我们知道,平面连杆机构可以用于产生近似停歇运动,文献等在这方面都作了介绍和研究。平面连杆停歇机构在工程实际中也得到了应用。相比之下,空间停歇机构几乎没见到实际应用。原因是多方面的,主要是工程师对空间停歇机构的潜在用途和优点很少了解;由于空间连杆机构运动复杂, We know that the planar linkage mechanism can be used to generate approximate stop motion, literature and so on are introduced and studied in this regard. Plane linkage rest mechanism in engineering practice has also been applied. In contrast, almost no practical application of space to rest agencies. There are many reasons for this, mainly due to the fact that engineers rarely understand the potential uses and advantages of a space breakout facility. Due to the complicated movement of space linkages,
