  • Both the pen-hold and the horizontal shot have their own advantages, and each has its own insurmountable disadvantages. This is mainly due to the handle grip structure.
  • the pen-holding is concentrated on the longitudinal center axis of the hitting area of the racket due to the control angle and the strength of the fingers.
  • the two sides make the pen-holding with great flexibility, feel and quick small-angle face change, but the large-angle front pressure angle of the forward and reverse hands of the pen-hold can not reach the physiological curvature, and it is operated by twisting the wrist. Difficult to train, it is difficult to exercise, and its uncomfortable factors also affect the fun of sports.
  • the strength of the finger grip is small, especially the backhand strength is very small.
  • the grip of the horizontal grip is that the palm of the hand grips the grip, the power is great, and the hitting is powerful, but in the forehand and backhand or the ball, in order to pull out the high-quality rotating ball or close to the countertop
  • the ball needs to be sunk to the head to do it. This is because the horizontal shot of the racket hits the sweet spot above the arm axis and the vertical distance from the arm axis is relatively far away. The strength of the whipping type of force is strong. Secondly, only the sweet spot of the shot is below the axis of the arm, which is the most favorable position for hitting the ball close to the table.
  • the wrist In the wrist case, the wrist is tight and inflexible, which in turn affects the flexibility and change of the angle of the forward forehand, the angle of the attack, the control of the finger is not flexible, the control of the ball is poor, and the front end of the index finger is far from the sweet spot of the shot.
  • the hand is not clear.

Sink down the head so that the center of the hitting area is on the axis of the arm. This additional action will not only cause slow reaction time, but also the tension of the wrist ligament will affect the axial rotation and back and forth swing of the wrist, and then the racket control.
  • the content of the invention In order to overcome the problem that the existing straight plate grip structure leads to the influence of the physiological curvature limitation technology in use, the beginners master the difficulty of the table tennis exercise and raise the threshold height, and the improvement of the compliance curve of the table tennis bottom plate.

直拍和横拍各有优点， 也各有不能克服的缺点， 这主要是由于柄部握拍 结构导致， 直拍由于控制角度和力量的手指都集中在球拍的击球区纵向中轴 线对称的两侧使得直拍具有很好的灵活性、 手感和快捷的小角度拍面变化， 但是直拍的正反手位的大角度前压拍角生理曲度达不到， 以扭曲手腕的方式 操作难度大训练难度大， 其不舒适的因素也影响运动的乐趣， 再加上手指握 拍力量小， 特别是反手力量很小， 这也需要大量的训练增强手指力量后才能 熟练使用， 并且对手指也有一定得伤害， 还有其自然握拍时球拍击球区中心 在小臂轴线的下方， 并且距轴线垂直距离很远， 这大大影响了鞭打式的发力 的力传递效率， 也是直拍虽然在小动作攻击上快速便捷， 但是在大动作发力 的绝对力量上小于横怕的主要原因， 也就形成了近台强中远台弱势的特点， 就趋势来看， 选择直拍的新人越来越少， 还是因为直拍的整体技术实力上升 空间受限， 总结下主要是几个缺点： 正反手大角度压拍扭曲生理曲度造成的 困难、 手指握拍的方式导致力量小以及球拍击球区在自然握拍时距离小臂轴 线太远导致的发大力时力量小， 中远台实力差。
横握拍的握法是手掌攥住握拍， 力量很大， 击球有力， 但是无论是在正 手和反手拉球或者击球时， 为了能拉出高质量的旋转球或者对贴近台面的球 进行处理都需要把拍头下沉才能做到， 这是因为横拍在自然握拍时球拍击球 甜区处在小臂轴线的上方且距离小臂轴线垂直距离比较远， 首先这影响了大 力量发力的鞭打式的发力效率， 其次只有击球甜区在小臂轴线下方才是最有 利于击打贴近台面的小球的位置， 吊腕虽然可以解决这两个问题， 但是造成 的手腕韧带紧绷将导致手腕僵硬， 影响手腕的发力和灵活性， 这也是为什么 横拍小球控制和快攻差于直拍的原因， 但是相对于直拍来讲横拍的缺点可以 通过大量的训练让选手在一定程度上适应吊腕带来的不便， 所以我们看职业 选手比赛时他们的球拍多是下沉到击球甜区和小臂轴线处在一条直线上， 但 是即使如此这种违反人体生理曲度的动作带来的不便无法消除并且也一直影 响着技术发挥。 