Scraper

A scraper, comprising:

• a blade;
• a housing, defining a storage cavity therein, wherein the storage cavity has an opening, and a guiding hole is defined in the housing;
• a connection member slidably mounted in the storage cavity, wherein the connection member comprises an external portion in which the blade is mounted and an operation button exposed from the guiding hole;
• the guiding hole extends along a sliding direction of the connection member, the operation button is slidable along a length direction of the guiding hole so as to drive the connection member to move;
• and the blade is configured to switch among a storage state, an operating state, and a replaceable state;
• a limiting member, comprising a first limiting portion and a second limiting portion, wherein when the blade is in the operating state, the first limiting portion and the second limiting portion are mated with each other to limit the connection member and prevent the blade from disengaging from the operating state;
• wherein, when the first limiting portion and the second limiting portion relatively move to disengage from each other, the connection member is released, and the blade switches to the replaceable state;
• wherein one of the first limiting portion and the second limiting portion is located on the housing, and the other of the first limiting portion and the second limiting portion is located on the connection member;
• wherein the connection member is movable between a first position and a second position, when the connection member moves from the first position to the second position, the first limiting portion and the second limiting portion are mated with each other to prevent the connection member from continuing sliding towards the opening;
• and
• wherein the connection member comprises a body portion;
• the external portion is positioned at one end of the body portion;
• the second limiting portion comprises a limiting button and a first resilient portion connected to the limiting button;
• when the connection member is slid to the second position, the limiting button abuts, by a resilient force of the first resilient portion, against the first limiting portion;
• the first resilient portion is compressed, when the limiting button is pressed, to stop abutting against the first limiting portion.
