Now further specify structure of the present utility model and working condition by embodiment in conjunction with diagram.

Folded form lifting rotation handy stool folds rotating mechanism, compositions such as tripod lifting self-locking mechanism by movable stool face.Wherein: movable stool face (2), (3) are fixed to the fixedly both sides of stool face (1) by long rivet (11) respectively, and two bench facial plane holddown grooves (4) can pass in and out mobile by the both sides that rivet (5) is respectively fixed to movable stool face (2) and (3).Pull out from the both sides of movable stool face (2), (3) respectively by stool face holddown groove (4) when the stool face flattens and be incorporated into stool facial plane fixed edge (6), make it to produce fixing stool face.Wherein the upper end of the vertical steel pipe of three-legged support (26) is inserted in the lower end of universal joint (22), the groove (23) that ties down universal joint (22) lower end by nut (28) precession screw (27) is located, make it to do universal rotation and can not deviate from, slide block vertical joint (16) is inserted in universal joint (22) upper end, by rivet (13), rivet hole (14), universal joint groove (24) is received on the slide block vertical joint (16), the protruding pin on universal joint both sides (25) ties down the groove on both sides, slide block vertical joint lower end, and the next door is caught on (13) respectively by spring (15) and reached with (25) and vertical the connection make it and can not come off.Also be provided with movable fastening screw (17) on the slide block, wherein: spring (18) the activity orientation plug pin cap (19) of packing into is fixed to slide block (12) top shoe (12) by nut (21) by screw (20) and can parallel turnover moves in the dovetail groove that fixedly the stool face is divided into, when needs are folding, slide block shifted out dovetail trough rim (8) locate to fix by the activity orientation latch.Extracting universal joint (22) makes joint protruding pin (25) leave joint groove (16) just can to make the stool pin folding.After folding, the side of catching on movable stool face (3) by the lock hook (10) that is located at stool face (2) limit, folding tripod lifting self-locking mechanism is by the vertical steel pipe of three-legged support (26), tripod (30), rivet (33), article three, self-locking pin (32), spring compositions such as (34), wherein fix three leg rivet holes (31) on the tripod of five equilibrium (30) and open centre in tripod (30) dead slot both sides, spring (34) pin (32) is connected on the tripod (30) by rivet (33), when the vertical steel pipe of foot support (26) inserts tripod (30) centre bore, when pressure being arranged in the above, the end arm of three following legs is under the supporting of fulcrum at rivet, form lever principle, pin galianconism end just produces above several times toward the power that presses down, pin the vertical steel pipe of foot support (26) tightly, making it can not be toward gliding.When tripod (30) is fallen back on vertical steel pipe lower end (29) when locating, spring (34) catches on vertical steel pipe (29), and three legs just can be up folding parallel with vertical steel pipe around rivet.

The advantage that the utility model compared with prior art has is:

1, the stool face can be amounted to, universal rotation, and self-locking is adopted in the height lifting of stool, and lifting arbitrarily is solid firm.

2, the time spent does not can be folded into shown in (2), and volume is urinated in carrying.
