[0031] In the embodiment of the utility model, the connecting assembly 4 is arranged at the connecting position of the upper mounting surface 101 and the prism head 2 and the connecting position of the lower mounting surface 102 and the tripod 3, that is, two assemblies are respectively arranged at the upper mounting surface 101 and the lower mounting surface 102 of the bidirectional range finder 1; the prism head 2 and the tripod 3 are detachably connected to the bidirectional range finder 1 by the connecting assembly 4, which can realize the portability and stability of the device, facilitate the replacement of the corresponding prism head 2, and forcibly center the center of the prism head 2, the center of the bidirectional range finder 1 and the vertical center of the tripod 3, so that the three points are coaxial to improve the measurement accuracy. Of course, the tripod 3 is made of aluminum alloy material, and can also be made of carbon fiber material, so that it is lighter and easier to carry.

[0033] As shown in Figures 1-3 In an embodiment, the connecting assembly 4 includes a first connector 401 and a second connector 402 which are detachably connected, the first connector 401 is selectively arranged at one of the upper mounting surface 101 and the prism head 2, and the second connector 402 is arranged at the other one, and the first connector 401 is selectively arranged at one of the lower mounting surface 102 and the tripod 3, and the second connector 402 is arranged at the other one. Specifically, in order to detachably connect the upper mounting surface 101 and the prism head 2, and the lower mounting surface 102 and the tripod 3, the embodiment defines that the connecting assembly 4 therebetween includes the first connector 401 and the second connector 402, the first connector 401 and the second connector 402 belonging to the same group are arranged at the opposite end surfaces of the upper mounting surface 101 and the prism head 2 (or the first connector 401 and the second connector 402 belonging to the same group are arranged at the opposite end surfaces of the lower mounting surface 102 and the tripod 3; in the embodiment, since the two connecting assemblies 4 are the same, the connecting assembly 4 arranged between the upper mounting surface 101 and the prism head 2 is taken as an example in the following; it can be understood that the connecting assembly 4 between the lower mounting surface 102 and the tripod 3 is also applicable).

[0034] For a standard large prism head, as shown in Figure 2As shown, the prism head 2 is detachably fixed with the first connector 401, and the upper mounting surface 101 is detachably fixed with the second connector 402.

In addition, since the relative movement direction of the two joints is along the up-down direction, the movement direction of the limiting protrusion 406 extending into or out of the limiting slot 405 is perpendicular to the above movement direction, i.e. along the left-right direction or along the front-back direction. Of course, in order to facilitate the rotation of the limiting protrusion 406, anti-skid lines or rotating handles can be arranged on the end of the limiting protrusion 406 protruding out of the plug hole 403. Preferably, the limiting slot 405 is arranged around the axis of the plug-in part 404. In other embodiments, the above limiting structure can also be arranged at the connecting assembly 4 between the lower mounting surface 102 and the tripod 3, for improving the structural stability and strength at this position.

[0038] As shown in the drawings, Figure 1 As shown in the drawings, in an embodiment, the tripod 3 is provided with a centering rod 5. Specifically, in order to facilitate rapid centering, the centering rod 5 is arranged at the vertical center of the tripod 3 in the embodiment, and the centering rod 5 can be used to quickly calibrate and center the center line. At the same time, the tripod 3 is adjustably arranged at the centering rod 5, for adjusting the overall height of the tripod 3; in addition, corresponding scale lines can be arranged on the centering rod 5, and the lowest height is 60 cm (the center height of the prism), so that the device height can be checked at any time. Preferably, the tripod 3 is a leveling tripod 3; preferably, the tripod 3 is provided with a leveling bubble.
