Detailed description of the invention
As shown in Figure 1, the utility model comprises the first standpipe 1, the second standpipe 2, the 3rd standpipe 3, catch gear and folding joint, the second standpipe 2 is placed on the first standpipe 1 outside, the first standpipe 1 and the second standpipe 2 sliding block joints, catch gear is arranged at the second standpipe 2 tops, and the second standpipe 2 is connected by folding joint with the 3rd standpipe 3, catch gear comprises permanent seat 4, bolt 5, nut 6, retaining washer 7 and eccentric shaft clamp handle 8, permanent seat 4 is fixedly connected with the second standpipe 2, bolt 5 two ends are through permanent seat 4, bolt 5 one end are threaded with nut 6, and bolt 5 other ends are connected with eccentric shaft clamp handle 8 axles through retaining washer 7, folding joint comprises the first joint, second joint and lockable mechanism, and the first joint is fixedly connected with the second standpipe 2, and second joint is fixedly connected with the 3rd standpipe 3, and the first joint and second joint are hinged, and lockable mechanism is arranged on second joint, lockable mechanism comprises V-type locking hook 9, rotating shaft 10, hook retracing spring 11, locking bolt 12, eccentric shaft locking handle 13, locking packing ring 14, packing ring retracing spring 15, setting nut 16, V-type hook is connected in the inside face of second joint by rotating shaft 10, hook retracing spring 11 one end, hook bottom are fixedly connected with, hook retracing spring 11 other ends are fixedly connected with the 3rd standpipe 3, locking bolt 12 one end are threaded with setting nut 16 through rotating shaft 10 centers, the other end of locking bolt 12 is connected with eccentric shaft locking handle 13 axles through locking packing ring 14, packing ring retracing spring 15 is socketed on locking bolt 12, packing ring retracing spring 15 is arranged between rotating shaft 10 and packing ring, the second standpipe 2 is socketed a locking handle geometrical clamp 17.
The working process of this example: locking is eccentric shaft locking handle 13 is rotated to the position vertical with the 3rd standpipe 3 around the shaft from free position immediately, the first joint and second joint are fastened, now V-type hook 9 catches on the first articular surface under the thrust of hook retracing spring 11, standing in one-level lockup state, again by eccentric shaft locking handle 13 around the shaft 10 rotation as for the 3rd parallel position of standpipe 3, now, standing in secondary lockup state, finally with locking handle geometrical clamp 17, eccentric shaft locking handle 13 is fixedly prevented to it gets loose;
When release, eccentric shaft locking handle 13 is rotated to the position vertical with the 3rd standpipe 3, then by V-type hook 9 to pulling away from standpipe direction, now can be to folding vertical vertical release;
While needing to adjust vertical height, eccentric shaft clamp handle 8 is rotated to state as shown in figure mono-, and catch gear release, advances the first standpipe 1 or pull out, adjust behind position 180 ° of eccentric shaft clamp handle 8 left-hand revolutions, now catch gear is in locking state.
