[0041] Through the above scheme, in the working state, the first shading plate 321 and the second shading plate 322 form a preset angle with each other, and the first shading edge 323 is supported by the fixing portion 310 or the frame 200 to limit the relative rotation of the first shading plate 321 and the second shading plate 322; the triangular second shading portion 330 can be detachably connected to the two opposite edges of the first shading plate 321 through the first sealing edge 331 and can be detachably connected to the two opposite edges of the second shading plate 322 through the second sealing edge 332, thereby blocking the gap between the first shading plate 321, the second shading plate 322 and the frame 200, and finally making the shading cover 300 blocks one side of the spectroscope 100, which can ensure that the spectroscope 100 only receives the light source on one side to ensure the spectroscopic effect; the staff can release the detachable connection relationship between the first shading plate 321 and the second shading portion 330, the detachable connection relationship between the second shading plate 322 and the second shading portion 330, and the supporting relationship between the first shading edge 323 and the frame 200, and make the first shading plate 321, the second shading plate 322 and the two second shading portions 330 rotate relative to the frame 200 and stacked on one side of the spectroscope 100, so that the teleprompter bracket enters the storage state, thereby reducing the space occupied by the teleprompter bracket.

[0042] Specifically, according to some embodiments of the present invention, taking the teleprompter bracket in working state as an example, the first shading plate 321 and the second shading plate 322 are both rectangular plates, the two opposite plate edges of the first shading plate 321 are respectively rotatably connected to the fixing portion 310 and the second shading plate 322, one of the two opposite plate edges of the second shading plate 322 is connected to the plate edge of the first shading plate 321, and the other of the two opposite plate edges of the second shading plate 322 is connected to the first shading edge 323; the first sealing edge 331 is supported by the frame 200, so that The first shading plate 321 and the second shading plate 322 are bent relative to each other at a preset angle; the other two opposite plate edges of the first shading plate 321 are respectively connected to the first sealing edges 331 of different second shading parts 330 by zippers; the other two opposite plate edges of the second shading plate 322 are respectively connected to the second sealing edges 332 of different second shading parts 330 by zippers; and one of the other two opposite plate edges is rotatably connected to the plate edge of the first shading plate 321, and the other of the other two opposite plate edges is connected to the first shading edge 323; please refer to Figure 1 As shown, the above connection relationship enables the light shield 300 and the lens frame 200 to enclose a shape similar to a triangular prism, completely shielding one side of the beam splitter 100.

[0043] It should be noted that, without departing from the inventive concept of the present utility model, the first light shielding plate 321 and the second light shielding plate 322 in the above embodiment are rectangular plates and can be replaced by plate structures of other shapes. For example, the first light shielding plate 321 and the second light shielding plate 322 are also set to be trapezoidal.

[0044] In the above embodiment, in order to bend the first shading plate 321 and the second shading plate 322 relative to each other at a preset angle in the working state, the first shading edge 323 is supported by the frame 200; the following describes a solution to make the frame 200 support the first shading edge 323 more stably.

[0045] For further information, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the first light shielding edge 323 and / or the lens frame 200 include a magnetic attraction portion 400; in the working state, the first light shielding edge 323 and the lens frame 200 are magnetically attracted to each other through the magnetic attraction portion 400. Through the above solution, when the first light shielding edge 323 is supported on the lens frame 200, the first light shielding edge 323 and / or the lens frame 200 are attracted to each other through the magnetic attraction portion 400, which can further enhance the stability of the supporting relationship between the lens frame 200 and the first light shielding edge 323.

[0046] Specifically, according to some embodiments of the present invention, a plurality of magnetic attraction portions 400 are embedded on the frame 200 . The magnetic attraction portions 400 are magnetic. In the working state, the first light shielding edge 323 can be attracted by the magnet and fixed to the surface of the frame 200 .

[0047] For further information, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the beam splitter 100 has a light emitting surface 110, and the light emitting surface 110 faces the first direction. The frame 200 includes a frame body 210 and a protrusion 220. The frame body 210 is connected to and covers the edge of the beam splitter 100. The protrusion 220 is connected to the frame body 210 and protrudes in the opposite direction of the frame body 210 toward the first direction. In the working state, the protrusion 220 abuts against the side of the first light shielding edge 323 away from the first light shielding plate 321. Through the above scheme, in the working state, the protrusion 220 abuts against the first light shielding edge 323 to limit the first light shielding edge 323 from being away from the first light shielding plate 321, thereby preventing the first light shielding edge 323 from being separated from the original position when shaking and causing light leakage.

