[0021] The fixing structure 2 includes a first screw 201 and a circular ring 202. The top of the first screw 201 is fixedly connected to the bottom of the fixing seat 1. The outer wall of the first screw 201 is threadedly connected to the inner wall of the circular ring 202. The circular ring 202 is subjected to force and rotates up and down through the outer wall of the first screw 201. The bottom of the outer wall of the first screw 201 is rotatably connected to a straight plate 203. After the position of the straight plate 203 is fixed, the bottom of the outer wall of the first screw 201 rotates through the top bearing of the straight plate 203. The rear end face of the straight plate 203 is fixedly connected to a first clamping plate 204. The inner wall of the straight plate 203 is threadedly connected to a second screw 205. The outer wall of the second screw 205 is fixedly connected to a handle 206. The handle 206 is convenient for driving the second screw 205 to rotate. The front of the outer wall of the second screw 205 is rotatably connected to a second clamping plate 207. The second screw 205 is subjected to force and rotates through the inner wall bearing of the second clamping plate 207.

[0022] By fixing the structure 2, the bottom of the straight plate 203 is fitted with the top of the basic rail, and the front of the first clamping plate 204 is fitted with the outer wall of the basic rail. Then, the second clamping plate 207 is held to rotate the handle 206. The rotating handle 206 causes the second screw 205 to rotate toward the inner wall of the straight plate 203. The rotating second screw 205 moves the second clamping plate 207 backward, so that the rear of the second clamping plate 207 is pressed against the other side of the basic rail. Then the ring 202 rotates downward on the outer wall of the first screw 201, so that the bottom of the ring 202 is pressed against the top of the straight plate 203, completing the positioning of the reduction value measuring ruler, reducing the difficulty of using the reduction value measuring ruler, and ensuring the normal use of the reduction value measuring ruler.

[0023] A level 8 is fixedly connected to the lower part of the outer wall of the movable seat 7. There is an air bubble in the middle of the level 8. By checking whether the air bubble is located in the center of the level 8, it can be judged whether the measuring ruler is level as a whole. A third screw 9 is threadedly connected to the top of the movable seat 7. The bottom of the third screw 9 is tightly against the top of the crossbeam 4. The third screw 9 fixes the movable seat 7 and the crossbeam 4. The measuring structure 3 includes a ruler bar 301 and a ruler frame 302. The lower part of the outer wall of the ruler bar 301 is plugged into the inner wall of the ruler seat 5. The outer wall of the ruler bar 301 is slidably connected to the inner wall of the ruler frame 302. The ruler frame 302 can slide up and down on the outer wall of the ruler bar 301. Observe the ruler frame 30 The reading of the inner wall ruler 301 is the second vertical value of the measuring track. A vertical rod 304 is inserted at the bottom of the ruler 301. A circular plate 305 is fixed at the bottom of the vertical rod 304. A spring 306 is sleeved on the outer wall of the vertical rod 304. The two ends of the spring 306 are respectively fixed to the bottom of the ruler 301 and the top of the circular plate 305. After the circular plate 305 is forced to move upward, it rebounds by the elastic force of the spring 306. The front of the ruler frame 302 is threadedly connected with a first screw 303. The rear end face of the first screw 303 is tightly pressed against the front of the ruler 301. The first screw 303 plays a role in fixing the ruler frame 302 and the ruler 301.

[0024] Working principle:

[0025] Reduced value measuring tape installation:

[0026] The bottom of the straight plate 203 is made to fit with the top of the basic rail, and the front of the first clamping plate 204 is made to fit with the outer wall of the basic rail. Then, the second clamping plate 207 is held and the handle 206 is rotated. The rotating handle 206 causes the second screw 205 to rotate toward the inner wall of the straight plate 203. The rotating second screw 205 moves the second clamping plate 207 backward, so that the rear of the second clamping plate 207 is pressed against the other side of the basic rail. Then the ring 202 is rotated downward on the outer wall of the first screw 201, so that the bottom of the ring 202 is pressed against the top of the straight plate 203, and the positioning of the reduction value measuring ruler is completed.

[0027] When measuring the pointed rail, the lowered value measuring ruler is used:

[0028] After the fixing of the fixing seat 1 end is completed, the second screw 6 is rotated upward through the top of the ruler seat 5, so that the bottom of the second screw 6 is separated from the top of the beam 4, and then the ruler seat 5 is moved on the outer wall of the beam 4, so that the ruler seat 5 moves above the sharp track, and then the second screw 6 is rotated downward through the ruler seat 5, so that the second screw 6 is tightly pressed against the beam 4 to complete the fixing of the ruler seat 5. At this time, the bottom of the circular plate 306 will fit with the top of the sharp track, and the elastic force of the spring 306 will make the circular plate 305 and the sharp track fit stably. Then the ring 202 is rotated upward on the outer wall of the first screw rod 201, so that the ring 202 is separated from the straight plate 203, and then the movable seat 7 is pushed to make the horizontal plate 4 rotate with the fixing seat 1. At this time, check the level 8, so that the bubble inside is located at the center of the level 8, and then the ring 202 is rotated downward on the outer wall of the first screw rod 201, so that the bottom of the ring 202 is pressed against the top of the straight plate 203. At this time, check the reading of the ruler bar 301 in the ruler frame 302, which is the lowering value of the sharp track relative to the wing rail.

[0029] When measuring the center rail, the lower value measuring ruler is used:

[0030] Fix the fixed seat 1 to the basic rail on one side, and then the bottom of the movable seat 7 fits with the basic rail on the other side. At this time, the lowering value measuring scale is balanced. According to the above operation, the circular plate 305 is above the point rail, and the circular plate 305 contacts the top of the point rail. At this time, the reading of the scale bar 301 inside the scale frame 302 is the lowering value of the heart rail relative to the wing rail.

[0031] Embodiment 2:

[0032] See also Figure 1-4 : In this embodiment, a reduction value measuring instrument also includes a limit pin 10, and the outer wall of the limit pin 10 is fixedly connected to the upper front side of the ruler 301.

[0033] Working principle:

[0034] When the ruler frame 302 moves up and down on the outer wall of the ruler bar 301 , the limiting pins 10 can limit the ruler frame 302 to prevent the ruler frame 302 from being separated from the outer wall of the ruler bar 301 .
