Abstract: A golf club includes a shaft, a grip member, and two constricting and fastening mechanisms to fasten the grip member and the shaft together; the shaft is held in the grip member at a tail portion; the grip member has locating holes, and consists of first and second half shell parts, which are secured together; each constricting and fastening mechanism includes a fastening base secured in the grip member, and fastening member facing the fastening base; the fastening base has through holes, which face the locating holes respectively; the fastening member has threaded holes, which face the through holes respectively; threaded elements are passed through the locating holes and the through holes, and joined in the threaded holes of the fastening member; thus, the shaft will be tightly sandwiched between the fastening base and the fastening member when the threaded elements are turned tight.

Abstract: A golf club includes a shaft, a grip member positioned around a tail portion of the shaft, an expanding component positioned in the tail portion of the shaft, and a fastening component; the grip member has a holding room to receive the tail portion of shaft; the expanding component is made of rubber, and has an axial central hole, and a rugged. outer side; the fastening component has a head part, which has a greater diameter than the central hole of the expanding component; the fastening component has threads thereon; the fastening component is inserted in the axial hole of the expanding component, with the head part being pressed against the grip member so that the rugged outer side of the expanding component is tightly pressed against the inner side of the tail portion of the shaft, and the grip member and the shaft are fastened together.

Abstract: A golf club includes a shaft, and a grip member secured around a tail portion of the shaft; a constricting and fastening component is secured in the grip member to fasten the shaft to the grip member; the constricting and fastening component includes a constricting ring around the shaft, and a driving rod, which can be operated so as to reduce the circumference of the constricting ring in order for the constricting ring to be tight around the shaft, thus preventing the shaft from turning relative to the grip member; the driving rod can be operated so as to expand the constricting ring in order for the ring to loosen the shaft, thus allowing the shaft to be separated from the grip member.

Abstract: A golf club handle includes a body, and an ornamental ring; the body has two adjacent different-color sections, and a color-mixing section at a joint between the two adjacent different-color sections; the handle body is formed with an annular recess on the joint between the two adjacent different-color sections; the ornamental ring is received in the annular recesses so as to cover the color-mixing section of the handle body.

Abstract: A sleeve includes an inner sleeve part securely fitted on a handle end portion of a golf club, and two outer sleeve parts; the inner sleeve part has circular concavities spaced apart on an outer side thereof; the outer sleeve parts are positioned around the inner sleeve part, and each stuck to the inner sleeve part at two ends thereof in a sealing manner such that an air containing sealed room is formed between it and the inner sleeve part, making the sleeve capable of functioning like an air cushion with increased capability to absorb reaction force from hitting a golf ball.

Abstract: A holding device includes a plate member, a hanging piece secured on a rear side of the plate member, and several fastening and supporting mechanisms secured on a front side of the plate member; the holding device is hung on a user's belt by means of inserting the hanging piece in between the belt and the user's waist; each of the fastening and supporting mechanisms includes a fastening member, and a supporting member; the fastening member includes a secured ring, and a fastening loop, which is held in the secured ring, and elastic, expandable and compressible, for passing onto an annular groove of a golf tee; the supporting member includes an external bearing seat, an elastic element located in the external bearing seat, and an internal bearing seat joined to the elastic element and held in the external bearing seat in a movable manner.

Abstract: A golf tee includes an anchor nail and a receptacle. The anchor nail is shaped to taper down to have a sharp lower end so as to easily move into the soil of the ground and plural lengthwise projecting wings spaced apart equidistantly on its outer surface. The receptacle has an annular expanding-out concave member on top for a golf ball to sit thereon stably. As the lengthwise wings of the anchor nail can contact tightly with the soil, the anchor nail will not incline or flow off with the golf ball when hit.

Abstract: A golf club has a handle sleeve around the shaft, which sleeve includes an elastic rubber sleeve part, and an outer covering part; the rubber sleeve part has such an inner diameter as to be tightly secured around the shaft; the rubber sleeve part has a recess portion on an outer side; the covering part includes an inner layer made of the same material as the rubber part, and an outer grip layer; the outer grip layer and the inner layer are sewn together; the outer covering part and the rubber sleeve part are securely stuck together by means of adhesive, which is applied over the inner layer of the outer covering part and the rubber sleeve part, and which has already dissolved the inner layer of the outer covering part and the rubber sleeve part slightly before the outer covering part is positioned onto the rubber sleeve part.

Abstract: An injection-molding tool for a golf club grip includes a base member and a detachable molding member attached thereto. The base member is provided with a screw rod extended therefrom for screw connection. The detachable molding member includes a screw hole for receiving the screw rod of the base member, and a plurality of molding plugs extended therefrom and disposed around the screw hole. Each of the molding plugs has a cross-sectional configuration to thereby form a desired type of a structural elastic buffer of the golf club grip.

Abstract: A grip sheath used for a golf club includes a tapered, elongated hollow body made of an elastomer. The tapered, elongated hollow body has an open end and a closed end opposite to and larger than the open end. The hollow body is formed with a longitudinal central hole extending from the open end towards the closed end and with a plurality of longitudinal blind bores extending from the closed end towards the open end. In addition, the longitudinal blind bores are arranged around the longitudinal central hole. Therefore shock may be significantly absorbed at the grip sheath when a ball is hit by the golf club.
