以下将结合附图进行详细描述。
参见图1至图3所示，图1是本实施例的筋膜枪的结构示意图，图2是本实施例公开的筋膜枪拆掉手柄和下壳之后的结构示意图，图3是本实施例公开的筋膜枪的第一剖视图。本申请的筋膜枪包括手柄10、机身20、按摩头30以及驱动机构70。
其中，手柄10用于人手握持，机身20与手柄10连接，机身20包括前端21和与前端21相对的尾端22；按摩头30靠近前端21设置；驱动机构70包括电机71和传动组件73，电机71通过传动组件73驱动按摩头30运动，电机71至少部分位于手柄10中，传动组件73位于机身20中；其中，电机71的轴线的远离手柄10的一端相对手柄10的延伸方向朝向靠近尾端22的方向偏置，以使筋膜枪的重心朝向尾端偏移，且按摩头30的朝向远离机身20的运动方向与手柄远离机身20的延伸方向呈钝角设置。可以理解的是，电机71轴线的远离手柄10的一端相对于手柄10的延伸方向朝向靠近尾端22的方向偏置的意思可指电机71的轴线的远离手柄10的一端相对手柄10的延伸方向偏转至手柄10延长线的靠近机身20的尾端22的一侧，且电机71的轴线与手柄10的延伸方向相交的设置方式，或者可指电机71的轴线相对手柄10的延伸方向偏移至手柄10延长线的靠近机身20的尾端，且电机71的轴线与手柄10平行的设置方式。
其中，如图1和图3所示，手柄10与机身20的分界线为P，需要说明的是，由于机身20与手柄10的连接部分为平滑过渡，不存在明显的分界线，只能做大致区分，该分界线P仅是为了能更清楚的理解本方案而示意的，并非绝对意义上的分界位置。
本实施例通过使电机71的轴线的远离手柄10的一端相对手柄10的延伸方向朝向靠近尾端22的方向偏置，可以使得筋膜枪的重心朝向机身20的尾端22偏移，与此同时，且按摩头30的朝向远离机身20的运动方向与手柄向机身20的延伸方向呈钝角设置，由此，可使得按摩头30的移动轴相对手柄10的延伸方向的夹角为钝角，相当于将按摩头30上扬设置，相比于按摩头30的轴向与手柄10的延伸方向垂直设置的筋膜枪，在握持时，手腕所需弯折的角度更小，能够减轻长期握持的酸痛感。按摩头30对手柄10上的冲击与手柄10的延伸方向非正交，因此落在手掌上的冲击力与手掌非正交，存在一夹角，因此落在手掌上的力有一部分沿平行于手掌的方向分解，对于手掌的直接冲击力有效减小。电机71的偏转使得手柄10相对延伸方向的轴线朝向手掌偏转，手柄10的重力更多地集中在手掌上，手柄10具有更好的抗震的效果，有效地防止了手局部冲击大而产生的手麻问题的发生。
此外，本申请的筋膜枪的重心朝向机身20的尾端22偏移，使用筋膜枪时，筋膜枪能够主动向用户的手掌压贴，可以平衡机身20的前端的转矩，握持更省力。
手柄10内设置有电池130以用于对驱动机构70以及其他的电性元器件进行供电，该电池130的延伸方向与手柄10的延伸方向相同。
电机71的轴线为电机的转轴的轴线。当电池130为一块块状电池时，电池130的轴线为电池的中心线(铅垂线)，圆柱电池则为轴线；当电池130为由多块块状电池所组成的电池包时，电池130的轴线可以为电池包的中心线(铅垂线)。例如，电池130为由两块圆柱电池所组成的电池包，电池130的轴线即为与两块圆柱电池的轴线的距离均相等的轴线；电池130为由三块圆柱电池所组成的电池包，电池130的轴线即为与三块电池的轴线所形成的三棱柱的外接圆柱的轴线；当然，电池130的形态还可以为其他，其轴线大致一起重心平衡的线即铅垂线为准。
具体地，本实施例中的手柄10呈柱状结构，该柱状结构的横截面积沿远离机身20的一端逐渐变小。也即是说，本实施例中的手柄10靠近机身20的一端较粗，远离机身20的一端较细，这与用户的手握紧的形状基本一致，即食指环绕形成的圈较小指环绕形成的圈小，更加方便用户握持，能够提高筋膜枪的使用舒适性。
