The invention relates to a pneumatic massage bath-assistance chair. The pneumatic massage bath-assistance chair comprises a chair body, wherein a back rubbing unit for rubbing the back, a knocking unit for knocking and massaging the back and a shower unit for showering are arranged on the back of the chair. The chair is reasonable in structure and convenient to use, whole-course automation and convenience of back rubbing when old people and motion-inconvenient people take shower at home can be realized by utilizing a pneumatic technology, automatic operation of the knocking unit and back rubbing unit can be guaranteed by utilizing a rotary air valve, and a pneumatic slide valve, a transmission mechanism and a pneumatic motor, so that the electric shock caused by adopting an existing electric transmission mode can be avoided. The chair has high safety performance, a perforated leg supporting plate is arranged inside a foot soaking basin, bubble massage is formed for foot soles by utilizing exhausted pressure air, foot sole acupoints can be stimulated by utilizing bubble shock, blood circulation is promoted, the health-care effect is good, and the requirement for existing aging society can be met.

The invention discloses a fastening stitching anti-separation socket, and the socket comprises a support body and conductive mechanisms disposed on the support body. The number of conductive mechanisms is two, and the two conductive mechanisms are symmetrically disposed at the bottom of a rotating core. Each conductive mechanism comprises an electrode elastic metal piece and an electrode guide rail. An outgoing line end of a toggle switch is connected with the electrode elastic metal pieces, and the electrode guide rails are respectively shaped like an arc, and are fixed at the bottom of the rotating core. The electrode guide rails are attached to the electrode elastic metal pieces, and are connected with metal press plates at the corresponding sides through wires. The upper surfaces of the electrode elastic metal pieces are provided with bulged conductive projections, and the upper end faces of the conductive projections are closely attached to the lower end faces of the electrode guide rails. The adding of the conductive projections enables the frictional force between the electrode guide rail and the electrode elastic metal pieces to be reduced, and guarantees the close contact.
