Clamping seat of telescopic rod

A clamping seat of a telescopic rod for clamping an inner pipe and an outer pipe, comprising:

• a pipe seat, comprising an inner pipe space, wherein a diameter of the inner pipe space is corresponding to a diameter of the inner pipe, an outer pipe space, wherein a diameter of the outer pipe space is corresponding to a diameter of the outer pipe, a side opening and a side space, wherein the inner pipe space is communicated with the outer pipe space and respectively allows the inner pipe and the outer pipe to insert, the side opening is positioned next to the inner pipe space, and the side space is positioned next to the outer pipe space;
• a movable clamp, comprising an arc block and a screwing member, the arc block pivoted on the pipe seat and adjacent to the side opening, the screwing member passing through the arc block and the pipe seat and tightly pressing the arc block, wherein the arc block passes through the side opening and transversely passes into the inner pipe space to tightly press and fix the inner pipe;
• a fixed clamp, comprising a clamping plate and a tightening bolt, the clamping plate placed in the side space, and the tightening bolt screwed through the pipe seat to press against the clamping plate, wherein the clamping plate transversely passes into the outer pipe space to press the outer pipe;
• and
• a bushing, comprising a passing-into end, a passing-out end, a transverse notch adjacent to the passing-into end, and an axial notch communicated with the transverse notch and extending to the passing-out end;
• wherein the inner pipe passes into the inner pipe spaced at an interval of the bushing.
