[0011] Refer to Figure 1 Figure 2 Figure 3 Figure 4The described distance measuring instrument for road and bridge construction that is easy to adjust is characterized in that: it includes a connecting outer tube 1 and an adjusting device 2 inserted at the center of the inner circle of the connecting outer tube 1. At the middle of the upper side of the side surface of the adjusting device 2, there is a connecting pillar 3 connected. At the center of the upper surface of the connecting pillar 3, there is an installation platform 4 connected. At the middle of the front edge of the upper surface of the installation platform 4, there is a horizontal water column 5 connected. At the middle of the left edge of the upper surface of the installation platform 4, there is a fixed vertical plate 6 connected. At the middle of the right side of the upper surface of the installation platform 4, there is a movable clamping plate 7 inserted. The connecting outer tube 1 includes an inserting tube 1-1, a rubber pad 1-2, a sliding hole 1-3, and a clamping groove 1-4. At the center of the lower surface of the inner part of the inserting tube 1-1, there is a rubber pad 1-2 connected. On the left and right middle parts of the outer surface of the inserting tube 1-1, there are sliding holes 1-3 symmetrically arranged. Inside each sliding hole 1-3, there are several clamping grooves 1-4 vertically and evenly distributed on the front and back surfaces. The inside of the clamping groove 1-4 is in a semi-circular shape. The adjusting device 2 includes a housing 2-1, a partition 2-2, a spring 2-3, and a clamping post 2-4. At the middle of the inside of the housing 2-1, there is a partition 2-2 connected. At the centers of the left and right surfaces of the partition 2-2, there are springs 2-3 symmetrically connected. At the center of the outer surface of each spring 2-3, there is a clamping post 2-4 connected. The clamping post 2-4 is in a convex shape. The housing 2-1 is inserted inside the inserting tube 1-1. The clamping post 2-4 is inserted into the sliding hole 1-3 and the clamping groove 1-4. The connecting pillar 3 is connected at the middle of the upper side of the side surface of the housing 2-1. The housing 2-1 is in a circular tube shape. The length of the housing 2-1 matches the inner diameter size of the inserting tube 1-1. The installation platform 4 includes a cross plate 4-1, a sliding groove 4-2, a lead screw 4-3, and a turntable 4-4. At the middle of the right side of the upper surface of the cross plate 4-1, there is a sliding groove 4-2. At the middle of the right side surface of the cross plate 4-1, there is a lead screw 4-3 inserted. At the center of the right side surface of the lead screw 4-3, there is a turntable 4-4 connected.

[0012] In use, first, the staff places the rangefinder on the upper surface of the cross plate 4-1 on the installation platform 4. At the same time, the rangefinder is in contact with the fixed vertical plate 6. Then, the staff rotates the turntable 4-4 to drive the lead screw 4-3 to rotate. At the same time, when the lead screw 4-3 rotates, it drives the movable clamping plate 7 to slide in the chute 4-2 so that the movable clamping plate 7 and the fixed vertical plate 6 clamp the rangefinder. Then, the staff observes the horizontal water column 5 to adjust the cross plate 4-1 to be horizontal. Then, the staff presses the clamping post 2-4 on the adjusting device 2 and inserts the clamping post 2-4 into the outer shell 2-1. At the same time, the clamping post 2-4 is inserted into the sliding hole 1-3 on the connecting outer tube 1. Then, when the staff pushes the clamping post 2-4, the outer shell 2-1 drives the connecting support column 3 to move in the insertion tube 1-1. At the same time, the connecting support column 3 drives the rangefinder to move through the cross plate 4-1 to adjust the height. After the adjustment is completed, the staff releases the clamping post 2-4, and at the same time, the spring 2-3 pushes the clamping post 2-4 so that the thick end of the clamping post 2-4 is inserted into the card slot 1-4 for clamping.
