Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown, the present embodiment includes:

the auxiliary pipe axis positioning structure 1 comprises an inner supporting frame 11, the inner supporting frame 11 is a cross, at least two supporting legs 12 used for supporting the inner wall of the auxiliary pipe 4 are arranged on the outer side of the inner supporting frame 11, and the supporting legs 12 are tubular and perpendicular to the plane of the cross, so that the cross is perpendicular to the axis of the auxiliary pipe 4 as far as possible;

the main pipe axis positioning structure 2 comprises a vertical rod 21, the bottom of the vertical rod 21 is fixedly connected with the inner support frame 11, the vertical rod 21 is hinged with the connecting plate 13 in the center of the cross, an angle locking mechanism is arranged at the hinged position of the vertical rod 21 and the connecting plate 13, the angle locking mechanism comprises an arc-shaped strip-shaped hole 23 formed in the connecting plate 13, a pressing bolt 24 is arranged on the vertical rod 21, the pressing bolt 24 penetrates through the arc-shaped strip-shaped hole 23, and the pressing bolt 24 presses the connecting plate 13 through the end of the pressing bolt to fix the angle of the vertical rod 21; a transverse round rod 22 is fixedly arranged at the top of the vertical rod 21, the transverse round rod 22 is sleeved outside the vertical rod 21 in a sliding manner, the transverse round rod 22 and the vertical rod 21 are fixed through bolts, and a plurality of screw holes for fixing the transverse round rod 22 are formed in the vertical rod 21 so as to adjust the distance between the transverse round rod 22 and the cross;

the line marking executing structure 3 comprises a movable sleeve 31, the movable sleeve 31 is movably sleeved on the transverse round rod 22 in a sliding and rotating mode, a connecting rod 32 is connected to the movable sleeve 31, one end of the connecting rod 32 is fixedly connected with the movable sleeve 31, a line marking plate 33 is fixedly arranged at the other end of the connecting rod 32, the line marking plate 33 is arc-shaped, distances between points on the edge and the axis of the transverse round rod 22 are equal, the distances are the radiuses of the outer walls of the main pipes 5, the main pipes 5 shown by dotted lines in the drawing are only virtual positions of the main pipes 5, and the real main pipes 5 are not placed at the positions when the line marking executing structure 3 is operated.

When the auxiliary pipe axis positioning structure is used, the auxiliary pipe axis positioning structure 1 is placed in the auxiliary pipe 4, the relative position of the transverse round rod 22 and the cross is adjusted by adjusting the angle of the vertical rod 21 and the position of the transverse round rod 22 on the vertical rod 21, so that the axis of the transverse round rod 22 is overlapped with the axis of the designed position of the main pipe 5, and then the angle of the vertical rod 21 and the position of the transverse round rod 22 on the vertical rod 21 are fixed.

Since the distance between each point of the edge of the scribing plate 33 and the axis of the round bar 22 (i.e. the axis of the designed position of the main pipe 5) is equal and is the radius of the outer wall of the main pipe 5, the line drawn from the outer wall of the pipe 4 by the scribing plate 33 is the intersecting line of the pipe 4 and the main pipe 5.
