Claims

[Scope of Claim for Utility Model Registration] A ratchet gear rotatably mounted on the tip of a handle, and a ratchet gear pivotally mounted on the handle to restrict rotation of the ratchet gear only in the forward direction. A first ratchet pawl that can engage with the ratchet gear, and a second ratchet pawl that is pivotally connected to the handle and can engage the ratchet gear to restrict rotation of the ratchet gear only in the opposite direction; A first ratchet pawl attached to the handle and elastically engaged with the first ratchet pawl to maintain engagement between the first ratchet pawl and the ratchet gear.
a second elastic member attached to the handle and elastically engaged with the second ratchet pawl to maintain engagement between the second ratchet pawl and the ratchet gear; selectively disengaging the first and second ratchet pawls of the ratchet. an operating lever pivotally connected to the handle and having a cam that can be disengaged from the ratchet gear, the operating lever being in a first operating position where the cam displaces the first ratchet pawl; , a second operating position in which the cam displaces the second ratchet pawl, and a neutral operating position in which the cam does not displace either the first or second ratchet pawl. A ratchet handle characterized by being equipped with a locking mechanism that can be held in place.
