[0029] The mobile measuring component 7 can also be set to models with multiple lengths of the scale ruler 705 to cope with different depth measurement requirements.

[0030] Furthermore, telescopic brackets 5 are provided on both sides of the bottom of the slide rail 1, and the movable ends of the telescopic brackets 5 are fixedly connected to the frustum support legs 6. The telescopic brackets 5 are telescopic structures with adjustable height, which is a prior art. The frustum support legs 6 can adapt to more ground conditions, and can be placed or fixed by inserting the frustum support legs 6 into the ground according to the situation.

[0031] Furthermore, a magnetic conical surface 4 is provided on the slide rail 1 at a position in front of the track groove 3 .

[0032] Furthermore, one end of the rotating shaft core 709 extends out of the side wall of the slider 701 , and a section of the rotating shaft core 709 extending out of the slider 701 is connected to a coil spring 708 , and a cover is provided outside the coil spring 708 .

[0033] Furthermore, a first sliding groove 710 is provided at the bottom of the side of the slider 701 along the length direction of the slide rail 1, and a control rod 703 is slidably provided in the first sliding groove 710, and a first spring 712 is connected between the control rod 703 and the bottom wall of the first sliding groove 710, and two second sliding grooves 711 communicating with the first sliding groove 710 are provided at the bottom of the slider 701 along the width direction of the slide rail 1, and a push rod 704 is slidably provided in each second sliding groove 711, and a section of the control rod 703 located inside the slider 701 is provided with two connecting ears 715, and each push rod 704 is provided with a rotating groove 713 at one end facing the control rod 703, and a support rod 714 is rotatably connected in each rotating groove 713, and the other end of each support rod 714 is rotatably connected to the nearest connecting ear 715.
