Embodiments are described for a simple convertible utility knife and scraper includes a handle, slide mechanism, and flat spring with a centrally mounted utility blade. The flat spring locks into precut positions in the handle to secure the blade in the desired position, whether in a cutting position or a scraping position. The blade can be partially extended to expose the front of the blade in the cutting position. When the slide is fully extended, the blade can rotate about a central axis to a position perpendicular to the handle and then be retracted into slots at the end of the handle to secure and support the blade in the scraper position.

A prying head is provided in the present disclosure. The prying head, which is used in cooperation with a hand tool, includes a prying portion, a supporting portion and an assembling portion. The prying portion includes a ground-abutting surface and an article-abutting surface. The article-abutting surface is connected to the ground-abutting surface to form a sharp edge. The supporting portion is connected to the prying portion and includes a curved surface. The curved surface is connected to the ground-abutting surface and the article-abutting surface, so as to make an end of the supporting portion away from the sharp edge into a curved form. The assembling portion is connected to the supporting portion and includes a blind hole. The blind hole is recessed from an end of the assembling portion away from the sharp edge.

Disclosed is a tool bar. The tool bar comprises a head part, a tail part, a pipe connection assembly, a backstop mechanism and a bushing member. The head part and the tail part are connected with each other by the pipe connection assembly. The bushing comprises a cone section and a cylinder section; one end of the head part passes through the cylinder section and connected to an inner thread of the cone section; the outer side of the cone section is configured to secure with a tool head; an external thread is provided on an outer surface of the cylinder section. The backstop mechanism comprises an intermediate member and a lock cap; the intermediate member is a hollow cylinder.

A handheld implement with a replaceable work tool includes a handle body which is equipped with a locking device for detachably mounting the work tool. The locking device includes a movable member, at least one retaining member and a first spring. The first spring abuts against the retaining member so that the retaining member is inserted into a locking hole of the work tool while remaining in an extended state. The retaining member includes a first mating body including at least one second mating body. The second mating body includes a mating portion, and the movable member performs translational movement so that the mating portion and the first mating body cooperate with each other to drive the retaining member to retreat and then withdraw from the locking hole of the work tool.

A scraper apparatus, comprising a scraper blade; a scraper blade holder; wherein the scraper blade and the scraper blade holder are rotatable relative to one another about a pivot connection formable by the scraper blade and the scraper blade holder; wherein the scraper blade has at least one scraper blade fastener; wherein the scraper blade holder has at least one scraper blade holder fastener; and wherein the at least one scraper blade fastener is fastenable with the at least one scraper blade holder fastener via the scraper blade and/or the scraper blade holder being rotated about the pivot connection.
