具体实施方式
以下结合附图和具体实施例对本发明提出的一种植入体输送装置作进一步详细说明。根据下面说明，本发明的优点和特征将更清楚。需说明的是，附图均采用非常简化的形式且均使用非精准的比例，仅用以方便、明晰地辅助说明本发明实施例的目的。此外，附图所展示的结构往往是实际结构的一部分。特别的，各附图需要展示的侧重点不同，有时会采用不同的比例。
图1是本发明一实施例中的植入体输送装置的外管上设有指示刻度的结构示意图；图2是本发明一实施例中的植入体输送装置的部分结构示意图，其中，已拆卸一个半环壳体和一个子传动组件；图3是图2中A部分的局部放大图；
如图1～图3所示，本实施例中的一种植入体输送装置，包括导管组件1、固定结构2以及传动组件3。
其中，所述导管组件1包括内管12、套设在所述内管12上的外管13，其中，所述外管13和所述内管12之间的空间用于放置植入体(图中未示出)。所述外管13或所述内管12上设有拨片15。
所述传动组件3用于带动设有所述拨片15的所述内管12或所述外管13沿所述内管12的轴线的方向移动。
所述固定结构2上设有声音提示组件4，设有所述拨片15的所述内管12或所述外管13移动以带动所述拨片15移动至所述声音提示组件4上时，所述拨片15作用于所述声音提示组件4以发声。
本实施例中的植入体输送装置通过在所述内管12或所述外管13上设有所述拨片15，并在所述固定结构2上设有所述声音提示组件4，使得在设有拨片15的所述内管12或所述外管13移动以带动所述拨片15移动到所述声音提示组件4上时，所述拨片15作用于所述声音提示组件4，以使所述声音提示组件4发声。如此，医生在进行植入手术时，能够根据所述声音提示组件4发出的声响确定所述内管12或所述外管13移动后的位置。
进一步的，重点参图2所示，在本实施例中，所述植入体输送装置还包括连接件14，所述连接件14与所述内管12或与所述外管13固定连接。所述固定结构2环状设置并至少套设在所述连接件14上。
在本实施例中，所述植入体输送装置在将植入体输送至人体的预定位置并释放时，可通过沿所述内管12轴线方向移动所述内管12或通过沿所述内管12轴线方向移动所述外管13来释放所述植入体。在释放植入体时移动所述内管12还是移动所述外管13，在此不做具体限定。在本实施例中，以沿所述内管轴线12方向移动所述外管13为例进行说明。
继续参考图2所示，所述导管组件1还包括锥形头11，所述锥形头11与所述内管12的一端固定连接，所述内管12的另一端还连接有固定座5。在本实施例中，所述内管12和所述固定座5以及所述锥形头11可一体成型设计，也可通过固定件固定连接，或者可通过黏胶层粘接。此外，所述内管12可不伸入所述锥形头11和所述固定座5，只与所述锥形头11和所述固定座5的表面连接。或者，所述内管12也可伸入所述锥形头11和所述固定座5以与所 述锥形头11和所述固定座5固定连接。如此，所述内管12与所述锥形头11和所述固定座5之间的连接更牢固。所述内管12与所述锥形头11和所述固定座5的连接方式以及所述内管12是否伸入所述锥形头11和所述固定座5，在此不做具体限定，以实际情况为准。
此外，在本实施例中，所述连接件14环状设置且套设在所述外管13上，其中所述连接件14可与所述外管13一体成型，也可通过固定件或黏胶层与所述外管13固定连接。
进一步的，本实施例中的植入体输送装置还包括指示刻度6，所述指示刻度6设置在设有所述拨片15的所述外管13或所述内管12上，或者所述指示刻度设置在固定结构2上，或者，所述指示刻度6还可以同时设置在设有所述拨片15的所述外管13或所述内管12和所述固定结构2上。下面详细介绍所述指示刻度6设置在不同位置时的情形。
