[0003] In the prior art, most LCD TV brackets are fixed. After drilling holes on the wall and installing them, the TV is fixed. After the TV is installed on the bracket, it cannot be moved up and down, nor can it be moved forward, backward, left, and right, which will cause inconvenience in viewing. Because the TV cannot be moved up and down, it is impossible to clean the wall behind the TV. The TV needs to be taken off the bracket before it can be cleaned. During decoration, the socket and network cable jack are usually fixed on the wall behind the TV. After the TV is installed, it is inconvenient to connect the TV power plug and the network cable plug to the corresponding junction box. The TV needs to be removed or the lower end of the TV needs to be lifted before operation. After the TV bracket is fixed, the position of the TV cannot be adjusted up and down, forward and backward, left and right according to the viewing angles of different people, resulting in poor viewing effect.

At the same time, when the television set is in operation and temperature is generated, the outer side of the heat dissipation fin 22 contacts the outer side of the television set to exchange heat, and the heat emitted by the television set is introduced into the interior of the fixed shell 19, and contacts with the conduction plate 21. The heat exchange process is performed between the conduction plate 21 and the heat dissipation fins 22, so that the heat dissipated can be dissipated. At the same time, the heat dissipation fan 26 is started to increase the air circulation inside the fixed shell 19, so that the heat exchange process of the dissipated heat is better. Through the design of the heat dissipation component 18, the TV can be effectively cooled to prevent the high temperature generated by the operation of the TV from affecting its own operation. When the TV needs to be adjusted up and down, the two sets of nuts 30 are rotated to cooperate with the connecting plate 29 to displace the screw rod 27, driving the second connecting frame 3 to adjust the up and down angles, so that the TV clamped and installed by the limit frame 5 can be adjusted up and down, which is convenient for use.
