1. A one-way drive strap wrench having:
a handle being hollow and having
an axis;an operating knob rotatably mounted on an end of the handle; anda combining unit mounted on the handle and located at a position on the handle opposite to the operating knob; a threaded rod module mounted in the handle and having
a rod body being elongated, rotatably mounted in the handle and having
a fixed segment mounted in the operating knob;a pushing segment opposite to the fixed segment and having a diameter; anda threaded segment connected between the fixed segment and the pushing segment;a nut moveably engaged with the threaded segment of the rob body via threads; a clamping module mounted on the handle and the threaded rod module and having
a clamping block being an asymmetric meniscus, deflectably mounted around the combining unit and having
a convex side being convex and adjacent to the pushing segment;a concave side being concave, opposite to the convex side and having two ends;multiple sawteeth formed on the concave side;a first length defined as a connection between a center of the combining unit and one end of the concave side;a second length defined as a connection between the center of the combining unit and the other end of the concave side, wherein the second length is longer than the first length;an accommodating trough formed in the concave side, accommodating the pushing segment, selectively abutting the pushing segment, and having a trough width wider than the diameter;a strap combined with the nut, circled around the clamping block and having a surrounded area formed between the concave side of the clamping block and the strap, wherein the surrounded area has a central point; a blocking line defined as a connection that passes through the two ends of the concave side; and a crossing angle formed between the axis of the handle and the blocking line and being smaller than 90 degrees. |
