When the operation is not suitable, such as power failure, rain, snow, etc., during the sliding operation, the sliding operation needs to be stopped manually, but the operation is fixed only by the stability of the truss, so that the safety is not high. For this purpose, the truss can be tensioned by manually operating the locking and locking device 7 so as to play a role of an auxiliary stabilizing system. Manual locking can be through screwing up locking bolt 16 with wedge 15 to 8 directions of slide rail top advances, slide rail 8, locking bolt 16, wedge 15, locking device casing 17 become a fastening an organic whole when wedge 15 and slide rail 8 closely push up tightly, have played the effect of fixing locking device 7 to on the slide rail 8, have realized interim manual fastening effect.
When the fault is eliminated and the sliding is required to be continued, the reset bolt 18 pushes the wedge block 15 downwards to reset, and then the reset bolt 18 returns to the original position. And simultaneously, the wedge block limiting plate 13 and the limiting plate fastening bolt 14 are loosened so that the reset bolt 18 can move downwards relative to the slide rail 8, and after the operation is finished, the sliding operation is continued after the components are reset.
