[0040] Example

[0041] like Figure 1-2 As shown, the present invention provides a hole punch 1 cover plate 2, the cover plate 2 being detachably connected to the hole punch 1, so that the cover plate 2 can be carried with the hole punch 1, making it readily available when punching holes. The detachable connection makes it easy to take out, and when not in use, the cover plate 2 is combined with the hole punch 1.

[0042] When needed, such as Figure 2 As shown, the cover plate 2 is removed from the punch 1. That is, when the cover plate 2 is separated from the punch 1, the cover plate 2 is placed on the side of the workpiece to be punched away from the punch 1. The cover plate 2 is then removed and placed under the workpiece at the position where a hole needs to be punched. Specifically, at least one side of the cover plate 2 forms an abutment surface 4 that contacts the cutter head of the punch 1. This abutment surface 4 needs to be wear-resistant, smooth, and flat, so as to achieve the effect of being consistent with the surface of a specific pad.

[0043] By detachably installing a cover plate 2 on the punch 1, the cover plate 2 is connected to the punch 1 when not in use, reducing the space occupied and making it easy to carry. When drilling is needed, the cover plate 2 is removed and placed under the part to be drilled. At this time, the cover plate 2 is used as a gasket, which optimizes the experience, makes it easier for users to improve work efficiency, and the drilling operation does not need to be in a specific location.

[0044] Specifically, a storage area 3 is formed at the end of the punch 1 located in the non-grip area. The cover plate 2 is detachably fitted into the storage area 3. The punch 1 is cylindrical, and the grip area is located on the outer side of the cylindrical shape. The storage area 3 is located at the tail end of the punch 1 away from the punching head. This location does not affect the normal use of the punch 1. The cover plate 2 is fitted and stored at the upper end of the punch 1, separate from the area that needs to be gripped when punching, so that the setting of the cover plate 2 will not affect the use of the punch 1 when gripping it.

[0045] To ensure the cover plate 2 is sturdy and durable, a hard pad 5 is provided on the cover plate 2 for contacting the part to be drilled. The surface of the hard pad 5 is the contact surface 4 that contacts the cutting head. The pad 5 can be made of hard plastic or hard metal, etc., and is fixed on the cover plate 2 according to actual needs. The hard pad 5 provided on the cover plate 2 can contact the cutting head when drilling, avoiding damage to the cover plate 2 and the table below by the cutting head. It plays the same role as a specific pad, and the cover plate 2 is more flexible and convenient to use.

[0046] Specifically, the pad 5 is higher than the surface of the cover plate 2, and the pad 5 and the cover plate 2 form a stepped structure that matches and is embedded in the storage area 3. Correspondingly, the storage area 3 is recessed at the end of the punch 1. The pad 5, which is higher than the surface of the cover plate 2, is matched and embedded in the storage area 3, so that the cover plate 2 can be matched and stored in the storage area 3.

[0047] To ensure the stability of the connection between the cover plate 2 and the punch 1, the cover plate 2 is provided with a snap-fit ​​part 6, and the storage area 3 is formed with a snap-fit ​​groove that matches the snap-fit ​​part 6. The snap-fit ​​groove cooperates with the snap-fit ​​part 6 to fix the cover plate 2 in the storage area 3.

[0048] Specifically, the snap-fit ​​part 6 can be a snap-fit ​​protrusion protruding on the cover plate 2, and the snap-fit ​​groove is correspondingly provided in the storage area 3. When the cover plate 2 is matched and closed on the storage area 3, the snap-fit ​​protrusion and the snap-fit ​​groove snap-fit ​​and correspond to each other, so as to play a fixing role.

[0049] Meanwhile, the snap-fit ​​part 6 can also be configured as a spiral protrusion, and the snap-fit ​​groove is correspondingly formed as a spiral snap-fit ​​groove. That is, an external thread is provided on the outer periphery of the stepped structure on the cover plate 2, and an internal thread matching the external thread is provided on the inner wall of the storage area 3. The cover plate 2 is fixed in the storage area 3 by rotating and tightening, so as to prevent the cover plate 2 from falling off and ensure the stability of the cover plate 2.

[0050] On the other hand, the cover plate 2 and the punch 1 can also be fixed by providing a first magnetic element in the cover plate 2 and a second magnetic element that attracts the first magnetic element in the storage area 3, so as to attract and fix the cover plate 2 in the storage area 3. The two magnetic elements are not shown in the figure. The cover plate 2 can be fixed to the end of the punch 1 relatively quickly and conveniently by magnetic attraction, making it easier to take out.

[0051] like Figure 3As shown, in order to expand and improve the storage capacity of the storage area 3, a receiving cavity 7 is formed in the recess of the storage area 3. The cover plate 2 is matched and covered on the opening of the receiving cavity 7. A certain gap is formed between the bottom of the receiving cavity 7 and the cover plate 2 matched and covered on the opening, so as to ensure that the internal space is sufficient to accommodate the punch head 1. In this way, the space is reused, and the punch head 1 can be better accommodated, making full use of the space. At the same time, the cover plate 2 can close the opening of the receiving cavity 7 to prevent the punch head from falling out.

[0052] Furthermore, the accommodating cavity 7 is provided with a plurality of placement holes 8 for matching and accommodating different sized cutting heads. The placement holes 8 can be opened at the bottom of the accommodating cavity 7, or an additional filling block 9 with placement holes 8 suitable for the accommodating cavity 7 can be placed in the accommodating cavity 7. The filling block 9 can be made of perforated sponge or the like. The filling block 9 is fixed in the accommodating cavity 7 to ensure that the cutting heads of different sizes are limited in the placement holes 8, remain stable and do not shake, and ensure that the height of the cutting head is accommodated in the accommodating cavity 7. By providing multiple placement holes 8 of different sizes in the accommodating cavity 7, multiple cutting heads of different sizes can be carried, and the cutting heads are matched and embedded and are not easy to fall off.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
