Abstract
The utility model discloses an embedded compass. A lead core clamping pipe embedding hole is formed on the lower part of a compass leg made of metal materials; a lead core clamping pipe and a clamping nut are made of plastic materials; and the lead core clamping pipe is embedded in the lead core clamping pipe embedding hole. According to the utility model, the embedded combination ensures the metal rigidity and high use accuracy of the compass, and the lead core is convenient to fill, so that the embedded compass has good popularization values.
Description
Technical field
The utility model relates to drawing instrument, is the invention about embedded compasses.
Background technology
Traditional compass for drawing is all made with metal material, because compass foot is identical with material with the lead for retractable pencil grip tube, people are with the clamping of screwing of compass foot and lead for retractable pencil grip tube screw bolt and nut, and this infrastructure cost is higher, and the junction also is easy to become flexible; The part compasses change plastic material into and make in recent years, compass foot and lead for retractable pencil holder are established as a whole, cause the compasses serviceability to be difficult to reach requirement because of plastic material is soft.
Summary of the invention
The purpose of the utility model is to provide a kind of serviceability more superior than metal compasses, and the cost of making is lower, the embedded compasses that metal material and plastic material combine.
The purpose of the utility model is achieved in that with metal material makes compass foot; Establish lead for retractable pencil grip tube embedded hole in the compass foot bottom, make lead for retractable pencil grip tube and binding nut with plastic material, the lead for retractable pencil grip tube that plastic material is made embeds lead for retractable pencil clamping pore; Because the compasses holder and the clamping nut tube wall of plastics are thicker; Lead for retractable pencil clamping pore and metal compass foot can have certain angle, and the lead for retractable pencil hole of compasses lead for retractable pencil grip tube is a through hole, so that pack lead for retractable pencil into from the through hole rear portion.The embedded compasses of the utility model, its compass foot is made with metal material, and the lead for retractable pencil grip tube adopts plastic material to make, and both embedded combinations have guaranteed the metal rigidity of compasses, obtain the low cost of plastic production again.Both combine firmly for it, have guaranteed both integraty and the high accuracy in the use, and the dress lead for retractable pencil is also convenient, has excellent generalization values.
Description of drawings

Fig. 2 is the lead for retractable pencil grip tube of compasses and the structural representation of binding nut
The specific embodiment
Make compass foot 1 with metal material; Establish lead for retractable pencil grip tube embedded hole 2 in compass foot 1 bottom, make lead for retractable pencil grip tube 4 and binding nut 5 with plastic material, the lead for retractable pencil grip tube 3 that plastic material is made embeds lead for retractable pencil grip tube embedded hole 2; Because the compasses lead for retractable pencil holder 4 of plastics is thicker with binding nut 5 tube walls; Lead for retractable pencil clamping pore 2 can have certain angle with metal compass foot 1, and the lead for retractable pencil hole 3 of compasses lead for retractable pencil grip tube 4 is a through hole, so that pack lead for retractable pencil 6 into from the through hole rear portion.
Claims (3)
1. one kind by the embedded compasses of making compass foot with metal material; It is characterized in that establishing lead for retractable pencil grip tube embedded hole in the bottom that makes compass foot with metal material; Make lead for retractable pencil grip tube and binding nut with plastic material, the lead for retractable pencil grip tube is embedded in the lead for retractable pencil clamping pore.
2. embedded compasses according to claim 1 is characterized in that lead for retractable pencil clamping pore and metal compass foot can have certain angle.
3. embedded compasses according to claim 1, the lead for retractable pencil hole that it is characterized in that the lead for retractable pencil grip tube is a through hole.
