The invention provides a power switching lifting device. The power switching lifting device comprises a first transmission shaft, a fixing frame, a first pulley and a second pulley. The first pulley, the second pulley and the first transmission shaft are rotationally mounted on the fixing frame, and the first transmission shaft penetrates through the first pulley and the second pulley; a first spline and a second spline are arranged at the two ends of the first transmission shaft respectively, the first transmission shaft is driven to move and change into a first state and a second state on the fixing frame in the axis direction, and in the first state, the first spline is bonded with the first pulley, and the second spline is bonded with the second pulley; and in the second state, the first spline is bonded with the first pulley, and the second pulley and the first transmission shaft can rotate relatively. The invention further provides an auxiliary standing device for the animals. The auxiliary standing device comprises the hoisting piece and the power switching hoisting device. A worker in a laboratory only needs to adjust and switch the first transmission shaft to enter the first state or the second state, and then the two hoisting and pulling pieces or the single hoisting and pulling piece can be adjusted at the same time.
本申请提供了一种动力切换吊升装置,包括第一传动轴、固定架、第一滑轮和第二滑轮;第一滑轮、第二滑轮和第一传动轴均转动安装在固定架上,第一传动轴穿设于第一滑轮和第二滑轮;第一传动轴两端分别设有第一花键和第二花键,第一传动轴被驱动后在固定架上沿轴线方向移动变化为第一状态和第二状态,在第一状态下,第一花键与第一滑轮键合,第二花键与第二滑轮键合;在第二状态下,第一花键与第一滑轮键合,第二滑轮和第一传动轴可相对转动。本申请还提供了一种动物辅助站立装置,包括吊拉件和动力切换吊升装置。实验室的工作人员只需要调整切换第一传动轴进入第一状态或者第二状态,就能够同时调整两个吊拉件或者单个吊拉件。
