The lifting rod 41 is rotatably connected to the other end. The first stable unit 31 and the second stable unit 71 are parallel and have the same length.

[0027] By mounting the lifting mechanism 2 on the lifting base 1 and vertically arranging the mounting bracket 3 connected to the side wall of the lifting mechanism 2 on the lifting base 1 for supporting the entire lifting platform, the stability of the lifting platform base can be ensured, the strength thereof can be ensured, and damage thereof can be avoided.

[0028] The transmission bracket 6 is arranged below the stage 5. The transmission bracket 6 and the mounting bracket 3 are parallel and have the same length. The first stable unit 31 and the second stable unit 71 are arranged at the ends of the transmission bracket 6 and the mounting bracket 3. The stable structure 4 comprises the parallel and same-length lifting rod 41 and the stabilizing rod 42. The lifting rod 41, the first stable unit 31, the stabilizing rod 42 and the second stable unit 71 collectively form a parallelogram. According to the law of the parallelogram, the parallel relationship of the four sides of the parallelogram does not change with the change of the internal angle. Since the mounting bracket 3 is stably and vertically connected to the lifting base 1, the extension line of the transmission bracket 6 will be stably perpendicular to the lifting base 1 and the stage 5 regardless of the driving of the lifting mechanism 2 to operate the lifting rod 41. This structure can effectively improve the stability of the entire structure, facilitate height adjustment, and ensure the strength and stability of the entire structure.

[0029] The lifting mechanism 2 is driven to be connected to the lifting rod 41, and the stabilizing rod 42 is between the lifting rod 41 and the lifting mechanism 2, the height of the object table 5 can be efficiently adjusted through the lifting rod 41, and the stabilizing rod 42 does not need to be adjusted additionally, and will move with the lifting rod 41 and automatically stabilize the whole lifting platform, so that the whole adjustment process is more efficient.

[0030] The lifting mechanism 2 can be a driving motor with a pedal, a telescopic rod is arranged on the driving motor, and the lifting rod 41 is parallel to the object table 5 and is provided with a transmission rod, the end of the telescopic rod away from the motor is rotationally connected to the transmission rod, the motor can be easily started through the pedal, so that the lifting rod 41 is lifted or lowered by the motor, and the height of the lifting platform can be efficiently and flexibly adjusted through the structure.

[0031] In combination with the drawings, Figs. 1-2 In an embodiment of the present application, the transmission bracket 6 comprises a transmission frame 61 and a connecting frame 7, the transmission frame 61 is connected to the bottom edge of the object table 5, and the transmission frame 61 and the object table 5 are coaxially arranged; the connecting frame 7 is vertically connected to the bottom edge of the transmission frame 61, the second stabilizing unit 71 is arranged at the end of the connecting frame 7 away from the transmission frame 61, and the side wall of the connecting frame 7 faces the transmission frame 61 and is provided with a reinforcing rod, and the reinforcing rod, the connecting frame 7 and the transmission frame 61 form a triangular reinforcing space.

[0032] The transmission bracket 6 transmits the force on the object table 5 to the stabilizing structure 4 as evenly as possible to guarantee the structural strength, the transmission frame 61 and the object table 5 are coaxially arranged, which can make the force on the transmission frame 61 more uniform and avoid damage to the object table 5, and the connecting frame 7 and the transmission frame 61 form a triangular reinforcing space through the reinforcing frame, which strengthens the connection between the connecting frame 7 and the transmission frame 61 and guarantees the stability of the structure.

[0034] Because the length of the transmission frame 61 is limited after being connected to the object table 5, the transmission frame 61 cannot completely cover the bottom surface of the object table 5, in order to make the force more uniform, the corner of the transmission frame 61 is extended towards the corner of the object table 5 and is provided with a tripod for reinforcement, which can make the contact area between the transmission frame 61 and the object table 5 larger and more uniform, and can effectively protect the object table 5 from being damaged.
