[0020] 5. In the present invention, a reinforcement rod is provided on one side of the bottom support frame close to the slide rail, which can not only ensure that the slide rail will not loosen and slide after long-term use, but also ensure that the bottom support frame will not be deformed when the pulley slides in the slide rail.
[0021] 6. The present invention provides a foot pedal on the second connecting rod, and the limit block is used to fix the first connecting rod and the second connecting rod at an obtuse angle, which is convenient for the user to step on with force, avoids the situation where it is difficult to exert force due to the pedal being too steep, increases the user's comfort when stepping, thereby making the stepping force greater and making it easier to lower the coffee table.
[0022] 7. The pulley and the support rods in the present invention are both rotatably connected, so that the desktop can be raised and lowered smoothly and stably; and a connecting rod is arranged between the support rods, and a rotating seat is arranged on the connecting rod, which can also ensure that the cylinder will not cause a large impact force on the desktop when extending and retracting, and prevent the objects on the desktop from falling or tilting due to excessive vibration.
[0023] 8. A limit block is set at the connection between connecting rod 1 and connecting rod 2. When the desktop of the coffee table is raised for use, the limit block will prevent the descending device from descending due to the pressure of the desktop. In other words, the desktop can only be lowered when connecting rod 2 is stepped on. This design can ensure that the desktop is fixed at the same height when in use, which is convenient for use.
[0024] 9. Linkage three is used to support the descending device on the ground, making the descending device more stable. BRIEF DESCRIPTION OF THE DRAWINGS