[0048] The above mentioned scheme of setting a magnetic attraction portion 400 on the first light-shielding edge 323 and / or the frame 200. On the basis of the above scheme, a protrusion 220 is additionally set on the frame 210, and the magnetic attraction portion 400 is embedded in the frame 210. The protrusion 220 can provide a guide for the magnetic attraction between the first light-shielding edge 323 and the frame 210. When the staff manually installs the first light-shielding edge 323, the side of the first light-shielding edge 323 away from the first light baffle can first abut against the protrusion 220, and then rely on the magnetic attraction of the attraction portion to set the first light-shielding edge 323 at a preset position on the frame 210; the protrusion 220 in the working state can also limit the first light-shielding edge 323 from being away from the first light-shielding plate 321, so as to prevent light leakage from the light shielding cover 300.

[0049] For further information, please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the beam splitter 100 has a light emitting surface 110, and the light emitting surface 110 faces the first direction (ie Figure 3 , Figure 5 , Figure 6 The mirror frame 200 includes a first frame bar 230 and a second frame bar 240. The first frame bar 230 is detachably connected to the second frame bar 240 in the second direction (i.e. Figure 3 , Figure 5 , Figure 6 The first frame bar 230 and the second frame bar 240 are connected to the first frame bar 230 and the second frame bar 240 to define a storage cavity. The second direction is perpendicular to the first direction. The spectroscope 100 is stored in the storage cavity. The first frame bar 230 and the second frame bar 240 cover the peripheral side of the spectroscope 100 together. According to the above scheme, when installing the spectroscope 100, the staff can remove the first frame bar 230 from the second frame bar 240, put the spectroscope 100 into the space inside the second frame bar 240 in the opposite direction of the second direction, and then install the first frame bar 230 on the second frame bar 240, so that the peripheral side of the spectroscope 100 is covered by the first frame bar 230 and the second frame bar 240. On the other hand, since the first frame bar 230 is detachably connected to one side of the second frame bar 240 in the second direction, the second frame bar 240 can be set in an integrally formed form, and the spectroscope 100 stored in the storage cavity will not move along the first direction due to the restriction of the second frame bar 240.

[0050] It should be noted that the accommodation cavity proposed in the present invention should be understood by those skilled in the art as a space in the frame 200 for accommodating the spectroscope 100, and when the spectroscope 100 is accommodated in the accommodation cavity, it can be confined in the frame 200 and cannot be separated from the frame 200. Therefore, without departing from the above-mentioned inventive concept, those skilled in the art can set a groove in the first frame bar 230 or the second frame bar 240, so that the space in the groove becomes a part of the accommodation cavity, and the spectroscope 100 is restricted from being separated from the groove by the first frame bar 230 and the second frame bar 240. Exemplarily, a preferred solution is introduced below.

[0051] For further information, please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the first frame bar 230 has a first slot, the second frame bar 240 has a second slot 240a, the first slot extends along the second direction, the second slot 240a extends in the opposite direction of the second direction, and the first slot and the second slot 240a form a part of the accommodating cavity. Through the above scheme, when the beam splitter 100 is accommodated in the accommodating cavity, it extends into the first slot and the second slot 240a at the same time, and the first frame bar 230 and the second frame bar 240 can simultaneously limit the movement of the beam splitter 100 to prevent the beam splitter 100 from detaching from the frame 200.

[0052] For more information, see Figure 5 , Figure 6 , Figure 7 As shown, according to some embodiments of the present invention, the second frame strip 240 includes a middle frame 242 and two side frames 241, one end of the two side frames 241 is respectively connected to the opposite ends of the middle frame 242, and the other ends of the two side frames 241 are respectively detachably connected to the opposite ends of the first frame strip 230; the second slot 240a starts from one end of the two side frames 241 away from the middle frame 242 and is in the opposite direction of the second direction (that is, Figure 5 When the beam splitter 100 is accommodated in the accommodating cavity, the inner wall of the second slot 240a can limit the movement of the beam splitter 100 in the up, down, left, right and rear directions, and the inner wall of the first slot can limit the movement of the beam splitter 100 in the up, down and front directions. The first frame bar 230 and the second frame bar 240 simultaneously limit the movement of the beam splitter 100 to prevent the beam splitter 100 from detaching from the frame 200.