可选地，本实施例中柱状结构例如可以是圆形柱状结构、还可以是棱柱 状结构或者其他异形柱状结构，如椭圆柱。
本实施例中的手柄10上设置有防滑部(图中未示出)，如此设置，能够提高手柄10的防滑性能，便于用户抓持。
可选地，该防滑部可以是防滑纹，还可以是防滑垫，还可以是防滑纹和防滑垫的结合。其中，防滑纹例如可以是凹凸型防滑纹、锯齿型防滑纹或者波纹型防滑纹，防滑垫例如可以是硅胶垫或者橡胶垫等。
进一步地，本实施例中的手柄10上还设置有用于对筋膜枪进行控制的开关按键110，将开关按键110设置于手柄10上，便于用户操作和使用。可选地，该开关按键110可以设置于手柄10的柱面上，还可以设置于手柄10的背离机身20的端面上。在本申请的其他实施例中，还可以将该开关按键110设置于机身20上。
参见图3所示，本实施例中的机身20包括上壳23和下壳24，其中，下壳24靠近手柄10设置，上壳23背离手柄10设置，实际加工的过程中，上壳23与下壳24可以一体设置，还可以分体设置后组装为一体。本实施例中以上壳23和下壳24分体设置的情况对本申请的构思进行详细阐述，将上壳23和下壳24分体设置，便于对机身20内部的结构进行组装和维护。可选地，本实施例中的上壳23和下壳24之间可以通过卡扣连接，还可以通过螺钉、铆钉、焊接、粘接等方式连接在一起。
在本申请的一些实施例中，机身20还可以包括左半壳和右半壳，这里的左右是以手柄10的左右进行划分的，或者还可以将机身20设置为三块或三块以上能够围设形成安装空腔的壳体等。
在本申请的一些实施例中，使机身20的尾端22凸出于手柄10的外侧边缘，或者使机身20的前端21凸出于手柄10的外侧边缘，或者同时使机身20的前端21和尾端22同时凸出于手柄10的外侧边缘。可以理解的是，本实施例中的手柄10的外周边缘是指围绕手柄10的轴线设置的外侧壁面的边缘。
由于本实施例中的机身20具有凸出于手柄10的外周边缘设置的前端21和/或尾端22，实际使用时，用户用手握持手柄10(参见图13所示)，凸出于手柄10的外侧壁面的前端21可以对用户的手指进行限位，凸出于手柄10的外侧壁面尾端22可以对用户的虎口进行限位，防止筋膜枪在手上出现移位或者滑脱的现象。
可选地，前端21凸出于手柄10外侧边缘的长度大于等于30mm，且小于等于60mm，例如30mm、40mm、50mm或者60mm等。由此可使得传动组件73在机身20的延伸方向上分布，且与手柄10连接在机身20的范围交叠，如此充分地利用了机身20的空间，且有效地缩减了机身20的前端21相对手柄10凸出的长度，前端21凸出于手柄10外侧边缘的长度大于等于30mm，且小于等于60mm既能够保证传动组件73具有足够的长度，保证其顺畅的传递力矩，又使得机身20的长度较小，按摩头30按压在人体上时手柄10与按摩头30的距离较近，按摩头30位置更稳定。
在本申请的一些实施例中，同时使机身20的前端21和尾端22同时凸出于手柄10的外侧边缘，且机身20的尾端22凸出于手柄10的外侧边缘的长度小于机身20的前端21凸出于手柄10的外侧边缘的长度，避免将尾端22设置得过长而容易与人体发生干涉。
进一步地，本实施例中的手柄10包括与机身20连接的连接段，该连接段的横截面积逐渐增大，以使得手柄10与机身20形成平滑过渡连接，实际安装时，电机71至少部分位于连接段中。当电机71的轴线相对于手柄10的延长线朝向机身20的尾端22偏置时，机身20与手柄10之间通过限位弧面过渡连接，还能够增大机身20与手柄10交界处的空间，便于与朝向机身20的尾端22倾斜设置的电机71相匹配，提升机身20以及手柄10中的空腔利用率，有效地缩减筋膜枪的机身20的尺寸。
