Embodiment
Be described in further detail below in conjunction with accompanying drawing 1 ~ 3 pair of the utility model.
Halting mechanism in the present embodiment, the bracing wire comprise the first support 5, fitting together with the first support 5 links up with 1, pedal arm 2, tooth plate 4, unlock drag hook 7, unlock the pull back spring 71 of drag hook, the pull back spring 84 of ratchet 8, ratchet, limiting stopper 3 and parking lamp switch 9.
Support in the present embodiment comprises the first support 5 and the second support 6 with the first S. A. 51, second S. A. 52, opening 53, the 3rd S. A. 55 and parking lamp switch 9, is also provided with positioning plate to ensure reliably to be connected between the first support with the second support at opening 53 place of the first support 5.Be provided with limiting gasket to keep the gap between the first support and the second support between first support 5 and the second support 6, ensure the spacing leaving 12mm ~ 15mm between the first support 5 and the second support 6.First support 5 is also provided with knock hole 54, the second support 6 is provided with the knock hole 54 matched with the knock hole of the first support 5, bolt makes two supports link together by the knock hole 54 of the first support 5 and the knock hole of the second support 6.
Pedal arm 2 to be socketed on the 3rd S. A. 55 and to rotate along the 3rd S. A. 55, pedal arm 2 is provided with the first groove 21 and the second groove 22, tooth plate 4 is provided with the first boss 41 and the second boss 42, first boss 41 is connected in the first groove 21 of pedal arm 2, second boss 42 is connected in the second groove 22 of pedal arm 2, and the unblock drag hook 7 with roller 72, knock hole 73 and drag hook 74 to be enclosed within the second S. A. 51 and to rotate along the second S. A. 51.
First support 5 is also provided with the limiting stopper 3 for spacing pedal arm 2.
Ratchet 8 is socketed on the second S. A. 52 and also can rotates along the second S. A. 52, ratchet 8 is provided with the first grappling fixture 81, second grappling fixture 82 and the 3rd grappling fixture 83, first grappling fixture 81 by the roller 72 unlocked on drag hook 7 and knock hole 73 spacing, second grappling fixture 82 contacts with the tooth bar of tooth plate 4,3rd grappling fixture 83 one end connects one end of pull back spring 84, and the other end of pull back spring 84 is fixed on bracket backing plate by the opening 53 of the first support 5.
