The clamp 202 is disposed opposite to the mounting base 201. One end of the mounting base 201 is hinged to one end of the clamp 202 through the first screw 203, and the other end of the mounting base 201 is hinged to the locking screw 205 through the second screw 204. By screwing the locking nut 206 onto the locking screw 205, the other end of the clamp 202 is tightly connected to the other end of the mounting base 201, and a clamping space is formed between the clamp 202 and the mounting base 201.

[0030] More specifically, as Figures 5 to 7 shown, two rows of screw holes 207 are provided on the back surface of the mounting base 201, and a positioning groove 208 is provided between the two rows of screw holes 207. The front surface of the mounting base 201 is a semi-circular concave surface, and a set of corresponding threaded holes 209 and through holes 210 are provided at both end portions of the semi-circular concave surface, i.e., both end portions of the mounting base 201.

[0031] As Figures 8 to 10 shown, the clamp 202 is in a semi-circular ring shape. Limiting ridges 211 are provided on the inner side surface opposite to the front surface of the mounting base 201 and on the semi-circular concave surface of the mounting base 201 and correspond to each other. The limiting ridges 211 are matched with the limiting grooves 102 on the mounting portion 101. One end of the clamp 202 is provided with a connecting hole 212, the other end is provided with a mounting ear, and a U-shaped opening 213 is provided on the mounting ear.

[0032] Referring to Figure 2 and Figure 11 , the head of the locking screw 205 is provided with a perforation, the end face of the threading-in portion of the locking screw 205 is provided with an internal threaded hole, and a limiting screw 5 is screwed into the internal threaded hole. The internal threaded hole of the locking nut 206 is a blind hole. By controlling the depth of the limiting screw 5 screwed in, the depth of the locking nut 206 screwed into the thread portion of the locking screw 205 can be limited and controlled.

The upper side connection holes correspond to the two rows of screw holes 207, and a positioning ridge 301 matched with the positioning groove 208 is further provided on the adapter plate 3.

[0034] When installing and using, after placing the clamp 202 and the mounting base 201 in opposite positions, embed one end of the clamp 202 into the corresponding end of the mounting base 201, so that the threaded hole 209, the connecting hole 212 and the through hole 210 correspond to each other. Then, sequentially pass the first screw 203 through the through hole 210, the connecting hole 212 and the threaded hole 209 on this end side. At this time, the clamp 202 and the mounting base 201 form a hinge mechanism that can rotate around the first screw 203. Then, embed the locking screw 205 into the other end of the mounting base 201, so that the threaded hole 209, the through hole and the through hole 210 at this end correspond to each other. Then, sequentially pass the second screw 204 through the through hole 210, the through hole and the threaded hole 209 on this end side. At this time, the locking screw 205 and the mounting base 201 form a hinge mechanism that can rotate around the second screw 204. Then, select a section of the limiting groove 102 on the mounting part 101 of the fixed base 1 according to needs. Then, embed the limiting rib 211 of the mounting base 201 into the limiting groove 102. Then, bring the mounting ear of the clamp 202 close to the other end of the mounting base 201. The locking screw 205 rotates around the second screw 204 and enters the U-shaped opening 213. At the same time, adjust the depth of the limiting screw 5 in the locking screw 205. Finally, screw the locking nut 206 onto the locking screw 205 to press the clamp 202 and the mounting base 201, so that the hoop assembly 2 is rotatably installed on the fixed base 1. Subsequently, the adapter plate 3 can be positioned and installed on the mounting base 201 by screws, and then the display screen 4 can be installed on the lower side of the adapter plate 3 by screws through its threaded interface.

[0035] In summary, the multiple sections of limiting grooves 102 provided on the fixed base in the present utility model can adjust the height of the mounting base 201 of the hoop assembly 2 according to the situation inside the vehicle, avoiding affecting the operation of personnel; a limiting screw 5 is provided at the locking screw 205 for limiting, so that the hoop assembly 2 can be rotatably adjusted on the mounting base 201, which not only plays a role in limiting but also facilitates the installer to judge the depth of screwing in of the locking nut 206, preventing damage caused by over-tightening; the overall structure adopts a hoop structure, and only the combination of the locking screw 205 and the locking nut 206 is required at the connection where the hoop is opened and closed, so as to achieve rapid disassembly and adjustment to meet the use of different drivers.
