Abstract

A multifunction marking gauge relates to a marking gauge, aiming at solving the problem that the prior marking gauge is incapable of drawing various graphics such as an ellipse, a triangle or a polygon, etc. The utility model mainly comprises a central stationary shaft, a locking pin, a pencil, a hold-down nut of template die, a template die and a main amplification bracket, wherein, the main amplification bracket adopts the structure of a pantograph which uses three pairs of connecting bars to form two corresponding parallelogram structures, and each two of the connecting bars have the same length. The utility model also comprises a clip rod, a pullback spring, a fixing hole for pencil. The utility model has the advantage of drawing various graphics such as an ellipse, a triangle or a polygon, etc.

Description

Multifunctional compass

Technical field: the utility model relates to a kind of planing.

Background technology: existing planing all is to draw circle just, when people will draw ellipse or triangle, polygonal and other figure, then do not have plan available.

Summary of the invention: to be that design is a kind of can draw planing of ellipse or triangle, multiple figure such as polygonal to the purpose of this utility model.

Above-mentioned purpose can be realized by following proposal: in the lower end of central fixed shaft 1 locking pin 10 is arranged, we establish template die hold-down nut 9 at the middle part of central fixed shaft, template die 8 is fixed on the middle part of central fixed shaft by hold-down nut, a main end that amplifies support 4 is sleeved on the top of central fixed shaft, the main support that amplifies adopts the pantograph structural principle, utilize three pairs of isometric in twos connecting rods to connect to form the parallelogram sturcutre (playing the pantograph effect) of two correspondences by movable axis, bar 7 is installed on the movable axis 3 that is positioned at master's amplification support central authorities, one end of kelly is against on the template die edge, extension spring 2 also is housed on the movable axis 3, the other end of extension spring is fixed on the central fixed shaft, the main other end that amplifies support is established a fixing hole 5, and pen 6 is contained in the fixing hole.

Will at first get the template die of these figures ready in order to mark ellipse, triangle, polygonal and other figure with the utility model, select when using.

The utility model has the advantages that the figure that to draw ellipse, triangle, multiple shape such as polygonal.

Description of drawings: Fig. 1 is that master of the present utility model looks schematic diagram;

Fig. 2 is a schematic top plan view of the present utility model.

The specific embodiment: locking pin 10 is arranged in the lower end of central fixed shaft 1, establish template die hold-down nut 9 at the middle part of central fixed shaft, template die 8 is fixed on the middle part of central fixed shaft by hold-down nut, a main end that amplifies support 4 is sleeved on the top of central fixed shaft, the main support that amplifies adopts the pantograph structural principle, utilize three pairs of isometric in twos connecting rods to connect to form the parallelogram sturcutre of two correspondences by movable axis, bar 7 is installed on the movable axis 3 that is positioned at master's amplification support central authorities, one end of kelly is against on the template die edge, extension spring 2 also is housed on the movable axis 3, the other end of extension spring is fixed on the central fixed shaft, the main other end that amplifies support is established a fixing hole 5, and pen 6 is contained in the fixing hole.

The template die of making ellipse, triangle, multiple shape such as polygonal in addition as required is standby.
