Abstract
Multifunctional double-headed special-shaped fork spanner.The utility model belongs to hand-operated tools class, is specifically related to a kind of double ended spanner of improvement.At existing handle bar two ends, button is set, on the fork spanner basis that jaw size on each button is different, improve as follows: the outer jaw and the internal clamp port that each button are provided with hierarchic structure, the outer jaw of equidirectional and internal clamp port have a public working face, and the discrepancy in elevation of outer jaw and internal clamp port ladder working face is 2mm.The utility model structure is simple, often spanner can be carried out degree of tightness operation to the nut of four kinds of different models or bolt, can prevent from skidding in use, also can avoid the potential safety hazard of work high above the ground.
Description
Technical field
The utility model belongs to hand-operated tools class, is specifically related to a kind of double ended spanner of improvement.
Background technology
Now can carry out degree of tightness operation to the nut of two kinds of different models or bolt with double ended spanner, the little convolution surplus of spanner button is large, and comparatively monkey wrench has more flexibility.During current each main equipment assembling, outer-hexagonal bolt consumption is large, and same equipment bolt model used when assembling is not of uniform size, need carry a large amount of spanner when carrying out assembling or overhauling.As the connection of flange face, when assembly precision is less demanding, because bolt (nut) exists the difference of standard and nonstandard standard, may occur that nut is worn or the situation of size not easily identification by mistake, common double ended spanner is used if continue, then can cause situation about taking time and effort, when firmly excessive, there will be slip, cause outer-hexagonal bolt or nut angle crest line impaired, decrease bolt service life, and when work high above the ground, now exist with double ended spanner and put inconvenient situation, easily drop and hurt sb.'s feelings or hinder equipment.
Known by as above analyzing, the double ended spanner that existing market generally uses, can only be used for nut or the bolt of two kinds of different sizes, assembling or maintenance is caused to take time and effort, can produce slip when unscrewing or screw and cause nut or bolt damage, and inconvenience is put in existence, easily causes potential safety hazard.
Utility model content
For the shortcoming of existing double ended spanner, technical problem to be solved in the utility model is to provide a kind of multifunctional double-headed special-shaped fork spanner, its structure is simple, often spanner can be carried out degree of tightness operation to the nut of four kinds of different models or bolt, can prevent from skidding in use, also can avoid the potential safety hazard of work high above the ground.
The technical scheme that the present invention takes is: arrange button at existing handle bar two ends, on the fork spanner basis that jaw size on each button is different, improve as follows: the outer jaw and the internal clamp port that each button are provided with hierarchic structure, the outer jaw of equidirectional and internal clamp port have a public working face, and the discrepancy in elevation of outer jaw and internal clamp port ladder working face is 2mm.
The jaw opening direction that described handle bar two ends are arranged and handle bar longitudinally become the angle of ± 13 ~ 18o.
Have the chamfering of 110 ~ 130 ° between the stepped working face of described inside and outside jaw, permanent magnet coating is equipped with in the side of handle bar.
The corresponding bolt of jaw and internal clamp port or the position of nut angle crest line are processed with the stressed groove of friction outside; Bossed locating dowel inside permanent magnet coating, locating dowel is stuck in the locating slot of correspondingly-shaped on handle bar.
The beneficial effects of the utility model are: a double ended spanner can be operated for the nut of four kinds of various criterion sizes or bolt; The setting of stressed groove of rubbing solves fork spanner and skids and cause nut or the impaired phenomenon of bolt crest line; After installing Magnetic adhesive mat additional, spanner can be adsorbed in metal surface, not easily drops and hurts sb.'s feelings or hinder equipment.During design, button and handle are done size and are met GB/T4388 and GB/T4389 given size, maintain the flexible nature that the revolution space of common double ended spanner is little, and to make to unscrew or screw more time saving and energy saving simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be permanent magnet coating of the present utility model with handle bar in conjunction with schematic diagram.
In figure: outer jaw 1, button 2, permanent magnet coating 3, handle bar 4, stressed groove 5, internal clamp port 6, locating slot 7, locating dowel 8, public working face 9.
Detailed description of the invention
See each figure, this fork spanner comprises double-handle head 2 and handle bar 4, each button 2 is provided with outer jaw 1 and the internal clamp port 6 of hierarchic structure, and the outer jaw 1 of equidirectional and internal clamp port 6 have a public working face 9, and outer jaw 1 is 2mm with the discrepancy in elevation of internal clamp port 6 ladder working face.The jaw opening direction that handle bar 4 two ends are arranged and handle bar longitudinally become the angle of ± 13 ~ 18o.Have the chamfering of 110 ~ 130 ° between the stepped working face of inside and outside jaw, permanent magnet coating 3 is equipped with in the side of handle bar 4.The corresponding bolt of jaw 1 and internal clamp port 6 or the position of nut angle crest line are processed with the stressed groove 5 of friction outside; Bossed locating dowel 8 inside permanent magnet coating 3, locating dowel 8 is stuck in the locating slot 5 of correspondingly-shaped on handle bar 4.
With 19 × 17, the special-shaped fork spanner of 18 × 16 double ends is designed to example: the button 19 × 17 and 18 × 16 being distributed in handle bar two ends is mutually 15 ° of angles with handle bar respectively, the internal clamp port of width to be the outer jaw of 19mm and width be 17mm is 2mm by vertical missing, and it is stepped that chamfering is that the inclined plane of 120 ° connects into; The torsion groove inside sinking into jaw surfaces by radius be three of 1mm connected in connect equilateral triangle and connected and composed by the rounding that radius is 0.2mm, depth of rebate is determined by the distance size of survey calculation nut (bolt) opposed apexes, and the jaw design process of 18 × 16 and jaw are 19 × 17 identical; Magnetic adhesive mat by thick be 1mm, wide is 4.6mm, and being evenly distributed with is highly three cylindrical projection composition of 1.5mm, interiorly during assembling sinks into the dry surface of handle.
