It should be emphasized that a sensor pad is provided above the support plate 25 of the present invention, and a lower limit sensor is fixed on the sensor pad. position, the sensor block is used to fix the lower limit sensor.

Below the support plate 25 and at a position aligned with the sensor block, a sensor bracket is provided, and an upper sensor is provided on the sensor bracket, wherein the sensor bracket is used to fix the upper sensor, and when the jacking unit is raised, the upper sensor Sensors are used to define the exact exact position of the ascent. In addition, an upper limit sensor is provided below the support plate 25, and when the jacking mechanism is raised, the upper limit sensor is used to detect the highest safety limit limit of the rise of the bottom plate 29.

To sum up, the present invention can realize accurate positioning of the steering surface substrate by arranging the first positioning pin 22 and the second positioning pin on the positioning plate 23 . By arranging the first proximity sensor next to the first positioning pin 22 and the second proximity sensor next to the second positioning pin, the tilt detection function of the steering surface substrate can be realized to ensure that the steering surface substrate is placed correctly and in a stable state. The present invention can reduce the activity space and spatial layout occupied by the lead screw 28 by arranging the first guide rod sleeve 24 to the fourth guide rod sleeve above the support plate 25 and accommodating grooves on the bottom plate 29 . The invention can improve the plane positioning efficiency and realize the jacking movement at the same time, the overall internal structure of the mechanism is simple, and it is convenient for processing, assembly and maintenance.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention.
