[0023] Please refer to Figures 1-5 The utility model provides a technical scheme: a tripod for mine surveying engineering, including placing table 1, the lower end fixedly connected with circular ring 2 of placing table 1, the center fixedly connected with first telescopic link 3 of placing table 1 lower end, the outer surface of first telescopic link 3 is provided with steady pole 5, the bottom fixedly connected with support frame 4 of circular ring 2, the inner wall fixedly connected with fastening structure 6 of placing table 1.

[0024] The specific setting and function of support frame 4 and fastening structure 6 will be described below.

[0025] In the embodiment: support frame 4 includes movable block 41, movable block 41 is rotatably connected with support rod 42 through the pivot in the inside, the inner wall of support rod 42 is slidably connected with extension rod 43, the bottom fixedly connected with fixed stake 44 of extension rod 43, the outside fixedly connected with moving device 45 of extension rod 43 bottom, the end fixedly connected with connecting assembly 46 of support rod 42 away from movable block 41.

[0026] The effect reached by the above components is that movable block 41 enables support rod 42 to rotate flexibly relative to circular ring 2, facilitating the adjustment of the unfolding angle of the tripod to adapt to different terrains. Extension rod 43 can slide within support rod 42, combined with fixed stake 44, to penetrate the ground and enhance the grip of the tripod on soft or uneven ground, ensuring stability. Moving device 45 facilitates the movement of the tripod, and connecting assembly 46 is used to connect and fix support rod 42 and extension rod 43, ensuring structural stability.

[0027] Specifically, support frame 4 has three groups distributed circumferentially at the bottom of circular ring 2, and moving device 45 includes connecting block 451 fixedly connected to the outer surface of the bottom of extension rod 43, connecting block 451 is movably connected with mounting block 452 through the pivot in the inside, and mounting block 452 is fixedly connected with moving wheel 453 on the surface.

[0028] The effect reached by the above components is that moving wheel 453 is movably connected through connecting block 451 and mounting block 452, making the tripod more convenient to move in the mine environment. When moving is needed, moving wheel 453 is rotated to fit the ground, and when not in use, it can be retracted to allow fixed stake 44 to function, increasing the flexibility of the device when in use.

[0029] Specifically, the telescopic end of first telescopic link 3 is provided with a thread, and the bottom end of first telescopic link 3 is fixedly connected with a limiting block.

[0030] The effect achieved by the above-mentioned components is that the thread design of the telescopic end, matched with nuts and other accessories, can accurately adjust the length of the first telescopic rod 3, thereby accurately adjusting the height of the placement table 1 to adapt to different measurement height requirements. The limiting block can prevent the first telescopic rod 3 from being excessively stretched during elongation, avoid damage to the internal structure, and ensure normal use.

[0036] The effect achieved by the above-mentioned components is that when the measuring instrument is placed on the placement table 1, the silica gel piece 63 contacts with the instrument to increase the friction and prevent the instrument from sliding. The buffer spring 62 can buffer the impact force when the instrument is placed and the shaking caused by external vibration during the measurement, avoiding damage to the instrument due to collision and playing a protective role for the measuring instrument.

[0037] Specifically, the fastening structure 6 has four groups distributed in a circular manner on the inner wall of the placement table 1.
