Description of the invention: (1) Technical field of the invention The present invention relates to a handle for a socket wrench, inclusively for driving the sleeve, an adapter (cap is installed on the handle body composed of a rod body) ) The handle of the socket wrench (combined with the socket to form the socket wrench). (II) The prior art has a structure in which the adapter (cap) is formed on a handle body formed by a rod body having steel balls for preventing falling off from being mounted on both ends of the handle body, and The main body is slidably inserted into an assembly hole (through hole) provided in the adapter, and a sleeve and an extension rod are combined into an insert body provided in the adapter (for example, Patent Document i). Patent Document 1: Japanese Utility Model Laid-Open Publication No. 6-9876. In the above-mentioned prior art, the cross-section of the rod body constituting the handle body is formed in a circular shape. Therefore, the shape of the mounting hole on the adapter side to which the handle body is fitted is also circular. Therefore, when driving the sleeve (fitting nut, bolt head), there may be cases where the driving force given from the handle body side cannot be transmitted to the sleeve side through the adapter, because the handle body is relatively Small changes, such as the tilt of the subject, cause rotation. (3) Summary of the Invention The object of the present invention is to provide a handle for a socket wrench with an adapter, which can prevent a reduction in driving force due to the engagement relationship between the handle body and the adapter as much as possible. The structure of the present invention is such that the adapter body is formed in the following manner on a handle body formed by a rod body with steel balls for preventing falling off being attached to both ends of the handle body, and the handle body is slidably inserted into the handle body. In the mounting hole provided in the adapter, the cross-sectional shape of the handle body and the shape of the mounting hole are oval shapes that are consistent with each other. It is needless to say that the ellipse mentioned here does not strictly refer to the trajectory of the point where the distance from the two fulcrum points is fixed. In addition, a fixing ball protruding into the mounting hole by the action of a spring is accommodated in the adapter, and a blocking hole coupled to or separated from the fixing ball is provided at a longitudinal middle position of the handle body, and the structure is added to the above According to the solution, a so-called T-shaped handle can be obtained by using two-handed operation to reliably give a driving force to the sleeve. According to the present invention, the adapter can be rotated around the handle body's peripheral side without centering on the handle body. Therefore, the turning force given from the handle body to the adapter can be transmitted to the sleeve as a driving force, and the driving operation (tightening of a nut, etc.) is provided. Operation, loosening operation, etc.) Efficient handle for socket wrenches. (4) Embodiment The drawing shows an embodiment related to the handle for a socket wrench according to the present invention. The handle for the socket wrench in the embodiment is formed by assembling the handle body 1 and the adapter (cap) 2 with each other. The handle body 1 is composed of a metal straight rod-shaped rod body with an oval cross-section. 1 is inserted into the mounting hole 3 of the adapter 2 to form a handle A for a socket wrench, and the adapter 2 is provided with a mounting hole 3 consistent with a cross-sectional shape of the handle body 1. Steel balls 4 are provided on the upper edges of both ends of the handle body 1 of the handle A. The function of the steel balls 4 is to prevent the adapter 2 from falling off from the body 1 when the adapter 2 is moved along the handle body 1 (by mounting on the upper edge, Thus, the positional relationship between the steel ball 4 and the adapter 2 can be confirmed visually). A stopper hole 6 is provided in the central portion of the handle main body 1 to be engaged with or separated from the fixing ball 5 (made of steel). The fixed ball 5 is received in a receiving hole 7 through a coil spring 8. The receiving hole 7 is provided on the inner peripheral surface of the above-mentioned mounting hole 3 on the adapter 2. The fixed ball 5 is received and installed in the adapter 2 in the following manner. The fixed ball 5 is biased outward from the inner peripheral surface (gp, inside the mounting hole 3) of the mounting hole 3 through the coil spring 8 and is continuously continued to the circumferential side of the fitted handle body 1 through the mounting hole 3. Crimp. ♦ In addition, the adapter 2 has an insert body 10 which is fitted and fitted to the sleeve 9. The insert body 10 includes a fixed ball 11 which is biased in a protruding direction according to a spring action. The fixed ball 11 and the sleeve 9 (or extended) The wall surface of the corner hole 12 in the rod) is crimped, and the adapter 2 and the sleeve 9 are reliably assembled. Then, if a large torque is required during the tightening operation and the loosening operation of the nut, etc., the adapter 2 is moved to one end side of the handle main body 1, the nut and the like are combined with the adapter 2, and the handle is passed through the handle. The driving force generated by the main body 1 for the adapter 2 can generate a strong torque, and tighten or loosen the screw nut. In addition, during this operation, the adapter 2 centered on the handle body 1 is not rotated, so that the operation can be performed smoothly.
又，如果將適配器2配置於把手主體1的中央位置，收 納安裝於適配器2上的固定球5就固定於把手主體i側的阻 止孔6中，形成所謂的T字形的把手，能進行螺母等的驅動 作業，此時通過在適配器2上連接加長桿能使其更近似於T 200526378 字形的把手。 實施例中的把手主體1是使該把手主體1的截面橢圓形 的最寬徑部（長軸）沿水準方向配置的（由第1圖的雙點劃線 以及第2圖的截面形狀就可明顯看出），這是因爲適配器2 側配置的固定球5所固定（配合）的阻止孔6合適地形成於棒 桿狀的該把手主體1的周側面（下端部）（收納孔7同時收納了 固定球5和線圈彈簧8，形成收納孔7的主體1的周側面越 接近於平面越容易形成，也就是，弧度小的圓曲面比弧度大 的圓曲面比較容易形成收納孔7，能使收納孔7的開口邊緣 形成於比較靠下的位置），即使賦予扭矩（驅動力），至少比短 軸側難以彎曲，可期待耐久性。 (五）圖示簡單說明 第1圖是表示局部截面前視圖。 第2圖是以截面表示把手主體的第1圖的側視圖。 元件符號說明 1 把手主體 2 配配器 3 裝配孔 4 鋼球 5 固定球 6 阻止孔 7 收納孔 8 線圈彈簧 9 套筒 200526378 10 插入體 11 固定球 12 角孔 -9-In addition, if the adapter 2 is disposed at the center of the handle body 1, the fixing ball 5 accommodated in the adapter 2 is fixed in the blocking hole 6 on the i side of the handle body, forming a so-called T-shaped handle, which can be used for nuts, etc. At this time, by connecting an extension rod to the adapter 2, it can be more similar to a T 200526378 shape handle. The handle main body 1 in the embodiment is arranged in the horizontal direction with the widest diameter portion (long axis) of the elliptical cross-section of the handle main body 1 (the two-dot chain line in FIG. 1 and the cross-sectional shape in FIG. 2 may be sufficient). Obviously, this is because the stopper hole 6 fixed (fitted) by the fixing ball 5 arranged on the adapter 2 side is suitably formed on the peripheral side (lower end portion) of the handle body 1 in the shape of a rod (the storage hole 7 is simultaneously stored) With the fixed ball 5 and the coil spring 8, it is easier to form the peripheral side of the main body 1 forming the receiving hole 7 closer to the plane, that is, a circular arc with a small arc is easier to form a receiving hole 7 than a circular curve with a large arc, which enables The opening edge of the storage hole 7 is formed at a relatively lower position), and even if torque (driving force) is applied, it is harder to bend than at least the short axis side, and durability can be expected.
