[0026] The fixing mechanism 5 includes a limiting guide rod 51, which is fixedly inserted at the four corners of the frame body 1, and a fixed clamping plate 52 is slidably sleeved on the four limiting guide rods 51, and the fixed clamping plate 52 is slidably sleeved on the transverse guide rod 11. The top and bottom ends of the fixed clamping plate 52 are provided with limiting recessed grooves 517, and the transverse guide rod 11 is slidably clamped in the limiting recessed grooves 517.

At this time, the installation cover 61, the first touch rod 62 and the warning light body 63 will move synchronously with the fixed clamping plate 52, thereby enabling the first touch rod 62 to separate from the second touch rod 68 and squeeze the first spring 64, further enabling the warning light body 63 to be powered off and extinguished. If the blind plate body 4 is omitted from installation, the movement of the driven push rod 66 cannot be restricted during the movement of the fixed clamping plate 52. At this time, the warning light body 63 will be in a long-light state, thereby being able to remind the staff that the blind plate body 4 is omitted from installation.

[0030] The measuring mechanism 7 includes an L-shaped mounting plate 71, a measuring scale 72 and a U-shaped calibration rod 73. The L-shaped mounting plate 71 is fixedly mounted on the upper end of one side of the frame body 1, and the L-shaped mounting plate 71 is symmetrical in structure.

The storage mechanism 8 includes a storage frame 81, which is fixedly installed on the frame body 1, and the storage frame 81 is provided with symmetrically arranged storage slots 82, the measuring scale 72 can be slidably inserted in the storage slots 82, and the top of the storage frame 81 is penetrated by a mirror-distributed rotating through hole 83, a rotating horizontal axis 84 is rotatably inserted in the rotating through hole 83, and a rotating pressure plate 85 is rotatably sleeved on the rotating horizontal axis 84, and the rotating pressure plate Both ends of 85 are provided with mounting recessed holes 86, and a reset torsion spring 87 is fixedly installed on the inner wall of the mounting recessed hole 86. The reset torsion spring 87 is movably sleeved on the rotating horizontal axis 84, and the end of the reset torsion spring 87 is fixedly connected to the storage frame 81. An operating groove 88 used in conjunction with the rotating pressure plate 85 is provided in the middle of one side of the storage frame 81.

The setting and use of the operating recessed grooves 89 facilitate the use of the measuring scale 72.

[0031] By adopting the above technical solution, when in use, the rotating pressure plate 85 is pushed to rotate, so that the two reset torsion springs 87 can be twisted, and when the rotating pressure plate 85 is rotated ninety degrees, the rotating pressure plate 85 is stopped, the measuring scale 72 on the installation operation side is pulled out and the rotating pressure plate 85 is loosened, at this time, the reset torsion spring 87 will drive the rotating pressure plate 85 to reverse and reset, and then the operating handle 78 on the installation operation side is held and pulled, so that the corresponding limit ring 75 can be driven to move, and then the corresponding limit slide bar 74 can be driven to move and stretch the corresponding second spring 76. When the limit ring 75 is aligned with the corresponding L-shaped installation plate When the spacing between 71 moves to the maximum, stop pulling the corresponding operating handle 78 and insert the measuring scale 72 into the corresponding sliding slot 518 and the limit slot 14, and then release the corresponding operating handle 78. At this time, the second spring 76 will drive the corresponding limit ring 75 to reset, thereby driving the corresponding limit slide rod 74 to reset and insert it into the corresponding limit socket 77. During the fixing period, the staff can observe the corresponding position relationship between the U-shaped calibration rod 73 on the installation operation side and the measuring scale 72 while rotating the operating rocker 516, and remove and store the used measuring scale 72 after fixing.

[0032] Working principle: When in use, first install the battery of the warning light body 63, then clamp the head plate body 2 between the two transverse guide rods 11 and make it fit on the side of the frame body 1 close to the flange, then clamp the middle plate body 3 between the two transverse guide rods 11 and move it to the side close to the head plate body 2, and then clamp the blind plate body 4 between the two transverse guide rods 11;

[0033] The two return torsion springs 87 are then pushed to rotate the rotating pressure plate 85, and when the rotating pressure plate 85 is rotated ninety degrees, the rotating pressure plate 85 is stopped and the measuring scale 72 on the installation operation side is pulled out and the rotating pressure plate 85 is released. At this time, the return torsion spring 87 will drive the rotating pressure plate 85 to reverse and reset. Then, the operating handle 78 on the installation operation side is held and pulled, so that the corresponding limiting ring 75 can be driven to move, and then the corresponding limiting slide bar 74 can be driven to move and stretch the corresponding second spring 76. When the spacing between the limiting ring 75 and the corresponding L-shaped installation plate 71 moves to the maximum, the corresponding operating handle 78 is stopped and the measuring scale 72 is inserted into the corresponding sliding slot 518 and the limiting slot 14, and then the corresponding operating handle 78 is released. At this time, the second spring 76 will drive the corresponding limiting ring 75 to reset, so that the corresponding limiting slide bar 74 can be driven to reset and inserted into the corresponding limiting insertion hole 77.

[0034] Then, the operating rocker 516 is rotated to drive the operating hand wheel 515 to rotate, and then the stud 59 is driven to rotate, and the two lifting cross plates 58 are further driven to move backwards, so that the first T-block 53 and the first U-block 54, the second T-block 57 and the second U-block 56, the third T-block 510 and the third U-block 511, and the fourth U-block 513 and the fourth T-block 514 can be used to drive the first rotating plate 55 and the second rotating plate 512 to rotate synchronously, and the use of the limiting guide rod 51 can be used to drive the fixed clamping plate 52 to move stably and smoothly to the side close to the head plate body 2, so that the fixed clamping plate 52 and the blind plate body can be The blind plate body 4 contacts and pushes the blind plate body 4 to move, so that the head plate body 2 can be closely fitted on the frame body 1 and the head plate body 2, the middle plate body 3, the blind plate body 4 and the fixed clamping plate 52 can be closely fitted with each other. During this period, the staff can observe the corresponding position relationship between the U-shaped calibration rod 73 on the installation operation side and the measuring scale 72 while rotating the operating rocker 516, and it is necessary to simultaneously observe whether the plate is misaligned and whether the rubber pad is protruding, until the spacing between the fixed clamping plate 52 and the side of the frame body 1 close to the head plate body 2 is moved to the calculated value, and then the used measuring scale 72 is removed and inserted into the storage frame 81 again;

[0035] At the same time, if the blind plate body 4 is not omitted from installation, the movement of the driven push rod 66 will be restricted when the fixed splint 52 contacts and is tightened with the blind plate body 4, thereby restricting the movement of the sliding clamp 65 and the second touch rod 68. At this time, the installation cover 61, the first touch rod 62 and the warning light body 63 will move synchronously with the fixed splint 52, thereby enabling the first touch rod 62 to separate from the second touch rod 68 and squeeze the first spring 64, further enabling the warning light body 63 to be powered off and extinguished. If the blind plate body 4 is omitted from installation, the movement of the driven push rod 66 cannot be restricted during the movement of the fixed splint 52. At this time, the warning light body 63 will be in a long-light state, thereby being able to remind the staff that the blind plate body 4 is omitted from installation.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
