The telescopic bracket includes two telescopic units arranged side by side and at intervals, and each telescopic unit includes a plurality of rods connected in sequence.
[0003] The existing telescopic machine driving mechanism generally installs the driving motor on the supporting leg at one end, resulting in a large torque transmitted from the driving motor to the other end of the telescopic machine.

As a result, the overall weight of the equipment is too large, the structure is heavy, and it is not conducive to the mobility of the roller telescopic machine.
[0004] For this purpose, we propose a roller telescopic machine with high stability. Utility Model Content
