There is a through operation hole 91, and the operation part 62 continues to pass through the through operation hole 91 (certainly the operation hole 91 should also leave the necessary movement stroke of the operation part 62 at least in the up and down direction. space) and exposed (exposed to facilitate hand operation) , so as to move the operation part 62 up and down by hand operation; the middle part of the plastic rear cover 90 is provided with a through connection hole 92 .

Further, the orientation chute 64 has a concave stepped surface 65 surrounding the notch at the front 11 (as shown in FIG. 1 ) ; the limiting pin 70 is T-shaped (as shown in FIG. 1 ) , and the upper end is a head Part 71 forms a stopper, and the top surface of the head 71 is provided with a groove to facilitate locking with a tool, and the end of the lower part is provided with an external thread 72 (two screw holes should be established on the corresponding main connecting plate body 10 at this time, for screw lock) , the upper end of the external thread 72 has a circular section stop step surface and extends upward from the step surface to form a shaft part 73, when tightening, the stop step surface presses the front surface 11 and locks fixed on the main connecting plate body 10 (this is a well-known locking technology, so it will not be described in detail) , the shaft part 73 is fitted in the directional chute 64 to further constrain the sliding plate body 61 It can slide up and down, and the head 71 is close to (that is, not completely pressed, so as to slide) the concave step surface 65 to form a stop , preventing the sliding plate body 61 from breaking away from the front surface 11 ( while also hiding the head role of Section 71) .

Further, the top of the display support frame is fixedly connected to the main connecting plate body 10 through the connecting hole 92 (this is a well-known technology in this industry, so it will not be described in detail) .

Further, the maximum movable distance value of the operation part 62 up and down in the through hole 30 and the operation hole 91, and the maximum vertical distance value of the limit pin 70 in the orientation chute 64 and The seat block abuts against the compression spring 80 in the accommodating groove 50 by the maximum moving distance value up and down, and the minimum distance value among the four is compared to define the up and down movement stroke of the operating part 62 (this is obvious ; the upper limit position must at least ensure that the lower claw 63 is disengaged from the lower connection notch of the display, and the lower limit position must at least ensure that the lower claw 63 is inserted into the lower connection notch of the display) .

During specific operation, because the display back is provided with connection notches up and down, it is obvious that as long as the hand moves up or down, the operating part 62 can be moved to quickly disengage the lower claw 63 (this time, of course, to overcome the above-mentioned The compressed elastic force of the compression spring 80, obviously the spring force can be used to prevent the lower claw 63 from automatically disengaging from the lower connection notch of the display when the assembled complete machine works normally) or elastically inserted into the lower connection notch of the display, thereby Realize quick assembly and disassembly (of course, the upper claws 20 should be coordinated together and connected to or separated from the upper connection notch of the display).

The utility model overcomes the defects of the prior art, can realize the quick disassembly and assembly of the display and the top connector of the support frame without tools, reduces the packaging volume, saves transportation costs, and has the advantages of simple structure, easy manufacture, and low cost. Low, easy to use, no tools, flexible operation, quick disassembly and assembly. In addition, from the point of view of the specific structure, the covering part structure is especially adopted, which realizes the upper and lower directional limit function of the plastic sliding plate body only by stamping incidentally, even without relying on the limit pin Or reduce the use of its number, the structure is particularly simple, easy to realize reliable, low cost; in addition, the positioning structure of the compression spring is also very simple and reliable.
