Description
The utility model is to belong to a kind of manual assembling, dismounting adjustment means.
Existing adjustable wrench and cutting pliers are plant equipment and family two kinds of instruments commonly used, because both functions are inequality, in use the two can not replace, and just feels numerous and diverse inconvenience in the work high above the ground and the work of going out.Adjustable wrench needs as requested when work, constantly regulates the size of pulling mouth, and especially to new machinery, careless manipulation can damage nut in the work, and the amount of labour of regulating is heavy, influences efficiency.In the cutting pliers work, subtended angle is little, and the excessive component that skids off is bigger than normal, can't clip object sometimes, and the disconnected object of pincers is relatively required great effort, and does not satisfy people's needs.
The purpose of this utility model is to make a kind of multifunctional wrench, and the function of existing adjustable wrench and cutting pliers is concentrated on the one, can regulate the size of pulling mouthful automatically, and convenient and strength-saving clamping or the card object that breaks is easy to carry.
The utility model mainly by fixedly pull body 1, Flexible spanner body 2, pawl 3, paw spring 4, spring driving lever 5, advance spring 6, regulate spring 7, driving lever 8, running roller 9, swing cover 10, return spring 11, limit shaft 12, movable trigger piece 13 form, as shown in Figure 1; It is characterized in that:
A, Flexible spanner body 2 insert and fixedly pull in the body 1 front end cavity, and connect with the other end that is fixed on the spring driving lever 5 of fixedly pulling body 1 inner chamber, driving lever 8 one ends with fixedly pull intracoelomic cavity and connect, connect in the middle of the other end and the spring driving lever 5, running roller 9 is connected in fixedly to be pulled in body 1 center lumen;
B, pawling 3 is connected in movable trigger piece 13 leading sections, and joins with Flexible spanner body 2 end faces saw shape tooth, and paw spring 4 is fixed on movable trigger piece 13 front end sides, and is crimped on and pawls on 3;
C, return spring 11, swing cover 10 be supporting to be positioned at movable trigger piece 13 anterior elongated slots, and movable trigger piece 13 places and fixedly pulls body 1 anterior inner chamber, and joins with the riveting in limit shaft 12, the swing cover 10; Advance spring 6 one ends to connect with driving lever 8, the other end is fixed on the movable trigger piece 13 with regulating spring 7, and there is the inclined-plane a of convex at movable trigger piece 13 middle parts, and are corresponding with running roller 9, form multifunctional wrench.
The course of work of the present utility model:
When need switching nut or gripping objects, earlier the openend of spanner is shifted to gripped object, pull movable trigger piece 13 again, make propelling spring 6 fixed thereon press to driving lever 8 and make its swing, also drive simultaneously 5 swings of spring driving lever, Flexible spanner body 2 along parallel mobile in the cavity of fixedly pulling body 1, will be clamped in and fixedly pull the object that body 1 and Flexible spanner body 2 pull between the mouth and clamp.Advancing spring 6 is that swing with movable trigger piece 13 advances, because driving lever 8 one ends are connected in and fixedly pull on the body 1, the other end connects with spring driving lever 5 middle parts; Advance spring 6 and 8 middle connections of driving lever, under same pivot angle, radius is long more, and the arc of its swing is just big more; So advance spring 6 and driving lever 8 interface places swing arc length just to be less than driving lever 8 and spring driving lever 5 interface places swing arc length, driving lever 8 has amplification.So just can reduce the activity of movable trigger piece 13.When movable trigger piece 13 is swung, make it be connected in 3 swings thereupon of pawling of end, make it to embed gradually at the bottom of the saw shape tooth of Flexible spanner body 2 end faces.Pawling 3 just produces the layback swing after automatically at the bottom of the contact saw shape teeth, and advances Flexible spanner body 2.3 do not throw off at the volley for guaranteeing to pawl, pawl 3, guarantee to pawl and 3 do not throw off with paw spring 4.Swing along with movable trigger piece 13, in order to increase journey, there is inclined-plane a at the convex place at the middle part of movable trigger piece 13, when this inclined-plane a with fixedly pull running roller 9 on the body 1 and join after, along with swing, movable trigger piece 13 produces make progress mobile simultaneously, promptly compress the return spring 11 in its preceding end slot, and the groove of swing axle sleeve 10 and movable trigger piece 13 has the space, thereby forcing to pawl 3 promotes Flexible spanner body 2 with very big thrust and press and be stuck on the object, thus chucking or cut off object.In the time will decontroling object or quit work, unclamp movable trigger piece 13, under the reaction of spring driving lever 5, propelling spring 6 and return spring 11, can automatically reset.In order to prevent movable trigger piece 13 free activities, finish with limit shaft 12.Regulate spring 7 main adjustings and advance spring to have bigger flexural deformation ability to bear, enough operating pressures are arranged again.
The utility model is compared with prior art: this spanner free state is to pull mouth to be in the maximum open size; Only need hand movable trigger piece 13 and the shank of fixedly pulling body 1 during use, inwardly button is pulled, Flexible spanner body 2 is understood fast automatic sliding into and gripping objects, and then forced feed, to object compress or cut off, operation such as switching, bending, after finishing, as long as relieving activity trigger piece 13, Flexible spanner body 2 can be retired automatically and reset.This spanner is compared with existing adjustable wrench simultaneously, under any condition, all need not regulate and pull a mouthful size, no matter the gripping objects size is not less than object size as long as this spanner is pulled mouth, all can implement operation.At work, adjusting prevents to damage object automatically.Compare with cutting pliers: under the suitable situation of specification, this wrench opening size is bigger, and it is bigger to adapt to working range.The opening part of this spanner all is in parastate when static and dynamic, stronger stability is arranged during clamping, prevents that the big object that occurs of subtended angle from skidding off the component phenomenon that can't clip that causes bigger than normal.Its function is complete, carries, easy to operate.
