A self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least one pair of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.

A grafting device including a rootstock holding unit and a scion holding unit both provided in a main body and relatively movable in a predetermined direction, at least one of the rootstock holding unit and the scion holding unit includes: a hand module including: a grip portion configured to be openable and closable for gripping a stem of a plant; reciprocating portions an operating rod and a slide plate provided between the grip portion and the main body and capable of reciprocating; a motion converting portion configured to convert reciprocation of the reciprocating portion into an opening/closing motion of the grip portion; and a biasing means configured to bias the reciprocating portion in any one direction of the reciprocating movement; and a drive means provided in the main body and configured to drive the reciprocating portion in a direction opposite to a biasing direction by the biasing means.

A clamp includes a fixed portion on which a medical tube is placed, a movable portion that is provided above the fixed portion to face the fixed portion, and a closing portion that presses and closes the medical tube when the movable portion is pressed toward the fixed portion. The closing portion includes a presser that protrudes from the movable portion toward the fixed portion and presses the medical tube, a pair of sidewalls that extends, like a wall, from both sides of the fixed portion and prevents the medical tube from being shifted laterally, and a guide structure that allows the presser to be guided between the sidewalls.

A cable protector clamp assembly that includes a clamp body configured to hold and align a cable along a pipe, the clamp body including a cable holder; and a stop collar configured to fix a position of the clamp body adjacent to a radially protruding element around the pipe and to prevent the clamp body from rotating around the pipe.

A system for retaining a folded proprotor blade in flight. The system includes a rotary actuator mechanism operable to generate torque via a shaft that rotates about an axis generally parallel to a chordwise direction of the folded proprotor blade, a pair of clamping arms movable in a direction generally parallel to a beamwise direction of the folded proprotor blade, a pair of linkage arms interoperably responsive to the rotary actuator mechanism and coupled between the rotary actuator mechanism and the pair of clamping arms, and a first guide rod extending between the pair of clamping arms in the direction generally parallel to the beamwise direction.
