[0028] Refer to the instruction manual Figure 1-Figure 5 The utility model provides a support seat 2, a servo electric cylinder 3, an instrument mounting seat 4, a support leg 5, a conical plug 6, a support sleeve 7, a spring 8 and an arc-shaped auxiliary plate 9. The support seat 2 supports the servo electric cylinder 3, and the servo electric cylinder 3 supports the bottom of the instrument mounting seat 4. Adjusting the extension and retraction of the servo electric cylinder 3 can drive the instrument mounting seat 4 to be raised and lowered, thereby realizing the height adjustment of the measuring device. The operation is convenient and fast, and there is no need to consider the problems of part damage and inconvenience in adjustment during height adjustment. The support legs 5 on the support frame 1 are supported at the bottom of the support seat 2. When the equipment is in use, it is only necessary to fix the corresponding measuring instrument on the top of the instrument mounting seat 4, and then adjust the expansion angle of the support legs 5 to determine the approximate height of the measuring instrument and realize stable support for the bottom of the measuring instrument. When the support legs 5 are in contact with the hard ground, the support sleeve 7 is protectively supported on the outside of the conical plug 6. The support sleeve 7 first contacts the ground, and the squeezing force of the support sleeve 7 on the hard ground interacts with each other. The support sleeve 7 contracts upward, and the arc-shaped auxiliary plate 9 on one side of the servo electric cylinder 3 of the support sleeve 7 is in contact with the hard ground for support, and at the same time, the conical plug 6 extends out of the support sleeve 7 to contact and support the ground, which can effectively ensure the stability of the measuring device; when the support frame 1 is placed on a soft ground for use, the support sleeve 7 first contacts and resists the ground, and with the gravity of the support frame 1 and the measuring device or the downward pressure applied by the staff, the support sleeve 7 moves upward, the spring 8 is compressed, and the conical plug 6 extends out of the support sleeve 7, and the conical plug 6 is inserted into the soft ground. The arc-shaped auxiliary plate 9 on the outer wall of the support sleeve 7 is in contact with the ground and resists, which can effectively press down the soft ground outside the conical plug 6, which can effectively enhance the support stability and safety of the support leg 5; after the support frame 1 is stored, the spring 8 rebounds to push the support sleeve 7 downward, and the support sleeve 7 protects the outside of the conical plug 6, which can effectively prevent the conical plug 6 from causing damage to the staff when it is in use and idle;

[0029] The support ball 14 provides rotational support for the arc-shaped auxiliary plate 9, which can effectively ensure that the arc-shaped auxiliary plate 9 fits against the ground after contacting the ground, thereby improving the stability of the support leg 5. The coordinated use of the support shaft and the torsion spring can effectively provide a torsional support force for the arc-shaped auxiliary plate 9, so that the tightening effect when the arc-shaped auxiliary plate 9 is against the ground is better, and the stability of the support leg 5 is further enhanced; the two ends of the support rod 16 are respectively rotatably connected between the support leg 5 and the slider 17. When adjusting the inclination angle of the support leg 5, one end of the support rod 16 moves with the support leg 5, and the other end of the support rod 16 drives the slider 17 to slide along the slide groove 18. The support rod 16 can support the support leg 5, which can effectively enhance the stability of the support leg 5. The through groove 21 provides a movement space for the support rod 16 to ensure the smoothness of the movement of the support rod 16.
