发明名称 Ratchet wrench having a rigid locking structure
摘要 A ratchet wrench having a rigid locking structure includes a wrench body, a ratchet wheel, a pawl member, and a restoring member. Thus, the support blocks of the pawl member are urged on the wall of the receiving chamber of the wrench body, thereby forming a double-support or multi-support structure between the pawl member and the wall of the receiving chamber of the wrench body, so that the locking teeth of the pawl member are engaged with the ratchet teeth of the ratchet wheel actually, closely, rigidly and stably, thereby increasing the efficient torque of the ratchet wrench, and thereby facilitating the user operating the ratchet wrench.
