Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step are within the scope of the present invention.
Example (b): an impact sleeve extension rod with a rotating sleeve.
Referring to fig. 1 to 4, an impact socket extension pole with a rotary sleeve includes: extension rod body 1, extension rod body 1 includes the body of rod 11, the work piece butt joint hole with the work piece butt joint is seted up to the front end of the body of rod 11, set up on the lateral wall of the body of rod front end with the communicating locking screw hole 12 of work piece butt joint hole, toper transmission butt joint 13 integrated into one piece sets up the rear end at the body of rod 11, transmission butt joint hole has been seted up to transmission butt joint 13 rear end.
