Furthermore, the guide shaft 53 is provided with a guide limit portion 531 which is in sliding contact with the side of the matching seat 3 facing away from the movable seat 5 on the end thereof away from the movable seat 5. The guide limit portion 531 is used to limit the guide shaft 53 from being separated from the matching seat 3, thereby ensuring the stability of the guidance of the guide shaft 53.

[0038] As a preferred embodiment, the fixed seat 2 is provided with a plurality of fixed connecting ears 23, and the fixed connecting ears 23 are used to cooperate with the first bolt to be fixed to the horizontal plate 9; the movable plate 1 is provided with a movable connecting ear 11, and the movable connecting ear 11 is used to cooperate with the second bolt to be fixed to the cabinet door 8.

[0039] As a preferred embodiment, the fixing base 2 is provided with at least two first connection holes 26, and the mounting plate 4 is provided with a plurality of second connection holes 41 corresponding one-to-one with the first connection holes 26. A fixing fastener is provided between the corresponding first connection holes 26 and the second connection holes 41 to secure the fixing base 2 and the mounting plate 4 together. Specifically, the fixing fastener is a fastening bolt, wherein the first connection hole 26 is a countersunk hole and the second connection hole 41 is a threaded hole. The head of the fastening bolt is located in the first connection hole 26, and at least a portion of the screw end is threadedly engaged with the second connection hole 41, thereby securing the fixing base 2 and the mounting plate 4 together through the action of the fastening bolt.

[0040] In this embodiment, the mating seat 3 is provided with a plurality of first avoidance holes 36 corresponding one-to-one to the first connecting holes 26. The first avoidance holes are used to avoid the screw section of the fastening bolt, so that the fastening bolt can pass through the mating seat 3 to combine the fixing seat 2 and the mounting plate 4 together.

[0041] In this embodiment, the mounting plate 4 is provided with a mounting positioning protrusion 42, and the fixing seat 2 is provided with a mounting positioning groove 27. Each mounting positioning protrusion 42 is positioned and fitted in a mounting positioning groove 27, thereby achieving positioning between the mounting plate 4 and the fixing seat 2, and then connected using fastening bolts.
