The connection between the main shaft and the main shaft gear should be free of gaps. In order to meet this requirement, there are mainly two schemes for the connection between the main shaft and the main shaft gear. Option 1, one or both ends of the main shaft and the main shaft gear are connected by flat keys. This scheme requires that the matching clearance between the main shaft and the gear hub is small, so it is difficult to process, assemble and maintain; Option 2, one or both ends of the main shaft and the main shaft gear Using taper-sleeve connection, this solution has good performance, but high cost and poor rigidity
The existing screw generally includes a round table-shaped nail body with one large end and one small end, a threaded section is provided on the radial circumference of the nail body, a small end of the nail body is provided with an inclined tip, and the large end of the nail body is provided with a nail cover. , generally used on materials that are softer than the screw, and drill into the object to be nailed through its own rotation. When drilling, the thread plays the role of rotary cutting, so that the screw is drilled forward, but when the thread cuts the object to be nailed When it is shaken for a long time, the tightening force of the screw in the axial direction is not enough, it is easy to loosen, and there is a potential safety hazard.
Blind rivets are a type of flying rivets for single-sided riveting, but they must be riveted manually, electrically, and automatically using special tools.

In the prior art, spring pads are fixed to the seat pan or to the height adjuster tube. However, in the absence of a seat pan, additional components are required to secure the spring pads to prevent movement of the spring pads in the longitudinal direction of the vehicle. FIG. 1 shows such a seat spring pad 2 , which is fixed to the seat pad 1 by means of additional fixing parts 4 . Additional weight is added due to the use of additional fixing parts and a separate step is required in the assembly process to connect the fixing parts to the spring pads. During use, there may be noise between the spring cushion and the seat cushion
