摘要
<p>The structure has a support part formed on an end of a handle (10). A folded pipe part (15) is formed on another end of the handle and rotationally coupled with a casing (11). A cladding part (111) is formed on an end of the casing. A ratchet part (112) is formed on another end of the casing and engaged with a blocking element (17) to restore a bidirectional position in an elastic manner to constitute a bidirectional ratchet pipe wrench. The folded pipe part has a bidirectional switch (122) arranged on a prolonged position. A blocking part (151) includes a hole and a rotary part (12).</p>
