[0028] As shown in the figure, Figures 4 to 8 The limiting mechanism 6 includes a mounting block 601 mounted on one side of the top inner wall of the protective cover 5. A bidirectional screw rod 602 is rotatably mounted in the mounting block 601. One end of the bidirectional screw rod 602 is rotatably arranged on the inner wall of one end of the protective cover 5, and the other end of the bidirectional screw rod 602 is arranged outside the protective cover 5 and provided with an adjusting knob 603 at the end.