在业余选手中吊腕现象相对就少很多， 还是因为这种方式很 不舒服并且需要大量训练才能适应， 手腕韧带处于紧张状态时攻球角度受到 限制， 击球瞬间的控球变化受到限制， 食指处在距离球拍击球甜区很远的位 置导致手感不好， 总结下缺点是： 横拍的吊腕对手腕的韧带的紧张拉伸使得 吊腕情况下手腕紧绷不灵活， 进而影响到特别是正手大幅度前倾压拍、 攻击 时角度的灵活性和变化， 微小控制手指不灵活， 小球控制差， 食指前端距离 击球甜区远的手感不清晰。
很长时间来， 人们对于直握横握拍的问题也是深感困惑， 于是有很多创 新出现， 其中最为引人注目是一类对在自然握拍时击球区中心相对于小臂轴 线位置方面的球拍握柄结构改进， 这种改进的目的很明显的是为了解决自然 握拍状态下拍面击球甜区在小小臂轴线下方的直拍和在小臂轴线上方的横拍 所遇到的为了调整到小臂轴线上而扭曲手腕生理曲度的问题， 例如：
Z1200420047683.8, zl98205697.4和 zl99228224.1等很多类似的创新 ， 都把 击球甜区的位置调整到接近或者比较接近小臂轴线的位置， 但是这些创新在 实用中却无法得到很好的应用， 其原因有三点， 首先， 虽然直拍和横拍都有 自身的缺点， 但是基本都能做到使用上没有不能通过训练缓解的过份违反发 力原理的缺陷， 可很多这种改进握柄的发明， 由于拇指和食指捏住的位置偏 离球拍击球区纵向纵轴线太远， 导致拍在手中转动的轴线和球拍击球区纵向 中轴线偏离太大， 控制球难度大、 变化的灵活性差、 球拍倾角度的变化困难 以及力量的传递不能集中， 小球控制差， 这些都是违反了一个控制和发力的 基本结构原理， 既是球拍主要的纵向施力轴、 调整拍前倾角度的纵向旋转控 制轴以及球拍击球区纵向中轴线要从合一线的原则， 这些问题导致其在使用 中无法通过训练弥补， 过多的失误， 发力不适， 变化的威胁小等等让使用者 没有信心使用； 其次， 握拍位置太靠上、 太靠后或者食指翘的太高处于球拍 纵向中轴线上方了， 食指尖端不能对球拍拍面纵向中轴线下部的位置有很好 的控制， 而这部分是控制小球、 搓球和弧圈球的微小变换控制的主要区域， 太靠后也导致手指距离击球甜区中心过远， 手感和控制都不好， 失误很多； 第三， 球拍击球区纵向中轴线两侧质量不平衡， 导致球拍的重心大大偏离球 拍击球区纵向中轴线， 鞭打式甩动发力和微小控制时球拍拍形容易走偏， 力 量不能集中在中线上； 还有， 虎口部分不能卡住， 给这种握法造成稳定性不 足； 还有部分创新设计球拍击球部分和拍柄的衔接部分太窄导致球拍球板发 颤； 球拍击球拍面某些位置上没有得到柄部的足够支撑导致的击球时部分拍 板颤动太大控制失准； 握柄太大太粗， 手握时无法微调导致控制不灵活； 以 及设置很多单个的指孔让手指插入导致握时卡的太死， 微小调整拍面角度不 方便控制不好等等， 这些使得这些设计在使用中失误很多又很难通过训练克 服， 而最终无法推广普及。
乒乓球拍由网球演变而来， 拍头减小， 拍柄变短， 网状面变成胶皮面， 这都是为了适应乒乓球运动的特点， 是为了更好的击打控制， 但是目前我们 仍然面临很大的器材使用中的障碍，玩过多种竞技球类运动的的人都有体会, 乒乓球的入门相对要难， 要是玩球的双方能把球打起多个回合不失误， 业余 情况下至少要练习半年到一年以上， 而羽毛球或者其他一些球类， 只需进行 一周甚至几天的熟悉就可以对阵， 这一方面源于目前使用的材料还不够先进 之外一个重要的原因是目前我们使用的直拍和横拍的握柄使用是扭曲人体正 常生理曲度的非自然舒适的动作， 要控制好发力好就需要做大量的适应性训 练， 