Description
Technical field
The utility model relates to a kind of spanner, relates in particular to a kind of box spanner of controlled stroke.
Background technology
Box spanner is commonly referred to as sleeve: it is by a plurality of sleeves with hexagon ring or 12 jiaos of holes and be furnished with the multiple accessories such as handle, extension bar and form, be specially adapted to twist status very narrow and small or cave in very bolt or the nut of depths, box spanner generally all has the collet head of a set of all size and the handle of waving, extension bar, universal joint, revolve tool joint, elbow handle etc. is used for being inserted in hexagonal (hexagon)nut.The collet head of box spanner is a recessed hexagonal cylinder; Spanner is made by structural carbon steel or structural alloy steel conventionally, and Wrench head has the hardness of regulation, and centre and handle portion have elasticity.Yet common box spanner cannot be controlled accurately nut and be positioned at the position on bolt in nutting or bolt, when twisting bolt or nut at every turn, till being screwed to bolt or nut always and cannot rotating again, now be defaulted as and tightened, yet the nut of some specific position, it is very tight that the cooperation of bolt does not need the screw bolt and nut to twist, cooperation such as automobile hand brake screw bolt and nut, the cooperation of parking brake screw bolt and nut is too loose or too tightly all can affect the performance of parking brake, the formation of therefore each nut on bolt all needs to control accurately, thereby the sensitivity that keeps parking brake, and the stroke of the now common uncontrollable nut of box spanner on double-screw bolt, therefore incapability is applicable to the fastening of parking brake screw bolt and nut.
Chinese patent Granted publication number: CN202367648, on August 8 2012 Granted publication day, discloses a kind of box spanner, comprise wrenching bar, also comprise sleeve, sleeve one end is hexagonal end, the other end is round nose, and round nose has two teeth, has perforation circular hole on sleeve.This kind of box spanner diverse in function, has reduced the quantity of matching tool, and simple in structure, cost is low, easy to operate.Its weak point be this kind of box spanner in nutting or bolt, the stroke of uncontrollable nut on double-screw bolt, can not be applicable to the fastening of parking brake nuts and bolt.
Utility model content
The utility model is in order to overcome the box spanner of the prior art deficiency of the stroke of uncontrollable nut on double-screw bolt when in use, a kind of box spanner that can accurately control the controlled stroke of the position of nut on double-screw bolt is provided, has especially been applicable to the fastening of automobile hand brake nut and bolt.
To achieve these goals, the utility model adopts following technical scheme:
A kind of box spanner of controlled stroke, comprise wrenching bar and socket head, one end of described socket head is provided with hexagon ring, the other end of socket head is coaxially connected with wrenching bar, in described socket head, be provided with screwed hole, the axis of described screwed hole and the axis coaxle of hexagon ring, the side axial of described socket head is provided with the elongated slot connecting with screwed hole sidewall, in described screwed hole, be provided with positioning stud, in described elongated slot, be provided with slide block, the inner of described slide block and described positioning stud are rotationally connected.Before nutting, rotational positioning double-screw bolt, positioning stud band movable slider slides in elongated slot, adjusting nut stops operating after slide block slides into suitable position, then nut is put into the hexagon ring of socket head, the outer end of the outer end alignment stud of nut, rotating spanner handle, after in double-screw bolt stretches into screwed hole and during the end contact of positioning stud, wrenching bar stops operating, now nut has been screwed to suitable position accurately, this kind of box spanner can accurately be controlled the stroke of nut, be the accurately position of nut on double-screw bolt, especially be applicable to the fastening of automobile hand brake nuts and bolt.
As preferably, described positioning stud one end of close hexagon ring be provided with flat recess or cross recess.Can from hexagon ring, stretch in screwed hole with straight screwdriver or Phillips screwdriver, rotational positioning double-screw bolt, observe the position of slide block and determine the position of positioning stud in screwed hole, distance between slide block and one end of elongated slot can go to measure with slide measure, thereby guarantees the degree of accuracy of position.
As preferably, the outside of elongated slot is provided with origin reference location boss near one end of hexagon ring.First set the distance between two claws of slide measure, then a claw of slide measure is stuck in to origin reference location boss, rotate and regulate positioning stud, positioning stud moves along screwed hole, band movable slider slides along elongated slot, when slide block contacts with another claw of slide measure, represents that the position of positioning stud has been adjusted to the position of setting, then this kind of box spanner just can directly use, and whole adjustment process is very convenient.
As preferably, described socket head and wrenching bar are integral type structure.Wrenching bar passes to box spanner head moment of torsion while rotating, and integral structure intensity is large, and transmitting torque that can be stable is not easy to damage, processing, easily manufactured simultaneously, and cost is low.
As preferably, one side the elongated slot outside on socket head be provided with scale.When need to regulate the position of positioning stud, first according to estimating of elongated slot one side, carry out coarse adjustment, after the approximate location of positioning stud is regulated, re-use slide measure accurate adjustment, so just do not need to hold slide measure always and regulated positioning stud on a large scale on one side, regulate convenient, laborsaving.
As preferably, the tail end of described wrenching bar is provided with joint.Joint can directly be connected with the head of pistol electric drill, therefore can replace with the rotation of pistol electric drill turning of staff, and the fastening efficiency of nut is more increased, more laborsaving.
Therefore, the utlity model has the beneficial effect that can regulate accurately, control the stroke of nut on double-screw bolt, be especially suitable for the fastening of bolts and nuts on automobile hand brake.
