[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0020] See also Figure 1 and Figure 2 This embodiment proposes a device for improving the measurement and layout accuracy, including a main frame 1, a movable slide rail 2, a sliding sight 3, a compass system 4, and a level system. In actual operation, this device can cooperate with a total station to conveniently and quickly perform point layout work.

[0021] The main frame 1 is a square frame structure in the shape of a mouth as a whole, which is welded by high-strength and non-deformable square tubes, and plays the role of fixing the movable slide rail 2. Grooves are provided at both ends of the movable slide rail 2, and the structure of the grooves matches the size of the square tube of the main frame 1. The two opposite square tubes of the main frame 1 are engaged in the grooves at both ends of the movable slide rail 2, so that the movable slide rail 2 can slide in the main frame 1. The movable slide rail 2 is connected with a fixing knob 9 for fixing the movable slide rail 2. A first scale mark 5 is provided on a square tube that is slidably connected between the main frame 1 and the movable slide rail 2, and the moving distance of the movable slide rail 2 can be measured.

[0022] A sliding groove 6 penetrating vertically is arranged on the movable slide rail 2 , a second scale mark 7 is arranged on the movable slide rail 2 along the length direction of the sliding groove 6 , and the sliding sight 3 is slidably connected in the sliding groove 6 .

[0023] Specifically, the sliding sight 3 includes an upper prism sighting device 31 and a lower infrared laser sighting device 32, and a sliding sighting device frame 33 is located between the prism sighting device 31 and the infrared laser sighting device 32; the upper prism sighting device 31 is a small high-precision optical right-angle prism that can reflect the measurement signal emitted by the total station. The sliding sighting device frame 33 is embedded in the slide groove 6 and can move along the direction of the moving slide rail 2. The lower infrared laser sighting device 32 is convenient for drawing points and marking after the measurement is completed. The sliding sighting device frame 33 is connected to a tightening knob 34, and the function of the tightening knob 34 is to fix the sliding sight 3 after the layout adjustment.

[0024] The compass system 4 is a set of compasses, which is arranged at a top corner of the main frame 1. The frame can be rotated according to the feedback of the measurement data of the total station, so as to adjust and determine the moving direction.
