Abstract

A spanner comprises a handgrip part and a sleeve part. The handgrip part is integrated with the sleeve part into one piece. The spanner is characterized in that the end of the handgrip part is provided with a protrudent optical axis; the sleeve part is cylindrical shaped; the inner bore of the sleeve part is an inner hexagonal clear opening. The spanner is simple in structure, convenient to operate, reliable in performance, and cheap in price, which can screw on or off nuts quickly and conveniently. The spanner is not required to be operated by a professional, which is a very economical spanner.

Description

A kind of spanner

Technical field

The utility model relates to an instrument, particularly a kind of spanner that is used for the securing member degree of tightness.

Background technology

Instrument of the prior art more and more spreads in each family; some common tools particularly; in the middle of life, often have some electrical equipment and meet some minor issues; and to deliver to repair shop's trouble very; what can oneself solve generally all can oneself solve; just require instrument easy this moment; flexibly; more convenient like this user uses; when some industry are used also is like this; the spanner that on some immersible pumps, uses particularly; require its convenient use especially; but this spanner of the prior art is complex structure mostly; the manufacturing cost height; operate dumbly, as the disclosed patent No. of Chinese patent be: 86102033 are called: the patent of invention of monkey wrench, and it adopts by the ring spanner movable part that can planar swing and assigns to vise securing member; regulate swinging axle and realize regulating the opening and closing size; its complex structure of this spanner, the manufacturing cost height uses very inconvenient; the limited place in some spaces particularly, this spanner can't launch to use at all.

The utility model content

For solving spanner weak point of the prior art, provide a kind of simple in structure, good reliability, spanner easy to use.

For addressing the above problem, spanner of the present utility model, comprise an one handle part and a sleeve part, described handle portion is connected in aggregates with the sleeve part, it is characterized in that: described handle portion has an outstanding optical axis at tail end, described sleeve part profile is a cylinder, and described sleeve part endoporus is a hexagonal through hole in.

Compared with prior art, spanner of the present utility model adopts hexagonal through hole in sleeve part built-in, so just is very easy to match with securing member, can all be inserted in the hex nut, so just enlarged stress point, avoided occurring the phenomenon of slip teeth, the peripheral cylindrical structural that adopts, it can be inserted in hex nut at each position very flexibly, its handle portion has an outstanding optical axis, so just can prevent effectively that spanner slips from hand firmly the time, has certain anti-skidding effect.

Description of drawings

Below in conjunction with the drawings and specific embodiments spanner of the present utility model is described further:

Fig. 1 is the cross-sectional schematic of spanner of the present utility model;

Fig. 2 is the schematic top plan view of spanner of the present utility model.

Among the figure:

Hexagonal through hole in 1 sleeve part 2

3 handle portions, 4 outstanding optical axises

The specific embodiment

As depicted in figs. 1 and 2, spanner of the present utility model comprises an one handle part 3 and a sleeve part 1.

As depicted in figs. 1 and 2, handle portion 3 outer ends are a cylindrical structural, and handle portion 3 the inners are hexagonal through hole 2 in, also have a chamfering (not shown) at the two ends of interior hexagonal through hole 2.The outer end of cylindrical structural is in order to save material on the one hand, be in the space of required work, to rotate more flexibly on the other hand, interior hexagonal through hole 2 in handle portion 3 the inners is in order to match with hex nut, it can be inserted in and enlarge stress point in the hex nut, avoids taking place slip teeth, beats the tooth phenomenon.

As depicted in figs. 1 and 2, at handle portion 3 an outstanding optical axis 4 is arranged, the setting of outstanding optical axis 4 is for anti-skidding, when in work, can occur some lubricants of wet goods on hand unavoidably, this moment, outstanding optical axis 4 just can prevent effectively that spanner from from skidding off on hand, having avoided the generation of some accidents.

Description according to its structure, it is very simple to draw its structure of spanner of the present utility model, low cost of manufacture, economic performance is good, very easy to use, particularly its stress point area is big, has avoided slip teeth, has beaten the tooth phenomenon, be particularly suitable for the degree of tightness of some pump top nuts, so it have very large market prospects.

According to embodiment of the present utility model to being illustrated property of the utility model and nonrestrictive description; but should understand; under the situation that does not break away from relevant protection domain defined by the claims, those skilled in the art can make change and/or revise.

Claims

1, a kind of spanner, comprise an one handle part and a sleeve part, described handle portion is connected in aggregates with the sleeve part, it is characterized in that: described handle portion has an outstanding optical axis at tail end, described sleeve part profile is a cylinder, and described sleeve part endoporus is a hexagonal through hole in.
