The lifting appliance comprises a base body and an expansion mechanism arranged on the base body, the expansion mechanism comprises an expansion core and an expansion sleeve, the expansion sleeve is connected with the base body, the expansion core is movably installed in the expansion sleeve in the longitudinal direction of the expansion sleeve, and the end, facing the base body, of the expansion core is connected with a pull rod used for controlling the position of the expansion core. The pull rod is movably installed on the base body in a penetrating mode in the longitudinal direction of the base body, the base body is used for assisting in guiding the pull rod to move in the longitudinal direction, the expansion sleeve expands or resets under the action of the expansion core, and when the expansion sleeve resets, the expansion sleeve can stretch into an inner hole of the differential mechanism; when the expansion core forces the expansion sleeve to expand, the expansion sleeve is tightly attached to an inner hole of the differential mechanism, and therefore the position between the expansion core and the differential mechanism is fixed. In this way, the differential mechanism can be lifted easily, the weight of the lifting appliance is greatly reduced, and the lifting appliance is light, flexible and easy to operate.

    本发明公开了一种用于差速器的吊具,包括:基体和设置在基体上的胀紧机构,胀紧机构包括胀芯和胀套,胀套与基体连接,胀芯沿胀套的纵向可移动的安装在胀套内,胀芯朝向基体的一端连接有用于控制胀芯位置的拉杆,拉杆沿基体的纵向可移动的贯穿的安装在基体上,基体用于辅助引导拉杆的纵向移动,胀套在胀芯的作用下胀开或复位,当胀套复位时,胀套可伸入差速器的内孔内;当胀芯迫使胀套胀开时,胀套与差速器的内孔紧紧贴合,从而固定住胀芯与差速器之间的位置;通过上述方式,本发明能够轻便的将差速器吊起,大大减少吊具的重量,轻巧灵活,操作简单。
