Abstract: A connecting structure for assembly includes a body, an inserting part, a latching part, and a control part. The body has a plug hole and a guide slot disposed toward the plug hole. The inserting part is detachably plugged into the plug hole correspondingly and has a latching portion. The latching part is slidely connected to and guided by the guide slot; the latching part has a latching body latched to the latching portion correspondingly. The control part is disposed movably in the body and selectively drives the latching part to reciprocate along the guide slot. Therefore, the esthetic effects of covering and hiding each other for assembled plates and the effect of a smooth, labor-saving, and even rotation for the control part are obtained.

Abstract: A combinational bolt which comprises a screw unit and a sleeve unit. The screw unit has a plurality of threads on a surface of a front terminal, the threads make the screw unit connect with a target object, another terminal of the screw unit forms a first concave portion. The sleeve unit, which is set inside the target object, also connects and surrounds the screw unit. A sink-proof portion is set on the surface of one terminal of the sleeve unit, the sink-proof portion makes the sleeve unit clamp onto the target object, and the outer surface of the sleeve unit has a plurality of strengthen circle units and a plurality of cut slots, and a second concave portion forms inside the sleeve unit, the first concave portion and the second concave portion clamp together.