连接段的外表面形成限位弧面100，即机身20与手柄10之间通过限位弧面100过渡连接，这使得机身20与手柄10的拐角位置不会出现尖锐的夹角，用户的手握持手柄10时，不会对手指和虎口造成夹持和压迫感，更不会出现疼痛现象，能够提高筋膜枪的使用舒适性。此外，限位弧面100能够限制人手朝向机身移动，解决了高频冲击时人手在手柄上向机身20窜动，存在的机身压手的问题，缓解了筋膜枪高频振动时，机身20对手的压迫感。
进一步地，本申请的按摩头30包括连接端32和按摩端头31，其中，连接端32例如可以是连接柱，连接卡扣等，该连接端32通过传动组件73与电机71驱动连接，按摩端头31朝向远离机身20的前端21的方向设置，电机71工作时，能够带动按摩头30朝向靠近或者远离机身20的方向往复运动，便于对用户的软组织进行按摩，能够对软组织进行舒缓。
示例性地，电机71的轴线相对手柄10的延长线朝向机身20的尾端22 的方向偏转大于等于5°，且小于等于30°，如图2中的夹角B所示。例如电机71的轴线相对手柄10的延长线朝向机身20的尾端22的方向偏转角度为5°、10°、15°、20°25°或30°等。使电机71的轴线相对手柄10的延长线朝向机身20的尾端22偏转大于等于5°，且小于等于30°，能够提高用户的握持舒适度，又不至于使电机71因电机71偏转角度过大而造成筋膜枪重心偏移过大而影响按摩头30在用户手上的有效压持。
本申请中的筋膜枪还包括活塞60，该活塞60设置于机身20的前端21，按摩头30的连接端32与活塞60连接，电机71与活塞60驱动连接，便于驱动活塞60运动，进而驱动按摩头30沿靠近或者远离机身20的方向进行往复运动，进而便于对用户的软组织进行舒缓。可选地，活塞60的轴向垂直于电机71的轴向，而电机71与电池130不共轴，而此时的电机71的轴线相对于电池130的轴向朝向机身20的尾端22偏置的，即此时活塞60的轴向与电池130的轴向以及手柄10的延伸方向之间的夹角为钝角，活塞60相对于手柄10呈上扬设置的方式，而按摩头30是连接于活塞60并与活塞60同轴设置的，从而可以使得按摩头30相对手柄10上扬，用户握持手柄10时，视觉上可以更直观地观察到按摩头30，便于提升用户的使用舒适度。此外，电机71的轴线相对于电池130的轴向朝向机身20的尾端22偏置，活塞60相对于手柄10呈上扬设置的方式，还可以后拉活塞60的位置，使得活塞60在手柄10的单侧伸出的长度缩短，筋膜枪的机身20的前端21悬臂缩短，重心后移，使得筋膜枪向手部压持，握持更省力。
在本申请的一些实施例中，活塞60的轴线方向与电池130的轴线方向(即手柄10的延长方向)呈钝角设置，参见图2中的夹角A所示，也即活塞60相对于电池130的轴线方向上扬，这样，筋膜枪的按摩头30沿活塞60的轴线方向往复运动，可以对用户的不同部位进行捶打，此过程中，机身20会随同按摩头30沿活塞60的轴向，即与手柄10呈钝角的方向发生振动，机身20振动时给予手部的振动力为倾斜于用户的手掌，即机身20振动时给予手部的垂直振动力较小，筋膜枪握持感更舒适，便于降低用户手部长期握持的疲劳度。同时，活塞60相对于电池130的轴线方向上扬，还能够使得传动组件73的长度一定时，按摩头30与手柄10的距离更近，从而能够使得按摩头30按压在人体上时，筋膜枪朝机身20两侧的偏摆力臂更小，按摩头30的压贴效果更好，同时上扬设置的按摩头30能够使得手柄10对手掌的振动倾斜 地落在手掌上，缓解手掌的振动。
