其中,触发构件5用于在不同类型的执行构件2在与握持构件1连接后,触发控制模块41,以实现控制电机12执行相应的工作模式。
在本实施例中,控制构件4安装于握持构件1内,触发构件5安装于执行构件2上,具体的,控制模块41包括但不局限于电路板,控制模块41可以通过设置按钮411的方式被触发构件5触发、也可以通过插头插座的方式被触发构件5触发、也可以通过触点触发的方式触发被触发构件5触发、也可以通过传感器感应的方式被触发构件5触发,在本实施例中,触发模块被安装于安装开口11处,并可以通过电线的连接方式与电机12连接。
在进一步的实施例中,如图5所示,按钮411为弹性复位按钮,当执行构件2在与握持构件1进行连接时,会通过触发构件5触发压缩按钮411,以实现控制模块41控制控制电机12执行相应的工作模式。当执行构件2在与握持构件1进行拆卸时,由于按钮411为弹性复位按钮,按钮411弹性复位,以实现控制模块41控制控制电机12复位初始的工作模式。
需要强调的是,本申请不对控制模块41和触发构件5的数量进行限定,通 过触发构件5与控制模块41之间的搭配,实现多种工作模式的搭配。
应当理解的是,控制模块41也可以安装于执行构件2内,此时,控制模块41可以通过信号连接的方式与电机12连接,同理可知,触发构件5被安装于握持构件1上。
具体的,触发构件5包括:
至少一个滑动件51,滑动件51可滑动的安装于握持构件1上;
连接环52,连接环52同轴固设于执行构件2的一端;
凸沿53,凸沿53固设于连接环52的自由端,用于在执行构件2与握持构件1连接后,驱使至少一个滑动件51滑动,以触发对应的控制模块41。
在本实施例中,连接环52呈环状,且连接环52一端可以通过焊接或栓接等固定方式与执行构件2连接,其中,凸沿53呈弧形条状,且凸沿53背离执行构件2的一侧设置有导向斜面,以对滑动件51起到导向的作用,减少滑动件51的碰撞磨损;在执行构件2朝安装开口11嵌入的过程中,凸沿53会与滑动件51背离控制模块41的一端抵触,并挤压滑动件51,使得滑动件51朝控制模块41靠近,直到滑动件51触发控制模块41,从而对控制模块41起到一个触发目的。
需要强调的是,本申请不对滑动件51的数量进行限定,可以一个滑动件51触发一个控制模块41,也可以多个滑动件51触发同一个或不同的控制模块41,只要能够实现触发电机12执行不同的工作模式即可,故不在阐述。
具体的,控制模块41和滑动件51均设置有2个,滑动件51与控制模块41一一对应。
在本实施例中,控制构件4被配置成2个,但在制造过程中,控制构件4和滑动件51的数量也可以其他。
具体的,凸沿53设置有至少一个用于供滑动件51嵌入的让位槽531。
在本实施例中,由于让位槽531的存在,使得触发的工作模式得到增加,也即是说,通过一个握持构件1,可以适配更多种执行构件2,例如有2个滑动件51,分别命名为A和B,当凸沿53配置有1个让位槽531,则有第一种工作模式:A滑入让位槽531,B被凸沿53挤压而触发对应的控制模块41、第二种工作模式:B滑入让位槽531,A被凸沿53挤压而触发对应的控制模块41;当凸沿53配置有2个让位槽531,则有第三种工作模式:A和B均滑入对应的让 位槽531,控制模块41根据A和B的状态被触发成第三种工作模式;应当理解的是,当凸沿53没有配置有让位槽531,则A和B均被凸沿53挤压而触发对应的控制模块41,从而进入第四种工作模式。
需要说明的是,本申请的让位槽531和滑动件51可以有3个、4个或以上,本申请不做具体限定。
具体的,触发构件5还包括安装于握持构件1内的导向座54,导向座54设置有至少一个滑动孔541,滑动孔541与滑动件51一一对应,用于限位滑动件51。
在本实施例中,导向座54可以通过栓接的方式与握持构件1固定连接,通过导向座54限制滑动件51窜动,使得滑动件51只能沿滑动孔541的方向滑动,同时,导向座54用于安装滑动件51,避免滑动件51与握持构件1出现分离。
具体的,连接构件3包括:
锁环6,锁环6安装于安装开口11内周侧;
至少一个第一限位块61,第一限位块61固设于连接环52的外周侧、与执行构件2之间形成第一滑动空间611、与凸沿53之间形成第一滑道612;
至少一个第二限位块62,第二限位块62固设于锁环6内周侧,用于在握持构件1和执行构件2发生预设角度转动后,卡紧于对应的第一限位块61的内侧,以阻碍握持构件1和执行构件2相互远离;
其中,第一滑道612用于供第二限位块62滑动,以供第二限位块62进入第一滑动空间611。
在本实施例中,锁环6呈环状,且锁环6安装于握持构件1的内部,在安装的时候,将第二限位块62滑入第一滑道612,然后驱使握持构件1和执行构件2发生预设角度转动,使得第二限位块62滑入第一滑动空间611内,此时,第一限位块61和第二限位块62的内侧抵触,也就是说,对握持构件1和执行构件2施加相互远离的力,第一限位块61和第二限位块62会起到阻挡的作用。
具体的,连接构件3还包括分别与锁环6和握持构件1连接的驱动组件63,用于驱使第二限位块62卡紧于第一限位块61,以实现阻碍握持构件1和执行构件2发生相对转动。
