Description
Technical field:
The utility model relates to a kind of locking mechanism of pneumatic screw driver tool heads.
Background technology:
When pneumatic screw driver uses, need often to change the tool heads that different manufacturers is produced, because its locating slot position does not have unified standard, after tool heads is in place, soaring in its bottom, in the use under the tool heads effect of active force outside, forces the locking steel ball and lock sliding sleeve and push mutually, cause the locking sliding sleeve and steel ball is stuck or damage, influence is use normally.
The utility model content:
The purpose of this utility model is to solve the problems referred to above that the locking mechanism of existing pneumatic screw driver tool heads exists, and a kind of locking mechanism of novel pneumatic screw driver tool heads is provided.It has compact conformation, and long service life is changed advantages such as tool heads convenience.
For achieving the above object, the solution that the utility model is taked is: a kind of locking mechanism of pneumatic screw driver tool heads, it comprises the pneumatic screw driver output shaft, locking sliding sleeve and locking steel ball, radially have a step through-hole on the pneumatic screw driver output shaft, the locking steel ball is installed in this step through-hole, the pneumatic screw driver output shaft end has the tool heads installing hole, the tool heads that has lock slots is installed in this tool heads installing hole, the locking sliding sleeve is installed on the pneumatic screw driver output shaft, in the locking sliding sleeve elastic ring is housed, in the locking sliding sleeve, the pneumatic screw driver output shaft also is with spring outward.
Characteristics of the present utility model are: under the effect of spring, after the locking sliding sleeve moves into place, elastic ring is pushed mutually, to reach the purpose of locking tool head reliably working with the locking steel ball; Even the locking steel ball is outwards pushed, owing under the elastic yield effect of elastic ring, guarantee locking steel ball, locking sliding sleeve and tool heads reliably working.It has compact conformation, and long service life is changed advantages such as tool heads convenience.
Description of drawings:
Fig. 1 is the structural representation of present embodiment.
Among the figure: 1, tool heads, 2, back-up ring one, 3, locking steel ball, 4, the locking sliding sleeve, 5, elastic ring, 6, spring, 7, back-up ring two, 8, pneumatic screw driver output shaft.
The specific embodiment:
