The top of the L-shaped support plate 1 is fixedly connected to the controller 12. The first electric telescopic rod 7, the drive motor 11 and the pressure sensor 18 are all electrically connected to the controller 12. The controller 12 receives the signal of the pressure sensor 18 to control the first electric telescopic rod 7 and the drive motor 11. The control principle is the existing technology and is not elaborated here. The utility model can simultaneously press the hose before drilling through a series of structures, without the need for manual fixation, thereby improving the stability of subsequent drilling, and can effectively control the drilling depth according to the drilling needs, which can effectively avoid the situation where the hose is pierced by drilling too deep when drilling on the surface.

[0027] Working principle: When using, when punching a hole on the surface of the hose, the hose to be punched is placed on the corresponding core rod 3, and the core rod 3 is inserted into the through hole 2. Then, the second electric telescopic rod 5 is started in the positive direction. The output shaft of the second electric telescopic rod 5 drives the support block 4 and the anti-slip rubber on it to move upward until they are in active contact with the bottom of the hose. The second electric telescopic rod 5 is stopped. At this time, the support block 4 supports the core rod 3 with the hose.

[0028] Then, the vertical position of the limit ring 14 is adjusted according to the depth of the hole to be drilled. During the adjustment, the T-shaped screw 16 is rotated in the opposite direction. While the T-shaped screw 16 rotates, it moves to the right. The T-shaped screw 16 drives the rectangular pressing block 15 and the friction rubber to move to the right and separate from the drill rod 13, thereby releasing the fixation of the limit ring 14. At this time, the limit ring 14 can be moved upward or downward. When the limit ring 14 moves to the required position by observing the value on the scale line 1301, the movement of the limit ring 14 can be stopped. Then, the T-shaped screw 16 is rotated forward, so that the rectangular pressing block 15 drives the friction rubber to move to the left until it is aligned with the drill rod 13. The right side of the rod 13 is in close contact. Under the action of the friction force between the friction rubber and the drill rod 13, the limit ring 14 can be fixed. At this time, the distance between the bottom of the limit ring 14 and the top of the moving block 17 is the depth of the hole that can be drilled. After adjustment, the first electric telescopic rod 7 can be started in the positive direction. The output shaft of the first electric telescopic rod 7 drives the mounting plate 8 to move downward. The mounting plate 8 drives the pressing block 6 to move downward through the two springs 10. When the pressing block 6 drives the corresponding anti-slip rubber to move downward until it contacts the top of the hose, the pressing block 6 is restricted from continuing to move. At this time, the mounting plate 8 that continues to move is between the two L-shaped guides. The mounting plate 8 squeezes the compression block 6 through the two springs 10 to achieve compression of the hose. When the mounting plate 8 moves downward, the drill rod 13 is driven downward by the drive motor 11. At the same time, the drive motor 11 is turned on. The output shaft of the drive motor 11 drives the drill rod 13 to rotate, so that the drill rod 13 rotates and moves downward. When the drill rod 13 rotates and moves downward, the hose is punched. The drill rod 13 also drives the limit ring 14 to move downward. When the limit ring 14 moves downward and contacts the moving block 17, it squeezes the moving block 17. The moving block 17 squeezes the pressure sensor 18, and the pressure sensor 18 detects the squeezing force and transmits the detected squeezing force to the controller 12. When the squeezing force is detected, the controller 12 controls the first electric telescopic rod 7 and the drive motor 11 to close and stop drilling. By automatically controlling the first electric telescopic rod 7 and the drive motor 11 to close when drilling a hole to a required depth, effective control of the drilling depth can be achieved, which can effectively avoid the situation where the hose is penetrated by drilling too deep when drilling a hole on the surface. In addition, the hose is pressed and fixed synchronously before drilling, and manual fixation is not required, thereby improving drilling stability.

[0029] In addition, when it is necessary to punch through the top of the hose or the top and bottom at the same time, the position of the limiting ring 14 can be adjusted again. When the distance between the bottom of the limiting ring 14 and the top of the movable block 17 is greater than the inner diameter thickness of the hose or the diameter of the hose, the hose can be punched through. This method of adjusting the punching depth can make holes of different depths according to the needs of use, thereby improving the scope of application.

[0030] After drilling, the first electric telescopic rod 7 is started in the reverse direction, so that the drill rod 13 and the pressing block 6 are both transformed to move upward, and the drill rod 13 and the pressing block 6 are separated from the hose upward, and the hose can be removed from the core rod 3.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
