[0028] Please refer to Figures 1-5, the present utility model provides a technical solution: a positioning device for repairing ancient building railings, including a first clamping plate 1 and a second clamping plate 2 arranged on the opposite side of the first clamping plate 1; among them, the process of repairing the railing has been mentioned in the prior art and will not be elaborated here. One side of the second clamping plate 2 is provided with an adjusting component 4, and the adjusting component 4 includes a connecting plate 401. A rotating column 402 is rotatably connected inside the connecting plate 401, and a rotating block 403 is fixedly connected to the bottom of the rotating column 402; among them, a gear 404 is fixedly connected to the top of the rotating block 403, and limiting blocks 405 are symmetrically fixed to the top of the connecting plate 401. A rack 406 is slidably connected inside the limiting blocks 405, and the gear 404 is meshed with the rack 406;

[0029] Among them, a chute 407 is opened inside the second clamping plate 2, a limiting rod 408 is fixedly connected inside the chute 407, and a sliding rod 409 is slidably connected to the outside of the limiting rod 408. As Figure 2 , 5 shown, rotate the rotating block 403, so that the rotating block 403 drives the rotating column 402 to rotate, then the rotating column 402 will drive the gear 404 to rotate, and then the gear 404 will drive the racks 406 on both sides to move simultaneously, and the positions of the racks 406 on both sides move towards each other, and then the racks 406 on both sides will drive the sliding rods 409 on both sides to move towards each other.

[0030] One side of the sliding rod 409 is fixedly connected to the rack 406, and a moving block 410 is fixedly connected to the side of the sliding rod 409 away from the rack 406. Sliding blocks 411 are symmetrically slid inside the first clamping plate 1, and a threaded rod 412 is rotatably connected inside the sliding blocks 411. The threaded rod 412 passes through the bottom of the sliding block 411 and is threadedly connected to the moving block 410. A fixed column 413 is fixedly connected to the top of the gear 404, and a rotating rod 414 is fixedly connected to the top of the fixed column 413. A limiting strip 415 is fixedly connected to the top of the second clamping plate 2, and a moving plate 4151 is slidably connected to the top of the limiting strip 415. The moving plate 4151 abuts against the rotating rod 414. A square block 416 is fixedly connected to the top of the limiting strip 415, and a first spring 417 is fixedly connected between the square block 416 and the moving plate 4151. One side of the moving plate 4151 is fixedly connected to a telescopic rod 418, and a second spring 419 is fixedly connected to one side of the moving plate 4151. The second spring 419 is located at the bottom of the telescopic rod 418, and a square plate 420 is fixedly connected to one side of the telescopic rod 418 and the second spring 419. As Figure 2 , 3, as shown in Figure 4, the racks 406 on both sides will drive the slide bars 409 on both sides to move towards each other at the same time. Then, the slide bars 409 on both sides will drive the moving blocks 410 on both sides to move. Cooperating with the threaded rod 412, the sliding block 411 will also move towards each other, so that the lateral distance of the rod can be adjusted. At the same time, the threaded rod 412 can be rotated, so that the threaded rod 412 drives the moving block 410 to move. Then, the moving block 410 will drive the second clamp plate 2 to move, so that the rod can be fixed. Secondly, while the gear 404 rotates, it will drive the fixed column 413 to rotate. Then, the fixed column 413 will drive the rotating rod 414 to rotate and press the moving plate 4151. At the same time, the moving plate 4151 will compress the first spring 417. Then, the moving plate 4151 will drive the telescopic tube and the second spring 419 to move, so that the square plate 420 will move. Then, the square plate 420 will abut against one side of the rod, so as to assist in fixing the rod.

[0031] A limiting component 5 is arranged on one side of the second clamp plate 2. The limiting component 5 includes a mounting plate 501.

One side of the clamping shell 505 is fixedly connected with a control handle 506. As Figure 5 shown, the control handle 506 can be pulled downwards. Then, the control handle 506 will drive the clamping shell 505 to move downwards, so that the clamping shell 505 releases the limit on the rotating block 403, so that the rotating block 403 can rotate. While the clamping shell 505 moves, it will compress the third spring 503. When it is necessary to re-limit the rotating block 403, only need to release the control handle 506, and the third spring 503 will bounce back.

[0032] Working principle: Before using the electrostatic-removable plastic packaging film shearing machine, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown, first, when the railing needs to be repaired, first rotate the rotating block 403, so that the rotating block 403 drives the rotating column 402 to rotate. Then the rotating column 402 drives the gear 404 to rotate. Then the gear 404 drives the racks 406 on both sides to move simultaneously, and the positions of the racks 406 on both sides move towards each other. Then the racks 406 on both sides drive the sliding rods 409 on both sides to move towards each other. Then the sliding rods 409 on both sides drive the moving blocks 410 on both sides to move. Cooperating with the threaded rod 412, the sliding block 411 also moves towards each other, so that the lateral distance of the pole can be adjusted. At the same time, the threaded rod 412 can be rotated, so that the threaded rod 412 drives the moving block 410 to move. Then the moving block 410 drives the second clamp plate 2 to move, so that the pole can be fixed. Secondly, when the gear 404 rotates, it drives the fixed column 413 to rotate. Then the fixed column 413 drives the rotating rod 414 to rotate and press the moving plate 4151. At the same time, the moving plate 4151 compresses the first spring 417. Then the moving plate 4151 drives the telescopic tube and the second spring 419 to move, and further makes the square plate 420 move. Then the square plate 420 abuts against one side of the pole, so as to assist in fixing the pole;

[0033] The control handle 506 can be pulled downward. Then the control handle 506 drives the cartridge case 505 to move downward, so that the cartridge case 505 releases the limit on the rotating block 403, so that the rotating block 403 can rotate. At the same time when the cartridge case 505 moves, the third spring 503 is compressed. When the rotating block 403 needs to be re-limited, just release the control handle 506, and the third spring 503 will bounce back.
