The head of the telescopic sleeve 30 is located outside the head of the fixed sleeve 20, a cylindrical accommodating cavity is formed in the head of the telescopic sleeve 30, and the rotating sleeve 40 is installed in the cylindrical accommodating cavity and has a certain gap with the cavity wall of the accommodating cavity, so that the rotating sleeve 40 can rotate relative to the telescopic sleeve 30, and preferably, a bearing 33 is installed between the tail of the rotating sleeve 40 and the telescopic sleeve 30 to reduce the resistance of the rotating sleeve 40 in rotating relative to the telescopic sleeve 30.

The transmission mechanism 60 includes a drive shaft 61 and a drive sleeve 62; the driving shaft 61 is located in the telescopic sleeve 30 and fixed to the tail end of the rotating sleeve 40, the tail of the driving sleeve 62 is provided with a flange, and the driving sleeve 62 is fixed on the mounting plate 10 through a fastener penetrating through the flange and coaxially opposite to the driving shaft 61. Two guide surfaces 611 which are spirally extended and arranged in the circumferential direction are formed on the driving shaft 61, two top protrusions 621 are formed at the head of the driving sleeve 62, the circumferential arrangement angle of the two top protrusions 621 is consistent with the circumferential arrangement angle of the two guide surfaces 611 on the driving shaft 61, and the two top protrusions 621 are respectively matched with the two guide surfaces 611 correspondingly.

A torsion butterfly spring is used as the second return element 72, the second return element 72 being arranged between the telescope housing 30 and the stationary housing 20, the second return element 72 being adapted to provide a return of the drive shaft 61 after the torsion force has been removed and the drive shaft 61 is twisted.

The first magnetic member 51 comprises two magnets 511 which are spliced together, preferably, the two magnets are in a semi-cylindrical structure, the two magnets are spliced together to form a cylindrical structure, and the two magnets 511 are arranged in a way that the opposite magnetic poles face the same direction, namely, the N pole and the S pole of the two magnets 511 are positioned on the same end face of the first magnetic member 51; the head of the rotating sleeve 40 is formed with a cylindrical receiving cavity, the first magnetic member 51 is mounted in the receiving cavity, and a groove 931 is provided on the outer periphery of the magnet, a protruding strip 932 is formed on the cavity wall of the cylindrical receiving cavity, and the protruding strip 932 is matched with the groove 931 to enable the two magnets of the first magnetic member 51 to be limited to rotate relative to the rotating sleeve 40. Preferably, the end of the first magnetic member 51 is made approximately flush with the head of the rotating sleeve 40, so that the head of the rotating sleeve 40 is slightly lower than the head of the telescopic sleeve 30.

Based on the above, when the head of the telescopic sleeve 30 is pressed to a certain degree, the telescopic sleeve 30 performs the retracting movement, as shown in fig. 3 and fig. 4, which makes the top protrusion 621 of the driving sleeve 62 act on the guiding surface 611 with a certain pushing force, so as to force the driving shaft 61 to twist, and the driving shaft 61 drives the rotating shaft to twist, so as to drive the first magnetic member 51 to twist. As shown in fig. 1 and 2, after the pressure on the telescopic sleeve 30 is released, the first restoring member 71 pushes the telescopic sleeve 30 to extend and restore, and in the process, the second restoring member 72 makes the rotating shaft reverse-twist to restore the first magnetic member 51 to the initial angle.

As shown in fig. 2 and 4, a first stopping section 921 is provided on a cavity wall of the cylindrical receiving cavity of the telescopic sleeve 30, a second stopping section 922 is provided on an outer circumference of the rotating sleeve 40 corresponding to the first stopping section 921, and after the rotating sleeve 40 rotates, the first stopping section 921 limits a final torsion angle of the rotating sleeve 40 by stopping the second stopping section 922. The final twist angle is defined in the range of 100 ° to 150 ° by properly arranging the circumferential positions of the first and

second stopper sections

921 and 922.

The second magnetic member 52 is disposed behind the display body 200, and specifically, as shown in fig. 5 and 6, the support member 201 is fixed to the back of the display body 200, the insertion hole 202 is formed on the support member 201, the second magnetic member 52 is fixed to the bottom of the insertion hole 202, and the second magnetic member 52 is identical to the first magnetic member 51 in structure, that is, the second magnetic member 52 includes two semi-cylindrical magnets 521, and the two magnets 521 are spliced to form the second magnetic member 52 in a cylindrical shape, and opposite magnetic poles of the two magnets 521 are oriented in the same direction, that is, N and S poles of the two magnets 521 are located on the same end face of the second magnetic member 52. Also, when the display body 200 is in the installation posture, that is, the horizontal posture and is directed to the attachment device 100, the N poles and the S poles of the two magnets of the second magnetic member 52 located at the end surface are opposed to the S poles and the N poles of the two magnets of the first magnetic member 51 of the attachment device 100, so that when the operator holds the display body 200 with his hand to make the insertion hole 202 opposed to the attachment device 100 and approach the attachment device 100, the head of the telescopic sleeve 30 of the attachment device 100 is inserted into the insertion hole 202, as shown in fig. 5, the second magnetic member 52 attracts the first magnetic member 51 and finally inserts the telescopic sleeve 30 of the attachment device 100 into the insertion hole 202 by the attractive force and combines the display body 200 with the attachment device 100 by the magnetic attractive force, thereby completing the installation. Preferably, a ramp is provided at the port of the receptacle 202, which facilitates the attachment device 100 being able to be inserted into the receptacle 202 without having to be perfectly centered. As can be seen, the display body 200 and the attachment device 100 are attached by magnetic coupling, thereby reducing the difficulty in mounting the display body 200.

The above-mentioned attaching device 100 is further advantageous in that when the display body 200 needs to be detached from the attaching device 100, specifically, as shown in fig. 7, the operator applies force to the display body 200 in the direction of the wall by both hands, so that the display body 200 presses the telescopic sleeve 30 of the attaching device 100, the telescopic sleeve 30 retracts after being pressed, the first magnetic member 51 is driven to twist along with the rotating sleeve 40 by the transmission mechanism 60, in the process that the twisting angle of the first magnetic member 51 is from less than 90 ° to more than 90 °, as shown in fig. 3 and 4, the magnetic poles of the two magnets of the first magnetic member 51 and the magnetic poles of the two magnets of the second magnetic member 52 are misaligned, so that the first magnetic member 51 and the second magnetic member 52 are switched from the magnetic attraction force to the magnetic repulsion force, and when the first magnetic member 51 and the second magnetic member 52 are twisted to the final twisting angle, at this time, the operator applies force in the direction away from the wall 300, so that the display body 200 is detached from the attaching device 100.

In some preferred embodiments, the inner hole wall of the head of the telescopic sleeve 30 is provided with a first friction section 911, the outer circumference of the rotating sleeve 40 is provided with a second friction section 912 at an axial position corresponding to the first friction section 911, and the second friction section 912 is matched with the first friction section 911 after the twisting angle exceeds 90 ° during the twisting process of the rotating sleeve 40. Thus, as shown in fig. 4, in the process of detaching the display body 200, when the telescopic sleeve 30 is compressed to retract so that the rotating table is twisted to the final twisting angle and the display body 200 is far away from the attachment device 100, the friction force between the first friction section 911 and the second friction section 912 causes the rotating sleeve 40 to be slowly twisted and reset, thereby preventing the second magnetic member 52 of the display body 200 from being attracted again after the rotating sleeve 40 is quickly reset.
