In a connector, a first connector element, in particular a plug, and a second connector element, in particular a socket or a housing adapter, have a first or second contact insets around the first contact inset of a plug, and a sleeve-shaped latch segment is arranged from which, running along the longitudinal direction of the connector, resilient latch flanges with latch tabs are formed that are appropriate for locking onto a ring-shaped groove formed on the inner side of the second connector el...

A circular cutter comprises a circular blade mounted to a front end of a handle via a shaft assembly, in the handle is disposed a slide member for controlling a hood having a T-shaped hole, the T-shaped hole is located correspondingly to a center of the circular blade and arranged outside of the shaft assembly, when the hood draws back under the control of the slide member, a surface of an object to be cut will press against the hood, so as to make the shaft assembly deviate left or right freely...

A circular saw includes a worktable, a mounting seat extending upwardly from the worktable for mounting a motor thereon, a blade supporting unit pivotally mounted on the mounting seat at a pivot end so that an opposite free end is turnable to be close to and away from the worktable, and a saw blade shaft mounted rotatably on the blade supporting unit about a blade axis parallel to an output shaft axis of an output shaft of the motor and having a saw blade mounted thereon. The saw blade shaft is ...

A circular saw includes a base member abutting a supporting surface and an operating arm pivotally mounted to the base member. A gearbox is formed on a free end of the operating arm. The gearbox includes a first cavity and a second cavity respectively laterally defined in two opposite side of the gearbox. A hole is laterally defined in a bottom of the first cavity and communicates with the second cavity. A handle extends from the gearbox for user to easily operate the circular saw. A motor is la...

A circular saw includes a table having an upper surface for placing a workpiece thereon. A saw unit has a saw blade mounted thereon and is supported on the table such that the saw unit is movable in a horizontal direction parallel to the upper surface of the table and is movable in a vertical direction perpendicular to the upper surface of the table. At least one of a first lock device and a second lock device is provided. The first lock device is operable to prevent the saw unit from moving in ...

A circular cutter comprising a circular blade mounted to a front end of a handle via a shaft assembly, in the handle is disposed a slide member for controlling a hood, the hood is formed with a T-shaped hole located correspondingly to a center of the circular blade and is defined with an arc gap located in a cutting direction of the circular cutter, the T-shaped hole is arranged at both sides of the circular blade and located outside of the shaft assembly, when the hood draws back under the cont...

The present invention relates to an apparatus that forms a polymeric structure. The apparatus has a mold plate, a circular trench, a male and female interconnect, a vertical gap filler, and a cylinder. The mold plate has a predetermined geometric design. The circular trench is in the mold plate and the difference between the outer diameter and the inner diameter of the circular trench is a distance D. The male interconnect and the female interconnect are interspaced between each other. Each inte...

A subdivision system providing alternating one-way traffic on all subdivision streets, said system comprising, a plurality of traffic circles, each traffic circle having a traffic lane surrounding the traffic circle, a plurality of development circles, each development circle containing one or more buildings, each development circle having an inner parking lane, and an outer traffic lane, surrounding the development circle, the rotational direction of traffic flow around a traffic circle being o...

A side cutting edge of a tip 20 fixed to the outer circumference of a circular saw blade body 11 has a inflexion point K at a portion at which the tip projects laterally to the greatest distance. An outer-circumferential-side portion of the side cutting edge has a negative radial clearance angle of not less than -1.degree. but less than 0.degree. at the inflexion point, and an inner-circumferential-side portion of the side cutting edge has a positive radial clearance angle of greater than 0.degr...

A circular saw 30 includes a housing 32, a fixed upper guard 34, a movable lower guard 36 and a shoe 38. A saw motor 48 is selectively operated to rotate a circular saw blade 54 to facilitate the formation of a selective cut or kerf into a workpiece 57 under the control of an operator. A forward end 126, and a wing wall 138, of the upper guard 34 form an enclosed chamber 122 which is placed in close proximity with an adjacent surface 46 of the shoe 38 to essentially preclude chips from dischargi...
