When the second card end (52) is correspondingly engaged with the first card f end (41), and when the base block (51) is located at the release position, the second card is enabled. The end (52) and the first card end (41) are separated from each other. The limiting portion (60) has three first-slot-shaped grooves (four) which are respectively recessed on the inner annular surface of the base block (four) and extend in the axial direction to the axial direction of the base block (51). The end end faces, the three second strip-shaped grooves (62) are respectively recessed on the shaft body (31) and extend along the shaft axis by an appropriate length, and respectively correspond to a first-shaped strip feeding (61). A plurality of card beads (63) are placed in a separate position - the corresponding first- and second strip-shaped recesses (61) (6·, which limits the second card portion (9)) are only axially slidable on the rotating body (10) It is impossible to rotate in the radial direction. The elastic portion (70) has two positioning ring bodies (71) (72) coaxially screwed to the shaft body (4) and is open to the second card portion (50), and an elastic body formed by a spring. (The paste is sandwiched between the second card portion (4) and the adjacent positioning ring body (71) for providing elastic force for the second card portion to be elastically located at the latching position. The hunting is composed of the above components. The torque limiting structure (1〇) of the transmission member may be bridged between the first and second transmission ends (23) (34) by the power between the workpieces, and the rotation action of the power riding output is transmitted through the first transmission end (23) driving the second transmission end (34) to rotate synchronously through the _th and second card portions _〇 in the state of the cassette, and the torque of the #力力第__ transmission end (23) When the value of the excess force (10) is provided, the second card portion (4) is moved from the position of the card to the release position, so as to interrupt the linkage of the first and second transmission ends __ The purpose of protecting the workpiece is achieved. 200815162 In addition to the actuating method, there should be two explanations, one of which relates to the ratchet shape of each of the second card ends (41) (52), which can be adjusted according to the needs of actual use. If the abutting end faces of the first and second latching ends (41) (52) are in a right angle form, the output of the full torque can be reversed in the reverse direction without limitation, so as to respond to the snail The need for the operation of the cap loosening, it is easy to say, that is, the design of the shape of the card on the end of the card should be a standard of the prior art, and all the equivalent technologies before the application of the case should be able to The scope of the culling is determined by adjusting the elastic value provided by the elastic portion (70). In this embodiment, the position of the two positioning ring bodies (9) (10) is changed to change the second card. The distance between the portion (10) and the adjacent positioning ring body (9) is adjusted to adjust the state of the elastic body (73) to be compressed, thereby achieving the purpose of adjusting the torque limit value. Referring to the fifth and sixth figures, the torque limiting structure (ΐσ) of the transmission member provided in the second preferred embodiment of the present invention is substantially configured in the foregoing preferred embodiment. The same is the same as the 'different is the implementation of the shot, the majority of the disk-shaped turns of the opposite side of the celestial axis is formed into a body (73'), to elastically the first: the card part (5σ) Maintain the card on the stand. "Monthly" is not shown in the seventh embodiment of the present invention. The torque limiting structure w (1G) of the transmission member provided in the third preferred embodiment of the present invention is similar to that of the above-mentioned f-best paid towel. The difference between the second transmission end (34") in the embodiment is a hexagonal concave hole, and the coaxial recess is disposed on the other end of the shaft of the shaft, so as to be suitable for (four) The person. change. By the second and third ___, the composition of the elastic portion provided by the present invention and each of the transmissions are both entitled, and therefore, the change of __容容 is also based on The range of the obtained culvert. 9 200815162 BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is an exploded perspective view of a first preferred embodiment of the present invention.