由于对握持构件1和执行构件2施加相互转动的力,第一限位块61和第二限位块62容易发生相对转动,所以在本实施例中,通过驱动组件63的存在, 可以阻碍握持构件1和执行构件2发生相对转动,需要说明的是,本实施例中出现的阻碍,并非阻止的意思。
具体的,第一限位块61设置有第一驱动斜面613,第二限位块62设置有第二驱动斜面621,驱动组件63包括:
第一弹性件,第一弹性件分别与锁环6和握持构件1连接,用于阻碍握持构件1和执行构件2发生相对转动;
第一拨动件637,第一拨动件637与锁环6连接,并伸出握持构件1的外侧;
其中,第一拨动件637用于驱使锁环6转动。
在本实施例中,第一驱动斜面613用于在执行构件2朝安装开口11靠近时与第二驱动斜面621贴合,且在执行构件2继续移动过程中,第一驱动斜面613通过第二驱动斜面621驱使锁环6转动,进而使得第二限位块62进入第一滑道612,此时,第一弹性件受到挤压,直到第二限位块62进入第一滑动空间611时,在第一弹性件的弹力回复作用下,第二限位块62会自动嵌入第一滑动空间611内,此时,第一限位块61和第二限位块62的内侧相互抵触,可以理解为,第一弹性件对锁环6起到复位的作用。
在本实施例中,握持构件1设置有供第一拨动件637转动的通孔,第一拨动件637起到转动锁环6的目的,在需要拆卸执行构件2时,转动第一拨动件637,带动锁环6、第二限位块62转动,使得第二限位块62自第一滑动空间611滑入至对准第一滑道612,然后将执行构件2朝外拔,完成执行构件2的拆卸,需要说明的是,此时锁环6在第一弹性件的带动下复位。
具体的,锁环6外周侧固设有限位柱64,第一弹性件为一端套设于限位柱64、另一端固设于握持构件1内侧的第一弹簧631,第一弹簧631沿第二方向延伸设置,第一限位块61在第一弹簧631处于正常伸缩状态时与第二限位块62处于卡紧状态。
在本实施例中,限位柱64呈7字型,限位柱64的一端固设于锁环6的外周侧、另一端延伸进入第一弹簧631的一端内部,通过这种方式,可以确保第一弹簧631可以和限位柱64起到连接的关系,当第一弹簧631处于正常伸缩状态(非压缩状态)时,第二限位块62进入第一滑动空间611并与第一限位块61的内侧抵触,而第一驱动斜面613和第二驱动斜面621贴合并产生相对滑动的过程,限位柱64挤压第一弹簧631,使得第一弹簧631处于压缩状态。
实施例二:
本实施例和实施例一的不同之处在于第一弹性件。
结合图12至图13,具体的,第一弹性件包括至少一个弧形弹片632和弧形配合块635,弧形弹片632一端固设于握持构件1内侧、另一端与锁环6的外侧具有滑入间隙633,弧形弹片632的内侧与锁环6的外周侧具有第一形变空间634;
其中,弧形配合块635固设于锁环6的外周侧,用于自滑入间隙633嵌入第一形变空间634,以实现阻碍锁环6转动。
在本实施例中,弧形配合块635可以一体成型于锁环6的外周侧,在握持构件1和执行构件2接合后,转动握持构件1或执行构件2,使得弧形配合块635自滑入间隙633滑入第一形变空间634内,在这个过程中,弧形弹片632受到挤压而发生形变,即,第一形变空间634变大,而当弧形配合块635完全进入第一形变空间634内后,弧形弹片632复位,实现对弧形配合块635的扣合目的,即,阻碍锁环6转动。
具体的,第一弹性件由2个弧形弹片632首尾相连,其中一个弧形弹片632的自由端固设于握持构件1的内侧,另外一个弧形弹片632的自由端固设有导向片636,导向片636与锁环6的外周侧形成滑入间隙633。
在本实施例中,通过2个弧形弹片632的配合使用,将弧形配合块635嵌入最里边的第一形变空间634内,减少弧形配合块635因为意外而滑出所有的第一形变空间634的情况发生;其中,导向片636起到导向的作用,有利于弧形配合块635嵌入第一形变空间634内。
实施例三:
结合图14至图15,本实施例和实施例一的不同之处在于连接构件3。

在本实施例中,抵接部73、形变部74和承接部75可以一体成型设置,以提高限位弹片71的结构强度,其中,抵接部73呈直线型,以提高抵接部73和握持构件1内侧的接触面积,从而提高对承接部75的支承作用;在本实施例中,第一按压块7的滑动方向与握持构件1的延伸方向相垂直。
在需要将执行构件2和握持构件1锁紧时,按压第一按压块7,通过承接部75驱使2个形变部74朝外扩张,使得第二形变空间76变大,此时,第三限位块72可以通过第二形变空间76,在执行构件2和握持构件1接合后,松开第一按压块7,2个形变部74复位,即第二形变空间76复位,实现形变部74对第三限位块72的锁紧作用,换言之,对执行构件2和握持构件1施加相反的力时,形变部74阻止第三限位块72移动,当需要拆卸执行构件2时,按压第一按压块7,再次驱使第二形变空间76变大,即可使得第三限位块72脱离形变部74。

具体的,第二弹性件83为一端固设于第二拨动件82、另一端抵触于握持构件1内侧的第二弹簧,第二弹簧沿第二方向延伸设置,第一卡块8在第二弹簧处于正常伸缩状态时与第二卡块81处于卡紧状态。
