Moreover, for the disassembly and assembly between the second shell 120 and the first shell 110, the maintenance personnel can complete the disassembly and assembly only by one hand, and the disassembly and assembly efficiency is improved. The lamp mounting body can be a wall body, a ceiling or a lamp mounting bracket. The receiving groove 202 may be formed in the second housing 120, or in the separating elastic member 210, for example, when the receiving groove 202 is located in the second housing 120, the receiving groove 202 is used to receive a portion of the separating elastic member 210, so that the first housing 110 and the second housing 120 are clamped; when the receiving groove 202 is located on the separating elastic member 210, the receiving groove 202 is used for receiving a portion of the second housing 120, and is also used for facilitating the clamping connection between the first housing 110 and the second housing 120.

In this embodiment, the first elastic plate 212 serves as a connecting plate of the separating elastic member 210, so that the second elastic plate 214 and the third elastic plate 216 are fixed to the first housing 110. The second elastic plate 214 and the third elastic plate 216 are connected to each other, the receiving groove 202 is formed at a connection position of the second elastic plate 214 and the third elastic plate 216, and an opening of the receiving groove 202 faces the second housing 120, so that the receiving groove 202 receives a portion of the second housing 120 therein, thereby facilitating the engagement between the first housing 110 and the second housing 120. Both the second elastic plate 214 and the third elastic plate 216 are abutted against the second housing 120, so that the surface of the second elastic plate 214 and the surface of the third elastic plate 216 are used as the side walls of the receiving groove 202, which is convenient for the receiving groove 202 to receive the part of the separating elastic element 210 or the part of the second housing 120, and is also convenient for the second elastic plate 214 and the third elastic plate 216 to clamp the part of the separating elastic element 210 or the part of the second housing 120, thereby further improving the clamping stability between the second housing 120 and the first housing 110.

In this embodiment, the fourth elastic plate 218 and the first elastic plate 212 are disposed obliquely to each other, the fourth elastic plate 218 and the second elastic plate 214 are further disposed obliquely to each other, and a distance between the fourth elastic plate 218 and the second casing 120 is gradually increased in a direction toward the first elastic plate 212, so that a distance between an end of the fourth elastic plate 218 close to the first elastic plate 212 and a side wall of the second casing 120 is greater than a distance between an end of the fourth elastic plate 218 close to the second elastic plate 214 and a side wall of the second casing 120. In this way, after the separation pushing and pulling element 220 separates the separation elastic element 210 from the second casing 120, the second casing 120 is rotated toward the first elastic plate 212, so that the first locking protrusion 130 slides on the fourth elastic plate 218, which facilitates the rotation and detachment between the second casing 120 and the first casing 110, that is, the first locking protrusion 130 on the second casing 120 only needs to be rotated out of the accommodating slot 202, and the fourth elastic plate 218 can be rotated automatically, thereby reducing the acting force for rotating the second casing 120, reducing the work on the second casing 120 during detachment, and further facilitating the detachment between the second casing 120 and the first casing 110. In another embodiment, first resilient plate 212, second resilient plate 214, third resilient plate 216, and fourth resilient plate 218 are integrally formed.

In this embodiment, the separating pushing and pulling member 220 is used for pushing the separating elastic member 210, so that the separating elastic member 210 is separated from the first blocking protrusion 130. The push-off slope 222 corresponds to the receiving groove 202, and the push-off slope 222 is inclined with respect to the separation elastic member 210. Thus, during detachment, in the direction in which the second housing 120 rotates relative to the first housing 110, the distance between the push-away slope 222 and the separation elastic member 210 gradually increases, at this time, the separation elastic member 210 slides on the push-away slope 222, so as to continuously bounce the separation elastic member 210 during rotation, so as to continuously increase the distance between the separation elastic member 210 and the second housing 120, thereby facilitating the first blocking protrusion 130 to escape from the receiving groove 202 of the separation elastic member 210, and further facilitating detachment between the second housing 120 and the first housing 110.
