The locking end 112, 122 of the pressing member, and the first locking member 11 has a hollow structure, the hollow structure penetrates the wearing end 111 of the first locking member 11 and forms a mating cavity 113. The mating cavity 113 has an internal thread 114 therein. The insertion end 121 of the second locking fastener 12 has an external thread 124 that cooperates with the internal thread 114, so that in use, the first locking member 11 is inserted from one side of the side-by-side article so that the wearing end of the first locking member 11 The 111 is located in the side-by-side article, and at the same time, the second fastener 12 is inserted from the other side of the side-by-side article, and the wearing end 121 of the second fastener 12 is extended toward the docking chamber 113. At least one of the first locking member 11 and the second locking member 12 causes the external thread 124 of the second locking member 12 to cooperate with the internal thread 114 in the mating cavity 113 to extend into the mating cavity 113, thereby making the side by side good. The object is locked between the locking end 112 of the first locking member 11 and the locking end 122 of the second locking member 12, The purpose of the locking assembly 10 of the present invention for locking different objects together; it is worth mentioning that the locking length of the first locking member 11 and the second locking member 12 (ie, the internal thread of the first locking member 11) The length of the 114 and the length of the external thread 124 of the second fastener 12 are equal to the length of the piercing end 121 of the second fastener 12, so that the locking assembly 10 of the present invention overcomes the conventional bolt and nut due to the shorter locking length. There is a problem that the lock is not stable and is easy to loose. Wherein the junction of the first lock 11 is made The design of the first locking member 11 is in the shape of a barrel, and it can be understood that in other embodiments, the hollow structure can also penetrate the locking end 112 of the first locking member 11 . The manufacturing cost is reduced by reducing the material usage of the first lock member 11. More specifically, as follows: at least one of the locking ends 112, 122 of the first locking member 11 and the second locking member 12 has a cooperation with an external tool (such as a screwdriver or a wrench) to screw in or out the locking end. 112, 122 for the mating structure 115, 125, so that the operator can screw in or out the first lock 11 and the second lock 12; in this embodiment, the first lock 11 and the second lock 12 are It has a mating structure 115, 125 to facilitate the operation of the first lock 11 and the second lock 12 by the operator, and the locking structures of the mating structures 115, 125 are located at the first lock 11 and the second lock 12. At the end of the end 112, 122 (ie, the mating structure 115 is located at the end of the locking end 112 of the first fastener 11 and the mating structure 125 is located at the end of the locking end 122 of the second fastener 12), To further reduce the space occupied by the first lock 11 and the second lock 12; wherein the mating structures 115, 125 are a groove-shaped groove structure, a cross-shaped groove structure, a polygonal groove structure or a polygonal convex structure, To simplify the structure of the mating structures 115, 125, of course, the mating structures 115, 125 Configuration is not limited thereto, and may be other structures designed according to the actual needs.
