Description of the embodiments

The present utility model will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown, for the purpose of illustrating the utility model, but the scope of the utility model is not limited to the specific embodiments shown.

As shown in fig. 1-4, the multifunctional quick wrench of this embodiment includes a wrench head 2 and a handle 1 connected with the wrench head 2, the wrench head 2 is integrally provided with a hook with an opening at one side, a mounting groove is provided at one side of the wrench head 2 close to the handle 1, a friction block 3 is rotatably mounted in the mounting groove, the friction block 3 is elastically matched with the mounting groove through a torsion spring, the tail end of the friction block 3 is an inclined plane inclined to one side of the wrench head 2, a plurality of tooth grooves are provided on the inclined plane, the inner wall of the wrench head 2 comprises a circular arc section 201 opposite to the opening and a plane section 202 positioned at the end, a plurality of movable ratchet teeth 4 are uniformly arranged at intervals on the circular arc section 201, the movable ratchet teeth 4 are movably embedded in the wrench head 2, a spring 5 is arranged between the inner end of the movable ratchet teeth 4 and the wrench head 2, the outer end of the movable ratchet teeth 4 is an inclined plane inclined to one side, and when the spring 5 is in a natural state, the outer end inclined plane of the movable ratchet teeth 4 does not exceed the circular arc section 2.

In this embodiment, the wrench head 2 includes a main body frame 203 and cover plates 204 located on two sides of the main body frame 203, screw holes are correspondingly formed in the cover plates 204 and the main body frame 203, and the cover plates 204 are fastened and connected with the main body frame 203 through bolts. The main body framework 203 is provided with a groove, the spring 5 is arranged at the bottom of the groove, the movable ratchet 4 is inserted into the groove, two ends of the movable ratchet 4 are respectively provided with a clamping pin, a waist-shaped groove 205 is arranged on the cover plate 204 at a position corresponding to the clamping pin of the movable ratchet 4, and the clamping pin is arranged in the waist-shaped groove 205.

Fig. 5 is a schematic view showing the application of the multifunctional spanner of the present embodiment to an aviation socket nut. When the aviation socket nut is used, the friction block 3 is broken by hand, the aviation socket nut is clamped into the spanner head 2, the aviation socket nut is tightly attached to the inner wall arc section 201 of the spanner head 2, after the friction block 3 is loosened, the friction block 3 is tightly attached to the aviation socket nut under the action of the torsion spring, the spanner head 2 is rotated forward through the handle 1, at the moment, the movable ratchet 4 props against the convex teeth on the aviation socket nut relative to one side of the inclined plane, so that the aviation socket nut can be rotated, after a certain angle is rotated, the spanner head 2 is rotated reversely, at the moment, because one side of the movable ratchet 4, which contacts with the convex teeth of the aviation socket nut, is the inclined plane, the movable ratchet 4 can be pressed into the groove of the main body framework 203 under the action of the convex teeth of the aviation socket nut, after the movable ratchet 4 is moved over the convex teeth of the aviation socket nut, the movable ratchet 4 is reset under the action of the spring 5, and then the spanner head 2 is rotated forward again, and the aviation socket nut can be rotated continuously.
