As further improvement of the utility model, two clamping mechanisms that are provided with side by side on this open slot, this two clamping mechanism is two groups of quick detach assemblies being located at these open slot both sides, these two groups of quick detach assemblies comprise two groups of lugs being located at these open slot both sides side by side, movable two of passing these two groups of lugs regulate bolts, are fixed in this simultaneously and two regulate the transverse axis of bolt end and end rotational fixation in the spanner of this transverse axis respectively, this two adjustings bolt other end is rotated with two setting nuts respectively, and this spanner end has eccentric cam.
As further improvement of the utility model, this spanner end forms two feets side by side, this two feet wear respectively and rotational fixation in these transverse axis two ends, and this two feets outer rim forms eccentric cam respectively.
As further improvement of the utility model, this spanner forms U type both ends, and each end forms two feets side by side, the feet on these both ends wear respectively and rotational fixation in this transverse axis, and each feet outer rim forms eccentric cam.
As further improvement of the utility model, two clamping mechanisms that are provided with side by side on this open slot, this two clamping mechanism are two groups of lugs being located at these open slot both sides, and every group of lug tightens up by set screw and setting nut respectively and this beam tube is clamped this standpipe.
As further improvement of the utility model, this detent mechanism is the positioning convex portion on detent on this standpipe and this beam tube, and this positioning convex portion is corresponding and can stretch into this detent.
As further improvement of the utility model, this detent mechanism is the fixing screw on detent on this standpipe and this beam tube, and this fixing screw is corresponding and can stretch into this detent.
Useful technique effect of the present utility model is: described beam tube and standpipe bonded assembly partly have open slot, and be provided with two clamping mechanisms side by side in the open slot both sides, design makes beam tube can stablize clamp fitting in this standpipe like this, be provided with the detent mechanism that prevents that the beam tube relative riser from rotating simultaneously between this beam tube and the standpipe, like this beam tube this standpipe of clamp fitting securely.
These two clamping mechanisms can be two quick detach assemblies or two screw bolt and nut, this detent mechanism can be the positioning convex portion on the detent on this standpipe and this beam tube, this positioning convex portion is corresponding and can stretch into this detent, this detent mechanism also can be the fixing screw on the detent on this standpipe and this beam tube, and this fixing screw is corresponding and can stretch into this detent.
