === rotates clockwise and cannot be effectively driven with each of the slots _ ..., although it is the active part of the transmission M384119 The part (21) rotates the 'receiver's seat (10)> in the clockwise direction and the ratchet ring (31) does not move, so the rear wheel does not retreat; on the other hand, the transmission part of the active part (2) ) does not move 'though the rest of the seat (10) and the ratchet ring (8) rotate counterclockwise, that is, the car body forward direction, this time is an idling situation, that is, the inactive transmission shape S 'does not work In the vehicle body, each of the ratchets (321) (322) faces each of the slots (3H) of the rotation t, and then detaches from the toothed portion of the slot (3 (1) side. Group (4〇), in order to solve the conventional "multi-piece" rebound ratchet structure is easy to be loosened or displaced by the open groove end, especially the creation of the positioning edge (42) and the second positioning groove (43) is integrally formed on the side of the ratchet block (32), so that the integral member can be simplified, and the positioning ring (44) is directly sleeved in the assembly to complete the 'exemption calibration operation, so the assembly It is quite fast, which can save man-hours and manufacturing costs. Moreover, the embedded contact area of the positioning ring (44) and the second positioning groove (43) is small, which makes the rotation of the ratchet block (32) more sensitive. Therefore, it is not easy to generate a toothed condition; in addition, the positioning ring (44) blocks each of the ratchet block (32) and the spring # (33) from the (four) side, so that the member can be lowered from the transmission portion (21) The opening end is disengaged or displaced, which affects the transmission effect. This creation uses a "multi-piece" rebound structure combined with a "double-tooth" ratchet block (32). The ratchet block (32) is provided with two ratchet teeth (321) (322) at the twisting end, and can be simultaneously coupled to the tooth groove (311) at two locations, thereby increasing the ratchet ring. (3丨) The contact area of the inner tooth groove (321) (322) to achieve a better transmission effect. It is worth mentioning that the positioning ring (44;) of the present invention may be closed or may have a gap of 10 M384119 The application of the elastic ring body, such as the c-type buckle, is convenient for the structural compatibility of the position groove (9) (10). The "wheel shackle ratchet structure" disclosed by the actual capture The trm money pair (9) is in the position of the squad, and the locating ring of the corresponding position is set on the locating ring, and the positioning ring can be quickly set up without the alignment action.
