[0032] The connection between the positioning rod 6 and the positioning groove 8 is a snap-fit ​​connection, and the positioning rod 6 is a square in a top view, and the width of the positioning rod 6 is smaller than the diameter of the through hole 7. Through the snap-fit ​​connection between the positioning rod 6 and the positioning groove 8, the installation position of the drill body 3 can be preliminarily positioned, which is convenient for subsequent fixed installation work.

[0033] The connection between the limiting hole 9 and the straight rod 11 is a snap-fit ​​connection, and the straight rod 11 is distributed at equal angles on the support shaft 1.

[0040] according to Figure 1-3 and Figure 6 , and then manually pull the sleeve 16 to make the sleeve 16 slide upward on the outside of the support shaft 1, so that the sleeve 16 and the support frame 15 are separated from each other, and at the same time, the sleeve 16 pulls the pull rope 13, so that the pull rope 13 slides smoothly through the support frame 15, so that the pull rope 13 pulls the straight rod 11, and then the straight rod 11 slides outward in the support shaft 1, so that the straight rod 11 and the limiting hole 9 are slid and separated, and at the same time, the second magnet 12 on the straight rod 11 is separated from the first magnet 10, and the positioning work of the drill body 3 is released;

[0041] according to Figure 1-6 Then the staff manually pulls the drill body 3, so that the drill body 3 can slide and separate smoothly from the receiving hole 2 through the positioning ring 4, so that the positioning rod 6 and the positioning groove 8 on the drill body 3 can slide and separate. At the same time, the spacer ring 5 automatically slides down in the receiving hole 2 due to the sliding out of the drill body 3. The sliding position of the spacer ring 5 can be limited by the positioning ring 4, thereby completing a series of tasks.
