Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a technical solution: the utility model provides a multi-functional swift compasses, including a pedestal 1, pedestal 1 is transparent material, be convenient for observe the reading of first pointer 9 and second pointer 10, the mid-mounting of pedestal 1 has a center pin 2, there are first support 3 and second support 4 on the center pin 2 respectively movable mounting, a lateral wall of second support 4 has set firmly scale 19, set up scale 19, can measure length, extend the function of compasses, fixed foot 5 is installed to the bottom of first support 3, the bottom joint of second support 4 has pencil core 6.

As shown in fig. 1-2, an outer wall of the seat body 1 is fixedly provided with a dial 7 and an angle scale 8, the dial 7, the angle scale 8 and the central shaft 2 are concentrically arranged, the first bracket 3 is fixedly provided with a first pointer 9, the second bracket 4 is fixedly provided with a second pointer 10, and the lengths of the first pointer 9 and the second pointer 10 are both between the radiuses of the dial 7 and the angle scale 8.

As shown in fig. 3-4, a hollow rotating handle 11 is fixedly arranged at the top of the seat body 1, and is formed by fastening two half shells, so that the eraser 14 can be maintained or replaced conveniently, a first spring 12 is fixedly connected to the inner wall of the hollow rotating handle 11, a card box 13 is fixedly connected to the top of the first spring 12, and the eraser 14 is clamped in the card box 13.

As shown in fig. 3-4, a rotatable dial 15 is mounted on the inner wall of the hollow stem 11, a second spring 16 is fixedly connected to one side of the dial 15, one end of the second spring 16, which is far away from the dial 15, is connected to the inner wall of the hollow stem 11, a pull rope 17 is fixedly connected to the middle of the dial 15, and one end of the pull rope 17 penetrates through the hollow stem 11 and is fixedly connected to a pull block 18 outside the hollow stem 11.

When the drawing device is used, as shown in fig. 1, the first support 3 and the second support 4 are firstly drawn in use, in the drawing process, the first indicator needle 9 and the second indicator needle 10 respectively rotate along with the first support 3 and the second support 4, the drawing radius is obtained through the numerical difference (the difference between the second indicator needle 10 and the first indicator needle 9 is taken as an actual radius value) on the dial 7 corresponding to the first indicator needle 9 and the second indicator needle 10, and the argument can be obtained through the difference on the angle scale 8, so that drawing is facilitated, and the drawing time is shortened.

When the eraser 14 needs to be used, as can be seen from fig. 3-4, firstly the pulling block 18 is pulled to drive the pulling rope 17 to pull, so as to drive the shifting piece 15 to rotate towards the inner wall of the hollow rotating handle 11, and then the second spring 16 is driven to compress, so that the shifting piece 15 can release the restriction on the card box 13, at this time, the eraser 14 is ejected from the hollow rotating handle 11 due to the deformation recovery function of the first spring 12, so as to be convenient to use, when the eraser is not used, the eraser 14 is pressed to compress the first spring 12, so as to retract the eraser 14 into the hollow rotating handle 11, and in the process of sliding down the card box 13, the shifting piece 15 is contacted, at this time, the second spring 16 is pressed, until the card box 13 moves to be below the shifting piece 15, the second spring 16 is reset to expand the shifting piece 15, so that the card box 13 is restricted by the shifting piece 15.
