the cantilever is connected with the guide rail and can move up and down in the refrigerating chamber along the guide rail;

the layer rack is arranged in the refrigerating compartment and is erected on the cantilever;

the adjusting frame is fixed in the tank liner, is positioned at one side of the cantilever and is arranged in parallel with the guide rail; the adjusting frame is provided with a plurality of limiting holes which are vertically arranged at intervals; a kind of electronic device with high-pressure air-conditioning system

The locking piece is rotationally connected to the cantilever;

when the locking piece rotates, the locking piece can be clamped with the limiting hole so that the cantilever is relatively fixed on the adjusting frame, or the locking piece can be separated from the limiting hole so that the cantilever and the locking piece can move up and down relative to the adjusting frame;

a chute extending up and down is concavely arranged on the side wall of the adjusting frame facing the cantilever; the limiting hole is formed in one side wall of the sliding groove;

the locking piece stretches into the sliding groove, and when the locking piece rotates, the locking piece can slide up and down relative to the sliding groove.

2. The refrigerator as claimed in claim 1, wherein the locking member includes locking blocks and knobs provided separately at both sides of the cantilever;

the locking block is rotationally connected to the side wall of the cantilever facing the adjusting frame and is accommodated in the chute;

the knob is rotationally connected to the side wall of the cantilever far away from the adjusting frame, the knob is connected with the locking block and can drive the locking block to rotate so that the locking block is clamped with or separated from the limiting hole.

3. The refrigerator as claimed in claim 2, wherein one end of the locking block is formed with a rotation shaft, and the other end of the locking block is provided with a bayonet;

the rotating shaft is rotatably arranged on the cantilever in a penetrating way and is connected with the knob;

the bayonet is arranged on the side wall of the locking block facing the limiting hole;

when the locking block rotates, the locking block can be clamped with the limiting hole through the bayonet.

4. The refrigerator as claimed in claim 3, wherein an engagement portion having a flat shape is formed at an end of the rotation shaft adjacent to the knob; a limiting groove matched with the embedded part is concavely formed in the side wall of the knob facing the rotating shaft; the embedded part is inserted in the limit groove so as to prevent the knob from rotating circumferentially relative to the rotating shaft.

5. The refrigerator as claimed in claim 3, wherein a stepped surface is formed on a peripheral wall of the rotation shaft, the stepped surface being located at a side of the cantilever away from the knob;

an annular groove is formed between the step surface and the knob on the peripheral side of the rotating shaft;

the cantilever is provided with a shaft hole for the rotating shaft to pass through, and the periphery of the shaft hole is clamped in the annular groove.

6. The refrigerator as claimed in claim 2, wherein the knob has a driving arm protruding from a peripheral wall thereof to extend outwardly.

7. The refrigerator as claimed in claim 2, wherein the locking member further comprises an elastic member, one end of the elastic member being coupled to the locking block; the other end of the elastic piece is used for elastically leaning against the side wall of the chute opposite to the limiting hole so as to drive the locking piece to rotate and be close to the limiting hole.

8. The refrigerator as claimed in claim 7, wherein the elastic member includes an elastic arm and a fixing piece formed at one end of the elastic arm;

the fixing piece is provided with a mounting hole, and the fixing piece is fixedly arranged on the side wall of the locking block facing the adjusting frame through the mounting hole;

the elastic arms are distributed on one side of the locking block, which is far away from the limiting hole, and extend outwards.
