Claims

[Claims for Utility Model Registration] 1. A rotating member 10 having a mouth 11 and having teeth 12 with an acute convex cross section formed on the outer periphery, and a rotary member 10 rotatably supported and a handle 3 fixed to the outside. At the same time, a case 1 having an open portion 2 formed therein; and a case 1 disposed within the case 1 and operated so as to be able to engage with the tooth portion 12 when rotating in one direction and not to engage when rotating in the opposite direction. A spanner comprising: a locking means; and an operation means connected to the locking means to operate the locking means. 2. The spanner according to claim 1, wherein the case has a guide surface 4 that guides the rotating member 10 so that it always rotates around the same center. 3. The locking means includes a cam 20 which is rotatably supported by the case 1, and which is swingable by the cam 20 and whose tip can engage with the toothed portion 12. A pair of pawls 21 and 22 are pivotally supported by the case 1 in contact with the cam 20 so that the other pawl 22 is prevented from engaging when the cam 20 is engaged with the cam 20. 2. A spanner according to claim 1 or 2, characterized in that the wrench comprises springs 23 and 24 arranged in the case 1 so as to be biased into contact with the springs 23 and 24. 4 The operating means includes levers 31 and 32 connected to the cam 20 of the locking means, and these levers 31 and 32.
A spanner according to claim 1, 2, or 3 of the utility model registration, characterized in that the wrench constitutes a link mechanism consisting of an arm 30 rotatably attached to both ends of the wrench.
