  • Publication number: 20040050308
    Abstract: A seeding shovel sowing seeds one by one comprises a body, an adjusting rod buckled to a bottom of the body, and an actuating block for actuating the adjusting rod. A center of the shoveling portion has a slotted track for buckling an adjusting rod. A stopping piece is installed at a predetermined position of the shoveling portion. A bottom of the stopping piece has a through hole. Falling seeds may pass through the though hole. The slotted track has a portion coupled to the through hole. The portion is installed with an outlet. An adjusting rod passes through the portion between the handle and the shoveling portion. The top of the distal end of the adjusting rod is installed with an actuating block. Thereby, the actuating block can drive the adjusting rod to move reciprocally. When the user shovels, seeds are embedded into earth rapidly by one hand.

  • Patent number: 6615752
    Abstract: A sowing shovel for sowing seed gradually as the sowing shovel is used. The sowing shovel has a body, an adjusting rod at a bottom of the body, a plate for adjusting the adjusting rod to move reciprocally. The body has a concave shovel portion and a handle. The plate drives the adjusting rod to move forwards and backwards between a handle and a concave shovel portion so that some seeds are placed in the concave shovel portion of the sowing shovel in advance. When the plate is moved to drive the adjusting rod to move backwards, a space is formed for receiving falling seeds. When the user digs soil, seeds can be placed in the soil. Thus the sowing shovel can be operated easily and conveniently only by one hand.

  • Patent number: 5943813
    Abstract: An enclosing mousetrap includes a tubular housing, trap plates at each end, and a hanging hook for connecting the trap plates to the tubular housing. The ends of the tubular housing and the trap plates each contain a pair of holes through which the hanging hooks are engaged to connect the trap plates to the tubular housing. The extended end legs of the hanging hooks clip over cutouts formed in the rim of the tubular housing. The trap plates each have a curved shape and freely swing inward to allow a mouse to have easy access into the interior of the tubular housing. Once inside, however, the mouse cannot exit the tubular housing because the first and second trap plates are disposed such that when the trap plates are pushed outward with respect to the interior of the tubular housing, a lower periphery of the trap plates engages with an inner wall of the tubular housing, which stops the trap plates from swinging outside the tubular housing.
