实施中，旋转组件具体用于能够带动拉片沿顺时针和逆时针两个方向进行任意角度的旋转。
这样，拉片能够沿顺时针和逆时针两个方向，以任意角度旋转。即拉片旋转的方向包括顺时针和逆时针，旋转的角度为任意角度，可以是360度循环旋转。拉片旋转方式灵活，具有创新含量，更具有娱乐性、观赏性和体验感。

具体的，转动预设角度为90度至180度之间任一角度。
实施例二
本申请的拉链用拉头，在实施例一的基础上，还具有如下特征。
关于旋转组件的结构，具有以下结构。
实施中，如图5和图6所示，旋转组件包括：
安装轴311，竖向固定在拉头底座100的上表面；
轴承312，轴承312的内圈套在安装轴311的外周面，且与安装轴311之间的配合为过盈配合；
安装套环313，安装套环313套在轴承312的外圈的外周面，且与轴承312的外圈之间的配合为过盈配合；
其中，拉片200与安装套环313连接，安装套环313和轴承312的外圈能够带动拉片200以轴承312的内圈和安装轴311为中心向顺时针和逆时针两个方向进行任意角度的旋转。
安装轴和轴承的内圈是固定为一体的，是不动的；安装套环和轴承的外圈 是固定为一体的，能够相对于轴承的内圈和安装轴以顺时针和逆时针两个方向进行任意角度的旋转。因为拉片与安装套环连接，使得拉片也能以轴承的内圈和安装轴为中心向顺时针和逆时针两个方向进行任意角度的旋转。旋转组组件通过简单的结构，实现了拉片在顺时针和逆时针两个方向进行任意角度的旋转。结构简单小巧，便于实现。
实施中，如图5和图6所示，安装套环313具有两个相对设置的安装套环轴孔；
拉片的与开放端相对的一端具有拉片避让缺口，拉片避让缺口的两个端部分别为拉片的拉片安装臂210，拉片安装臂210具有拉片安装臂轴孔；
旋转组件还包括拉片第一装配轴314；
其中，拉片第一装配轴314穿过拉片安装臂轴孔和安装套环轴孔，拉片第一装配轴314与安装套环313固定，拉片第一装配轴314和拉片安装臂轴孔之间为间隙配合使得拉片200能够以拉片第一装配轴314为转动轴在拉头底座的上表面转动。
这样，拉片的开放端能够拉片第一装配轴为转动轴在拉头底座的上表面转动。
实施中，如图1所示，旋转组件还包括：
内置型顶盖315-1，内置型顶盖315-1包括内置型顶盖盖板和连接在内置型顶盖盖板之下的内置型顶盖侧壁315-12，内置型顶盖盖板盖在安装套环313的上表面，内置型顶盖侧壁315-12盖在安装套环313的侧面；内置型顶盖侧壁315-12具有两个相对设置的内置型顶盖轴孔；内置型顶盖侧壁为环形或半环形；
内置型顶盖侧壁315-12位于安装套环313和拉片安装臂210之间，拉片第一装配轴314依次穿过拉片安装臂轴孔，内置型顶盖轴孔和安装套环轴孔， 使得拉片的开放端以拉片第一装配轴为转动轴向远离拉片的初始位置的方向转动至180度。
这样，拉片能够上下翻转。
作为一个可选的方式，如图2，图5和图6所示，旋转组件还包括：
外置型顶盖315-2，外置型顶盖包括外置型顶盖盖板和连接在外置型顶盖盖板之下的半环形的外置型顶盖侧壁315-22，外置型顶盖盖板盖在安装套环313的上表面，外置型顶盖侧壁315-22盖在拉片安装臂210的外侧；外置型顶盖侧壁315-22具有两个相对设置的外置型顶盖轴孔；
外置型顶盖侧壁315-22位于安装套环313和拉片安装臂210的外侧，拉片第一装配轴314依次穿过外置型顶盖轴孔，拉片安装臂轴孔和安装套环轴孔，使得拉片的开放端以拉片第一装配轴314为转动轴向远离拉片的初始位置的方向转动至预设角度。拉片的开放端以拉片第一装配轴为转动轴向远离拉片的初始位置的方向转动的预设角度为90度至180度之间任一角度。
这样，拉片能够向上抬起至预设角度。
半环形的外置型顶盖侧壁一方面遮盖拉片安装臂与安装套环的连接处，另一方面，半环形的外置型顶盖侧壁形成的缺口用于拉片伸出。这样，拉片第一装配轴基本被外置型顶盖包围住，整个拉链用拉头整体的结构更为紧凑，也更为美观。
实施中，如图5和图6所示，顶盖具有顶盖通孔315-3，拉头底座100具有第一锁止通孔110；顶盖包括内置型顶盖或外置型顶盖；
拉链用拉头还包括具有自复位功能的拉头第一锁止组件；拉头第一锁止组件安装在拉头底座100和顶盖之间，且拉头第一锁止组件的上端从顶盖通孔处露出；
其中，拉头第一锁止组件在其上端受到下压且扭转的力的作用时，拉头组 件的下端从第一锁止通孔110伸入到拉链用拉头配合的拉链处卡住，从而阻止拉链用拉头沿拉链的拉动，且拉头第一锁止组件在竖向方向内被锁定；拉头第一锁止组件在其上端受到下压且扭转的力的作用时，拉头第一锁止组件的下端复位，且头第一锁止组件在竖向方向内被解锁。
这样，通过按压和扭转从顶盖通孔处凸出的拉头第一锁止组件的上端，就能实现将阻止拉链用拉头沿拉链的拉动；再次按压和扭转就能实现拉头第一锁止组件的复位。
通过对拉头第一锁止组件的上端的下压，能够实现将阻止拉链用拉头沿拉链的拉动，即实现拉链用拉头的锁止；同时，通过对拉头第一锁止组件的上端的扭转的力的作用，实现将拉头第一锁止组件在竖向方向的锁定，即保持阻止拉头用拉头沿拉链的拉动。再次按压和扭转就能实现拉头第一锁止组件的复位。锁止和复位的方式简单易于操作。
实施中，如图5和图6所示，安装轴311是中空的安装轴，第一锁止通孔110设置在拉头底座100的上表面且位于安装轴311的中空部分；
顶盖通孔位于顶盖的盖板的中心位置。
这样，旋转组件和拉头第一锁止组件不是截然分开的两套器件，而是交叉设置的，有利于提高空间的利用率。使得拉链用拉头的结构更加紧凑。
实施中，如图5和图6所示，第一锁止通孔110是两个，安装轴311是带有缺口的安装轴；
如图5和图6所示，拉头第一锁止组件包括：