继续参照图1所示，在本实施例中，若所述拨片15设置在所述外管13上，且所述外管13带动所述拨片15移动，则所述指示刻度6设置在所述外管13上，其中，所述指示刻度6用于指示所述外管13的移动距离。具体的，所述指示刻度6可以指示所述外管13从刚开始移动的位置移动至其预定位置之间的移动距离；所述指示刻度6也可以指示所述外管13从所述拨片15刚开始作用到所述声音提示组件4上的位置移动至预定位置之间的距离，其中，所述距离指的是所述拨片15或所述外管13沿内管轴线方向的移动距离。本实施例中，通过在所述外管13上设置所述指示刻度6，进而使得所述外管13和所述拨片15的移动距离可以通过所述指示刻度6读取。这使得医生在进行植入手术时，能够清楚直观的得出所述外管13或所述拨片15的移动距离，进一步提升植入体植入人体的位置的准确性。此外，若所述拨片15设置在所述内管12上，且所述内管12移动带动所述拨片15移动，则所述指示刻度6设置在所述内管12上。所述指示刻度在所述内管12上的具体位置根据具体实际情况设定，在此不做具体限定。
图4是本发明一实施例中的植入体输送装置的固定结构上设有所述指示刻度的结构示意图。可选的，所述指示刻度6设置在固定结构2的外表面上。 具体的，请参图4并结合图2所示，所述声音提示组件4还可以设置在两个所述半环壳体21其中之一的沿所述内管轴线延伸的端部上，两个所述半环壳体21中的另一个的外表面上还可以设置有所述指示刻度6，且所述指示刻度6沿所述内管轴线延伸。在本实施例中，当两个所述半环壳体21中的另一个的外表面上设置有所述指示刻度6时，所述指示刻度6可以指示所述外管13从刚开始移动的位置移动至其预定位置之间的移动距离；所述指示刻度6也可以指示所述外管13从所述拨片15刚开始作用到所述声音提示组件4上的位置移动至其预定位置之间的距离，其中，所述距离指的是所述拨片15或所述外管13沿内管轴线方向的移动距离。在本实施例中，由于所述半环壳体21的外表面上设置有所述指示刻度6，故所述指示刻度6更靠近固定座5。因此，在医生做手术时，所述指示刻度6更靠近人眼，使得医生能够更清楚的读取所述拨片15和所述外管13的移动距离。
此外，在可选的方案中，指示刻度6还可以为两个，两个所述指示刻度6同时设置在所述半环壳体21和所述外管13上。这样，医生就可以根据实际需要选取位于两个不同位置处的所述指示刻度6其中之一对所述外管13的移动距离进行读取，如此一来，外管13的移动距离的读取更方便，更准确。
进一步的，继续参图2所示，所述导管组件1还包括拨片承载环16，所述拨片15设置在所述拨片承载环16上，所述拨片承载环16与所述连接件14套设在所述外管13朝向所述锥形头11的端部。
在本实施例中，所述拨片15为两个，两个所述拨片15以所述内管轴线为中心对称设置在所述拨片承载环16的两端。两个拨片15其中之一与所述声音提示组件4配合以作用在所述声音提示组件4上以发声。当所述指示刻度6设置在固定结构2上时，另一个所述拨片15用于与指示刻度6配合使用，以指示所述拨片15的移动距离。
此外，在本实施例中，所述拨片承载环16的内径大于等于所述外管13的外径。当所述拨片承载环16的内径等于所述外管13的外径时，所述拨片承载环16与所述外管13之间无间隙，以使所述拨片承载环16与所述外管13之间不发生相对位移。进一步的，在实施例中，所述拨片承载环16还可与所 述外管13固定连接，从而更进一步的防止拨片承载环16与所述外管13之间发生相对位移，以提升所述拨片15作用在所述声音提示组件4上给出的发声指示的准确性。具体的，在本实施例中，所述拨片承载环16和所述外管13的固定连接的方式可以包括：一体成型、螺接或胶接等，所述固定方式在此不做具体限定，以实际需求为准。
所述连接件14朝向所述固定座5的一端的外侧设有外螺纹。所述传动组件3环状设置且内壁设有内螺纹，以套设在所述连接件14上并与所述连接件14的外螺纹咬合，以使所述传动组件3和所述连接件14螺接，通过转动所述传动组件3可使所述连接件14前后直线运动。
下面结合图1～图3说明本实施例的所述植入体输送装置的工作过程。首先，将所述植入体放置在所述内管12和所述外管13之间的空间中；之后，将所述植入体输送装置设有锥形头11的一端伸入患者体内；然后，医生手握所述固定件5并转动所述传动组件3，以使所述传动组件3带动所述连接件14和所述外管13以远离所述锥形头11的方向沿所述内管轴线运动，直至使所述植入体从导管组件1露出，然后将植入体植入患者体内；其中，当所述外管13运动到预定位置时，所述连接件14上的拨片15作用于所述声音提示组件4上以发出声音。如此一来，医生根据声音提示即可知道所述外管运动到预定位置，从而进行预定操作。
