The adjustment assembly includes a first adjustment structure 11 mounted on the pedal 1, a second adjustment structure 21 mounted on the fixed base 2, and a locking component 3 for use with the first and second adjustment structures 11 and 21. When the locking component 3 is connected to the first locking point of the first and second adjustment structures 11 and 21, only forward pedaling of the pedal valve is possible. When the locking component 3 is connected to the second locking point of the first and second adjustment structures 11 and 21, the pedal 1 is fixed to the fixed base 2, and the pedal 1 provides a resting function. When the locking component 3 is connected to the third locking point of the first and second adjustment structures 11 and 21, only backward pedaling of the pedal valve is possible.

[0023] The following provides a further explanation of the specific structure of the aforementioned footrest, mounting base, and adjustment assembly.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the bottom front end of the foot pedal 1 has three vertically spaced mating holes I, which serve as the first adjustment structure 11; the top of the side plate of the fixed base 2 has three vertically spaced mating holes II, which serve as the second adjustment structure 21; the upper mating holes I of the first adjustment structure 11 and the upper mating holes II of the second adjustment structure 21 are aligned to form the first locking point; the middle mating holes I of the first adjustment structure 11 and the middle mating holes II of the second adjustment structure 21 are aligned to form the second locking point; the lower mating holes I of the first adjustment structure 11 and the lower mating holes II of the second adjustment structure 21 are aligned to form the third locking point.

[0025] Further options, such as Figure 1 , Figure 2 , Figure 3As shown, in the second adjustment structure 21, all three mating holes II are round holes 201. The upper mating hole I of the first adjustment structure 11 is an arc-shaped hole 101 with its opening facing upwards, the middle mating hole I of the first adjustment structure 11 is a round hole 102, and the lower mating hole I of the first adjustment structure 11 is an arc-shaped hole 103 with its opening facing downwards. The locking component 3 is a long rod structure. The locking component 3 passes through the middle round hole 201 of the fixed base 2 and the middle round hole 102 of the foot 1, thus connecting the foot 1 and the fixed base 2. The base 2 is fixed together; the locking component 3 is inserted into the upper round hole 201 of the fixed base 2 and the upper arc-shaped hole 101 of the pedal 1. The locking component 3 limits the upward movement of the front end of the pedal 1, and the front end of the pedal 1 can only move downward to realize the forward pedaling function; the locking component 3 is inserted into the lower round hole 201 of the fixed base 2 and the lower arc-shaped hole 103 of the pedal 1. The locking component 3 limits the downward movement of the front end of the pedal 1, and the front end of the pedal 1 can only move upward to realize the backward pedaling function.

[0026] Further options, such as Figure 1 , Figure 2 , Figure 3 As shown, the protruding part at the bottom front end of the foot 1 is composed of two opposing upright plates, and two holes arranged coaxially on the two upright plates form a mating hole I; the fixed base 2 has a U-shaped structure, and two holes arranged coaxially on its two side plates form a mating hole II.

[0027] Further options, such as Figure 1 , Figure 2 , Figure 3 As shown, the distance between the two side plates in the fixed base 2 is greater than the width of the two upright plates in the foot pedal 1, so that the two upright plates can fall into the two side plates; the three round holes on one side plate of the fixed base 2 are irregular holes for use with the locking component.

[0028] The following provides a further explanation of the specific structure of the aforementioned locking component.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the locking component 3 consists of a T-shaped rod 31 and a stop rod 32. The stop rod 32 is fixed to the rod part of the T-shaped rod 31 and the end near the head. After the rod part of the T-shaped rod 31 passes through the mating hole of the foot 1 and the fixed seat 2, the stop rod 32 falls between the foot 1 and the fixed seat 2 to axially limit the T-shaped rod 31.

[0030] Further options, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a support plate 22 for placing the locking component 3 is installed on the fixed base 2. The support plate 22 has an irregular hole to facilitate the passage of the rod part of the T-shaped rod 31 and the stop bar 32. The thickness of the support plate 22 is less than the distance between the stop bar 32 and the head of the T-shaped rod 31.

[0031] Further options, such as Figure 1 As shown, the foot tread 1 has a concave-convex surface with anti-slip function.

[0032] When using the aforementioned integrated pedal structure, the pedal and the mounting base each have three mating holes corresponding to the three positions where the T-shaped rod is inserted and fixed. When a resting function is needed, the locking component is fixed in the middle mating hole; when a forward pedaling function is needed, the locking component is fixed in the upper mating hole; when a backward pedaling function is needed, the locking component is fixed in the lower mating hole; and when both forward and backward pedaling are needed, the locking component is removed and placed on the support plate of the mounting base. This invention, through the adjustment of the locking component's position, ensures the multi-functional use of the pedal, saving time when replacing pedals and improving convenience.
