[0028] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The present invention is further described in detail below in conjunction with the embodiments:

[0030] like Figure 1-5 As shown, the utility model provides a waist-level viewfinder that can be opened and closed with one button, including a base 1, a lower cover 2, an upper cover 3, a magnifying glass bracket 4 and a bottom frame 5. The upper surface of the base 1 is fixedly connected with a base receiving frame 8 for clamping the inner wall of the upper cover 3. One end of the upper cover 3 is rotatably connected to the inner wall of one end of the base receiving frame 8, and one end of the lower cover 2 is rotatably connected to one end of the base 1. The upper cover 3 and the lower cover 2 open and close oppositely.

[0031] The inner wall of the base 1 is fixedly connected with a base magnetic block 7, the top of the inner wall of the upper cover 3 is fixedly connected with an upper cover protrusion 10, and the bottom surface of one end of the magnifying glass bracket 4 is provided with a bracket card slot 16 docking with the upper cover protrusion 10, and the inner wall of one end of the upper cover 3 is respectively fixedly connected with a bracket adapter mounting block 12 and a positioning block 13, and the side where the bracket adapter mounting block 12 and the positioning block 13 are close to each other is rotatably connected to one end of the magnifying glass bracket 4, the upper surface of the lower cover 2 is fixedly connected with a lower cover magnetic block 18, and the bottom surface of the magnifying glass bracket 4 is fixedly connected with a bracket magnetic block 21 adsorbed with the lower cover magnetic block 18.

[0032] An axial hole 9 is provided on the side surface of one end of the base receiving frame 8, and an axial rod mounting tube 14 docking with the axial hole 9 is fixedly connected to the bottom surface of one end of the upper cover 3, and the inner wall of the axial rod mounting tube 14 is rotatably connected to the inner wall of the axial hole 9 with an axial rod, and the bottom surface of the outer wall of the base 1 is fixedly connected to an L-shaped hook 6 for clamping with the bottom frame 5.

[0033] A lower cover transverse plate 19 is fixedly connected to one end side of the lower cover 2, and a rotating rod is rotatably connected to the inner wall of the lower cover transverse plate 19. The lower cover 2 is rotatably connected to the inner wall of the base 1 through the rotating rod, and a torsion spring is sleeved on the outer wall of the rotating rod.

[0034] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, both sides of the lower cover 2 are fixedly connected with a lower cover outer arc frame edge 20, and the bottom surface of the upper cover 3 is fixedly connected with an upper cover outer arc frame edge 11.

[0035] The outer wall of the lower cover outer arc frame edge 20 overlaps with the inner wall of the upper cover outer arc frame edge 11 .

[0036] The inner wall of the bracket slot 16 is snapped with the outer wall of the upper cover protrusion 10, and a mounting block adapter slot 15 adapted to the bracket adapter mounting block 12 is opened at one end of the magnifying glass bracket 4, and a bracket shaft hole 17 is opened at one end of the magnifying glass bracket 4, and a torsion spring is arranged between the mounting block adapter slot 15 and the bracket adapter mounting block 12.

[0037] Each structural component is formed in one step by 3D printing using high-quality resin, with high strength, high hardness and high precision.

[0038] Let's talk about the working principle of the waist-level viewfinder that can be opened and closed with one button.

[0039] like Figure 1-5As shown, when in use, the front end of the base 1 is first inserted into the camera slot, and then the whole is rotated and inserted, and then one end of the upper cover 3 is pressed to disengage the inner wall of the upper cover 3 and the base receiving frame 8 from the locking state. At this time, the torsion spring on the lower cover 2 drives the lower cover 2 to start rotating until it forms a vertical state with the base 1, and the upper cover 3 also rotates under the state of the torsion spring to form a vertical state with the base 1, realizing automatic magnetic pop-up with one finger. When closing, after the upper cover 3 is pressed and closed, the outer arc frame edge 11 of the upper cover squeezes the lower cover horizontal plate 19 to drive the lower cover 2 to reset. When the inner wall of the upper cover 3 and the outer wall of the base receiving frame 8 are sleeved and closed, the bracket magnetic block 21 and the lower cover magnetic block 18 are adsorbed on each other.

[0040] When the magnifying glass bracket 4 is used, one end of the magnifying glass bracket 4 is moved to make the bracket slot 16 disengage from the upper cover protrusion 10 and open under the action of the torsion spring, otherwise the magnifying glass bracket 4 is folded.

[0041] It should be noted that, in this article, the terms "include", "comprises" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "includes one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to a general technician in the technical field. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
