DETAILED DESCRIPTION

[0044] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes on different embodiments, which do not deviate from the scope of the present application, and the description and drawings in essence are used for illustration, not for limiting the present application.

[0045] In the description of the present application, the orientation or position relationship indicated by the terms "upper", "lower" and the like is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the structure referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0046] Please refer to Figure 1 and Figure 2 The present application provides a technical scheme: a gear type adjusting device, comprising a holder base 1 and a rotation shaft 2 rotatably installed on the holder base 1, a platform for installing a photography auxiliary device is arranged on the rotation shaft 2, the holder base 1 comprises a mounting seat 25 and two mounting arms 26, the two mounting arms 26 are integrally formed with the mounting seat 25 and oppositely arranged on the top of the mounting seat 25, the holder base 1 as a whole is concave, and a dovetail groove is arranged at the bottom for mounting the holder base 1 on a camera rabbit cage;

[0047] Please refer to Figure 4One of the mounting arms 26 is provided with a first through hole 27, and the inner wall of the first through hole 27 is provided with a positioning protrusion 28 extending along the center line of the first through hole 27. A second locking piece 4 is mounted in the first through hole 27, and the outer circumferential surface of the second locking piece 4 is provided with a positioning groove 29 which is in sliding fit with the positioning protrusion 28, thereby limiting the rotation of the second locking piece 4 along the circumferential direction of the first through hole 27.

[0048] Please refer to Figures 1 to 3 In addition, the other mounting arm 26 is provided with a second through hole 30 in a stepped shape, and the end of the rotating shaft 2 close to the second through hole 30 is provided with a positioning groove 31. A positioning buckle 32 is inserted into the second through hole 30 and the positioning groove 31. A gasket 33 is arranged between the stepped inner wall of the second through hole 30 and the positioning buckle 32, and between the mounting arm 26 and the rotating shaft 2. The gasket 33 is a 1mm thick nylon gasket. A connecting screw 34 is mounted in the positioning buckle 32 for connecting the rotating shaft 2 and the mounting arm 26. The connecting screw 34 is screwed with the rotating shaft 2 through the positioning buckle 32, so as to drive the positioning buckle 32 to clamp the mounting arm 26 together with the rotating shaft 2. The damping force between the mounting arm 26 and the rotating shaft 2 can be adjusted by adjusting the tightness of the connecting screw 34. When the positioning buckle 32 is inserted into the positioning groove 31, the positioning buckle 32 cannot rotate relative to the rotating shaft 2. Therefore, when the rotating shaft 2 is rotated, the rotating shaft 2 can drive the positioning buckle 32 and the connecting screw 34 to rotate, so as to ensure constant damping force, and the rotation of the rotating shaft 2 is limited by the positioning buckle 32, which is beneficial to the rotation of the connecting screw 34.

[0049] Please refer to Figure 1 、 Figure 4 and Figure 7 The rotating shaft 2 is provided with a first locking piece 3.
