为了使本发明的发明目的，技术方案及技术效果更加清楚明白，下面结合具体实施方式对本发明做进一步的说明。应理解，此处所描述的具体实施例， 仅用于解释本发明，并不用于限定本发明。
参照图1和图2，宠物牵引器，包括壳体10、转动连接于壳体10内的转盘20和卷绕在该转盘20上的牵引绳(没显示)；壳体10上分别设有绳出口11和手柄部12，牵引绳的一端从绳出口11伸出；壳体10上设有按钮组件控制牵引绳的收卷和释放；按钮组件包括锁止件30和按钮40；按钮40一端为按压部41，另一端为枢接部42，按压部41设于壳体10外，枢接部42转动连接于壳体10内，锁止件30枢接于壳体10内并位于枢接部42下方；并能驱动锁止件30转动卡持转盘20；按压按压部41，带动枢接部42转动，枢接部42推动锁止件30转动并卡持转盘20，使得转盘20不能转动放绳；释放按压部41，枢接部42反向转动复位，并释放锁止件30，锁止件30释放转盘20，从而使其能够转动放绳。
具体地，参照图2和图3，枢接部42内设有一容纳槽43，容纳槽43内设有一扭簧44；锁止件30的上端插入容纳槽43，下端32与转盘20上的卡齿22配合，扭簧44一端在容纳槽43内抵接锁止件30的上端，另一端抵持容纳槽43壁。按压按压部41，枢接部42随之转动，推抵扭簧44，扭簧44推动锁止件30转动并卡持转盘20，使得转盘20不能正向转动放绳；释放按压部41，扭簧44推动枢接部42反向转动，并释放锁止件30，锁止件30释放转盘20，从而使其能够转动放绳。
壳体10上设有一第一固定轴33，锁止件30枢接于该第一固定轴33。锁止件30上部凸伸出第一限位部31，第一限位部31容置于容纳槽43，并可在该容纳槽43内活动。具体地，容纳槽43的两侧槽壁挖设有一槽口45，第一限位部31的两端设置在槽口45中，并能在槽口45中滑动。扭簧44推抵或释放 第一限位部31，使其在容纳槽内滑动，带动锁止件30绕第一固定轴33转动，从而卡持或释放转盘20。
壳体10内还设有锁止限位部13，锁止限位部13位于锁止件30一侧，锁止件30在扭簧44的推动下转动至卡持转盘20时，锁止限位部13抵接锁止件30，限制其继续转动，从而使其不能脱离转盘20。
锁止件30下端32为一卡持部，转盘20上均布有卡齿22；卡持部与卡齿22相互配合。当锁止件30转动，使卡持部插入两卡齿22之间时，锁紧转盘20，使其不能转动，当锁止件30转动，使卡持部伸出两卡齿22之间时，释放转盘20，转盘20能够转动。
较佳地，卡齿22具有一弧形边221和一直边222，卡持部也具有一直边321和一弧形边322。两直边相互抵接时，转盘20不能转动，两弧形边相互抵接时，转盘20能转动。
较佳地，转盘20通过一转轴23枢接与壳体10内，转轴内设有一转盘扭簧(没显示)，当锁止件30卡持转盘20时，转盘扭簧推动转盘20反向转动收绳。反向转动时，卡齿22的弧形边与卡持部的弧形边配合，从而能够向转盘20外方向推动卡持部，实现反向转动，从而收卷牵引绳。
壳体10在转盘20外围设有一防护壳15，锁止限位部13设于该防护壳15上。
防护壳15在绳出口出设一缺口14，转盘20上的牵引绳经该缺口进入绳出口并伸出壳体10。
按压部41下方设有弹性件16。释放按压部41后，弹性件16推动按压部41复位。具体地，按压部41下设有一凸柱(没显示)，壳体10上设一第二限位部411，弹性件16一端固设有于第二限位部411，另一端套接于凸柱。外力 按压按压部41时，弹性件16压缩，释放按压部41后，弹性件16伸出复位，从而推动按压部41弹起。
参照图2和图3，按压部41上设有可滑动的拨动件50，壳体10上设有第三限位部18和第四限位部19，二者均可与拨动件50配合；按压并拨动拨动件50至第四限位部19，第四限位部19锁定拨动件50进而锁定按钮40，使得即使释放按压部41后，按压部41也不能弹起，按钮40通过扭簧44驱动锁止件30转动，锁止件30下端与转盘20上的卡齿22配合卡持，从而使得转盘20不能转动释放牵引绳。拨动拨动件50脱离第四限位部19，至第三限位部18处被限位，则按钮40的按压部41在弹性件16的作用下翘起，带动枢接部42转动，枢接部42释放锁止件30，锁止件30转动从而释放转盘20上的卡齿22，使得转盘20能够转动释放牵引绳。第三限位部18限位拨动件50，防止按压部41过度翘起。
具体地，按压部41上设有滑动槽46，滑动槽46的槽底面设有一通孔47，拨动件50具有一拨动部51，拨动部下设一连接部52，连接部上相对的两端分别凸伸出一凸舌53，两凸舌53分别与第三限位部18和第四限位部19配合。拨动部51上表面设有一软胶垫54，该软胶垫54上设有纹路。软胶垫使得拨动拨动部时更加舒服，不搁手。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，其架构形式能够灵活多变，可以派生系列产品。只是做出若干简单推演或替换，都应当视为属于本发明由所提交的权利要求书确定的专利保护范围。

- 根据权利要求2所述的宠物牵引器，其特征在于，所述壳体上设有一第一固定轴，所述锁止件枢接于该第一固定轴；所述锁止件上部凸伸出第一限位部，所述第一限位部容置于所述容纳槽，并可在所述容纳槽内活动。
- 根据权利要求3所述的宠物牵引器，其特征在于，所述容纳槽的两侧槽壁挖设有一槽口，所述限位部的两端设置在所述槽口中，并能在所述槽口中滑 动；所述扭簧推抵或释放所述限位部，使其在所述容纳槽内滑动，带动所述锁止件绕所述第一固定轴转动，从而卡持或释放所述转盘。
- 根据权利要求2-4任一项所述的宠物牵引器，其特征在于，所述壳体内还设有锁止限位部，所述锁止限位部设于所述锁止件一侧，所述锁止件在所述扭簧的推动下转动至卡持所述转盘时，所述锁止限位部抵接所述锁止件，限制其继续转动而脱离所述转盘。
- 根据权利要求1所述的宠物牵引器，其特征在于，所述转盘通过一转轴枢接于所述壳体内，所述转轴内设有一转盘扭簧，当所述锁止件卡持所述转盘时，所述转盘扭簧推动所述转盘反向转动，收卷所述牵引绳。
- 根据权利要求5所述的宠物牵引器，其特征在于，所述壳体在所述转盘外围设有一防护壳，所述锁止限位部设于该防护壳上。
- 根据权利要求1所述的宠物牵引器，其特征在于，所述按压部下方设有弹性件；所述按压部下设有一凸柱，所述壳体上设一第二限位部，所述弹性件一端固设有于第二限位部，另一端套接于所述凸柱。
