Abstract
A fabrication method of a holding sleeve is provided. The holding sleeve is adapted to dispose around a body portion of a main body and can rotate relative to the body portion. A blocking member is disposed in at least one through hole of a first sleeve. A second sleeve is movable relative to and disposed around the first sleeve. The blocking member is controllably pressed by the second sleeve to be partially received in an annular groove of the body portion. An elastic member is disposed around and between the first sleeve the first and second sleeves. Before the second sleeve is mounted to the first sleeve, a part of the elastic member corresponds to the blocking member in a radial direction of the first sleeve and can limit the blocking member to locate in the through hole.
Claims13
A fabrication method of a holding sleeve, including the following steps:
- providing a first sleeve which is substantially tubular and formed with at least one through hole and a stepped shoulder portion, wherein the at least one through hole is disposed between a distal end of the first sleeve and the stepped shoulder portion, the distal end is nearer the at least one through hole than the stepped shoulder portion;
- disposing at least one blocking member in the at least one through hole;
- disposing an elastic member around the first sleeve, wherein the elastic member is a coil spring, one end of the elastic member is abutted against the stepped shoulder portion of the first sleeve, without being depressed, an other end of the elastic member statically interferentially corresponds to the blocking member in a radial direction of the first sleeve so as to prevent disengagement of the at least one blocking member from the at least one through hole, and wherein as viewed in the radial direction of the first sleeve, without being depressed, two diametric portions of at least one coil of the coil spring statically at least partially overlap the at least one blocking member;
- and
- disposing a second sleeve around the first sleeve, wherein the elastic member is compressed between and abutted against the stepped shoulder portion and the second sleeve, the second sleeve is controllably movable relative to the first sleeve, and the at least one blocking member is abutted by the second sleeve so as to controllably partially go into the interior of the first sleeve.
