观点正确

the invention disclsoes a ..device, which comprises an upper opening equipment arranged at top, a lower opening equipment arranged at bottom, a left opening equipment arranged at left side, and a right opening equipment arranged at right side.

也建议去掉逗号，这样指代device明确，没有必要加上逗号。而且如果真的觉得从句过于长的话，可以写成两个分句。
