In order to make the two unlocking pieces 4 adapt to two groups of bottom plate locks 100 with different distances, if the positions of the two unlocking pieces 4 on the connecting shaft 8 are adjustable, on the basis of the above embodiment, a plurality of fixing grooves 81 are arranged on the connecting shaft 8 at intervals along the extending direction; the unlocking piece 4 and the sliding piece 2 are respectively connected with a fixed hook piece 9; the fixing hook piece 9 is configured to be hooked in one of the fixing grooves 81.
The fixed hook piece 9 is connected with the unlocking piece 4 and the sliding piece 2 through bolts. When the position of the unlocking piece 4 needs to be adjusted, the bolt is loosened, the fixing hook piece 9 is separated from the unlocking piece 4, then the position of the unlocking piece 4 is adjusted, two unlocking pieces 4 can be respectively aligned to two bottom plate locks 100 (the distance between the two bottom plate locks 100 can be measured firstly, and the positions of the two unlocking pieces 4 are adjusted according to the distance), then the fixing hook piece 9 is hung in the fixing groove 81 adjacent to the unlocking piece 4, and finally the fixing is locked and fixed through the bolt. The position adjustment of the connecting shaft 8 and the sliding member 2 is performed in the same manner as the above process, and will not be described herein.
This embodiment utilizes fixed hook piece 9 to connect unlocking piece 4 and connecting axle 8, slide 2 and connecting axle 8, can adjust the position of unlocking piece 4 and connecting axle 8, can realize unlocking piece 4 and connecting axle 8 again, slide 2 and connecting axle 8's fixed connection.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
