The angle of section left part and bottom side is 60 °, and sliding mechanism is both provided between adjacent linkage section, and the sliding mechanism includes setting
Set a linkage section one end sliding rail and the sliding slot in adjacent another linkage section end is set, the sliding rail is mutually stung with sliding slot
It closes, stroke groove along its length is provided in the middle part of the sliding rail, the both ends of the stroke groove are both provided with aperture and are more than slot
Wide circular hole, described sliding slot one end are provided with screw, which is pierced by sliding slot upper side wall, the underface of sliding slot face screw
Lower wall on be provided with the threaded hole to match with screw, the screw slides in stroke groove, setting in the middle part of the screw
There is outer diameter to be less than the annular protrusion of bore inner diameter, the groove for accommodating protrusion is provided on the sliding slot upper side wall, so that on screw
When rising, protrusion is located in groove, and screw lower part is located in stroke groove.
Further, the screw head is provided with torsion circle.
Further, the sliding slot and sliding rail are oat tail groove structure.
Compared with prior art, the utility model has the advantages that：The present apparatus can draw straight line and draw 30 °,
45 ° and 60 ° of angles, it is simple in structure, it is easy to use.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Specific implementation mode
Embodiment one：As shown in Fig. 1 ~ 4, a kind of ruler for painting special angle, including upper side wall are provided with the of graduated scale
One linkage section 1, the second linkage section 2, third linkage section 3 and the 4th linkage section 4, it is rectangular that four linkage sections collectively form a strip
The angle of body, the first linkage section right part, the second linkage section left part and bottom side is 30 °, the second linkage section right part, third
The angle of linkage section left part and bottom side is 45 °, third linkage section right part, the 4th linkage section left part and bottom side angle
It is 60 °, sliding mechanism is both provided between adjacent linkage section, the sliding mechanism includes being arranged in a linkage section one end
Sliding rail 5 and the sliding slot in adjacent another linkage section end is set, the sliding rail is mutually engaged with sliding slot, and the sliding rail middle part is provided with
The both ends of stroke groove 51 along its length, the stroke groove are both provided with the circular hole 52 that aperture is more than groove width, the sliding slot
One end is provided with screw 8, which is pierced by sliding slot upper side wall, is provided in the lower wall of the underface of sliding slot face screw
The threaded hole 6 to match with screw, the screw slide in stroke groove, and outer diameter is provided in the middle part of the screw less than in circular hole
The annular protrusion 81 of diameter is provided with the groove 7 for accommodating protrusion on the sliding slot upper side wall, and when so that screw rising, protrusion is located at
In groove, screw lower part is located in stroke groove.
In the present embodiment, the screw head is provided with torsion circle 82, convenient for twisting screw.
In the present embodiment, the sliding slot is oat tail groove structure with sliding rail, and occlusion is more firm.
In the present embodiment, screw is layer adjacent at the position of graduation mark, and four link blocks constitute a ruler, at this point, spiral shell
Nail convex block sinks to stroke groove and closes in the circular hole of scale line side, and screw is simultaneously screwed onto in the threaded hole of bottom；Which angle needed
When, the screw at this is turned on, screw convex block is detached from circular hole and enters in groove, mobile another piece of linkage section, and screw bottom exists at this time
Sliding in stroke groove, when being moved to end, screw protrusion is sunk in the circular hole of non-scale line side, tightens screw, two link blocks
It is fixed, picture angle can be carried out.
When making, screw can be installed into without torsion circle in sliding slot, then welding torsion circle, sliding rail one end circular hole is cut
Half is got off, screw enter after, then by this part bonding or welding.
