Further, in the present invention, the upper ends of the support legs 20 are installed in the first installation holes 12, and at the same time, the depth of the upper ends of the support legs 20 protruding into the first installation holes 12 can be finely adjusted. Therefore, the length of the supporting leg 20 positioned outside the first mounting hole 12 can be finely adjusted, the supporting leg 20 is beneficial to adapting to the complex environment of the ground, and the application range of the tripod 100 is effectively improved.

According to the tripod 100 of the embodiment of the present invention, the fixing legs 11 are disposed below the fixing base 10, so that the fixing legs 11 effectively define the extending direction of the supporting legs 20, which is beneficial to preventing the supporting legs 20 from rotating, and effectively improving the overall stability of the tripod 100.

In some embodiments, as shown in fig. 1, 2 and 5, tripod 100 further comprises an abutment 30. One end of the abutment 30 is provided with a second mounting hole 31, the upper end of the support leg 20 is disposed in the second mounting hole 31, and the other end of the abutment 30 is disposed in the first mounting hole 12.
