請參照圖1所示,其為本發明最簡單的一個實施例。在此一實施例,本發明包含:至少一個螺絲起子頭本體1。螺絲起子頭本體1是一支柄桿,其可與承窩扣件結合,例如:承窩螺絲及承窩螺桿,以便快速地將扭力施加於承窩扣件。螺絲起子頭本體1更包含:複數個側撐壁2、一個第一基面8、及一個第二基面9。一般而言,螺絲起子頭本體1是一個由高強度金屬所構成的球狀稜柱體。複數個側撐壁2與承窩扣件結合,以便有效地將扭力由扭力工具傳遞到承窩扣件。第一基面8及第二基面9隔著複數個側撐壁2彼此相對,且第一基面8及第二基面9垂直於複數個側撐壁2,而形成稜柱狀的螺絲起子頭本體1。 Please refer to FIG. 1, which is the simplest embodiment of the present invention. In this embodiment, the present invention includes: at least one screwdriver head body 1. The screwdriver head body 1 is a handle rod, which can be combined with a socket fastener, such as a socket screw and a socket screw, so as to quickly apply a torsion force to the socket fastener. The screwdriver head body 1 further includes: a plurality of side supporting walls 2, a first base surface 8, and a second base surface 9. Generally speaking, the screwdriver head body 1 is a spherical prism body made of high-strength metal. A plurality of side support walls 2 are combined with the socket fastener, so as to effectively transmit the torsion force from the torsion tool to the socket fastener. The first base surface 8 and the second base surface 9 are opposed to each other via a plurality of side support walls 2, and the first base surface 8 and the second base surface 9 are perpendicular to the plurality of side support walls 2 to form a prismatic screwdriver头体1。 Head body 1.

請參照圖1及圖4所示,每一個側撐壁2更包含:一個第一側緣3、一個第二側緣4、一個突出面5、一個凹入面6、及一個結合穴7。複數個側撐壁2徑向地環繞螺絲起子頭本體1的一條旋轉軸10,而產生與承窩扣件剖面互補的形狀。側撐壁2的數量隨著承窩扣件形狀改變,以便和承窩扣件的形狀互補。在本發明的一個實施例,側撐壁2的數量 是6,而產生螺絲起子頭本體1的剖面是一個六角形。在本發明的另一個實施例,側撐壁2的數量是4,而產生螺絲起子頭本體1的剖面是一個四角形。 Please refer to FIG. 1 and FIG. 4, each side support wall 2 further includes: a first side edge 3, a second side edge 4, a protruding surface 5, a concave surface 6, and a coupling cavity 7. A plurality of side support walls 2 radially surround a rotating shaft 10 of the screwdriver head body 1 to produce a shape complementary to the cross-section of the socket fastener. The number of side support walls 2 changes with the shape of the socket fastener so as to be complementary to the shape of the socket fastener. In one embodiment of the present invention, the number of side stay walls 2 is 6, and the cross-section of the body 1 of the screwdriver head is a hexagon. In another embodiment of the present invention, the number of side support walls 2 is 4, and the cross section of the body 1 of the screwdriver head is a quadrangle.

突出面5及凹入面6形成一個支撐面。支撐面頂靠著承窩扣件,尤其是承窩扣件頭部的側壁。突出面5及凹入面6形成的支撐面是一個曲面,如此複數個側撐壁2可以形成一個球形。突出面5鄰近第一基面8,而且複數個側撐壁2的複數個突出面5形成為球形的本體。凹入面6鄰近突出面5並相對於第一基面8;複數個側撐壁2的複數個凹入面6也參與球形的產生。複數個凹入面6也提供餘裕空隙讓螺絲起子頭本體1以一個角度結合於承窩扣件。突出面5及凹入面6沿著螺絲起子頭本體1的旋轉軸10分佈,使球形位於螺絲起子頭本體1的終端。在本發明的一個較佳實施例,突出面5及凹入面6的曲率、長度、及高度都相同。第一側緣3及第二側緣4隔著突出面5及凹入面6,也就是支撐面,彼此相對。從上視圖或下視圖來看,複數個側撐壁2的第一側緣3和第二側緣4構成螺絲起子頭本體1的稜角。結合穴7形成額外的夾持齒,用與承窩扣件側壁結合。結合穴7垂直地深入突出面5及凹入面6。結合穴7從螺絲起子頭本體1的第一基面8出發到達第二基面9,以沿著球形形成額外的夾持齒。不管螺絲起子頭本體1與承窩扣件之間的角度如何,此些額外的夾持齒總是能夠與承窩扣件結合。 The protruding surface 5 and the concave surface 6 form a supporting surface. The supporting surface rests against the socket fastener, especially the side wall of the head of the socket fastener.

The concave surface 6 is adjacent to the protruding surface 5 and opposite to the first base surface 8; the plurality of concave surfaces 6 of the plurality of side support walls 2 also participate in the generation of the spherical shape. The plurality of concave surfaces 6 also provide a margin for the screwdriver head body 1 to be combined with the socket fastener at an angle. The protruding surface 5 and the concave surface 6 are distributed along the rotation axis 10 of the screwdriver head body 1 so that the spherical shape is located at the terminal end of the screwdriver head body 1. In a preferred embodiment of the present invention, the curvature, length, and height of the protruding surface 5 and the concave surface 6 are the same.

From the top view or the bottom view, the first side edge 3 and the second side edge 4 of the plurality of side support walls 2 constitute the edges and corners of the screwdriver head body 1. The coupling cavity 7 forms additional clamping teeth for coupling with the side wall of the socket fastener. The coupling hole 7 penetrates into the protruding surface 5 and the concave surface 6 vertically. The coupling cavity 7 starts from the first base surface 8 of the screwdriver head body 1 and reaches the second base surface 9 to form additional clamping teeth along the spherical shape. Regardless of the angle between the screwdriver head body 1 and the socket fastener, these additional clamping teeth can always be combined with the socket fastener.

請參照圖4及圖5。每一個側撐壁2的額外的夾持點都是由結合穴7及鄰近的側緣,也就是第一側緣3,所產生。結合穴7及第一側緣3的距離決定額外夾持齒的夾持點,並且隨著扣件的尺寸及設計而調 整。在一實施例,結合穴7自第一基面8朝著第二基面9逐漸變細,以減少銳利邊緣的數量,從而防止使用者不小心按壓到並且割傷。在一個較佳的實施例,結合穴7具有一個三角形的剖面。三角形的剖面確保額外夾持齒夠銳利,並且不會減少螺絲起子頭本體1整體結構的完整性。在本發明的其他實施例,結合穴7可具有其他形狀的剖面。其他形狀的剖面包括但不限於是:半正方形、半長方形、及半橢圓形的剖面。 Please refer to Figure 4 and Figure 5. The additional clamping point of each side support wall 2 is generated by the coupling cavity 7 and the adjacent side edge, that is, the first side edge 3. The distance between the coupling cavity 7 and the first side edge 3 determines the clamping point of the additional clamping teeth, and is adjusted according to the size and design of the fastener. In one embodiment, the bonding cavity 7 is tapered from the first base surface 8 toward the second base surface 9 to reduce the number of sharp edges, thereby preventing the user from accidentally pressing and cutting. In a preferred embodiment, the coupling cavity 7 has a triangular cross-section. The triangular cross-section ensures that the additional clamping teeth are sharp enough and does not reduce the overall structural integrity of the screwdriver head body 1. In other embodiments of the present invention, the coupling cavity 7 may have a cross-section with other shapes. Other shapes of cross-sections include but are not limited to: half-square, half-rectangular, and half-elliptical cross-sections.
