a first elastic limit unit inserted in the insertion hole of the pivot rod, the first elastic limit unit being able to extend in the limit groove of the handle so that the handle is able to axially move on the pivot rod through the limit groove; and
a second elastic limit unit inserted in the recess of the driving head, the second elastic limit unit being able to engage with the limit recess.
2. The multi-function socket wrench as claimed in claim 1, wherein the second elastic limit unit includes a spring and a steel ball which are placed in the recess in sequence, and the steel ball is exposed out of the recess to be received in the limit recess of the handle.
3. The multi-function socket wrench as claimed in claim 1, wherein the first elastic limit unit includes a steel ball, a spring and a stop member which are placed in the insertion hole in sequence, the steel ball is exposed out of the insertion hole to extend in the limit groove of the handle, and the stop member is screwed in the insertion hole to block the spring.
4. The multi-function socket wrench as claimed in claim 3, wherein the stop member is a screw, and the pivot rod has inner threads on an inner wall of a rear section of the insertion hole.
5. The multi-function socket wrench as claimed in claim 1, wherein the driving head is a ratchet-type tool head.
The claims below are in addition to those above.
