Abstract

A multifunctional adjustable spanner features that the internal surface of the head of its tap has 6-10 arc tooth shapes, one end of its spanner body has 14-18 arc tooth shapes, and the tap and spanner body are connected via rivet and spring. The adjustable spanner has the advantages that a screw mechanism of the adjustable spanner is not required to be twisted and adjusted when the adjustable spanner is used, the fastening piece and the circular pipe fitting can be automatically clamped and loosened, and the functions of the adjustable spanner and the pipe wrench are combined into a whole, so that the operation time is saved, the working efficiency is improved by 8-10 times, the operation is simple, and the adjustable spanner is particularly convenient and superior to use under the conditions of high-altitude operation and poor vision.

Description

Multifunction shifting spanner

The utility model relates to a kind of multifunctional adjustable spanner, belongs to hardware ﹠ tools, mainly is to be used for fastening and loosening fasteners.

Existing adjustable wrench need twist and adjust the screw mechanism of adjustable wrench according to its different size fastening and when unclamping six sides, cubic securing member with hand, not only time-consuming but also effort, and also it is particularly inconvenient to work under the condition of high-altitude application and sight equation; It is fastening and unclamp the round tube component that existing in addition adjustable wrench can not be used for, and function ratio is more single, and fastening and also must use pipe vice when unclamping the round tube component, and existing pipe vice heaviness is relatively extremely required great effort during use.

The purpose of this utility model is to overcome the shortcoming of existing adjustable wrench, provide a kind of by tap, pull that body, spring etc. form both can be used for fastening and unclamp six sides, cubic securing member, can be used for fastening and the multifunctional adjustable spanner that unclamps the round tube component again.

The purpose of this utility model realizes with following scheme:

It is 60 ° that the inner portion surface of tap is shaped on 6-10 addendum angle--65 ° circular arc profile of tooth has two disjunct through holes at the head other end; Also being shaped on 14-18 addendum angle with corresponding that end face of pulling body of tap head is 60 °--65 ° of circular arc profiles of tooth, and pull and also have two disjunct through holes on the body; Tap with pull body and adopt rivet and spring to be connected respectively by its two two through hole.

The advantage that the utlity model has is:

1, the utility model not only can be used for fastening and had unclamped six sides, cubic securing member but also can be used for fastening and unclamp the round tube component, and it unites two into one the function of existing spanner alive and pipe vice, has enlarged function of use.

2, the utility model is fastening and when unclamping the different size securing member, no longer need to twist and adjust the screw mechanism of adjustable wrench, energy automatic card-loading and relieving, use freely, easy and simple to handle, save time, operating time only is 1/10 of an existing adjustable wrench, the 8--10 that increases work efficiency doubly uses under the condition of high-altitude application and sight equation, and is particularly convenient and superior.

3, the utility model is compared with existing pipe vice, and its weight is the 1/5--1/6 of pipe vice only, has overcome use pipe vice heaviness, uses the deficiency of effort.

Description of drawings:

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

Fig. 2 is that the A-A of Fig. 1 is to diagrammatic sketch.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

It is 60 °-65 ° circular arc profile of tooth 2 that tap 1 inner portion surface is shaped on 6-10 addendum angle, has a φ 6 through holes 11 and φ 2 through holes 5 at the head other end; Pull body 8 also to be shaped on 14-18 addendum angle with corresponding that end face of tap head be 60 °--65 ° circular arc profile of tooth 3, have a φ 6 through holes 10 with the leading through hole 11 corresponding body regions of pulling, pull the body front middle part and have a φ 2 through holes 7, pull the body other end and have a hexagonal through hole 9; Tap with pull through hole 11 and the through hole 10 of body by its end and adopt rivets 4 and each through hole 5 and through hole 7 to adopt springs 6 to be connected and fixing separately.

Tap by spring can activity freely, itself and pull six sides that can tighten and decontrol the M8--M35 different size between the body head automatically, cubic securing member and φ 10-φ 35 round tube components, after securing member and round tube component tighten automatically, pull body and just can reach fastening and purpose that unclamp six sides, cubic securing member and round tube component.The six square tube holes of pulling body one end can also be as fastening and unclamp a kind of specification six side's securing members and use.

Claims (1)

1, a kind of multifunctional adjustable spanner is made up of tap, plate body, spring etc., it is characterized in that:

1. to be shaped on 6-10 addendum angle be 60 °-65 ° circular arc profile of tooth on Long Tou inner portion surface, has two disjunct through holes at the head other end;

2. with corresponding that end face of pulling body of tap head, also being shaped on 14-18 addendum angle is 60 °--65 ° of circular arc profiles of tooth, and pull and also have two disjunct through holes on the body;
