Abstract: A scraper includes a first clamping member, a second clamping member, and a locking device. The first clamping member has a first clamping portion and a first connecting portion. The second clamping member has a second clamping portion and a second connecting portion connected with the first connecting portion. The locking device includes a pivoting shaft connected with the first and second pivoting portions, and a switching button disposed on the second clamping member and connected with the pivoting shaft. The switching button is relatively rotatable between a locking position and a releasing position with the pivoting shaft as the center with an angle of less than 180 degrees to cause the second clamping portion to approach or move away from the first clamping portion.

Abstract: A scraping tool includes a first holding member having a first through-groove between a first holding portion and a first connecting portion. A second holding member includes a second through-groove between a second holding portion and a second connecting portion. The second connecting portion is connected to the first connecting portion to permit the second holding member to sway relative to the first holding member between a holding position and an extended position. A locking device includes first and second abutting portion respectively abutting against the first and second holding member and a sliding portion slideably extending through the first and second through-groove. The locking device is movable relative to the first and second holding member between a locking position in which the second holding member is in the holding position and a release position in which the second holding member is movable to the extended position.

Abstract: A utility knife includes a shell including first and second shell bodies releasably assembled together. A compartment is defined by the first and second shell bodies. A channel is defined at a distal end of the first shell body of the shell and is disposed outside of the compartment. A blade carrier assembly releasably engages with a blade and includes a seat movably received by compartment of the shell. The blade carrier assembly is operably movable to a first position in which the blade is in a retracted position and not extending out of the shell and, to a second position in which the blade is in an exposed position and extending out of the shell. The blade carrier assembly in the second position thereof is also guided by the channel.

Abstract: A scraper includes a shell, a first controlling mechanism moveably installed within the shell for carrying a razor. The first controlling mechanism is moveable between a first position that the razor is exposed outside the shell and a second position that the razor is concealed in the shell. The scraper also includes a second controlling mechanism being independent of the first controlling mechanism and being utilized to selectively lock the razor therein. The razor is adapted to be removed from the first controlling mechanism when the second controlling mechanism is in an unlocked position. In addition, the scraper includes a compartment defined in the shell for storing unused razor(s).
