The four corners of the handheld radio and television road tester body 10 are respectively detachably connected to the two L-shaped card slots 5 and the two inverted L-shaped card slots 9. Through the cooperation of the two L-shaped protective frames 4 and the L-shaped card slots 5 on the inner side thereof and the two inverted L-shaped protective frames 8 and the inverted L-shaped card slots 9 on the inner side thereof, the four corners of the handheld radio and television road tester can be effectively clamped, fixed and protected.
[0018] Further, such as Figure 2As shown, the two-way reciprocating assembly 3 includes an adjusting knob 31, a slider 32, a two-way lead screw 33 and a guide rod 34. The two-way lead screw 33 is rotatably connected between the left and right sides of the inner wall of the mounting groove 2, and the guide rod 34 is fixed between the left and right sides of the inner wall of the mounting groove 2. The two-way lead screw 33 and the guide rod 34 are parallel to each other. There are two sliders 32. The two opposite ends of the thread of the two-way lead screw 33 are respectively threadedly connected to the threaded holes on the sides of the two sliders 32, and the guide rod 34 is slidably connected to the sliding holes on the sides of the two sliders 32. The top ends of the two sliders 32 are respectively fixedly connected to the bottoms of the horizontal ends of the two L-shaped protective frames 4, and the end of the two-way lead screw 33 extending to the outside of the base 1 is correspondingly fixed with an adjusting knob 31. By turning the adjusting knob 31, the rotation of the two-way lead screw 33 is driven, and then the two sliders 32 are driven to move toward or away from each other. The horizontal adjustment can be performed according to the width of the handheld radio and television road tester body 10, and further tightening, clamping and fixing operations can be performed.
[0019] Further, such as Figure 4 As shown, the elastic lifting and adjusting component 7 includes a spring 71 and a lifting plate 72. The lower part of the outer side of the lifting plate 72 is correspondingly slidably connected in the adjusting groove 6. A spring 71 is fixedly installed between the bottom of the lifting plate 72 and the bottom of the inner wall of the adjusting groove 6. The top of the lifting plate 72 is fixedly connected to the bottom of the vertical end of the corresponding inverted L-shaped protective frame 8. The lifting plate 72 slides up and down in the adjusting groove 6, which facilitates the vertical adjustment of the inverted L-shaped protective frame 8 according to the height of the handheld radio and television road tester body 10. The spring 71 facilitates elastic tightening and fixing after adjustment.

[0022] Specifically, the L-shaped protective frame 4 and the inverted L-shaped protective frame 8 can be made of rubber, or rubber pads or silicone pads can be fixedly arranged on the inner walls of the L-shaped slot 5 and the inverted L-shaped slot 9 to provide further buffering and protection for the four corners and outer side of the handheld broadcast and television road tester body 10 to prevent damage caused by clamping and fixing.
[0023] When using:
[0024] When in use, first, by turning the adjusting knob 31, the two-way lead screw 33 is driven to rotate, and then the two sliders 32 are driven to move toward or away from each other, and horizontal adjustment can be performed according to the width of the handheld radio and television road tester body 10. Then, by pulling the two inverted L-shaped protective frames 8, the two lifting plates 72 are driven to rise and fall, and vertical adjustment can be performed according to the height of the handheld radio and television road tester body 10. The handheld radio and television road tester body 10 is placed between the two L-shaped protective frames 4 and the two inverted L-shaped protective frames 8, and the adjusting knob 31 is continued to be turned, and the two inverted L-shaped protective frames 8 are loosened so that the spring 71 is contracted and tightened, so that the two L-shaped protective frames 4 and the L-shaped slots 5 inside thereof and the two inverted L-shaped protective frames 8 and the inverted L-shaped slots 9 inside thereof can be firmly clamped and fixed to the four corners of the handheld radio and television road tester body 10, respectively, to complete the effective clamping, fixing and protection of the outer side of the handheld radio and television road tester body 10.
[0025] The two-way reciprocating assembly 3 can be used to adjust horizontally according to the width of different handheld radio and television road testers, and the elastic lifting adjustment assembly 7 can be used to adjust vertically according to the height of different handheld radio and television road testers. At the same time, through the cooperation of the two L-shaped protective frames 4 and the L-shaped card slots 5 inside thereof and the two inverted L-shaped protective frames 8 and the inverted L-shaped card slots 9 inside thereof, the four corners of the handheld radio and television road tester can be effectively clamped, fixed and protected.
