Abstract
The utility model discloses a self-locking type multipurpose spanner which comprises a handle, a fixed jaw and a movable, wherein the fixed jaw and the handle are connected through a fixed piece, and the movable jaw is connected to the handle through a movable pin, and corresponds to the fixed jaw. The movable jaw is in an inwards bent hook shape, and the jaw surface of the fixed jaw is in a gradually opening curved shape. The fixed piece can be riveted by rivets, and can be also connected by screws. Ratchets are arranged on the jaw surface of the fixed jaw, and ratchets are arranged on the jaw surface of the movable jaw. In order to increase the strength of the movable jaw, the movable jaw can be a multi-layer structure. The self-locking multipurpose spanner breaks through the design philosophy of the traditional spanner, and solves various shortages and defects existing in the existing spanner, especially the detachable fixed connection of the fixed jaw and the handle and the pin connection of the movable jaw and the handle. The single change of each jaw after using wear or damage can be ensured, and the utility model has the advantages of large size application range, no slippage and good wrenching effect when used.
Description
Technical field
The utility model relates to a kind of manual hardware ﹠ tools, particularly a kind of self-locking 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 hexagon, as hex nut.But after being damaged of workpiece, spanner can be because of putting forth effort, skid turning of work piece more nowhere, though pipe vice can be used for circular appearance workpiece, but its two jaws are parallel construction, two folder point frictional force of symmetry are limited, after the workpiece interface gets rusty or kills, also can cause contact point to skid and can't turning of work piece, and above-mentioned instrument is when operation, need regulate moving jaw by the rotation of leading screw and nut mechanism, use comparatively inconvenience, therefore, they all exist function singleness, the comparatively narrow deficiency that waits of range of application.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology a kind of jaw replaceable, be suitable for specification limit wide, pull that Shi Buhui skids and a kind of self-locking combination wrench easy to use.
In order to achieve the above object, a kind of self-locking combination wrench that the utility model is designed, it comprises handle, regular jaw, moving jaw, connect by fixture between regular jaw and the handle, moving jaw is connected on the handle by removable pin and is corresponding with regular jaw, hook shape in moving jaw becomes, the actinal surface of regular jaw is open form curve-like gradually, a bit contacted with regular jaw by the fastened workpiece of clamping between regular jaw and moving jaw, contact with 2 of moving jaws, constitute three contact force structures.Described fixture can be closing-up, also can be that screw connects.Snap-in force when pulling in order to improve is provided with ratchet on the actinal surface of regular jaw, also can be provided with ratchet on the actinal surface of moving jaw.In order to make moving jaw obtain relative positioning, between moving jaw and handle, be provided with the movable locating device that constitutes by pellet shot from a slingshot, spring and locating hole.In order to improve the intensity of moving jaw, moving jaw can be a sandwich construction, and this sandwich construction can be two-layer, three layers, four layers or improve the number of plies according to the increase of moving jaw.Work to make things convenient for the user in order to increase self-locking combination wrench purposes, be provided with removable driver bit jack at the other end of handle.
The resulting a kind of self-locking combination wrench of the utility model, broken through the design concept of conventional spanner, the various defectives and the deficiency that exist in the existing spanner have been solved preferably, particularly shirk fixedly connected and the moving jaw between regular jaw and handle closes with pin between handle and is connected, guaranteed to change separately after each jaw uses wearing and tearing or damage, and the size scope of application is big during use, can not skid, pull effective.

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 self-locking combination wrench that present embodiment is described, it comprises handle 7, regular jaw 3, moving jaw 1, connect by fixture 4 between regular jaw 3 and the handle 7, moving jaw 1 is connected on the handle by removable pin 6 and is corresponding with regular jaw 3, hook shape in 1 one-tenth of the moving jaw, and the actinal surface of regular jaw 3 is open form curve-like gradually, but regular jaw 3 riveteds are fixed on the handle, use removable pin 5 moving jaw and handle pin altogether then.During use, when workpiece 2 is sandwiched in wherein, during turning handle, caught workpiece contacts with 2 of moving jaws, a bit contacts with regular jaw, constitutes three contact force structures.On the actinal surface of regular jaw 3, be provided with ratchet 8, on the actinal surface of moving jaw 1, be provided with ratchet 8, as shown in Figure 2, between moving jaw 1 and handle 7, be provided with by pellet shot from a slingshot 9, the movable locating device 5 that spring 10 and locating hole 11 constitute, movable locating device 5 can be located in the handle 7, on moving jaw 1 and inwall that handle 7 is connected, be provided with the garden that cooperates with pellet shot from a slingshot 9 recessed 13, when moving jaw 1 rotates, recessed 13 o'clock of the pellet shot from a slingshot 9 corresponding gardens that headed on by spring 10, moving jaw 1 and handle 7 are with regard to relative positioning, in addition, the other end at handle 7 can be provided with the driver bit jack 12 that can change.
In order to guarantee that fastened workpiece 2 clamps automatically along with the rotation of handle 7, making a concerted effort that just fastened workpiece 2 is subjected in handle 7 rotates is to point in the opening of regular jaw 3 and moving jaw 1 formation, rather than outward thrust, in 3 force structures of described formation, the leg-of-mutton outside diameter that the two contact lines that the opening part of regular jaw 3 and moving jaw 1 is contacted with fastened workpiece 2 form less than three contacts.Point in the described opening in order to guarantee fastened workpiece 2 suffered directions of making a concerted effort better, and the gap that moving jaw 1 is formed with regular jaw 3 in rotation process can adapt to the workpiece of different size, and ratchet 8 trends of regular jaw 3 can be involute curve shapes.In addition, influence its intensity owing to moving jaw 1 easily produces stress and slight crack in mechanical molding's process, moving jaw 1 can adopt two-layer, three layers or sandwich construction shown in Fig. 3, figure four.
