[0025] The motion mechanism 2 includes a white writing rod 201, a scale 202 is provided on one side of the white writing rod 201, an indicator rod 203 is provided on the bottom side of the scale 202, a cross bar 204 is provided on the front of the indicator rod 203, a marker pen 205 is provided on the end of the cross bar 204 away from the indicator rod 203, the marker pen 205 is fixedly connected to the cross bar 204, a threaded rod 206 is provided on the top of the fixed plate 5, a lifting plate 207 is provided on the top of the threaded rod 206, and a wire rope 208 is provided on the top of the cross bar 204.

[0026] The other end of the marker pen 205 is fixedly connected to the crossbar 204 , and the other end of the marker pen 205 passes through the hole 3 and contacts the white writing rod 201 .

[0027] A connecting plate 209 is provided on the top front of the bracket 1, and the top surface of the connecting plate 209 is horizontally collinear with the top surface of the bracket 1. A limiting plate 210 is provided on the top of the connecting plate 209, and the steel wire rope 208 passes through the limiting plate 210, and the steel wire rope 208 is in contact with the limiting plate 210 and the connecting plate 209 respectively. The threaded rod 206 is threadedly connected to the lifting plate 207, and a sealing plate 211 is provided on the top of the bracket 1. The sealing plate 211 is fixedly connected to the bracket 1 by screws, and the top of the white writing rod 201 is fixedly connected to the sealing plate 211, and the white writing rod 201 is located inside the bracket 1.

[0028] A measuring rod 212 is provided on one side of the threaded rod 206. The bottom end of the measuring rod 212 is horizontally collinear with the bottom end of the bracket 1. The top end of the measuring rod 212 is fixedly connected to the lifting plate 207. A support plate 213 is fixedly provided on one side of the bracket 1 close to the indicator rod 203.

[0029] When working, first move the whole device to the place where measurement is required, and make the measuring rod 212 be located above the hole, then rotate the threaded rod 206, because the threaded rod 206 is threadedly connected with the lifting plate 207, the lifting plate 207 moves downward through the rotation of the threaded rod 206, so that one end of the lifting plate 207 moves downward along the slide groove 4, and in the process of the lifting plate 207 moving downward, the steel wire rope 208 fixedly connected to the lifting plate 207 is stretched at the same time, so that the top of the steel wire rope 208 moves downward, and The bottom end of the wire rope 208 moves upward, so that the wire rope 208 moves simultaneously with the measuring rod 212. During the movement of the wire rope 208, the wire rope 208 is in contact with the connecting plate 209 and the limiting plate 210 respectively, which ensures the movement of the wire rope 208. The bottom end of the wire rope 208 is fixedly connected to the indicator rod 203, so that the indicator rod 203 moves upward at the same time. Because the indicator rod 203 is fixedly connected to the marking pen 205 through the cross bar 204, the cross bar 204 and the marking pen 205 move upward at the same time. When the indicator rod 203 moves upward, one end of the indicator rod 203 contacts the scale 202, so that the indicator rod 203 can move upward along the scale 202, and the distance of movement can be clearly known through the scale 202. When the measuring rod 212 is stationary, the depth of the hole can be known through the distance of movement, and the depth can be accurately known through the scale 202, thereby improving the accuracy. When the marker pen 205 moves upward, since the marker pen 205 passes through the hole groove 3 and contacts the white writing rod 201, through the upward movement of the marker pen 205, The marker pen 205 can leave marks on the white writing rod 201, because the marker pen 205 and the indicator rod 203 are on the same horizontal line and move upward together, so the movement height of the marker pen 205 and the indicator rod 203 is equal. Then, the screws on the sealing plate 211 are removed, and the sealing plate 211 is separated from the bracket 1. The sealing plate 211 can be removed, and the white writing rod 201 fixedly connected to the sealing plate 211 moves upward at the same time, and the marks on the white writing rod 201 can be wiped off, which is convenient for subsequent use.
