Abstract
The invention provides a compass. An automatic pencil is additionally arranged on a support leg, and a pencil tip and a needle tip are of automatic structures, and can be freely extended and retracted by pressing a press button at the top part of the support leg. In the use process, the needle tip is used for positioning, and a pencil head is rotated to draw a circle.
Description
Technical field
The present invention relates to a kind of according to button press cap income, the Automatic compasses of releasing nib and needle point.
Background technology
At present, known compasses are made up of nib, rotating shaft, button cap, two supporting legs, nib, needle points etc.With needle point location, adjust two leg distances according to the size of drawn circle, hold written rotation direction.Draw circle very convenient, but for compasses preservation storage and take out use there is certain danger.Had much by the case of pricking the hand.
Summary of the invention
In order to overcome the indispensability of the existing use of existing compasses, the sharp-pointed of needle point damages the meeting of user again, the invention provides a kind of novel bow compass utensil, not only can not affect the use value of compasses, can also reduce personal injury.
The technical solution adopted for the present invention to solve the technical problems is: other design does not change.The needle point of compasses and nib are changed respectively into the Design Mode of propelling pencil, make it stretch and to receive needle point and nib by the button cap pressing compasses supporting leg top.
The invention has the beneficial effects as follows: facilitate nib to regulate at picture bowlder, regain needle point when not using and put into receiver, accidental injury can not be touched in unwitting situation.Simplicity of design, more convenient operation.
accompanying drawing explanationbelow in conjunction with accompanying drawing and case study on implementation, the present invention is further described
Figure is front view of the present invention
(1) nib, (2) rotating shaft, (3) nib button cap, (4) needle point button cap, (5) nib supporting leg, (6) needle point supporting leg, (7) nib, (8) needle point in figure.
Specific embodiments
nib (1) and rotating shaft (2) are linked together, two compass legs (5) (6) are designed to cylinder, middle connect button cap (3) (4) and nib below (7) and needle point (8) by the technology of mechanical pencil, realized the folding and unfolding discrepancy of nib (7) (8) needle point by button press cap (3) (4).
Claims (1)
1. can be regained by the button cap pressed on compasses and release the compasses of prong for one kind, it is characterized in that: be all provided with button cap (3) (4) at two supporting legs (5) of compasses, (6) top, nib (7) and needle point (8) is connected to by the middle of supporting leg, button press cap (3) (4) are recoverable to nib (7) and needle point (8), thus prevent from being accidentally injured by pinprick when using compasses.
