Background

The conventional driving tool, such as a wrench, requires a large space for driving the fastener, and after the fastener is pulled to a certain extent, the user needs to pull out the fastener and readjust the angle for inserting, so as to pull the fastener for the next time.

Accordingly, manufacturers have developed reciprocating ratchet heads that allow users to move the wrench back and forth within a small range without having to re-engage the wrench, such as taiwan patent nos. I690394 and M590508.
