Abstract
The utility model relates to novel compasses which comprise a drawing leg (1) and a fixed leg (2), wherein the lower end of the fixed leg (2) is provided with a fixed needle (3); the fixed needle (3) and the fixed leg (2) are movably connected with screw holes (5) through screws (4); the upper end of the fixed needle (3) is provided with two sections of screws; the spiral directions of the upper and the lower sections of screws are opposite; and the spiral direction of the upper section of screw is matched with the screw hole (5) on the top end of the fixed leg (2). Because the fixed leg and the fixed needle are movably connected with the screw holes through the screws and the fixed needle is provided with two sections of screws with opposite directions, when the compasses are carried or stored, the sharp end of the fixed needle can be screwed into the screw hole of the fixed leg so as to reduce occurrence of the phenomenon that people is hurt by the fixed needle.
Description
Technical field:
The utility model relates to a kind of stationery, especially a kind of compasses.
Background technology:
Compasses are one of the most frequently used stationery, and traditional compasses have two rule pin: fixed gauge pin and mapping rule pin, the lower end of fixed gauge pin is provided with a locking pin, and the tip of locking pin is comparatively sharp, stabs the people in the process easily carrying or deposit.
The utility model content:
The technical problems to be solved in the utility model is: overcome the drawback that the fixed gauge pin of traditional compasses is easily stabbed the people, a kind of novel bow compass that is difficult for hurting sb.'s feelings is provided.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Novel bow compass comprises mapping rule pin and fixed gauge pin, the lower end of fixed gauge pin is provided with a locking pin, locking pin and fixed gauge pin flexibly connect by screw and silk hole, be provided with two sections screws in the upper end of locking pin, the hand of spiral of upper and lower two sections screw threads is opposite, and the hand of spiral of epimere screw matches with the silk hole on fixed gauge pin top.
After adopting technique scheme, the beneficial effects of the utility model are:
Because fixed gauge pin of this novel bow compass and locking pin flexibly connect by screw and silk hole, and locking pin is provided with two sections screws that direction is opposite, therefore when carrying or deposit compasses, can be screwed onto the tip of locking pin in the silk hole of fixed gauge pin, thereby can reduce the hurt sb.'s feelings generation of phenomenon of locking pin.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a specific embodiment of this novel bow compass.
The specific embodiment:
As shown in Figure 1: novel bow compass comprises mapping rule pin 1 and fixed gauge pin 2, the lower end of fixed gauge pin 2 is provided with a locking pin 3, locking pin 3 flexibly connects by screw 4 and silk hole 5 with fixed gauge pin 2, be provided with two sections screws in the upper end of locking pin 3, the hand of spiral of upper and lower two sections screws is opposite, and the hand of spiral of epimere screw matches with the silk hole 5 on fixed gauge pin 2 tops.
In the process of using this novel bow compass, the tip of locking pin 3 outwards is screwed in the top of fixed gauge pin 2; When carrying or deposit compasses, take off the fixed gauge pin, locking pin 3 is turned made its tip inwardly be screwed in the top of fixed gauge pin 2 then, thereby hide the tip of locking pin 3, so just can reduce the hurt sb.'s feelings generation of phenomenon of locking pin 3.
