摘要： The present invention relates to a joint adapter for a power drill screw driver having a driving shaft, a slide socket, a compression spring, a packing ring and a screw driver bit. The driving shaft is provided with an insertion groove and an insertion piece. A neck is located in the middle of the driving shaft. A strong magnet is fixed at the front end of the axial insertion hole. A clamping ring is arranged at a proper place of the axial insertion hole. The compression spring is inserted around the neck of the driving shaft and rests on the clamping ring of the slide socket. The packing ring closely sits at the end of the neck of the driving shaft in a tight state while the compression spring presses against the packing ring so that the compression spring and the slide socket are located in place. A plurality of screw driver bits in a plurality of shapes and sizes each being selectively inserted into the insertion groove of the driving shaft for tightening the screws.

摘要： A precision screwdriver having a handle with a rotatable portion consisting of a shaft, a handle, a thrust ring and a rotatable cap. The handle has a cylindrical portion with a raised edge formed on its outer surface, and an internal cavity. The rotatable cap is equipped with a hole therethrough for holding a bearing in the form of a single ball. An internal groove disposed at near the hole serves a securing function when the raised edge of the cylindrical portion of the handle is fitted to the rotatable cap internal groove. A concave securing plate with a hole therethrough is disposed on the outer edge of the rotatable cap hole. The securing plate serves to position the bearing with suitable surface exposed through the securing plate hole. Thus, the rotatable cap can be fitted onto the cylindrical portion of the handle and properly secured by mating the raised edge with the internal groove. The bearing is inserted into the rotatable cap hole through the top of the rotatable cap and is retained between the handle cavity and the rotatable cap by the securing plate. In use, the index finger is placed on the exposed bearing which serves as a rotating point. Consequently, when pressure is applied, the shaft and handle revolve independently of the rotation of the bearing and the rotatable cap.

摘要翻译： 一种具有手柄的精密螺丝刀，其具有由轴，手柄，止推环和可旋转盖组成的可旋转部分。 手柄具有圆柱形部分，其外表面上形成有凸起的边缘，以及内部空腔。 旋转盖配备有穿过其中的孔，用于保持单个球形式的轴承。 当把手的圆柱形部分的凸起边缘装配到可旋转的帽内部凹槽时，设置在孔附近的内部凹槽具有固定功能。 在可旋转盖孔的外边缘上设有一个带有孔的凹形固定板。 固定板用于通过固定板孔露出合适的表面定位轴承。 因此，可旋转盖可以装配到手柄的圆柱形部分上，并且通过将凸起边缘与内部凹槽配合来适当地固定。 轴承通过可旋转盖的顶部插入可旋转的盖孔中，并通过固定板保持在手柄腔和可旋转盖之间。 在使用中，食指放置在作为旋转点的外露轴承上。 因此，当施加压力时，轴和手柄独立于轴承和可旋转盖的旋转而旋转。
