Embodiment 1
[0035] Such as figure 2 and image 3 As shown, in this embodiment, the pedal 1 is provided with more than nine rows of connecting through holes 4 arranged longitudinally along the pedal 1, wherein one row is connected at one end of the pedal 1, and the remaining eight rows of connecting through holes 4 are connected from the other end of the pedal 1. One end starts to be arranged inwardly, and the number of connecting through holes 4 in each row is two, and screws 5 are assembled in the connecting through holes 4 arranged in rows, and the foot guard 2 is installed on the first surface of the pedal 1 through the screws 5, The support plate 3 is installed on the second surface of the pedal 1 through the screw 5, and the first surface is opposite to the second surface, so that the foot block 2 and the support plate 3 are located on the opposite side of the pedal 1, and the foot block 2 and the support plate 3 are at the same height .
[0036] Such as figure 1 As shown, after ...
Embodiment 2
[0039] The difference between this embodiment and the first embodiment lies in that the connection structure of the pedal 1 , the foot guard 2 and the support plate 3 is different. Such as Figure 5 to Figure 8 As shown, the present embodiment is provided with 8 dovetail grooves 6 along its longitudinal direction on the pedal 1, and the dovetail grooves 6 are arranged along the transverse direction of the pedal 1 and its cross-section is big inside and small outside; There is a dovetail block 7 whose shape is compatible with the dovetail groove 6, and the dovetail block 7 is assembled in the dovetail groove 6.
[0040] The rest are the same as the first embodiment, and will not be repeated here.
Embodiment 3
[0042] Such as Figure 9 As shown, the difference between the present embodiment and the second embodiment is that the present embodiment adopts a "T" groove 8 instead of the dovetail groove 6 as the connection groove between the foot block 2, the support plate 3 and the pedal 1, and accordingly the foot block 2 And the dovetail block 7 on the support plate 3 is replaced by a "T" type block 9. All the other are the same as embodiment two.
[0043] certainly. In addition to using the above-mentioned dovetail groove 6 and "T" groove 8 as the connecting groove, other types of grooves can also be used as the connecting groove, as long as the cross section of the connecting groove is large inside and small outside, so that the connecting groove can be stuck Foot guard 2 and support plate 3 get final product.
[0044] In addition to the above, the installation structure of the foot guard 2 can also be different from the installation structure of the support plate 3, as long as th...
