[0020] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0021] See attached Figure 1-7 A pipeline hole marking device comprises a magnetic table base 1, a straight rod 2, a scale guide rod 4, a slider 6, a sliding rod 7, a clamping block 8 and a stone pencil 9, wherein the straight rod 2 is fixed on the magnetic table base 1, the scale guide rod 4 is arranged vertically with the straight rod 2, the scale guide rod 4 is rotatably connected to the straight rod 2, the slider 6 is slidably connected to the scale guide rod 4, a scale hole 5 is provided on the top of the slider 6, the sliding rod 7 is arranged vertically with the scale guide rod 4, the sliding rod 7 is slidably connected to the slider 6, the clamping block 8 is fixed on the sliding rod 7, and the stone pencil 9 is fixed on the clamping block 8.
[0022] In this example, refer to the attached Figure 1-7 The pipeline hole marking device includes a magnetic table base 1, a straight rod 2, a deep groove ball bearing 3, a scale guide rod 4, a scale hole 5, a slider 6, a sliding rod 7, a clamping block 8, a stone pencil 9, a top screw A10 and a top screw B11. The lower thread of the straight rod 2 is fastened to the magnetic table base 1, the deep groove ball bearing 3 is installed to the bearing position of the straight rod 2, the scale guide rod 4 is connected to the deep groove ball bearing 3 to achieve 360° rotation, the slider 6 is rotated into the scale guide rod 4, the sliding rod 7 and the clamping block 8 can be connected in the form of welding, and then inserted into the cylindrical hole 12 of the slider 6, the stone pencil 9 is installed in the clamping block 8, and the top screw A10 can fix the stone pencil 9.
[0023] A slider 6 is installed on the scale guide rod 4. A scale hole 5 is provided on the top of the slider 6. The scale on the scale guide rod 4 can be observed through the scale hole 5 to determine the size of the required circle. A top screw B11 is provided on the side of the slider 6 to fix the position of the slider 6 to prevent the slider 6 from moving during operation. The sliding rod 7 is installed in the cylindrical hole 12 on the side of the slider 6 and can move freely up and down with the height of the position.
