Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts, unless otherwise specified.

The special socket wrench shown in fig. 1 comprises a shaft sleeve 1 and a mounting disc 3, wherein a square hole 2 which is connected with a torque wrench and is arranged along the axial direction of the torque wrench is arranged at the left end of the shaft sleeve 1, and the right end of the shaft sleeve is connected with the mounting disc 3 through a pin shaft 4. The right end face of the shaft sleeve 1 is provided with a first positioning hole in interference fit with the pin shaft 4, the left side face of the mounting disc 3 is provided with a second positioning hole corresponding to the first positioning hole in position, and the second positioning hole is in interference fit with the pin shaft 4. The edge all around on 3 right sides of mounting disc is equipped with 4 tooth 31 of the breach of blocking circular nut. The shaft sleeve 1 and the mounting disc 3 are coaxial in center. In order to improve the functionality of the tool, a through hole 11 is provided at the left end of the sleeve 1, perpendicular to the axis thereof, and the sleeve 1 can be rotated by a rod-shaped object passing through the through hole 11. In order to reduce the overall weight of the socket wrench, the weight-removing holes 6 are dug in the shaft sleeve 1 and the mounting plate 3 under the condition that the normal use of the wrench is not influenced.

In order to further improve the rotation of the socket wrench, the left end of the shaft sleeve 1 is designed to be a structure of a secondary stepped column 5, and the side surface of each stepped column is cut into flat positions, so that two open-ended wrenches with different numbers can clamp and rotate the tool.

The utility model discloses a use method: according to the assembly depth of the round nut, the distance between the right end face of the shaft sleeve 1 and the mounting disc 3 is adjusted through the pin shaft 4, then the notch of the round nut is clamped by the teeth 31 of the mounting disc 3, the right side of the mounting disc 3 is abutted to the surface of the round nut, the torque wrench is installed in the square hole 2 of the shaft sleeve 1, and the round nut can be detached or tightened by rotating the torque wrench.

Those skilled in the art will recognize that numerous variations are possible in light of the above description, and therefore the examples and drawings are merely intended to describe one or more specific embodiments.

While there has been described and illustrated what are considered to be example embodiments of the present invention, it will be understood by those skilled in the art that various changes and substitutions can be made therein without departing from the spirit of the invention. In addition, many modifications may be made to adapt a particular situation to the teachings of the present invention without departing from the central concept described herein.
