For the defective that exists in prior art, the purpose of this utility model is to provide the novel bow compass of a kind of convenient use, safety.

For reaching above purpose, the technical scheme that the utility model is taked is:

A kind of novel bow compass, comprise stock, handwriting, described stock comprises fixed support and carrier for drawing-board, described carrier for drawing-board end connects drawing pen, described handwriting is connected by rotating shaft with stock, the draw-in groove that described fixed support end arranges hollow groove and is used in conjunction with slide block, described slide block is fixedly connected with locking pin.

The beneficial effects of the utility model: simple in structure, reasonable in design, well saved the drawing time by the combination of drawing pen and compasses, and fine pilot pin has been protected, safety durable.

Description of drawings

The utility model has following accompanying drawing:

Fig. 1 the utility model structural representation;

Described support bracket fastened structural representation when Fig. 2 the utility model uses state;

Described support bracket fastened structural representation when Fig. 3 the utility model does not use state.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a kind of novel bow compass, comprise stock, handwriting 1, described stock comprises fixed support 3 and carrier for drawing-board 4, described carrier for drawing-board 4 ends connect drawing pen 8, handwriting 1 is connected by rotating shaft 2 with stock, the draw-in groove 9 that described fixed support 3 ends arrange hollow groove 5 and are used in conjunction with slide block 6, and described slide block 6 is fixedly connected with locking pin 7.

During use, slide block 6 is slided into the end (being the end of fixed support 3) of hollow groove 5, be stuck in draw-in groove 9 stationary positioned pin 7.Take pilot pin 7 as the center of circle, the air line distance between pilot pin 7 and drawing pen 8 is that radius is drawn circle, according to the radius needs, regulates the angle between fixed support 3 and carrier for drawing-board 4.When compasses are finished using, lift slide block 6,2 directions move along hollow groove 5 to rotating shaft, in pilot pin 7 enters hollow groove 5 fully, slide block 6 are put into draw-in groove 9, and stationary positioned pin 7 avoids pilot pin 7 to skid off.At this moment, can use handwriting 1 to draw or other work.

Claims (1)

1. novel bow compass, comprise stock, handwriting (1), described stock comprises fixed support (3) and carrier for drawing-board (4), described carrier for drawing-board (4) end connects drawing pen (8), it is characterized in that handwriting (1) is connected by rotating shaft (2) with stock, the draw-in groove (9) that described fixed support (3) end arranges hollow groove (5) and is used in conjunction with slide block (6), described slide block (6) is fixedly connected with locking pin (7).
