Abstract: An impact tool head is provided and configured to be disposed on a front end of an impact tool. The impact tool head includes: a rod body and a flange radially protruding from the rod body. The flange includes an inclined flat surface facing toward the front end and an outermost peripheral edge. A contact position is defined as a position where the inclined flat surface contact with at least one projection of the impact tool. Wherein each of the at least one projection is a ball member, and as viewed in the axial direction, a ratio of a distance between the contact position and the outermost peripheral edge to a radius of the at least one projection is between 0.1 and 0.6.

Abstract: A retaining mechanism, and a holding sleeve and a rod tool including the same are provided. The holding sleeve is adapted to dispose around a body portion of a main body and can rotate relative to the body portion. A blocking member is disposed in at least one through hole of a first sleeve. A second sleeve is movable relative to and disposed around the first sleeve. The blocking member is controllably pressed by the second sleeve to be partially received in an annular groove of the body portion. An elastic member is disposed around and between the first sleeve the first and second sleeves. Before the second sleeve is mounted to the first sleeve, a part of the elastic member corresponds to the blocking member in a radial direction of the first sleeve and can limit the blocking member to locate in the through hole.

Abstract translation: 提供保持机构，以及包括该保持机构的保持套筒和杆工具。 保持套筒适于配置在主体的主体部分周围并且可相对于主体部分旋转。 阻挡构件设置在第一套筒的至少一个通孔中。 第二套筒相对于第一套筒可移动并且布置在第一套筒周围。 阻挡构件被第二套筒可控地按压以部分地容纳在主体部分的环形槽中。 弹性构件设置在第一和第二套筒之间并且在第一套筒之间。 在第二套筒安装到第一套筒之前，弹性构件的一部分在第一套筒的径向方向上对应于阻挡构件，并且可以限制阻挡构件定位在通孔中。
