    摘要： A pulling tool for pulling nails, screws, rivets, pegs, or other protrusions includes a jaw which may be opened to receive the head of the protrusion. The jaw is then at least partially closed against the protrusion, and when the handle of the tool is pulled, the jaw is both urged shut and also away from the surface from which the protrusion extends. Thus, as the protrusion is pulled, its shaft is also more tightly grasped, which helps to pull the protrusion from the surface without stripping off its head/cap. The pulling tool can be provided as a part of a hammer, crowbar, or other conventional tool.

    摘要翻译： 用于拉动指甲，螺钉，铆钉，钉或其他突起的牵引工具包括可以打开以接收突起的头部的颚。 然后，所述钳口至少部分地相对于所述突起封闭，并且当所述工具的手柄被拉动时，所述钳口被关闭并且也远离所述突起延伸的表面。 因此，当拉伸突起时，其轴也被更加紧密地抓住，这有助于从表面拉动突起而不剥离其头/帽。 牵引工具可以作为锤，撬棍或其他常规工具的一部分提供。

    摘要： A tool for performing lopping, pruning and similar operations includes a tool support, a tool head, an actuating line and an actuating handle. The tool support preferably includes a pair of telescoping tubes and the tool head includes a blade movable to perform cutting operations. The blade is coupled to the actuating line and remotely movable by tensioning the actuating line. The actuating line passes through a portion of the tool support to the actuating handle. The actuating handle includes a line engagement mechanism or clutch assembly that engages and holds the line when the actuating handle is slid on the tool support. The tool is actuated by a first movement of the actuating handle that causes the engagement mechanism to engage the actuating line, followed by a second movement that tensions the line to move the blade. A reel mechanism below the engagement mechanism collects the actuating line when the tool support is retracted and dispenses line when the tool support is extended.

    摘要： A device for removing weeds from the ground comprises an elongated shaft, a handle mounted to an upper end of the shaft, a pair of blades mounted for opposed pivotal movement at a lower end of the shaft, and a plunger. Each blade has an upper section located above a pivot point of the blade and a lower section located below the pivot point. The plunger is mounted for reciprocal sliding movement between an extended position intermediate the lower sections of the blades and a retracted position intermediate the upper sections of the blades. The plunger and the upper sections of the blades include cam surfaces configured such that movement of the plunger from the extended position to the retracted position forces the upper sections of the blades away from one another, whereby tips of the blades are forced to converge towards one another to capture the weed and accompanying root structure. The weed and surrounding soil plug can be released by squeezing a hand-lever.

    摘要： A punch tool for use by children is disclosed. The punch tool includes a removable die and punch assembly that can be inserted and removed from a base portion to permit the punching of holes having a variety of configurations. A cap is rigidly secured to the base and has an indented portion so sheets of paper can be inserted between the base and the cap. The retainer cap includes an opening in which an actuator button is slidably mounted and against which the punch is biased by a spring. Thus, a user can slide a sheet of paper between the base and the retainer cap and punch a hole therethrough by pressing the actuator button with sufficient force to overcome the spring bias.

    摘要： The invention is directed to storage containers and lids for storage containers which provide for a secure closure and a storage container which is airtight and leakproof. The lid includes a generally U-shaped closure made of a plastic material for securing to a container base; a center window also made of a plastic material and preferably the same as the U-shaped closure; and a thermoplastic material which provides for a sealing gasket on the underside of the U-shaped closure for mating with the container base and a perimeter seal on the outside of the U-shaped closure and around the outer circumference of the center window. The lid may further include a gripping tab made at least in part of thermoplastic material in the lid corner for opening or closing the container, and wings made of a thermoplastic material in one or more portions or corners of the lid.