这些训练中很多是为了去适应这种非自然生理曲度的动作，从直拍看来, 食指拇指对称的钳握在拍的中轴线两侧， 施力轴及倾角旋转轴和中线重合， 所以力量集中， 控制也很好， 但也是由于这种卡在手指缝中的握拍的方式导 致在正手大角度和反手大角度前倾压拍时手腕自然角度不能到位， 手腕必须 做扭曲生理曲度的大角度调整才能达到压拍角度， 技术实施比较别扭， 反手 位即便是出现直拍横打的新技术后， 这种由几个指头握拍的方式仍然没有改 变其力量小和反手攻球角度受限的根本缺点， 而且直拍横打的训练和使用难 度高也影响到专业余选手的技术发挥； 横拍自然握拍时拍面在小臂轴线的上 方， 整个手掌握住拍柄， 施力轴及倾角旋转轴和中线重合， 握力足， 力矩长, 力量大， 但是由于， 最灵活的控制手指食指和拇指相对击球甜区的位远， 食 指尖部和拇指尖部相对球拍击球区的纵向中轴线距离也远， 对球拍的角度变 化控制相对不灵活， 手对拍的震动感知也不够细膩， 最为关键的是拍面在小 臂轴线上方， 迎击球时腕部挥动行程余地小， 小臂到球拍头部的力量传递走 了 L路线， 往往为了实现很顺畅的发力和击打都要把拍头沉下来， 使得击球 区中心在小臂轴线上， 这种附加动作不但会导致反应时间慢， 手腕部韧带的 紧张拉长也影响腕部的轴向旋转和前后摆动， 进而球拍控制的精确性和攻击 角度受限， 不好掌握； 以上这些直握拍和横握拍的使用困难多是通过大量的 适应性训练克服， 无形中延长了掌握的难度和增加娱乐投入成本， 对于乒乓 球有着高度专业化的中国正因为有着强大的训练体系容易导致我们忽略了其 运动深入普及和提髙存在着相当的难度， 其实这对于业余爱好者就是一个进 入和提高的门槛， 这也是乒乓球运动为什么相对其他运动更难上手的原因之 一， 更是在国外没有强大的国家传统体系支持下民间乒乓技术难以提高和强 大的原因之一。
3、 发明内容 为了克服现有直板横板握柄结构导致使用时生理曲度受限影响技术发挥 的问题， 初学者掌握乒乓球运动难度大水平提高门槛高的问题， 以及乒乓球 底板的顺应生理曲度的改进 把球拍击球甜区中心调整到自然握拍时接近 小臂轴线的位置， 并仍能保持良好的发力、 控制和变化的问题， 本发明提供 一种自然握拍时球拍击球甜区中心接近小臂轴线， 能实现吻合人体自然生理 曲度的自然握拍、 舒适的发力和自如控制的前提下还能有强于现有普遍使用 的球拍的小球控制、 攻球角度变化、 力量水平和技术的全面性等一些特长和 整体实力， 并且使用简便， 相对以往球拍结构不需要太多适应性训练的容易 被初学者学会掌握的柄部改进的乒乓球底板。
本发明是通过如下技术方案来实现的：
包括击球板、 球拍握柄、 指孔以及凸块组成， 指孔位于握柄的前方， 凸 块位于握柄的上方， 其特征在于： 凸块和握柄形成凹槽的顶点同指孔距离中 轴线的最近点指孔顶点相对位于球拍击球区的纵向中轴线两侧， 凹槽的顶点 位于球拍击球区的纵向中轴线向上一侧 0到 3.3厘米之间， 指孔顶点位于中 轴线向下一侧 0到 2.5厘米之间,指孔能同时穿过三个手指。 握拍方法是， 虎 口贴近凹槽顶点， 中指、 无名指和小指穿过指孔握住拍柄， 拇指和食指夹住 拍面， 这种握柄的结构使得手在抓握时， 食指根部和拇指也可以自然的贴合 在击球区纵向中轴线上， 自然的夹住球拍纵向中轴线的拍面， 对球拍拍面倾 角、 攻球角度和瞬间变化有良好控制和手感， 再加上凹槽顶点和指孔顶点相 对纵向中线的距离限制就使得球拍击球区处在小臂轴线附近， 这有利分别于 力量的传递和突击， 另外这种距离的限制也使得握拍时食指尖部处在球拍中 轴线的下方不远处， 只有这个位置食指才可以配合其他手指对整个球拍起到 均衡控制的效果， 中指、 无名指和小指穿过指孔握住握柄， 给球拍以更大的 力量支持， 力量上不次于横握拍， 对比直握拍和横握拍来讲， 球拍的击球区 中心位于小臂轴线附近， 并和手掌处于几乎同一平面， 