Embodiment

See also Fig. 1, be depicted as the overall structure schematic representation of lifting lock device in the utility model one mode of execution.In this mode of execution, the lifting lock device comprises limiting stopper 1, the lifting tip 2, lifting seat 3, spanner piece 4, ratchet control spanner 5, ratchet 6, position limit cycle 7, limited cover 8 and turning wrench 9.

The center portion of limiting stopper 1 is provided with slotted eye and is oval (shown in Fig. 2 a), also is provided with two fan-shaped buckles (shown in Fig. 2 b) on the next door of oval slotted eye at the reverse side of limiting stopper 1, is used for fixing and tightens limiting stopper 1.

The lifting tip 2 stretches into the oval slotted eye of limiting stopper 1.In this mode of execution, the lifting tip 2 comprises head end 21 and terminal 22 (as shown in Figure 3), and wherein, head end 21 ovalizes of the lifting tip 2 also match with the oval slotted eye of limiting stopper 1.

Lifting seat 3 fixedly blocks the lifting tip 2.In this mode of execution, the center portion of lifting seat 3 is provided with circular slotted eye, and the end 22 of the lifting tip 2 is also rounded and match with the circular slotted eye of lifting seat 3.

Spanner piece 4 and ratchet control spanner 5 (as shown in Figure 4) all are fixed in the inside that lifts seat 3.In this mode of execution, ratchet 6 (as shown in Figure 5) is positioned over the inside of lifting seat 3, and wherein, the gear of ratchet 6 coincide each other with the gear of ratchet control spanner 5 and is connected (as shown in Figure 6).In this mode of execution, for the sake of security, the user controls the rotation that spanner 5 is controlled ratchet 6 through ratchet, and controls the lifting tip 2 to reach the effect that safety is installed through the rotation of control ratchet 6.
