A connecting beam 2 is provided under the desktop panel 1, and both ends of the beam 2 are fixed on the table leg frame tube 3. The table leg frame tube 3 includes an upper table leg frame 31 and a lower table leg frame 32. The upper table leg frame 31 and the lower table leg frame 32 are telescopically and slidably connected. The upper end of the upper table leg frame 31 is fixedly connected to the desktop panel 1, and the bottom of the lower table leg frame 32 is fixedly connected to the base 7. The table leg frame tube 3 is communicated with the interior of the connecting beam 2 and is provided with a bilateral drive mechanism. The bilateral drive mechanism includes a pulley assembly 4, a pulley bracket 5 and a wire rope 6. The pulley assembly 4 includes multiple pulleys. Each pulley of the pulley assembly 4 is rotatably set on the table leg frame tube 3 and the pulley bracket 5. Both ends of the wire rope 6 are fixed on the pulley bracket 5. The wire rope 6 is wound around the pulley so that the wire rope 6 is always in a taut state. When the lifting mechanism on one side lifts the upper table leg frame 31 on one side, the pulley and the wire rope 6 will cause the upper table leg frame 31 on the other side to move upward at the same time, thereby raising the entire table top 1 and realizing the height adjustment of the table top.

[0018] The roller pulley assembly 4 includes two groups, which are symmetrically arranged inside the upper table leg frame 31 and the lower table leg frame 32 with the two groups of pulley brackets 5. Each group of roller pulley assembly 4 includes pulley one 41, pulley two 42, pulley three 43, and pulley four 44. Pulley one 41, the upper table leg bracket 32, and the pulley bracket 5 are rotatably connected together by pins. Pulley three 43 is set at the lower end of the pulley bracket 5, and pulley two 42 and pulley four 44 are respectively set at the upper and lower ends of the lower leg table frame 32. The head of the wire rope 6 is fixed to the lower end of the pulley bracket 5, first bypasses pulley three 43, then bypasses pulley four 44, continues to bypass pulley one 41, then bypasses pulley one 41 at the other end, then bypasses pulley three 43 at the same side end, and then bypasses pulley two 42 at the same side end. The wire rope 6 is finally fixed to the bottom end of the pulley bracket 5 at this side end to complete the connection.

[0019] The inner side of one leg frame tube 3 is provided with a lifting mechanism 8, which drives the upper leg frame 31 on one side to rise, and under the action of the double-sided driving mechanism, drives the upper leg frame 31 on the other side to rise simultaneously. Preferably, the lifting mechanism is a cylinder, one end of which is fixedly mounted on the base 7 at the bottom of the table top, and the other end of the gas pressure rod is fixed to the bottom of the table top 1, and the table top 1 is lifted by the cylinder.
