Figure 5 is a cross-sectional view of a second preferred embodiment of the present invention, wherein the second card portion is located at the click position. 1320736 is a cross-sectional view of a second preferred embodiment of the present invention, wherein the second card portion is located in the release position. Figure 7 is a cross-sectional view showing a third preferred embodiment of the present invention. First, referring to the first to fourth figures, in the first preferred embodiment of the present invention, the torque limiting structure (10) of the transmission member is provided by a first transmission portion (2〇), a second a transmission portion (30), a first card portion (4〇), a second card portion (5〇), a limit rotating portion (6 (7) and an elastic portion (7〇). The first transmission portion ( 2G) has a substantially columnar body (21), and the __shaft hole (4) is disposed in the column axis direction of the body (21), and the first transmission end (23) of a quadrangular concave hole is coaxial Extending from the end face of one end of the column shaft of the body (21), an annular shoulder surface (4) is disposed on the hole wall of the shaft hole (22), and faces the first The position of the transmission end (23). 4 - the transmission part (3 has a columnar shaft (4) of appropriate length, one end of the misalignment shaft is coaxially connected to the shaft hole (22), an annular bead groove (32) is disposed on the circumferential side wall of the shaft end of the shaft (four) and corresponds to the shoulder surface (24). A plurality of bearing balls (4) are accommodated in the tree groove (32) and the shoulder surface ( 24), so that the shaft (31) and the body (21) form an appropriate The bearing structure is adapted to rotate relative to each other, and a quadrilateral columnar second driving end (34) is coaxially protruded on the other end of the shaft shaft of the shaft (31). The first card portion (40) is a plurality of ratchet teeth disposed on the other end of the column shaft of the body (21), thereby forming a first latching end (41). The second card portion (5〇) has an annular base block (51) a coaxial sleeve is disposed on the shaft (four) and faces the first-card portion (four) with the side surface of the shaft, and is reciprocally displaceable along a shaft of the shaft (8) between a palm and a release position, and a plurality of ratchets The tether is disposed on one of the side ring faces of the base block (51) for forming a second latching end (52), and when the base block (51) is located at the latching position, the second card is caused The rear end (52) is correspondingly engaged with the first end (41), and when the base block (51) is located at the top position, the first card end (52) and the first The 掣 end (41) is separated from each other. The limiting portion (60) has three first-slot-shaped grooves (61) which are respectively recessed on the inner annular surface of the wire (four) and along the axis Extending through to the axial end faces of the base block (51), three second strip-shaped recesses (62) They are respectively recessed on the shaft (31) and extend along the shaft axis by an appropriate length, and respectively communicate with a first strip-shaped groove (61), and a plurality of card beads (four) are respectively embedded in a pair of corresponding ones. A second strip-shaped recess (61) (62) 3⁄4 for restricting the second latching portion (9) from sliding in the axial direction on the shaft (31) and not being rotatable in the radial direction. The part (10) has two positioning ring bodies (Μ?2) which are coaxially screwed to the shaft body, and are interposed with the first: card portion (5__, the elastic body (73) formed by the rotating spring Between the first card, P (5G) and the similar positioning ring body (71), the 贱 provides elastic force to elastically position the second cardinal. The torque-constrained structure (10) of the transmission member may be bridged between the power source and the turntable by the first and second transmissions (34), and the rotation of the output of the power source may be The first transmission end (23) passes through the first and second card portions in the state of the cassette () (4) the first transmission end (3 steps are performed, and when applied to the first transmission (23) When the torque value exceeds the elastic force provided by the elastic portion (7〇), the second card portion (5〇) is moved from the card engine position axis to the release position, so as to interrupt the first and second portions. Drive China) _ The linkage of 'to protect the red pieces. In addition to the above-mentioned actuation mode, there should be two explanations, one of which relates to the ratchet shape of each of the first and second card end (41) (52), which can be determined according to the needs of actual use. Adjustment, if the first and second card withdrawal ends (41) (52) are in a right angle form at the abutting end _ of the reversing motion, the output of the full torque can be reversed in the reverse direction without adding _. Pu's operation demanders, it is easy to say, that is, the design of the card shape of the card engine should be a standard of the prior art, and all the equivalent technologies before the application of the case should be covered by the invention. The range of the two is to adjust the elastic value provided by the elastic portion (70). In this embodiment, the position of the screw and the position of the two positioning ring bodies (71) (72) is changed to change. The first: the distance between the card portion (5Q) and the adjacent positioning ring body (71) is adjusted to be in a state of being compressed, thereby achieving the purpose of adjusting the torque limit value. Referring to the fifth and sixth figures, the torque limiting structure (10) of the transmission member provided in the second preferred embodiment of the present invention is substantially configured as disclosed in the foregoing preferred embodiment. The same 'different' is for the implementation of the money, which is formed by the majority of the disk-shaped turns of the squaring of the squad, and the elastic body (73) is turned "transferred to the second card portion (10)).掣 Location. Continuing to refer to the seventh embodiment, the torque limiting mechanism of the transmission member provided in the third preferred embodiment of the present invention is: (10), which is similar to the one disclosed in the first preferred embodiment. The difference is that the second transmission end (34") in the embodiment is set to be an edge-shaped recessed hole coaxially recessed on the other end of the shaft of the shaft, so as to fit the workpiece The descriptions of the first and second embodiments of the present invention are related to the design of the elastic portion and the shape of each of the transmission ends. In the case of a change in the requirements of the present invention, the changes in the technical content are also within the scope of the invention.