这也使得手对拍面位 置、 角度、 振动和变化的感知都比较清晰， 正反手前倾压拍和攻球角度的变 化就像调整手掌一样便捷； 手腕可旋角度大了很多， 能在生理曲度范围内就 可以满足几乎所有常规技术的需要， 不会像横拍的吊腕使手腕紧绷， 也不会 像直握拍正反手大角度前倾拍面那样困难， 整个手掌握住拍柄力量上要大于 直握拍； 在小球控制上， 由于食指和拇指紧密夹住在球拍击球区的纵向中轴 线位置的拍面， 食指更接近球拍击球甜区，手指对击球甜区控制和感知清晰, 导致小力量的小球控制很好， 这点相比食指远离球球拍击球甜区的横握拍在 小球控制上有明显优势， 总体来说自然的抓握和顺应人体自然生理曲度的动 作比现有直拍和横拍更符合人体生理结构， 既有比较好的发力和小球控制， 也做到了技术全面没有明显漏洞， 由于容易稳固拍形， 初学者相对花更少的 时间去做适应训练， 使用起来也相对舒适， 提高了对乒乓运动的兴趣； 更为 关键的是使用本发明结构握柄时控制拍的关键手指一一拇指和食指刚好贴合 在球拍击球区的纵向中轴线上， 使得控制球拍倾角的旋转轴、 球拍施力轴以 及球拍纵向中线处在同一线上， 这点解决了以往对握柄改进的一些发明的问 题， 实现了良好的控制和自然的发力， 食指的指尖伸向前下方并贴合在球拍 击球区纵向中轴线下方不远处， 这一点对小球处理的主要拍面区域一一球拍 纵向中轴线下方的区域手感控制很好， 并且只有这个位置才能兼顾对球拍纵 向中轴线上方和下方区域的控制， 因为我们在小球控制中， 主要要求控制的 是球拍的纵向中轴线下方的区域， 弧圈球和攻球时的主要击打触球点是球拍 纵向中轴线上部的位置， 但所有细小的控制和瞬间的机动变化多在中轴线下 部这个位置完成， 归根结底控制好球拍纵向中轴线的下部就是取得了控制的 关键， 这也是此类创新发明设计上的重要一环， 本发明使得食指对球拍击球 区纵向中轴线两侧部位的手感和控制比较均衡， 食指指尖自然处于球拍纵向 中轴线下方不远处， 正手攻球时手指还可以微调至球拍纵向中轴线上， 获得 更有力的攻球击球， 整体上对击球的感知和控制都优于以往对握柄改进的类 似发明； 以上这些改进都实现了既有符合人体生理曲度的先进性又不脱离实 际使用效果的结构改进。
上述方案还可以通过以下措施做进一歩的改进：
握柄是扁平的且垂直距离靠近中轴线的一端宽度窄于另一端。 对于握柄 形状的限制使得握柄符合手掌抓握的生理结构， 保证了手抓握球拍时兼有明 显的拍面纵向仰角和拍面横向仰角的感知， 有利于弧圈和快攻技术的实施， 再加上握柄较宽对拍面横向的控制力度大有利于击打式的攻球时提高稳定 性， 以及对球拍倾角的手指调整也比较清晰方便， 这种结构完全适合手掌的 形状使得贴合自然， 稍稍用力就可以握紧稍稍放松就可以灵活， 增强控制减 少适应难度。
凸块的下边沿为弧形， 由凹槽的顶点到凸块下边沿末端的弦长度在 2.5 厘米到 7厘米之间。其中最佳时在 3.5厘米到 5.5厘米之间， 弧形设计可以更 好的贴合虎口的生理形状有利益更稳固的握拍， 对凸块的尺寸限制使得整个 拍的中轴线两侧的质量得以平衡， 球拍重心处在球拍纵向中轴线上， 这在控 制球拍时不会造成拍型走偏有利于控制和发力集中，
凹槽顶点同击球板前端尖部的距离在 16厘米到 18.5厘米之间。 长度的 限制使得球拍保证有良好的控制的前提下也能有良好的威力。
指孔顶点位于中轴线向下一侧 1到 2厘米之间。 这限定了中指和食指的 位置， 能使得食指和中指很好的控制住拍面中轴线下部的区域同时也可以兼 顾了上部的区域， 因为如果食指尖贴合在中轴线上部则无法兼顾对下部区域 的控制。
握柄最窄处宽度在 3厘米到 4.5厘米之间。 这个尺寸限定了握柄根部尺 寸， 使得在击球时既有足够的扭矩用来发力也不至于过宽抓握影响灵活性。
