上面的描述中闡述了很多具體(ti)細節以(yi)便于充(chong)分理(li)解本實(shi)用新(xin)型(xing)(xing)，但是，本實(shi)用新(xin)型(xing)(xing)還可以(yi)采(cai)用其他(ta)不同于在(zai)此(ci)描述的其他(ta)方式來實(shi)施，因(yin)此(ci)，不能理(li)解為對本實(shi)用新(xin)型(xing)(xing)保(bao)護范圍的限制。

總(zong)之，本(ben)(ben)實(shi)用新型(xing)雖然列舉了上述優選實(shi)施(shi)方式，但是應該(gai)說(shuo)明，雖然本(ben)(ben)領域的技(ji)術人員(yuan)可以進行各種變化和改型(xing)，除非這樣(yang)的變化和改型(xing)偏離(li)了本(ben)(ben)實(shi)用新型(xing)的范(fan)圍，否則都應該(gai)包括在本(ben)(ben)實(shi)用新型(xing)的保護范(fan)圍內。
