Its main purpose is to effectively protect the safety of children and minimize injuries in the event of a vehicle collision or emergency braking. It usually includes a seat body, handles, and a lifting and mounting structure.

[0003] Among them, the handle is a key component of the basket-type safety seat. It is the component that is used most frequently and is most prone to failure in daily life. If the handle falls off and fails, the child may fall out of the basket and suffer serious injuries. The function of the handle generally requires the ability to shift forward and backward, and be locked in each gear and withstand a weight of more than 20kg (the weight of the child + the basket itself). Excessive shaking will also bring a bad experience to consumers.

[0004] The existing handle installation structure often requires loosening the nut structure when adjusting the gear position. This creates the risk of the handle falling off and becoming ineffective due to the loose nut. The lack of a safe and convenient installation structure results in the handle easily becoming ineffective due to gear adjustment during use or being easily disassembled and having a greater risk of falling off, making the handle relatively unsafe.
