Claw massage apparatus

A claw massage apparatus comprising:

• a drive mechanism, comprising an impeller and an upper cover;
• the impeller comprises a wheel body and blades disposed on the wheel body, and the wheel body is connected to a transmission mechanism in a transmission way;
• the upper cover is disposed around the impeller, and is provided with water inlet holes in communication with the impeller;
• a water flow is able to enter the impeller through the water inlet holes, and flush the blades to rotate the impeller, so as to drive rotation of the transmission mechanism;
• the transmission mechanism is configured to be driven by the drive mechanism to rotate, and the transmission mechanism being provided with a moving rail, the transmission mechanism comprising a rail plate that is driven by the drive mechanism to rotate, and the rail plate defines a motion track;
• a base to which the transmission mechanism is rotatably connected;
• a plurality of massage mechanisms, which are supported by the base, each of the massage mechanisms comprising a connecting part connected to the moving rail in the transmission way and a massage claw positioned outside the base;
• wherein the drive mechanism is configured to drive rotation of the moving rail, wherein an outer circumference of the rail plate forms the moving rail;
• the connecting part of the massage mechanism comprises a connecting body and a first connecting post, and the first connecting post is protruded along an axis at a top of the connecting body;
• the massage claw comprises a first connecting sleeve and a claw body;
• the first connecting sleeve is fixed to an upper end of the claw body and is sleeved with the connecting body, and the claw body is positioned outside the base;
• an outer circumference of the first connecting post is closely attached to the outer circumference of the rail plate, during the rotation of the rail plate, the first connecting post is pushed by the outer circumference of the rail plate to move to drive the respective connecting parts to synchronously swing, so that the respective massage claws are close to or away from each other, such that the respective massage claws move between a first extreme position and a second extreme position;
• in the first extreme position, the respective massage claws are close to each other;
• in the second extreme position, the respective massage claws are distanced from each other;
• and
• tension springs, which are disposed on the inner circumference of the base and abut against the first connecting posts, respectively;
• as the moving rail rotates, the first connecting post gradually approaches to the first position, and gradually compresses the tension springs;
• when the respective first connecting posts are in the first positions, the tension springs are further compressed, to accumulate an elastic restoring force toward a center of the moving rail for the respective first connecting post.
