Abstract
The utility model discloses a multi-purpose wrench, which is composed of a handle, a fixing plate and a movable plate. The movable plate is arranged on the fixing plate via a movable pin. A fastened working piece arranged between the fixing plat and the movable plate contacts the fixing plate with one point and the movable plate with two point to form a three-point stressing structure. The multi-purpose wrench can effectively transmit the torque of the wrench and ensure that the fastened working piece can be automatically clamped with rotating of the handle to make the looseness of the clamped working piece adjustable. An involute curve design for the facial line of the fixing plate makes the moving plate match sizes of the fastened working piece and clamp or loosen the fastened working pieces, thereby making easy and reasonable structure, convenience and high efficiency. A multi-purpose screwdriver spliced eye arranged at the other end of the handle enlarges the use of the multi-purpose wrench and increases functions, thereby bringing great convenience to users.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, particularly a kind of combination wrench.
Background technology
The at present conventional spanner that uses is applicable to the workpiece of parallel corner as adjustable wrench, and double offset ring spanner is applicable to the workpiece of five equilibrium corner, as hex nut etc.But after the angle of workpiece was damaged, spanner will be because of putting forth effort nowhere, skids and turning of work piece again; Though pipe vice can be used for the workpiece of circular appearance, utilize the frictional force turning of work piece, as water pipe etc.But its two face of pulling of pulling piece is parallel constructions, has only two folder points with workpiece, and the frictional force of symmetry folder point is limited, after the interface of workpiece gets rusty or kills, also can cause contact point to skid and can't turning of work piece.And aforesaid adjustable wrench and pipe vice need regulate the Flexible spanner piece by the rotation of leading screw and nut mechanism when clamping or unclamping workpiece, uses very inconvenient.It is comparatively narrow that they also exist application, deficiencies such as function singleness.
Summary of the invention
The purpose of this utility model is to provide a kind of for the deficiency that solves above-mentioned technology can loosen, tighten operation to the fastening workpiece of various geometric forms, and the combination wrench that can clamp automatically or unclamp fastening workpiece along with the rotation of handle.
In order to achieve the above object, a kind of combination wrench of the utility model design, comprise handle, fixedly pull piece and Flexible spanner piece, the Flexible spanner piece is combined in by the removable pin pin and fixedly pulls on the piece, by clamping in fixedly pull between piece and the Flexible spanner piece fastened workpiece with fixedly pull piece and a bit contact, contact with 2 of Flexible spanner pieces, constitute three contact force structures.
In order to guarantee that fastened workpiece can clamp automatically along with the rotation of handle, what just fastened workpiece was subjected in the rotation of handle makes a concerted effort, be to point in the opening of fixedly pulling piece and the formation of Flexible spanner piece, rather than outward thrust, in described formation three contact force structures, fixedly pull the diameter of the leg-of-mutton cylindrical that two contact lines that the opening part of piece and Flexible spanner piece contacted with fastened workpiece form less than this three contact.In order to guarantee that better the suffered direction of making a concerted effort of fastened workpiece points in the described opening, and make the Flexible spanner piece can adapt to the workpiece of different size with the gap of fixedly pulling piece formation in rotation process, the upper thread of pulling of fixedly pulling piece can be an involute curve.Be better clamping and rotate fastened workpiece, increase the frictional force of fixedly pulling between piece, Flexible spanner piece and fastened workpiece, can be provided with ratchet fixedly pulling pulling on the face of piece, Flexible spanner piece.For increasing the scope of application of the present utility model and function.The other end of handle also can be provided with the multi-purpose screwdriver spliced eye of replaceable attachment head.
The utility model combination wrench has increased the clamping point, can more effectively transmit the torsion of spanner, has guaranteed that fastened workpiece can clamp automatically along with the rotation of handle, make fastened workpiece to loosen, tighten rotation more free and relaxed; Fixedly pull piece and pull the involute curve design of upper thread, make the Flexible spanner piece can along with the rotation of handle from the size of fastened workpiece movingly and clamp or unclamp fastened workpiece, make more advantages of simple of structure, easy to use efficient; At the multi-purpose screwdriver spliced eye that the other end of handle is provided with, enlarged the scope of application of the utility model combination wrench, increased function of use, brought bigger convenience to the user.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment, but following embodiment does not limit content of the present utility model.
Embodiment 1:
As shown in Figure 1, a kind of combination wrench that present embodiment is described, it comprises handle 1, fixedly pulls piece 2, Flexible spanner piece 3, and Flexible spanner piece 3 is combined in by removable pin 4 pins and fixedly pulls on the piece 2, and fastened workpiece is fixedly being pulled between piece 2 and the Flexible spanner piece 3 by clamping during use.The upper thread 7 of pulling of fixedly pulling piece 2 is curves of gradually opening, make Flexible spanner piece 3 can clamp or unclamp fastened workpiece certainly movingly along with the rotation of handle 1, fastened workpiece contacts for any with the clamping point of fixedly pulling piece 2, is at 2 with the clamping point of Flexible spanner piece 3 and contacts, and constitutes three contact force structures.In described formation three contact force structures, fixedly pull the diameter of the cylindrical of the triangle ABC that two contact line AB that the opening part of piece 2 and Flexible spanner piece 3 contacted with fastened workpiece form less than this three contact, at this, the triangle ABC that three contacts form can first-selected equilateral triangle.
Be to increase the frictional force between spanner and the fastened workpiece, more effectively transmit the torsion of spanner, make turning of work piece lighter smooth and easy, be provided with ratchet 5 on the face fixedly pulling pulling of piece 2 and Flexible spanner piece 3.The other end of handle also is provided with the multifunctional screw driver spliced eye 6 of replaceable attachment head, replacing and use with convenient multi-functional screwdriver tool head, when using the multifunctional screw driver tool heads, the Flexible spanner piece 3 of handle 1 other end can be opened, to increase the moment of torsion, make the use of multifunctional screw driver tool heads more convenient laborsaving.
