Japanese Patent JP7027428

B2

The present invention discloses a ratchet clamp comprising a first clamping arm and a second clamping arm which are pivotally connected with each other via a connecting shaft so as to be opened and closed relative to each other, a ratchet assembly, a swing assembly and a control assembly provided between the first clamping arm and the second clamping arm; the ratchet toothed assembly has a plurality of first ratchet teeth and a plurality of second ratchet teeth which are juxtaposed and are misaligned with each other; the swing assembly and the ratchet toothed assembly are moved away from or towards each other with the connecting shaft as the axial center of rotation; a latch member of the control assembly has at least a first pawl and at least a second pawl, a wrench member of the control assembly is used for toggling the latch member to be moved, the first pawls and the second pawls are respectively engaged with the corresponding first ratchet teeth and second ratchet teeth when the latch member is moved to an engaged position, and the first pawls and the second pawls are respectively moved away from the corresponding first ratchet teeth and the second ratchet teeth when the latch member is moved to a released position. With the misaligned ratchet tooth design, the tooth profile may not be reduced, thereby increasing the structural strength, so that the overall clamping force is greatly enhanced.
