[0016] In this embodiment, the pedal assembly 2 includes a pedal bracket 21, a pedal switch 22, a pedal sheet metal 23 and a pedal screw 24. The pedal bracket 21 is fixed to the bottom of the base 1, the pedal switch 22 is fixed to the pedal sheet metal 23, the pedal sheet metal 23 is rotatably connected to the pedal bracket 21 through the pedal screw 24, and one end of the pedal sheet metal 23 is located directly below the lifting top block 3. By stepping on the pedal switch 22, the pedal sheet metal 23 lifts the lifting top block 3 through the lever action, and the lifting top block 3 can support the lifting rod 7.

[0017] In this embodiment, the lifting rod 7 includes a pneumatic rod 71 and a pneumatic sleeve 72. The pneumatic rod 71 and the pneumatic sleeve 72 are assembled together and filled with high-pressure nitrogen to form a gas spring. The pneumatic rod 71 is fixed to the lower end cover 4 of the inner sleeve by a lower end thread. A valve is installed at the lower end of the pneumatic rod 71, and the pneumatic sleeve 72 is fixed to the upper end cover 8 of the outer sleeve by an upper end thread.

[0018] In this embodiment, a rotating shaft concave wheel 10 with crown teeth is installed in each of the left and right axial holes on the upper end cover 8 of the outer sleeve, a locking gear 11 is installed in the left axial hole of the flip frame 9, and a return spring 12 is installed on the locking gear 11. The locking gear 11 is tightened and loosened by screwing the hand screw 13 into the depth of the left axial hole of the upper end cover 8 of the outer sleeve. When screwed in to the deepest, the locking gear 11 presses the rotating shaft concave wheel 10; a rotating shaft cam 14 is installed in the right axial hole of the flip frame 9, the rotating shaft cam 14 cooperates with the rotating shaft concave wheel 10 and is locked in the right axial hole of the upper end cover 8 of the outer sleeve by an adjusting screw 15, and a spring piece 16 is provided between the adjusting screw 15 and the rotating shaft cam 14.

[0019] In this embodiment, lifting bearings 17 are fixed on the four sides of the lifting inner sleeve 5, and reinforcing ribs adapted to the lifting bearings 17 are provided in the vertical direction around the inner wall of the lifting outer sleeve 6, and the lifting bearings 17 can slide up and down in the vertical direction along the reinforcing ribs.

[0020] In this embodiment, four universal casters 18 are provided on the four corners of the base 1, so that it can be easily moved.

[0021] Working principle: During work, when it is necessary to rise, step on the foot switch 22, and the foot sheet metal 23 rotates around the foot screw 24. Through the principle of leverage, one end of the foot sheet metal 23 pushes against the lifting top block 3, and the lifting top block 3 slides upward in the lower end cover 4 of the inner sleeve to hold the valve of the pneumatic rod 71. Due to the limitation of the lifting bearing 17 and the reinforcing ribs between the lifting inner sleeve 5 and the lifting outer sleeve 6, the pneumatic sleeve 72 rises under the action of air pressure and drives the upper end cover 8 of the outer sleeve to rise, and then rises vertically with the lifting outer sleeve 6. When the required height is reached, release the foot switch 22, and the height is locked at this time; when it is necessary to descend, step on the foot switch 22, the lifting top block 3 holds the valve of the pneumatic rod 71, and presses the top downward with a force exceeding the air pressure, and the pneumatic sleeve 72 will vertically rise. The upper cover 8 of the outer jacket descends and drives it to descend. When it descends to the required height, the foot switch 22 is released, and the height is locked at this time; when the inclination angle of the top needs to be adjusted, the hand screw 13 is turned counterclockwise. At this time, the return spring 12 drives the locking gear 11 to leave the shaft cam 10, thereby releasing the lock, and the flip frame 9 can be rotated to adjust the angle. After the angle is adjusted, the hand screw 13 is turned clockwise until the locking gear 11 presses the shaft cam 10; if the force required for the flip frame 9 to rotate is to be controlled, the adjusting screw 15 can be loosened and tightened to adjust the pressing force of the spring piece 16 on the shaft cam 14 and the shaft cam 10, thereby controlling the force required for the flip frame 9 to rotate.

[0022] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
