[0021] refer to Figure 2 , Figure 3 and Figure 4 As shown, a positioning groove 11 is provided on the surface of the annular groove 3, a positioning block 12 is provided on one side of the column 1 of the retaining ring 4, an anti-skid pad 13 is provided on the top of the footrest 7, and the material of the anti-skid pad 13 is rubber, a first bolt 14 is provided on one side of the retaining ring 4, the surface of the first bolt 14 passes through the other side of the retaining ring 4 and is threadedly connected with a nut 15 through an anti-skid ring, plug blocks 16 are welded on the front and rear sides of the left side of the footrest 7, and installation grooves 17 for matching with the plug blocks 16 are provided on the front and rear sides of the right side of the top of the connecting block 5.

[0022] It should be noted that: by using the positioning groove 11 in conjunction with the positioning block 12, the snap ring 4 can be prevented from sliding when it is clamped in the annular groove 3, thereby increasing stability; the anti-slip pad 13 is made of rubber, which can increase the friction between the pedal 7 and the shoe, thereby achieving an anti-slip effect; the first bolt 14 and the nut 15 are used in conjunction to facilitate the connection and installation of the snap ring 4; the plug-in block 16 and the mounting groove 17 can improve the connection stability between the pedal 7 and the connecting block 5.

[0023] refer to Figure 3 and Figure 4As shown, the mounting mechanism 10 includes a screw 101, one side of which is fixedly connected to the inner wall of the fixed shell 9 through a bearing, the right side of the screw 101 penetrates into the inner cavity of the connecting groove 8 and is fixedly connected to a torsion ring 102, a threaded sleeve 103 is sleeved on the surface of the screw 101, the front and rear sides of the threaded sleeve 103 are fixedly connected to a connecting plate 104 through a rotating shaft, the two connecting plates 104 are fixedly connected to a guide plate 105 on one side away from the threaded sleeve 103 through a rotating shaft, the top and bottom of the guide plate 105 on the side away from the screw 101 are fixedly connected to an insertion rod 106, the inner cavity of the guide plate 105 is provided with a sliding rod 107, and one side of the sliding rod 107 is fixedly connected to the inner wall of the fixed shell 9 through a connecting piece.

[0024] It should be noted that twisting the torsion ring 102 causes the screw 101 to rotate. When the screw 101 rotates, the threaded sleeve 103 drives the connecting plate 104 and the guide plate 105 to move. At this time, the guide plate 105 assists in sliding on the surface of the slide rod 107. As the guide plate 105 moves, the insertion rod 106 is inserted into the inner cavity of the retaining groove 6 to install and fix the pedal 7.

[0025] Working principle: First, clamp the snap ring 4 in the inner cavity of the annular groove 3 through the first bolt 14 and the nut 15. At this time, the snap ring 4 drives the positioning block 12 to insert into the inner cavity of the positioning groove 11 to prevent the snap ring 4 from sliding. Then insert the fixing shell 9 into the inner cavity of the retaining groove 6. At this time, the foot pedal 7 drives the insert block 16 to insert into the inner cavity of the installation groove 17, thereby improving the connection stability. Then twist the torsion ring 102 to rotate the screw rod 101. When the screw rod 101 rotates, the threaded sleeve 103 drives the connecting plate 104 and the guide plate 105 to move. At this time, the guide plate 105 assists in sliding on the surface of the sliding rod 107. As the guide plate 105 moves, it drives the insert rod 106 to insert into the inner cavity of the retaining groove 6 to install and fix the foot pedal 7, thereby achieving the effect of convenient installation.
