Abstract
This present invention discloses a socket for wrenches, which comprises a main body having a proximal section, a distal section, and a central axis extending from proximal section to distal section. The main body has recess at inside on the proximal section with punctures on the recessed periphery and each puncture has a moving part mounted therethrough. A sleeve is in slide-fitting communication with the main body, which has an inner wall provided a plurality of push fronts thereon, each push front surface rises gradually by a plurality of continuous steps from one end to the other. When the sleeve is rotated of axially moved with respect to the main body, the gradual rising steps of the push fronts are pushing the moving parts toward the central axis to match with varieties of scales of work pieces.

A socket for wrenches comprises:
- a main body having a proximal section, a distal section, and a central axis extending from the proximal section to the distal section, the distal section having a square receiving hole, the proximal section having a recess connecting with the square receiving hole and three radially extending punctures connecting with the recess, the outline of the recess being in the shape of hexagon in the view of a cross-section which is vertical with respect to the central axis, each puncture having a moving part radially movably mounted therethrough, the moving part having a primary end formed a plane surface and a secondary end formed a first arc surface;
- a ball groove is implemented on the periphery of the main body with a spring and a sphere mounted therein;
- and
- a sleeve having an inner wall and being in slide-fitting communication with the outside of the main body, and having a second central axis parallel with the central axis of the main body, the inner wall of the sleeve provided three push fronts thereon each corresponding to one moving part, wherein the push front on the inner wall of the sleeve shaped as continuous steps, the steps of each push front rising gradually from one end to the other, and the inner wall of the sleeve provided a plurality cavities thereon, the cavities implemented to have the sphere to be positioned thereinto, and the distance of the center of two adjacent cavities is equal to the distance of the center of two adjacent steps of each push front;
- so that the steps of the push fronts can push the moving parts toward the central axis by steps when the sleeve is moved with respect to the main body.
