Description

Rope automatic pull-type compasses

Technical field

The present invention relates to a kind of drawing tool fields, more particularly to a kind of rope automatic pull-type compasses.

Background technique

Compasses are one of common drawing tools, existing compasses be usually by handle, the support rod being connect with handle and Swingle composition.In use, the needle point of support rod is located on the center of circle, support rod and swingle are separated to required radius, Rotatable handle is held again, and the pencil or pencil-lead on swingle will draw required circle.However traditional compasses are due to support Bar and swingle are by the way of hinged, and with being increased using the time for compasses, support rod and the hinged of swingle slowly fluff, So that the figure that compasses are drawn is not accurate, and the center of circle is not also fixed easily；Traditional compasses need ruler to be subject in use Auxiliary just can determine that the radius of drawn circular arc, and there are inconvenient problems with use；Existing compasses generally only have the function of picture circle, It cannot achieve the interception other functions such as line segment and circular arc line, there are the drawbacks that function is relatively simple；Especially pupil exists The circle of half or so can only be substantially drawn using a handle is rotated when traditional compasses, at least needs to exchange the position of hand again Rear half-turn can just be painted by setting, i.e., pupil is described a circle with existing compasses and cannot substantially be settled at one go.

Summary of the invention

Purpose of the invention is to overcome the shortcomings in the prior art, provides that a kind of structure is simple, easy to use, function Various and laborsaving timesaving rope automatic pull-type compasses.

To achieve the above object, the present invention provides a kind of rope automatic pull-type compasses and is provided with handle, support rod and rotation Bull stick, vertical between the support rod and swingle to be socketed with graduated scale, graduated scale is flexibly connected by casing with support rod, is carved Degree ruler is flexibly connected by covering frame with swingle；Described sleeve pipe is fixed on support rod, and fixation is fixedly installed on the outside of casing Plate is fixed on the left of plate upper end and is provided with the Horizontal limiting plate fixed vertical with fixed plate, the centre bit of fixed plate It installs and is equipped with the elasticity bolt one fixed vertical with fixed plate, elasticity bolt one is provided through graduated scale one end and has interior spiral shell The screw rod one of line and the nut one being flexibly connected with screw rod one in screw thread；
