It should be noted that, the end of the leg 300 is the end of the leg 300 close to the pipe body 100; the number of the legs 300 may be three or more, and four, five, etc. may be selectively used for the legs 300 according to the use needs.

Referring to fig. 1 and 2, since the contour edge of the long through hole 111 encloses a closed loop, the part of the pipe body 100 below the long through hole 111 encloses a complete ring-shaped shell, so that a notch is prevented from being formed at the lower end of the pipe body 100, deformation in the radial direction is not easy to occur at the lower part of the pipe body 100, and the structural strength near the connection position between the pipe body 100 and the three cutting seats 200 is improved, thereby improving the bearing capacity of the tripod. In this embodiment, the profile shape of the long through hole 111 is substantially rectangular, the length direction of the long through hole 111 is consistent with the length direction of the pipe body 100, so as to provide enough space for the stand bar 300 to rotate upwards and downwards relative to the pipe body 100, and the positioning push rod 400 penetrating the three cutting seats 200 is used to push against the end parts of all stand bars 300 so as to stabilize the stand bars 300 in the storage state or the unfolding state.
