A variable valve device of the invention has a structure in which, as connecting means for connecting a movable cam 22 located in an outer periphery of an outer camshaft 17a and an inner camshaft 17b located inside the outer camshaft 17a, there are provided a pin-like member 24 that is movably inserted so as to penetrate the movable cam 22, the outer camshaft 17a and the inner camshaft 17b along a diametrical direction of a shaft member 17 that is formed by turnably encasing the inner camshaft 17b in the outer camshaft 17a, and an escape-preventing portion 50 disposed in the end portion of the pin-like member 24. The movable cam 22 and the inner camshaft 17b are thus connected together while preventing large press-fit load and axial force from acting on components.

The invention relates to a full-automatic lock for container securing and belongs to the technical field of container securing and locking. The full-automatic lock is characterized in that a lock head is formed by embedding a cone in a middle notch of a hook; a longitudinal section of the hook is connected with a hook head body through a thick hook shaft, the hook head body is in the shape of an approximate equilateral triangle with a fillet, the hook head body is connected with the thick hook shaft at the position approximately two thirds of the side length, a hook head and an X-direction self-locking surface are formed by the reserved part of one third of the side length, an outward protrusion in the shape of an obtuse triangle is arranged at the back of the hook shaft, and holes allowing a load-bearing pin shaft to penetrate are formed in the end portions of the hook shaft. The cone is of an upper bird head-lower bird head structure, an upper bird head is broad in mouth and large in eyes, a lower bird head is small in eyes and sharp in mouth, the upper bird head and the lower bird head share a rectangular tail parallel to the bottom surface, a groove capable of allowing a limit block to be inserted in is formed in the back of each bird head, and a return spring is arranged. The full-automatic lock has the advantages that leftward-rightward or frontward-backward movement of a container is prevented; the container is prevented from rolling over; the full-automatic lock is quite convenient to mount and use; besides, the full-automatic lock is simple in structure and low in cost, and can be widely applied to vehicle-mounted and ship containers.

The invention discloses a mowing table transmission device of a pedestrian-controlled lawn mower. The mowing table transmission device comprises a flat belt, an engine belt pulley, two cutter belt pulleys and a tensioning wheel mechanism, wherein a mechanism for preventing the flat belt from falling out of grooves is arranged on the outer side of the flat belt between the engine belt pulley and the other cutter belt pulley, and belt blocking hoods are respectively arranged on the outer sides of the two cutter belt pulleys; the upper and lower sides of the flat belt are located between the upper and lower horizontal rods of a belt support rack; the groove width of the engine belt pulley is larger than the width of the flat belt. The mowing table transmission device has the advantages that the device is simple in structure, low in cost and high in use efficiency; when the terrain clearance of a mowing table is adjusted, the flat belt can move vertically to adapt to the height change of the mowing table, and the service life of the flat belt is prolonged; the mechanism for preventing the flat belt from falling out of the grooves uses the belt support rack to prevent the flat belt from falling out of the grooves and can drive the flat belt to move up and down so as to adjust the terrain clearance of the mowing table.
