Abstract
The utility model relates to a compasses for drawing pictures in mechanical processing. The utility model has the essential point that a positioning ruler is connected to one drawing leg via a shaft, and a groove is arranged on the positioning ruler; a connecting shaft is installed on the other drawing leg, is connected with the positioning ruler and is positioned in the groove of the positioning ruler, and the upper end of the connecting shaft is provided with a fixing nut. A connecting spring or a spring sheet is arranged between the two drawing legs. The utility model has the advantages of convenient opening and closure and accurate and firm positioning.
Description
Technical field
The utility model relates to the divider calipers that uses in a kind of machining.
Background technology
Existing divider calipers is drawn leg by two and is formed, and its folding is mainly by artificial free folding, because divider calipers is firmly bigger in use, two distances of drawing between the leg is changed, thereby influence performance accuracy.And by the divider calipers of folding bolt, inconvenient operation.
Technology contents
The purpose of this utility model provides a kind of distances that can conveniently regulate between the two picture legs, and the divider calipers of firm position, to overcome the deficiencies in the prior art.Technical essential of the present utility model is: connect a positioning rule with axle on a picture leg, groove is arranged on the positioning rule, another is drawn a connecting axle is installed on the leg, connects positioning rule, and this connecting axle is positioned at the groove of positioning rule, and there is a hold-down nut its upper end.Between two picture legs, be equipped with and connect spring or shell fragment.The utlity model has folding with convenience, the firm advantage of accurate positioning.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Specific embodiment
1 is picture leg of the present utility model among the figure, two picture legs 1, picture legs 2 are connected on the fixture block 5 of upper end with axle respectively, fixture block 5 upper ends have rotating handle 6, its technical essential is: draw on the leg at two positioning rule 6 is installed, on the positioning rule 6 groove is arranged, draw on the leg 1 with axle connection positioning rule 6, draw a connecting axle is installed on the leg 2, this connecting axle is positioned at the groove of positioning rule 6, and there is a hold-down nut 3 its upper end, draws between the leg at two folding spring 4 is installed.During folding, draw leg 2 connecting axle in groove, move, when reaching the diameter that needs, fastening nut is pushed down positioning rule 6, thus with fixed diameter.
Claims (2)
1, a kind of divider calipers, picture leg (1), picture leg (2) by fixture block (5) and connection thereof are formed, it is characterized in that: draw between the leg at two positioning rule (6) is installed, positioning rule has groove on (6), draw on the leg 1 and be connected and fixed positioning rule (6) with axle, draw leg (2) and go up installation one connecting axle, this connecting axle is positioned at the groove of positioning rule (6), and there is a hold-down nut (3) its upper end.
2, a kind of divider calipers according to claim 1 is characterized in that: draw between the leg at two folding spring (4) is installed.
