Abstract
The utility model relates to a pair of three-point compasses, which belongs to a drawing tool. A U-shaped frame of a pair of two-point compasses is added with a compass leg (8) which is supported by a fastening screw (2), a cylinder (3), a spring (4), a column (5) and a rotating rod (6). The compass leg (8) can swing as well as rotate and can determine the position of a third point on a plane quickly and can shift the three points. The utility model can draw pictures rapidly and conveniently.
Description
The utility model belongs to drawing instrument.
" Three point compass " structure of application number 94222612.7 is simple inadequately in the prior art, uses very flexible.
The purpose of this utility model is: provide a kind of simple in structure, can determine on the face thirdly the position fast and with 3 Three point compasses of displacement rapidly.
Formation of the present utility model: on the U-shaped frame of bipod compasses, increase a compass foot, the support of compass foot (8) is installed on the U-shaped frame of bipod compasses (1), support is by pinching screw (2), cylinder (3), spring (4), cylinder (5) and dwang (6) are formed, end suit dwang (6) at cylinder (3), mounting spring (4) in cylinder (3), other end fixed cylinder (5) at cylinder (3), cylinder (5) is installed on the pinching screw (2), pinching screw (2) is installed on the U-shaped frame of bipod compasses (1), go up by screw (7) installation compass foot (8) at dwang (6), go up at compass foot (8) needle point (9) is installed.In the middle of the cylinder axial circular hole is arranged, right-hand member has shoulder hole.Dwang (6) is cylindrical, and an end has round boss, and the other end has axial U-lag, one side U-lag has a circular hole, another side has screwed hole.One end of cylinder (5) has the screwed hole of installation pinching screw (2).
Compared with the prior art, the utility model is simple in structure, can determine on the face thirdly the position fast and with 3 displacements rapidly, easy to use flexibly, the compass foot (8) of pulling down increase promptly recovers the function of bipod compasses.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is right views of accompanying drawing 1.
Embodiment of the present utility model: as shown in Figure 1, dwang (6) and spring (4) are installed in cylinder (3), cylinder (5) is fixed in the stomidium of cylinder (3), pinching screw (2) is contained on the U-shaped frame of bipod compasses (1), and screw in the screwed hole of cylinder (5), in the U-lag of dwang (6), compass foot (8) is installed by screw (7), go up installation needle point (9) at compass foot (8), compass foot (8) can be swung in the U-lag on the dwang (6), and dwang (6) also can drive compass foot (8) and rotate in cylinder (3).
