The cam assembly (3〇) of the present invention is configured by the abutting member (31) ′ attached to the second arm (21) to engage the cam member (the upper and lower arms (10) 32), the distal cam member (32) is not directly connected to the arm frame, and the abutment structure (31) and the cam member (32) need to be disassembled or replaced when worn. The entire set of components such as the first boom set (1〇) or the second boom set (2〇) may be replaced, or a single component such as the abutting member (31) or the cam member (32) may be directly disassembled, that is, The repair and replacement can be done simply and quickly, and the operation is quite convenient. In view of the high precision required for the curvature of the two-phase abutment surface of the cam mechanism, the rod-shaped abutting member (31) of the present invention is easier to perform precision machining than the conventional boom member having a special profile. No need to use special clips, fixtures, can be 201213192. 佩m Peben, and can turn higher precision requirements, and improve the car brake. Sensitivity and accuracy. Each of the first and second boom sets (10) (20) of the present invention are pivotally connected to each other in a symmetrical manner, and are laterally opened (the set of joint grooves (16) are formed to make the second boom The group (20) can be embedded in a symmetrical state and then pivotally assembled. The structure has two functions: the elastic member (5) on both sides of the elastic member (5) (10) respectively abuts against When the first and second arm (13) (21) correspond to the inner part, the design of the two arms is misaligned with each other, and the structure is not inclined, and there is a car. ±return effect; secondly, the cam member (32) is disposed on the first boom set (10) and the brake set (10) disposed on the second boom set (10) does not present a misreading n That is, each of the fixed (41) and the perforated (324) relative positions are on the same axis, and the cable (42) is in a straight state without bending, so that the cable (10) can be made Increase the efficiency of the car. The brake structure of the present invention is simple and easy to assemble, and can achieve high saki value at low cost; and the 'this hair _ car has a high degree of flexibility, and the safety of riding is also improved. In combination with the above-mentioned "The invention", the "Cam-type self-propelled clipper structure J' system provides a C-clip 4-car structure with high sensitivity and better braking and rebound reversion performance, which will utilize Tim. The design of the abutting abutment cam group is easy to perform precision processing, and the special clamp and the jig can be used to effectively reduce the cost, and the accuracy of the brake can be improved, and the sensitivity and precision of the brake are improved. The two sides of the spiral arms are symmetrically embedded with each other, so that the elastic members can be slanted, and the cam members and the cable locating members are in a non-displaced coaxial state, and the 201213192 lifts the revolving and material efficiency.
