[0030] The second vertical rod 30 has a telescopic adjusting structure, which comprises a sleeve 31 and a sleeve rod 32, the lower end of the sleeve rod 32 is slidingly sleeved in the sleeve 31, the upper end of the sleeve 31 is rotationally connected with a lifting nut 311, the lifting nut 311 is threadedly matched with the sleeve rod 32, rotating the lifting nut 311 can drive the sleeve 31 to slide relative to the sleeve rod 32, a straight slot 312 is arranged on the side wall of the sleeve 31 along the length direction thereof, a height difference scale 313 is arranged on the side of the straight slot 312 along the length direction thereof, a height difference pointer 321 is fixedly connected to the lower end of the sleeve rod 32, the height difference pointer 321 is slidingly arranged in the straight slot 312, the height difference pointer 321 is matched with the height difference scale 313, and is used for displaying the telescopic amount of the second vertical rod 30, the middle line of the height difference scale 313 is a 0 scale line, and when the height difference pointer 321 is indicated at the 0 scale line, it indicates that the length of the second vertical rod 30 is equal to the length of the first vertical rod 10.

[0031] The upper end of the sleeve rod 32 is fixedly connected with an indicating disc 322, the indicating disc 322 is rotationally connected with a large gear 323 and a small gear 324, the axes of the large gear 323 and the small gear 324 are arranged along the vertical direction of the second vertical rod 30, and the two are meshed with each other, wherein a socket sleeve 3231 is fixedly connected to the large gear 323 along the radial direction thereof, the side wall of the socket sleeve 3231 is threadedly connected with a fastening screw 3232, a horizontal pointer 3241 is fixedly connected to the small gear 324 along the radial direction thereof, and the indicating disc 322 is provided with a horizontal scale line 325 matched with the horizontal pointer 3241, when the horizontal pointer 3241 is indicated at the horizontal scale line 325, the socket sleeve 3231 is perpendicular to the second vertical rod 30, and since the diameter of the large gear 323 is greater than that of the small gear 324, the rotation angle of the small gear 324 is always greater than that of the large gear 323, and the advantage is that the sensitivity of the horizontal pointer 3241 is high, the rotation angle of the socket sleeve 3231 can be amplified and displayed, and thus the accuracy of the display result is higher.

[0032] The telescopic connecting rod 50 is a telescopic long straight rod, one end of the telescopic connecting rod 50 is provided with an axle hole along the vertical direction of the length direction, the pin shaft 12 is rotationally matched with the axle hole, so that the telescopic connecting rod 50 can rotate around the axis of the pin shaft 12, the other end of the telescopic connecting rod 50 is inserted into the socket sleeve 3231, and the telescopic connecting rod 50 and the socket sleeve 3231 are locked and fixed through the fastening screw 3232, so that the telescopic connecting rod 50 can rotate around the axis of the large gear 323, and in the assembled state, the axis of the pin shaft 12 is parallel to the axis of the large gear 323.

[0033] It should be noted that the aforementioned “length of the first vertical rod 10” actually refers to the distance from the lower end of the first vertical rod 10 to the axis of the pin shaft 12, and the aforementioned “length of the second vertical rod 30” actually refers to the distance from the lower end of the second vertical rod 30 to the axis of the large gear 323.

[0034] When using this measuring device, firstly, the first upright 10 is vertically erected at one measuring position, and the second upright 30 is vertically erected at another measuring position. Then, the lifting nut 311 on the second upright 30 is rotated until the horizontal pointer 3241 coincides with the horizontal scale line 325. Since the telescopic connecting rod 50 and the socket sleeve 3231 are aligned in the same length direction, the telescopic connecting rod 50 is in a horizontal state when the socket sleeve 3231 is perpendicular to the second upright 30. At this time, the height difference scale 313 indicated by the height difference pointer 321 is the height difference between the two measuring positions. If the height difference pointer 321 indicates the 0 mark in the height difference scale 313, it means that the height difference between the two measuring positions is 0. If the height difference pointer 321 indicates the height difference scale 313 above the 0 mark, it means that the position of the second upright 30 is lower than the position of the first upright 10. If the height difference pointer 321 indicates the height difference scale 313 below the 0 mark, it means that the position of the second upright 30 is higher than the position of the first upright 10.

[0035] After the measuring device is used up, the pull ring 121 on the pin 12 can be pulled to separate the telescopic connecting rod 50 from the first upright rod 10, and the fastening screw 3232 on the socket sleeve 3231 can be loosened to separate the telescopic connecting rod 50 from the second upright rod 30 for easy storage.

Both the first support 20 and the second support 40 are foldable tripods with leveling functions. A first bubble level 21 is provided on the top surface of the first support 20. A first upright 10 is slidably connected to the first support 20 in a direction perpendicular to the top surface of the first support 20. When the first upright 10 is supported, the top surface of the first support 20 is adjusted to be horizontal with the help of the first bubble level 21, which makes it easier to adjust the first upright 10 to be vertical.

[0037] The top surface of the second support 40 is provided with a second bubble level 41. The second upright 30 is slidably connected to the second support 40 in a direction perpendicular to the top surface of the second support 40. When the second upright 30 is supported, the top surface of the second support 40 is adjusted to be horizontal with the help of the second bubble level 41, which makes it easier to adjust the second upright 30 to be vertical.
