[0042] Specifically, Figure 4As shown, when the display 4 is fixedly installed on the telescopic support frame 3, the height of the display 4 is first adapted by adjusting the length of the first telescopic pull rod 52, and the threaded rods 522 at both ends are driven to rotate by rotating the rotating nut 523. Since the thread directions of the two threaded rods 522 are opposite, the two threads are moved forward or backward to change the length. At this time, the two top and bottom slots 513, the right slot 511, the two connecting rods 512 and the first telescopic pull rod 52 form a stable and solid triangular support structure. After the display 4 is inserted in the horizontal direction, the length of the first telescopic pull rod 52 is continuously changed so that the two top and bottom slots 513 clamp the display 4 vertically, and then, the left slot 515 is fixed to the display 4. The left side of the display 4 is clamped, and then the mounting hook 54 at one end of the first telescopic rod 52 is hung with the two threaded rods 522 of the first telescopic rod 52, and the rotating nut 523 of the second telescopic rod 53 is rotated to change the length of the second telescopic rod 53, so that the two sides of the display 4 are clamped by the left clamping slot 515 and the right clamping slot 511. At this point, the display 4 is fixedly installed. In addition, in order to prevent the display 4 from being damaged by excessive rigid stress during the clamping process, shock-absorbing pads 514 are arranged in all the clamping slots. The deformation of the shock-absorbing pads 514 buffers the clamping stress, and also buffers the vibration of the display 4, thereby effectively protecting the movement of the display 4 and effectively reducing the probability of accidental damage during transportation or outdoor use.

[0043] In a preferred embodiment of the utility model, further, the shock-absorbing stand 56 includes a fixed plate 564, the two ends of the bottom of the fixed plate 564 are respectively fixedly connected to the tops of the two support rods 565, the bottoms of the two support rods 565 are fixedly connected to the top of the flip plate 567, one side of the flip plate 567 is hinged to one side of the slider 552, and the top center of the flip plate 567 is movably connected with a fixed handle 568, the fixed handle 568 is threadedly connected to the top of the slider 552, the rotating sleeve 516 is sleeved on the outside of the support rod 565, and a rotating positioning device is arranged between the two rotating sleeves 516.

[0044] In a preferred embodiment of the utility model, further, the rotation positioning device includes two directional gears 562, the directional gears 562 are fixedly connected to the middle part of the rotating sleeve 516, a double-headed spring pin 563 is arranged between the two directional gears 562, the two pin shafts of the double-headed spring pin 563 are respectively engaged with the two directional gears 562, the double-headed spring pin 563 is fixedly connected to the baffle 566 through a rod, the baffle 566 is fixedly connected between the two support rods 565 and is located below the rotating sleeve 516, a buffer spring 561 is arranged between the bottom of the fixed plate 564 and the top of the rotating sleeve 516, and between the bottom of the rotating sleeve 516 and the top of the baffle 566, and the buffer spring 561 is sleeved on the outside of the support rod 565.

[0045] Specifically, Figure 5 As shown, in order to facilitate storage and display after the bidding project is completed, the folding shock-absorbing frame 5 is designed to be foldable, and a flip plate 567 is provided at the bottom of the two support rods 565 of the shock-absorbing stand 56, and the flip plate 567 is hinged to the slider 552 at the bottom thereof, so that it can be flipped 180 degrees, so that the folding shock-absorbing frame 5 together with the display 4 can be flipped as a whole into the storage area of ​​the storage box 13, thereby realizing the storage function of the electronic device, and by providing a shock-absorbing pad 514 outside each card slot, the shock-absorbing pad 514 contacts the bottom of the inner wall of the storage area and the bottom of the storage cover 12, thereby preventing the bidding device from causing collision and damage to the display 4 during transportation;

[0046] During use, in order to prevent accidental movement, collision, and vibration of the device from causing damage to the display 4, the clamping frame 51 is sleeved on the outside of the support rod 565 by the rotating sleeve 516 provided in the right card slot 511, and buffer springs 561 are provided at the top and bottom of the rotating sleeve 516. The buffer springs 561 are supported as reaction forces by the fixing plate 564 and the baffle plate 566, so that when the display 4 vibrates together inside the clamping frame 51, the buffer springs 561 can effectively reduce shock, thereby effectively protecting the normal operation of the display 4;

[0047] Secondly, in order to enable the clamping frame 51 to be used for clamping and fixing installation of various types of monitors 4, a right card slot 511 is provided, and two top and bottom card slots 513 are respectively hingedly connected by two connecting rods 512. The two top and bottom card slots 513 are symmetrically arranged and connected by a first telescopic pull rod 52. By rotating the rotating nut 523 of the first telescopic pull rod 52, the two threaded rods 522 with opposite threads are driven to rotate, thereby driving the two threaded cylinders 521 to move together or away from each other synchronously, thereby changing the spacing between the two top and bottom card slots 513, so as to adapt to the height adjustment of monitors 4 of different sizes. After the adjustment is completed, The right card slot 511 and the two top and bottom card slots 513 cooperate with the two connecting rods 512 and the first telescopic rod 52 to form a stable triangular structure, so that the display 4 can be inserted horizontally from the left side. Subsequently, the left card slot 515 is connected to the left side of the display 4 and the mounting hook 54 at one end of the second telescopic rod 53 is connected to the first telescopic rod 52, and then the second telescopic rod 53 is retracted to lock and fix the left card slot 515. Thus, the installation and fixation of the entire display 4 is completed. The overall structure is simple, the operation is convenient and reliable, and it can be applied to a variety of different display 4 sizes, thereby increasing the work efficiency and the versatility of the device.

[0048] Thirdly, in order to facilitate bidders to clearly see the contents displayed on the display 4 when they are seated separately, a directional gear 562 is set in the middle of the aligning sleeve, and a bolt spring pin is connected to the top center of the baffle 566 through a rod. When the operator rotates the display 4 to adjust the viewing angle, the rotating shaft of the clamping frame 51 rotates around the support rod 565, thereby driving the directional gear 562 to rotate, thereby forcing the pin shaft of the double-headed spring pin 563 to be compressed and retracted into the outer sleeve. When the angle adjustment stops, the pin shaft of the double-headed spring pin 563 is re-inserted into the slot of the directional gear 562 and positioned by the resistance applied by the double-headed spring pin 563, so that the display 4 has the function of adjusting the viewing angle over a wide range, so that bidders and staff scattered at various positions of the device can clearly observe the display 4 and make correct responses, thereby effectively ensuring the smooth progress of the bidding work.
