Patent ID: 7744548

Claim:
A massaging device, comprising: a propeller shaft; at least one first swinging member mounted on the propeller shaft; at least one second swinging member mounted on the propeller shaft by a male deflection block, a female deflection block and an adjusting rod; wherein the adjusting rod has an inner wall formed with a fixing hole secured on the propeller shaft to rotate with the propeller shaft so that the adjusting rod is rotatable by the propeller shaft; the adjusting rod has an outer wall provided with a protruding push block; the male deflection block has an inside formed with a mounting bore mounted on the outer wall of the adjusting rod and has an end wall formed with an adjusting groove connected to the mounting bore to receive and guide movement of the push block of the adjusting rod and to guide rotation of the adjusting rod relative to the male deflection block; the second swinging member has an end portion formed with a mounting hole; the end wall of the male deflection block is provided with a protruding insert extended through and protruded from the mounting hole of the second swinging member; the female deflection block has an end wall formed with a slot to allow insertion of the insert of the male deflection block so that the male deflection block and the female deflection block are joined together and are rotatable simultaneously; the insert of the male deflection block has a substantially square profile; the slot of the female deflection block has a substantially square profile matching that of the insert of the male deflection block so that the slot of the female deflection block is secured on the insert of the male deflection block, and the female deflection block is secured on the insert of the male deflection block to rotate in concert with the male deflection block; the propeller shaft has a substantially hexagonal cross-sectional profile; the fixing hole of the adjusting rod has a substantially hexagonal cross-sectional profile matching that of the propeller shaft so that the fixing hole of the adjusting rod is secured on the propeller shaft.
