As shown in fig. 3 and 6, the linkage mechanism may be one type of mechanical component, a mechanism composed of relatively moving members coupled by a low pair (revolute pair or prismatic pair). The contact surfaces of the revolute pair and the sliding pair in the link mechanism are cylindrical surfaces and planes, so that the link mechanism is wear-resistant, simple and convenient to manufacture and easy to obtain higher manufacturing precision. In the link mechanism, when the active rod moves to be collinear with the link, the active rod cannot continuously drive the link to move, and a self-locking phenomenon occurs;

a slider-crank mechanism is a typical type of linkage mechanism that converts rotation into translation. In the crank-slider mechanism, a connecting rod is driven to move through the rotation of a crank, so that a slider connected with the connecting rod reciprocates.

When the moving crank member 32 (actively) rotates around the first hinge shaft 34, the connecting rod member 31 drives the first clamping block 2 (driven) to move in the groove 13 on the back of the seat body 1 along the clamping direction. The connecting rod 31 may be a straight rod, when the crank 32 rotates to be collinear with the connecting rod 31, that is, when the second hinge shaft 35 is located on the axis connecting line of the third hinge shaft 36 and the first hinge shaft 34, that is, when the three hinge points in the slider-crank mechanism described above are collinear to form a mechanical self-locking condition, at this time, the clamping portion 22 drives the first clamping block 2 to move to the clamping position in the clamping direction, the first clamping block 2 reaches the lower limit position, the locking force reaches the maximum, and thus the connecting rod mechanism is in the self-locking state, as shown in fig. 2. Of course, when the three hinge points in the slider-crank mechanism are not collinear, the first clamping block 2 leaves the lower limit position, and the quick-mounting plate is released.