示例性地，本实施例中的活塞60的轴线方向与机身20的延伸方向相同，且机身20的延伸方向与手柄10的延伸方向呈钝角A设置，该钝角A大于等于95°，且小于等于120°，例如95°、100°、110°或者120°等。在此范围内，钝角A的范围较为合理，钝角A角度过小，起不到较为明显的连杆增长作用，钝角A过大会导致手柄10受到较大的轴向冲击，不利于握持。
如图3和图4所示，电机71和电池130安装好之后，该电机71与该电池130在第一截面上不共轴(如图3所示的截面即为第一截面)，在第二截面上共轴(如图4所示的截面即为第二截面)，第一截面为机身20与手柄10的中分面，且机身20与手柄10各自相对该中分面对称，第二截面与第一截面垂直，且第二截面同时穿过手柄10与机身20。可以理解的是，该电机71与该电池130在第二截面上共轴是指视觉上的共轴，而并不是指两者在空间上共轴的意思。如此设置，可以使得电机71与电池130位于筋膜枪的机身20的中间位置处，保证筋膜枪的重心位于筋膜枪的中分面上，防止筋膜枪的重心朝向中分面的两侧发生偏斜而产生偏转，便于用户握持和使用。
参见图3至图5所示，本实施例中的驱动机构70还包括支架72、传动组件73、减震组件以及紧固件75。
具体来说，支架72包括安装部721和连接部722，连接部722用于与机身20和/或手柄10，具体可以连接于机身20处，还可以连接于手柄10处，或者连接于机身20与手柄10相交接处，且手柄10的延伸方向垂直于连接部722，电机71安装于安装部721，电池130的延伸方向与连接部722垂直，该安装部721相对连接部722偏置，以使得电机71安装于安装部721时相对电池130偏置。如此设置，可以使得连接部722与电池130的端面平行，该安装部721与电机71的端面平行，相当于电机71斜置，但电机71的安装方式为直挂，此种安装结构，使得电机71能够更靠近机身20的背离按摩头30的一侧，机身20内部空间利用更充分，筋膜枪的机身20的形态更小，同时使得筋膜枪的重心朝向机身20的尾端22后移动更多，握持体验进一步提升。安装部721的安装平面7211与连接部722的端面所呈的夹角与电机71相对电池130偏转的角度相等，能够进一步提升筋膜枪的空间利用率。
进一步地，手柄10的延伸方向与连接部722的连接方向相同，安装部721的安装方向相对连接部722的连接方向偏置，以使得电机71安装于安装 部时相对手柄10的延伸方向偏置，进而可以使得筋膜枪的重心朝向机身20的尾端22偏移，使用筋膜枪时，筋膜枪能够主动向用户的手掌压贴，可以平衡机身20的前端的转矩，握持更省力。本申请中的连接部722的连接方向是指：连接部722与机身20的接合方向，具体地，如果连接部722与机身20采用螺钉、销钉、铆钉等紧固件连接时，螺钉、销钉、铆钉等紧固件的轴向即为连接方向，如果连接部722与机身20之间采用卡扣、焊接、以及粘接方式连接时，连接方向为连接部722与机身20的接触面的垂线方向。该连接方向能够决定驱动机构70安装在机身中时驱动机构70整体的偏置方向，进而决定电机71的偏置方向，即只要是连接部722与机身20连接好之后能够使得电机71相对手柄10的延伸方向偏置的连接方向均包含在本申请定义的连接方向的范围内。
在本申请的一种可选的实施例中，电机71位于手柄10内，且支架72固定于手柄10与机身20的交接处，电机71到机身20的前端21的距离大于电机71到机身20的尾端22的距离，也即是说，本实施例中的电机71更靠近机身20的尾端22设置，能够进一步提升筋膜枪的空间利用率。与此同时，机身20的尾端22凸出于手柄10的外侧边缘，能够在机身20的尾端22围设出一定的空间，驱动机构70的至少部分结构向尾端22中延伸，具体地，支架72延伸至尾端22，便于提高驱动机构70的空间利用率，尾端22处的空间能够与朝向尾端22设置的驱动机构70相适配，能够更好地容置驱动机构70。
