Abstract
A barrel type ratchet wrench with a snap-in structure, including a ratchet acting head installed at a wrench body, a shallow groove formed at a position adjacent to a hollow barrel and having a positioning bolt hole formed at the center of the shallow groove for plugging a direction switching button and a positioning bolt of a ratchet module. A snap plate with an appearance similar to the profile of the shallow groove and having a snap portion, a long hole and a pushing portion is installed under the direction switching button, and a collar having a containing hole corresponsive to a locking component is disposed at the wrench body proximate to the ratchet acting head for containing an elastic member, and the pushing portion of the snap plate has a corresponding end plugged into the containing hole and normally abutted by the elastic member. The snap portion of the snap plate is extended into an edge of the hollow barrel of the ratchet acting head and embedded into a corresponding ring groove of the external socket and the external adapter to prevent unexpected separations.
