[0064] The technical scheme in the utility model, by setting the first sliding cooperation structure 3 and the second sliding cooperation structure 4, realize the sliding of bearing table 22 in second direction and third direction, satisfy the basic requirement of image sensor, specifically, the first sliding cooperation structure 3 includes first cooperation part 32 and first rolling part 31, the second sliding cooperation structure 4 includes second cooperation part 42 and second rolling part 41, so that under the action of magnetic force structure 5, cooperation part and rolling part can be closely matched, there is no gap, so that the image sensor can be limited in second direction and third direction.This scheme is simple in structure, reduces the dimensional accuracy requirement of structure, improves anti-shake assembly precision, and effectively improves the deflection of picture.

[0065] It should be noted that the rolling part can be a needle, a roller, a roller and the like, which are all devices that use rolling motion to transmit force and reduce friction.

[0066] In the specific embodiment of the utility model, please refer to Figures 3 to 5The first rolling part 31 comprises a first mounting base 311 and a first ball 312. The first mounting base 311 is arranged on the shell 1 or the connecting piece 21. The first mounting base 311 is provided with a first groove 3111 extending in the second direction on the side of the connecting piece 21 or the shell 1. The first ball 312 is closely arranged in the first groove 3111. Part of the first ball 312 protrudes from the first groove 3111. The first matching part 32 comprises a first sliding block 321. The first sliding block 321 is provided with a second groove 3211 extending in the second direction. The groove of the second groove 3211 is oppositely arranged with the groove of the first groove 3111. The second groove 3211 is used to abut the exposed part of the first ball 312. In the process of sliding contact between the first sliding block 321 and the first ball 312, the first ball 312 rolls. Correspondingly, the second rolling part 41 comprises a second mounting base 411 and a second ball 412. The second mounting base 411 is arranged on the bearing table 22 or the connecting piece 21. The second mounting base 411 is provided with a third groove 4111 extending in the third direction on the side of the connecting piece 21 or the bearing table 22. The second ball 412 is closely arranged in the third groove 4111. Part of the second ball 412 protrudes from the third groove 4111. The second matching part 42 comprises a second sliding block 421. The second sliding block 421 is provided with a fourth groove 4211 extending in the third direction. The groove of the fourth groove 4211 is oppositely arranged with the groove of the third groove 4111. The fourth groove 4211 is used to abut the exposed part of the second ball 412. In the process of sliding contact between the second sliding block 421 and the second ball 412, the second ball 412 rolls. In this way, the matching form of the groove and the ball abutting each other does not have a matching gap. The precision requirement of the size of the parts is not high. Only the diameter of the ball is greater than the width of the groove. Therefore, the structure is simple, the assembly precision of the structure is improved, the sliding resistance of the groove sliding matched with the ball is small, and the movement jamming phenomenon of the bearing table 22 is prevented.

[0067] Further, the groove wall opposite in the third direction of the first groove 3111 is outwardly inclined towards the second groove 3211; the groove wall opposite in the third direction of the second groove 3211 is outwardly inclined towards the first groove 3111; the groove wall opposite in the second direction of the third groove 4111 is outwardly inclined towards the fourth groove 4211; the groove wall opposite in the second direction of the fourth groove 4211 is outwardly inclined towards the third groove 4111. It is worth mentioning that the above four schemes can be set up alternatively, or can be set up simultaneously, and the present scheme does not make specific limitation. In this way, compared with the notch of the groove clamping the ball, in the present embodiment, due to the outwardly inclined groove wall, the two sides opposite of the groove wall are in contact with the surface of the ball, so that the force on the groove is more uniform, the stability of the overall structure is improved, and the service life of the structure is increased.

[0068] It should be noted that the present scheme does not limit the specific number of the first mounting seat 311 and the second mounting seat 411. In a preferred embodiment, please refer to Figure 3 and Figure 4 The first mounting seat 311 is provided with four, four first mounting seats 311 are arranged along the circumference of the shell 1 or the connecting piece 21, four first balls 312 corresponding to the first mounting seat 311 are arranged, and four first sliding blocks 321 corresponding to the first mounting seat 311 are arranged; the second mounting seat 411 is provided with four, four second mounting seats 411 are arranged along the circumference of the bearing table 22 or the connecting piece 21, four second balls 412 corresponding to the second mounting seat 411 are arranged, and four second sliding blocks 421 corresponding to the second mounting seat 411 are arranged. In this way, the stress of each mounting seat is more uniform, and the arrangement of more mounting seats can make the stress of each mounting seat smaller, thereby improving the stability of the overall structure. When the above-mentioned embodiment appears a virtual position, that is, a certain first sliding block 321 does not contact the corresponding first ball 312, or a certain second sliding block 421 does not contact the corresponding second ball 412, in another embodiment, the first mounting seat 311 is provided with three, three first mounting seats 311 are arranged along the circumference of the shell 1 or the connecting piece 21, three first balls 312 corresponding to the first mounting seat 311 are arranged, and three first sliding blocks 321 corresponding to the first mounting seat 311 are arranged; the second mounting seat 411 is provided with three, three second mounting seats 411 are arranged along the circumference of the bearing table 22 or the connecting piece 21, three second balls 412 corresponding to the second mounting seat 411 are arranged, and three second sliding blocks 421 corresponding to the second mounting seat 411 are arranged. By reducing the arrangement of one mounting seat, it can be ensured that all balls can be closely matched with the sliding blocks, thereby improving the assembly precision of the structure.

[0069] It should be further noted that the present solution does not limit the specific number of the first balls 312 in the first mounting seat 311. In the above embodiment, the first mounting seat 311 is provided with only one first ball 312, and such a structure is simpler. In other embodiments, the first mounting seat 311 is provided with a plurality of first balls 312, which are closely arranged in the first mounting seat 311 along the extension direction of the first groove 3111. It is worth mentioning that there is a small gap between the plurality of first balls 312 to limit each first ball 312 within a controllable range, allowing the first ball 312 to have a small amount of displacement in the second direction for its own rolling. Such a structure is simple and convenient to install. Moreover, the plurality of first balls 312 can share the load evenly, reducing the force borne by each first ball 312, thereby reducing the load of a single first ball 312 and prolonging the service life of the first mounting seat 311 and the first ball 312. It can be understood that the second mounting seat 411, the second ball 412, and the second slider 421 can adopt the same implementation as described above, and will not be described here.
