Description

A kind of novel portable box spanner

Technical field

This utility model belongs to electric power tool technical field, particularly relates to a kind of novel portable box spanner.

Background technology

Current existing box spanner is substantially lower than connected face for nut end or bolt end, and the diameter of shrinkage pool cannot be used for open-end wrench or adjustable wrench and double offset ring spanner, just with box spanner, is exactly additionally the restriction of bolt part space, also can only use box spanner. Box spanner is commonly referred to as sleeve: it is by multiple sleeves with hexagon ring or 12 corner apertures and is furnished with the multiple accessories such as handle, extension bar and forms, and is particularly well-suited to twist that status is very narrow and small or the bolt of depression very deep or nut. Sleeve have metric system and English system point, although sleeve concave shape is the same, but external diameter, length etc. are the shape and size for corresponding device design, and country does not have Uniform provisions, so the design of sleeve is relatively more flexible comparatively speaking, meets popular needs. Box spanner generally all has the collet head of a set of all size and handle of waving, extension bar, universal joint, driver joint, elbow handle etc. for being inserted in hexagonal (hexagon)nut. The collet head of box spanner is a recessed hexagonal cylinder; Spanner is generally made up of carbon structural steels or structural alloy steel, and Wrench head has the hardness of regulation, and middle and handle portion then has elasticity. Having a wide range of applications in the technological processes such as automobile assembling intermetallic composite coating, but existing box spanner often only one of which sleeve and pinch bar, and when using, pinch bar direction of bolting on is fixed, and works long hours and easily affects its life-span.

China Patent Publication No. is CN104416511U, the name that utility model is created is called box spanner, including box spanner body, four-way transition joint, pinch bar, buffer protection set and sleeve, it is characterized in that: described four-way transition joint up and down four be connected to identical pinch bar simultaneously, described four-way transition joint is connected with pinch bar one end female thread; Described buffer protection set is enclosed within the end of the pinch bar other end, and described buffer protection set is fixing with pinch bar to be connected;The described pinch bar other end is additionally provided with sleeve, and described sleeve is connected with pinch bar female thread. But existing box spanner also exists is inconvenient to carry, the problems such as dismounting nut kind is few.

Therefore, a kind of novel portable box spanner of invention seems very necessary.

Utility model content

In order to solve above-mentioned technical problem, this utility model provides a kind of novel portable box spanner, also exists and is inconvenient to carry solving existing box spanner, the problems such as dismounting nut kind is few. A kind of novel portable box spanner, including receiver, socket bar, collet head and boosting-rod, described receiver includes receiver A and receiver B, described receiver A totally two, is separately positioned on the upper and lower both sides of receiver; Described receiver B totally two, is separately positioned on the receiver left and right sides; Described socket bar is plugged in receiver A; Described collet head is plugged in socket bar; Described boosting-rod is plugged in receiver B.

Six prismatic holes it are provided with in described receiver A.

It is provided with circular port in described receiver B.

Described socket bar is six prismatic cylinders near receiver side, and side is provided with six prismatic holes, it is only necessary to a socket bar, only need to change the collet head needing to use and can meet requirement, make dismounting more convenient, and it is more convenient to carry.

Described collet head adopts top to be set to interior hexagonal or the outer-hexagonal head that diameter is 1 centimetre to 40 centimetres, makes dismounting kind more, expands use scope, reduces maintenance cost so that easy to use.

The outer surface of described boosting-rod is provided with rubber layer, can increase friction, operating personnel can be made more comfortable in cold winter again.

Described socket bar is two, it is possible to carries out grafting, the length of lengthening sleeve when needs, adapts to different environment.

Compared with prior art, this utility model has the advantages that owing to a kind of novel portable box spanner of the present utility model is widely used in electric power tool technical field. Meanwhile, the beneficial effects of the utility model are:

1. the setting of this utility model socket bar, side is six prismatic cylinders, and side is provided with six prismatic holes, it is only necessary to a socket bar, only need to change the collet head needing to use and can meet requirement, make dismounting more convenient, and it is more convenient to carry.

2. the setting of collet head of the present utility model, makes dismounting kind more, expands use scope, reduces maintenance cost so that easy to use.
