Technical Problem

The height adjustment mechanism of the existing trailer arm is easily affected when used in sand and dust or tiny particulate media, resulting in the screw not being easy to rotate, affecting the accuracy of height adjustment, and inconvenient operation.

Method used

The trailer arm design is adopted with rack and rack, which drives the gears to rotate through the handle, so that the gears move up and down relative to the rack, thereby realizing the height adjustment of the trailer ball head mechanism. The linear contact between the gear and the rack and the presence of gaps can accommodate sand and dust and particles, improving transmission efficiency and convenience.

Benefits of technology

It realizes efficient and convenient height adjustment in sand and dust or tiny particle media, avoids the influence of sand and dust, and improves the adaptability and convenience of the trailer arm.
