Description
Technical field
The utility model belongs to technical field of tools, is specifically related to a kind of Quick-adjusting wrench.
Background technology
Spanner is widely used in a lot of occasion, but the spanner employing of a lot of adjustable dimension is rotated by screw pair, and realize the adjustment of opening size, its governing speed is slow, is unfamiliar with the people of use, often starts also can adjust in the other direction.
Utility model content
The purpose of this utility model is to overcome the shortcoming existed in above-mentioned prior art, provides a kind of Quick-adjusting wrench, has governing speed fast, without the need to the advantage oppositely regulated.
For achieving the above object, the utility model by the following technical solutions: comprise the wrench body offering chute LL ', lower pincers, pressing plate, the first connecting plate and the second connecting plate;
The perpendicular setting of afterbody and its front end of described lower pincers, and afterbody is positioned at the chute in wrench body, and the end segment of lower pincers is provided with the groove that can match with the groove on pressing plate; And pressing plate is connected with wrench body with the second connecting plate through the first connecting plate respectively;
The second described connecting plate is provided with handle, and handle section and pressing plate are arranged at the both sides of wrench body respectively.
Spring is fixed with between the handle section of the second described connecting plate and wrench body.
Press section and first connecting plate of the second described connecting plate are parallel to each other, and jointly form parallelogram with pressing plate and wrench body.
Described pressing plate adopts bearing pin to be connected with between the first connecting plate and the second connecting plate;
The first described connecting plate and the second connecting plate are connected with all adopting bearing pin between wrench body.
When being in impaction state, the groove on the groove of the afterbody of described lower pincers and pressing plate fits tightly fixing, and spring is in impaction state.
The utility model has following beneficial effect: prior art of comparing, and the utility model is positioned at the lower pincers of the chute in wrench body by arranging afterbody, and the end segment of lower pincers is provided with the groove that can match with the groove on pressing plate; And pressing plate is connected with wrench body with the second connecting plate through the first connecting plate respectively; Second connecting plate is provided with handle, and handle section and pressing plate are arranged at the both sides of wrench body respectively.Thus when using spanner, after shifting correct position onto by movably descending pincers, pressing plate and lower pincers rear being compressed, utilizes the pressing plate of with groove to be fixed by lower pincers, carry out the mounting or dismounting be threaded.And then simple to operate, without the need to reverse adjustment, shorten regulating time, improve operating efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1-3, the utility model comprises the wrench body 2 offering chute LL ', lower pincers 3, pressing plate 4, the first connecting plate 5 and the second connecting plate 6; The perpendicular setting of afterbody and its front end of lower pincers 3, and afterbody is positioned at the chute LL ' in wrench body 2, and the end segment of lower pincers 3 is provided with the groove that can match with the groove on pressing plate 4; And pressing plate 4 is connected with wrench body 2 with the second connecting plate 6 through the first connecting plate 5 respectively; Second connecting plate 6 is provided with handle, and handle section and pressing plate are arranged at the both sides of wrench body 2 respectively, is fixed with spring 7 between the handle section of the second connecting plate 6 and wrench body 2; First connecting plate 5 and the second connecting plate 6 be arranged in parallel; Pressing plate 4 adopts bearing pin to be connected with between the first connecting plate 5 and the second connecting plate 6; First connecting plate 5 and the second connecting plate 6 are connected with all adopting bearing pin between wrench body.Press section and first connecting plate 5 of the second connecting plate 6 are parallel to each other, and jointly form parallelogram with pressing plate 4 and wrench body 2.When being in impaction state, the groove on the groove of the afterbody of lower pincers 3 and pressing plate 4 fits tightly fixing, and spring 7 is in impaction state.
Using method: in order to treat that mounting or dismounting screw head 1 clamps rotation, first a side of screw head 1 is adjacent to the lower surface of the upper jaw of wrench body 2, now because the elastic force on spring 7 can by four-bar linkage ABCD by pressing plate 4 jack-up, as shown in Figure 1,3 are clamped with under hand propelled, make the groove LL ' interior upward sliding of the part of lower pincers rear belt groove in wrench body 2, and hold out against the side of screw head 1.Now, move point articulated on the second connecting plate 6 of wrench body 2 at A with bearing pin with another hand, in two connecting plates, only have that root of right side in fig. 2 to have by the handle portion of spring jack-up.Second connecting plate 6 rotates around A point relative to wrench body 2.Due to by bearing pin at A, B, C and D place is respectively by wrench body 2, second connecting plate 6, pressing plate 4 and connecting plate 15 as shown in Figure 2 hinged between two, and form parallel-crank mechanism ABCD, so driven pressing plate 4 can do the plane motion being parallel to wrench body 2 right flank all the time, groove on pressing plate 4 can compress with the ditch slot fit at lower pincers 3 rear portion, prevent lower pincers 3 from gliding, keep stepping up screw head 1 together with the upper pincers of wrench body 2, by rotating spanner main body 2, realize the dismounting be threaded, as long as the hand grasping wrench body 2 and the second connecting plate 6 does not loosen, the distance of the bayonet socket up and down of spanner can remain constant, until complete the dismounting be threaded.
When completing after dismounting is threaded, the hand semi-coast of wrench body of holding with a firm grip 2, second connecting plate 6 is by spring 7 jack-up, by the quadrangular mechanism ABCD be connected to form between above mentioned component, pressing plate 4 lifts from lower pincers 3, lower pincers 3 along the interior slide downward of groove LL ' in wrench body 1, and can be taken away from screw head 1.
