The fastening member 40' includes a plug-in The portion 41, the spring retaining portion 42 connected to the lower edge of the pivot portion 41 and the end portion of the tubular structure 32, is connected to the snap plate 43 at the top end of the pivot portion 41. The pivoting portion 41 has a pivot hole 41A extending through the left and right sides, and a pivot rod 41 coupled to the assembly portion 31 is pivoted to connect the pivoting portion 41 to the assembly portion 31. The fastening member 4 turns the angle of the tip rod 44 to a center. The open end 412 of the splicing portion 41 is in contact with the upper surface of the stop block 34. In the embodiment of the present invention, the tip end 44 is axially coupled by a first insertion end 441 and a second insertion end 442 to be closely engaged with the tip hole 311 of the assembly portion 31 of the pedal body 20. The outer ends of the first insertion end 441 and the second insertion end 442 extend through the pivot hole 411 of the fastening member 4 , and the fastening member 4 〇 can surround the first insertion end 441 and the second The tip 442 is rotated. The compression spring 53 is disposed in the tubular structure 32 and provides an elastic pushing force with respect to the spring/stop portion 42 of the fastening member 40. The adjusting component 50 includes an adjusting screw 51 and an adjusting sleeve 52. The adjusting sleeve 52 is located in the cylindrical structure 32; the wall surface of the cylindrical structure 32 and the relative position of the adjusting sleeve 52 have long slots 54 and bumps 55 that can be coupled to each other to ensure that the adjusting sleeve 52 is not The cylindrical structure 32 rotates. The first end of the adjusting sleeve 52 is a spring stopping portion 521, and both ends of the compression spring 53 abut against the two spring stopping portions 42 and 521, respectively. The second end of the adjusting sleeve 52 is provided with a threaded hole 522'. The adjusting screw 51 is locked into the threaded hole 522 from a predetermined through hole 321 of the end of the cylindrical structure 32. 201105545 By the above-mentioned adjusting component 50, a hand tool such as a screwdriver can be passed through the through hole 32 of the cylindrical structure & the head of the adjusting screw 51 can be contacted, and the hand screw is rotated by the hand screw W' The adjusting screw 51 and the working hole 522_ are oriented, and based on the feature that the adjusting sleeve 52 is closed in the cylindrical structure 32 and cannot be rotated, rotating the adjusting screw 51' in the - direction can make the adjustment money 52 Compressing the compression spring _ direction crane j and rotating the adjustment screw 51 ' in the opposite direction causes the adjustment sleeve 52 to move in the direction of the compression spring 53. Thereby, the rotation of the adjusting screw 51 is controlled to control the linear movement of the adjusting sleeve 52 in the cylindrical structure & the compression spring 53 is compressed or released, thereby changing the pre-force of the compression spring 53. Referring to the fourth and fifth figures, the adjustment method described in the above paragraph is shown in a combined cross section. Rotating "Xuan" Zhou t screw 51, so that the 彡 彡 adjustment sleeve 52 moves in the direction in which the cylindrical structure 32 is compressed to compress the compression spring 53 s. The compression magazine 53 is subjected to the above two spring attachment portions 521 42 Therefore, the retracting force of the secret spring 53 is increased, and the pressing force of the fastening member such as the spring stopper #42 is increased. The fastening member 4 is centered on the tip rod 44. And generating a swing in the direction of the arrow a to cause the fastening member 40 to be added to the combination of the rear attachment portion 62 (shown in the first to the third figures) of the cleat 6 of the pedal body 2 The tightening force. Conversely, controlling the adjustment sleeve to move away from the reverse direction of the compression spring 53 will lower the pre-force of the compression spring 53 and relatively loosen the fastener 40 for attachment. The fastening force of the portion 62 is fastened. Referring to the first to third figures, the rear attachment portion 62 of the shoe clasp 60 has a horizontal snap surface 62h lower than the top surface 601 of the shoe cleat 60. The top surface of the snap plate 43 of the member 40 is a lower inclined surface 431. The bottom surface is a horizontal snap surface 432. The shoe fastening piece 60 is coupled to the pedal body 2〇. The horizontal snap surface 432 of the snap plate 43 is engaged on the horizontal snap surface 621 of the shoe clasp 60. The following describes the case where the cleat 6 〇 is combined with the card pedal in the sixth 'seventh and eighth figures. As shown in the sixth figure, the front end of the shoe clasp 60 is extended into the bottom surface of the front buckle portion 21 in a downwardly inclined posture. As shown in the seventh figure, the rear attachment portion 62 is opposite to the lower portion of the snap plate 43. The inclined surface 431 is biased by a downward force. The fastening member 40 swings in the direction of the arrow B with the tip rod 44 as a center, and the compression stopper 53 is compressed by the spring stopper portion 42 to make the rear attachment portion 62. The shackle 43 is passed through. As shown in the eighth figure, the shovel clasp 60 is coupled to the pedal body 2, and the compression spring 53 releases energy to push the level of the shackle 43. The snap surface 432 is formed on the horizontal snap surface 621 of the thief shoe clasp 60. As described above, the elastic preload provided by the compression spring 53 is related to the tight engagement of the snap plate 43 with the rear attachment portion 62. When the compression spring 53 exhibits elastic fatigue over time (4) and the combined fastening force is weakened, the present invention can be used by the adjustment assembly 5〇 The pre-force of the compression spring 53 is increased, and the fastening force of the locking plate 43 to the rear attachment portion 62 is reproduced. The adjustment screw 51 of the adjustment component 5 is rotated by a screwdriver to adjust the compression bomb. The purpose of the elastic pre-stress of 箦53 is simple and simple, and it can be easily implemented by the manufacturer, and adjusted according to his own habits to the binding fastening force most suitable for his own use. However, the above-mentioned combined fastening force The above-mentioned stop block 34 and the open end 412 of the pivoting portion 41 are in contact with each other to prevent the fastening member 4 from being excessively biased toward the shoe cleat 60. The problem of pressing the rear attachment portion 62 is such a design that the problem that the shoe clasp 60 and the pedal body 2 are disengaged due to excessive engagement tightness can be avoided. Although the present invention is described in terms of a preferred embodiment, those skilled in the art can make various changes in the form without departing from the spirit and scope of the invention. The above embodiments are only used to illustrate the present case and are not intended to limit the scope of the present invention. Any modification or change that is not in violation of the spirit of the case will be applied to the patent.