在本实施例中，所述预定位置可以是植入体释放完成时对应的外管移动的位置，也可以是植入体释放到关键区域中时对应的外管移动的位置等，所述预定位置的具体含义在此不做具体限定，以实际情况为准。此外，在本实施例中，所述预定操作可以为对应于上述植入体释放完成时的停止操作，或者对应于所述植入体释放到关键位置时的速度放缓操作等。在本实施例中，所述预定操作在此不做具体限定，以对应于所述预定位置来定。
继续参照图1并结合图2所示，在本实施例中，所述固定结构2包括两个半环壳体21，两个所述半环壳体21以所述内管轴线为中心镜像(对称)可拆卸地套设在所述连接件14上，所述声音提示组件4设置在两个所述半环壳体21其中之一上。具体的，在本实施例中，其中一个半环壳体21沿所述内 管轴线延伸的端部上具有凹槽，所述声音提示组件4设置在所述凹槽内。如此一来，两个半环壳体21沿所述内管轴线延伸的端部的位置可形成空腔。在拨片15作用在声音提示组件4上发出提示声音后，提示声音可在空腔内震荡以增大提示声音的分贝。
在本实施例中，所述固定结构2包括两个半环壳体21，且两个所述半环壳体21可拆卸连接。基于此，在组装本实施例的所述植入体输送装置时，可将两个所述半环壳体21分开，然后将两个所述半环壳体21其中之一卡合在所述导管组件1的一侧上，之后将另一所述半环壳体21卡合在所述导管组件1的另一侧上，最后使用固定件固定两个所述半环壳体21，以完成固定结构2的组装。即，本实施例中的固定结构2的组装较为方便，且在两个半环壳体21其中之一受损时，可通过使两个所述半环壳体21脱离固定而对受损的所述半环壳体21进行更换，从而不用更换整个所述固定结构2，有利于降低植入体输送装置的成本。其中，两个半环壳体21之间可以采用螺丝或螺栓等进行固定，在此不做具体限定。
在本实施例中，所述传动组件3包括两个子传动组件31。两个所述子传动组件31以所述内管轴线为中心可拆卸地镜像(对称)套设在所述连接件14上。在组装所述传动组件3时，可将两个所述子传动件31分开，然后将两个所述子传动件31其中之一卡合在所述连接件14的一侧上，之后将另一所述子传动件31卡合在所述连接件14的另一侧上，最后使用固定件固定两个所述子传动件31，以完成传动组件3的组装。即，本实施例中的传动组件3的组装较为方便，且在两个子传动组件31其中之一受损时可通过使两个所述子传动组件31脱离固定而对受损的所述子传动组件31进行更换，从而不用更换整个所述传动组件3，有利于降低植入体输送装置的成本。其中，两个子传动组件31之间可以采用螺丝或螺栓等进行固定。在此不做具体限定。
图5是本发明一实施例中的植入体输送装置的声音提示组件安装在固定结构上的结构示意图；图6是本发明一实施例中的植入体输送装置的声音提示组件中的凸起设置在本体上的结构示意图。参图3并结合图5和图6所示，在本实施例中，所述声音提示组件4包括敲击体41，所述敲击体具有非光滑 的敲击面B。当所述拨片15移动到所述声音提示组件4上时，所述拨片15刮擦所述敲击面B以发声。其中，所述声音提示组件还包括第一固定件42，所述第一固定件42穿过所述敲击体41以将所述敲击体41固定在所述固定结构2上。具体的，所述第一固定件42将所述敲击体41固定在所述固定结构2的半环壳体21沿所述内管轴线延伸的一端的端面上。
进一步的，在本实施例中，所述第一固定件42弹性设置，所述拨片15对所述敲击体41施加作用力时，弹性设置的所述第一固定件42积蓄弹性势能并产生反向作用力，以使所述敲击体41在所述拨片15和所述第一固定件42的作用力下往复移动。具体的，在本实施例中，所述敲击体41在所述拔片15和所述第一固定件42的作用力下在垂直于所述敲击面B的方向往复移动。在可选实施例中，所述敲击体41在所述拨片15和所述第一固定件42的作用力下在与所述敲击面B呈一定较小夹角的方向斜向往复移动。可选的，所述第一固定件42可以设置为具有弹性功能的部件，所述具有弹性功能的部件在所述拨片15对所述敲击体41施加作用力时，积蓄弹性势能并产生相反作用力。