Specific embodiment

Certainly, implement any technical solution of the utility model embodiment it is not absolutely required to and meanwhile reach above all Advantage.

In order to make those skilled in the art more fully understand the technical scheme in the embodiment of the utility model, below in conjunction with this Attached drawing in utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, shows So, described embodiment is only the utility model embodiment a part of the embodiment, instead of all the embodiments.Based on this reality With the embodiment in new embodiment, this is all should belong in those of ordinary skill in the art's every other embodiment obtained The range of utility model embodiment protection.

Further illustrate that the utility model embodiment implements below with reference to the utility model embodiment attached drawing.

Fig. 1 is a kind of structural schematic diagram of Simple compasses provided by the embodiment of the utility model.

As shown in Figure 1, comprising: fixed part 11, support rod 12, interconnecting piece 13, through-hole 14.

Wherein, fixed part 11 is used to the Simple compasses being located in drafting face；One end of support rod 12 with it is described solid Determine the connection of portion 11；Interconnecting piece 13 is connected on the support rod 12, and the relatively described support rod 12 of the interconnecting piece 13 can be rotated； Through-hole 14 is arranged on the interconnecting piece 13, and for installing drawing tool, the drawing tool on the drafting face for drawing Circle, the quantity of the through-hole 14 are multiple.

Fixed for convenience in the present embodiment, fixed part 11 can be adsorbent, and the adsorbent is used for Simple compasses On the drafting face of being adsorbed on, the face of drafting can be horizontal drafting face, or the drafting face of other angles, such as say class hour Blank etc..Adsorbent is specifically as follows sucker, and the use of sucker increases the versatility of Simple compasses.Certainly, adsorbent may be used also Think magnet-type adsorbent or adhesive type adsorbent etc., the present embodiment is herein without limiting.In addition, when fixed part is absorption When body, adsorbent can be integrally formed with support rod 12.

It in the present embodiment, stores for convenience, interconnecting piece 13 can be chain linkage section, and the chain linkage section includes more A sequentially connected connection unit.Specifically, the through-hole 14 is provided on each connection unit.

It in the present embodiment, connects for convenience, connection unit can be lantern ring, and through-hole runs through lantern ring.Specifically, it draws Tool can be pen, and the pen is mounted in the through-hole of the lantern ring.Pen can be common pencil, ball pen, crayon, wax Pen, chalk etc., as long as through-hole can be inserted in pen.

In the present embodiment, in order to improve the versatility of Simple compasses, lantern ring is circular ring.In other realities of the utility model It applies in example, lantern ring may be polygon lantern ring.

It should be understood that chain linkage section can be straight by the lantern ring of one end when connection unit is lantern ring Female connector is located on the support rod, is rotatably connected to realize with support rod；And it as shown in Fig. 2, can be on lantern ring Including connection buckle, thus realize removably connected between two neighboring lantern ring and lantern ring and support rod between it is dismountable Connection.

Fig. 3 is a kind of usage scenario schematic diagram of Simple compasses provided by the embodiment of the utility model.

It should be noted that the fixed part of Simple compasses is adsorbent 11 in the present embodiment, interconnecting piece is chain linkage section 13, connection unit is lantern ring, and drawing tool is pen 21.Simple compasses provided in this embodiment use process is as follows:

1) Simple compasses being directly adsorbed on drafting face by adsorbent 11, adsorbent 11 is integrated with support rod 12, Then the center of support rod 12 is the center of circle, so that it is determined that the position in the center of circle；

2) pen 21 is inserted into the through-hole 14 of a lantern ring of chain linkage section 13, makes Stylus contact in drafting face, chain is straightened Shape linkage section 13, then the distance of pen tip to 12 center of support rod is the radius of circle, so that it is determined that the radius of circle；

3) center rotating of the direction around support rod 12 of the arrow along figure of pen 21 is controlled by hand, pen 21 drives chain connection Section is around one circle of the rotation of support rod 12, to draw circle on drafting face.

In the present embodiment, complete it is primary draw circle after, above-mentioned steps 2 can be repeated), 3), and by the way that pen 21 is inserted In the through-hole 14 for entering another lantern ring of chain linkage section 13, to change round radius, to draw different size of circle.

A kind of Simple compasses provided by the embodiment of the utility model comprising: fixed part, the fixed part is used for will be described Simple compasses are located on drafting face；Support rod, one end of the support rod are connect with the fixed part；Interconnecting piece, the company Socket part is connected on the support rod, and the relatively described support rod of the interconnecting piece can be rotated；Through-hole, the through-hole are arranged in institute It states on interconnecting piece, for installing drawing tool, the drawing tool is used in the drafting face upper drawing circle, the quantity of the through-hole It is multiple.Simple compasses provided by the embodiment of the utility model, structure simple and flexible, without complicated processing technology thereof；And Easy to operate, the crowd for being suitble to this operational capacity of preschool child poor carries out picture circle operation, both improves preschool child Draw round success rate simultaneously, fixed part no longer uses similar cutting-edge structure etc., also improves safety.

It should be noted that the interconnecting piece in above-described embodiment is also possible to the structure of non-chain, for example, one have it is more The ruler etc. of a through-hole.

It should be noted that the chain linkage section in above-described embodiment can be other chain linkage sections, such as chain Deng.
