71 upper end is equipped with the convex block 73 that buckle is matched with hanging ring 5；The lower end and the touching of 31 phase of block for contacting bar 72 can make buckle
Bar is detached from hanging ring；The angle for buckling bar 71 and contacting between bar 72 is obtuse angle, and touch contact bar convenient for block sticks up bar is buckled
It rises and is detached from hanging ring.
Fixed arm 3 includes fixed ring 32, fixed plate 33 and adjusting rod 34；The upper end of fixed plate 33 is solid with 32 phase of fixed ring
Fixed, lower end is fixed with 34 phase of adjusting rod；Sleeve 2 is penetrated in fixed ring 32 and is mutually fixed therewith, fixed ring be equipped with for set
Mutually fixed first bolt hole of cylinder, fixed plate 33 is tightly attached to the side of 2 outer wall of sleeve, for mutually consolidating fixed arm with sleeve；
Strip-shaped hole 35 is vertically offered on adjusting rod 34, block 31 is fastened by bolts in strip-shaped hole 35, passes through upper downward
Save position of the block on adjusting rod, the critical load amount for being be detached from conducting wire is arranged, position more down, the load that conducting wire is born
Lotus amount is bigger.
Sleeve 2 includes cylinder 21, flange 22 and protruding rail 23；The bottom of cylinder 21 is equipped with outer for making the lower end of davit stretch out
The through-hole in portion；Flange 22 is fixed on the top of cylinder 21, and flange is equipped with the second bolt hole, and cylinder 21 is by flange 22 and fixes
Arm 3 and 1 phase of end cap are fixed；Protruding rail 23 is fixed on the inner wall of cylinder 21, and is vertically extended；The quantity of protruding rail 23 is two
Item, and it is symmetrically disposed on the inner wall both sides of cylinder.
Davit 4 includes sliding plate 41 and connecting pole 42；The edge of sliding plate 41 be equipped with 23 matched groove 43 of protruding rail, be used for
Limitation davit is only capable of vertically for linear motion relative to sleeve, cannot rotate, to ensure that fastener is directed at gear always
The position of block 31；Elastic device 10 is compressed between sliding plate 41 and the bottom of cylinder 21, and sliding plate is used for elasticity of compression device；Even
The upper end and 41 phase of sliding plate for connecing column 42 are fixed, and lower end is equipped with thread head, and is threadedly coupled with hanging ring 5 by thread head.
