[0090] In further embodiments of the present invention, see Figures 16 to 23 As shown, the handle includes: a first part 10, a spring 20 and a second part 30. The first part 10 is arranged in the through hole 61 by the outer side of the second cabinet door 6, the second part 30 is connected to the first part 10 by the inner side of the second cabinet door 6, the spring 20 is located on the inner side of the second cabinet door 6, and the spring 20 is sleeved on the first part 10.

[0091] In a further embodiment of the present invention, the first part 10 may be strip-shaped, and the first part 10 is disposed in the through hole 61. A protrusion 101 is formed at the end of the first part 10 close to the outer side of the second cabinet door 6. The diameter of the protrusion 101 is larger than the diameter of the through hole 61, so that the protrusion 101 can be exposed in the through hole 61.

[0092] In a further embodiment of the present invention, the protrusion 101 may be in a truncated cone, hemispherical, wavy, etc., and it only needs to have a diameter larger than the diameter of the through hole 61 and be exposed in the through hole 61 .

[0093] In a further embodiment of the present invention, the outer diameter of the spring 20 is greater than the diameter of the through hole 61 , so that the spring 20 can be prevented from being pulled out of the through hole 61 when the first part 10 is pulled out.

[0094] In a further embodiment of the present invention, the diameter of the second part 30 is greater than the outer diameter of the spring 20 , so that when the first part 10 is pulled out, the second part 30 can be prevented from being pulled out of the through hole 61 and the spring 20 can be prevented from being ejected from the second part 30 .

[0095] In a further embodiment of the present invention, the first part 10 and the second part 30 are connected by a threaded connection or a pin connection, etc., so as to connect the first part 10 and the second part 30.

[0096] Please continue to see Figures 1 to 8 As shown, when in use, the protrusion 101 exposed from the through hole 61 is pulled out, the first part 10 is also pulled out, the spring 20 is compressed on the inner side of the second cabinet door 6, and then the first part 10 is held to pull and open the second cabinet door 6. When not in use, the protrusion 101 is released, the compressed spring 20 is reset, and the first part is automatically retracted into the through hole 61, effectively hiding the handle.

[0097] In a further embodiment of the present invention, the handle may be replaced by other forms, such as adsorbing the second cabinet door 6 by a suction cup to open it, or the second cabinet door 6 has a certain gap and the cabinet door is opened through the gap.

[0098] In further embodiments of the present invention, see Figure 29 to Figure 32 As shown, the connection structure 40 includes a front half portion 402 and a rear half portion 403 , and the front half portion 402 and the rear half portion 403 are connected to form a hook shape with an opening 401 .

[0099] In a further embodiment of the present invention, after the second cabinet door 6 is installed to the cabinet body 1 , the second cabinet door 6 is connected with the hook-shaped connection structure 40 and the clamping structure 50 to realize the rotation of the second cabinet door 6 relative to the cabinet body 1 .

[0100] In a further embodiment of the present invention, when the second cabinet door 6 and the cabinet body 1 are rotatably in a closed state, that is, the second cabinet door 6 closes the cabinet body 1, as the second cabinet door 6 is gradually closed, the rear half 403 of the connecting structure 40 gradually contacts the clamping structure 50, and the front half 402 of the connecting structure 40 gradually forms a gap with the clamping structure 50, and the gap can be considered as a kind of accommodating space. Through the design of this form of the connecting structure 40, the second cabinet door 6 can effectively close the cabinet body 1 in the closed state. In addition, in this state, the second cabinet door 6 cannot be removed from the cabinet body 1.

[0101] In further embodiments of the present invention, see Figure 33 to Figure 35 As shown, when the second cabinet door 6 and the cabinet body 1 are rotatably in an open state, that is, the second cabinet door 6 opens the cabinet body 1 through the handle, as the second cabinet door 6 enters the open state from the original closed state, the gap originally formed by the front half 402 of the connecting structure 40 is gradually accommodated by the clamping structure 50, and finally contacts the clamping structure 50. The rear half 403 of the connecting structure 40 was originally in contact with the clamping structure 50 and gradually forms a gap, forming a new accommodating space.
