The cavity for filling ink is formed between the nib stated；Grip part includes connecting rod, and described connecting rod one end is offered and institute
The external screw thread that internal thread is engaged is stated, the other end of the connecting rod, which is provided with inside rotatable end socket, the end socket, to be opened up
Have in annular groove, the annular groove and be provided with ball.
More preferably, the sucker suction is when working face, and the center line of the screw rod is parallel with the working face.
More preferably, the circle chi of drawing also includes being set in the shell outside the paintbrush.
More preferably, the screw rod has a variety of different pitch specifications.
The utility model draws circle chi, the paintbrush and screw flight connection there is provided a kind of many pore radius of planar design,
And limited block is provided with, and when the limited block pushes against the paintbrush, Stability Analysis of Structures, accurate size, the limited block is away from described
During paintbrush, the paintbrush is also moved when rotation along the screw rod direction, it is possible to achieve the drafting of helix.

Embodiment
Below in conjunction with the accompanying drawings, an embodiment of the present utility model is described in detail, it is to be understood that this
The protection domain of utility model is not limited by embodiment.
As shown in Figure 1-Figure 3, a kind of many pore radius of planar design draw circle chi, including transmission mechanism, paintbrush 20 and grip part
13；Transmission mechanism includes screw rod 11, the sucker 10 for being hinged on the one end of screw rod 11 and the locating piece 30 coordinated with the screw thread 22 of screw rod 11,
The center line of screw rod 11 offers scale groove 12 with being hinged on central axis, screw rod 11, and the bottom surface of scale groove 12 is provided with scale
Line, the one end of screw rod 11 away from sucker 10 offers internal thread 22；Paintbrush 20 include with the screw thread 22 of screw rod 11 coordinate axle center part,
Peripherally and outwardly extend the first circular shell of formation from one end of axle center part and peripherally and outwardly extend shape from the other end of axle center part
Into the second circular shell, be provided with circumference between the neighboring of the first circular shell and the neighboring of the second circular shell
The nib 23 of extension, is formed for filling between outer wall 21, the first circular shell, the second circular shell and the nib 23 of axle center part
The cavity of ink 24；Grip part 13 includes connecting rod 133, and the one end of connecting rod 133 offers the outer spiral shell being engaged with internal thread 22
Line, the other end of connecting rod 133 is provided with to offer inside rotatable end socket 131, end socket 131 and set in annular groove, annular groove
Ball 132 is equipped with, when sucker 10 is adsorbed in working face, the center line of screw rod 11 is parallel with working face, and paintbrush 20 also includes
A shell for the outside of paintbrush 20 is set in, screw rod 11 has a variety of different pitch specifications.
In use, sucker 10 is adsorbed on working face, when needing picture bowlder, rotate at paintbrush 20 to corresponding scale,
Then rotational positioning block 30 makes it be pushed against on side of the paintbrush 20 away from sucker 10, hand gripping end socket 131, rotary screw 11,
