The problem of ageing of a flexible conduit and the problem of suitably matching the storage position of an external placed box after the use of the multi-linkage device are solved by using the multi-linkage device and by folding multiple linkages. In addition, the cooperation of the coarse and fine adjustments of the display device is achieved by the connection relationship between the various linkages and a user can quickly and conveniently adjust the display device to be at any angle by the structure. With an adjustment mechanism with a damping or post-adjustment locking mechanism, the display device can be positioned in an adjustment position convenient for viewing. ## Claims ### Claim 1 A display device with adjustable viewing angle, comprising a base portion, one end of a multi-link mechanism is disposed on the base portion, and the other end is disposed with a display device. ### Claim 2 (depends on 1) The display device with adjustable viewing angle according to claim 1, wherein a first adjusting device is disposed between the multi-link mechanism and the base portion. ### Claim 3 (depends on 2) The display device with adjustable viewing angle according to claim 2, wherein a second adjusting device is disposed between the display module and the multi-link mechanism. ### Claim 4 (depends on 3) The display device with adjustable viewing angle according to claim 3, wherein the multi-link mechanism comprises a head link and a tail link, one end of the head link is disposed on the base portion by a first adjusting device, and the other end of the head link is movably connected to one end of the tail link, and the other end of the tail link is provided with the display device by a second adjusting device. ### Claim 5 (depends on 4) The display device with adjustable viewing angle according to claim 4, wherein the other end of the first adjusting device or the head link is connected to one end of the tail link by a hinge structure. ### Claim 6 (depends on 3) The display device with adjustable viewing angle according to claim 3, wherein the second adjusting device adopts a ball shaft structure. ### Claim 7 (depends on 6) The display device with adjustable viewing angle according to claim 6, wherein the ball shaft structure is a universal ball shaft structure. ### Claim 8 (depends on 4) The display device with adjustable viewing angle according to claim 4, wherein the head link is connected with the tail link through a link or a link group. ### Claim 9 (depends on 1) The display device with adjustable viewing angle according to claim 1, wherein a control button is disposed at the multi-link mechanism or at the display device. ### Claim 10 (depends on 3) The display device with adjustable viewing angle according to claim 3, wherein the device further comprises a thermal imager, and the base portion is disposed at the thermal imager. ### Claim 11 (depends on 3) The display device with adjustable viewing angle according to claim 3, wherein the device further comprises a spectacle frame, and the base portion is disposed at the spectacle frame. ### Claim 12 (depends on 3) The display device with adjustable viewing angle according to claim 3, wherein the base portion is provided with a snapping port. ### Claim 13 (depends on 10) The display device with adjustable viewing angle according to claim 10, wherein the base portion is connected to the thermal imager or the spectrum frame through a snap structure. ### Claim 14 (depends on 3) The display device with adjustable viewing angle according to claim 3, wherein the device further comprises an accommodating unit, and the base portion is disposed in the accommodating unit. ### Claim 15 (depends on 14) The display device with adjustable viewing angle according to claim 14, wherein the accommodating unit comprises an accommodating box, a baffle assembly disposed in the accommodating box, the baffle assembly comprises a top bead spring and a latching top bead disposed at the top of the top bead spring, and the multi-link mechanism cooperated therewith is provided with a card slot, and when accommodating, the latching top bead is snapped into the card slot. ### Claim 16 (depends on 15) The display device with adjustable viewing angle according to claim 15, wherein the accommodating unit further comprises a dialing component disposed on one side of the accommodating box, the dialing component comprises a dialing hand, a recovering spring, and a thimble, and the accommodating box is provided with a hole through which the thimble can pass, when dialing the dialing hand, the thimble passes through the hole of the accommodating box and then withstands the multi-link mechanism, so that the multi-link mechanism overcomes the elastic force of the latching top bead and then slides the latching top bead out of the card slot; after releasing the dialing hand, the recovering spring returns the dialing hand. ### Claim 17 (depends on 4) The display device with adjustable viewing angle according to claim 4, wherein a friction layer is provided on the surface of the tail link. ### Claim 18 (depends on 14) The display device with adjustable viewing angle according to claim 14, wherein a buffering component is disposed inside the accommodating unit. ### Claim 19 (depends on 4) The display device with adjustable viewing angle according to claim 4, wherein the device further comprises an accommodating groove, and the multi-link mechanism is accommodated in the accommodating groove. ### Claim 20 (depends on 14) The display device with adjustable viewing angle according to claim 14, wherein the accommodating unit is provided with a snap structure.
