Abstract: A ratcheting tool includes a handle and a head with a compartment. A drive member includes a first end extended beyond the compartment, a second end extended beyond the compartment, and a gear wheel formed between the first end and the second end. The gear wheel is rotatably mounted in the compartment and includes a toothed outer periphery. A pawl is mounted in the compartment and includes a toothed side facing the gear wheel teeth. The toothed side of the pawl includes a first teeth portion having a first center of curvature and a second teeth portion having a second center of curvature located at a position different from the first center of curvature. A ring is mounted in the compartment and around the first end of the drive member. The ring is operably connected to the pawl such that the ring and the pawl are pivotable about a rotational axis of the gear wheel and that the pawl is movable in a radial direction relative to the ring.

Abstract: A wrench includes a handle and a head extended from the handle. The handle comprises a compartment for rotatably receiving a switch member and a cavity having a first end communicated with the compartment and a second end communicated with a hole of the head. A positioning device cooperates with two positioning grooves in the compartment of the handle for retaining the switch member in one of two positions corresponding to two opposite ratcheting directions of the wrench. A biasing device cooperates with a pawl in the cavity of the handle in response to the position of the switch member to thereby bias the pawl to be selectively engaged with a drive member rotatably received in the hole of the head.

Abstract: A hot melt glue gun including a housing, a heating chamber defined in the housing for heating a solid glue stick to its melting point, a sleeve for holding a portion of the solid glue stick outside the heating chamber, and an insulating member for prohibiting heat transfer from the heating chamber to the sleeve. The insulating member keeps the sleeve at a temperature below the melting point of the solid glue stick, thereby preventing melting of the portion of the solid glue stick outside the heating chamber.

Abstract: A wooden floor board includes a board body and a connector. The board body has two lengthwise ditches formed in the bottom surface. In a preferred form, each lengthwise ditch has a cone-shaped section formed in the innermost section. The elongate connector has two lengthwise upright insert members at two opposite lengthwise sides to engage one of the two lengthwise ditches of two neighborin board bodies. The connector is laid under two neighboring board bodies en assembling the wooden floor boards into a complete floor of a room. Any board body of the complete floor may easily be pried up with a tool like a screwdriver if it is broken and has to be replaced with a new one.

Abstract: A self-illuminating pedal assembly comprises a pedal axle, a pedal rotatably mounted around the pedal axle, a magnet securely mounted to the pedal axle, and a permanent-magnet coil securely mounted to the pedal to rotate therewith. At least one light-emitting diode is mounted to the pedal. The permanent-magnet coil is electrically connected to the light-emitting diode and surrounds the magnet. When pedaling, the permanent-magnet coil is rotated relative to the magnet to thereby generate an alternating magnetic field to cause illumination of the light-emitting diode.

Abstract: A reversible ratchet-type wrench includes a handle and a head extended from the handle. A web defined between the handle and the head includes a cavity communicated with a hole of the head and a receiving hole communicated with the cavity. An inner periphery defining the receiving hole includes a first positioning notch and a second positioning notch. A pawl is mounted in the cavity and includes a first side with teeth for meshing with teeth of a drive member rotatably mounted in the hole of the head. A switch member includes a turn-piece outside the receiving hole of the web for manual operation. The switch member further includes a positioning section extending from the turn-piece and a switching section extending from the positioning section. The positioning section is rotatably received in the receiving hole of the web and has a positioning member retained in one of the first positioning notch and the second positioning notch of the receiving hole of the web.

Abstract: A riding machine (10) includes a battery pack positioned as low as possible in the chassis (12) between the front and rear wheels (14, 15) and removable in a horizontal movement direction while supported by the bottom by a pallet jack. A steering system includes steering shafts (58, 76) which are rotatable together while allowing relative pivotable movement therebetween and which are rotatably connected to the spindle (38) of the steerable rear wheels (15) through a jack shaft (44). In one preferred form, the burnishing head of the machine (10) is raised and lowered relative to the floor surface by an electric actuator (104) which pivots a linkage (92) through a connection allowing floating travel. The pressure which the treating member (16) engages the floor surface is controlled in response to the current level of the electric motor (86) which rotates the treating member (16).

Abstract: A ratchet type ring spanner comprises a handle having a larger cavity for receiving a larger pawl to thereby provide an improved torque-bearing capacity. The pawl is configured to be pressed against a wall defining the cavity of the handle in a manner that the torque is exerted on all of the teeth of the pawl in a more balanced manner to further improve the torque-bearing capacity.

Abstract: A gearbox structure of a beach cycle includes a gearbox which may transmit a power of an engine to a power shaft and a propeller shaft. A clutch mounted between the change gears of the gearbox can be shifted by a gear shift device into a neutral position, a reverse gear position and a forward gear position. The gear shift device includes a gear lever which rotates a sector shaped gear which rotates a gear shift cam shaft which is formed with a slot for driving a gear shift drive fork which shifts the clutch to the neutral position, the reverse gear position, and the forward gear position. The gearbox is further provided with a force increase gear, and the propeller shaft is additionally provided with a drive gear which meshes with a helical gear of a distance calculator which has a connecting line externally connected to an odometer.

Abstract: A head of a wrench comprises a hole having a center and a radius. The head further includes a compartment communicated with the hole. A wall defining the compartment has a center of curvature and a radius of curvature. A ratio between the radius of curvature of the wall and the radius of the hole is equal to or greater than 0.5, but less than 1. A distance between the center of the hole and the center of curvature of the wall is selected to form a deeper compartment to thereby improve the torque-bearing capacity.

Abstract: A tool holder and tools combination includes a base with a head formed on an end thereof. A fixing seat is pivotally mounted to the head and a blade is forcibly inserted into an engaging groove of the fixing seat. A catch is provided to engage with ratchet teeth of the fixing seat to thereby prevent inadvertent folding of the blade. The catch can be retained in a position allowing free pivotal movement of the blade relative to the base.
