Reversing brake block body, invention control [previously, the internal body end is integrally provided with a steam-red and reversing function integrated module including the innovative structure formed by the cover plate] The characteristics of the trough, 9 201041700 to change the function of the cylinder and the airflow reversing function but the function is unchanged, so as to achieve the integration of the body structure, and can improve the working hours and reduce the defect rate, reduce the manufacturing cost and shorten the group efficiency. The practical progress and the preferred industry utilize the above-mentioned embodiments to disclose the present invention, and the specific scope is used to describe the present invention, and the scope of the present invention is well-known; The person who specializes in the field of technology and principles can understand the modification of the invention, such as the modification of the invention, and the purpose of modifying the n: effect ^ and this should be covered by the patent application as described later. The scope is within the boundaries. 〇 10 201041700 [Simple description of the drawings] Fig. 1 is a perspective view showing the combination of the reciprocating pneumatic tools of the present invention.