为了便于对支架72进行定位和安装，本实施例中的限位弧面100上设置有连接柱120，支架72套设在连接柱120上，并通过紧固件75固定于连接柱120上，本实施例中间连接柱120设置于限位弧面100上，一方面便于进行连接柱120的设置，长在限位弧面100上的连接柱120可以设置得更短，具有更好的结构强度，以及注塑稳定性和精度，另一方面还便于对支架72进行支撑和定位。示例性地，本实施例中的紧固件75可以是螺钉、销钉、铆钉、销轴等。
具体地，本实施例中的连接部722可以为一块板状结构，还可以为其他异形结构。连接部722上设置有定位孔7221，该连接部722通过该定位孔7221连接于连接柱120，结构简单，稳定可靠。
可选地，本实施例中的连接部722上设置有多个定位孔7221，对应地， 连接柱120也设置为多个，例如，定位孔7221和连接柱120可是2个、3个、4个或者4个以上。本实施例中以4个为例进行说明，其中4个定位孔7221分别设置于连接部722的四个角上，能够稳定地将支架72固定于连接柱120上，结构更加稳定。
参见图3至图6所示，本实施例中的安装部721背离电机71的一侧设置有定位槽723，电机71的电机轴从安装部721穿设至定位槽723内；而传动组件73连接于电机71背离电池130的一侧，此时，传动组件73相对于电机71更加靠近机身20，能够合理利用机身20的内部空间。
传动组件73包括凸轮732和连杆731，该凸轮732与电机71的电机轴连接，且凸轮732的至少部分位于定位槽723内，连杆731连接于凸轮732。如此设置，可以使得传动组件73和活塞60更靠近手柄10，机身20的厚度得到了有效的减薄，可以使得机身20的尺寸有效减小，连接部722上抬，在上壳23中的深度更浅，更容易安装。
进一步地，本实施例中的连杆731沿机身20的前端21至尾端22的方向延伸，且该连杆731与手柄10的延长线相交，可以理解的是，手柄10的延长线是指手柄10的轴线的延长线。本实施例中使连杆731沿前端21至尾端22的方向延伸并与手柄10的延长线相交，连杆731的中心更加靠近手柄10，能够减小连杆731单侧凸出于手柄10的长度，从而可以缩短机身20的前端21悬臂，握持更省力。
本实施例中的连杆731为直连杆，该直连杆相对折弯连杆能够减少连杆731的空间占用率，便于实现筋膜枪的小型化设计。该直连杆位于机身20的轴线上，直连杆731往复运动时不容易与机身20的内侧壁面发生干涉，运动更加平稳。
具体组装时，凸轮732与电机71的电机轴通过螺钉、销钉等结构固定连接在一起，连杆731的第一端通过连接轴等连接在凸轮732上，连杆731的第二端连接于活塞60，且该连杆731与电机71的轴线方向垂直，按摩头30的连接端32与活塞60连接，电机71工作，可以带动凸轮732转动，进而可以带动连杆731、活塞60以及按摩头30沿机身20的内外方向往复运动，结构简单，空间利用率高。
由于连杆731长度对其输出的按摩力度相关，若与活塞60连接的连杆731的长度较短，输出力矩较小，无法满足按摩需求，且连杆731长度若较 小，当活塞60受到一定的阻力时，电机71在旋转方向上的阻力也较大，更容易憋死，因此连杆731的长度要足够长，由此导致了机身20也要足够长，本申请通过后倾电机71能够使得筋膜枪的重力分配更合理，握持更省力。
如前文所述，本实施例中的活塞60的轴向与电池130的轴线方向呈钝角设置，且该连杆731与电机71的轴线方向垂直，即活塞60以及连杆731均相对于电池130的轴线方向上扬，在与手柄10轴向垂直的方向上，等长度的机身20能够容置更长的连杆731，便于提升活塞60的力矩，使得筋膜枪具有更大的捶打力度。
