[0049] For example, Figure 7 、 Figure 8 and Figure 9As shown, the auxiliary protection assembly 5 includes a fifth fixing plate 501, one end of each group of the fifth fixing plates 501 is mounted on a side wall of one group of the clamping plates 405, a group of sleeve tubes 502 are mounted on the top of each group of the fifth fixing plates 501, a group of sliding tubes 503 are movably sleeved in each group of the sleeve tubes 502, a group of resistance plates 504 are mounted on the top of each group of the sliding tubes 503, one end of two groups of second compression springs 505 are symmetrically mounted on the top edge of each group of the fifth fixing plates 501, and the other end of each group of the second compression springs 505 is mounted on one group of the resistance plates 50 4, a group of third electric push rods 506 are installed on one side wall of each group of the fifth fixed plates 501, a group of first electromagnetic blocks 507 are installed on the output end of each group of the third electric push rods 506, a group of second electromagnetic blocks 508 are installed on one side wall of each group of the contact plates 504, the first electromagnetic blocks 507 are magnetically connected to the second electromagnetic blocks 508, a group of sixth fixed plates 509 are installed on one side wall of each group of the fifth fixed plates 501, a group of fifth motors 510 are installed on the top of each group of the sixth fixed plates 509, and a transmission connection is connected to the output end of each group of the fifth motors 510. A group of transmission plates 511 are installed on one side wall of each group of transmission plates 511, a group of fourth electric push rods 512 are installed on the output end of each group of fourth electric push rods 512, two groups of fourth electric push rods 514 are symmetrically installed on both side walls of each group of first connecting plates 513, a group of second connecting plates 515 are installed on the output end of each group of fourth electric push rods 514, a group of sleeve pipes 516 are installed on the top of each group of second connecting plates 515, and one end of a group of third compression springs 517 are installed on the bottom inner wall of each group of sleeve pipes 516. A group of sliding rods 518 are installed on the other end of the compression spring 517, and each group of the sliding rods 518 are slidably connected in the sleeve 516. A group of pressure sensors 519 are installed at the junction of each group of the sliding rods 518 and the third compression spring 517, and a group of pressure-resistant plates 520 are installed on the top of each group of the sliding rods 518. A group of sleeve rings 521 are sleeved on the outer wall of each group of the sliding rods 518, and a group of first distance sensors 522 are installed on the outer wall of each group of the sleeve rings 521. A group of second distance sensors 523 are installed on the corresponding side walls of the two groups of sleeve rings 521.

[0050] Before the door and window cutting device works, the first electric push rod 103 is first started to drive the second fixed plate 104 to move to the specified position, and then the clamping plate 405 is pushed to slide in the sliding groove 402 toward the fixed block 403. During the sliding process, the clamping plate 405 squeezes the first compression spring 404, and during the sliding process, the third electric push rod 506 is started to push the first electromagnetic block 507 and the second electromagnetic block 508 to be magnetically connected, and then the contact plate 504 is driven to move toward the fifth fixed plate 501. During the movement, the sliding tube 503 is driven to slide in the sleeve 502. The contact plate 504 begins to squeeze the second compression spring 505, and then the doors and windows that need to be cut are placed on the two sets of contact plates 504, and then the magnetic connection between the first electromagnetic block 507 and the second electromagnetic block 508 is separated. After the second compression spring 505 senses the disappearance of pressure, it begins to rebound, driving the contact plate 504 to squeeze the doors and windows, and then separates from the push on the clamping plate 405. After the first compression spring 404 senses the disappearance of pressure, it drives the clamping plate 405 to elastically limit the doors and windows, so that the clamping has a buffering effect, which improves the wrapping limiting effect while improving the convenience of disassembly and assembly.

[0051] Before cutting, the fourth electric push rod 514 is started to push the two sets of anti-pressure plates 520 to move to the bottom of the cutting structure 205 and avoid the output end range of the cutting structure. When the cutting structure 205 is cut, the fifth motor 510 is started to drive the transmission plate 511 to rotate. When the transmission plate 511 rotates, the two sets of anti-pressure plates 520 are always parallel to each other under the door and window. Then, during the translation movement of the cutting structure 205, the fourth electric push rod 512 is started to drive the anti-pressure plates 520 to move synchronously. When the cutting structure 205 cuts the anti-pressure plates due to offset, the anti-pressure plates The pressure plate 520 will start to squeeze the sliding rod 518 due to the pressure it senses. The sliding rod 518 will start to squeeze the third compression spring 517 in the sleeve 516 during the buffering process. When the third compression spring 517 senses the pressure, it will exert a rebound force on the pressure sensor 519, collect the values ​​for warning, and the pressure plate 520 will cause the two sets of sensors to be unable to be located at the same height distance during the squeezing process, thereby improving the multi-layer warning function of the structure, avoiding secondary damage to the door and window cutting, improving the precision of the door and window cutting, and improving the working effect of the device.

[0052] When the cutting structure 205 is cut by the offset anti-pressure plate, the anti-pressure plate 520 will start to extrude the sliding rod 518 due to the pressure, and the sliding rod 518 will start to extrude the third compression spring 517 in the sleeve pipe 516 during the buffering process, and the third compression spring 517 will rebound and apply a force on the pressure sensor 519 when it senses the pressure, and the collected value will alarm, and the anti-pressure plate 520 will cause the two groups of sensors to be unable to be located at the same height distance during the extrusion process, thereby improving the multi-layer alarm function of the structure, avoiding the secondary damage of the door and window cutting, improving the door and window cutting precision effect, and improving the working effect of the device.

[0053] The sliding pipe 503 is driven to slide in the sleeve 502, and the abutting plate 504 starts to extrude the second compression spring 505, then the door and window to be cut are placed on the two groups of abutting plates 504, then the magnetic connection between the first electromagnetic block 507 and the second electromagnetic block 508 is disconnected, the second compression spring 505 starts to rebound when it senses the disappearance of the pressure, drives the abutting plate 504 to extrude the door and window, then the pushing of the clamping plate 405 is disconnected, and the first compression spring 404 drives the clamping plate 405 to elastically limit the door and window when it senses the disappearance of the pressure, so that the clamping has a buffering effect, and the wrapping and limiting effect is improved, and the disassembly and assembly are convenient.

[0054] When the third motor 306 is started for an irregular door and window, the threaded rod 302 is driven to rotate, and the two groups of sliding blocks 304 are driven to slide in the sliding cavity 303 while the threaded rod 302 rotates, and the two groups of fourth fixed plates 401 are adjusted in position while the sliding blocks 304 slide, then the fourth motor 307 is started according to the shape of the door and window, the fourth motor 307 drives the fourth fixed plate 401 to rotate, and the fourth fixed plate 401 is limited after rotating to a specified angle, thereby improving the limiting compatibility effect and the auxiliary limiting working effect.

[0055] The second electric push rod 203 is started to push the cutting structure 205 to cut the door and window, and in order to improve the cutting range, the electric sliding table 202 is started to drive the cutting structure 205 to translate and cut, the first motor 201 is started to drive the cutting structure 205 to rotate, thereby improving the cutting range of the device; before cutting, the fourth electric push rod 514 is started to push the two groups of anti-pressure plates 520 to move below the cutting structure 205 and avoid the output end range of the cutting structure, thereby improving the passive support stability effect of the structure.
