Detailed Description

The technical solutions of the present embodiment will be clearly and completely described below with reference to the accompanying drawings, and the described embodiments are only some embodiments, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any creative effort based on the embodiments of the present embodiment are all within the protection scope of the present solution.

Example 1

As shown in fig. 1 to 3, the present embodiment is designed to include a wrench head 1, and a wrench opening 2 is provided in the wrench head 1.

The wrench opening 2 is composed of a parallel groove portion 21 and a polygonal groove 22. The parallel groove portions 21 have a groove structure in which inner side walls are parallel to each other, and the width of the parallel groove portions 21 should be slightly larger than the width between opposite sides of the nut or screw, so that the nut or screw can be quickly matched and screwed by using the parallel groove portions 21. The polygonal groove 22 is a groove structure with inner side walls profiled on continuous sides of a regular polygon, and the polygonal groove 22 can be engaged with a nut or a screw, so that the polygonal groove 22 is used for applying larger torsion force to the nut or the screw, and the nut or the screw is screwed or unscrewed.

The parallel groove portion 21 intersects with the polygonal groove 22, and the width of the notch of the polygonal groove 22 is larger than that of the parallel groove portion 21, so that an inner concave portion 23 is formed on the inner side wall of the wrench opening 2, and the inner concave portion 23 is located at the intersection of the parallel groove portion 21 and the polygonal groove 22.

When the spanner head 1 turns a screw with a hexagonal nut or a hexagonal nut:

when the screw or the nut is required to be screwed or unscrewed, the screw or the nut is clamped into the polygonal groove 22, the polygonal groove 22 can be meshed with the screw or the nut, and the hexagonal nut or the screw is supported in multiple points, so that the screw or the nut is not easy to damage in the screwing or unscrewing process, and the nut or the screw is protected.

Before or after the screw or the nut is screwed down, the direction of the wrench head 1 needs to be converted when the wrench head 1 is twisted by a certain angle, so that the screw or the nut can be clamped into the parallel groove part 21, thereby realizing rapid alignment and matching and improving the screwing efficiency of the nut or the screw.

When the screw is a hexagonal nut screw or the nut is a hexagonal nut, the polygonal groove 22 is contoured to three consecutive sides of a regular hexagon.

The wrench head 1 is provided with a rear handle 3 at one side facing away from the wrench opening 2, and the rear handle 3 is connected with the wrench head 1 into a whole. A rotating tongue 4 is arranged at one end of the rear handle 3 far away from the spanner head 1, and the rotating tongue 4 is connected with a rotating handle 5 through a rotating shaft 8; the rotation handle 5 is rotatable in the thickness direction of the wrench head 1. The end of the rotating handle 5 far away from the spanner head 1 is provided with a handle connecting tongue 6, the handle connecting tongue 6 is in a flat bar shape, and the width direction of the handle connecting tongue 6 is the same as the width direction of the spanner head 1. The thickness of the handle connecting tongue 6 is the same as that of the rear handle 3; the rotation angle range of the rotation handle is +/-90 degrees. Through the design of the rotating handle 5, the spanner head 1 can rotate within the range of 0-90 degrees relative to the rotating handle 5, so that the spanner is convenient to use in corresponding limited environments.

Outer protruding portions 7 are arranged on two opposite end faces of the wrench head 1 in the thickness direction, so that the strength of the wrench head 1 is enhanced, and deformation of the wrench head 1 when being stressed is reduced.

Example 2

As shown in fig. 1, 4 and 5, the present embodiment designs a wrench structure including a wrench head 1, and a wrench opening 2 is provided in the wrench head 1.

When the spanner head 1 turns a screw with a hexagonal nut or a hexagonal nut:

The wrench head 1 is provided with a rear handle 3 at one side facing away from the wrench opening 2, and the rear handle 3 is connected with the wrench head 1 into a whole. The end of the rotating handle 5 far away from the spanner head 1 is provided with a handle connecting tongue 6, the handle connecting tongue 6 is in a flat bar shape, and the width direction of the handle connecting tongue 6 is the same as the width direction of the spanner head 1.

Outer protruding portions 7 are provided on opposite end surfaces of the wrench head 1 in the thickness direction. Thereby strengthening the strength of the wrench head 1 and reducing the deformation of the wrench head 1 when being stressed.
