The handle core covering (9) and the outer layer (11) are made of a first material, whereas the soft layer (10) is made of a softer, second material.

The present invention provides a hand-held striking tool that has a head disposed forward of the centerline of a handle. The hand-held striking tool of the present invention may further include a flange positioned beneath the head of the tool, the flange functioning as a second area of contact so that the effect of overstrike may be controlled. The present invention also provides a hand-held striking tool that isolates the striking head of the tool from the handle such that the effect of vibrations caused by using the tool are reduced.

A tensioning device for stretching a threaded bolt by applying tension to the threaded portion of the threaded bolt has a base and a support tube surrounding the threaded bolt and supported on the base. A cylinder housing is arranged as an axial extension on the support tube. A piston is moveably arranged in the cylinder housing and delimits together with an inner wall of the cylinder housing a hydraulic operating chamber. An interchangeable bush is rotatable relative to the piston and can be entrained axially by the piston. The interchangeable bush has an internal thread to establish a screw connection to the threaded portion. A device for path and / or position detection with first and second interacting elements is provided. The first element is fastened to the at least one piston and faces the cylinder housing. The second element is fastened to the cylinder housing and faces the piston.

A toothbrush handle includes a support structure formed of clarified polypropylene and a body formed of thermoplastic elastomer disposed on the support structure. The support structure includes a web having a thickness in a first direction orthogonal to an axis of the toothbrush handle of less than 2 millimeters and at least one rib depending from the web and having a thickness in a second direction, orthogonal to the axis and angled relative to the first direction, of less than about 2 millimeters. The body at least partially covers the web and the at least one rib. The handle has a light transmissivity of greater than 40% through a portion of the handle at which the body covers the web and the at least one rib.

A new tool that connects horizontal bar to vertical bar and disconnects same. V-shaped cut or slots in tip locks in vertical bar opening at a desired angle. Wheel sets on horizontal bar and pushes down to lock into vertical bar. Set tool upside down on bottom of horizontal bar and lift to raise or disconnect horizontal bar from vertical bar.

An annular groove is formed at an open end of a motor case, and a sliding contact projection, which is in an annular plate-shape and corresponding to the annular groove, is formed on a cover. A bottom of the annular groove and the sliding contact projection rotate relative to each other while being in sliding contact with each other to form an annular friction bonded portion therebetween. Wall portions of the annular groove are arranged at such positions as to be concentric with the friction bonded portion. Thus, a storage portion that stores burrs produced at the friction bonded portion is formed. A plurality of protrusions that protrude radially outward is formed on the sliding contact projection over all around. The storage portion is partitioned in the circumferential direction by using the protrusions as partitioning elements.

The invention relates to a portable rescue device (1), for example for portable rescue operations, such as a dilator device, a cutter device or a combination with cutting and dilating functions, having: a housing (2); a first handle (3) and a second handle (4) for a user to actuate the rescue device with both hands; an electric motor disposed in the housing (12); a power supply in the form of a battery (15) or a connection for connecting an external power supply placed on the rescue device (1); a mechanically or hydraulically driven movable piston rod (12) for performing work, in particular expansion work and / or cutting work; a display arranged on the rescue device (1), preferably on the housing (12) thereof; the invention relates to an electronic open-closed loop control device for open-loop and / or closed-loop control of an electric motor (3) and / or a display, in which the rescue device (1) has a communication interface (20) for video data (VD), which is user guidance data, and the display is a video-supported display (8).

The invention provides a bottle cap assembly dislocation auxiliary device which comprises an assembling machine working table and an upper fixed plate, wherein an principle axis is arranged on the working table, a driven wheel is arranged at the lower end of the principle axis and meshed with a driving wheel, a large guide sleeve body, a small guide sleeve body and a tray are arranged on the principle axis, a lower guide sleeve is arranged on the large guide sleeve body, an upper guide sleeve and an internal plastic piece drive plate are arranged on the small guide sleeve body, reciprocating levers are arranged on the upper guide sleeve and the lower guide sleeve, rollers are arranged at the lower ends of the reciprocating levers, cams are arranged at the lower ends of the rollers and fixedly arranged on the working table, the tray is provided with a piece supporting tray and an upper drive plate, a guide seat is arranged on the tray and internally provided with a lifting lever and a thrust bearing, a spring is arranged on the lifting lever, a soft sleeve is arranged at the lower end of the lifting lever, and a steel ball is arranged in a groove at the upper end of the guide seat and contacted with a tooth surface cam plate.
