[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0019] Figure 2 It is a schematic cross-sectional structure diagram of an integrated multi-size focusing fixture in one embodiment of the utility model;

[0020] Figure 3 The figure is a schematic top view of the structure of an integrated multi-size focusing fixture in one embodiment of the utility model. DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] See also Figure 2 and Figure 3 As shown, an integrated multi-size focusing fixture 10 includes: a focusing positioning seat 100 and a focusing positioning structure 200, wherein the focusing positioning structure 200 is disposed on the focusing positioning seat 100, and the focusing positioning structure 200 includes a plurality of focusing positioning holes which are sequentially interconnected, and the size of each focusing positioning hole gradually decreases from one side of the focusing positioning seat 200 to the opposite side, so that the focusing positioning structure 200 has a stepped structure.

[0023] It should be noted that if Figure 1 As shown, it is an existing focus ring structure, which has only one size of focus hole, so it can only be used for the focus operation of one camera module. By setting a focus positioning structure with multiple focus positioning holes on the same focus positioning seat 100, that is, integrating focus positioning holes of different sizes on the same focus fixture, different focus positioning holes correspond to camera modules of different sizes, so that the same focus fixture can be applied to camera modules of different sizes, thereby improving the versatility of the focus fixture. Theoretically, the more the number of focus positioning holes, the better, so that more camera modules can be adapted, so that material costs can be saved and management can be facilitated, while reducing the problem of loss caused by too many focusing fixtures and poor storage. Among them, the size of each focusing positioning hole is gradually reduced from one side of the focusing positioning seat 200 to the opposite side, that is, the size of the adjustment positioning hole closer to the outside is larger than the size of the adjustment positioning hole closer to the inside. In this way, there is enough space when the focusing fixture buckles the camera module downward to avoid interference between the camera module and the focusing positioning structure.

[0024] Specifically, in the present embodiment, the focus positioning structure 200 includes a first focus positioning hole 210, a second focus positioning hole 220, a third focus positioning hole 230 and a fourth focus positioning hole 240 which are sequentially connected to each other, and the diameter of the first focus positioning hole 210 is greater than the diameter of the second focus positioning hole 220, the diameter of the third focus positioning hole 230, and the diameter of the fourth focus positioning hole 240. In this way, when the focusing fixture is buckled into the camera module, there is enough space to avoid interference between the camera module and the focus positioning structure. In the present embodiment, the width of the step surface formed by the first focus positioning hole 210, the second focus positioning hole 220, and the third focus positioning hole 230 which are sequentially connected to each other is greater than or equal to 2 mm; further, the depth of the first focus positioning hole 210, the depth of the second focus positioning hole 220, the depth of the third focus positioning hole 230 and the depth of the fourth focus positioning hole 240 are greater than or equal to 2 mm. That is, the distance between the two stepped planes formed by each focusing positioning hole is greater than or equal to 2 mm; in this way, sufficient strength can be ensured, so when the focusing positioning hole is buckled and locked to the camera module for focusing, the problem of thread slippage can be avoided.

[0025] Furthermore, the outer surface of the focus positioning seat 100 is provided with an anti-skid structure (not shown). In this way, the operator's hand can grasp the anti-skid structure and perform focusing operation on the camera module, thereby avoiding the phenomenon of hand slipping during the focusing process. For example, the anti-skid structure includes a plurality of anti-skid protrusions distributed in an array, thereby increasing the friction between the hand and the focus positioning seat 100. In another embodiment, a layer of rubber ring can also be provided on the outer surface of the focus positioning seat 100, and an anti-skid protrusion can be provided on the rubber ring to play an anti-skid role.

[0026] Preferably, the focusing and positioning seat 100 is in a circular structure, which makes it easier for an operator to hold the focusing and positioning seat 100 during a rotation and focusing operation.

[0027] Preferably, each focusing positioning hole is a circular structure, and the structure of the focusing positioning hole matches the structure of the camera module.

[0028] Preferably, the focus positioning seat 100 is made of metal. The use of a focus positioning seat 100 made of metal can ensure that the focus fixture has sufficient strength. For example, preferably, the focus positioning seat is made of copper. Or preferably, the focus positioning seat 100 is made of aluminum. Since aluminum and copper are both metal materials that will not rust, it can ensure that the focus fixture can be used for a long time.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
