[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0026] Embodiment: a kind of ultra-small volume 200mhz low frequency duplexer, as shown in Figs. 1-4 shown, including support base 1 and low frequency duplexer 21, the inner wall of support base 1 relative two sides are all rotationally connected with rotating support column 2, the outer surface of rotating support column 2 is connected with two rotating support rods 3 symmetrically, rotating support rod 3 is rotationally connected with rotating connecting rod 5 at the end away from rotating support column 2, rotating connecting rod 5 is rotationally connected with sliding support block 6 at the end away from rotating support rod 3, sliding support block 6 is slidably connected with the inner wall of support base 1, and four sliding support blocks 6 are located at different positions on the same horizontal plane, connecting column 7 is installed on the upper end of sliding support block 6, connecting column 7 is slidably connected with the upper end of support base 1, connecting block 4 is installed on the upper end of connecting column 7, and the two connecting blocks 4 located at the same end are fixedly connected with clamping block 8 on the adjacent two sides.

[0027] When the low-frequency duplexer 21 is not clamped, the two clamping blocks 8 are in an expanded state, and the two rotating support rods 3 on the rotating support column 2 are in a horizontal state. When it is necessary to clamp the low-frequency duplexer 21, the rotating support column 2 is rotated, and the two rotating support rods 3 are rotated and gradually become vertical. Under the connection of the rotating connecting rod 5, the sliding support block 6 can be driven to move horizontally inward, and under the connection of the connecting column 7, the two clamping blocks 8 are driven to move inward to clamp the low-frequency duplexer 21. By driving the rotating support column 2 to rotate, the relative position of the rotating support rod 3 is changed, and under the connection of the rotating connecting rod 5, the position of the clamping block 8 is changed. The clamping block 8 can be flexibly adjusted according to the size of the ultra-small low-frequency duplexer 21, and can meet the ultra-small low-frequency duplexer 21 of various sizes, greatly improving the application range of the device and ensuring the universal effect of the device.

[0028] As shown in Figs. 1-4 , the motor 9 is installed at the middle position of the inner wall of the lower end of the support base 1, and the output end of the motor 9 is fixedly connected with the driving bevel gear 10.

[0029] The two rotating support columns 2 are simultaneously installed with rotating connecting columns 12 on the adjacent sides, the outer surface of the rotating connecting column 12 is fixedly connected with the driven bevel gear 13, and the driving bevel gear 10 is meshingly connected with the driven bevel gear 13.

[0030] When it is necessary to rotate the rotating support column 2, the motor 9 is operated to drive the driving bevel gear 10 to rotate, and under the meshing connection of the driving bevel gear 10 and the driven bevel gear 13, the driven bevel gear 13 and the rotating connecting column 12 are driven to rotate, thereby driving the rotating support column 2 to rotate. By driving the driving bevel gear 10 and the driven bevel gear 13 to meshingly rotate through the motor 9, the rotating support column 2 can be driven to operate, and the clamping block 8 can be flexibly adjusted. At the same time, under the connection of the rotating connecting column 12, the synchronism of the operation of the two rotating support columns 2 can be ensured, and the stability of the operation of the clamping block 8 can be ensured.

[0031] As shown in Figs. 1-4 , the support grooves 17 are formed in the inner walls of the relative two sides of the support base 1, the sliding blocks 15 are slidably arranged in the support grooves 17, and the sliding blocks 15 are fixedly connected with the sliding support blocks 6.

[0033] When the sliding support block 6 moves horizontally, the ball 16 and the guide limit of the sliding groove 18 ensure the stability of the direction of the sliding support block 6 during the horizontal movement, prevent the phenomenon of rotating the connecting rod 5 from occurring, and the ball 16 can reduce the friction between the sliding support block 6 and the support base 1, thereby ensuring the stability of the horizontal movement of the clamping block 8.

[0034] As shown in Figs. 1-4 The upper end of the support base 1 is symmetrically provided with two limiting grooves 14, and the two connecting columns 7 on the same side are simultaneously slid in the limiting grooves 14.

[0035] The upper end of the support base 1 is symmetrically provided with two guide rails 19, and the upper end of the connecting block 4 is provided with a sliding ring 20. The two sliding rings 20 on the same side are slid on the outer surfaces of the guide rails 19. When the clamping block 8 moves horizontally, the guide limit of the limiting groove 14 further ensures the accuracy of the direction of the clamping block 8 during the movement. At the same time, under the support limit of the guide rail 19 and the sliding ring 20, a slight gap is always maintained between the clamping block 8 and the upper surface of the support base 1, which reduces the friction between the clamping block 8 and the support base 1, prevents the clamping block 8 from being stuck during the movement, and effectively reduces the pressure of the clamping block 8 on the rotating support rod 3, thereby ensuring the stability of the rotating support rod 3.

[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
