In addition, a height of the body 25 of each one of the two supporting feet 24 is larger than a distance between a top surface of the cover 30 and the top surface of the carrier board 10.

(23) The supporting structure 20 is detachably disposed on the bottom surface of the carrier board 10. Molds for the carrier board 10 and the supporting structure 20 can be made separately. With reference to FIGS. 4 and 5, in delivery, multiple carrier boards 10 can be stacked. Multiple supporting structures 20 can be stacked, too. The carrier boards 10 and the supporting structures 20 are stacked separately for decreasing the delivery volume of the pad supporting frame and increasing the space utilization.

(24) With reference to FIGS. 6 to 8, an uncut pad 40 is disposed on the carrier board 10. For cutting, the supporting structure 20 is detached from the carrier board 10. The carrier board 10 is directly disposed on a tabletop 50. The bottom surface of the carrier board 10 completely contacts the tabletop 50. A middle section of the carrier board 10 directly abuts against the tabletop 50. A cutting tool 60 cuts the pad 40 on the carrier board 10 and divides the pad 40 into multiple printing blocks 41. Cutting force applied by the cutting tool 60 is transmitted to the carrier board 10. The carrier board 10 supported by the tabletop 50 cannot be deformed. Each one of the printing blocks 41 is detachably disposed on the carrier board 10 and has at least one printing protrusion 42. The at least one printing protrusion 42 is disposed on a top surface of the corresponding printing block 41. The at least one printing protrusion 42 can show patterns or characters. By customization, the at least one printing protrusion 42 can be disposed on a printing seat of a stamp to be grouped into a printing pad.

(25) With reference to FIG. 10, when the cutting of the pad 40 is finished, the supporting structure 20 can be redisposed on the carrier board 10, and then the cover 30 covers the carrier board 10 for protecting the printing blocks 41 on the carrier board 10. With reference to FIGS. 1 and 10, multiple pad supporting frames covered by the covers 30 can be stacked. The retaining protrusions 23 of an upper pad supporting frame are respectively inserted into the retaining holes 22 of a lower pad supporting frame. The height of the body 25 of each one of the supporting feet 24 is larger than the distance between the top surface of the cover 30 and the top surface of the carrier board 10. After the pad supporting frames are covered by the covers 30, the pad supporting frames can be stacked and cannot be interfered by the covers 30. The printing blocks 41 on each one of the pad supporting frames are protected by the corresponding covers 30.

(26) With reference to FIG. 10, when the cover 30 covers the carrier board 10, the second engaging portions 32 of the cover 30 respectively engage with the first engaging portions 15 of the carrier board 10, and the flanges 14 of the carrier board 10 are respectively inserted into the notches 31.

The flanges 14 are easy to be grabbed by the user for opening the cover 30 conveniently.

(27) Accordingly, the supporting structure 20 is detachably disposed on the carrier board 10. The carrier board 10 and the supporting structure 20 can be stacked separately for decreasing the delivery volume of the pad supporting frame and increasing the utilization of the delivery space. Molds for the carrier board 10 and the supporting structure 20 can be made separately for decreasing the volumes of the molds. The supporting structure 20 is detachably disposed on the carrier board 10. In the cutting operation of the pad 40, the carrier board 10 can be directly disposed on the tabletop 50. The cutting force is applied on the carrier board 10, the carrier board 10 will not be deformed, and the top surface of the carrier board 10 keeps flat for improving the cutting quality of the pad.

(28) In addition, the height of the body 25 of each one of the supporting feet 24 is larger than the distance between the top surface of the cover 30 and the top surface of the carrier top 10. Thus, the pad supporting frames covered by the covers 30 can be stacked for increasing the fully-protective effect of the pad supporting frame. Furthermore, the flanges 14 of the carrier board 10 are inserted into the notches 31 of the cover 30 and exposed out of the two opposite side plates for increasing the opening convenience of the cover 30.
