Abstract: A scraper includes a main body and a cover. The main body includes a top shell body and a bottom shell body. The top shell body and the bottom shell body are engaged with each other and cooperatively define a receiving cavity with an access opening. The receiving cavity is configured to store spare blades. The cover is hinged to the main body, and rotatable about a hinge axis between the cover and the main body to close or open the access opening. The main body further includes a shaft reinforcement portion, the shaft reinforcement portion is arranged close to a hinge position between the cover and the main body, and the top shell body and the bottom shell body are connected with each other via the shaft reinforcement portion.

Abstract: A scraper includes: a blade; a housing; and a connection member. The housing defines a storage cavity and has a first limiting portion. The connection member is slidably mounted in the storage cavity and includes an external portion in which the blade is mounted and a second limiting portion mated. When the connection member is slid from a first position to a second position, the second limiting portion is mated with the first limiting portion to prevent sliding of the connection member, the blade partially protrudes out of the storage cavity. When a force perpendicular to a sliding direction of the connection member is applied to the second limiting portion or the first limiting portion, the second limiting portion is disengaged from the first limiting portion to release the connection member; when the connection member is slid to a third position, the blade is in a replaceable state.

Abstract: A scraper includes: a housing, configured to enable an operating blade to be mounted thereon; a box body, defining a storage cavity to store at least one spare blade, where the storage cavity has an opening; at least one magnetic member, arranged on the housing and/or the box body. The at least one magnetic member is configured to apply a magnetic adsorption force on the at least one spare blade to fix the at least one spare blade in the storage cavity to prevent the at least one spare blade from detaching off from the opening.
