A plastic plate clip comprises a bottom plate, a hook and a torsional spring. The hook comprises rotating shafts provided on two sides of the front end, connecting portions are provided on two sides of the middle part, and a fixed portion is provided at the rear end, the two ends of each of the connecting portions are connected to an end of the respective rotating shaft and one end of the fixed portion, respectively. The bottom plate is a plastic plate, and the front end of the plastic plate arches upward to form an arc-shaped groove into which the other end of the rotating shaft is inserted. The torsional spring is sleeved onto the rotating shaft, and one end of the torsional spring is riveted to the rotating shaft while the other end thereof detachably presses against the bottom plate.

Provided is a binder in which a binder is provided with a binding member having a pressing portion pressing a material to be bound, an operation member operated so as to pivotally rotate to an open state and a hold state, and a base member the binder is further provided with an engagement body, a projection portion caused to engage with the engagement body, and a supporting portion provided with the engagement body, the supporting portion is configured so as to bend toward the projection portion side and bend in a direction of separating from the projection portion and the locked state is formed by engagement between the engagement body and the projection portion.

The present invention relates to a leveling apparatus, methods of using the leveling apparatus, and kits that include the leveling apparatus. The leveling apparatus is useful in various applications, including, without limitation, those applications that involve positioning a planar object (e.g., a wall stencil) against a substantially vertical surface (e.g., a wall) at a desired angle relative to horizontal (e.g., relative to the floor or ceiling).

A clip is provided that is configured to secure an object therein. The clip includes a front portion having a first end, a second end opposite the first end, an inner surface, and an outer surface. The outer surface of the front portion is configured to face away from the object. The base portion has a first end, a second end opposite the first end, an inner surface, and an outer surface. The inner surface of the base portion is configured to face the inner surface of the front portion. The outer surface of the base portion is configured to face away from the outer surface of the front portion. The clip includes a connector coupling the front portion to the base portion such that the front portion is movable in two degrees of freedom relative to the base portion. At least one magnet is coupled to at least one of the front portion and the base portion. The at least one magnet urges the inner surface of the front portion and the inner surface of the base portion together.

A binder clip (1) having an outer surface (5) capable of retaining an applied writing medium (16), such as ink, graphite and the like for use in marking with indicia (17) to identify materials to be held within the binder clip.

This stretch function-added loading sheet is provided with one sheet body and a force crimping unit. The force crimping unit comprises two clamping block plates and one clamping jig, and on one surface of the sheet body, the two clamping block plates are fixed on both sides of a folding centerline on the sheet body. In a state in which the sheet body is folded along the folding centerline such that the two clamping block plates overlap each other with the sheet body on the inside, the clamping jig is fixed to the two clamping block plates so as to clamp the two clamping block plates. The stretch function-added loading sheet has a stretch function with which the sheet body stretches by the clamping jig opening through application of a tensile force perpendicular to the folding centerline to the sheet body, and shrinks when said tensile force is reduced.
