A locking device includes a clamp (1), whose curled middle forms an axial mounting hole (2). An upper project (111) projects on the left end (11) of the clamp (1), and a lower project (121) projects on the right end (12) of the clamp (1). A middle gap (31) is formed between the upper project (111) and the lower project (121), a left gap (32) is formed between the left end (11) and the lower project (121), and a right gap (33) is formed between the right end (12) and the upper project (111). An upper lug (112) projects at the outside of the upper project (111), a lower lug (122) projects at the outside of the lower project (121), the positions of the upper lug (112) and the lower lug (122) correspond to each other from upper to down. An upper guiding slope (113) and a lower guiding slope (123) are disposed at the upper project (111) and the lower project (121) respectively. A bolt-nut mechanism or a screw axially extends through a through hole (115) of the upper lug (112) and a mounting hole (125) of the lower lug (122) so as to lock the upper lug (112) and the lower lug (122) and seal the middle gap (31). The contact fitting of the upper guiding slope (113) and the lower guiding slope (123) leads to the circumferential movement of the upper project (111) and the lower project (121) so as to reduce the left gap (32) and the right gap (33), thereby making the clamp (1) lock the subject inside the axial mounting hole (2). The locking device has a simple construction, a low cost and a secure connection structure. |
