[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figure 1-3 The embodiment of the utility model provides a combined zoom lens, including a lens body 1, a zoom ring 2 and a focus ring 4, the zoom ring 2 and the focus ring 4 are rotatably connected to the inside of both sides of the lens body 1 respectively, a support plate 5 is arranged on the right side of the lens body 1, a second fixing block 9 is fixedly connected to the right side wall above the support plate 5, and the second fixing block 9 is fixedly connected to the side wall of the lens body 1, a first gear ring 8 is fixedly sleeved and installed on the outer side wall of the focus ring 4, a first gear 7 is rotatably connected to the inside of the upper end of the support plate 5, and the first gear 7 is meshed with the first gear ring 8. When focusing is performed through the focus ring 4, the first gear 7 is turned so that the first gear 7 can drive the first gear ring 8 to rotate, thereby enabling the focus ring 4 to rotate and perform the focusing operation of the focus ring 4.

[0019] Example 2

[0020] In this embodiment, Figure 1-3 As shown, a first fixed block 6 is fixedly installed on the left side wall below the support plate 5, a mounting seat 12 is rotatably connected to the bottom of the zoom ring 2, the end of the first fixed block 6 is fixedly connected to the side wall of the mounting seat 12, a second gear ring 11 is fixedly sleeved and installed on the outer side wall of the zoom ring 2, a second gear 10 is rotatably connected to the inside of the lower part of the support plate 5, and the second gear 10 is rotatably connected to the second gear ring 11. When focusing, the second gear 10 is rotated to drive the second gear ring 11 to rotate, so that the zoom ring 2 can be conveniently focused.

[0021] Example 3

[0022] In this embodiment, Figure 1-3As shown, a support handle 3 is fixedly installed on the left side wall of the mounting seat 12, and the support handle 3 is L-shaped. When the lens body 1 is in use, the support handle 3 is used for supporting work by hand, which can not only stabilize the position of the lens body 1, but also prevent the focus ring 4 and the zoom ring 2 from being touched, which would cause inaccurate internal focus. The second fixed block 9 is arranged below the first gear ring 8, and the top of the support plate 5 is higher than the position of the second fixed block 9. The zoom ring 2 and the focus ring 4 and their externally connected parts are all made of plastic.

[0023] It should be noted that, in this embodiment, when using a combined zoom lens, Figure 1-3 As shown, when focusing is performed through the zoom ring 2 and the focus ring 4, the second gear 11 and the first gear 7 are respectively moved, so that the second gear 10 drives the second gear ring 11 to rotate, and the first gear 7 can drive the first gear ring 8 to rotate, so that the zoom ring 2 and the focus ring 4 can be rotated to perform focusing of the zoom ring 2 and the focus ring 4. When using the lens body 1, the hand is supported by the support handle 3, which can not only stabilize the position of the lens body 1, but also prevent the focus ring 4 and the zoom ring 2 from being touched, which makes the internal focus inaccurate.