[0053] For further information, please refer to Figure 7As shown, the teleprompter bracket also includes a plurality of buffers 500, and the plurality of buffers 500 are elastic. The plurality of buffers 500 are clamped between the peripheral side of the beam splitter 100 and the inside of the first slot, or the plurality of buffers 500 are clamped between the peripheral side of the beam splitter 100 and the inside of the second slot 240a. Through the above scheme, the beam splitter 100 accommodated in the accommodating cavity can be connected to the first frame bar 230 or the second frame bar 240 through the buffer 500, and the buffer 500 can fill the gap between the beam splitter 100 and the first frame bar 230, or can fill the gap between the beam splitter 100 and the second frame bar 240, so as to prevent the beam splitter 100 from shaking in the accommodating cavity. On the other hand, the elastic buffer 500 can prevent the teleprompter bracket from damaging the beam splitter 100 when it is impacted.

[0054] The above-mentioned solution of setting the first slot in the first frame bar 230 and setting the second slot 240a in the second frame bar 240 has been described. Based on the above solution, further, please refer to Figure 5 As shown, the second frame bar 240 includes two side frames 241 and a middle frame 242, one end of the two side frames 241 is respectively connected to the opposite ends of the middle frame 242, and the other ends of the two side frames 241 are respectively detachably connected to the opposite ends of the first frame bar 230; the length direction of each side frame 241 is perpendicular to the length direction of the first frame bar 230 and perpendicular to the length direction of the middle frame 242. Through the above scheme, the accommodating cavity formed by the second frame bar 240 and the first frame bar 230 can accommodate the rectangular beam splitter 100, so that the reflection area of ​​the beam splitter 100 is larger and more lines can be displayed. On the other hand, the light-transmitting area of ​​the rectangular beam splitter 100 is also more suitable for the filming of the camera.

[0055] For further information, please refer to Figure 5 As shown, the second frame strip 240 also includes two bending portions 243, the two ends of the middle frame 242 in the length direction are respectively connected to a bending portion 243, and one end of each side frame 241 in the length direction is connected to a bending portion 243; the directly connected middle frame 242, side frame 241 and bending portion 243 all define a bending groove 244, and the bending groove 244 runs through the second frame strip 240 along the first direction. Through the above scheme, since the middle frame 242 and the side frame 241 have an angle, the bending groove 244 defined by the connected middle frame 242, side frame 241 and bending portion 243 can reduce the rigidity of the bending portion 243. In the process of producing the second frame strip 240, the second frame strip 240 in a straight line can be bent around the bending portion 243 to make the second frame strip 240 easier to form.

[0056] It should be noted that, without departing from the inventive concept of the utility model, when a sunshade 300 is provided on the lens frame 200 in the above embodiment, the fixing portion 310 can be connected to the first frame bar 230 alone, or to the second frame bar 240 alone, or to both the first frame bar 230 and the second frame bar 240 at the same time; in the working state, the first sunshade edge 323 can be supported by the first frame bar 230 or by the second frame bar 240.

[0057] For further information, please refer to Figure 1 , Figure 2 , Figure 3 As shown, the fixing portion 310 is connected to the second frame bar 240; the first light shielding edge 323 is supported by the first frame bar 230. Through the above solution, when the staff needs to replace the beam splitter 100 in the frame 200, they only need to release the supporting relationship of the first light shielding edge 323 to separate the first frame bar 230 and the second frame bar 240 and take the beam splitter 100 out of the accommodating cavity.

[0058] The foregoing has described a scheme in which the frame 200 limits the first light-shielding edge 323 by means of a protrusion 220 , and a scheme in which a magnetic attraction portion 400 is provided on the first light-shielding edge 323 and / or the frame 200 . Based on the above two schemes, those skilled in the art may selectively provide a protrusion 220 and / or embed a magnetic attraction portion 400 on the first frame strip 230 .

[0059] Furthermore, the fixing portion 310 is connected to the second frame strip 240 by a Velcro method.