握柄最宽处宽度在 3.5厘米到 6.5厘米之间。这个尺寸限定了握柄末端尺 寸， 符合人手抓握时掌底宽大的形状， 对于球拍的控制拍面倾角的感知以及 发力的支持和拍面的稳固都很有利。
指孔上部握柄一侧设有能卡住食指的梁。 抓握时， 中指卡住梁， 梁的设 置大大加强了食指和中指对球拍中轴线下部的控制， 使得在小球特别是正手 小球控制和正手台内球突击时击球更加稳健。
当握柄的后沿同中轴线的夹角在 0度到 15度之间时，凹槽顶点位于中轴 线向上一侧 2.3厘米到 3.3厘米之间，指孔顶点位于中轴线向下一侧 1厘米到 1.8厘米之间。 这个尺寸结构使得自然握拍时球拍击球区刚好在小臂轴线上， 发力顺畅， 有力量大和护台宽的突出特点， 适合实施弧圈结合快攻的实力派 技战术实施。
当握柄的后沿同中轴线的夹角在 44度到 54度之间时， 凹槽顶点位于中 轴线向上一侧 0到 0.6厘米之间，指孔顶点位于中轴线向下一侧 1.3厘米到 1.9 厘米之间。 这个尺寸结构使得自然握拍时球拍击球区刚好在小臂轴线下方， 和小臂轴线有一段垂直距离， 但是这个距离小于直握拍和小臂轴线的这个距 离， 握拍时食指尖部接近球拍纵向中轴线， 这种结构导致手指对击球区的手 感很好， 对小球控制也很好， 有利实施快速击打， 拍头在小臂轴线下上手也 快， 并可以正反手快攻上手， 虽然大动作甩动发力时能量损失相对后沿同中 轴线的夹角在 0度到 15度之间时大些， 中远台弧圈力量小些， 但是非常适合 较小动作的快速攻击， 比如快攻、 近台快节奏和快拉弧圈的结合， 适合以快 攻为主的技战术实施。
本发明和现有技术相比有如下优点： 本发明的结构使得球拍击球区在小 臂轴线上或非常接近， 食指根部和拇指都捏住球拍击球区的纵向中轴线， 食 指尖端处于球拍纵向中轴线下方附近， 且距离击球甜区很近， 中指、 无名指 和小指都能在自然轻松的状态下稳固的握住拍柄， 这结构使得： 相对于目前 在普遍使用的直握拍和横握拍， 其自然握拍情况下拍的击球甜区更接近小臂 轴线， 发力时力量传递效率高， 发力流畅自然容易控制， 正反手都不用采用 吊腕等手段调整球拍和小臂轴线的位置就可以发出很大的力量； 且由于手腕 转动不受限制， 可旋角度大， 无论正手反手还是中路， 对于拍前倾角度的调 节以及攻击角度的调节都能像使用手掌一样靠手腕在自然的生理曲度范围内 轻松做到， 这点是直拍和横拍所不具备的； 在自然握拍下拍面所处的位置在 小臂轴线上或者下部很近处， 这几乎是攻击启动的最佳位置， 不用像横握拍 那样调整拍和手臂的位置， 这样动作行程小了很多， 上手速度快； 食指和拇 指夹住球拍纵向中轴， 食指尖部很接近球拍击球甜区， 这导致手指对球拍的 感知、 控制、 倾角变化震动变化等更加清晰， 使得小球的处理上大大优于横 板很接近直板； 食指伸向前方处于中轴线下方不远处， 使手指对于中轴线两 侧的拍面达到全面控制； 整体上， 无论上旋、 下旋、 弧圈还是攻球、 小球处 理等都没有技术上的明显漏洞， 因为握拍和击球区位置更符合人体的生理特 点， 球拍如同手掌的延长， 使用起来也感觉很自如， 相对以往球拍结构可以 用更少的时间就能掌握， 发力也有力， 动作自如隐蔽变化多， 很容易上手； 相对于以往对握拍位置的改进的发明， 食指和拇指握拍时夹住了球拍击球区 纵向中轴线， 球拍的倾角的调节旋转轴在中轴线上， 力量的施力轴也同纵向 中轴线重合， 它不违反发力的施力轴和倾角的旋转轴不能过分偏离球拍击球 区纵向中轴线的原则， 控制好， 手感好， 力量传递效率高， 由于本发明设有 握柄上部设有平衡质量的凸块，球拍击球区纵向中轴线两侧的质量基本平衡, 球拍的重心不偏离球拍击球区纵向中轴线， 凸块下边沿贴合住虎口使得握拍 更加稳健， 改变以往此类方向上发明握拍不稳方向感不好的问题， 且主要控 制球拍的手指食指尖部距离击球甜区距离近， 对于球拍的手感控制都很好， 因为食指前端位于球拍纵向中轴线下方不远处， 只有这个位置才能够全面均 