实施例一：
配合图1至图5所示，在本发明实施例一中，所述调节螺母2与安装座1周向限位配合而使得调节螺母2与安装座1不可相对转动，且调节螺杆3可上下移动，这样调节螺杆3的正反转动则使得调节螺杆3相应上下移动；而所述调节磁块5则固定在调节螺杆3上，使得调节磁块5随调节螺杆3的转动而上下移动；所述直滑式电位器6的滑动部61与调节螺杆3相连，且直滑式电位器6的滑动部61随调节螺杆3的上下移动而上下移动，这样直滑式电位器6的滑动部61便能随调节螺杆3的转动而上下移动，从而改变直滑式电位器6的阻值。
配合图3至图5所示，具体的，在本发明实施例一中，所述安装座1上设有上下贯穿的安装孔11以及位于安装孔11外侧的安装腔12，安装腔12通过一滑动孔13与安装孔11相通；所述调节螺杆3可上下移动的穿过安装孔12，所述调节螺母2插置于安装孔11中，调节螺母2与安装孔11周向限位配合而使得调节螺母2与安装座1不可相对转动；所述直滑式电位器6则安装于安装腔12中，直滑式电位器6的滑动部61可上下移动的穿过滑动孔13后与调节螺杆3相连。其中所述安装座1可由连接座101和连接套102上下拼接而成，连接座101上设有上孔111和所述安装腔12，连接套102设有下孔112，上孔111与下孔112对接形成所述安装孔11；而所述安装孔11可形成有一方形段111，所述调节螺母2外形则为与方形段适配的方形结构而使得调节螺母2与安装孔11周向限位配合。

配合图6至图10所示，在本发明实施例二中，所述调节螺母2可上下移动的配合于安装座1中，且调节螺母2与安装座1周向限位配合而使得调节螺母2与安装座1不可相对转动，这样调节螺母2随调节螺杆3的正反转动而上下移动；所述直滑式电位器6的滑动部61与调节螺母2相连，且直滑式电位器6的滑动部61随调节螺母2的上下移动而上下移动，这样直滑式电位器6的滑动部61便通过调节螺母2与调节螺杆3连动配合，使得直滑式电位器6滑动部61能随调节螺杆3的转动而上下移动，从而改变直滑式电位器6的阻值。
配合图8至图10所示，在本发明实施例二中，所述安装座1上设有上下贯穿的安装孔11以及位于安装孔11外侧的安装腔12，安装腔12通过一滑动孔13与安装孔11相通；所述调节螺杆3可上下移动的穿过安装孔12，所述调节螺母2可上下移动的配合于安装孔11中，且调节螺母2与安装孔11周向限位配合而使得调节螺母2与安装座1不可相对转动；所述直滑式电位器6则安装于安装腔12中，直滑式电位器6的滑动部61可上下移动的穿过滑动孔13后与调节螺母2相连。配合图8所示，其中所述安装孔11可以为一方形孔，而调节螺母2外形则为与安装孔11适配的方形结构而使得调节螺母2与安装孔11周向限位配合；配合图8和图9所示，而调节螺母2侧壁可设有一嵌槽21，直滑式电位器6的滑动部61嵌合于嵌槽21中而使得直滑式电位器6滑动部61与调节螺母2相连。
配合图7至图10所示，在本发明实施例二中，所述调节螺杆3通过拉线机构7与调节磁块5连动配合；所述拉线机构7包括卷线盘71和拉线72，所述卷线盘71配合在调节螺杆3上且卷线盘71与调节螺杆3同步转动，拉线72一端固定在固定在卷线盘71上，拉线72的另一端则与调节磁块5相连，这样调节螺杆3带动卷线盘71转动时，卷线盘71能通过拉线72拉动调节磁块5进行移动。
配合图8至图10所示，在本发明实施例二中，所述调节旋钮4和卷线盘71分别固定于调节螺杆3的上下两端上，其中调节旋钮4可通过螺钉41锁固在调节螺杆3上端上，而卷线盘71则与调节螺杆3下端螺接。
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。