进一步地，本实施例中的电机71包括转子712设置于转子712外侧的定子713，定子713安装于安装部721的安装平面7211上，该定子713靠近支架72的一端设置有接线端711，便于与电池130实现电连接以对电机71进行供电。
可选地，本实施例中的电机71为无刷电机，体积小，便于实现筋膜枪的小型化设计。
请一并参见图1至图6所示，可选地，在本申请的其他实施例中，驱动机构70包括电机71、传动组件73和支架72，其中，电机71通过传动组件73驱动按摩头30运动，至少部分的传动组件73位于机身20中，支架72包括安装部721和连接部722，连接部722用于配置为与机身20和手柄10中的至少之一连接，电机71安装于安装部721，手柄10的延伸方向与连接部722的连接方向相同，安装部721的安装方向相对连接部722的连接方向偏置。如此设置，可以使得电机71安装于安装部721时相对手柄10的延伸方向偏置，进而可以使得筋膜枪的重心朝向机身20的尾端22偏移，使用筋膜枪时，筋膜枪能够主动向用户的手掌压贴，可以平衡机身20的前端的转矩，握持更省力。本实施例中的电机71、传动组件73以及支架72的具体结构前文已经介绍过，此处不再赘述。
请一并参阅图3、图7和图8所示，为了便于对驱动机构70进行减震，本实施例中的支架72或者电机71通过减震组件连接在机身20和/或手柄10中，本实施例中以支架72通过减震组件连接在机身20与手柄10向交接处为例进对本申请的构思进行说明。具体地，本实施例中将减震组件设置于连接柱120和连接部722之间，具体设置于连接柱120和定位孔7221之间，该减震组件将驱动机构70的振动与机身20或者手柄10的内壁进行有效隔绝，一 定程度上抑制了机身20和手柄10的振动。在本申请的其他实施例中，减震组件还可以设置于支架72的用于与机身20或者手柄10接触的表面上。
在本申请的一些实施例中，减震组件包括多个减震件74，该减震件74夹设在连接柱120和定位孔7221之间，具体地，该减震件74、连接柱120与定位孔7221三者一一对应地设置，该减震件74用于隔绝支架72与连接柱120之间的刚性接触，便于提高减震组件的减震效果。
进一步地，本实施例中的减震件74的端部具有止挡于定位孔7221的两端的减震外凸缘741，当将该减震件74安装于定位孔7221内之后，该减震外凸缘741能够用于将减震件74限定在定位孔7221内。与此同时，该减震外凸缘741还能够将连接部722与限位弧面100隔离开，能够进一步提高减震组件的减震效果。示例性地，减震外凸缘741可以是圆环凸缘，还可以是方环凸缘或者其他异形凸缘等。
为了便于将减震件74夹设固定在定位孔7221和连接柱120之间，本实施例中的减震件74呈空心柱状结构，实际安装时，该空心柱状结构过盈配合的方式安装于定位孔7221，连接柱120穿设于空心柱状结构内。如此设置，可以使得支架72上的减震件74能够与连接柱120形成柱面配合，减震外凸缘741与连接柱120的端面形成端面配合，通过减震件74的过盈配合，实现支架72与连接柱120的固定。实际组装时，紧固件75穿设于减震件74以用于将支架72固定于连接柱120，该紧固件75用于提供与连接柱120的端面相对的端面，从而限制支架72向背离连接柱120的方向移动，完全限定支架72的自由度。与此同时，紧固件75的端面与支架72的端面之间还设置有减震外凸缘741，能够提高紧固件75的紧固效果，并能提高减震组件的减震效果。
可选地，本实施例中的减震外凸缘741与减震件74一体成型设置，结构强度高，能够提高本申请的减震组件的使用寿命和稳定性，并能够简化筋膜枪的组装工序。当然，在本申请的其他实施例中，减震外凸缘741还可以独立于减震件74设置。
