The fixing member 32 further has a first thread structure T1, and the outer side or the outer edge of the receiving portion 21 has a second thread structure T2, which are matched with each other. Referring to FIGS. 4A and 4B, the spherical structure 311 of the connecting member 31 is disposed in the receiving portion 21, and the first threaded structure T1 of the fixing member 32 and the second threaded structure T2 of the receiving portion 21 are locked and coupled. The second display module 20 is firmly locked to the connection mechanism 30.

In more detail, referring to the cross-sectional views of the connecting member 31 and the second display module 20 of FIGS. 4A and 4B , the spherical structure 311 of the connecting member 31 passes through the fixing member 32 and is partially disposed in the receiving portion 21 for use. The fixing member 32 can be rotated, and the rotation direction R1 as shown in FIG. 3 is rotated relative to the accommodating portion 21 to move/rotate the fixing member 32 from a releasing position X0 (first position; FIG. 4A) to one. a fixed position X1 (second position; FIG. 4B), at this time, a first inclined surface S1 of the inner edge of the fixing member 32 abuts against the central axis O of the fixing member 32 and presses the outer side or the outer edge of the receiving portion 21 A second inclined surface S2 deforms and reduces the inner diameter of the opening of the accommodating portion 21 so that the inner edge of the opening abuts and tightly engages the spherical structure 311. Thus, the second display module 20 and the first display module 10 are firmly fixed by the combination of the first and second screw structures T1 and T2 and the first slope S1 abutting the second slope S2 for display. The device assumes a locked state.

When the user wants to adjust the angle or position of the second display module 20 relative to the first display module 10, the fixing member 32 can be rotated in the rotation direction R2 (refer to FIG. 3) opposite to the rotation direction R1. The fixing member 32 is disengaged from the fixing position X1, and the connecting member 31 is no longer tightly fixed with the receiving portion 21, and the second inclined surface S2 is no longer pressed by the first inclined surface S1 in the direction of the central axis O at the fixed position X1. The accommodating portion 21 is no longer tightly fastened to the spherical structure 311, and the user can rotate the second display module 20 at this time. In other words, when the spherical structure 311 is located in the accommodating portion 21, and the fixing member 32 is not at the fixed position X1, the fixing member 32 is between the releasing position X0 or the releasing position X0 to the fixed position X1, at which time the display device 1 presents In the half-locked state, the second display module 20 can be rotated or moved relative to the first display module 10.

It should be noted that the fixing member 32 also includes a clamping portion 322. As shown in FIG. 4A, the clamping portion 322 clamps the spherical structure 311 of the connecting member 31, wherein the clamping portion 322 to the fixing member 32 The shortest distance of the central axis O is smaller than the shortest distance from the first thread structure T1 of the fixing member 32 to the central axis O, which ensures that the fixing member 32 firmly holds the spherical structure 311 at the fixed position X1.

5 is a schematic cross-sectional view of the connecting mechanism 30. The connecting member 31 of the connecting mechanism 30 and the receiving portion 32 of the second display module 20 in the present embodiment have a hollow structure, so that a circuit module The W (or the electric wire, the signal line) can be connected to the first display module 10 from the second display module 20 through the accommodating portion 21, the fixing member 32 and the connecting member 31, so that the circuit module W is buried. The second display module 20, the connection mechanism 30 and the first display module 10 are not exposed, which not only enhances the appearance of the display device 1, but also eliminates the need for the line to be arranged around the device, thereby causing the user to need to organize the line. Improve the convenience of use.

6 and 7 are schematic diagrams showing the second display module 20 being rotatable relative to the first display module 10, wherein FIG. 6 is a view showing the second display module 20 being rotatable up and down (rotating around the Y axis), 7th The figure shows that the second display module 20 can be rotated left and right (rotating around the Z axis). Of course, the second display module 20 is rotated by the uniaxial axis, by the spherical structure 311 of the connecting member 31, and second. The display module 20 can be rotated in a full circumference. When the fixing member 32 is away from the fixed position X1 on the receiving portion 21 (for example, to the loose position X0), the second display module 20 can be rotated relative to the first display module 10 by applying a force, wherein It is worth mentioning that the user can change the degree of rotation of the second display module 20 relative to the first display module 10 by adjusting the degree of tightness of the fixing member 32 to the receiving portion 21. For example, when the fixing member 32 is on the accommodating portion 21 and close to the fixed position X1 end, the second display module 20 is more tightly closed than the first display modulo when it is closer to the detaching position X0 end. The group 10 is rotated, that is, more force must be applied to rotate the second display module 20. On the contrary, when the fixing member 32 is closer to the releasing position X0, the user is more likely to rotate the second display module 20. The degree of tightness of the second display module 20 relative to the first display module 10 can be adjusted by the user rotating the fixing member 32.
