The invention discloses a jack with a rotatable plug structure, and belongs to the technical field of jacks. Comprising an ejector head part, a supporting arm part, a base and a lead screw, the upper end and the lower end of the supporting arm part are hinged to the ejector head part and the base respectively, the supporting arm part is of a movable parallelogram structure, the lead screw is installed in the supporting arm part, and rotation of the lead screw is used for driving the supporting arm part to move. The device is characterized in that the ejector head component comprises a rotary ejector head, a pin and a supporting plate, the supporting plate is hinged to the upper end of the supporting arm component, and the rotary ejector head is hinged to the supporting plate through the pin. The automobile jack has the advantages that lateral tension applied to the jack by an automobile is relieved through autorotation of the rotary jacking head, the problem of distortion of the jack in the prior art is solved, the thickness of selected materials is reduced, the manufacturing cost is reduced, and the competitiveness is improved.
一种具有可旋转顶头结构的千斤顶,属于千斤顶技术领域。包括顶头部件、支臂部件、底座、丝杠,所述支臂部件的上下两端端部分别与顶头部件以及底座实现铰接,所述的支臂部件为一可活动的平行四边形结构,所述的丝杠安装于支臂部件中,丝杠的转动用于驱动支臂部件运动,从而调节顶头部件与底座的相对位置,特点是:所述的顶头部件包括旋转顶头、销子、支撑板,所述的支撑板与支臂部件的上端端部铰接,所述的旋转顶头通过销子铰接在支撑板上。优点:其通过旋转顶头的自转来缓解汽车施加在千斤顶上的侧向拉力,解决现有技术中千斤顶发生的扭曲状态,同时减少选材厚度,降低制造成本,提高竞争力。
