Abstract

The utility model discloses an improved spanner with new structure and return function on the basis of adjustable spanners and solid spanners. The aim of the spanner is to cause the exiting adjustable spanners and the solid spanners to have wide application compared with the exiting ratchet spanners besides the functions of the ratchet spanners, and for example, components need not to be replaced when using, and screw nuts and screw bolts which are not positioned at top end can be fastened. The utility model can be entirely redesigned, and also the adjustable spanner openings of the exiting adjustable spanners are redesigned with simple production and effective use.

Description

Easy-to-use spanner

The utility model is a kind of improved on the basis of adjustable wrench and fork spanner, and the spanner of the new structure of the function of rewinding can be arranged as ratchet spanner.

Existing adjustable wrench and fork spanner all will repeatedly be thrown off securing member when clamp nut and bolt, will go repeatedly to align like this, not only require great effort at running hours, and efficient are low.Existing ratchet spanner is complex structure comparatively speaking, and will be constantly when using Change parts more, so use also not too convenient.The purpose of this utility model is to make existing adjustable wrench, fork spanner have the function of ratchet spanner, and than existing ratchet spanner purposes is widely arranged, when using without Geng Change parts, can fastening non-top nut bolt.

Key of the present utility model is a draw key to be installed rewind mechanism on the spanner mouth, promptly a draw key (1) is housed rewinding on the tooth (3), and one makes the fixedly pin of draw key (4) of compression spring (2) that draw key resets and.Rewind tooth and draw key is slidingly matched.When clamp nut, draw key is pressed in the normality position by spring, and spanner can come clamp nut with this with hex nut two parallel planes that are coupled like this.When rewinding spanner, nut can and rotate in spanner draw key (1) jack-up, thereby needn't break away from nut to spanner, can fastening continuously (loosening) nut, bolt.

The utility model is compared with known, is characterized in combining the advantage of adjustable wrench and ratchet spanner, and is easy to use, simple in structure.

Fig. 1, Fig. 2 are improved embodiment of the present utility model on the basis of adjustable wrench (duties fastening, when loosening securing member that Fig. 1, Fig. 2 are respectively), mainly by draw key (1), compression spring (2), rewind tooth (3), pin (4) is formed, and draw key (1) and rewinding between the tooth (3) is slidingly matched.The utility model also can derive several spanners, as shown in Figure 7, improved spanner on the fork spanner basis, (1), (2) among Fig. 7, (3), (4) are identical with title among Fig. 1.

Above-mentioned two kinds of embodiment are through probationary certificate, and are simple in structure, easy to use, promptly improved operating efficiency, alleviated work Strong degree again.

Claims

1, a kind of on the basis of adjustable wrench or fork spanner the improved Easy-to-use spanner that the function of rewinding is arranged, it is characterized in that on the spanner mouth, having installed a draw key and rewind mechanism.

2, it is characterized in that by the described spanner of claim 1 draw key rewinds mechanism and is made up of a draw key (1), compression spring (2) and a pin (4).

3, it is characterized in that by claim 1,2 described Easy-to-use spanners draw key is rewinded mechanism to be installed in and to rewind on the tooth (3), rewind between tooth (3) and the draw key (1) to be slidingly matched.
