盖板本体341上设置有卡槽，后盖板343上设置有与卡槽位置对应的第三 突伸块3431，第三突伸块3431与卡槽卡持设置。端盖组件34还包括设置在盖板本体341与后盖板343之间的端盖342，端盖342上设置有用以使得第三突伸块3431穿过的第三通孔3421。
请具体结合图16-17，手柄20具有与机头30连接的第一端部21、以及远离机头30且用于进风的第二端部22。第二端部22贯穿有线缆40以为手持式吹风机10整体供电。线缆40远离第二端部22的一端提供有插头(图中未示出)，插头可以提供到主电源或者电池组的电连接。
其中，线缆40包括载电导线(火线，live wire)和中性导线(零线，neutral wire)。可选地，线缆40以一股电线贯穿第二端部22后，在手柄20内部被分成至少两股电线。
手柄20具有握持外壳23以对手柄20内部的组件进行保护。握持外壳23从机头30延伸至第二端部22远离机头30的一端。线缆40穿过位于第二端部22位置处的握持外壳23进入手柄20。线缆40大体定位于第二端部22的中间处，向手柄20的内部中心延伸。示意性地，手柄20整体呈管状结构，且具有基本一致的直径。当然，手柄20也可以为其它形状，本实施例对此不作限定。可选地，为了保证使用者使用手持式吹风机10时的稳定性，握持外壳23的手柄20可以设置有防滑组件；或者，握持外壳23上手柄20的材料为防滑材料。
本实施例的手持式吹风机10还包括用以将外部气流引入至机头30的吸风组件24，该吸风组件24设置在手柄20内以将外部气流从第二端部22吸入并导向至机头30。该吸风组件24包括马达141和风扇，马达141和风扇可以一体化设置；或者，也可以可分开设置，本实施例对此不作限定。可选地，马达141可以是交流感应电机、串激式交直两用电机、或者是直流电机等，本实施例不对马达141的类型作限定。
当然，手柄20内还可以设置有其它组件，比如：用于对线缆40、触控组件和吸风组件24进行固定的固定组件等，本实施例在此不再一一列举。
综上所述：通过弹性件53使得触控组件与控制电路板组件35连接，触控快捷方便，且触控组件不占用空间；触控组件结构简单，制作工艺方便。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
