[0026] Two splints 1, the two splints 1 are parabolically bent and the openings are opposite to each other, the two splints 1 can be buckled together to form a channel 11 with an elliptical opening, the end surface of the splint 1 has a plurality of indicating notches 13 spaced apart along the bending direction of the splint 1, the indicating notch 13 on each splint 1 has an indicating notch 13 on the other splint 1 corresponding to it, and the connecting line of the two indicating notches 13 arranged on the two splints 1 coincides with / is arranged parallel to the long axis direction of the opening of the channel 11;

[0027] The control rod 2 is fixed to the clamping plate 1, and the two control rods 2 are crossed and hinged.

[0028] For example, refer to Figure 1and Figure 2 The unbent splint 1 is rectangular, the two long sides of the bent splint 1 are parallel to each other, the short side profile of the bent splint 1 is parabolic, and the position of maximum curvature on the splint 1 is at the midpoint of the wide side of the splint 1, and the openings of the two bent splints 1 are arranged opposite to each other.

[0029] There are two control rods 2, which are arranged perpendicular to the length direction of the channel 11. One end of the control rod 2 is fixedly connected to a clamping plate 1, and the other end extends in a direction away from the clamping plate 1. The two control rods 2 are respectively fixedly connected to two different clamping plates 1, and the control rods 2 are fixedly connected at the midpoint of the length of the clamping plate 1. The two control rods 2 cross in an X shape, and the position where the two control rods 2 cross forms a hinge point of the two control rods 2. The two control rods 2 are in a scissor-shaped hinge structure. The two clamping plates 1 can be opened and closed by the rotation of the two control rods 2, and the channel 11 formed between the two bent clamping plates 1 can also be opened and closed.

[0030] The indicating notch 13 is located at the end of the bent splint 1 and exposed from the end face of the bent splint 1. Each splint 1 has a plurality of indicating notches 13 spaced apart along the short side contour of the splint 1, and the two indicating notches 13 arranged on the two splints 1 form a group, and the connecting lines between each group of indicating notches 13 pass through the port center of the channel 11.

[0031] In this embodiment, two curved splints 1 are brought closer to each other by two fork-hinged control rods 2, and the two curved splints 1 respectively cover the two sides of the twist drill used to open the monitoring hole, and the twist drill is clamped inside the channel 11. The twist drill is erected or lifted by moving and rotating the two control rods 2, and the tip position of the twist drill is determined by the notches on the two splints 1 to meet the opening requirements of the monitoring hole.

[0032] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The opposite side walls of the two clamps 1 have concave lines 12 with two ends extending to the ends of the clamps 1 respectively, and the ends of the concave lines 12 form indicating notches 13.

[0033] For example, refer to Figure 1 and Figure 2The bent splint 1 has a side wall protruding outward and a side wall concave inward, and a concave pattern 12 is formed on the inward concave side wall of the bent splint 1. The concave pattern 12 is arranged along the length direction of the channel 11 and passes through the two end surfaces of the splint 1. For example, a plurality of grooves spaced along the width direction of the splint 1 are milled along the length direction of the splint 1 on the unbent splint 1, and then the splint 1 is bent to form a bent splint 1 having the concave pattern 12, wherein the concave pattern 12 may only exist on one side of the bent splint 1 away from the control rod 2.

[0034] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The side of the clamping plate 1 facing away from the control rod 2 has a gripping portion 5 whose thickness gradually decreases toward the side edge.

[0035] For example, refer to Figure 1 and Figure 2 The side of the splint 1 away from the control rod 2 is partially removed by milling or other machining methods, so that the side of the splint 1 away from the control rod 2 forms an inclined surface whose thickness gradually decreases toward the long side edge of the splint 1, and the edge of the side of the splint 1 away from the control rod 2 forms a blade-shaped grasping portion 5, which penetrates the splint 1 from both ends of the splint 1. The grasping portions 5 on the two splints 1 are opposite to each other and are used to reduce the difficulty of the opened and closed splint 1 to grasp the horizontally placed twist drill.

For example, the edge of the deformation pad 3 away from the control rod 2 can also be thinned to adapt to the structure of the gripping portion 5, and an avoidance opening 6 can also be formed on the deformation pad 3 to adapt to the edge of the fork-shaped clamp 1.

[0041] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The ends of the two control rods 2 facing away from the splint 1 face away from each other, and a bubble level 4 for indicating horizontality is provided on the control rods 2.

[0042] For example, refer to Figure 1 and Figure 2 The control rod 2 includes a clamping section 23 fixedly connected to the clamping section 23, a connecting section 22 fixedly connected to the clamping section 23 and set at an angle, and a control section 21 fixedly connected to the connecting section 22 and set at an angle. The two control rods 2 are hinged by a hinge shaft (not shown in the figure) that simultaneously passes through the two connecting sections 22. The control section 21 and the clamping section 23 are also set at an angle. One end of the two control sections 21 is respectively connected to the two connecting sections 22, and the other ends of the two control sections 21 extend in directions away from each other, that is, when the two clamps 1 are in a closed state, the end of the control rod 2 away from the clamp 1 is flared.
