It should be noted that the above preferred implementation manners are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Without departing from the principle of the present application, those skilled in the art can adjust the above setting manner, so that the present application can be applied to more specific application scenarios.

For example, in a possible implementation manner, although the above-mentioned embodiment is described with the shell 1 including the front shell 11 and the rear shell 12, this structural form is not the only one, and those skilled in the art can understand the specific structure of the shell 1. The structure is adjusted so that the adjusted technical solution is applicable to more specific application scenarios. For example, the housing 1 can also be configured as an integral structure, a split structure up and down, a split structure in left and right, and the like.

As another example, in an alternative embodiment, the pivoting arrangement of the two splints 41 is not unique, and those skilled in the art can specify the two splints 41 on the premise that the two splints 41 can pivot respectively relative to the housing 1. Adjust the setting form. For example, the two splints 41 can be pivotably arranged on opposite sides of the casing 1 through the same rotating shaft. Specifically, taking the orientation shown in FIG. 5 as an example, the second shaft seat 14 can be provided in the middle of the upper edge of the left and right side surfaces of the housing 1, and then the first shaft seat 413 with the two splints 41 on the same side can be connected with a first shaft seat 413 at the same time. The two shaft seats 14 are pivotally connected. More specifically, the two first axle seats 413 on the left side of FIG. The two first shaft seats 413 are pivotally connected to the second shaft seat 14 located in the middle of the upper edge of the right side of the housing 1 through another short shaft.

As another example, in another alternative embodiment, the specific shape of the splint 41 is not constant, and can be adjusted by those skilled in the art. For example, the splint 41 can only include the chuck 411 and the handle 412 positioned at the top of the rotating shaft 5, and omit the handle 412 at the bottom of the rotating shaft 5 used as a free end; for another example, each section of the splint 41 can be set to other shapes, such as The collet 411 is replaced with an L shape, the handle 412 is replaced with an arc, etc.

For another example, in another alternative embodiment, those skilled in the art can adjust the specific arrangement of the above-mentioned power supply assembly 3, as long as the adjusted technical solution can ensure that the device has a power supply assembly 3 and the power supply assembly is a driving mechanism Just power on. For example, the power supply assembly 3 may include a circuit board 32 and a battery compartment, and the battery compartment is used to store dry batteries.

For another example, in another alternative embodiment, the rolling member 42 may be replaced by other parts such as universal balls in addition to the roller. This substitution does not deviate from the principle of the present application, and therefore also falls within the protection scope of the present application.

For another example, in another alternative embodiment, the elastic member 6 can be replaced by other parts besides the torsion spring. In a possible implementation manner, the elastic member 6 may be a compression spring, and the two ends of the compression spring respectively abut between the handle 412 of the splint 41 and the housing 1 .

For another example, on the basis of ensuring that the curtain opening and closing device has a housing 1, a driving roller assembly 2, a power supply assembly 3, and a clamping part 4, and that the clamping part 4 can be pivotally connected to the housing 1, other components in the above-mentioned embodiment Or the structure can be selectively modified or deleted by those skilled in the art. For example, parts such as the rolling member 42 and the elastic member 6 can be deleted, and the accommodation groove 414, the notch 15, the shallow groove 415, the narrowing structure on the side of the housing 1, etc. can be modified or omitted.

Of course, the above alternative implementations, and between the alternative implementations and the preferred implementations can also be used in cross-coordination, so that new implementations can be combined to apply to more specific application scenarios.
