Description

Socket spanner with adjustable bore

Technical Field

The utility model belongs to the technical field of hardware and tools, a spanner is related to, in particular to socket spanner with adjustable bore.

Background

The spanner is a common manual tool for screwing a screw by utilizing a lever principle in the field of machinery, the socket spanner is mainly used for screwing the screw which is turned in the counter bore, and because the periphery of the screw in the counter bore does not have enough space, the socket spanner needs to be stretched into the counter bore to clamp the end part of the socket and the head part of the screw, and then the handle is rotated to screw out the screw. Among the prior art, box spanner all is the sleeve of a handle cooperation a plurality of sizes, changes suitable sleeve according to actual conditions on the handle when using, and the convenience is relatively poor to the sleeve of taking off loses easily.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a use more convenient and portable's socket spanner with adjustable bore.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a socket spanner with adjustable aperture, includes sleeve pipe, screw rod, clamp splice and lock nut, its characterized in that, the spline structure has been seted up in the upper end outside of screw rod and wears to locate in the sleeve pipe through spline structure and the fit of intraductal keyway of cover, the lower extreme of screw rod has the stair structure and rises with sleeve pipe port hole through stair structure and tightly reciprocal anchorage, the screw rod on lie in the stair structure below and seted up the external screw thread, lock nut set up in the screw rod tip through screw-thread fit, axial seted up the draw-in groove on the terminal surface of screw rod and form the incision at draw-in groove bottom surface central axial extension, the clamp splice symmetry set up in the draw-in groove and prevent to drop through lock nut, two the opposite face of clamp splice forms for inside sunken triangular structure keeps silent, the lower extreme outside of clamp splice be with lock nut inner wall matched with inclined plane structure.

In this box spanner, the screw rod is worn to locate the intraduct and is prevented through the spline structure that take place rotation each other between screw rod and the sleeve pipe, simultaneously through the stair structure on the screw rod make the screw rod and the sleeve pipe between rise tightly fixed, the clamp splice symmetry is placed and is made it can be in the draw-in groove translation each other, and realize the regulation of keeping silent the size through the relative position between two clamp splices, its regulative mode does, for screw-thread fit between lock nut and the screw rod, it is movable from top to bottom on the screw rod to make it move about through lock nut's rotation, because lock nut and clamp splice's contact surface is the inclined plane structure, consequently two clamp splices move in opposite directions when lock nut goes up the accent, keep silent and diminish, vice versa keep silent the grow, thereby realize this box spanner and the screw cooperation of different models.

In the caliber-adjustable socket wrench, a U-shaped elastic sheet is connected between the two clamping blocks, two bottom feet of the U-shaped elastic sheet penetrate into the clamping blocks for fixation, and the top of the U-shaped elastic sheet is located in the notch.

In the caliber-adjustable socket wrench, the upper end of the sleeve radially penetrates through the long-strip-shaped handle, and the two ends of the handle are both provided with a circle of groove.

In the caliber-adjustable socket wrench, the through hole communicated with the cavity where the handle is located is formed in the inner bottom surface of the sleeve, the steel ball is arranged below the through hole, the diameter of the steel ball is larger than that of the through hole, and the spring is arranged between the steel ball and the top surface of the screw rod.

In the caliber-adjustable socket wrench, the upper end surface of the sleeve and the outer wall of the locking nut are both provided with a net-shaped anti-slip structure.

Compared with the prior art, the adjustable-caliber socket wrench has the advantages that the jaw size can be adjusted by vertically moving the locking nut at the end part of the screw rod, the adjustment is more convenient, the handle which can move left and right is penetrated on the sleeve, and the adjustable-caliber socket wrench is more convenient and labor-saving in use.
