Abstract
A multi-purpose scribing compass is composed of main central axle, fixed needle, movable axle, pen fixing hole, pen, plate template, fixing screw, rotary block, fixing screw bolt, jam rod, tension spring, telescopic axle and screw bolt. Its advantages are wide size range and high precision.
Description
Technical field: the present invention relates to a kind of planing.
Background technology: I disclose a kind of planing in Chinese patent 02200369.X, advantage is to draw ellipse or triangle, multiple figure such as polygonal, problem is because movable axis is fixed on the spill spin block by little axle, and the size and the accuracy of the figure of drawing are restricted.
Summary of the invention: it is bigger to the objective of the invention is to design a kind of size variation scope than figure that above-mentioned patented product is drawn, the multifunctional compass that accuracy is higher.
Above-mentioned purpose can be realized by following proposal: it comprises main central shaft 1, and locking pin 12 is equipped with in main central shaft lower end, also comprises movable axis 3 etc.; Template die 11 usefulness hold-down nuts 9 are fixed on the middle part of main central shaft, spill spin block 2 is sleeved on main central shaft top, can rotate, establish set bolt 4 at the movable axis middle part, bar 8 is installed on the set bolt, one end of kelly is against on the edge of template die, and extension spring 10 also is housed on the movable axis, and the other end of extension spring is fixed on the main central shaft, telescopic shaft 6 is sleeved on the movable axis bottom, on can be in movable axis, under be free to slide, there is a fixing hole 7 the telescopic shaft lower end, pen 13 is contained in the fixing hole, side at the telescopic shaft middle part is established opening longitudinally, establishes bolt 5 in the movable axis lower end, and the bolt front end inserts opening, make on the telescopic shaft energy, under be free to slide and can not drop out, we establish slideway 14 on spill spin block 2, movable axis 3 is fixed on the slideway by set screw 15, can be fixed on any place of slideway as required.
Advantage of the present invention is: ellipse of drawing with the 02200369.X patented product or triangle, various figures such as polygonal are compared, and the size variation scope of the various figures that the present invention drew is bigger, and accuracy is also higher.
Description of drawings: Fig. 1 is an overall schematic of the present invention;
Fig. 2 is the schematic top plan view of oval template die.
The specific embodiment: at main central shaft lower end dress locking pin 12, locking pin is made up of three pins of tip distribution triangular in shape, template die 11 usefulness hold-down nuts 9 are fixed on the middle part of main central shaft, spill spin block 2 is sleeved on main central shaft top, can rotate, establish slideway 14 on the spill spin block, movable axis 3 is fixed on the slideway by set screw 15, establishes set bolt 4 at the movable axis middle part, and bar 8 is installed on the set bolt, one end of kelly is against on the edge of template die, extension spring 10 also is housed on the movable axis, extension spring in addition-end is fixed on the main central shaft, telescopic shaft 6 is sleeved on the movable axis bottom, on can be in movable axis, under be free to slide, one side is established opening longitudinally at the telescopic shaft middle part, and bolt 5 is established in the movable axis lower end, and the bolt front end inserts opening, a fixing hole 7 is established in the telescopic shaft lower end, and pen 13 is equipped with in the fixing hole.Make ellipse, triangle in addition as required, multiple standards template die such as polygonal is standby.
