Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment 1
The present embodiment provides brake shoe drill provision for disengagement, and as depicted in figs. 1 and 2, it includes support, arm-tie 1, a pair of links 8
With a pair of cranks 7, two cranks 7 are symmetrical to be hinged on the bracket.The support includes support card-tight part 4, branch
Frame limiting section 10 and support supporting part 11, the top of support card-tight part 4 offer U-shaped opening groove 3, the support limiting section 10
On offer arm-tie stopper slot 13, the motion of arm-tie 1 is arranged in the arm-tie stopper slot 13, and the top of arm-tie 1 opens up
There is brake shoe drill running-on 2, the bottom symmetrical of arm-tie 1 is hinged with two connecting rods 8.The crank 7 include the long pommel 71 of crank,
Crank short handle end 72 and crank flex point end；Two cranks 7 are hinged on institute by the way that the crank flex point end is symmetrical respectively
State on support, two crank short handle ends 72 are respectively hinged at the other end of two connecting rods 8.
In order to prevent the arm-tie 1 from skidding off the arm-tie stopper slot 13 in motion process, on the support limiting section 10
