Description

Speeder wrench

Technical field

The utility model is disclosed to be a kind of speeder wrench, especially a kind ofly can lock the speeder wrench that unloads to nut apace, belongs to hardware ﹠ tools.

Background technology

Spanner is that the specific purpose tool that unloads bolt and nut is locked in not strange being used to of people, and comparatively common spanner roughly is divided into two big classes in the prior art, and a class is an adjustable wrench, and another kind of is fork spanner.No matter but be adjustable wrench, still fork spanner is in the process of lock removing nut, as being example with locking, whenever revolved certain angle, the jaw mouth of spanner must be recessed nut once, and then make the jaw mouth aim at nut, angle of switching again, so repeatedly, until nut check, it is the same to unload the mode that opens (pine is opened) nut, and the action direction of different is spanner is opposite.From the above, no matter be locking nut, or pine opens nut, and its operating efficiency is very low.

Summary of the invention

Task of the present utility model is will provide a kind of can lock the speeder wrench that unloads to nut apace.

Task of the present utility model is finished like this, a kind of speeder wrench, it comprises a pedestal 1, centre tool commutation board cavity volume 35 among the pedestal 1, the chamber wall Zhou Buyou gear ring 2 of commutation board cavity volume 35, gear ring 2 tops are formed with fluted disc chamber 19, wall has extended one handle Connection Block 36 outside the pedestal 1, the centre is a ratch hole 13 among this handle Connection Block 36, ratch hole 13 penetrates into 19 places, described fluted disc chamber from one of handle Connection Block 36 end, and handle Connection Block 36 has a groove 37 approaching the afterbody place, lining is equipped with turn 16 on it, holds a ball 14 in the ball hole 15 corresponding to turn 16 positions; One commutation board 22, in commutation board cavity volume 35, central tool one central shaft hole 23, the middle part is formed with a pair of commutation piece groove 24 that communicates with central shaft hole 23, and the bottom is installed with a square joint 25; A pair of commutation piece 30 is hubbed on a pair of commutation piece groove 24, and outer wall tool commutating tooth 29 matches with gear ring 2; One fluted disc 5 is arranged in fluted disc chamber 19, fixes with commutation board 22, and its upper recess has a knob chamber 12, and there is a central shaft hole 4 centre among the knob chamber 12, and the bottom part ring of this fluted disc 5 is provided with dish tooth 3; One commutation knob 9, in knob chamber 12, tool central shaft 10, central shaft 10 is inserted in the central shaft hole 23, and the corresponding both sides upper and lower of this central shaft 10 respectively is provided with a knock hole 8, respectively establishes spring 7, ejector pin 11 in the hole, and the top of a pair of ejector pin 11 contacts with the inwall of commutation piece 30 respectively; One handle 17 is inserted on the handle Connection Block 36, and tool ball grooves 18, gear 21, ball grooves 18 and ball 14 be scarf mutually, and gear 21 is nibbled with fluted disc 3 and joined.

A pair of commutation piece groove 24 described in the utility model respectively is a semi-circular groove, with it suitably a pair of commutation piece 24 of hub setting on it be shaped as fan-shaped.

The advantage of the utility model structure is can realize the quick lock of nut is unloaded.

Accompanying drawing and drawing explanation

Accompanying drawing is the three-dimensional assembling assumption diagram of the utility model.

The specific embodiment

Ask for an interview accompanying drawing, a pedestal 1 be a commutation board cavity volume 35 in the central, and the chamber wall of cavity volume is distributed with gear ring 2, and the top of gear ring 2 is formed with a smooth step, constitutes fluted disc chamber 19 by this step, and pedestal 1 outer wall is an one handle Connection Block 36.The ratch hole 13 of handle Connection Block 36 central authorities is passed through to described fluted disc chamber 19, be concaved with a groove 37 near handle Connection Block 36 afterbodys, be embedded turn 16 in this groove 37, the part that the cavity of groove 37 is provided with 15, one balls 14 of a ball hole then is located in this ball hole 15.When handle 17 aligning ratch holes 13 were inserted on the handle Connection Block 36, another part of ball 14 or title half sheet in addition then protruded in the ball grooves 18 across turn 16, by the location of this ball 14, handle 17 and handle Connection Block 36 are fixed.And as soon as ball 14 drops into ball grooves 18, the position of the gear 21 on the handle 17 of this moment also has been in the fluted disc chamber 19 just, and is meshed with dish tooth 3.Before being arranged to commutation board 22 in the commutation board cavity volume 35, pass a pair of pin hole 28 on the commutation board 22, the pin hole 31 at commutation piece 30 middle parts in regular turn with a pair of pivot pin 33 earlier, a pair of commutation piece 30 is pivoted on a pair of commutation piece groove 24 on the commutation board 22, and then commutation board 22 is inserted in the commutation board cavity volume 35, and add limit on the jump ring groove 27 that jump ring 26 snaps onto commutation board 22 belows solid.25 of square joints stretch outside commutation board cavity volume 35.After being placed in fluted disc 5 in the fluted disc chamber 19, solid by corresponding screw 20 on the fluted disc 5 and the screw hole on the commutation board 22 34 with commutation board 22 spiral shells with pair of screws 6.The button cover on commutation knob 9 tops is arranged in knob chamber 12 just, and its central shaft 10 is inserted in the central shaft hole 23 of commutation board 22 central authorities after then seeing through central shaft hole 4.After central shaft 10 inserted, a pair of ejector pin 11 on it contacted with the intrados 32 of a pair of commutation piece 30 respectively under the effect of spring 7.

The utility model is to embody it like this to lock removing nut apace because the utility model can be equipped with one group of end wherein and all can match with square joint 5, the other end then respectively with the adaptive transition sleeve of corresponding bolt and nut specification.Therefore, in the time will locking to a certain specifications of nuts, the transition sleeve of then selecting for use an end and nut specification to match, and it is nested with on the nut, again square joint 5 of the present utility model is stretched and placed this transition sleeve, at this moment, because of nut still is in the state that just revolves, the operator can be by the quick conrotatory handle 17 of the mode of turn screwdriver, because gear 21 is meshed with dish tooth 3, therefore, when handle 17 conrotatorys, make fluted disc 5 rotations, because fluted disc 5 fixes with commutation board 22, so commutation board 22 is also clockwise, square joint 5 is also right again, make transition sleeve also clockwise, finally make the nut that is enclosed on the transition sleeve screw in screw.When nut begins to enter locking state, owing to must increase, therefore, generally can not continue to use the quick turn mode of operation screwdriver again to the reinforcing of handle 17, operate and should change the mode of pulling into.At this moment, knob 9 revolved certain angle to clockwise direction as long as will commutate, make a pair of ejector pin 7 push up a corresponding end of the intrados 32 that reaches a pair of commutation piece 30 respectively, the commutating tooth 29 of a pair of commutation piece 30 outer walls is meshed with gear ring 2, this engagement is only worked handle 17 the operator when self side is pulled, therefore work as nut and enter locking state at the beginning, be operator when feeling that turn is painstaking, still can make nut enter into the solid state of sufficient spiral shell under the operation format apace using instead to pull.Unload when opening nut, knob 9 is stirred certain angle according to aforementioned rightabout as long as will commutate, and make a pair of ejector pin 7 change to the other end of the intrados 32 of a pair of commutation piece 30, and a nut is by loosening, then can resemble again and use the screwdriver to counterclockwise turn handle 17, make nut apace pine unload.
