The supporting portion 223 is received in the receiving groove 230 in the engaged state, and the display end 100 can be placed on the host end 200 in the unfolded state, so that the display end 100 can be respectively contacted with the supporting portion 223 and the main body portion 210.

Referring to fig. 9, in an embodiment, the main body 210 has a handle slot 260 penetrating through the sidewall 215 and communicating with the accommodating slot 230, and the supporting portion 223 protrudes out of the handle slot 260 in the fastening state. With the above structure, the user can insert the finger tip into the finger-gripping groove 260 to conveniently turn the supporting frame 220 out of the accommodating groove 230. The provision of the handle slot 260 also facilitates the user to separate the display end 100 from the host end 200. For example, when the display end 100 is stacked on the body portion 210, the user's fingertips can be inserted into the handle slot 260 to facilitate the removal of the display end 100 from the host end 200.

Further, referring to fig. 4, side wall 215 of host end 200 includes opposing front and

rear walls

2151, 2153, and opposing left and

right walls

2155, 2157, left wall 2155 being located between front and

rear walls

2151, 2153, right wall 2157 being located between front and

rear walls

2151, 2153, front wall 2151 being located between left and

right walls

2155, 2157, and rear wall 2153 being located between left and

right walls

2155, 2157. The receiving groove 230 penetrates the front sidewall 2151. Referring to fig. 12 and 13, the mounting groove 250 is obliquely provided in the main body 210, the support part 223 can contact the rear sidewall 2153 in the unfolded state, and the rotating part 221 can slide in the mounting groove 250 to change the contact position of the support part 223 with the rear sidewall 2153, thereby changing the inclination angle between the support part 223 and the main body 210.

Specifically, referring to fig. 12 and 13, when the supporting portion 223 is turned over from the accommodating groove 230, the supporting portion 223 drives the rotating portion 221 to rotate in the mounting groove 250, and when the end of the rotating portion 221 is located at a certain depth of the mounting groove 250, the rotating portion 221 drives the supporting portion 223 to turn over a certain angle (set to x), and then the supporting portion 223 contacts the rear sidewall 2153, so that the supporting portion 223 is positioned on the main body portion 210, and the supporting portion 223 and the main body portion 210 form a certain inclination angle (set to y). The rotating part 221 can further slide along the mounting groove 250 during the rotation process, and when the rotating part 221 slides into a deeper position of the mounting groove 250, the supporting part 223 turns an angle smaller than x to contact the rear sidewall 2153, and the inclination angle between the supporting part 223 and the main body part 210 is larger than y. With the above structure, the inclination angle of the support portion 223 on the main body portion 210 can be conveniently changed, so as to conveniently adjust the inclination angle of the display end 100 on the main body portion 210.

The protrusion 214 prevents the rotating portion 221 of the supporting frame 220 from slipping in the mounting groove 250, which facilitates the reliable positioning of the supporting frame 220 on the main body portion 210. It can be understood that there may be a plurality of protrusions 214, the plurality of protrusions 214 are distributed at different positions of the mounting groove 250, and when the rotating portion 221 contacts with different protrusions 214, the inclination angles of the supporting portion 223 and the main body portion 210 are different, which is beneficial to positioning the supporting frame 220 at different positions, and can improve the convenience of the user.

Further, referring to fig. 4 and 5, the main body 210 may include a third suction member 216, the third suction member 216 is disposed on the main body 210 at a position close to the rotation portion 221, and the third suction member 216 is used to be sucked to the display terminal 100 in the unfolded state to prevent the display terminal 100 from sliding on the main body 210. Specifically, the third adsorption member 216 may be a magnet. The side circumference 115 of the display end 100 may be provided with a magnet or an iron piece, so that when the display end 100 is obliquely placed on the main body 210 and supported by the supporting portion 223, the side circumference 115 of the display end 100 can be attracted to the third attraction member 216, so that the display end 100 can be reliably positioned on the column portion, and the display end 100 and the main body 210 are prevented from slipping. It can be understood that when the periphery of the display end 100 is made of a ferromagnetic material, such as stainless steel, the display end 100 can be attached to the third absorbing member 216 without providing any other absorbing structure, thereby facilitating the positioning of the display end 100 on the main body portion 210.
