请参阅图1与图2所示，由图中可清楚看出，本发明设置有传动组1、第一传动轮2、第二传动轮3与座体组4，其中：
该传动组1具有轴杆11以及位移座12，轴杆11上设置有限位键111，位移座12设置有贯穿位移座12两侧的穿孔121，位移座12于穿孔121的内壁上设置有键槽122，键槽122平行于穿孔121，而轴杆11穿设于位移座12的穿孔121内，并使限位键111位于键槽122内，再者，位移座12表面系并排设置有第一外螺纹123与第二外螺纹124，第一外螺纹123与第二外螺纹124的轴向平行于穿孔121，第二外螺纹124的导程大于第一外螺纹123的导程。
该第一传动轮2具有第一内螺纹21，第一内螺纹21螺合于传动组1的第一外螺纹123；
该第二传动轮3具有第二内螺纹31，第二内螺纹31螺合于传动组1的第二外螺纹124；
该座体组4设置有基座41，以及基座41内所设置的轴承42，而传动组1的轴杆11两端固定于基座41，第一传动轮2与第二传动轮3系受轴承42承托定位。
请参阅图2与图3所示，由图中可清楚看出，由于座体组4的轴承42限制了第一传动轮2与第二传动轮3位移，让第一传动轮2与第二传动轮3仅能依轴承42枢转，且轴杆11的限位键111限制了位移座12仅能横向位移无法枢转，故第一传动轮2转动时，第一传动轮2的第一内螺纹21会推动第一外螺纹123，使位移座12于轴杆11上位移，而于位移座12移动的同时，第二外螺纹124会推动第二传动轮3的第二内螺纹31，俾使第二传动轮3依轴承42枢转，凭借第二外螺纹124的导程大于第一外螺纹123的导程，使第二传动轮3转动速率低于第一传动轮2，以达到减速的目的。
请参阅图4与图5所示，由图中可清楚看出，本发明第二实施例与前述的第一实施例差异在于，该传动组5的位移座52表面所设置的第一外螺纹523与第二外螺纹524为呈重叠状，同样的，第一外螺纹523与第二外螺纹524的轴向平行于穿孔521，第二外螺纹524的导程大于第一外螺纹523的导程。
请参阅图1与图6所示，由图6中可清楚看出，本发明第三实施例与前述的第一实施例差异在于，该第三实施例传动组6的位移座62，其第二外螺纹
624为凸螺纹，第二传动轮8的第二内螺纹81为凹螺纹，而第一实施例传动组1的位移座12，其第二外螺纹124为凹螺纹，第二传动轮3的第二内螺纹31为凸螺纹，且第三实施例同样可以达到相同于第一实施例减速的功效；由前述可得知，本案传动组1、6的第二外螺纹124、624与第二传动轮2、8的第二内螺纹21、81，只要为凹螺纹以及凸螺纹相互配合即可，并不限定一定是要外螺纹或一定是要内螺纹才可，传动组1、6的第一外螺纹123、623与第一传动轮2、7的第一内螺纹21、71也同。
是以，本发明为可解决现有的问题与缺失，其关键技术在于，本发明利用限制位移座12、52仅能横向位移，并于位移座12、52上设置不同导程的第一外螺纹123、523与第二外螺纹124、524，让第一传动轮2于转动时，利用第一内螺纹21推动第一外螺纹123、523使位移座12、52横向位移，并利用位移座12、52的横向位移，使第二外螺纹124、524推动第二内螺纹31，让第二传动轮3转动，且第二传动轮3转动速率低于第一传动轮2，以达到减速的目的，并可简化减速装置，方便维修且降低使用成本。
