One end of the elastic piece can be connected with the second shell 2, the other end of the elastic piece can be connected with the movable plate 3, and the elastic piece can drive the movable plate 3 to move relative to the second shell 2 through elasticity generated by deformation.

For example, as shown in fig. 7, in the case of the first state, the elastic member may be in a compressed state, where there is a difference in height between the movable plate 3 and the support surface 11, and the movable plate 3 may be accommodated in the first housing 1. In the case of the second state, as shown in fig. 8, the elastic member may be in an extended state, in which the movable plate 3 may move to be in the same plane as the supporting surface 11 under the elastic force of the elastic member.

In this embodiment, the driving component 4 can achieve the purpose of driving the movable plate 3 to move to be in the same plane with the supporting surface 11 through the interaction of elastic force.

Alternatively, in some embodiments, the elastic member is a spring, and the target member is provided with a second guide post 8, and the spring is connected to the target member through the second guide post 8, where the target member includes at least one of the second housing 2 and the movable plate 3.

As shown in fig. 9, the elastic member may be a spring, and the second casing 2 and the second guide post 8 on the movable plate 3 may be inserted into a hollow area of the spring, and the spring may be compressed or stretched along the second guide post 8, so that when the movable plate 3 moves relative to the second casing 2 to be in the same plane with the supporting surface 11, the displacement of the movable plate 3 in other directions is limited, and the position accuracy of the movable plate 3 is effectively ensured.

It will be appreciated that the second guide post 8 may also be provided only on the second housing 2 or the movable plate 3, for example, the second housing 2 is provided with the second guide post 8, the second guide post 8 is inserted into a hollow area at one end of the spring, and the other end of the spring may be fixedly connected with the movable plate 3.

In some examples, the number of the springs may be plural, as shown in fig. 9, the plural springs are disposed between the second housing 2 and the movable plate 3 at intervals, and the number and positions of the second guide posts 8 disposed on the second housing 2 and/or the movable plate 3 may be matched with the number of the springs.

Optionally, referring to fig. 7 and 8, in some embodiments, two ends of the movable plate 3 are respectively provided with an inclined plane, and an orthographic projection of the first side on a plane of the second housing 2 is located within an orthographic projection of the second side on the plane of the second housing 2, where the first side is a side of the movable plate 3 away from the second housing 2, and the second side is a side of the movable plate 3 close to the second housing 2;

the first end of the supporting surface 11 is provided with parallel inclined surfaces with the same inclination corresponding to the inclined surfaces of the movable plate 3;

the second end of the second shell 2 is provided with parallel inclined planes with the same inclination corresponding to the inclined planes of the movable plate 3;

under the second state, the movable plate 3 is driven by the driving component 4 to be in the same plane with the supporting surface 11, the inclined plane of the first end is opposite to the inclined plane of one end of the movable plate 3, and the inclined plane of the second end is opposite to the inclined plane of the other end of the movable plate 3.

As shown in fig. 7 and 8, both ends of the movable plate 3 are respectively provided with inclined surfaces, and the section of the movable plate 3 is in a regular trapezoid shape. The first end of the supporting surface 11 is provided with parallel inclined surfaces with the same inclination corresponding to the inclined surfaces of the movable plate 3, in other words, the inclined surfaces of the first end of the supporting surface 11 can be matched with the inclined surfaces of the left end of the movable plate 3. The second end of the second housing 2 is provided with parallel inclined planes having the same inclination corresponding to the inclined planes of the movable plate 3, in other words, the inclined planes of the second end of the second housing 2 may be matched with the inclined planes of the right end of the movable plate 3.

In the case of the second state, the inclined plane of the first end of the supporting surface 11 is disposed opposite to the inclined plane of one end of the movable plate 3, and the inclined plane of the second end of the second housing 2 is disposed opposite to the inclined plane of the other end of the movable plate 3, for example, the inclined plane of the first end of the supporting surface 11 may abut against the inclined plane of the left end of the movable plate 3, and the inclined plane of the second end of the second housing 2 may abut against the inclined plane of the right end of the movable plate 3. On the one hand, the matching of the inclined planes can play a certain limiting role, and further ensure that the movable plate 3 and the supporting surface 11 can be positioned on the same plane. On the other hand, when the first housing 1 slides from the second state to the first state relative to the second housing 2, the inclined surface can apply a downward force to the movable plate 3, so that the movable plate 3 presses the elastic member, and thus, a height difference exists between the movable plate 3 and the supporting surface 11, and further, smooth sliding of the first housing 1 to the first state relative to the second housing 2 is ensured.
