[0033] The adjusting turntable 14 is keyed connected to the outer surface of the rotating shaft 10, the sliding shaft 15 is integrally formed at one end of the rotating shaft 10, the fixed frame 17 is welded at one end of the bending block 2, the sliding shaft 15 slides in the fixed frame 17, the pin 16 is inserted into the outer surface of the sliding shaft 15, the pin 16 is located on one side of the fixed frame 17, the side hooks 19 are welded at the other end of the first sliding plate 5 and the second sliding plate 6, and the two top hooks 21 are fixed on one side of the bending block 2 by bolts.

[0034] With reference to Figure 3 And Figure 4 , the two sides of the first sliding plate 5 and the second sliding plate 6 are provided with sliding grooves 7, and the sliding grooves 7 are in sliding connection with the inner wall of the bending block 2. The inner side of the side hook 19 is fixed with a first anti-skid pad 20 through a bolt. The inner side of the top hook 21 is fixed with a second anti-skid pad 22 through a bolt. The first anti-skid groove 29 and the second anti-skid groove 30 can prevent the risk of slipping of the staff.

[0035] With reference to Figure 6 , the bottom of the main pedal 1 is welded with a triangular support 18.
