Abstract

The utility model discloses a multifunctional torque spanner which comprises a ratchet (7), a telescopic handle and a groove (3). The telescopic handle comprises an inner handle (2) and an outer handle (6); a bayonet (4) is arranged at one end of the outer handle (6); a clamping section (3) is arranged at one end in the outer handle (6) where the inner handle (2) can be inserted into the outer handle (6); the groove (3) matched with the shape of a tightening position of a fastening piece is formed at the bottom of the outer handle (6); and the ratchet (7) rotating along the inner handle (2) by taking a pin (1) as an axis is connected with the upper part of the inner handle (2) through the pin (1), so that the length of the handle can be adjusted freely. The multifunctional torque spanner is convenient to use and carry; the tightening position of the fastening piece can fall into the groove; multiple surfaces are simultaneously and uniformly stressed; and the multifunctional torque spanner is convenient and effective to use, so that functions of the multifunctional torque spanner is not single any longer.

Description

A kind of multi-functional torque spanner

Technical field

The utility model relates to a kind of spanner, is specifically related to a kind of multi-functional torque spanner.

Background technology

Spanner has been widely used in building field at present, it utilizes lever principle to twist bolt, screw, nut and other screw threads and tightly holds the opening of bolt or nut or the hand tools of trepanning firmware, spanner usually is shaped with clamp holder section and applies the external force shank and apply external force in the one or both ends of shank, just can twist bolt or nut and hold opening or the trepanning of bolt or nut, apply external force along the screw thread rotation direction at shank during use, just can twist bolt or nut, spanner is usually with structural carbon steel or alloy structure steel making.

Common spanner is difficult to screw is screwed down, and need to knock screw by external force, easily skids, even can twist instrument curved or twist into two parts, and not flexible is not easy to carry, and common functions of wrench is single, when running at work different workpiece, need multiple types of tools, operation inconvenience affects operating efficiency, if wrench breaks down, cisco unity malfunction then.

The utility model content

The purpose of this utility model provide a kind of can dual-purpose and telescopic spanner, in order to solve the defective that exists in the prior art.

The utility model is achieved through the following technical solutions.

A kind of multi-functional torque spanner comprises ratchet 7, extendable handle and groove 3, and described extendable handle comprises interior handle 2 and outer handle 6; Outer handle 6 terminations are provided with bayonet socket 4; The port that interior handle 2 can insert in the outer handle 6 is provided with card joint 5, and the bottom of outer handle 6 offers with securing member and twists the groove 3 that solid position shape is complementary, and the top of described interior handle 2 is connected with take pin 1 as axle along the ratchet 7 of interior handle 2 rotations by pin 1.

The cross sectional shape of described groove 3 is circle or hexagon, and is consistent with the shape size of screw or nut fastener.

The thickness of described outer handle 6 is more than or equal to the longest edge of groove 3.

A kind of multi-functional torque spanner of the utility model, extendable handle comprises interior handle 2 and outer handle 6; Outer handle 6 terminations are provided with bayonet socket 4; The port that interior handle 2 can insert in the outer handle 6 is provided with card joint 5, realize the length of folding and unfolding handle, it is comparatively convenient to use, carry, the bottom of outer handle 6 offers with securing member and twists the groove 3 that solid position shape is complementary, so that twisting solid position, securing member can fall into groove, multiaspect while, uniform stressed, easy to use, effective, so that the function of spanner is no longer single.
