The fitting structure comprises a first device (22), a second device (33) and a position-limiting device (11) configured to fixedly connect the first device (22) and the second device (23), wherein the position-limiting device (11) comprises a pre-fitting stepped portion (113) which is provided in the first device (22), and a threaded portion (111) and a relief groove portion (112) which are provided in the second device (33), and the relief groove portion (112) is arranged between the pre-fitting stepped portion (113) and the threaded portion (111); a height of the relief groove portion (112) is set so that the pre-fitting stepped portion (113) is in contact with a fixing face which is an end face of the second device (33) which is fixedly connected by the position-limiting device (11). The fitting structure can solve a problem of a gap between an end face of the base and an end face of the rear casing being increased when the base is subjected to a force. ## Claims ### Claim 1 A fitting structure, comprising a first device, a second device, and a position-limiting device configured to fixedly connect the first device and the second device, wherein the position-limiting device comprises a pre-fitting stepped portion which is provided in the first device and a threaded portion and a relief groove portion which are provided in the second device, and the relief groove portion is arranged between the pre-fitting stepped portion and the threaded portion; the position-limiting device further comprises a position-limiting stepped portion which is arranged between the pre-fitting stepped portion and the relief groove portion and is located in the first device; and a height of the relief groove portion is set so that the position-limiting stepped portion is in contact with a fixing face which is a face of the second device which is fixedly connected by the position-limiting device; and wherein the fitting structure further comprises a positioning device configured to connect the first device and the second device, a slot corresponding to the positioning device is disposed at the bottom of the second device, so that the first device is fixed onto the second device by inserting into the slot of the positioning device, and an inserting direction of the positioning device in the second device is perpendicular to an inserting direction of the position-limiting device in the second device. ### Claim 2 (depends on 1) The fitting structure according to claim 1, wherein the height of the relief groove portion is equal to or less than 0.05 mm. ### Claim 3 (depends on 2) A display device, comprising the fitting structure according to claim 2. ### Claim 4 (depends on 3) The display device according to claim 3, further comprising a display screen and a base, wherein the display screen is secured to the base by the fitting structure. ### Claim 5 (depends on 1) The fitting structure according to claim 1, wherein the threaded portion and the relief groove portion are completely fixed in the second device, while the pre-fitting stepped portion is completely fixed in the first device. ### Claim 6 (depends on 1) The fitting structure according to claim 1, wherein the position-limiting stepped portion has a diameter which is greater than a maximum outer diameter of the threaded portion. ### Claim 7 (depends on 1) The fitting structure according to claim 1, wherein the relief groove portion has a diameter which is equal to or less than a minimum inner diameter of the threaded portion. ### Claim 8 (depends on 1) The fitting structure according to claim 1, further comprising a third device through which the position-limiting device fixedly connects the first device and second device, so that a contacting face is formed between the first device and the third device without a gap. ### Claim 9 (depends on 8) The fitting structure according to claim 8, wherein the position-limiting device is arranged to be closer to the contacting face. ### Claim 10 (depends on 8) The fitting structure according to claim 8, wherein an inserting direction of the position-limiting device into the first device is parallel to the contacting face. ### Claim 11 (depends on 8) The fitting structure according to claim 8, wherein the third device is a casing. ### Claim 12 (depends on 1) The fitting structure according to claim 1, wherein the fitting structure comprises two position-limiting devices. ### Claim 13 (depends on 1) The fitting structure according to claim 1, wherein the first device is a base, and the second device is a base securing bracket. ### Claim 14 (depends on 1) A display device, comprising the fitting structure according to claim 1. ### Claim 15 (depends on 14) The display device according to claim 14, further comprising a display screen and a base, wherein the display screen is secured to the base by the fitting structure.
