Abstract
A bit quick-release device includes a housing having a longitudinal hole in which a first spring and a plunger are respectively received therein. A damping member is located in the longitudinal hole and a radial hole is defined through a wall of the housing so as to receive a locking bead therein. A stop bush is movably mounted to the plunger and a limit ring is mounted to the plunger to prevent the plunger from moving further toward the first spring. A sleeve is movably mounted to the housing and a shoulder portion extends inward from an inner periphery of the sleeve. A second spring is mounted to the housing and biased between the shoulder portion and a stop ring mounted to an outside of the housing.
Claims4
A bit quick-release device comprising:
- a housing having a longitudinal hole defined therein and communicating with an open end at a first end of the housing, a damping member located in the longitudinal hole and in the open end of the housing, a radial hole defined through a wall of the housing and a locking bead movably engaged with the radial hole;
- a first spring received in the longitudinal hole and contacting against a closed second end of the housing, a plunger received in the longitudinal hole and a stop bush movably mounted to the plunger, a limit ring mounted to the plunger and preventing the plunger from moving further toward the first spring, a first end of the plunger fitted with an inner periphery of the longitudinal hole and pushing the locking bead outward, a second end of the plunger contacting the first spring, and
- a sleeve movably mounted to the housing and a shoulder portion extending inward from an inner periphery of the sleeve, a second spring mounted to the housing and biased between the shoulder portion and a stop ring mounted to an outside of the housing.
