For another example, the third side plate may be provided to be simultaneously snap-coupled to the first side plate and the second side plate, or the like, in addition to being pivotally coupled to the second side plate.

Referring now to fig. 2-3, 9-10, a specific embodiment of the mount 40 will be described.

In one embodiment, as shown in fig. 2-3 and 9-10, the mounting block 40 is provided with two oppositely disposed first mounting portions 44. Correspondingly, two opposite side walls of the housing 10 are respectively provided with a second mounting portion 17, and the second mounting portion 17 can be in fit connection with the first mounting portion 44 so as to realize detachable connection of the housing 10 to the mounting seat 40.

Specifically, the mount 40 includes a first riser 41, a second riser 42, a bottom plate 43, and a stop 46. The first riser 41 is provided with a first mounting structure 411, and the mounting seat 40 is fixedly mounted near the blind 200 by the first mounting structure 411. In this application, the first mounting structure 411 is a countersunk hole, and a plurality of countersunk holes are formed in the first riser 41 in an array, and the first riser 41 can be fixedly connected to a wall or a column near the blind 200 by passing a screw through the countersunk holes. Two second risers 42 are provided, the two second risers 42 are disposed opposite to each other and are respectively connected to two side edges of the first riser 41, and a first mounting portion 44 is disposed on an inner side of each second riser 42. Preferably, the two second risers 42 are integrally formed with the first riser 41 and are formed by bending both side edges of the first riser 41. The bottom plate 43 is connected to the bottom of the first riser 41, and extends horizontally from the bottom of the first riser 41, and the bottom of the housing 10 can abut against the bottom plate 43 when mounted.

Through setting up spout 423, be favorable to fixing a position casing 10, improve the connection stability of installation convenience and casing 10. By arranging the stop block 46, the key 45 and the buckle can be enclosed between the stop block 46 and the second vertical plate 42, so that the structural stability is improved.

Of course, the specific arrangement of the mounting seat 40 is not unique, and a person skilled in the art may adjust the mounting seat to be suitable for a more specific application scenario.

For example, while the mount 40 is described in connection with having the first riser 41, the second riser 42, the bottom plate 43, this is merely a preferred embodiment, and in other embodiments, one skilled in the art may optionally omit the at least one structure, such as omitting the bottom plate 43 or omitting the at least one second riser 42, etc. For another example, the first mounting structure 411 may be provided on the first riser 41 in addition to the second riser 42, and the number thereof may be one, two, or more. Accordingly, the position of the second mounting portion 17 on the housing 10 needs to be adjusted. In addition, the mounting seat 40 is not necessary, and in other embodiments, a connection structure, such as a lug or a suction cup with a connection hole, may be directly disposed on the housing 10, so as to directly and fixedly connect the housing 10 to a wall or glass.

For another example, the specific arrangement of the first mounting portion 44 and the second mounting portion 17 may be adjusted. For example, the setting positions of the buckle and the rack may be interchanged, or one of the first mounting portion 44 and the second mounting portion 17 is a clamping block, and the other is a clamping groove, where the clamping block can be slidably clamped.

For another example, the first mounting structure 411 may be a suction cup, in addition to the counter bore, by which the first riser 41 may be mounted on a glass or smooth surface.

For another example, the setting of the key 45 is not necessary, and one skilled in the art can select whether to set based on a specific application scenario. In addition, when the key 45 is set, the key 45 may be set separately from the buckle, so long as the key 45 can drive the buckle to rotate when the key 45 is pressed.

For another example, the setting of the stopper 46 is not necessary, and one skilled in the art may select according to the application scenario.

For another example, besides the elastic pivoting through the torsion spring, the same function can be realized through the compression spring, and at this time, two ends of the compression spring can be abutted against the lower side surface of the buckle and the bottom of the first mounting groove 421.

For another example, the chute 423 is not necessarily provided, and in other embodiments, the chute 423 may be omitted.
