The invention relates to the technical field of carton packaging, and discloses a herringbone ladder convenient to move. The herringbone ladder comprises a connecting rod, two groups of hinges, four groups of support rods and a plurality of groups of pedals, the two groups of hinges are respectively arranged on the left side and the right side of the connecting rod, the bottom side walls of the two groups of hinges are respectively and movably provided with two groups of support rods, and a connecting device, an extending device, a limiting device, a fixing device and a clamping device are arranged outside the connecting rod. According to the herringbone ladder convenient to move, the gravity center of a worker deviates to one side of the herringbone ladder, the worker can deflect the side, away from the gravity center, of the herringbone ladder with legs, the two groups of connecting movable grooves are each in a rounded rectangle shape, so that when the herringbone ladder deflects, the connecting movable grooves cannot block rotation of the connecting rod, therefore, the worker can conveniently change the angle of the herringbone ladder, and the effect of convenient movement is achieved.
本发明涉及纸箱打包技术领域，且公开了一种方便移动的人字梯，包括连接杆、铰链、支撑杆和踏板，铰链共有两组，两组铰链分别设置在连接杆的左右两侧，支撑杆共有四组，两组铰链的底部侧壁分别活动安装有两组支撑杆，踏板共有多组，连接杆的外部分别设置有连接装置、延伸装置、限位装置、固定装置、卡接装置。本发明中，该方便移动的人字梯，工作人员的重心偏向该人字梯的一侧，工作人员可以用腿将该人字梯远离重心的一侧进行偏转，两组连接活动槽均呈圆角矩形，所以当该人字梯进行偏转时，连接活动槽不会对连接杆的旋转进行阻挡，所以能够方便工作人员将该人字梯的角度进行变换，达到了方便移动的效果。
