Oscilaltion axle, described support arm can be rotatably set on oscilaltion axle, and described oscilaltion axle upper end is provided with rotary stopper lid, and oscilaltion axle lower end is arranged with elevating mechanism, and side is provided with oscilaltion locking switch, and elevating mechanism has positioning sleeve; And
Firm banking, described positioning sleeve is fixed on described firm banking.
Preferably, dens supporter, support bar, the axle that seesaws are separately manufactured separately, are then connected into one; Also triplicity can be become to an integral body, manufacture as a whole;
Preferably, locks switch for locking can be zigzag, utilize spring step down, spacing, also can directly utilize the flexible of spring or reverse and realize locking;
Preferably, support arm can be around oscilaltion axle 90-degree rotation, and the motion of 90-degree rotation can utilize the structure at interval, circle side to realize, and also can utilize saw tooth shaped structure to realize, and also can add upper bearing (metal) and realize;
Preferably, the lifting spring that can utilize of lifting part is realized upper and lower smooth motion, also can utilize pneumatic or hydraulic pressure to pass to realize and move up and down;
Preferably, seesawing and the place of moving up and down can be circular shaft, barrel structure, can be also square or other polygonized structures.
This device is designed to it oscilaltion function and dens supporter 90 degree spinfunction functions, greatly improve the operation convenience of mechanism, dens supporter is designed with and moves forward and backward function, can to patient location, regulate fast, move forward and backward locking mechanism, improved the stability of mechanism; System equipment runs into the emergency case such as shut off power in emergency, and patient can oneself take down device, has eliminated potential safety hazard.To sum up, device can reach locates fast to patient, easy to operate, eliminate safe hidden trouble, and the object being fixed well.
