More particularly, the retaining portion 141 in a first receiving groove 131 can be restricted or limited by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane, so that the retaining member 14 can be moved upwardly (as shown in
Referring to
Therefore, the first fixing portion 151 and the second fixing portion 154 of the elastic member 15 are fixed on the seat portion 13, so that the bonding strength between the elastic member 15 and the seat portion 13 can be increased so as to prevent the pulling member 2 from being separated from the sliding assembly 1.
Moreover, the elastic coefficient and the elastic force provided by the elastic portion 152 can be increased by matching “the elastic member 15 having a first fixing portion 151 fixed on the seat portion 13, an elastic portion 152 extending from the first fixing portion 151, and an abutting portion 153 extending from the elastic portion 152 for abutting against the retaining member 14” and “the thickness h2 of the elastic portion 152 being smaller than the thickness h1 of the first fixing portion 151”. Therefore, the elastic portion 152 can avoid causing elastic fatigue and plastic deformation, so that the usage life of the elastic member 15 can be increased.
In conclusion, no matter how the adjustable angle θ is adjusted or changed, the retaining portion 141 can be restricted by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ.
The aforementioned descriptions merely represent the preferred embodiments of the present disclosure, without any intention to limit the scope of the present disclosure which is fully described only within the following claims. Various equivalent changes, alterations or modifications based on the claims of the present disclosure are all, consequently, viewed as being embraced by the scope of the present disclosure.
