Abstract
The utility model discloses a self-resetting wrench, which comprises a handle (5); wherein, a notch (12) is arranged on a fixed clamp block (2) and fitted with the handle (5) and a driven clamp block (1); the fixed clamp block (2) is movably hinged with the handle (5) through a pin (4), and a reset spring (9) is arranged on the pin (4) between the fixed clamp block (2) and the handle (5); one end of the reset spring is fixed on the handle (5) and the other end is fixed on the fixed clamp clock (2), a handle circular tooth is arranged on the head part of the handle (5), a circular tooth (11) is arranged on the driven clamp block (1) and meshed with the handle circular tooth (3), two tooth grooves (7)are respectively arranged on the driven clamp block (1) and the fixed clamp block (2) and fitted with each other, and corresponding teeth (8) are respectively arranged on clamp jaws of the fixed clamp block (2) and the driven clamp block (1). By adopting the structure, the clamp jaw is able to automatically open and grip workpieces of different specifications by means of the force transferred from the handle, thus obviating the need of adjusting the size of the clamp mouth manually. The utility model has the advantages of reasonable structure, extremely convenient use, no slipping, high efficiency and long service life.
Description
One, technical field
The utility model relates to a kind of hand tools, and particularly a kind of jaw can strut and the automatically reset spanner that automatically resets automatically.
Two, background technology
The size that its jaw all needed alignment pieces to regulate jaw by craft when existing monkey wrench used, the place more can't accurately regulate at the dead angle, uses inconvenience more; Though and solid wrench does not need to regulate the size of jaw, can only be used for rotating the workpiece of same size; Particularly use more frequent building trade when building or dismantle scaffold, problem is more outstanding; Exist disadvantages such as operating rate is slow, efficient is low, jaw easily skids.
Three, summary of the invention
In order to overcome disadvantages such as existing spanner operating rate is slow, efficient is low, jaw easily skids, the utility model provides the spanner that automatically resets that a kind of jaw can be regulated and reset automatically, the workpiece of different size can both use.The technical scheme that its technical problem that solves the utility model adopts comprises handle, fixed clamp block is provided with the notch with handle and passive pincers piece, fixed clamp block is movably hinged by pin and handle, on the pin between fixed clamp block and the handle, be provided with back-moving spring, one end of back-moving spring is fixed on the handle, the other end is fixed on the fixed clamp block, head at handle is provided with the handle curved tooth, passive pincers piece is provided with the curved tooth that is meshed with the handle curved tooth, and passive pincers piece and fixed clamp block are provided with the teeth groove that cooperatively interacts; The jaw of fixed clamp block and passive pincers piece is provided with the teeth of mutual correspondence.After adopting said structure, to the workpiece of different size, jaw can both open automatically and holds workpiece tightly by the strength that handle transmits, and does not need the size of manual adjustment jaw; Have characteristics such as simple and reasonable, extremely easy to use, non-slip, that efficient is high, the life-span is long.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a drive mechanism schematic diagram of the present utility model.
Five, the specific embodiment
Illustrated in figures 1 and 2, the automatically reset specific embodiments of spanner of the utility model, it comprises handle 5, fixed clamp block 2 is provided with the notch 12 with handle 5 and passive pincers piece 1, fixed clamp block 2 is movably hinged by pin 4 and handle 5, on the pin 4 between fixed clamp block 2 and the handle 5, be provided with back-moving spring 9, one end of back-moving spring 9 is fixed on the handle 5, the other end is fixed on the fixed clamp block 2, head at handle 5 is provided with handle curved tooth 3, passive pincers piece 1 is provided with the curved tooth 11 that is meshed with handle curved tooth 3, and passive pincers piece 1 and fixed clamp block 2 are provided with the teeth groove 7 that cooperatively interacts; Workpiece skids in order to prevent to rotate, and the jaw of fixed clamp block 2 and passive pincers piece 1 is provided with the teeth 8 of mutual correspondence; For the ease of using and collecting, handle 5 is provided with taper knob 6, and taper knob 6 is provided with hanging hole 10.
Below use of the present utility model is further described, at first, operator grasps handle 5 is with the jaw alignment pieces, and handle 5 is slightly firmly toward counterclockwise advancing, the passive pincers piece 1 of spanner opens jaw automatically under the handle curved tooth on the handle 53 drives, vise workpiece; After vising workpiece, firmly rotate clockwise, passive pincers piece 7 is clamping work pieces under the handle curved tooth on the handle 53 drives, and firmly rotates and can tighten workpiece; After treating that workpiece is tightened, slightly firmly handle 5 is advanced toward counter clockwise direction, jaw opens automatically, can unload lower ejector lever, and under the effect of back-moving spring 9, fixed clamp block 2 drives passive pincers piece 1 and automatically resets to initial position.In like manner, firmly rotate counterclockwise, can unclamp workpiece.
