Preferably, the elastic compression piece 181 is a gas spring.

[0068] In the embodiment, the second mounting portion 18 can be a component independent of the first mounting portion 11, or can be the same component as the first mounting portion 11, which is used for mounting the elastic compression piece 181.

[0069] In the embodiment, the hinged point of the elastic compression piece 181 and the connecting arm is located in the region between the hinged shaft 184 and the connecting shaft 191, which means that the projection of the hinged point on the plane in which the axis of the hinged shaft 184 and the axis of the connecting shaft 191 are located is located between the axis of the hinged shaft 184 and the axis of the connecting shaft 191. In the embodiment, since the elastic compression piece 181 is connected between the driving arm 19 and the hinged shaft 184, the driving arm 19 will be pushed by the thrust force from the elastic compression piece 181 to abut against the first limiting column 182 or the second limiting column 183, thereby fixing the driving arm 19, i.e. fixing the first connecting piece 131 connected with the driving arm 19, at this time, the position of the third connecting piece 141 connected with the first connecting piece 131 and the connecting portion 12 connected with the third connecting piece 141 is also fixed, i.e. the position of the drawer structure 2 can be fixed.

[0070] In addition, in the first connecting arm 13 oscillation process, the driving arm 19 will swing with the first connecting piece 131, and because the first limiting post 182 and the second limiting post 183 are respectively located on both sides of the plane of the axis of the connecting shaft 191 and the axis of the hinge shaft 184, therefore, in the process of the driving arm 19 moving from abutting against the first limiting post 182 to abutting against the second limiting post 183, and moving from abutting against the second limiting post 183 to abutting against the first limiting post 182, the elastic compression member 181 will be gradually compressed, that is, to prevent the driving arm 19 from rotating, until the elastic compression member 181 and the hinge point of the driving arm 19, the connecting shaft 191 and the hinge shaft 184 are located on the same straight line, at this time, it is the critical point, the compression reaches the maximum, after passing the critical point, the elastic compression member 181 will gradually stretch, that is, to push the driving arm 19 to rotate, until the driving arm 19 abuts against the second limiting post 183 or the first limiting post 182, it can be seen that when the user pulls out or pushes back the drawer type structure 2 from the furniture or household appliances, after passing the critical point, the pushing force of the elastic compression member 181 on the driving arm 19 can assist the pulling out or pushing back process, and can improve the convenience of the pulling out or pushing back process of the drawer type structure 2 to a certain extent.
