In the transmission rod bearing block of the coaxial telescopic rod, the end part of the fixing plate is provided with the fixing ring, the surface of the fixing ring is provided with a threaded hole, and the fixing ring is fixed with the inner pipe through a bolt.

In the transmission rod bearing block of the coaxial telescopic rod, the inner pipe is provided with a fixing groove matched with the fixing plate.

In the transmission rod bearing seat of the coaxial telescopic rod, the inner side wall of the fixing ring is matched with the fixing groove and the guide groove.

In the above-mentioned drive rod bearing block of the coaxial telescopic rod, the fixing plate has elasticity.

In the above-mentioned drive rod bearing block of the coaxial telescopic rod, the side wall of the bearing block body between the fixed plates is a plane.

Compared with the prior art, the utility model has the following beneficial effects:

1. the inner pipe comprises a bearing seat main body fixed at the end part of the inner pipe, wherein symmetrical strip-shaped fixing plates are arranged on the side part of the bearing seat main body, fixing blocks are arranged on the inner wall of the fixing plates, and fixing holes matched with the fixing blocks are formed in the side surface of the inner pipe; during the installation, insert the bearing frame main part from the interior pipe end that corresponds the side, when fixed block on the fixed plate reachs the fixed orifices position, the fixed block is gone into in the fixed orifices along the situation card, realizes spacingly, is connected fixedly with the inner tube lateral wall, need not to require the inner tube wall thickness, effectively reduces the whole volume of device, promotes the use convenience, and reduces the dependence to the bolt, has the convenient characteristics of installation.

2. The end part of the fixing plate is provided with a fixing ring, the surface of the fixing ring is provided with a threaded hole, and the fixing ring is fixed with an inner tube through a bolt; realize being connected between solid fixed ring and the inner tube through the bolt, strengthen fixed reliability, effectively reduce rocking and the shake that the working part produced to the influence of bearing frame main part, further promote the reliability.

3. The inner pipe is provided with the fixing groove matched with the fixing plate, the fixing plate is embedded in the fixing groove, the overall size of the bearing seat main body matched with the inner pipe is reduced, the fixing groove can realize auxiliary limiting on the fixing plate, and the stability after connection is further improved.
