The signal input terminal 18 can transmit the signal from the signal output terminal 1 2 and the signal output terminal 2 3 through the filter 4. A filter frame 6 is fixed in the pipe body 1. One end of the filter frame 6 is connected to an upper pressure plate 7, and the other end is connected to a clamping mechanism for clamping the filter 4. The clamping mechanism includes a lower pressure plate 8, a guide seat 9, and a locking head 14. The lower pressure plate 8 is slidably connected to the guide seat 9. The locking head 14 is used to position the lower pressure plate 8. The guide seat 9 is connected to a driving mechanism for driving the guide seat 9 to move toward the upper pressure plate 7.

[0021] The locking head 14 can be pushed to achieve the lifting and lowering of the lower pressing plate 8, and the position of the limiting groove 10 on the side of the lower pressing plate 8 can be changed, thereby changing the inclination angle of the filter 4, that is, the signal transmission direction can be controlled, which is convenient for people to use.

[0022] The clamping mechanism also includes a sliding hole 11 and a sliding column 12. The sliding hole 11 is arranged on the side of the guide seat 9, and the sliding hole 11 is used to guide the sliding column 12. One end of the sliding column 12 is connected to the lower pressing plate 8, and the other end is threadedly connected to the locking head 14. When the lower pressing plate 8 is moved, the locking head 14 is loosened by a tool. At this time, the lower pressing plate 8 is in a loosened state, and then the locking head 14 is driven to realize the movement of the lower pressing plate 8. When the lower pressing plate 8 is in a suitable position, the locking head 14 is tightened by a tool so that the locking head 14 is pressed against the guide seat 9, thereby realizing the locking and fixing of the lower pressing plate 8, improving the stability of the lower pressing plate 8, and the operation is simple and convenient. When the lower pressing plate 8 moves, the position of the limiting groove 10 located below changes relative to the position of the limiting groove 10 above, thereby facilitating the adjustment of the inclination angle of the filter 4.

[0023] The slide post 12 is slidably connected to the slide hole 11, and the slide hole 11 is a rectangular hole. When the lower pressing plate 8 moves, the slide post 12 slides in the slide hole 11, and combined with the use of the guide seat 9, the stability of the lower pressing plate 8 in lifting and lowering can be improved.
