And being combined with screw between described body, described body is provided with fixing described movable hanging at right end position
First screw of arm, described movable arm is provided with rotating seat, described rotation away from that one end of described body
The left end of swivel base has the first card, and the right-hand member of described movable arm is provided with the second card, described first dish
It is combined with bolt between face and described second card, in described rotating seat, is provided with hanging wheel, described hanging wheel and institute
Stating and be combined with rotary shaft between rotating seat, described structure keeps the lower end of set to be provided with the first ring portion, described rotation
The bottom of swivel base is provided with the second ring portion, is combined with safety rope between described first ring portion and described second ring portion.
Preferably, described body and described movable arm are steel, and the wall thickness of described body is 10mm-25mm,
The wall thickness of described movable arm is 8mm-16mm.
Preferably, the position, outer ring of described movable arm arranges annular and is provided with the gib block of more than,
Described gib block is axially arranged, and the inwall of described body is provided with the gathering sill coordinating described gib block.
Preferably, described bolt that part between described first card and described second card is overlapped
It is provided with spring.
Preferably, described safety rope is steel wire rope.
The beneficial effects of the utility model are: this device uses the form that body and movable arm coordinate, when this
When body or movable arm bend, movable arm cannot normally bounce back to internal, reminds user pair
Damage parts are replaced, it is to avoid cause security incident, and this device can need regulation to live according to suspention simultaneously
Dynamic arm and the cooperation position of body, meet and use needs, can play protected effect by safety rope, when
When movable arm fractures, the goods of institute's handling can be avoided directly to land by safety rope, this device
Structure is relatively simple, and cost is the cheapest, is suitable for promoting the use of.
