DETAILED DESCRIPTION

[0016] The utility model solves the deformation caused by fatigue or strong external force. The leg 1 is mainly made of bent plate and welded as a whole. The outer visible surface is bent as a whole to reduce the exposed welds and improve the aesthetics of the leg 1. The leg 1 is provided with reinforcing ribs to improve the overall strength of the leg 1. The leg 1 is provided with weight-reducing holes. The overall structure is simple and the material cost is greatly reduced compared with the profile structure. Eight first mounting interfaces 15 are symmetrically arranged near the seat surface of the seat component 2 and located on the upper part of the leg 1 and are connected and fixed to the seat surface of the seat component 2. Three second mounting interfaces 16 are reserved at the upper part near the vehicle body 3 and located at the rear end 1 of the leg, and two third mounting interfaces 17 are reserved at the lower part. The rear end of the leg 1 is connected and fixed to the vehicle body 3 through the second mounting interface 16 and the third mounting interface 17 to ensure its stable installation. Figure 1 and Figure 2 shown.

[0017] Leg installation: insert the T-slot bolt 7 into the slide groove of the vehicle body 1, then insert the second mounting interface 16 and the third mounting interface 17 of the leg 1 into the mounting base bolt 18 and the T-slot bolt 7 respectively, and finally install the first flat washer 4, the standard spring washer 5, and the type 1 hexagonal nut M126 at the upper part of the rear end of the leg 1, a total of three places; install the second flat washer 8, the first butterfly spring 9, the type 1 hexagonal nut M1010 and the cap nut M1011 at the lower part of the rear end of the leg 1, a total of 2 places. It can be seen that its installation and overhaul and maintenance are quick and convenient, see Figure 3 shown.

[0018] Seat installation: Insert the slider 19 into the slide groove of the seat component 2 installation profile, then drop the seat component 2 onto the leg 1 component, and align the mounting hole of the slider 19 with the first mounting interface 15 on the leg 1. Finally, install the third flat washer 12, the second butterfly spring 13 and the hexagonal head bolt with full thread M10X2514 from the bottom of the seat component 2, a total of 8 locations, see Figure 4 shown.
