Abstract
The utility model provides a pair of compasses capable of drawing back a positioning needle. The pair of the compasses is in a hollow structure at the position of a positioning needle support leg. A strip groove is formed in one side of the positioning needle support leg. An adjusting sliding handle connected above the positioning needle is located in the sliding groove. A turncap which is used for adjusting the positioning needle to stretch out and draw back and fixing the positioning needle is arranged on the lower portion of the positioning needle support leg. When the pair of compasses is used, the positioning needle can be adjusted to stretch out and draw back the support leg through loosening and tightening of the turncap, so the positioning needle can stretch out when the pair of compasses is in use, the positioning needle can draw back to the support leg when the pair of compasses is put away, the phenomenon that a finger is stabbed is avoided, and safe and reliable of putting away of the pair of compasses can be achieved.
Description
Technical field
The utility model relates to a kind of compasses, specifically a kind of collapsible compasses of deciding pin.
Background technology
Compasses are to rely on decide deciding the pin location and using of pin supporting leg below, decide the conehead of pin due to sharp, and are slightly careless, will stab finger, and compasses are when idle, and pin is exposed owing to deciding, and this has stayed a very unsafe hidden danger to the folding and unfolding compasses.
Summary of the invention
The utility model provides a kind of collapsible compasses of deciding pin, can allow compasses when idle, can will decide pin and be retracted to folding and unfolding in supporting leg.
The utility model comprise compasses decide pin and top decide the pin supporting leg, the technical scheme that adopts is: described compasses are being decided the structure that the pin supporting leg is a hollow, be provided with a bar groove deciding pin supporting leg one side, decide the adjusting sliding handle that pin top connects and be positioned at the bar groove, be used for regulating and decide the turncap that pin is flexible and fix deciding to be provided with below the pin supporting leg one.
The beneficial effects of the utility model are embodied in: during use, loosening and packing by turncap, can regulate and decide stretching out and the retraction supporting leg of pin, to decide pin in the time of can allowing thus compasses use stretches out, to decide pin during folding and unfolding is retracted in supporting leg, avoid stabbing the phenomenon of finger, favourable safe and reliable folding and unfolding compasses.