衡的对球拍击球区的纵向中轴线两侧的击球区域都有有良好的控制， 不至于 导致控制上的盲区； 对于初学者来说， 握拍自然接近手掌的延长， 方向感挥 动感角度感知都很清晰， 手指更贴近球拍击球甜区， 手感很清晰， 握拍也更 加稳固， 拍角度控制起来就相对容易很多， 击球时拍面角度也不易失控， 也 没有诸如吊腕等扭曲手腕的规范要求， 击球启动自然迅速， 特点突出， 没有 明显漏洞， 减少失误， 增加了乒乓运动的兴趣， 有利于爱好者选择和更广泛 的普及； 另外， 其改进中没有复杂的结构， 同现有产品的生产成本和工艺没 有明显的变化， 开展新产品的生产转换成本小， 对于拍板的配套设施、胶皮、 包装等也可以沿用， 无需单独调整， 最大限度的降低了使用转换成本。

下面结合附图对本发明做进一步说明
本发明实施例一如图 1和图 2所示， 包括击球板 1和球拍握柄 2,指孔 3 以及凸块 6组成， 指孔 3位于握柄 2的前方， 凸块 6位于握柄 2的上方， 其 中 4是握柄 2的后边沿， 5是凸块 6的下边沿， 7是球拍击球区的纵向中轴线, 8是握柄 2和凸块 6所形成的凹槽的顶点， 9是指孔 3的上方最接近中轴线 7 的顶点， 在此结构中， 指孔 3能同时穿过三个手指， 凸块 6的下边沿 5为弧 形， 其弦长度在 3厘米到 5厘米之间， 最佳是在 3.7厘米， 这使得凸块具有 平衡球拍击球区纵向中线 7两侧的质量的作用， 使得球拍重心在中线 7上， 凸块还有卡住虎口稳固拍形的作用， 凸块 6后上方可以做成弧形， 避免挥动 时碰到头部； 凹槽顶点 8同击球板 1尖部的距离在 16厘米到 18.5厘米之间， 这个尺寸限定使得球拍既能很好的控制又有一定的威力； 凹槽顶点 8位于中 轴线 Ί向上一侧 2.3厘米到 3.3厘米之间， 最佳是 2.7厘米， 指孔顶点 9位于 中轴线 7向下一侧 1厘米到 1.8厘米之间， 最佳是 1.3厘米， 使得握拍时拇指 食指刚好捏住球拍中线 7， 无论是控制、 球感、 发力还是调整球拍倾角都好 掌握； 握柄 2最窄处宽度在 3厘米到 4.5厘米之间， 最佳是在 3.3厘米， 握柄 2最宽处宽度在 3.5厘米到 6.5厘米之间， 最佳是在 5厘米， 这使得球拍既有 可在手中转动的灵活性也有足有的力矩稳固拍形； 握柄 2的后沿 4同中轴线 7的夹角在 4度到 15度， 最佳是在 10度， 这使得自然握拍时球拍击球区纵 向中轴线 7刚好好小臂轴线重合， 力量传递效率达到最佳， 适合大力量两面 弧圈型技术打法的实施； 指孔 3上部靠近握柄一侧设有能卡住食指的梁 10， 这个梁 10能使得握拍时中指对球拍纵向中线 7下部的区域有更稳固的控制， 同时也不会影响灵活性； 总体来说实施例一手指接近甜区， 球感、 控制和发 力都更好， 击球区在小臂轴线上， 大力量的力量传递效率高， 力量传递快， 击球启动也比横拍更快， 相对横拍不需要沉腕， 手腕自然舒适不紧绷， 可旋 角度大， 转动自如灵活， 进攻线路更加宽泛和变化更多， 也导致出球线路不 易被判断威胁大， 特别是正手解决了横拍正手线路由于生理结构原因非常狭 窄容易被对方判断必须通过大量的训练才能弥补的缺点，球拍的纵向施力轴、 调节倾角的旋转轴以及球拍纵向中轴线 7三线重合， 符合发力和控制原理， 更加适合两面弧圈综合实力打法的技术实施无论是在小球控制还是在发力上 以及出球威胁上都好于横拍， 解决了横拍一直来困扰的问题， 更能把两面弧 圈的综合实力的打法发扬光大。 也比现有的对球拍击球区改进到小臂轴线上 的革新发明更加实用没有明显的控制障碍。
本发明实施例二如图 3和图 4所示， 和实施例一的区别是， 握柄 2的后 沿 4同中轴线 7的夹角是 0度， 使得球拍纵向力轴更长且为直线， 击打更加 有力， 除了具有实施例一的优势外， 实施例二更加适合实施快攻结合弧圈、 综合实力强、 技术全面的速度加力量型技战术打法。
