[0038] One embodiment of the present invention relates to a spring of a prism driving device, such as Figure 2 As shown, the reed 4 includes a first movable portion 41, a second movable portion 42 and a reed body 43. The first movable portion 41 and the second movable portion 42 are perpendicular to each other and are respectively connected to the reed body 43. Specifically, the reed body 43 includes a horizontal reed trunk 432 (numbered in the figure) and two vertical reed side portions 431 connected to the two ends of the reed trunk 432. The two reed side portions 431 are connected to the two ends of the reed trunk 432 or are integrally formed with the reed trunk 432. There are at least two first movable portions 41 and they are respectively connected to the two reed side portions 431. The second movable portion 42 is connected to the reed trunk 432. The first movable portion 41 and the second movable portion 42 can be extended or rotated perpendicular to each other along the reed trunk 432.

[0039] exist Figure 2 In the embodiment shown, the reed trunk 432 is a rectangular strip as a whole, and the reed side portions 431 are arranged on both sides of the reed trunk 432. The two reed side portions 431 are parallel to each other and perpendicular to the reed trunk 432. The two reed side portions 431 are fixedly connected to both sides of the reed trunk 432 and form an inverted "n" shape with the reed body 43. However, it should be understood that the first movable portion 41 can also be directly connected to both ends of the reed trunk 432, that is, the function of the first movable portion 41 can be realized without the need to provide two reed side portions 431, that is, the function of the carrier 2 being able to rotate relative to the base 8 along the Y axis after being connected to the first movable portion 41 is realized.

[0040] Optionally, the positional relationship between the two reed side portions 431 and the reed trunk 432 can be adjusted. For example, the two reed side portions 431 and the reed trunk 432 can be integrally formed into an “I” shape, or arranged into other shapes.

[0041] Optionally, the two reed side portions 431 may be of the same shape or of different shapes, as long as the first movable portion 41 can be connected to the reed trunk 432. In the embodiment shown in the figure, the two reed side portions 431 are symmetrical structures, both of which are rectangular strips perpendicular to the same side of the reed trunk 432, and the upper and lower ends of the two reed side portions 431 extend outward to form two connecting ends 4311, which are used to respectively connect the two ends of the first movable portion 41.
