Secondly, if satisfy the ergonomic reduction equipment line height by force, can face the not enough problem of equipment line downside space in mechanical design, equipment line upside loads the anchor clamps tray, after the operation is accomplished to the final station operator, the tray can be fallen and is sent back the line head by the chain from the line body downside by the lift, if equipment line height is low excessively, passback structure and lift will not have enough activity space, even the space is reluctant enough, also have to compress original structure in mechanical design, do so will reduce the reliability and the security of main equipment line.

Thirdly, from the viewpoint of project cost and project time, one assembly line often not only provides final assembly service for one type of seats, but also solves the problem along with the conventional assembly line from other aspects, namely, the assembly line installation reference is designed at a position lower than the ground height (trench), so that the maintenance, upgrading and reconstruction of the assembly line are not facilitated, and safety risks are also caused.

In order to solve the technical problems, the applicant designs a commercial vehicle suspension seat U-shaped assembly line, but because the traditional seat tray mechanism cannot be used on the assembly line, redesigning a special on-line clamp mechanism for a commercial vehicle seat assembly is an urgent need.