本发明实施例三如图 5和图 6所示： 和实施例一的区别是， 当握柄 2的 后沿 4同中轴线 7的夹角在 44度到 54度之间时， 最佳是在 47度， 这个角度 使得握拍时， 球拍甜区中心点位于小臂轴线下方很近处； 凹槽顶点 8位于中 轴线 7向上一侧 0厘米到 0.6厘米之间， 最佳是 0.3厘米，指孔顶点 9位于中 轴线 7向下一侧 1.3厘米到 1.9厘米之间， 最佳是 1.6厘米， 这使得握拍时食 指拇指刚好捏住球拍纵向中线 7握柄 2最窄处宽度最佳是在 3厘米到 4厘米 之间， 当处于 3.3厘米时最舒适， 握柄 2最宽处宽度最佳是在 3.5厘米到 6.5 厘米之间， 最佳是 5.5厘米， 这使得既有球拍可在手中转动的灵活性也有一 定的稳固性； 指孔 3上部靠近握柄 2—侧设有能卡住食指的梁 10， 这使得中 指卡住梁 10， 对球拍纵向中线 7下方的拍面区域有良好的控制； 凸块 6的下 边沿 5为弧形， 在需要时卡住虎口稳固拍形的做用， 由凹槽的顶点 8到末端 的弦长度在 2.5厘米到 7厘米之间最佳是在 5厘米， 这使得凸块有一定的重 量能平衡中线 7两侧的球拍质量， 使得重心处在中线 7上， 凸块 6后上方可 以做成弧形， 避免挥动时碰到头部。 以上尺寸结构使得自然握拍时球拍击球 区中心刚好在小臂轴线下方， 和小臂轴线有一段垂直距离， 但是这个距离小 于直握拍和小臂轴线的这个距离，球拍纵向中线 7和小臂轴线夹角接近 20到 30度， 这使得在力量效率上虽然稍逊与实施例一和二但攻击的出球线路更加 变化多端， 难以被对方判断， 握拍时食指尖部比实施例一更接近球拍纵向中 轴线， 对球拍纵向中线 7两侧的区域都有良好的感知和控制， 食指拇指捏住 球拍纵向中线 7， 加上食指尖很靠近甜区， 这导致手感很好， 小球控制好， 力量传递也快， 上手快， 旋转球拍倾角迅速快捷， 由于手腕不受限制， 灵活 可旋角度大， 所以出球线路模糊， 威胁大， 甜区的位置比直拍更接近小臂轴 线， 所以发力上大于直拍， 正反手都能攻防， 技术全面性上优于直拍， 还由 于其拍头在小臂轴线下方， 导致对于， 台内球的处理和攻击优于横拍， 适合 以快攻为主结合弧圈的特长突出的技战术打法，指孔 3的梁 10的设置增加了 球拍向斜下方的握力矩，中指握住梁 10可以使得对球拍中线下部的区域的控 制非常稳健， 有利于正反手快攻和小球的控制。 总结是， 实施例三具有直拍 的快速启动突击快攻的优势， 在小球控制上接近直拍优于横拍， 又具有横拍 的两面攻守的全面性， 没有明显漏洞， 可以继承中国传统的纯快攻或者快攻 结合弧圈的打法同时又避免了原打法中使用直拍导致的反手漏洞， 有利于快 攻技术的发展。
本发明实施例四如图 7和图 8所示： 和实施例一的区别是， 当握柄 2的 后沿 4同中轴线 7的夹角在 20度到 35度之间时， 最佳是在 24度， 凹槽顶点 8位于中轴线 7向上一侧 1厘米到 2厘米之间， 最佳是在 1.5厘米， 指孔顶点 9位于中轴线 7向下一侧 1.5厘米到 2.5厘米之间， 最佳是在 2厘米。 握柄 2 最窄处宽度最佳是在 3厘米到 4厘米之间。 握柄 2最宽处宽度最佳是在 4.5 厘米到 5.5厘米之间， 凸块 6后上方可以做成弧形， 避免挥动时碰到头部。 抓握实施例四时， 虎口更靠球拍上部， 前压拍型更加容易， 这也造成相对实 施例三更容易制造弧圈， 而且其球拍击球区在小臂轴线下部， 对于处理小球 和快速突击很有利， 另外食指拇指夹住球拍纵向中线处拍面， 有良好的施力 和控制， 食指尖距离球拍纵向中轴线很近， 总之实施例四是结合了实施例一 合实施例三的特点， 既有快速上手，和角度灵活的特点也有制造旋转的实力， 力量大于实施例三， 灵活性大于实施例一， 适合实施以快速弧圈为主的变化 型的技战术打法。
