The pivoting member 2 3 ' of the M349884 combination mainly includes two pairs of locking bolts 2 3 1 , 2 3 2 and Aperture 2 is provided in the axial direction. One of the bolts 2 3 1 of the rod bolt 2 3 2 is provided with a spring 2 3 3 on the pressing member 2 2 and the pressing member 2 2 3 bolts 2 3 1 , 2 1 on the lower side of the joint flange 2 corresponding to the corresponding arrangement of the perforation 2 during the period and the return spring 2 3 3 is appropriate, and the return spring 2 3 3 - 1 below the two sides Combining the flange 2 3 3 3 against the joint section 2 of the plug-in brake handle of the pressing section 2 2, and when the bicycle rider presses the section 2 2 'to make the brake line inner bag and interlocks the brake cable at the other end During the purpose of the vehicle, the pivoting member 23 is made, and when the bicycle rider releases the pressing action on the plate 2, the pressing member 2 can be brought to the unstressed state by the elastic force. 3 3 1 is a return spring 23 3, and the center is set as a screw hole 2311, and the other is a threaded section 2 3 2 1, and the reset bomb is provided in the receiving groove 2 2 3, and then as a pivotal combination, it can be directly The pivots 3 2 are relatively locked from the outer side of the middle portion 222 2 1 1 of the pressing member 22, and the peripheral end 2 3 3 2 of the rod can be placed against the joint The inner top surface of the segment 2 1 1 has the other end 2 accommodated in the inner 2 2 3 , thereby achieving the brake cable which can be pressed against the pressing portion 22 to pull the fixed brake handle 2 2 2 1 The wheel is clamped by the pull clamp, and the brake spring return spring 2 3 3 is subjected to the elastic pressing and the solid type is the I. The handle of the handlebar 2 is 2, the pivoting member 2 is the return spring 2 Therefore, the combination of the support member 21 and the pivoting handle 2 of the pivoting brake member 22 is pivotally coupled to the joint member 2 and the button 3' The bolts 2 M349884 3 1 2 3 2 are respectively provided with a perforation 2 2 1 1 corresponding to the joint between the lower side of the joint member 2 and the lower side of the joint member 2 ^ 1 and the middle portion 2 2 2 of the press member 2 2 2 2 2 1 the outer side is inserted into the relative lock to achieve the purpose of pivoting the joint section 2 1 and the pressing section 2 2, 'however, due to the current bicycle 纟t knife 4 seeking weight reduction, how to put it The weight reduction effect of each component in the bicycle torsion piece is the eager pursuit of the bicycle component manufacturers, and the practice is to make the pivoting member 2 3 bolt 2 3 1 ' 2 3 2 The two screws k 2 3 1 , 2 3 2 must be made of metal material when the lock is applied. Otherwise, if it is made of a plastic material and is locked, the two bolts 2 3 1 , 2 2 is not easy to lock ' and even prone to tooth decay, therefore, the kind of bolts made of metal 2 3 1 , 2 3 2, invisible, except that: the weight of the part is therefore heavier, and Bolt Chuan, "2 in the lock: in the process, must be implemented by other locking tools, also caused, and loaded The complexity is both to be improved. [New content], the creation is based on the shortcomings of the above-mentioned structural shortcomings. The main (4) of this creation is provided. The type of plug-in brake hand can be fixed on the bicycle driver's pipe, or other links. In the car, the end of the tube of the self-holding tube' mainly includes a joint member and a pressing member segment which can be embedded: a joint flange is arranged on both sides of the lower part of the member, so that the front end of the pressing member is divided into a pair of inner sides, The joint flange of the joint member and the middle portion of the pressing member are combined with the punching hole, and the joint member and the pressing member are combined with the joint member, wherein the positioning pin having the smaller rod diameter is provided 7 • M349884 is made of elastomer, which is provided with a positioning ring in the axial direction. When a set is placed on the circumference of the positioning ring and the pressing member is to be combined, the perforation of one side of the connecting flange can be placed on the pressing member. The positioning in the groove, the perforation, is finally passed through until the coupling member passes through the axial direction of the positioning ring without falling off, and can be easily assembled without being locked as required, and the positioning pin can be more easily Change the effect of plastic weight. [Embodiment] The return spring is placed on the inner edge of the receiving groove of the pressing member, so that the coupling member directly engages the positioning pin of the pivoting member, and is perforated through the pressing member, and passes through the axial direction of the receiving ring. The perforation is provided, and when the pressing member is pierced on the other side, the 'positioning pin hole of the pivoting member' can be pivoted by the elastic member and the bolting member of the pivoting member. The connection material is made to achieve a way to reduce the parts description. After each violation, the inspection is provided. Please refer to the fifth, sixth, seventh and first insertions.
