  • Patent number: 6840376
    Abstract: A tool box includes a left cover and a right cover which are pivotably connected on the left sidewall and the right sidewall respectively. The left cover, the right cover, the left sidewall and the right sidewall each have grooves defined in an inside thereof so that a first layer and a second layer connected by two rods are movably received between the left cover, the right cover, the left sidewall and the right sidewall by engaging protrusions on the first layer and the second layer in the grooves. The grooves each have two recesses defined in an inside thereof so that the protrusions can be shifted into the recesses to set the first layer and the second layer in position. Casters are connected to an under side of the tool box and allow the tool box to be moved in a convenient way.

  • Patent number: 6711825
    Abstract: A hacksaw includes a U-shaped frame and a handle connected to a first end of the frame and an engaging port is connected to a second end of the frame. A groove is defined longitudinally in the handle and a passage is defined in the handle. The passage intersects the groove and communicates with the groove. A retaining member is movably received in the passage and a recess defined in the retaining member so that a blade extends through the groove and the recess. The blade is engaged with the engaging port. A cam member is pivotably connected an end of the retaining member such that the retaining member is lifted to secure the blade between an inside of the recess and the inside of the groove by pivoting the cam member. The blade is easily loosened by pivoting the cam member in the other direction.
