Abstract

The utility model relates to a drawing tool, in particular to multi-functional compasses. A handle for quickly controlling the opening and closing of the compasses is respectively on the center square leg and the drawing leg, so as to accurately and quickly open or close the center square leg and the drawing leg, therefore, the use is very convenient and practical.

Description

Compasses

Technical field

The utility model relates to a kind of drawing tools, particularly a kind of compasses.

Background technology

As everyone knows, the compasses of which kind of model no matter, all comprise: rotary handle, one is fixedly connected with the connector of described handle, and is hinged on the Gauge for the centre of a circle pin on the described connector and draws pin.During use, Gauge for the centre of a circle pin and picture pin separate.Compasses on the market, when the user uses, all be with hand with the Gauge for the centre of a circle pin and draw pin and draw toward opposite direction respectively, just make Gauge for the centre of a circle pin and picture pin reach to separate and reach needed radius.This method often because both hands are firmly excessive, perhaps too small and do not reach user's demand radius, needs back and forth just can move needed radius to several times sometimes.

The utility model content

The purpose of this utility model is to solve the deficiencies in the prior art and the accurate quickly opening and closing Gauge for the centre of a circle of a kind of energy pin and the compasses of drawing pin is provided.

The purpose of this utility model is achieved by the following technical solution: a kind of compasses, comprise a rotary handle, one is fixedly connected with the connector of described handle, and be hinged on the Gauge for the centre of a circle pin on the described connector and draw pin, be fixed with an adjusting screw(rod) between Gauge for the centre of a circle pin and the picture pin, the Gauge for the centre of a circle foot is provided with folder pin leg, draw foot the lead for retractable pencil leg is set, folder pin leg and Gauge for the centre of a circle pin and lead for retractable pencil leg is characterized in that with to draw pin hinged: a lift that is used for controlling fast the compasses folding respectively is set on Gauge for the centre of a circle pin and picture pin.

Described lift, an end of lift is connected with adjusting screw(rod) by the pincers nail, and the other end links to each other with Gauge for the centre of a circle pin or picture pin by spring, and lift is provided with button hook with that face that Gauge for the centre of a circle pin or picture pin contact, and the lift another side is provided with one and refers to groove.

The beneficial effects of the utility model are: at the Gauge for the centre of a circle pin and draw a lift that is used for controlling fast the compasses folding respectively is set on the pin, accurately quickly opening and closing Gauge for the centre of a circle pin with draw pin, very convenient, practicality.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to Fig. 1, compasses of the present utility model, comprise a rotary handle 1, one is fixedly connected with the connector 2 of described handle 1, and is hinged on the Gauge for the centre of a circle pin 3 on the described connector 2 and draws pin 4, is fixed with an adjusting screw(rod) 5 between Gauge for the centre of a circle pin 3 and the picture pin 4, Gauge for the centre of a circle pin 3 ends are provided with folder pin leg 6, draw pin 4 ends lead for retractable pencil leg 7 is set, folder pin leg 6 and Gauge for the centre of a circle pin 3 and lead for retractable pencil leg 7 be with to draw pin 4 hinged, at Gauge for the centre of a circle pin 3 and draw a lift 8 that is used for controlling fast the compasses folding respectively is set on the pin 4.Referring to Fig. 2, the front end of lift 8 is connected with adjusting screw(rod) 5 by pincers nail 9, and with Gauge for the centre of a circle pin 3 or draw pin 4 and link to each other, lift 8 is provided with button hook 11 with that face that Gauge for the centre of a circle pin 3 or picture pin 4 contact to the other end by spring 10, and lift 8 another sides are provided with a finger groove 12.The button hook 11 of lift 8 buckled into Gauge for the centre of a circle pin 3 or draw in the groove 13 in the pin 4.During use, after pressing the finger groove 12 on the lift 8, spring 10 is toward pressing down, and the front end of lift 8 is toward upwarping, and drives pincers nail 9 outward the time, adjusting screw(rod) 5 is had an effect, Gauge for the centre of a circle pin 3 opens with picture pin 4, and hand leaves when referring to groove 12, and spring 10 recovers, the front end of lift 8 down moves, and drives pincers nail 9 simultaneously and gets back to original position.

The above only is the preferred embodiment of utility model, and not only above restriction utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included in the protection domain of the present utility model.
