[0040] Specifically, before starting the work with the strong opener, first need to determine and mark the specific location of the need to punch, then slide the connecting plate 202, make sure the alignment of the planned punch area, after the connecting plate 202 is installed and fixed, can use the multiple suction cups 10 on the mounting plate 9 to suction and fixed on the punch soon to be carried out the object, so that the object can remain stable during the punching process, will not move or offset, after the preparation work is completed, start punching, in the process of punching, the operation of the telescopic rod 6 will move down, while extruding the second spring 8, the second spring 8 is to avoid the position of the center drill 11 during the punching process any unnecessary change or offset, so as to ensure the accuracy of the punching, when the punching operation is completed, the second spring 8 will rebound because of its own elastic force, which will make the arc plate 12 return to its original position, in the process of punching, the chip groove 14 will collect the debris generated in the process of punching, these debris will be guided into the chip groove 21 and discharged later, through the above process, it can ensure that there is no deviation in the positioning process, improve the accuracy of positioning.

[0041] With reference to Figure 1 , Figure 2 and Figure 5 , the telescopic mechanism 2 comprises a supporting plate 201, which is slidingly connected to the inner wall of the hollow tube 4; the top end of the base 1 is fixedly connected with a first spring 207, the top of the first spring 207 is fixedly connected with a connecting square plate 206, the installation of the first spring 207 enables the connecting square plate 206 to be reset; the left and right ends of the connecting square plate 206 are both rotatably connected with a rotating short column 204, the sides away from each other of the two rotating short columns 204 are both fixedly connected with a special-shaped block 203; the inner wall of the first spring 207 is equally provided with a plurality of special-shaped grooves 205 at the left and right ends, the special-shaped grooves 205 enable the special-shaped block 203 to be clamped; the top of the special-shaped block 203 is fixedly connected with a connecting plate 202, the top of the connecting plate 202 is fixedly connected with the bottom of the supporting plate 201; the top of the hollow tube 4 is installed with a mounting ring 18;

[0042] Specifically, in actual operation, when the length of the hole opener needs to be shortened, the operator can push the connecting short column 17 downward, and as the connecting short column 17 moves downward, the supporting plate 201 also moves downward, and the movement of the supporting plate 201 drives the special-shaped block 203 connected thereto, and since the special-shaped block 203 is clamped in the special-shaped groove 205, the special-shaped block 203 is prevented from automatically rebounding to the original position during downward movement. On the contrary, if the length of the hole opener needs to be increased, the operator needs to lift the connecting short column 17 upward, and since the connecting plates 202 on both sides are fixedly connected to the supporting plate 201, when the connecting short column 17 moves upward, the supporting plate 201 will first drive the special-shaped block 203 to move upward, and then by rotating the short column 204, the overall transverse distance can be shortened. With the rebounding action of the first spring 207, the special-shaped block 203 will gradually move upward until it reaches the desired position. Through the above process, the length of the hole opener can be adjusted to adapt to different hole opening requirements, thereby avoiding frequent replacement of hole openers of different lengths, thereby improving work efficiency. The installation of the mounting ring 18 makes the connecting short column 17 and the hollow pipe 4 more stable.

[0043] Referring to Figure 1 , Figure 2 and Figure 3 , the outer wall of the connecting column 5 is provided with a thread 16, and the outer wall of the base 1 is provided with a mounting groove 3 around;

[0044] Specifically, the thread 16 is provided to make the hole opening smoother, and the mounting groove 3 is provided to make the installation more convenient and stable.

[0045] Working principle: Before using the powerful hole opener, first determine the position to be punched, then slide the connecting plate 202 to align it with the position to be punched, and after installation, the multiple suction cups 10 installed by the mounting plate 9 will be attached to the object to be punched. Start punching, then move the extension rod 6 downward and press the second spring 8 to avoid the position of the center drill 11 changing during punching; after punching is completed, the arc-shaped plate 12 is restored to its original position by the rebounding of the second spring 8. During punching, the chip collecting groove 14 will collect the debris and discharge it through the chip discharge groove 21; through the above process, deviation during positioning is avoided, the positioning accuracy is improved, and the work efficiency is improved;

[0046] When the length of the hole opener needs to be changed, the connecting short column 17 is pushed down, the support plate 201 will continue to move down, due to the engagement of the special-shaped block 203 with the special-shaped groove 205, and due to the shape, the special-shaped block 203 will move down and will not automatically rebound, if the length of the hole opener needs to be lengthened, the connecting short column 17 is lifted up, due to the fixed connection on both sides through the connecting plate 202, when it moves up, the support plate 201 will first move up with the special-shaped block 203, through the rotation of the rotating short column 204, the overall transverse distance is shortened, and then through the rebound of the first spring 207, the special-shaped block 203 will gradually move up until it moves to the required place, through the above process, the length of the hole opener can be changed, the hole opener does not need to be replaced frequently, and the work efficiency is improved.

[0047] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical scheme recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
