[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-4 A perforation mechanism for corrugated cardboard boxes includes an end plate mechanism 1. A handle mechanism 2 and a narrow-diameter perforation tube 3 are respectively fixedly installed on the middle portions of both end faces of the end plate mechanism 1. The end of the narrow-diameter perforation tube 3 away from the end plate mechanism 1 has a perforation oblique groove 4. A shrinking external thread tube 5 is fixedly sleeved on the surface of the narrow-diameter perforation tube 3 near the end plate mechanism 1. An expanding external thread tube 6 is fixedly sleeved on the surface of the narrow-diameter perforation tube 3 near the perforation oblique groove 4. A stop is slidably sleeved on the surface of the narrow-diameter perforation tube 3. The support ring 8 has a shrinking internal thread tube 7 and an expanding internal thread tube 9 fixedly installed at both ends. The shrinking internal thread tube 7 and the shrinking external thread tube 5 are threaded together, and the expanding internal thread tube 9 and the expanding external thread tube 6 are threaded together. The end of the expanding internal thread tube 9 away from the support ring 8 is fixedly connected to a connecting support ring 11. The outer edge of the connecting support ring 11 away from the expanding internal thread tube 9 is fixedly connected to a wide-diameter opening sleeve 12. The end of the wide-diameter opening sleeve 12 is provided with a cross-cutting tool groove.

[0022] In this utility model, the end plate mechanism 1 includes a supporting end plate 101 and a protective edge ring 102. The protective edge ring 102 is fixedly sleeved on the outer ring of the supporting end plate 101, and the outer ring of the protective edge ring 102 is a convex arc-shaped structure.

[0023] More specifically, by setting a protective ring 102 to be fixedly sleeved on the outer ring of the support end plate 101, the protective effect is improved and the hand is prevented from being scratched.

[0024] In this utility model, the handle holding mechanism 2 includes a handle holding tube 201, a handle rubber sleeve 202 and an anti-slip ring groove 203. The handle rubber sleeve 202 is fixedly sleeved on the surface of the handle holding tube 201, and the anti-slip ring groove 203 is opened around the surface of the handle rubber sleeve 202.

[0025] More specifically, by setting an anti-slip ring groove 203, the handle rubber sleeve 202 is fixedly sleeved on the surface of the handle tube 201, providing a grip for hand handling, making it less likely to slip off the hand during operation and making it easier to operate.

[0026] In this utility model, both ends of the retaining ring 8 are fixedly connected with fastening washers 10. The surface of the fastening washers 10 is attached to the inner wall of the shrinking internal thread tube 7 or the expanding internal thread tube 9, and the fastening washers 10 at both ends of the retaining ring 8 overlap with the ends of the shrinking external thread tube 5 and the expanding external thread tube 6, respectively.

[0027] More specifically, by setting the fastening washers 10 at both ends of the retaining ring 8 to overlap with the ends of the shrinking external threaded tube 5 and the expanding external threaded tube 6 respectively, the wide-diameter opening sleeve 12 can maintain good stability when it is shrunk or extended.

[0028] In this utility model, one end of the handle tube 201 is fixedly connected to the support end plate 101, and the other end of the handle tube 201 is fixedly installed with an anti-drop end seat 15.

[0029] More specifically, by setting the anti-detachment hand seat 15 at the end of the handle tube 201, the handle is less likely to detach from the hand during the pulling process when the hole is opened, thus improving the stability of the operation.

[0030] In this utility model, the cross tool groove includes a 30-degree groove 13 and a 60-degree groove 14. The 30-degree groove 13 and the 60-degree groove 14 are opened in a cross shape. The 30-degree groove 13 is opened at three-quarters of the depth of the wide-diameter opening sleeve 12, and the 60-degree groove 14 is opened at one-quarter of the depth of the wide-diameter opening sleeve 12.

[0031] More specifically, the 30-degree inclined groove 13 and the 60-degree inclined groove 14 are set in an intersecting manner, which can avoid the situation of slow opening and damage to the outer cardboard part due to the large resistance during the large-diameter opening operation.

[0032] Working principle: When making a small-diameter hole, the shrink internal thread tube 7 is twisted so that it is threaded onto the surface of the shrink external thread tube 5. This causes the retaining ring 8 to drive the fastening washer 10 to slide spirally, and the fastening washer 10 to press against the end of the shrink external thread tube 5 to achieve fixation. This causes the wide-diameter hole-making sleeve 12 to shrink, exposing the hole-making oblique groove 4 of the narrow-diameter hole-making tube 3. One end of the hole-making oblique groove 4 can then be inserted into the corrugated cardboard board that needs to be holed, thereby piercing and achieving the small-diameter hole-making operation.

[0033] When drilling a large-diameter hole, the shrinking internal thread tube 7 is spirally disengaged from the surface of the shrinking external thread tube 5. The retaining ring 8 is slid on the surface of the narrow-diameter opening tube 3. Then, the expanding internal thread tube 9 is brought close to the expanding external thread tube 6 and twisted to achieve the threaded engagement of the expanding internal thread tube 9 with the surface of the expanding external thread tube 6. Then, the wide-diameter opening sleeve 12 is covered on the end of the narrow-diameter opening tube 3. The 30-degree oblique groove 13 and the 60-degree oblique groove 14 of the wide-diameter opening sleeve 12 can be inserted into the hole to be drilled, thus realizing the large-diameter hole drilling operation.
