A roller frame device that is adapted to hold a paint roller in one or more positions, at least one of which is in an approximately vertical orientation.

An angle adjustable connecting part for farm equipment and hand tools easily detaches from a working part of farm equipment and a hand tool from a sack. A connecting part is formed on the front end of a working part of farm equipment or hand tool. A connecting part is also formed on the front end of a sack, thereby coupling the working part and the sack. The connecting part has a fixing hole formed in the center thereof, and multiple angle adjusting holes are formed concentrically outward. A fixing hole is formed at the center outward from the connecting part. A fixing plate has a fixing protrusion inserted into the angle adjusting hole. When a fixing screw is fixed to the fixing plate and the fixing hole of the connecting part, the fixing protrusion of the fixing plate is fixed to an angle adjusting hole of the connecting part.

Embodiments of the present disclosure generally relate to a pivoting assembly, to tools including the pivoting assembly, and to their methods of use in, e.g., collecting lunar samples. One embodiment comprises a shaft coupled to a handle at one end and coupled to a pivoting assembly at the opposite end. The pivoting assembly may comprise a slotted axle, a locking rod having a head engageable with a slot of the slotted axle, and a release handle coupled to the locking rod. The release handle is movable to move the head of the locking rod into a locked position and an unlocked position. A rotatable arm is coupled to the pivoting assembly and is rotatable relative to the handle when the head of the locking rod is in the unlocked position.

The pivot shaft structure moving around virtual axis includes an assembly of a main body, a first operation board and a second operation board disposed on the main body. The first operation board has an arm section. The second operation board has an arm section. The arm sections of the first and second operation boards are respectively received in a first arched rail and a second arched rail of the main body. The first and second arched rails are arched and disposed around a virtual axis. When a user operates the first operation board or the second operation board to move, the first operation board or the arm section thereof and the second operation board or the arm section thereof respectively synchronously move around the virtual axis along the first and second arched rails toward each other to achieve opening/closing effect.

The present disclosure relates generally to an arthropod trapping device, more particularly, to a compact and portable trapping device comprising a housing and an insert, where the insert is also attachable to or insertable into a handheld trapping implement.

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.

The present embodiments provide a handheld device for transferring a substance. In example embodiments, a handheld device for transferring a substance includes a receptacle configured to receive and hold the substance. The receptacle is pivotably mounted to a handle about at least one pivot point, thereby forming an axis of rotation of the receptacle. The receptacle is rotatable about the axis of rotation in response to an external force being applied to an outer surface of the receptacle.
