CN201728622U - Novel wrench - Google Patents

Abstract

The utility model relates to a wrench, in particular to a novel wrench. The utility model aims to providing the novel wrench which has the advantages of simple and practical structure and saves labor when in use. The technical scheme is that the novel wrench comprises a wrench head and a handle, the rear end of the handle is movably connected with an extension rod through a connecting piece, the extension rod can rotate around the connecting piece, the handle at the rear end of the connecting is fixedly connected with a fixed column, and when the extension rod rotates to the position of the fixed column, the fixed column can stop the extension rod. The extension rod is a retractable structure which is formed by a plurality of sections which are movably connected. When all sections of the extension rod are compressed together, the extension rod can be rotatably placed in a groove which is arranged on the handle. The utility model is simple, convenient and practical.

Description

A kind of novel spanner

Technical field

The utility model relates to a kind of spanner, particularly relates to a kind of novel spanner that can increase moment when exerting oneself.

Background technology

Spanner in the middle of the prior art all is made up of spanner and handle, in order to adapt to the needs of various occasions, the size of spanner is had any different, but shape is all similar, main shortcoming is, under the situation of the big strength ability of needs cost rotating spanner, because the handle of spanner is generally all very short, so the strength that applies will greatly much could be rotated comparatively speaking, according to lever principle, if can add long handle this moment, so Hua Fei strength will be little a lot, very easily just can turning handle, basically we borrow power at the thing that can try every possible means to put steel pipe and so on handle, but such mode is very inconvenient after all, and for a lot of than relatively large or very little spanner, just more impossiblely take this mode.

The utility model content

The purpose of this utility model provides a kind of novel spanner, and is simple and practical, uses more laborsaving.

The purpose of this utility model realizes by following technical proposal: a kind of novel spanner, comprise spanner and handle, the rear end of described handle is connected with an extension bar by a connector, extension bar can rotate around connector, be fixedly connected with a fixed leg on the handle of connector rear end, when extension bar turned to the position of fixed leg, fixed leg can stop extension bar.

Described extension bar is that multi-segment structure flexibly connects the telescopic structure form, when each section of extension bar is compressed together, can rotates and is positioned in the groove of offering on the handle.

From architectural feature of the present utility model as can be seen, advantage of the present utility model is: by add an extension bar on handle, in use extension bar is taken out from groove, rotating lengthening bar, extension bar under the opposition of fixed leg, turning handle, also just be equivalent to handle is extended, more laborsaving, and extension bar can stretch, and selects the length that is fit to as required, when not needing to use, only extension bar need be withdrawn, be placed in the groove and get final product simple and convenient practicality.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Wherein Reference numeral 1 is that spanner 2 is that handle 3 is that connector 4 is extension bars

The 5th, fixed leg 6 is grooves.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Preferred embodiment

A kind of novel spanner as shown in Figure 1, comprise spanner 1 and handle 2, the rear end of described handle 2 is connected with an extension bar 4 by a connector 3, extension bar 4 can rotate around connector 3, be fixedly connected with a fixed leg 5 on the handle 2 of connector 3 rear ends, when extension bar 4 turned to the position of fixed leg 5, fixed leg 5 can stop extension bar 4.

The telescopic structure that described extension bar 4 forms for multi-segment structure flexibly connects when each section of extension bar 4 is compressed together, can be rotated and is positioned in the groove of offering on the handle 26.

Disclosed all features in this specification except mutually exclusive feature, all can make up by any way.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
