Description
Technical field
The present invention is relevant with the muff joint of penetration spanner, this sleeve has a horn shape junction surface and is set in the ratchet or polygonal trepanning of enclosed type spanner, this horn shape junction surface ring is established a groove, establish a metal wire in this groove, this metal wire makes horn shape junction surface and the ratchet of spanner or the positioning relation that polygonal trepanning forms 3 tight systems of this sleeve, and this muff joint can more securely combine with various enclosed type spanners.
Background technology
As Fig. 1 to Fig. 3, a kind of known muff joint 10 of expression among the figure, this muff joint 10 comprises a horn shape junction surface 11, and the sleeve part 12 that connects of one with it.The outline at this horn shape junction surface 11 has comprised some limits 112, and the end angle 111 between each limit 112.This horn shape junction surface 11 is set in the ratchet 21 of plum blossom ratchet spanner 20 as shown in the figure.
Above-mentioned horn shape junction surface 11 rings are established a groove 13, establish a metal wire 30 in this groove 13.This metal wire 30 anchor line (string) type metal one bending, has one first stretch section 31, this first stretch section 31 connects one second stretch section 33 with first turnover 32, this second stretch section 33 connects one the 3rd stretch section, 35, the three stretch sections 35 with second turnover 34 and connects one the 4th stretch section 37 with the 3rd turnover 36.These horn shape junction surface 11 rings are established a groove 13, this metal wire 30 is located in this groove 13, abut against the inboard cell wall 131 of this groove 13 with its first, second, third stretch section 31,33,35, and make first, second and third turnover 32,34,36 radially protrude wherein three limits 112 at this horn shape junction surface 11.
Above-mentioned horn shape junction surface 11 has six end angles 111 and six limits 112, and metal wire 30 radially protrudes wherein three limits 112 at this horn shape junction surface 11 with its first, second and third turnover 32,34,36, therefore on the profile at this horn shape junction surface 11, has the structure of nine horn shape evaginations, so above-mentioned ratchet 21 is to have 12 ratchets 23 and 12 sample attitudes that ratchet slot 22 is the best, because all end angles 111 and all turnover 32,34,36 all are sticked in the ratchet slot 23, and ratchet 21 is combined with muff joint 10.Meaning promptly combines the spanner that cooperates with known sleeve, must have suitable majority ratchet slot 22 could with above-mentioned known muff joint assembly.So the spanner of the above-mentioned ratchet slot 22 of tool can't not joined with known muff joint and be answered.
The scarce fraud of above-mentioned metal wire 30, it only is to be linked in the groove 13 at this horn shape junction surface 11, though this first, second, third stretch section 31,33,35 abuts against the inboard cell wall 131 of this groove 13, must fail to make this metal wire 30 to be in a motionless position unexpectedly.In other words, when metal wire 30 is incorporated into double offset ring spanner with ratchet, this metal wire 30 is subjected to the ratchet radial compression power of ratchet, can in this groove 13, rotate or slide, and make this first, second, third turnover 32,34,36 leave original position, and may make the improper extruding of its ratchet that is subjected to ratchet and be out of shape, this will make the fixed effect effect forfeiture of metal wire 30.
Summary of the invention
The objective of the invention is to, a kind of muff joint of penetration spanner is provided,, reach the purpose of handled easily, use to overcome the defective of above-mentioned traditional structure.
The muff joint of penetration spanner of the present invention, this muff joint have a horn shape junction surface and are set in the ratchet or polygonal trepanning of spanner, and this horn shape junction surface ring is established a groove, and this groove is established a locating hole; Ring is established a metal wire in this groove, this metal wire one end is fixed in this locating hole, make the ratchet of this horn shape junction surface and spanner or the positioning relation that polygonal trepanning forms 3 tight systems, muff joint can securely be set in the ratchet or polygonal trepanning of various enclosed type penetration spanners.
One of effect of the present invention, muff joint of the present invention can be used with various case type spanner assembly, joins the more known muff joint height of answering property.So-called enclosed type spanner, for example plum blossom ratchet spanner, double offset ring spanner, polygonal spanner, internal tooth ratchet spanner ... Deng.First, second turnover of the metal wire of muff joint of the present invention can be fastened on along with the end angle at its horn shape junction surface in the end angle of the ratchet slot of these spanners or polygonal trepanning, and the function of performance elasticity blocking.
Two of effect of the present invention, the metal wire of muff joint of the present invention not only is linked in the groove at this horn shape junction surface, it more colludes solid in being attached to the locating hole of this muff joint with a hook part, this metal wire obtains the location, in groove, do not slide, its first, second permanent wherein two end angles with respect to this horn shape junction surface of turnover, this correspondence position can change.
Three of effect of the present invention, the metal wire of muff joint of the present invention is sleeved in the groove at this horn shape junction surface, and colludes with its hook part and to be fixed in this locating hole, and an end that forms this metal wire is fixed, and the other end is state freely.This state makes this metal wire have the ability of elasticity hypertonic, help muff joint successfully with spanner in conjunction with or separate.
Four of effect of the present invention, the horn shape junction surface assembly of muff joint of the present invention is in the polygonal spanner of enclosed type, first and second turnover of this metal wire is embedded in the end angle of this ratchet slot or trepanning, constitute two blocking points, and make this horn shape junction surface become the position of triangle relation to be tight against the ratchet or the trepanning of spanner with these two blocking points, form the positioning relation of 3 tight systems, this muff joint promptly firmly is positioned in the spanner.
Five of effect of the present invention, the horn shape junction surface one of muff joint of the present invention connects a sleeve, and this sleeve center is one jiao of hole, and a circular hole that axially connects this horn shape junction surface is communicated to this hole, angle.In view of the above, muff joint of the present invention can be passed for a stay bolt at work, is positioned on the nut of stay bolt than the position, deep and sleeve must be socketed in, and reaches the purpose of handled easily, use.
