The element defined by the statement "includes a..." does not exclude the presence of another identical element in the process, method, article or device that includes the element.

[0018] The positioning clamp for bicycle lock pedal assembly, as shown in Figs. 1-2 The positioning seat 1 has a butterfly-shaped protrusion 4 on the upper end surface, and the butterfly-shaped hollow hole 3 in the middle of the lock piece 2 placed on the upper end surface of the positioning seat 1 is positioned and matched with the butterfly-shaped protrusion 4. The upper end surface of the positioning seat 1 is provided with two locking and fixing devices located on the same centerline and used for tightly fixing the lock piece 2 on the positioning seat 1. In the above structure, according to the structural characteristics of the lock piece 2, the butterfly-shaped protrusion 4 with two ends being fan-shaped and the fan-shaped end being transitionally connected to the concave trapezoidal shape is machined on the upper end surface of the positioning seat 1 to match the butterfly-shaped hollow hole in the middle of the lock piece 2, so as to realize the radial positioning of the lock piece 2 and ensure the stable and reliable radial position of the lock piece 2 during machining. On the basis of the radial positioning, the lock piece 2 is tightly fixed on the positioning seat by the locking and fixing device provided on the positioning seat 1, so as to realize the reliable axial positioning of the lock piece 2.

[0019] The specific structure of the locking fixing device is as follows: the locking fixing device comprises a pressing plate 5 and a bolt 6, two threaded holes 7 located on the same center line and on the outer side of the locking piece 2 are formed on the upper end surface of the positioning seat 1, the inner end of the pressing plate 5 is located above the locking piece 2, and the bolt 6 passing through the through hole on the pressing plate 5 is connected with the threaded hole 7, and the locking piece 2 is pressed and fixed on the positioning seat 1 by the pressing plate 5.

[0020] Since the locking piece 2 is provided with a larger chamfer at one end edge position and is a tapered section, when the tapered end of the locking piece 2 is upward, the locking piece 2 is not conducive to be quickly taken off from the positioning seat 1 due to the small thickness of the locking piece 2 itself and the influence of the tapered section, therefore, in order to facilitate the locking piece 2 to be taken off from the positioning seat 1, two notched grooves 8 located below the locking piece 2 are formed on the upper end surface of the positioning seat 1, and the two notched grooves 8 are located on the center line perpendicular to the center line where the two threaded holes 7 are located, the notch groove 8 is located at the outer edge position of the locking piece 2, and the notched groove 8 is used for quickly taking the locking piece 2 off from the positioning seat 1; when the locking piece 2 needs to be taken off from the positioning seat 1 after processing, the index finger and the thumb are located at the positions of the two notched grooves 8 respectively, and the locking piece 2 is pinched and lifted upward, so that the locking piece 2 can be quickly taken off, and the problem that the fingers cannot be smoothly lifted upward to take off the locking piece 2 due to the sliding off of the fingers along the tapered wall of the locking piece 2 is eliminated.

[0021] The positioning seat 1 is designed as a circular or polygonal structure in cross section according to the use requirement, as shown in the figure, the positioning block 1 in the scheme is a rectangular structure. Figs. 1-2

[0022] The technical scheme has simple structure, novel design, simplifies the processing procedure, provides reliable positioning and clamping conditions for chamfer processing of the two sides of the butterfly-shaped hollow hole 4 of the locking piece 2, solves the problems of large clamping difficulty and low processing efficiency of the locking piece 2, improves the processing efficiency, reduces the processing cost, and has high use value.
