Scraper

A scraper, comprising:

• a main body, comprising a top shell body and a bottom shell body:
• wherein the top shell body and the bottom shell body are engaged with each other and cooperatively define a receiving cavity with an access opening, and the receiving cavity is configured to store spare blades;
• and
• a cover, comprising a hinge portion pivotably connected to the main body, and rotatable about a hinge axis to close or open the access opening;
• wherein the main body further comprises a shaft reinforcement portion, the shaft reinforcement portion is positioned adjacent to the hinge portion, and the top shell body and the bottom shell body are connected with each other via the shaft reinforcement portion;
• wherein the top shell body and the bottom shell body cooperatively define a mounting cavity with an inlet/outlet, and the mounting cavity extends along a length direction of the main body:
• the shell comprises a first inner wall formed by the top shell body and a second inner wall formed by the bottom shell body;
• wherein the first inner wall and the second inner wall cooperatively form the mounting cavity;
• the main body further comprises a connecting member, the connecting member is slidably mounted in the mounting cavity, the connecting member comprises a mounting portion for mounting a working blade, and the working blade is configured to partially extend out of the mounting cavity or be received in the mounting cavity through the inlet/outlet;
• wherein the main body further comprises a first limiting portion, the first limiting portion is form on the first inner wall, and the connecting member further comprises a second limiting portion matched with the first limiting portion;
• when the connecting member slides from a retracted position to a working position, the second limiting portion is cooperated with the first limiting portion to prevent the connecting member from continuing to slide toward the inlet/outlet, the working blade partially extends out of the mounting cavity through the inlet/outlet, and the scraper is in a working state;
• when a force perpendicular to a sliding direction of the connecting member is applied to at least one of the second limiting portion and the first limiting portion, the second limiting portion is disengaged from the first limiting portion to release the connecting member, and when the connecting member slides to a replacement position, the working blade is in a replaceable state;
• wherein the connecting member further comprises a connection body, the mounting portion is formed at one end of the connection body, the second limiting portion comprises a fixed end and a limiting end, the fixed end is connected to the connection body, and the limiting end is obliquely arranged relative to the connection body and extends toward the inlet/outlet;
• the first limiting portion defines a second limiting recess, and the limiting end is configured to be engaged in the second limiting recess;
• when the connecting member slides to the working position, the limiting end is engaged in the second limiting recess, and directly or indirectly pressing the second limiting portion enables the limiting end to be disengaged from the second limiting recess.
