A stamping tool has a stamping punch for forming at least one punched hole in a workpiece. The stamping punch is guided in a guide housing along a stamping displacement movement. The stamping punch has a stamping element and a head element, which is connected with the stamping element by means of a screw connection. A length of the stamping punch between a head front face and a stamping surface, which closes off the stamping element at the front, can be set by means of the screw-in depth of the screw connection. An unlocking body, which is freely accessible from outside of the guide housing can be displaced between a locked position, in which the screw connection is blocked, and a screwing position, in which the screw connection is released. The result is a stamping tool with a simplified length adjustment.

The invention discloses a method for rapidly positioning and installing hanging bars, wherein perpendicular corresponding points of drilling points designed on a ceiling are marked on the ground; a mobile precise-positioning hanging bar drilling device is used for not only positioning the drilling points on the ceiling through the perpendicular corresponding points, but also drilling; and a convenient hanging bar installer is used for installing the hanging bars in eye holes at the drilling points. The method for rapidly positioning and installing the hanging bars has the beneficial effects of simple structure and rational design, known according to the descriptions of the scheme. Operations such as positioning, drilling and installation are performed by operators on the ground, so that the potential safety hazards are reduced. The operators can drill the ceiling and install the hanging bars on the ceiling even on the ground, without standing on a herringbone ladder; since the operators do not need to move, adjust or climb the herringbone ladder, the working efficiency is increased. Furthermore, the operators do not work in high-places resulting in operation inconvenience, so that the working quality is improved.

A filter assembly includes a reusable filter frame and a replaceable, pleated, reversibly expandable, self-spacing filter removably arranged in the frame. The self-spacing pleated filter expands uniformly with equal pleat spacing to allow the filter to be easily installed in the reusable filter frame without the aid of a secondary spacing structure. When the filter is expanded to the length of the filter frame, the filter is under tension, thereby allowing the length of the filter to be readily adjusted to match the length of the frame and allowing the pleats to be aligned with corresponding ribs provided in the frame.

The invention relates to a traveling wave distance measurement device based on a passive magnetooptic glass current transformer principle. A small voltage signal reflecting primary side current amplitude of a transmission line is obtained by adopting a passive magnetooptic glass electronic current transformer, and a high-speed acquiring circuit is controlled by a CPLD (Complex Programmable Logic Device) for recording and sampling 625KHz travelling wave data and starting the sampling of 20KHz criterion data. When the transmission line fails, the travelling wave distance measurement device judges whether the transmission line fails through the sampled 20KHz data, and controls a 625KHz high-speed sampling part to completely record high-speed sampled data comprising travelling signals and sends data to a background computer through communication, and the background computer automatically computes and recognizes a failed travelling wave head through a wavelet algorithm after obtaining dual-end circuit data, and realizes failure location of the transmission line according to different moments of the wave head arriving at a dual-end bus.
