Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A signal receiving controller sensitivity testing device, such as Figure 1 and Figure 2 As shown, it includes a base 1, a motor 2, a screw 3, a transmitter 4, a signal receiving controller 5, an indicator light 6 and an adjustment mechanism 7. The base 1 is I-shaped, the motor 2 is connected to the upper right part of the base 1, the screw 3 is connected to the output shaft of the motor 2, the screw 3 is rotatably connected to the base 1, and the signal receiving controller 5 is threadedly connected to the screw 3.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism 7 includes a sliding frame 71, a hydraulic cylinder 72, a lifting rack 73, a rotating shaft 74 and a template 75. Three sliding frames 71 are slidably connected to the base 1. The front and rear sides of the sliding frames 71 are connected to hydraulic cylinders 72. A connecting plate is provided between the telescopic ends of the front and rear two adjacent hydraulic cylinders 72. The lower sides of the front and rear parts of the connecting plate are connected to the lifting rack 73. The upper part of the sliding frame 71 is rotatably connected to two left and right rotating shafts 74. The front and rear parts of the rotating shaft 74 are provided with gears, which are meshed with the adjacent lifting racks 73. The rotating shaft 74 is clamped with a template 75.

[0023] like Figure 1 and Figure 5 As shown, a detection mechanism 8 is also included, which includes a torsion spring 81, an isolation plate 82 and a detection head 83.

After the test is completed, the hydraulic cylinder 72 is closed.
