working principle:

Align the basket and put it on the base, the hook bar pushes the hook and compresses the torsion spring so that the hook opens and then falls into the slot, the elastic force of the torsion spring makes the front hook and the rear hook reset and lock the hook rod.

When it is necessary to lift the basket, pull the pulling part forward, and the pulling part will pull the lower end of the front hook to rotate forward around its hinge axis, and the front hook will drive the lower end of the rear hook to rotate around its hinge axis through the connecting rod, and the hook will go up The part is disengaged from the hook bar, and the basket and the base can be separated. Release the pulling part, and the elastic force of the torsion spring resets the front hook and the rear hook.

Press the control button, the control button will compress the top pressure spring, and the adjustment pin at the other end of the control button will be pulled out from the insertion hole and the height adjustment hole. It stretches to adjust the height of the adjustable feet to adjust the angle of the baby seat. Release the control button. The space is locked horizontally by the bolt and cannot be moved.

When the fixed clip needs to be telescopic, press the push button 54 backwards, press the button to push the push rod 540, and the push rod 540 pushes the longitudinal slider 543 to slide longitudinally in the longitudinal sliding hole 542, and the sliding pin is pushed obliquely on the longitudinal slider 543 Hole 547 obliquely pushes sliding pin 548 to drive horizontal slider 545, because sliding pin 548 is limited by lateral limit sliding pin hole 546 and can only slide horizontally, compresses and presses return spring 549, and horizontal latch 503 exits hole 511 and longitudinal adjustment hole 521. At this time, relative sliding adjustment between the slide rail 501 and the slide bar 502 is possible.

Release the push button 54 and press the return spring 549 to reset and push the horizontal pin 503 into the perforation 511 and the longitudinal adjustment hole 521. Now, the slide rail 501 and the slide bar 502 are blocked by the horizontal pin 503 and cannot slide relatively.
