[0024] The bottom of the fixed block 1 is slidably connected with a connecting block 19 in a through-shaped manner, and one end of the connecting block 19 is fixedly connected with a clamping block 20. The sliding of the connecting block 19 can drive the clamping block 20 to control the opening width, and then can be controlled according to the installation conditions, so as to form an adjustable condition that is easy to install. Connecting rods 13 are fixedly connected to both sides of the sliding rod 12, and one end of the connecting rod 13 is fixedly connected to a balancing rod 14.