可选的，所述第一固定件42可以设置为具有弹性功能的螺丝，所述具有弹性功能的螺丝在所述拨片15对所述敲击体41施加作用力时，积蓄弹性势能并产生相反作用力。可选的，继续参照图5所示，所述第一固定件42还可以分体设置，其中，所述第一固定件42可以包括：固定主体421和弹性件422。所述固定主体421穿过所述敲击体41以将所述敲击体41固定在所述固定结构2上，所述弹性件422套设在所述固定主体421上。如此，所述拨片15对所述敲击体41施加作用力时，所述弹性件422积蓄弹性势能并产生反向作用力，以使所述敲击体41在所述拨片15和所述弹性件422的作用力下在垂直于所述敲击面B的方向上下移动。
继续参照图5所示，在本实施例中，所述敲击体41包括本体411和设置在所述本体411上的多个凸起412，多个所述凸起412和所述本体411的顶表面构成所述敲击面B。在所述连接件14带动所述拨片15沿远离所述锥形头11方向运动以释放所述植入体，并在所述拨片15移动到所述声音提示组件4上时，所述拨片15与所述敲击面B刮擦，进而发出声响。
在本实施例中，多个所述凸起412与所述本体411顶表面构成所述敲击面B。在其他实施例中，所述敲击面B也可以为粗糙的面，所述敲击面B具体形态在此不做具体限定，以实际情况为准，只需在拨片15刮擦所述敲击面B时发声即可。
进一步的，继续参图3和图5～图6所示，具体的，在本实施例中，所述第一固定件42穿过所述敲击体41的本体411以将所述敲击体41固定在所述固定结构2上。所述本体411上设有容纳孔101，所述容纳孔101内设有限位块4111，所述限位块4111与所述容纳孔101的侧壁固定连接。所述弹性件422的一端伸入至所述容纳孔101中并与所述限位块4111抵接，以及所述弹性件422的另一端与所述固定结构2抵接。
在本实施例中，当所述拨片15移动到所述声音提示组件4上时，所述拨片15作用在所述凸起412上发声，同时使所述本体411朝向所述固定结构2(即，半环壳体21沿所述内管轴线延伸的一端的端面)方向运动。此时，所述弹性件422被压缩，积蓄弹性势能，待所述拨片15运动到相邻所述凸起412之间时，所述弹性件422产生远离所述声音提示组件4所在的半环壳体21的端面的应力进而推动所述本体411朝远离所述声音提示组件4所在的半环壳体21的端面的方向运动，进而使得所述拨片15与相邻所述凸起412之间的所述本体411的顶表面碰触而进一步的发出声音。本实施例中，所述弹性件422产生的弹性势能使得所述本体411在垂直于所述内管轴线方向往复运动，进而与所述拨片15震荡刮擦，以增大所述拨片15作用在所述声音提示组件4上时发出的声音分贝。这有利于医生根据所述分贝较高的声音判断所述外管13的移动位置。
在本实施例中，所述凸起412之间的间距可以相等，如此可使得拨片15作用在所述声音提示组件4上发出提示声音时，提示声音之间的间隔时间相同。同时，还可以使得至少部分所述凸起412之间的间距不相等，如此使得至少部分提示声音之间的间隔时间可以不相等，从而可通过间隔时间不等的提示声音判断外管13的移动位置。此外，凸起412之间的间距和凸起412的个数还可以根据不同需求进行调节。例如，若需要声音提示组件4断续发出 提示声音，则设置比较少数量的凸起412，并使相邻所述凸起412之间具有较大的间距，比如10cm范围内可以设置10个凸起；若需要声音提示组件4连续密集地发出提示声音，则设置比较多数量的凸起412，并使相邻所述凸起412之间具有较小的间距，比如10cm范围内可以设置20个凸起。
此外，在本实施例中，所述拨片15和所述凸起412的材质可以选用PC(聚碳酸酯)、ABS(丙烯--丁二烯--苯二烯的共聚物)等，所述拨片15和所述凸起412的材质在此不做具体限定，只要可以实现较轻的重量但又可以提供足够的弹性和耐磨性即可。
继续参照图3和图5～图6所示，本实施例中，所述固定主体421为螺丝，所述弹性件422为弹簧。在其他实施例中，所述固定主体421还可以为螺栓，所述弹性件422可以为具有弹性性能的物体，比如弹片或弹块等。
