Since there are more types of TV programs, there are more types of rockers used in TVs. , can be mainly divided into three types: with seat, full remote control and full manual. Only some of the rocker arms have the function of arm retraction.

Considering that the size and weight of general rocker arm equipment are very large, the installation of the rocker arm must be based on safety.
