In addition, in the present embodiment, the length of the bottom surface 141 of the step portion 14 in the longitudinal direction: length of the bottom face 141 in the transverse direction: the length of the first chamfer surface 14211 in the transverse direction is 1:7-8: 10-12; and the length of the first chamfered surface 14211 in the vertical direction is equal to the length of the bottom surface 141 in the longitudinal direction, so as to provide a better curved guiding shape, effectively position the cramp 20, and facilitate the lateral disengagement of the cramp 20.
When the cramp 20 and the pedal body 10 are installed, firstly, the cramp 20 is inclined forwards, and the front clamping part 21 is plugged below the stopping part of the pedal body 10; then the positioning structure 15 is moved to the releasing position, and the cramp 20 is flatly attached to the top surface of the pedal body 10; then, the positioning structure 15 is moved to a positioning position to complete the installation and positioning of the cramp 20; at this time, the abutting block 23 abuts against the side wall 142 of the step portion 14.
During the process that the user steps on the cramp 20 with the sole 40, the cramp 20 is forced backward and upward; at this time, since the abutting block 23 of the buckle piece 20 abuts against the side wall 142 of the step portion 14, the buckle piece 20 cannot move backwards and upwards, thereby ensuring stable use of the buckle piece 20. Meanwhile, the first guide surface 1422 and the second guide surface 1423 of the step portion 14 are in a concave arc shape, so that the cramp 20 can rotate slightly, the front clamping portion 21 can be conveniently separated from the stopping portion, and the detachment is more convenient.
Meanwhile, since the wear-resistant plate 30 has the wing 31 inclined upward, when the buckle piece 20 is rotated and removed by using the first guide surface 1422 or the second guide surface 1423, the buckle piece 20 can slide out along the inclination of the wing 31 without being clamped; the wear-resistant plate 30 can limit the buckle piece 20 at the center when in use, and is beneficial to the sliding-out of the buckle piece 20 when in disassembly.
In summary, the pedal structure for one-sided pedaling of the road car can ensure that the cramp 20 is stable and does not slide backwards, and the step part 14 is used for assisting the cramp 20 to support; in addition, the first guide surface 1422 and the second guide surface 1423 are disposed to enable the cleat 20 to be smoothly removed by rotation, and the wing 31 of the wear-resistant plate 30 is further beneficial to the cleat 20 to slide out laterally. Therefore, the cramp 20 can be stably arranged on the pedal body 10, so that the cramp 20 is prevented from sliding when the cramp 20 is stepped on, but the cramp 20 is easy to be separated from the pedal body 10 when the pedal body is required to be detached.
