And if the lubrication hole 124 is inclined to fit the inner small outer large-class hole design, the oil is located in the empty space. If the sleeve is rotated and thrown, the inner diameter hole is smaller, and the amount of oil that leaks out is smaller. The rotating impact guard head stops acting, and the current air out 'out to the power tool chamber to the Lin oil' can be quickly recirculated by the outer diameter hole of the larger aperture. The above-mentioned use of the rib directly formed on the upper and lower planes of the sleeve, instead of the conventional structure of the movable pin wf* 'overcoming the long-standing technical problems of the conventional structure, and the expected structural efficiency, is summarized as follows: The use of the sales components makes the structure of the impact tool head more streamlined, and the overall cost is more competitive in the market. Secondly, the elimination of the swaying pin can also simplify the assembly steps (complexity) of the impact tool head component, greatly improve the assembly speed of the impact I head, and satisfy a large and rapid production trend. Second, the use of ribs directly formed in the sleeve accommodation space limit impact Long does not know the use of the swaying pin member, the end cover surface deformation required to penetrate the end cover affects the viewing problem. Fourth: Utilizing (4) the ribs directly formed by the upper and lower planes, there is no practical use of the semi-circular groove of the limit moving pin, and the semi-circular positioning groove drilling and milling The problem of excessive rate and even the deviation of drilling and milling accuracy leads to the problem that the pinning pin is not easy to wear or can not be worn. The fifth: the sleeve directly forms the rib of the limit impact block, and the end cap is additionally prevented from penetrating through the positioning hole. Affect the end cover viewing problem. Sixth: The sleeve is provided with lubrication holes to fill the lubricating oil to the accommodating space, which can ensure the lubrication effect of the impact block and the output shaft, prolong the service life of the component and reduce the decibel effect of the impact noise. Seventh: The design of the small hole in the lubrication hole is helpful to accommodate the amount of lubricant leakage in the space and the rapid reflow effect of the lubricating oil that helps to exude to the power tool chamber to meet Short-time driven component lubrication. Summarizing the above embodiments, the present invention provides a rotary impact tool head that can be loaded into a power tool, and a two-ribbed rib is integrally formed in a barrel-shaped sleeve so that the two impact blocks can be more closely combined in the sleeve. In the cylinder, the situation that the rib is damaged due to the reaction force of the party impact block is reduced, the stability of the creation is improved, and the complexity of the structure is reduced; the sleeve is provided on the side away from the bottom plate to cover the end cover. The opening is such that the two impact blocks can be placed in the accommodating space from the side of the sleeve away from the bottom plate, so that the creation is easier to assemble under the simplification of the structure, which is highly advanced.
