Abstract

A socket apparatus includes a socket, at least one detent and an elastic element. The socket includes a bit-receiving recess in an end, a mandrel-receiving recess in an opposite end, at least one vent in communication with the mandrel-receiving recess and at least one aperture in communication with the mandrel-receiving recess. The detent is inserted in the aperture so that the detent includes a portion disposed in the mandrel-receiving recess. The elastic element is used to bias and keep the detent in the aperture.

Claims

a socket comprising a bit-receiving recess in an end, a mandrel-receiving recess in an opposite end, at least one vent in communication with the mandrel-receiving recess and at least one aperture in communication with the mandrel-receiving recess;

at least one detent disposed in the aperture so that the detent comprises a portion disposed in the mandrel-receiving recess; and

an elastic element for biasing and keeping the detent in the aperture.

2. The socket apparatus according to claim 1, wherein the length of the mandrel-receiving recess is at least one third of that of the socket.

3. The socket apparatus according to claim 1 comprising three detents.

4. The socket apparatus according to claim 1, wherein the elastic element is an elastic ring.

5. The socket apparatus according to claim 1, wherein the elastic element is a C-clip.

6. The socket apparatus according to claim 1, wherein the mandrel-receiving recess comprising a square section and a circular section, the vent is in communication with the square section of the mandrel-receiving recess, and the aperture is in communication with the circular section of the mandrel-receiving recess.

7. The socket apparatus according to claim 1, wherein the socket comprises a groove in communication with the aperture, and the elastic element is disposed in the groove.
