Furthermore, referring to fig. 3 and 7, the pressing portion 384 is convexly disposed at the side of the buckle 381 of the key 380, and the pressing portion 384 is exposed out of the key mounting groove 351 and the connecting seat 350, so that the user can press the pressing portion 384 to drive the key 380 to move, and the operation is convenient and the practicability is high.

In other embodiments, the connecting base 350 and the base 100 can be connected by a screw or a screw fastener, instead of the detachable clamping manner.

In another embodiment of the present invention, referring to fig. 1, the connection socket 350 includes a connection housing 355, and a connection cover 356 adapted to cover the connection housing 355. The connection housing 355 is installed in the receiving groove 151, and the connection cover 356 is located outside the receiving groove 151. The constant force spring installation cavity 360 and the installation hole 370 are formed between the connection housing 355 and the connection cover 356, an upper end opening of the installation hole 370 extends to the top of the connection housing 355, and two key installation grooves 351 are formed at opposite sides of the connection housing 355. The connecting socket 350 is configured in a combination manner of the connecting shell 355 and the connecting cover 356, so that the connecting socket 350 can be conveniently processed, and meanwhile, the bracket 310 and the constant force spring 330 can be conveniently mounted on the connecting shell 355, so that the production and assembly are convenient.

Specifically, the connecting shell 355 may be fixedly connected to the connecting cover 356 by snapping, screwing, bonding, or the like.

In another embodiment of the present invention, referring to fig. 8, a battery 102 is further disposed in the inner cavity 101, and the battery 102 is electrically connected to the driving member 210 for providing electric energy to the driving member 210.

Referring to fig. 8, a circuit board 103 is further disposed in the inner cavity 101, and the battery 102 and the driving member 210 are electrically connected to the circuit board 103. In this embodiment, circuit board 103 can adopt integrated chip to set up according to the actual production needs, because circuit board 103 belongs to technical modeling and ripe technique among the prior art, so to circuit board 103 how control (window) curtain switching device work reason should be known and can master for technical staff in the field of the art, so the utility model discloses it is no longer repeated here to its control principle.

The rest of this embodiment is the same as the first embodiment, and the unexplained features in this embodiment are explained by the first embodiment, which is not described herein again.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of the ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, its framework form can be nimble changeable, can derive series of products. But merely as a matter of simple deductions or substitutions, should be considered as belonging to the scope of patent protection of the present invention as determined by the claims submitted.