此外，在其他实施例中，所述弹性件422还可以不伸入所述容纳孔101，而是夹持在所述固定结构2和所述本体411之间。具体，以实际情况为准。
此外，在其他实施例中，所述第一固定件42还可以为弹性固定件，所述弹性固定件的至少位于所述本体411和所述固定结构2之间的部分弹性设置。所述第一固定件41的具体设置结构在此不做具体限定，只要能够使所述本体411沿垂直于所述内管轴线方向往复运动即可。
在上述实施例中，所述第一固定件42为固定本体431上套设弹性件422的组合结构。在其他实施例中，所述第一固定件42还可以只设置固定本体431，不设置弹性件422，以将所述本体411固定在所述固定结构2上即可。或者，在所述本体411和所述固定结构2之间设置黏胶层，以通过所述黏胶层固定所述本体411和所述固定结构2。所述本体411和所述固定结构2之间的固定方式不做具体限定，以实际需求为准。
图7是本发明一实施例中的植入体输送装置的另一结构示意图。在可选的方案中，连接件14还可以呈板状结构，且所述外管13和传动组件3均穿过所述板状结构。
具体的，如图7所示，在本实施例中，所述连接件14呈板状结构，且所述板状结构中开设有沿所述内管轴线延伸且贯穿所述板状结构的通槽102，以 及所述板状结构中开设有沿所述传动组件的轴线延伸且贯穿所述板状结构的螺孔(未图示)。所述外管13穿过所述通槽102并卡持在所述通槽102内，以及所述传动组件3穿过所述螺孔后与所述连接件14螺接。在本实施例中，所述外管13和所述传动组件3之间偏心设置，即，所述外管13和所述传动组件3不在同一直线上。
如图7所示，在本实施例中，所述连接件14为长方体，所述传动组件3为螺杆，所述螺杆一端伸入所述连接件14的所述螺孔内，远离所述连接件14的另一端设有电机33，所述电机33与所述螺杆通过联轴器34连接，所述电机33转动以带动所述螺杆转动，进而带动所述连接件14和所述内管13沿所述内管轴线方向远离或靠近所述锥形头11方向运动。
此外，在本实施例中，所述通槽102在垂直于所述内管轴线方向上贯穿所述连接件14，因此，所述导管组件1可以从所述通槽102贯穿所述连接件14的一端伸入或脱离所述通槽102以与所述连接件14连接或脱离所述连接件14。如此一来，所述导管组件1安装和拆除方便。其中，所述所述外管13可以通过螺接、抵接或者黏接等方式与所述连接件14固定连接，所述外管13和所述连接件14的具体连接方式在此不做具体限定。
进一步的，继续参照图7所示，在本实施例中，所述外管13上设有强度增强环7，所述强度增强环7套设在所述外管13上且至少部分卡合在所述通槽102内。在本实施例中，所述强度增强环7用于增强所述外管13上的强度，以防止所述外管13的与所述连接件14连接的区域在受力时断裂。在本实施例中，所述强度增强环7可与所述外管13一体成型设置，也可与所述外管13可拆卸设置。当所述强度增强环7与所述外管13可拆卸设置时，在所述外管13或所述强度增强环7其中之一损坏时，可只对损坏的所述外管13或所述强度增强环7更换，而不用对所述外管13和所述强度增强环7同时更换。以减小耗材损坏，降低成本。
继续参照图7所示，在本实施例中，所述强度增强环7上套设有两个间隔设置的凸环8，两个所述凸环8分别在所述通槽102的两端抵接所述板状结构，以用于防止所述连接件14和所述外管13在所述内管轴线上移动。所述 凸环8与所述强度增强环7可一体成型，也可通可拆卸连接。当所述凸环8与所述强度增强环7可拆卸连接时，在所述凸环8和所述强度增强环7二者其中之一损坏时，拆卸损坏的所述凸环8或所述强度增强环7进行更换即可，如此一来可降低成本。
进一步的，继续参照图7所示，在本实施例中，所述固定结构2板状设置。例如，所述固定结构2设置成矩形板。所述固定结构2的结构在此不做具体限定，设置为平面结构即可。所述声音提示组件4固定在所述板状设置的固定结构2上。可选的，在本实施例中，所述植入体输送装置还包括外壳(图未示)，所述固定结构2位于所述外壳内并与所述外壳的壳体固定连接。
图8是本发明一实施例中的植入体输送装置的声音提示组件安装在固定结构上的另一结构示意图。
