| Zusammenfassung: | The utility model relates to a manual locking device for jointed boards, which comprises a positioning support bar and is characterized in that a screw barrel is arranged at one end of the positioning support bar, and a threaded rod matched with the screw barrel to be used is arranged on the screw barrel. One end of the threaded rod is connected with a sleeve sleeved on the positioning support bar through a baffle, a positioning sleeve is sleeved on the other end of the positioning support bar, and positioning holes are arranged on the positioning support bar. The manual locking device can effectively meet requirements of manufacture by splicing scattered small boards into a bigger board. |
