Abstract

Opening V type spanner, including the spanner handle, a side -mounting wrench body of spanner handle, first fixed slot is offered to one side of a wrench body, and one side of first fixed slot sets up first fundamental plane, and the opposite side of first fixed slot sets up first sawtooth plane, and first fundamental plane place plane and the planar contained angle in first sawtooth plane place are alpha, 20 <= alpha <= 50, the utility model discloses a first fundamental plane place plane and the planar contained angle in first sawtooth plane place be alpha, 20 <= alpha <= 50, make first sawtooth plane and first fundamental plane can be closely with twisted the thing and cooperated to avoid opening V type spanner to twist the thing slippage with the quilt when twisting by wrong thing.

Description

Opening V-type spanner

Technical field

The utility model relates to a kind of spanner, more precisely a kind of opening V-type spanner.

Background technology

Traditional opening or double offset ring spanner, can only be used for stubborn square, hexagonal or bihexagonal nut, workpiece or the nut of other shape cannot be turned, particularly when stubborn rusted-on nut, the profile of nut can be damaged, finally cannot turn on nut, even damage whole equipment, and traditional spanner operating efficiency and low, after completing and once rotating, cannot carry out fast and continuous print turns operation, can only the work of the method clumsiness of taking out from nut, putting back to once.Tradition opening or double offset ring spanner spanner generally can only twist the nut of two sizes, and maintenance mans and operator generally need to be with a lot of specification spanner to be applicable to operation.Subtended angle between the first foundation plane of existing spanner and the first serration plane arranges unreasonable, twist by during stubborn thing easily with by stubborn thing slippage.

Utility model content

The purpose of this utility model is to provide a kind of opening V-type spanner, can solve the above problems.

The utility model for achieving the above object, is achieved through the following technical solutions:

Opening V-type spanner, comprise spanner handle, the first wrench body is installed in the side of spanner handle, the first holddown groove is offered in the side of the first wrench body, the side of the first holddown groove arranges first foundation plane, the opposite side of the first holddown groove arranges the first serration plane, the angle of first foundation plane place plane and the first serration plane place plane is α, 20 °≤α≤50 °, the opposite side of spanner handle installs the second wrench body, the second holddown groove is offered in the side of the second wrench body, the side of the second holddown groove arranges the second basic plane, the opposite side of the second holddown groove arranges the second serration plane, the angle of the second basic plane place plane and the second serration plane place plane is β, 20 °≤β≤50 °.

The utility model has the advantage of: the angle of first foundation plane place plane of the present utility model and the first serration plane place plane is α, 20 °≤α≤50 °, first serration plane and first foundation plane closely with by stubborn thing can be coordinated, thus avoid opening V-type spanner stubborn by during stubborn thing and by stubborn thing slippage.The spanner of three models be made up of the utility model just can twist the pipeline within the scope of multiple caliber, thus it is too many and cause the waste of space and cost to decrease spanner specification.The utility model due to design angle α and the first serration plane cooperation, achieve the function of available quick use, make to improve efficiency greatly at work.Owing to being one-object-many-purposes, compared to conventional spanner, save production cost and raw material greatly, one has also been made to the saving of social resources and has contributed greatly.Second wrench body of the present utility model can assist the first wrench body operation.The utility model also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings: Fig. 1 is structural representation of the present utility model.

Mark parts: 1 first foundation plane 2 first serration plane 3 first wrench body 4 first holddown groove 5 spanner handle 6 second wrench body 7 second basic plane 8 second serration plane 9 second holddown groove.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.

Opening V-type spanner, as shown in Figure 1, comprise spanner handle 5, the first wrench body 3 is installed in the side of spanner handle 5, the first holddown groove 4 is offered in the side of the first wrench body 3, the side of the first holddown groove 4 arranges first foundation plane 1, the opposite side of the first holddown groove 4 arranges the first serration plane 2, the angle of first foundation plane 1 place plane and the first serration plane 2 place plane is α, 20 °≤α≤50 °, the opposite side of spanner handle 5 installs the second wrench body 6, the second holddown groove 9 is offered in the side of the second wrench body 6, the side of the second holddown groove 9 arranges the second basic plane 7, the opposite side of the second holddown groove 9 arranges the second serration plane 8, the angle of the second basic plane 7 place plane and the second serration plane 8 place plane is β, 20 °≤β≤50 °.

The angle of first foundation plane 1 place plane of the present utility model and the first serration plane 2 place plane is α, 20 °≤α≤50 °, first serration plane 1 and first foundation plane 2 closely with by stubborn thing can be coordinated, thus avoid opening V-type spanner stubborn by during stubborn thing and by stubborn thing slippage.The spanner of three models be made up of the utility model just can twist the pipeline within the scope of multiple caliber, thus it is too many and cause the waste of space and cost to decrease spanner specification.The utility model due to design angle α and the first serration plane 1 cooperation, achieve the function of available quick use, make to improve efficiency greatly at work.Owing to being one-object-many-purposes, compared to conventional spanner, save production cost and raw material greatly, one has also been made to the saving of social resources and has contributed greatly.Second wrench body 6 of the present utility model can assist the first wrench body 3 to operate.

The number of degrees of described α are 20 ° or 24 ° or 27 °.Through experimental verification, when the number of degrees of α be 20 ° or 24 ° or 27 ° time the first serration plane 1 and first foundation plane 2 can be made more closely with by stubborn thing to coordinate, thus avoid opening V-type spanner twist by during stubborn thing with by stubborn thing slippage

The number of degrees of described β are 18 ° or 24 °.Through experimental verification, when the number of degrees of β be 18 ° or 24 ° time, time the second serration plane 8 and the second basic plane 7 can be made more closely with by stubborn thing to coordinate, thus avoid opening V-type spanner twist by during stubborn thing with by stubborn thing slippage

Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
