Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not paid
Embodiment, belongs to the scope of protection of the invention.
Anti-fall detacher shown in Fig. 1-9, including upper boom portion 1, rotation are installed on the first shackle 2 of the upper end of upper boom portion 1, turn
Dynamic the second shackle 3 for being installed on the lower end of upper boom portion 1, is fixedly installed in the electromagnetism elevator 4 in upper boom portion 1, and upper end rotates installs
Lower arm 5 in the second shackle 3, lower rotational is installed on the suspension hook 6 at the lower end of lower arm 5, one end is hinged with lower arm 5,
Swing rod 7 for locking suspension hook 6, the locating part 8 for being arranged on lower arm 5, being rotated up for spacing swing rod 7, and connection
