Claim:
1. A movable spanner structure comprising: a first body including a first retainer extending outwardly from one end thereof, an accommodating groove proximate to the first retainer, and a quadrangle trench defined thereon and communicating with the accommodating groove, wherein the quadrangle trench has a first face and a second face which are formed on two sides of the quadrangle trench, and between the first face and the second face is defined a first distance, the first body also includes a first orifice communicating with the quadrangle trench, and the first body includes a first cavity away from the first retainer, wherein a top surface and a bottom surface of the first cavity are closed, the one end of the first body away from the first retainer is open by ways of the first cavity, and wherein the first cavity has a third face defined on the bottom surface thereof, the first body further includes a first connecting portion passing therethrough and communicating with the first cavity and includes a second cavity communicating with the first cavity and the quadrangle trench; a second body including a second retainer extending outwardly from one end thereof and corresponding to the first retainer of the body, the second body also including a slidable extension disposed thereon and accommodated in the accommodating groove, such that the second body moves straightly in the accommodating groove of the first body, wherein the slidable extension has a first toothed portion arranged thereon, an adjustable bolt fixed in the quadrangle trench of the first body, wherein a length of the adjustable bolt is less than the first distance, and the adjustable bolt includes a second toothed portion formed on an outer side thereof to engage with the first toothed portion of the second body, such that after the adjustable bolt is rotated, it drives the second body to move straightly in the accommodating groove of the first body, and the adjustable bolt also includes a second orifice aligning with the first orifice of the body; a first coupling element fixed in the first orifice of the first body and the second orifice of the adjustable bolt, such that the adjustable bolt is rotatably connected with the quadrangle trench; a locking member accommodated in the second cavity of the first body and including an abutting portion extending outwardly from a first end thereof and mounted in the second cavity, wherein the abutting portion contacts with a first end of the adjustable bolt and has a third orifice passing therethrough and aligning with the first orifice and the second orifice so that the third orifice fits with the first coupling element, and the locking member further includes a first pressing portion; a third body disposed in the first cavity of the first body and including a second connecting portion aligning with the first connecting portion of the first body, the third body also including a second pressing portion abutting against the first pressing portion of the locking member; a second coupling element mounted in the first connecting portion of the first body and the second connecting portion of the third body, such that the third body is rotatably coupled with the first body.
