Abstract

A stamp comprises a stamp assembly (1) with a cutting tool (2) mounted inside. A tool seat (30) of the cutting tool (2) has an inclined blade recess (3012), where a moving element (32) and a blade (31), connected together, are mounted in. An operating element (34) is mounted in the tool seat (30) and combined with a resilient unit (33), connectting to the moving element (32). When disposed at an idle or extending-out position (3022, 3023) of the tool seat (30), the operating element (34) is fixed by the resilient unit (33) while the blade (31) is fixed through the moving element (32). When forced, the operating element (34) detaches from the tool seat (30) to be moved, and the blade (31) is driven by the moving element (32) to extend out of or retreat back to the tool seat (30).

Description

1. Field of the Invention The present invention relates to a stamp, especially to a stamp having functions of cutting to unpack and roll-printing garbled characters to protect personal identity information. 2. Description of Related Art Nowadays, online shopping, home shipping, etc. provide people with convenient ways to do shopping. Because online shopping and home shipping deliver goods through packages and packing boxes, recipient's personal information must be marked on the packages or the packing boxes for logistics and distribution, and for confirmation of the recipient's identity. After the recipient receives the package, as their personal information is shown on the package, the recipient usually needs to remove the information before throwing away the package for protecting their personal information. To remove the personal information, the recipient uses dark-color markers to cover the information or peels off stickers with the information from the package. However, this is inconvenient. So, there are protection roller stamps on the market that can roll and print garbled characters. The recipient uses the protection roller stamps to stamp dark-color garbled-characters patterns on the stickers to cover personal information, so that the package will no longer reveal their personal information. In addition, the protection roller stamp nowadays further has a foldable cutting tool to facilitate unpacking. However, the foldable cutting tool of the roller stamp is inconvenient in use, thus needing to be improved. The main objective of the present invention is to provide a stamp having a cutting tool to resolve drawbacks that a foldable cutting tool of a conventional roller stamp is inconvenient in use. The stamp comprises a stamp assembly and the cutting tool. The stamp assembly comprises a main body and a bottom cover detachably mounted at a bottom portion of the main body. The main body comprises an assembling opening disposed at a top portion of the main body. The cutting tool is mounted at the main body and comprises a tool seat, a blade, a moving element, a resilient unit, and an operating element. The tool seat is mounted at the assembling opening of the main body and comprises a moving chamber and an inclined blade recess. The inclined blade recess communicates with the moving chamber, is disposed at a side of the moving chamber, is inclinedly elongated to a top portion of the tool seat, and forms a blade entrance at the top portion of the tool seat. The tool seat comprises a horizontal elongated hole disposed at the top portion of the tool seat, communicating with the moving chamber, and defined to have an idle position and an extending-out position located horizontally apart from each other. The extending-out position is disposed at an end, adjacent to the blade entrance, of the horizontal elongated hole. The blade entrance and the horizontal elongated hole are exposed outside of the main body. The blade is mounted in the inclined blade recess of the tool seat and can be operated to be pushed inclinedly and upwardly out of the blade entrance along the inclined blade recess and to be pushed backwardly into the inclined blade recess. The moving element is mounted inside the tool seat, is connected to the blade, and can be moved inside the moving chamber of the tool seat to drive the blade moving along the inclined blade recess. The resilient unit is mounted inside the moving element. The operating element passes through the horizontal elongated hole of the top portion of the tool seat and is mounted through the moving element. The resilient unit applies a resilient force to the operating element, such that when the operating element is disposed at the idle position or the extending-out position of the tool seat, the operating element is buckled and limited in position in the tool seat by the resilient force from the resilient unit. A position of the blade is fixed by the moving element. The operating element is detachable from the tool seat when under an external force. When the operating element is under the external force to be detached from the tool seat, the operating element is movable along the horizontal elongated hole, and the blade is driven by the moving element to extend out from or retreat backwardly to the tool seat through the blade entrance of the tool seat. In the stamp, the operating element is mounted through the horizontal elongated hole of the tool seat of the cutting tool mounted in the main body. The operating element combines the resilient unit to be connected to the moving element in the tool seat while the moving element movably connects the blade, thereby combining elements in the stamp. When the operating element is disposed at the idle position or the extending-out position of the tool seat, the resilient force of the resilient unit buckles and limits the operating element in position in the tool seat, and the moving element limits the blade in position, thereby ensurin
