the outside of fixed block 5 and the both sides that are located appearance chamber 6 have seted up movable groove 21, the degree of depth of movable groove 21 is the same with the distance that the fixed block 5 removed when contracting, the mouth 22 of blowing has been seted up to the both sides of movable groove 21, the distance of the mouth 22 opening of blowing to movable groove 21 tank bottoms portion is greater than the thickness of exhaust piston 23 stopper plate, the swing joint of movable groove 21 has exhaust piston 23, pi shape through-hole has been seted up to exhaust piston 23 stopper plate inside, exhaust piston 23 keeps away from the right side and the 3 sliding connection of swivel becket of movable groove 21.

The working principle and the process of the invention are as follows:

when the arm pad is used, the frame pad 1 is wrapped at an arm wound wrapping position, the frame pad 1 is inflated through the inflator, so that the frame pad 1 gradually swells, and the arm is tightly wrapped through the eleven fixing blocks 5.

A user lies and turns over the arms and turns over along with the body, sits and stands the arm and places the posture and change or walk the arm swing, make the outside of frame pad 1 trigger block 2 squeezed like this, as fig. 3-4, trigger block 2 squeezes into the concrete chute 4, drive a corresponding rotating ring 3 anticlockwise rotation, the rotating ring 3 pulls the slide bar 10 to move through the pull rod 12, tooth and half-gear meshing when the slide bar 10 moves, as fig. 17 and 19, lock the movable tooth 9, the slide bar 10 drives the rack 7 to move through sliding sleeve 8 and movable tooth 9 like this, pull the fixed block 5 into frame pad 1, unclamp the arm, make this part muscle blood unblocked.

When the rotating ring 3 rotates to drive the fixing block 5 to contract and the fixing block 5 contracts, the exhaust piston 23 is extruded into the movable groove 21, and when the pi-shaped through hole is overlapped with the air blowing port 22, high-pressure air in the frame cushion 1 is exhausted through the pi-shaped through hole and the air blowing port 22 and blows on the extruded part of the fixing block 5.

When 5 shrink of fixed block loosened the arm like this, the sweat stain of exhaust air can be with the fixed department weathers, prevents the sweat stain fermentation, produces a large amount of bacteriums, influences the wound and resumes.

The rotating ring 3 rotates anticlockwise, the rotating ring 3 drives the air suction piston 17 to move, the space on the left side of the air suction piston 17 is reduced to compress air, the rubber tube 20 at the opening of the extrusion opening 18 is flattened by air pressure, the extrusion opening 18 is closed, the space on the right side of the air suction piston 17 is enlarged, the air pressure is reduced, the rubber tube 20 at the opening of the suction opening 19 is expanded, air is sucked into the cushion 1, lost air is supplemented, and the cushion 1 is prevented from being reduced and influenced to be fixed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
