Description

Multi-functional divider calipers

Technical field

The present invention relates to a kind of drawing instrument, especially a kind of multi-functional divider calipers.

Background technology

At present, that generally sells on the market is compasses or also has ellipsograph, and often the structure of ellipsograph is comparatively complicated; And these compasses, ellipsograph function singleness; Can only correspondence draw circular or ellipse, can not draw multiple complex figure, especially special-shaped figure.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structurely, can draw the multi-functional divider calipers of different shape figure.

Be to realize above-mentioned purpose, the present invention adopts following technical scheme: a kind of multi-functional divider calipers comprises that moving foot lever and bottom that the bottom is provided with paintbrush or pen core connector are provided with the foot lever of deciding of deciding pin; Decide foot lever middle part and be vertically installed with gauge finder, gauge finder with decide foot lever and removably connect, be provided with above the gauge finder and be set in the movable sleeve of deciding on the foot lever; Movable sleeve connects a U-shaped piece through elastic device, and the edge of gauge finder is inserted in the U-lag of U-shaped piece, is provided with the pin of mouth of connecting trough in the U-lag; Be equipped with fastening bolt on the U-shaped piece; The bottom of fastening bolt penetrates in the U-lag and over against gauge finder, the setting of staggering of fastening bolt and pin, and moving foot lever is divided into epimere, stage casing and hypomere from top to bottom; The downside of said U-shaped piece is fixedly connected with the epimere of moving foot lever; The epimere of moving foot lever is with the stage casing is hinged, stage casing and hypomere are hinged, and the pin joint place of epimere and stage casing, stage casing and hypomere is equipped with fastening positioning device, and the connector of said connection paintbrush or pen core is arranged at the bottom of moving the foot lever hypomere.

The middle part of deciding foot lever is laid with convexity along circumferential interval; Protruding surface, outer ring is circular arc; All protruding surfaces, outer ring are with circumference and be provided with external screw thread; Gauge finder medium position correspondence decides foot lever and all convexities are provided with jack, and gauge finder is pegged graft through jack with deciding foot lever, and the below of gauge finder is provided with the gauge finder clamp nut with protruding external screw thread assembling.

Said gauge finder is shaped as the closed figure of rectilinear polygon or curve polygon or linear and curve composition.

Said gauge finder is complete to be provided with a plurality ofly, and the shape of each gauge finder is different with other gauge finders.

Decide foot lever and be provided with block, said gauge finder shelves are at the block downside, and said movable sleeve is positioned at the upside of block, the top of the deciding foot lever divider calipers head that has been threaded.

The bottom of said moving foot lever epimere is the bias type that extends obliquely laterally from the inboard; The bottom of moving foot lever epimere is provided with opening epimere link slot outwardly; And it is interior and hinged through pin one with moving foot lever epimere bottom that the upper end connector in moving foot lever stage casing inserts the epimere link slot, and the end of pin one is equipped with clamp nut; The bottom in said moving foot lever stage casing is the oblique laterally bias type that extends below from the inboard; The bottom in moving foot lever stage casing is provided with opening stage casing link slot inwardly; And it is interior and hinged through pin two with bottom, moving foot lever stage casing that the upper end connector of moving foot lever hypomere is provided with insertion stage casing link slot; The end of pin two also is equipped with clamp nut, and clamp nut is said fastening positioning device.

Said elastic device comprises that two ends all connect the spring of spring connector; Spring connector and movable sleeve are hinged; Another spring connector and U-shaped piece are hinged; Said two spring connectors and spring all are sleeved in the pogo barrel, and the pogo barrel two ends all are no more than two pin joints of two spring connectors.

Beneficial effect of the present invention is:

1. when the U-shaped piece rotated around the gauge finder edge, the paintbrush or the pen core that drive moving foot lever and moving foot lever bottom were drawn, and the figure of drawing out is identical with the gauge finder shape.

2. moving foot lever is divided into three sections, adjacent two sections hinged, the graphics shape of then drawing out is identical with gauge finder, and scalable its size.

3. gauge finder can be geometric figure commonly used or other any enclosed curve shape or polygons such as ellipse; Or abnormity, promptly gauge finder can be an arbitrary shape, so multi-functional divider calipers of the present invention can be drawn the arbitrary shape identical with gauge finder; And gauge finder can be according to daily need; Completely be arranged to difform a plurality ofly, be set in and decide on the foot lever, easy to use.

4. when the graphic outer contour of gauge finder had the angle point of indent, during slip, the pin in the U-shaped piece offseted with being somebody's turn to do interior angle point, avoids the U-shaped piece to draw inaccurate defective for the indent angle point.

5. be screwed into when offseting with gauge finder when fastening bolt, U-shaped piece and gauge finder are fixed together, and rotate the divider calipers head, and U-shaped piece and gauge finder together rotate, and moving foot lever is with the rotation of U-shaped piece, the circle of can drawing like this.
