[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 fixing splint 52 is slidably sleeved on the four limiting guide rods 51, and the fixing splint 52 is slidably sleeved on the transverse guide rod 11. The top and bottom ends of the fixing splint 52 are provided with a limiting sink groove 517, and the transverse guide rod 11 is slidably clamped in the limiting sink groove 517. The setting and use of the limiting sink groove 517 ensure the normal sliding of the fixing splint 52, and the fixing splint 52 can fit tightly with the blind plate body 4.

[0027] By adopting the above technical solution, when in use, the operating rocker 516 is rotated, thereby driving the operating hand wheel 515 to rotate, and then driving the stud 59 to rotate, and further driving the two lifting horizontal plates 58 to do back movement, 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 can cooperate with the limiting guide rod 51 Use the method to drive the fixed splint 52 to move stably and steadily toward the side close to the head plate body 2, so that the fixed splint 52 can contact with the blind plate body 4 and push the blind plate body 4 to move, and then the head plate body 2 can be tightly 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 splint 52 can be tightly fitted to each other. During this period, the staff needs to synchronously observe whether the plate has any misalignment and whether the rubber pad has any protrusion, until the distance between the fixed splint 52 and the frame body 1 close to the head plate body 2 is moved to the calculated value.

[0028] The prompt mechanism 6 includes a mounting cover 61 and a first touch rod 62. The mounting cover 61 is fixedly mounted on the fixed splint 52, and the mounting cover 61 has a symmetrical structure.

A first spring 64 is fixedly connected to the inner wall of the mounting cover 61, and a sliding snap ring 65 is fixedly connected to the end of the first spring 64. The sliding snap ring 65 is slidably plugged into the inner cavity of the mounting cover 61, and the middle part of the sliding snap ring 65 is fixedly inserted into the driven push rod 66. A symmetrically arranged sliding through hole 12 is opened on the fixed splint 52, and the driven push rod 66 slides through The sliding through hole 12 is passed through, and the sliding clamp 65 is penetrated by an array of mounting through holes 67, and the second touch rod 68 is fixedly inserted in the mounting through hole 67, and the fixed splint 52 is provided with symmetrically distributed mounting countersunk holes 13 on the side close to the second touch rod 68. The first touch rod 62 is fixedly inserted in the mounting countersunk hole 13, and the first touch rod 62 and the second touch rod 68 can be in close contact. When the first touch rod 62 and the second touch rod 68 are in contact, the power of the prompt lamp body 63 will be turned on and lit, and when the first touch rod 62 and the second touch rod 68 are separated, the prompt lamp body 63 will be powered off and extinguished. This circuit principle is existing technology and will not be described in detail here.

[0029] By adopting the above technical solution, when in use, if the blind plate body 4 is not omitted to be installed, the movement of the driven push rod 66 will be restricted when the fixed splint 52 contacts and tightens 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 prompt light body 63 will move synchronously with the fixed splint 52, thereby enabling the first touch rod 62 and the second touch rod 68 to separate and squeeze the first spring 64, further enabling the prompt light body 63 to be powered off and extinguished. If the blind plate body 4 is omitted to be installed, the movement of the driven push rod 66 will not be restricted during the movement of the fixed splint 52. At this time, the prompt light body 63 will be in a long-light state, thereby reminding the staff that the blind plate body 4 is omitted to be installed.

[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 a symmetrical structure. A limiting slide bar 74 is slidably inserted on the L-shaped mounting plate 71, and one end of the limiting slide bar 74 is fixedly sleeved with a limiting collar 75, and an operating handle 78 is fixedly connected to the limiting collar 75, and the outer wall of the operating handle 78 is covered with a layer of anti-slip grooves. The setting and use of the operating handle 78 provides convenience for the convenient movement of the limiting collar 75. A second spring 76 is fixedly mounted on one side of the limiting collar 75, and the second spring 76 is fixedly mounted on the second side of the limiting collar 75.

The side of the frame body 1 close to the storage mechanism 8 is provided with a take-and-place groove for use with the measuring scale 72, thereby ensuring the normal take-and-place of the measuring scale 72. This is a prior art and will not be described in detail here. One end of the measuring scale 72 is penetrated by a limited slot 77, and the limit slide 74 can be slidably inserted. In the limiting socket 77, the U-shaped calibration rod 73 is fixedly mounted on both sides of the fixed splint 52, and the measuring scale 72 can slide and fit with the U-shaped calibration rod 73. The storage mechanism 8 includes a storage frame 81, which is fixedly mounted 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 into 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.

The return torsion spring 87 is movably sleeved on the rotating horizontal shaft 84, and the end of the return torsion spring 87 is fixedly connected to the storage frame 81. An operating groove 88 for use 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 groove 88 facilitates the rotation of the rotating pressure plate 85, and both sides of the storage frame 81 are provided with operating sinks 89 for use with the measuring scale 72. The setting and use of the operating sinks 89 facilitate the access to the measuring scale 72.

[0031] By adopting the above technical solution, when in use, the rotating pressure plate 85 is pushed to rotate, thereby twisting the two reset torsion springs 87, 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 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, thereby driving the corresponding limit ring 75 to move, and then driving the corresponding limit slide 74 to move and stretch the corresponding second spring 76. When the limit ring 75 is aligned with the corresponding L-shaped mounting plate When the distance 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, 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 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 push it toward 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 second spring 76 will drive the corresponding limiting collar 75 to return to its original position, thereby driving the corresponding limiting slide bar 74 to return to its original position and inserting it 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 horizontal plates 58 are further driven to move backwards, so that the first T-shaped block 53 and the first U-shaped block 54, the second T-shaped block 57 and the second U-shaped block 56, the third T-shaped block 510 and the third U-shaped block 511, and the fourth U-shaped block 513 and the fourth T-shaped block 514 can be used to drive the first rotating plate 55 and the second rotating plate 512 to rotate synchronously, and can cooperate with the use of the limiting guide rod 51 to drive the fixed splint 52 to move stably and smoothly toward the side close to the head plate body 2, so that the fixed splint 52 and the blind plate body can be aligned. The body 4 contacts and pushes the blind plate body 4 to move, thereby enabling the head plate body 2 to fit tightly on the frame body 1 and enabling the head plate body 2, the middle plate body 3, the blind plate body 4 and the fixed splint 52 to fit tightly 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 simultaneously observe whether the plate is misaligned and whether the rubber pad is protruding, until the distance between the fixed splint 52 and the side of the frame body 1 close to the head plate body 2 is moved to the calculated value, and then remove the used measuring scale 72 and insert it into the storage frame 81 again;

[0035] At the same time, if the blind plate body 4 is not omitted to be installed, 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 prompt light body 63 will move synchronously with the fixed splint 52, thereby enabling the first touch rod 62 and the second touch rod 68 to separate and squeeze the first spring 64, further enabling the prompt light body 63 to be powered off and extinguished. If the blind plate body 4 is omitted to be installed, the movement of the driven push rod 66 will not be restricted during the movement of the fixed splint 52. At this time, the prompt light body 63 will be in a long-light state, thereby reminding the staff that the blind plate body 4 is omitted to be installed.

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