A locating/controlling structure for telescopic tube including an elliptic outer tube. A rotary button is rotatably disposed at one end of the outer tube. The rotary button is connected with an elliptic rod passing through the outer tube. An inner tube is telescopically nested in the outer tube. One end of the inner tube fitted in the outer tube is provided with a cock body formed with a central circular hole through which the elliptic rod is passed. The cock body has a stop section protruding from the inner tube. The stop section is formed with two radially opposite receptacles. A movable block is disposed in each of the receptacles. Each movable block has a contacting face complementary to the inner circumference of the outer tube. When the rotary button is turned to drive the elliptic rod to rotate about the axis thereof, due to the different diameters of the elliptic rod, the elliptic rod pushes the two movable blocks to radially outward move, whereby the contacting faces of the movable blocks press and abut against the inner circumference of the outer tube to locate the inner and outer tubes.

A bus bar panel system utilizes a quick acting and simplified fastening system for making connections. The bus bar is preferably pre-perforated along the edges, although holes may be drilled at the time of fastening. The fastening system uses a stud having threads on one end for receiving the usual washers and nut. On the other end, usually away from the installer, the stud is provided with flats which engage an open slot or yoke on a keeper clip. The clip has a gauge flange to engage the edge of the bar or clamp through which the stud extends. The transverse dimensions of the open slot are related to the flats and the length of the slot to the distance of the perforations from the edge of the bar. The clip also includes a spring section which grabs the end of the stud holding the clip in place so that the installer has both hands free to secure the nut and washers. The clip, while providing the requisite area and stiffness for a good electrical connection, occupies very little space axially of the stud to fit between bars of a common phase. A wide variety of connections may be made more easily with fewer parts less apt to be dropped in locations which would normally require partial disassembly of the panel system or housing.