示例性地，本申请中的减震件74为橡胶件，具有较好的吸收振动，减小噪声的作用。在本申请的其他实施例中，减震件74还可以设置为尼龙件或者硅胶件等。尼龙件和硅胶件具有一定的吸收振动的效果，同时又具有较好的耐磨性，在长期摩擦后不会使得配合间隙增大而使得电机71晃动产生更大的 噪声。
进一步地，该空心柱状结构的内侧壁面上设置有沿空心柱状结构的轴向延伸的凸条742和凹槽743中至少之一。如此设置，减震件74夹持在连接柱120与定位孔7221之间时，具有较大的形变量，进一步具有较好的减震效果。可选地，该凸条742和凹槽743至少之一为多条，例如两条、三条、四条或者四条以上，具体根据实际的安装需求进行设置。
参见图9和图12所示，本实施例中的支架72位于电机71背离手柄10的一侧，从而使得电机71更加靠近电池130，由此使得筋膜枪的重力更多地集中在手柄10上，提升手柄10的稳定性，降低手柄10的震感。
由于将电机71朝向电池130设置，而电机71的定子713固定在支架72上，安装好之后，定子713位于转子712的背离电池130的一侧，连接电池130和电机71的接线端711的导线40需要绕过电机71的转子712与绕组相接，为此，本实施例中的电机71与手柄10的内侧壁面之间具有过线间隙80，实际组装时，电机71与电池130通过设置于该过线间隙80内的导线40连接，通过该过线间隙80将电池130与电机71连接，结构简单，组装方便。
进一步地，本实施例中的筋膜枪还包括隔挡件90，该隔挡件90固定于手柄10的内侧壁面，该隔挡件90与手柄10和电机71均间隔设置，也即是说，该隔挡件90与电机71和机身20之间均间隔有一定距离，实际安装时，导线40穿插在隔挡件90与手柄10的内侧壁面之间。如此设置，隔挡件90能够对导线40的位置进行限位或隔挡，有效地防止导线40与电机71的除去接线端711的部位接触，保证导线40的连接稳定性。实际安装时，隔挡件90设置于手柄10的内侧壁面与电机71之间，导线40设于隔挡件90与手柄10的内侧壁面之间。如此设置，可以使得隔挡件90将导线40与电机71隔挡，避免了导线40与电机71除去接线端711的部位接触。
具体地，隔挡件90可以隔挡板，还可以是隔挡条等，该隔挡件90将导线40固定于手柄10的内侧壁面上，由此能够使得导线40具有更好的固定效果，导线40的固定更可靠。可选地，隔挡件90靠近导线40的一侧设置卡线缺口，该的隔挡件90设置于卡线缺口内，结构更加稳定。
在本申请的一些实施例中，将隔挡件90设置为弹片，该弹片具有一定的预压力，对导线40的压持效果更好，在导线40受到牵拉时又能够产生形变，对导线40进行释放，起到固定效果的同时还具有较好的保护效果。
综上所述，本申请中的筋膜枪可以使得筋膜枪的重心朝向机身20尾端22偏移，在握持时，手腕所需弯折的角度更小，能够减轻长期握持的酸痛感，同筋膜枪的重力更多地集中在手柄10中，且重心的偏移使得重心朝向手掌偏转，握持手柄10时使得手柄10存在一定的扭转力，能够使得手掌和手指均匀受力，且筋膜枪在高频振动时，手柄10对手掌的冲击不是直接冲击手掌与按摩头30相对的一侧，通过按摩头30上扬和电机71轴线的远离手柄10的一端相对手柄10的延伸方向偏置，使得手柄10有扭转的趋势，使得手指和手掌均匀受力，有效地防止了手局部冲击大而产生的手麻问题的发生。在一些实施例中，手柄10具有其他的结构形式，具体来说，该手柄10包括呈锐角或者钝角设置的第一段和第二段(图未示出)，其中，第一段较第二段更靠近机身20并与机身20连通，电机71的至少部分位于与第一段内，且电机71的轴线方向与第一段的长度方向一致，电池130位于第二段内，电池130的轴线方向与第二段的长度方向一致。如此设置，可以使得电机71直挂，而电池130倾斜设置，从而使得电机71的轴线相对电池130的轴线偏置，可以使得筋膜枪的重心朝向机身20的前端21或者尾端22偏移，当筋膜枪的重心朝向机身20的前端21偏移，使用筋膜枪时，筋膜枪具有更好的叩击力度。当筋膜枪的重心朝向机身20的尾端22偏移，使用筋膜枪时，筋膜枪能够主动向用户的手掌压贴，可以平衡机身20的前端的转矩，握持更省力。
