The matching of the number of sliders 212 with the number of corresponding mounting slots 126 means that: the number of the sliding blocks 212 positioned on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127 is the same as the number of the mounting grooves 126 formed in the inner side surface 121 of the first side plate 127, and the number of the mounting grooves is two; the number of the sliding blocks 212 on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128 is the same as the number of the mounting grooves 126 formed in the inner side surface 121 of the second side plate 128, and the two sliding blocks 212 are in one-to-one correspondence with the two mounting grooves 126. Of course, in other embodiments, the number of the sliding blocks 212 may be less than the number of the mounting slots 126, for example, the number of the sliding blocks 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127 is less than the number of the mounting slots 126 formed on the inner side surface 121 of the first side plate 127, and the number of the sliding blocks 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128 is less than the number of the mounting slots 126 formed on the inner side surface 121 of the second side plate 128. Moreover, the length d1 of the sliding block 212 along the x direction is less than or equal to the length d2 of the mounting groove 126 along the x direction, so that the sliding block 212 can conveniently slide into the sliding groove 125 after penetrating through the mounting groove 126.

The shape of the slider 212 taken by a plane perpendicular to the optical axis O may be a rectangle, a semicircle, or other shapes such as other regular shapes or irregular shapes, as long as the shape of the slider 212 matches the shape of the corresponding chute 125. Specifically, the matching of the shape of the slider 212 and the corresponding chute 125 means: when the section of the sliding groove 125 formed in the inner side surface 121 of the first side plate 127, which is cut by a surface perpendicular to the optical axis O, is rectangular, the section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127, which is cut by a surface perpendicular to the optical axis O, is also rectangular; when the section of the sliding groove 125 formed in the inner side surface 121 of the second side plate 128, which is cut by a surface perpendicular to the optical axis O, is rectangular, the section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128, which is cut by a surface perpendicular to the optical axis O, is also rectangular; when the cross section of the sliding groove 125 formed in the inner side surface 121 of the first side plate 127, which is cut by a surface perpendicular to the optical axis O, is semicircular, the cross section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127, which is cut by a surface perpendicular to the optical axis O, is also semicircular; when the cross section of the sliding groove 125 formed in the inner side surface 121 of the second side plate 128, which is cut by a surface perpendicular to the optical axis O, is a semicircle, the cross section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128, which is cut by a surface perpendicular to the optical axis O, is also a semicircle, and so on, which is not listed here.

Referring to fig. 7, in the present embodiment, the shape of the slider 212 cut by a plane perpendicular to the optical axis O is an irregular shape, and the irregular shape is enclosed by a straight line and an arc line to form a closed "D" shape, wherein the shape of the outer wall of the slider 212 cut corresponds to the arc portion of the "D" shape. The matching of the shape of the slider 212 with the shape of the corresponding runner 125 means: the curvature of the arc corresponding to the inner wall of the sliding groove 125 is the same as that of the arc corresponding to the outer wall of the sliding block 212. In this manner, the slider 212 and the chute 125 can be better fitted.

In the z direction, the opposite ends of the slider 212 abut the opposite ends of the inner wall of the chute 125. Specifically, when the slider 212 is installed in the sliding groove 125, in the z direction, the two ends of the opposite side of the slider 212 corresponding to the first side plate 127 are abutted against the two ends of the opposite side of the inner wall of the sliding groove 125 on the inner side 121 of the first side plate 127, and the two ends of the opposite side of the slider 212 corresponding to the second side plate 128 are abutted against the two ends of the opposite side of the inner wall of the sliding groove 125 on the inner side 121 of the second side plate 128, so that the movement of the slider 212 in the z direction is limited, the slider 212 is prevented from shaking or inclining (tilt) in the z direction, and the imaging quality of the first lens module 20 is ensured not to.

Referring to fig. 4 to 6, in the present embodiment, the prism assembly 40, the second lens module 30 and the first lens module 20 are sequentially disposed in the accommodating space 14 along the optical axis O direction. Wherein, the prism assembly 40 and the second lens module 30 are fixedly disposed on the bearing surface 111 of the substrate 11; the sliding block 212 is inserted into the sliding groove 125 after passing through the mounting groove 126, so that the sliding block 212 is slidably disposed in the sliding groove 125, and the first lens module 20 is slidably connected to the side plate 12. The sliding block 212 is fixedly connected to the main body 211, and when the sliding block 212 slides in the sliding slot 125, the relative distance between the first lens module 20 and the second lens module 30 changes.
