再请参阅图 5〜图 7所示， 其为一种包含以前述制造方法所制成迫紧件的卡 式踏板， 主要包含有：
一踏板轴 10 ;
一结合于该踏板轴 10而可绕着该踏板轴 10旋转的踏板本体 20， 该踏板本体 20 两端分别为一勾固端 21及一扣固端 22， 该勾固端 21为一中空框体， 且该扣固端 22 包含由踏板本体 20侧边向外延伸的枢接段 221 ; 且该扣固端 22于其内侧设有向内延 伸的卡固块 222; 以及
一以前述制造方法所制成的迫紧件 30， 该迫紧件 30包含：
一迫紧件本体 31， 其包含有一迫紧端 32及一轴接端 33; 其中， 该轴接端 33设 有一对枢接板 331， 该对枢接板 331可供穿设一枢杆部 34以供枢接于该等枢接段 221 处； 其中， 该枢杆部 34可为一对螺栓；
一弹簧调整片 40， 其设于该迫紧件本体 31的轴接端 33处， 且该弹簧调整片 40 具有一埋设部 41， 该埋设部 41嵌设于迫紧件本体 31内部， 该埋设部 41往两侧各延 伸设有一翼部 411 ;
一设于该枢杆部 34的扭转弹簧 50， 该扭转弹簧 50两端为一簧脚 51， 该簧脚 51 可卡固于该踏板本体 20的卡固块 222处， 其中， 该扭力弹簧 50的中段处转折设有一 穿设部 52; 以及

明了上述本案详细结构后， 以下针对本案的动作原理逐一详细说明： 如图 8所示， 本发明的卡式踏板主要用以搭配一自行车专用鞋的鞋扣片 90， 该鞋扣片 90具有前附着部份 91和后附着部份 92， 使用者使用时先将自行车专用 鞋置放于卡式踏板上， 并使得该鞋扣片 90的前附着部份 91插设入该勾固端 21， 再针对该后附着部份 92施力踩踏， 由于该迫紧端 32的上表面为一斜面， 得以使 该迫紧件 30受力向外转动， 以增加该勾固端 21与迫紧端 32的间距， 藉此， 如图 9所示， 该鞋扣片 90的后附着部份 92可顺利卡入于该迫紧件 30内， 并藉由该扭 转弹簧 50的弹性推抵力， 使该迫紧件 30回复至原位， 并使得该勾固端 21与迫紧 端 32可分别勾固住该鞋扣片 90的前附着部份 91和后附着部份 92，防止使用者骑 乘自行车时， 脚部不慎滑脱造成肌肉拉伤等意外。
再者， 由于该扭转弹簧 50的穿设部 52紧抵于调整片 62处， 当使用者欲调整 鞋扣片 90与卡式踏板的紧固程度时， 仅需转动该调整螺栓 61， 使调整片 62沿长 孔 431滑移， 以改变调整片 62施加于扭转弹簧 50的穿设部 52的预力大小， 即可 调整鞋扣片 90与卡式踏板的紧固程度。
本发明藉由将弹簧调整片 40至少一部分置入并定位于该迫紧件模具 1的成形 模穴 2内， 利于进行该迫紧件 30的射出成形加工时， 使该迫紧件 30与弹簧调整 片 40结合成一体， 藉此， 可减少该迫紧件 30的组装程序， 并简化该迫紧件 30的 形状构造， 以利于开模制造、 降低生产成本。
且该弹簧调整片 40的埋设部 41设有往两侧延伸的翼部 411， 其可加强该弹 簧调整片 40嵌设于该迫紧件本体 31的固定力量， 可确实防止因长久使用后脱落 的问题； 再者， 该弹簧调整片 40可为金属材质所制成， 再加上该补强肋 432可防 止弹簧调整片 40因受力而弯曲， 确实增加其机械强度、 耐磨耗能力以及增加产品 的可靠度。
虽然本案是以一个最佳实施例做说明， 但精于此技艺者能在不脱离本案精神 与范畴下做各种不同形式的改变。 以上所举实施例仅用以说明本案而已， 非用以 限制本案的范围。 举凡不违本案精神所从事的种种修改或变化， 倶属本案申请专 利范围。
