使用时，将孩童的两脚踏在底板24的上方并位于前板25的前侧， 使得孩童坐在坐板27上并使得安全带45阻挡在孩童的腹部以起到安全防护作用，孩童背靠在背板46上；成人用手握住推管22向外推拉，就能将孩童推移，若孩童想要睡觉时，可以先拧松两个第二旋钮螺钉23，并慢慢向下翻转背板46，直到端管29的下侧侧面贴合在前管20的上侧侧面上，就能将背板46放平，以供孩童舒适地睡觉；同时也可以通过旋紧两个第二旋钮螺钉23将背板46定位在任意一个角度；若想要调节儿童的坐卧高度时，先拧松第一旋钮螺钉37，然后手握手柄39并转动摇柄38，进而带动驱动轴36和第三带轮34转动，从而借助第一皮带9和第一带轮5带动其中一个转轴4转动，同时依靠第四带轮51、第二皮带10与第二带轮40的传动连接带动另一个转轴4同向转动，进而带动每个转动板7同向转动，从而借助连接在每个转动板7上的牵引板8和两个横梁11在保证水平状态的前提下顺时针或逆时针转动，从而借助托梁12带动车架组件上升或下降，且上升或下降的同时会向前或向后移动一定距离，进而实现了调整孩童坐卧高度的作用，调整后须再次拧紧第一旋钮螺钉37；位于底板24上方且位于前板25后侧的区域可以用来放置杂物，收纳空间较大，且存取方便。
推车是孩童远距离出行时必备的“交通工具”，推车需要有成人协助推着或者拉着才能移动；现有的推车功能单一，结构单薄，仅能作为孩童的出行工具使用，使用范围较小；本实用新型具备升降功能，坐卧两用，功能多样，操作简单方便；且结构牢固，还可用来运输物品，扩大了适用范围。
最后应说明的是：以上实施例仅用以说明本实用新型的技术方案，而非对其限制；尽管参照前述实施例对本实用新型进行了详细的说明，本领域的技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行同等替换；而这些修改或者替换，并不使相应技术方案的本质脱离本实用新型各实 施例技术方案的精神与范围。
