In the spherical locating slot of position block 4 and outer pulley locating piece 10 composition；In outer pulley part, rope sheave 6 is enclosed within bearing 5,
5 sets of axle shape position portions in outer pulley locating piece 4 and outer pulley locating piece 10 of bearing, cotton rope 6 is wound on by rope sheave
Groove on 7 and the groove on position-limited wheel 19, the wire casing being made up of the groove on the groove on rope sheave 7 and position-limited wheel 24
Interior slip；In sprung parts, pulley sleeve Positioning screw 9 is connected with pulley sleeve 8 with screw thread, and pulley sleeve Positioning screw 9 is outside simultaneously
Slide in the exterior annular groove of pulley locating piece 4 and outer pulley locating piece 10, connecting rod 18 is enclosed within connecting shaft 13, peace
It is contained in the arcuate groove of pulley sleeve 8, then check lock lever 15 is enclosed within connecting shaft 13, spacing with attaching nut 14, with alignment pin 17
Connecting rod 18 and locking nut 16 are slidably connected, spacing, with locking nut 16, connecting rod 18 is threadeded with check lock lever 15
To together；Position-limited wheel 19 is connected with pulley sleeve 8 by limit shaft 20, and spacing with split pin 21, and position-limited wheel 24 passes through limit
Position axle 23 is connected with pulley sleeve 8, and spacing with split pin 22.
The invention has the beneficial effects as follows being slided it is ensured that inside and outside by universal relative between spherical interior pulley and outer pulley
Pulley changes the direction of power in spacial multi-angle, and then reaches using multi-angle change, makes high building outdoor construction hanging basket space bit
Put and be able to both horizontally and vertically arbitrarily adjusting；Rope sheave wire casing and spherical structure cooperation in outer pulley, and pulley sleeve and outer cunning
It is ensured that during angle change, cotton rope will not take off groove and self-locking for the cooperation of wheel cannelure；Meanwhile, the arc groove of pulley sleeve
Cooperation and sprung parts between is it is ensured that suspender vertical.
