Description

multipurpose drawing ruler

The utility model relates to a multi-purpose drawing ruler in the field of drawing utensils, in particular to a multipurpose drawing ruler which is provided with a retractable cutter and a set of matching seats to further increase the multi-functionality of the drawing ruler. Use drawing ruler.

The general stationery ruler has evolved from the single purpose of the long ruler to a parallel ruler that can be moved in parallel, such as Taiwan Application No. 77204638, No. 78209476 and No. 80212023. Parallel lines can be drawn on the desktop, and there is also a center positioning button on the ruler surface, which has the functions of pressing the center positioning button as the center of the circle, and drawing a circle according to the radius of the small hole on the ruler surface, so it can provide The user increases its convenience when drawing; however, although the existing parallel ruler can give full play to the versatility of the ruler tool as much as possible, it ignores the problem when the drawn graphics must be cut, especially in the In courses such as art and labor, it is necessary to cut and draw graphics with knives, so that students and teachers who instruct students suffer greatly when instructing students to perform labor operations; therefore, it can be seen that the existing parallel ruler can only provide the function of drawing , when wanting to be used for relying on cutting paper, then must be cut and just can be finished by other cutters, and this is its one major shortcoming. Therefore, although existing parallel rulers have multiple functions for drawing, they cannot take into account the necessary cutting and leaning functions of the ruler tool, thus greatly losing the beauty of the original design of such parallel rulers, which is a pity.

The purpose of this utility model is to overcome and improve the shortcomings of the above-mentioned existing parallel rulers, and provide a multi-purpose drawing ruler with a new structure, so that an adjustable and telescopic cutter and a group of matching seats are added on the parallel rulers, and the use of The cutting knife can cut a continuously extended straight line when the parallel ruler is moved, and can cut a circle with the center positioning button as the center of the circle. In addition, there is an assembly seat on one side of the ruler body, which can be attached to fix the magnifying gauge, so that it can increase its efficacy.

The purpose of this utility model is achieved by the following technical solutions.

A multi-purpose drawing ruler, including a parallel ruler, is characterized in that it comprises:

A parallel ruler, a chute is provided above the roller cover, a short screw rod protruding upward is provided in the middle of the chute, and an internal thread fixing seat is fixed on one side of the ruler surface;

A telescopic cutter, its main body is a telescopic rod, the telescopic rod can just be arranged in the chute, the telescopic rod is also provided with a guide groove for the short screw to pass through the guide groove, and a knob is used on the guide groove Adjust the tightness of the telescopic rod. In addition, a vertically folded hollow sleeve is provided on one side of the telescopic rod. A long groove is provided on one side of the sleeve, and a push rod and a push rod connected to each other are arranged in the sleeve. folding rod;

A set of supporting seats is a rotating shaft pierced in a sleeve, and a part of the rotating shaft can protrude from the perforation on the sleeve, and the outer side of the sleeve is provided with threads, which can be screwed into the internal thread fixing seat ;

Continuous straight lines and circles can be cut arbitrarily by the retractable and adjustable cutting knife on the parallel ruler.

The purpose of this utility model can also be further realized by the following technical measures.

In the aforementioned multi-purpose drawing ruler, the push rod in the casing is provided with a short screw corresponding to the side of the long groove, and is screwed to the outside of the long groove by a knob.

The aforementioned multi-purpose drawing ruler, wherein the folding rod is connected to the front of the push rod with a bolt, and a blade holder is provided on the front edge of the folding rod, and a blade is fastened by a set of knobs and a tightening bolt in the blade holder. Clamped into the insert seat.

Compared with the prior art, the utility model has obvious advantages and positive effects. As can be seen from the above technical solutions, the design of the present utility model has the following advantages:

(1) Using the structural design of the cutting knife, it can cut continuous straight lines and drawings with the translational movement of the parallel ruler and the center positioning button.

(2) The storage design of the casing can make the push rod and the folding rod fully retracted therein when not in use at ordinary times, which can provide the safety of storing the blade.

(3) There is an assembly seat fixed on one side on the surface of the parallel ruler, which can provide other utensils to be used together with the parallel ruler, which further increases the convenience of its use.

To sum up, the multi-purpose drawing ruler of the present utility model can mainly be used to improve and overcome the existing parallel ruler which can only provide the function of drawing. When it is intended to be used for cutting paper, it must be cut with other cutters to complete it. The shortcoming is that it is mainly provided with a retractable and adjustable cutting knife on the body of the general parallel ruler. The blade seat part of the cutter can be retracted and concealed in the casing when it is not in normal use; At this time, the protruding cutter can cut synchronously with the movement of the parallel ruler, and use the center positioning button on the ruler body as the center of the circle, and can cut out circular lines while rotating the ruler body. There is an assembly seat on the side; by the combination of the above structures, the utility model can not only have the function of general drawing on the parallel ruler, but also provide the functions of cutting and scaling, thereby greatly improving the drawing ruler. multi-purpose usability and convenience. The utility model can indeed achieve the expected purpose and effect, and provides a multi-purpose drawing ruler structure that is very convenient for straight line and circular cutting, and its design is also the first that has never appeared in similar products. The use effect of the parallel ruler is really helpful, thereby being more suitable for practicality, and it is actually a new design with novelty, creativity and practicability.
