Abstract
The utility model discloses a one-way spanner which is a machine tool. When the one-way spanner is used, a cap nut can be screwed to rotate towards one direction only by oscillating the handle of the spanner to-and-fro. The one-way spanner comprises a spanner body, a slide block, and a tension spring; the head of the spanner body is provided with a slideway in which the slide block is inlaid and slid; the tension spring is arranged between the slide block and the spanner body; the slide block is provided with an inclined plane on which the edge of the cap nut is toggled when the one-way spanner rotates contrarily. The utility model has the characteristics of simple structure, and easy use.
Description
The utility model relates to machine tool, is a kind of lug wrench.
At present, in the mechanical industry, a kind of lug wrench that adopts ratchet mechanism is arranged, lug wrench in use, the handle of the spanner that only need swing back and forth just can turn nut and rotate towards a direction.
The purpose of this utility model is to provide another kind of lug wrench simple in structure.
The purpose of this utility model is to realize like this, lug wrench is made of wrench body, slide block and extension spring, the head of wrench body is provided with the chute that embeds and slide for slide block, extension spring is arranged between slide block and the wrench body, and slide block is provided with the inclined-plane of stirring for the nut seamed edge when lug wrench reverses.
Lug wrench is action like this.At ordinary times, slide block is drawn by extension spring and is parked in the chute bottom.When lug wrench was clockwise, slide block was exactly a side of jaw of spanner, promoted the rotation of workpiece nut; When counter-rotating, frictional force keeps workpiece motionless, and the spanner backward rotation so the seamed edge of workpiece nut is stirred the slide block inclined-plane and made slide block leave original position, is left the slide block inclined-plane until this seamed edge, and slide block just resets under the extension spring effect.Lug wrench is when counter-rotating, and the workpiece nut does not rotate, the realization that comes to this.
Characteristics of the present utility model are: simple in structure, easy to use.
Further narrate below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model lug wrench.Slide block (2) is embedded in the chute in jaw left side of wrench body (1), and extension spring (3) is between slide block and wrench body, and slide block is provided with inclined-plane (4).
Fig. 2, Fig. 3 are the action schematic diagram of the utility model lug wrench.Dotted line is the nut position of workpiece among the figure, and arrow is represented the rotation direction of lug wrench.Fig. 2 is lug wrench when clockwise, and the slide position is in the chute bottom, and slide block promotes the nut of workpiece.When Fig. 3 reversed for lug wrench, slide block is stirred the slide block inclined-plane by the seamed edge of workpiece nut made slide block leave original position.
Embodiment:, be the fixing lug wrench of a kind of jaw size referring to Fig. 1.Wrench body and slide block system make through machining with tool steel material, and extension spring system makes with spring steel.If lug wrench structure of the present utility model is done on the monkey wrench that jaw size can change, just for having the lug wrench of moving jaw.
