And convenient for holding.
Anti-rotational telescopic rod described in the utility model, including several on-circular cross-section telescoping tubes and several lockings clamp dress
Set, locking clamping device includes on-circular cross-section tubular element, and one end of on-circular cross-section tubular element is looped end, looped end with it is non-
Circular section telescoping tube outer tube is fixedly connected, and the other end is open end, and open end is slidably connected with on-circular cross-section telescoping tube inner tube, opens
It is set on mouthful end there are two clamping ring, is provided with notch between two clamping rings；Locking clamping device further includes screw, and screw one end is worn
Two clamping rings to be crossed, and are fixedly connected with locking pin, rotation is provided with clamping bar on locking pin, and locking pin is biased,
Clamping bar is set to form eccentric locking mechanism.
It is equipped with lever bracket between the clamping bar and clamping ring, screw is equipped between the head and clamping ring of screw and is positioned
Part positions convenient for screw, and Camlock movement is made to be easier to carry out.
It is equipped with hollow pins in the clamping ring, spring is equipped between hollow pins and screw locating piece.
The on-circular cross-section stretches pipe end equipped with bottom plug.
The cross section of the on-circular cross-section telescoping tube and on-circular cross-section tubular element prevents from mutually rotating in non-circular,
Preferably, cross section is oval or cross section both ends are the identical semicircle of radius, centre for two it is parallel and with semicircle
Tangent straight line (i.e. stadium shape, as shown in Figure 6) or cross section both ends are the different circular arc of radius, and centre is non-parallel for two
And the tangent straight line (as shown in Figure 7) with circular arc.
Possessed beneficial effect is the utility model compared with prior art:
Anti-rotational telescopic rod described in the utility model has locking clamping device, can make telescopic rod axial restraint；It stretches
The draw and tubular element are on-circular cross-section, can prevent telescopic rod from circumferentially rotating, and lock the body of rod of clamping device and telescopic rod
(i.e. telescoping tube) good compatibility, good rigidity operate safer；And compared with using circular pin, the telescopic rod bar of on-circular cross-section
Body (i.e. telescoping tube) provides additional safer gripping and control, operates more comfortable.
