ABSTRACT:
The disclosure concerns a device for clamping two axially telescoping rods in a selected telescoped position, wherein the device includes a case supported at the end of the outside one of the two rods and the case encloses an annular bush wrapped around the inside one of the two rods. One side of the bush is open for defining an axial gap. Terminal flanges extend away from the bush at opposite sides of the gap. A shaft extends from the second of the terminal portions, through the first of the terminal portions and then outside the case. A two-position cam is journaled to the shaft and is shaped to engage the exterior of the case. As the cam is moved between its two positions, it selectively draws the terminal portion flanges together or permits them to move apart for selectively clamping or releasing the bush on the rod. A spring normally biases the terminal portion flanges apart. A nut screw-threadedly received on the shaft is adjustable along the shaft for defining the initial position of the second terminal portion with respect to the first terminal portion.