进一步的，如图8所示，在本实施例中，所述第一固定件43可以包括固定主体431和弹性件432。所述第一固定件43的具体设置可参照如上所述的第一固定件42，此处不做详细描述。所述本体411上具有沿所述内管轴线延伸的第一滑槽103，所述第一固定件43穿过所述第一滑槽103，所述本体411在所述第一固定件43的限位下，沿所述内管轴线移动到预定位置后，固定所述第一固定件43以将所述本体411限制在所述固定结构2上方，从而使所述敲击体能够在所述弹性件432的弹性势能的作用下上下振动。在本实施例中，在将所述本体411固定到所述固定结构2上时，可先将所述第一固定件43的固定主体431穿过所述第一滑槽103对所述本体411进行预定位，之后沿所述内管轴线移动所述本体411以微调所述本体411，并在本体411移动到预定位置后拧紧所述第一固定件43(即，固定主体431在第一滑槽103内的位置固定)以将所述本体411固定在半环壳体21上。由于本实施例中所述本体411上设有沿所述内管轴线延伸的第一滑槽103，所述本体411在所述第一固定件43定位之后，可通过移动所述本体411使得所述第一固定件43在所述第一滑槽103内的位置可调，以对所述本体411的位置进行微调。如此一来，所述声音发声组件4的位置精度更精准，进而医生在进行植入体植入时操作更准确。或者根据所适配的瓣膜假体轴向长度需求来进行微调，以适配不同规格 的瓣膜假体。
进一步的，继续参图8所示，本实施例中的所述声音提示组件4还包括：位于所述本体411两侧的两个限位组件44，两个所述限位组件44设置在所述半环壳体21沿所述内管轴线延伸的端部上且位置可调，以在所述本体411安装到预定位置时，调整并固定所述限位组件44以在所述本体411的两侧对所述本体411进行限位。由于本实施例的所述植入体输送装置中设有限位组件44，且限位组件44在半环壳体21上的位置可调，故在所述本体411安装到预定位置时，固定所述限位组件44(即，限位件442在第二滑槽104内的位置固定)以使所述本体411在沿所述内管轴线方向不发生较大的晃动。
继续参图8所示，在本实施例中，所述限位组件44包括：限位件441和第二固定件442，所述限位件441上具有沿所述内管轴线延伸的第二滑槽104，所述第二固定件442穿过所述第二滑槽104，以在所述本体411安装到预定位置时固定所述限位件441。
具体的，继续参图8所示，在本实施例中，在将所述本体411固定到所述半环壳体21上时，可先将所述第一固定件43穿过所述第一滑槽103对所述本体411进行预定位；之后将所述限位件441放置在所述本体411两侧后将所述第二固定件442穿过所述第二滑槽104之后对所述限位件441进行预定位；最后沿所述内管轴线调整所述本体411的位置直至所述本体411安装到预定位置，并调整所述限位件441的位置，以在所述限位件441与所述本体411之间的距离调整到预定距离后拧紧所述第二固定件442，从而将所述限位件441固定在所述半环壳体21上并限定所述本体411沿所述内管轴线方向的位移，以防止所述本体411在所述内管轴线方向上发生较大晃动。
参照图8，在本申请的另一实施方式中，所述本体411的下方设置有一个滑动块，声音提示组件4连接到滑动块上，在固定结构2上设置有与滑动块对应的滑槽，滑动块被配置为可沿滑槽轴向移动，以此带动所述声音提示组件4移动。优选地，滑动块上设置有沿所述固定结构2周向向外的拨柄，以方便移动滑动块。在本实施实施方式中，利用滑动块将所述敲击体41和所述第一固定件42移动到预定发声位置，再固定滑动块。当所述拨片5与所述声 音发声组件4接触产生相对位移时，即可发出声响进行提示。如此，实现了仅通过移动滑动块来调整所述声音提示组件4的位置，操作更加简便。需要说明的是，本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。此外，各个实施例之间不同的部分也可互相组合使用，本发明对此不作限定。
上述描述仅是对本发明较佳实施例的描述，并非对本发明范围的任何限定，本发明领域的普通技术人员根据上述揭示内容做的任何变更、修饰，均属于权利要求书的保护范围。