实现锁止的过程如下：
首先，第一锁止柱的上端被下压，并施加扭转的力的作用，带动第一锁止柱底端的锁止横向钩沿L形卡位孔的竖向孔向下移动，在此过程中，锁止横向钩的底端保持顶住锁止头的上表面，压着锁止头向下移动，第一复位弹簧被压缩，锁止头的长臂穿过第一锁止通孔，伸入到拉链用拉头配合的拉链处卡住；
然后，锁止横向钩下移到L形卡位孔的底部，锁止横向钩滑入到L形卡位孔的横向孔内，整个第一锁止柱保持该位置，即拉链用拉头保持锁止状态。
实现解锁的过程如下：
首先，第一锁止柱的上端施加反向扭转的力的作用，锁止横向钩离开L形卡位孔的横向孔，进入到L形卡位孔的竖向孔中，由于第一复位弹簧的复位作用，自带动第一锁止柱向上移动，使得锁止头的长臂退出述第一锁止通孔，拉链用拉头能够沿拉链拉动。
实施中，如图5和图6所示，拉头第一锁止组件还包括：
第一复位弹簧定位盲孔120，设置在拉头底座100的上表面且位置位于安装轴的中空部分之内；第一锁止通孔110是两个且对称设置在第一复位弹簧定位盲孔120的两侧；
第一复位弹簧321的下端固定第一复位弹簧定位盲孔120内。
第一复位弹簧定位盲孔的存在，便于第一复位弹簧在安装时的定位。
实施中，如图2和图5所示，柱形本体的上端具有锁止按钮324-2，锁止按钮324-2凸出于顶盖通孔，且锁止按钮的径向尺寸大于述柱形本体的径向尺寸。
锁止按钮的径向尺寸大于述柱形本体的径向尺寸，便于用户进行锁止和解锁操作。有娱乐性、观赏性和体验感，外观新颖，手感圆滑。
给用户一种既高贵、又好玩的拉头拉片。特别是喜欢追求差异化的时尚人群，更有吸引力。
也是符合当今时尚产品的市场需求，配套拉链的研发更具有独特性。

拉片的开放端以拉片第二装配轴为转动轴向远离拉片的初始位置的方向转动的预设角度为90度至180度之间任一角度。
这样，拉片能够向上抬起至预设角度。
半环形的第二上盖侧壁一方面遮盖拉片安装臂与旋转环的连接处，另一方面，半环形的第二上盖侧壁形成的缺口用于拉片伸出。这样，拉片第二装配轴基本被第二上盖包围住，整个拉链用拉头整体的结构更为紧凑，也更为美观。
