Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

In the first embodiment, as shown in fig. 1, the sector gauge comprises a rotating shaft 5, wherein the rotating shaft 5 is sequentially provided with a scale pointer 2, a scale circular plate 3, a telescopic plate 4 and a telescopic ruler 6 from top to bottom, and the scale pointer 2 is fixedly connected with the rotating shaft; the scale round plate 3 and the rotating shaft 5 are arranged concentrically, and the scale round plate 3 is rotationally connected with the rotating shaft 5; the scale round plate 3 is provided with round plate scale marks (shown in figure 2), and the range of the scale marks is 0-360 degrees; the scale pointer 2 is parallel to the scale circular plate 3, and the scale pointer 2 is separated from the scale circular plate 3 by a preset distance; the telescopic plate 4 is adhered to the bottom of the scale round plate 3, and the horizontal axis of the telescopic plate 4 is parallel to the 0 scale mark of the scale round plate 3; one end of the expansion plate 4 is rotatably connected with the rotating shaft 5, and the bottom of the other end of the expansion plate 4 is provided with a fixed supporting leg 8; the telescopic ruler 6 is provided with scale marks, one end of the telescopic ruler 6 is fixedly connected with the rotating shaft 5, and the bottom of the other end of the telescopic ruler 6 is provided with a pen core 7; the telescopic ruler 6 is parallel to the scale pointer 2. The top of the rotating shaft 5 is fixedly provided with a nut. The nut is convenient for an operator to hold the nut to rotate the pointer through the nut, and the line drawing is convenient. One end of the scale pointer 2 is fixedly arranged between the nut and the rotating shaft 5, and the other end of the scale pointer 2 extends out of the nut and is horizontally parallel to the scale round plate 3. The height of the pen core 7 and the height of the fixed support leg are respectively adapted to the height of the rotating shaft 5. The height of the refill 7 and the height of the fixed support leg are respectively set with the height of the rotating shaft 5, so that the fan regular body is stable. The telescopic plate 4 and the telescopic ruler 6 are both telescopic structures (see fig. 3 and 4).

When drawing fan-shaped, earlier zero setting operation is carried out to the sector rule, stretch out the preset distance with expansion plate 4, the preset distance that expansion plate 4 stretches out is greater than the fan-shaped radius length of drawing in advance, it is handheld on the other end of expansion plate 4, the rotatory nut, nut and scale pointer 2 fixed connection for the nut drives scale pointer 2 and rotates, stop rotatory when 0 scale mark of scale pointer 2 directional scale plectane 3, scale pointer 2 this moment, flexible ruler 6 all is parallel with 0 scale mark of scale plectane 3, zero setting operation ends. And then, extending the telescopic ruler 6 by the length of the radius of the pre-drawing sector, and drawing a line segment by the pen core 7 at the bottom of the other end of the telescopic ruler 6, wherein the length of the line segment is the length of the radius of the pre-drawing sector. The nut is rotated, the scale pointer 2 and the telescopic ruler 6 coaxially rotate until the scale pointer 2 points to the pre-drawing fan-shaped angle on the scale circular plate 3, the rotation is stopped, the pen core 7 at the bottom of the other end of the telescopic ruler 6 draws an arc line, then the telescopic ruler 6 is retracted, the pen core 7 can draw another line segment, and the length of the other line segment is the length of the pre-drawing fan-shaped radius. Fig. 5 is a schematic structural view of a sector gauge of the present embodiment rotated 180 degrees. It can be seen that after the sector gauge rotates 180 degrees, the scale pointer 2 and the telescopic ruler 6 both rotate from the right direction (0 scale mark) to the left direction (180 scale mark). When not using the sector rule, only need to contract flexible ruler 6, expansion plate 4 back, the utility model discloses compact structure. In the operation process, the rotating shaft not only plays a role in rotation, but also is matched with the fixed supporting legs 8 of the expansion plate 4 to play a role in stabilizing the structure.

Through adopting the utility model discloses an above-mentioned technical scheme has obtained following profitable effect:

the utility model discloses not only can draw sharp, circle and fan-shaped, but also have the function of protractor, for current measuring tool, the utility model discloses compact structure, the restriction of drawing is little, convenient operation.
