Equipped with sliding slot, No. two sliding blocks are further included, the No.1 sliding block and No. two sliding blocks are embedded in sliding slot, the lateral wall of the riser
It is equipped with rectangular recess, one end in the rectangular recess is longitudinally equipped with axostylus axostyle, and the shaft rod upper sleeve has central siphon, the central siphon
Edge is equipped with support arm, and the corresponding position in termination of the support arm and crossbeam lower surface is equipped with threaded hole, in the threaded hole
Equipped with screw, the bottom of the screw is equipped with knop, and the bottom of No. two sliding blocks is equipped with pulley, and the pulley is equipped with
Traction rope, one end of the traction rope are connected with fixed band connection, the other end of the traction rope with hand capstan, the bed
The end surface of body upper bed board is equipped with penetrating groove, and there is movable plate in one end in the groove by hinge connection, further includes
Bracket, the bracket are equipped with jack, and the top of the jack is flexibly connected with one end of movable plate lower surface.
Edge on the madial wall of the riser with bed body is equipped with multiple retainer rings.
The present invention has the following advantages:The present invention voluntarily adjusts the height of fixed band by hand capstan, is conducive to suffer from leg
Practice, the position of fixed band is adjusted by the slip of No. two sliding blocks according to the length of leg, is used easy to different patients,
Crossbeam is merged with riser by shaft, saves space.The upper part of body, which is tilted, by movable plate is easy to different patients couple
The application's operates with.
