It should be noted that, the damping slot 251 may also be a damping hole, and when the handle 21 is located at the lower end of the sliding stroke, in order to better match the installation space of the display screen device, so that the handle 21 has different angle settings, it is preferable that the damping slot 251 is radially distributed around the rotating shaft 23 in plural numbers to better meet different requirements of users. More preferably, the plurality of damping grooves 251 are symmetrically arranged about the axis of the rotating shaft 23, and two damping protrusions 252 are symmetrically arranged about the axis of the rotating shaft 23, so that the damping protrusions 252 and the damping grooves 251 can be better matched, and the damping force is neither too large nor too small, so as to facilitate the adjustment of each position of the handle 21; in addition, the symmetrical structure makes the damping force applied to the handle 21 more uniform, thereby improving the damping effect. Further, referring to fig. 4, the damping groove 251 and the damping protrusion 252 are both strip-shaped and extend along the radial direction of the rotating shaft 23 to better ensure the damping effect and prevent the handle 21 from rotating freely. Preferably, the depth of the damping groove 251 and the height of the damping protrusion 252 are smaller than the limiting concave part 242 and the limiting protrusion 241, considering that the insertion fit of the limiting protrusion 241 and the limiting concave part 242 is a force applied when the display screen device is carried, so the fit strength is higher, and the fit of the damping groove 251 and the damping protrusion 252 is more to prevent the handle 21 from rotating randomly, so as to prevent the handle 21 from hitting the rear cover of the device body 1 due to random shaking and damaging the rear cover of the device body 1 or the plug-in external device and the connection harness of the connection port, so a smaller blocking force can be provided, and therefore, the depth of the damping groove 251 and the height of the damping protrusion 252 are smaller to ensure the length of the sliding stroke of the handle 21, and better ensure the normal use of the handle assembly 2.

In a preferred embodiment, referring to fig. 1-4, the mounting seat 22 is provided with a mounting hole 223, the handle 21 is inserted into the mounting hole 223 through the rotating shaft 23, the mounting hole 223 may be a through hole or a blind hole, when the mounting hole 223 is a through hole, the insertion of the rotating shaft 23 is more convenient, and the resistance during the insertion is relatively small. When the mounting hole 223 is a blind hole, when the rotating shaft 23 is inserted, the original gas in the blind hole can block the insertion of the rotating shaft 23, at this time, the inner wall of the mounting hole 223 is preferably provided with the vent groove 224, and the vent groove 224 penetrates through the end surface of the mounting hole 223, so that the rotating shaft 23 can be inserted more conveniently. Of course, in order to facilitate the insertion of the shaft 23 into the mounting hole 223, the mounting hole 223 may be a through hole, and the vent groove 224 may be provided so as to penetrate the entire through hole. In addition, the blind hole can make the outward appearance of mount pad more pleasing to the eye to a certain extent, and whole harmony is better.

In order to avoid the random sliding of the handle 21 in the vertical direction and facilitate the sliding of the operating handle 21 in the sliding stroke, the rotating shaft 23 and the handle 21 are preferably of an integral structure, or the rotating shaft 23 and the handle 21 are in interference fit, the rotating shaft 23 and the mounting hole 223 are in clearance fit, and the fit clearance is +0.03mm to +0.08mm, so that a certain friction force exists between the rotating shaft 23 and the mounting seat 22 with the mounting hole 223 to reduce or eliminate the free falling of the handle 21 due to gravity, and the good fit of the handle 21 and the mounting seat 22 is ensured. Specifically, referring to fig. 2 and 3, the rotating shaft 23 is in an interference fit with the handle 21, that is, a connecting hole 213, preferably a through hole, for installing the rotating shaft 23 is provided on the connecting portion 212 of the handle 21, so as to facilitate the installation of the rotating shaft 23. For example, the diameter of the portion of the rotating shaft 23 that fits the mounting hole 2223 is smaller, and the diameter of the portion that fits the handle 21 is larger, so that when the rotating shaft is mounted, the smaller end of the rotating shaft passes through the connecting hole 213 on the handle 21 and is inserted into the mounting hole 223 on the mounting seat 22, and the larger portion of the rotating shaft 23 is inserted into the connecting hole 213 and is in interference fit with the connecting hole 213, so that the rotating shaft 23 is tightly connected with the handle 21, and the rotating connection between the handle 21 and the mounting seat 22 is realized. In the above case, the mounting seat 22 can be integrally or separately configured (i.e., including the first mounting portion 221 and the second mounting portion 222 which are separate), thereby ensuring smooth assembly of the handle assembly 2 and ensuring feasibility of the solution. Of course, when the mounting seat 22 is a split structure, the rotating shaft 23 may be assembled with the handle 21, then assembled with the mounting seat 22, and finally the mounting seat 22 is fixed to the device main body 1, at this time, the rotating shaft 23 may be a cylindrical structure with the same diameter of each portion, and the aperture of the connecting hole 213 is slightly smaller than that of the mounting hole 223, so as to ensure that the rotating shaft 23 is in interference fit with the connecting hole 213 and in clearance fit with the mounting hole 223. The rotation shaft 23 may be in clearance fit with the connection hole 213 and in interference fit with the mounting hole 223, and the handle 21 may be rotatably connected to the mounting seat 22.

Preferably, the edge of the damping groove 251 along the circumferential direction of the rotating shaft 23 has a guiding surface (not shown in the figure), when the fixed angle of the handle 21 needs to be adjusted, the guiding surface is arranged to reduce the friction between the damping protrusion 252 and the damping groove 251, so as to reduce the friction damage, preferably, the guiding surface is an arc-shaped surface, so that the appearance is smooth, the friction between the damping groove 251 and the damping protrusion 252 is further reduced, and correspondingly, the guiding surface can also be arranged on the damping protrusion 252, so as to further reduce the friction between the damping groove 251 and the damping protrusion.
