[0038] A plurality of friction protrusions 31 are provided on the end surface of the friction rubber block 3 .

[0039] The working principle of the present invention is as follows: Figure 1-6As shown, the pedal block 1 is connected to the pedal shaft to achieve a rotational connection between the pedal block 1 and the pedal shaft. A sliding groove 10 is provided on the side wall of the pedal block 1, a rotating shaft 11 is provided at the end of the pedal block 1, and a rotating block 4 is provided at the end of the pedal block 1. The rotating block 4 is provided with a rotating groove 44, and the rotating shaft 11 is rotatably connected to the rotating groove 44. A sliding groove 2 40 is provided on the side wall of the rotating block 4, wherein the sliding groove 10 and the sliding groove 2 40 are connected. An extension block 2 is provided in the sliding groove 10, and the extension block 2 is slidably connected to the sliding groove 2 40. A guide block 41 is provided on the bottom surface of the sliding groove 2 40, and the extension block 2 is provided with a clearance groove 20, and the guide block 41 is slidably connected to the clearance groove 20. A plurality of limit blocks 21 are provided in the clearance groove 20, and the limit block 21 is provided with a limit groove 22. A plurality of limit grooves 22 are arranged at equal intervals on the inner wall of the clearance groove 20. The guide block 41 consists of a guide post 42 and a locking block 43, with the sidewalls of the locking block 43 connected to the sidewalls of the guide post 42. When the extension block 2 extends outward, the guide post 42 can be inserted into different guide slots, achieving different extension lengths of the extension block 2. This ensures that different extension lengths can accommodate different cyclists' foot widths and ensure a good riding experience. When the extension block 2 extends to its maximum distance, the locking block 43 inserts into the locking slot 28, causing the limiting protrusion 430 provided on the locking block 43 to engage with the locking slot 28, connecting the extension block 2 to the rotating block 4 and achieving the maximum extension distance of the extension block 2, meeting the cyclist's foot width requirements and ensuring a good riding experience.

[0040] A fixing groove 24 is provided at the outer end of the extension block 2, a connecting block 23 is provided in the fixing groove 24, and a spring 25 is provided between the connecting block 23 and the fixing groove 24. The connecting block 23 is rotatably connected to the stopper 5 via a connecting shaft, so that the stopper 5 can swing. Magnet blocks 50 are provided on both sides of the stopper 5, and a patch 26 is provided at the end of the extension block 2, wherein the patch 26 is made of a special material. When the extension block 2 is extended, the stopper 5 is adjusted to swing so that the magnet block 50 and the patch 26 are magnetically attached to each other, ensuring that when the extension block 2 is extended, the stopper 5 is in a vertical state, ensuring that the rider's feet are restricted by the stopper 5, preventing the rider's feet from sliding outward during riding, ensuring the rider's riding effect, and improving the riding experience. Since a spring 25 is provided between the connecting block 23 and the extension block 2, the spring 25 can ensure that the stopper 5 and the rider's feet always remain in close contact, ensuring the rider's riding experience and riding effect.

[0041] A mounting groove 27 is provided below the extension block 2. A friction rubber block 3 is bonded into the mounting groove 27. The end surface of the friction rubber block 3 is provided with a plurality of friction protrusions 31. Each of the friction protrusions 31 has an arc-shaped cross-section and is made of rubber. The provision of friction protrusions 31 enhances the friction between the rider's shoe and the friction rubber block 3, ensuring a comfortable and effective riding experience.

[0042] Two positioning protrusions 12 are provided on the end surface of the pedal block 1, one on either side of the rotation axis 11 and flush with the axis. Two positioning grooves 45 are provided on the rotating block 4, one on either side of the rotation groove 44 and flush with the rotation groove 44. After the rotating block 4 has rotated 180 degrees, the positioning protrusions 12 can still fit into the corresponding positioning grooves 45, ensuring that the rotating block 4 and the pedal block 1 are properly positioned.

[0043] The present invention operates as follows: the extension block 2's outward length is adjusted based on the rider's foot width. When adjusting the extension block 2's outward length, the guide post 42 engages with the limiting slot 22 at different locations to ensure the desired outward length of the extension block 2. When the extension block 2's outward length is desired to be maximized, the extension block 2 is moved outward until the locking block 43 engages with the limiting slot 22. Simultaneously, the limiting protrusion 430 on the locking block 43 engages with the locking slot 28. Since the extension block 2's outward length is maximized at this point, the rotating block 4 is rotated to rotate the friction rubber block 3 below the extension block 2 upward. The friction protrusion 31 on the friction rubber block 3 increases friction, thereby improving the overall friction of the pedal and ensuring the rider's riding experience and performance. At the same time, after the extension block 2 is extended, the stop block 5 is rotated to flip it, so that the magnet block 50 is magnetically connected to the patch 26 set on the extension block 2, ensuring that the stop block 5 is in a vertical state, so that the stop block 5 can limit the rider's feet, preventing the rider's feet from sliding outward while riding, and ensuring the rider's riding experience and riding effect.

[0044] When the extension block 2 does not need to be extended outward, the stop block 5 is placed in the connecting groove 46 provided at the outer end of the rotating block 4 .

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
