Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a thin type S type spanner of high tenacity, including handle 3, handle 3 is including horizontal end and arc end, 3 arc both ends of handle all are connected with locating piece 7 through 2 rotations of axis of rotation, one side that handle 3 was kept away from to locating piece 7 is provided with bolt nut 1, 2 inner chambers of axis of rotation are provided with locating pin 8, design through 2 cooperation locating pin 8 of axis of rotation, make S type spanner can carry out bolt nut 1 and handle 3' S angle variation according to the difference of the distance between the fastener, thereby make bolt nut 1 better combination fastener, thereby the application scope of S type spanner has been improved.

Specifically, as shown in fig. 1 and 2, one side of the bolt and nut 1 close to the positioning block 7 is fixedly provided with a combination block 6, the combination block 6 is clamped with the positioning block 7, the combination block 6 and the positioning block 7 are fixedly connected through a screw rod 5, the screw rod 5 is combined with or separated from the positioning block 7, the bolt and nut 1 and the combination block 6 are disassembled or installed, so that fasteners of different sizes are disassembled or the bolt and nut 1 is worn too much and is scrapped, only the bolt and nut 1 needs to be replaced, and the use effect of the S-shaped wrench is improved while the device cost is ensured.
