Description
Technical field
The utility model relates to a kind of simple and easy compasses.
Background technology
Compasses are the instruments of draw circles or string in mathematics and drawing, are usually used in construction with ruler and compasses, in the manufacture process of handicraft, need make round, conventional compasses to iron plate and can't finish this work, because pencil can't demonstrate circular profile clearly on iron plate.
The utility model content
But being to provide on a kind of iron plate, the purpose of this utility model does circle, and simple in structure, make also simple and easy compasses easily.
The technical solution of the utility model is: a kind of simple and easy compasses is characterized in that: comprise a stock, described stock one end bottom is provided with first syringe needle; Be arranged with the sleeve pipe of slippage on stock on the described stock, described sleeve pipe bottom is welded with second syringe needle.
Among the utility model embodiment, described sleeve pipe top is provided with first clamping screw that matches with stock, so that sleeve pipe is fixed on the stock.
Among the utility model embodiment, described stock one end bottom is provided with sleeve, and described first syringe needle is plugged in the sleeve, and described sleeve side is provided with second clamping screw so that first syringe needle is fixed in the sleeve.
Advantage of the present utility model is: do circle on the iron plate, and also simple in structure, it is also convenient to make, and easy to assembly, the material that uses is made as the waste material that produces in the handicraft manufacture process, has saved cost, also makes the data reasonable use simultaneously.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
