The invention discloses a screw push-pull type disassembly and assembly tool, which relates to the technical field of mechanical disassembly and assembly, and comprises a screw push-pull power device, a shell, an expansion device, a universal disassembly and assembly device, a support device, a speed reducer and a belt. According to the universal disassembling and assembling device, through bending deformation of the universal coupling and the reset spring, the bolt disassembling head can adapt to disassembling of bolts at different positions, and meanwhile the bolt disassembling head can be replaced according to the actual size of the automobile tire bolt. According to the expansion device, stretching and retracting of a first expansion sliding rail are achieved through a sine mechanism, then the distance between a first expansion connecting rod and a second expansion connecting rod is adjusted through rotation of an expansion screw, vertical inclination of the whole device is achieved, and therefore the expansion distance adjusting function is achieved. According to the speed reduction device, the transmission ratio is changed through a speed change mechanism, and then one-way torque transmission and change of the torque transmission direction are achieved through a direction-variable clutch mechanism.

    本发明公开了一种螺杆推拉式拆装工具,涉及机械拆装技术领域,包括螺杆推拉动力装置、外壳、扩展装置、万向拆装装置、支撑装置、减速装置、皮带。万向拆装装置,通过万向联轴器和复位弹簧的弯曲变形,可以使螺栓拆卸头适应不同位置螺栓的拆卸,同时螺栓拆卸头可以根据实际的汽车轮胎螺栓的大小进行更换。扩展装置,通过正弦机构实现第一扩展滑轨的伸缩,然后通过扩展螺杆的转动来调节第一扩展连杆与第二扩展连杆的距离,实现整个装置的上下倾斜,从而实现展开调距功能。减速装置,通过变速机构实现传动比的变化,随后通过可变向离合机构,实现扭矩单向传递以及扭矩传递方向的改变。