参见图14所示，根据本申请的实施例，还提供了一种筋膜枪，该筋膜枪包括手柄10、机身20、按摩头30以及驱动机构70。
其中，手柄10用于人手握持，机身20与手柄10连接，机身20包括前端21和与前端21相对的尾端22；按摩头30靠近前端21设置；驱动机构70包括电机71和传动组件73，电机71通过传动组件73驱动按摩头30运动，电机71至少部分位于手柄10中，传动组件73位于机身20中；其中，电机71的轴线的远离手柄10的一端相对手柄10的延伸方向朝向靠近尾端22的方向偏置，以使筋膜枪的重心朝向尾端偏移，且按摩头30的朝向远离机身20的运动方向与手柄远离机身20的延伸方向呈钝角设置。手柄10与机身20的分界线为P，需要说明的是，由于机身20与手柄10的连接部分为平滑过渡，不存在明显的分界线，只能做大致区分，该分界线P仅是为了能更清楚的理解本方案而示意的，并非绝对意义上的分界位置。
本实施例通过使电机71的轴线的远离手柄10的一端相对手柄10的延伸 方向朝向靠近尾端22的方向偏置，可以使得筋膜枪的重心朝向机身20的尾端22偏移，与此同时，且按摩头30的朝向远离机身20的运动方向与手柄向机身20的延伸方向呈钝角设置，由此，可使得按摩头30的移动轴相对手柄10的延伸方向的夹角为钝角，相当于将按摩头30上扬设置，相比于按摩头30的轴向与手柄10的延伸方向垂直设置的筋膜枪，在握持时，手腕所需弯折的角度更小，能够减轻长期握持的酸痛感。按摩头30对手柄10上的冲击与手柄10的延伸方向非正交，因此落在手掌上的冲击力与手掌非正交，存在一夹角，因此落在手掌上的力有一部分沿平行于手掌的方向分解，对于手掌的直接冲击力有效减小。电机71的偏转使得手柄10相对延伸方向的轴线朝向手掌偏转，手柄10的重力更多地集中在手掌上，手柄10具有更好的抗震的效果，有效地防止了手局部冲击大而产生的手麻问题的发生。
此外，本申请的筋膜枪的重心朝向机身20的尾端22偏移，使用筋膜枪时，筋膜枪能够主动向用户的手掌压贴，可以平衡机身20的前端的转矩，握持更省力。
手柄10内设置有电池130以用于对驱动机构70以及其他的电性元器件进行供电，该电池130的延伸方向与手柄10的延伸方向相同。
进一步地，本实施例中的驱动机构70设置于机身20中，而并非设置于机身20与手柄10交接处。具体地，驱动机构70的电机71以及传动组件73安装于机身20中，且传动组件73连接于电机71朝向电池130的一侧，此时，驱动机构70的接线端位于电机71的靠近电池130的一侧，连接电机71与电池130的导线不易与电机71发生干扰，接线更加稳定。
为了便于对电机71进行安装，只需要在机身20的背离手柄10的一侧设置凸起25，而无需将整个机身20沿机身20的轴线方向，即活塞60的轴线方向外扩，实际安装时，只需使电机71容置于该凸起25处，能够提高机身20内部空间的利用率，便于实现筋膜枪的小型化设计。
以上对本申请实施例公开的筋膜枪进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的一种筋膜枪及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本申请的限制。
