The invention relates to the technical field of electric appliance installation equipment, in particular to a lifting device. The lifting shear fork arm comprises at least one shear fork arm unit, each shear fork arm unit comprises a first supporting arm and a second supporting arm, the first supporting arm and the second supporting arm are hinged in a crossed mode to form the shear fork arm unit, and the lifting shear fork arm is characterized by further comprising a restraining shear fork arm which comprises at least one restraining arm unit. The restraint arm unit comprises a first restraint arm and a second restraint arm, and the first restraint arm and the second restraint arm are hinged in a crossed mode to form the restraint arm unit. The restraining arm units and the shear fork arm units are arranged in a staggered mode, the first restraining arm and the second restraining arm are hinged to the corresponding first supporting arm and the second supporting arm respectively, and the device has the advantages of being good in rigidity and high in operation freedom degree, and is simple and compact in structure and convenient to move.

    本发明涉及电器安装设备技术领域,具体涉及一种升降装置。所述升降剪叉臂包括至少一个剪叉臂单元,所述剪叉臂单元包括第一支臂和第二支臂,所述第一支臂与所述第二支臂交叉铰接以形成所述剪叉臂单元,其特征是:还包括约束剪叉臂,所述约束剪叉臂包括至少一个约束臂单元,所述约束臂单元包括第一约束臂和第二约束臂,所述第一约束臂与所述第二约束臂交叉铰接以形成所述约束臂单元;所述约束臂单元与所述剪叉臂单元错位排布,所述第一约束臂和所述第二约束臂分别铰接于对应的所述第一支臂和所述第二支臂上,具有刚度好、运行自由度高的优点,且其结构简单紧凑,便于移动。
