Claim 2: The table according to claim 1 is characterized in that the legs of the table are composed of at least one tube and at least one hinge.
In this way, since the features in Claim 1 are novel and creative (creativity is necessary, otherwise it cannot be authorized), Claim 2, as a subordinate claim, can be limited to the maximum protection scope.
2. All specific technical features must be clearly stated in the claims, and some general advertising words such as "high efficiency" and "omnipotence" cannot be used (unless they are recognized in the technical field). I suggest you write:
Claim 1, a table consists of a base 1, a table top 2 and table legs 3, characterized in that the table legs 3 are arranged on the base 1, the table top 2 is arranged on the table legs 3, and waste paper baskets or garbage bags are installed on the side of the table legs 3 (the waste paper baskets and garbage bags should be part of the table legs 3, otherwise, the front part is composed of the base.
If you are worried that the specific structure described here will cause a small protection range, you can claim that "the table consists of a base 1, a table top 2 and table legs 3, which are characterized in that the table legs 3 are arranged on the base 1, the table top 2 is arranged on the table legs 3, and waste paper baskets or garbage bags are installed on the sides of the table legs 3". Please explain the composition of table legs in claim 2.
I hope the answer will help you.
