The spring fixing part protrudes from a trim base of the trim assembly and adapted to be inserted into a containing part of the engaged assembly. The first contact spring is connected to the spring fixing part and adapted to abut on an inner wall of the containing part. The first contact spring includes a connecting part, an abutting part, and an extending arm. The connecting part is connected to the spring fixing part. The abutting part bends from a terminal of the connecting part and extends to form a first abutting face. The extending arm has a second abutting face and extends from a side of the first abutting face. ## Claims ### Claim 1 A trim assembly, adapted to be mounted in an engaged assembly, comprising: a spring fixing part; and a first contact spring connected to the spring fixing part and adapted to abut on an inner wall of a containing part of the engaged assembly, the first contact spring comprising: a connecting part connected to the spring fixing part; an abutting part bending from a terminal of the connecting part and extending to form a first abutting face, wherein the abutting part comprises an end terminal bending part bending towards the spring fixing part from an end terminal of the abutting part; and an extending arm having a second abutting face extending from a side of the first abutting face, wherein the second abutting face extends along a horizontal direction and comprises a smooth face. ### Claim 2 (depends on 1) The trim assembly of claim 1, wherein a first angle is formed between the connecting part and the abutting part, and a degree of the first angle is related to a frictional force between the first contact spring and the inner wall. ### Claim 3 (depends on 1) The trim assembly of claim 1, further comprising a second contact spring disposed on the spring fixing part and contacting the inner wall, wherein a structure of the second contact spring corresponds to that of the first contact spring. ### Claim 4 (depends on 3) The trim assembly of claim 3, wherein when the first contact spring and the second contact spring are connected to the spring fixing part, a position of the first contact spring on the spring fixing part and a position of the second contact spring on the spring fixing part are symmetrical to each other. ### Claim 5 (depends on 4) The trim assembly of claim 4, wherein the extending arm of the first contact spring and the extending arm of the second contact spring extend along opposite directions. ### Claim 6 (depends on 4) The trim assembly of claim 4, wherein the extending arm of the first contact spring and the extending arm of the second contact spring extend along a same direction. ### Claim 7 (depends on 1) The trim assembly of claim 1, wherein the first contact spring is made of an elastic material, and when the trim assembly is mounted in the engaged assembly, a free space exists between the extending arm and the spring fixing part. ### Claim 8 (depends on 1) The trim assembly of claim 1, wherein the trim assembly is applied to a lighting fixture. ### Claim 9 A spring structure for a trim assembly adapted to be mounted into a containing part of an engaged assembly, the spring structure comprising: a first contact spring adapted to abut on an inner wall of the containing part, the first contact spring comprising: a connecting part connected to a spring fixing part of the trim assembly; an abutting part bending from a terminal of the connecting part and extending to form a first abutting face, wherein the abutting part comprises an end terminal bending part bending towards the spring fixing part from an end terminal of the abutting part; and an extending arm having a second abutting face extending from a side of the first abutting face, wherein the second abutting face extends along a horizontal direction and comprises a smooth face. ### Claim 10 (depends on 9) The spring structure of claim 9, wherein a first angle is formed between the connecting part and the abutting part, and a degree of the first angle is related to a frictional force between the first contact spring and the inner wall. ### Claim 11 (depends on 9) The spring structure of claim 9, further comprising a second contact spring disposed on the spring fixing part and contacting the inner wall, wherein a structure of the second contact spring corresponds to that of the first contact spring. ### Claim 12 (depends on 11) The spring structure of claim 11, wherein when the first contact spring and the second contact spring are connected to the spring fixing part, a position of the first contact spring on the spring fixing part and a position of the second contact spring on the spring fixing part are symmetrical to each other. ### Claim 13 (depends on 11) The spring structure of claim 11, wherein the extending arm of the first contact spring and the extending arm of the second contact spring extend along opposite directions. ### Claim 14 (depends on 11) The spring structure of claim 11, wherein the extending arm of the first contact spring and the extending arm of the second contact spring extend along a same direction. ### Claim 15 (depends on 9) The spring structure of claim 9, wherein the first contact spring is made of an elastic material, and when the trim assembly is mounted in the engaged assembly, a free space exists between the extending arm and the spring fixing part. ### Claim 16 (depends on 9) The trim assembly of claim 9, wherein the trim assembly is applied to a lighting fixture.
