[0062] As a further explanation of the present invention, the output shaft 202 of the motor 201 is drivingly connected to the first slider 301 through a driving mechanism 400, and the driving mechanism 400 includes a first through hole 401, a third gear 402, a first C-shaped block 403, a second slider 404, a second guide rail 405, a first magnet 406, a first electromagnet 407, a second electromagnet 408, a first spring 409, a second spring 410, a fourth gear 411, a third rotating shaft 412, a first disc 413, an arc-shaped rack 414, a fifth gear 415, a fourth rotating shaft 416, a sixth gear 417, a first cylinder 418, a first guide groove 419, and a first pin 420;

[0063] The output shaft 202 of the motor 201 is arranged in the first through hole 401 and moves along it. The first through hole 401 is coaxially opened on the third gear 402. The third gear 402 is arranged in the first C-shaped block 403 and rotates along it. The middle part of the first C-shaped block 403 is fixedly connected to one end of the second slider 404. The second slider 404 is arranged in the second guide rail 405 and moves along it. The second guide rail 405 is fixedly connected to the bracket 102.

[0064] The third gear 402 can mesh with the fourth gear 411, the fourth gear 411 is coaxially fixed with one end of the third rotating shaft 412, the third rotating shaft 412 is installed on the bracket 102 through a bearing, the other end of the third rotating shaft 412 is coaxially fixed with the first disc 413, the arc-shaped rack 414 is coaxially fixed to one side of the surface of the first disc 413, the arc-shaped rack 414 can mesh with the fifth gear 415, the fifth gear 415 is coaxially fixed with one end of the fourth rotating shaft 416, the fourth rotating shaft 416 is installed on the bracket 102 through a bearing, the other end of the fourth rotating shaft 416 is coaxially fixed with the sixth gear 417, and the sixth gear 417 can mesh with the arc-shaped rack 414;

[0065] The fifth gear 415 is coaxially fixed to one end of the first cylinder 418, and the other end of the first cylinder 418 is mounted on the bracket 102 through a bearing. The side of the first cylinder 418 is provided with a threaded first guide groove 419, and one end of the first pin shaft 420 moving along the first guide groove 419 is arranged in the first guide groove 419, and the other end of the first pin shaft 420 is fixedly connected to the first slider 301.

[0066] The motor 201 of the present invention drives the third gear 402 to rotate through the output shaft 202, and intermittently realizes the meshing of the third gear 402 with the fourth gear 411, so that the reciprocating motion of the first slider 301 along the length direction of the first guide rail 302 is realized through the rotation of the first cylinder 418 and the configuration relationship between the first guide groove 419 and the first pin shaft 420, thereby realizing the driving of the first slider 301 by the motor 201, and finally realizing the hole opening of the side wall of the pipe 103 by the hole opening knife 305.

[0067] The motor 201 of the present invention drives the third gear 402 to rotate synchronously through the output shaft 202, and when the first magnet 406 and the first electromagnet 407 attract and overlap each other, the second slider 404 drives the third gear 402 to engage with the fourth gear 411 through the first C-shaped block 403. At this time, the rotation of the third gear 402 synchronously drives the rotation of the fourth gear 411, the third rotating shaft 412 and the first disc 413, and the rotation of the first disc 413 further drives the arc rack 414 to rotate synchronously. The fourth rotating shaft 416 rotates, and the arc-shaped rack 414 intermittently meshes with the fifth gear 415 or the sixth gear 417, thereby realizing the forward and reverse rotation of the fourth rotating shaft 416. The forward and reverse rotation of the fourth rotating shaft 416 synchronously drives the forward and reverse rotation of the first cylinder 418, and through the first guide groove 419 opened on the first cylinder 418 and the configuration relationship between the first guide groove 419 and the first pin shaft 420, the first slider 301 is smoothly driven to reciprocate along the length direction of the first guide rail 302.

[0068] The second slider 404 is a dovetail slider, and the second guide rail 405 is a dovetail guide rail, thereby ensuring that the second slider 404 can only be arranged in the second guide rail 405 and reciprocate along the length direction thereof.

[0069] The motor 201 is a rotary motor, thereby ensuring that the motor 201 can smoothly drive the third gear 402 to rotate through the output shaft 202 .

[0070] The second guide rail 405 is a guide rail with a hollow bottom, so as to ensure that the second slider 404 can pass through the second guide rail 405 and can be arranged inside the second slider 404 and move along it.

[0071] The power modules of the first electromagnet 407 and the second electromagnet 408 include a battery, an electric control module, and a wireless communication module.

[0074] The cross-sectional shape of the output shaft 202 of the motor 201 is a square, and the cross-sectional shape of the first through hole 401 is a square matching the cross-sectional shape of the output shaft 202 .

[0075] The present invention ensures synchronous rotation of the output shaft 202 and the third gear 402 , and the third gear 402 can reciprocate along the length direction of the output shaft 202 .

[0076] The first spring 409 and the second spring 410 are completely equal springs.

[0077] The present invention ensures that when the first magnet 406 is in a balanced position, the second slider 404 is located in the middle of the second guide rail 405. At this time, the third gear 402 will not mesh with the fourth gear 411. When the first magnet 406 and the first electromagnet 407 attract each other, the first magnet 406 approaches the first electromagnet 407 and compresses the first spring 409, thereby achieving the meshing of the third gear 402 and the fourth gear 411.

[0078] The arc angle of the arc-shaped rack 414 is less than 180 degrees.

[0079] The present invention ensures that the arc-shaped rack 414 will not mesh with the fifth gear 415 and the sixth gear 417 at the same time, and the arc-shaped rack 414 is just disengaged from the sixth gear 417 when meshing with the fifth gear 415, thereby smoothly driving the fourth rotating shaft 416 to rotate forward and reverse.

[0080] The thread angle range of the first guide groove 419 track is 55 degrees.

[0081] The present invention further ensures that the first cylinder 418 can smoothly rotate in the forward and reverse directions through the configuration relationship of the first guide grooves 419 and 320 to drive the reciprocating motion of the first slider 301 .

[0082] As a further explanation of the present invention, the motor 201 also drives a clamping mechanism 500, which includes a first guide rod 501, a third guide rail 502, a first fixing plate 503, a first clamping block 504, a first rack 505, a seventh gear 506, a second rack 507, a second guide rod 508, a fourth guide rail 509, a first connecting rod 510, and a second clamping block 511;

[0084] The motor 201 of the present invention drives the first clamping block 504 and the second clamping block 511 through the output shaft 202 to overlap with the outer surface of the pipe 103 at the same time, ensuring that the pipe 103 can remain stable during the hole opening and cutting process, thereby improving the hole opening accuracy.

[0085] Among them, the motor 201 drives the first guide rod 501 through the output shaft 202 to move along the length direction of the third guide rail 502 toward the side close to the pipe 103, so that the first clamping block 504 overlaps the outer surface of the pipe 103. During the movement of the first guide rod 501, the engagement of the first rack 505 with the seventh gear 506 drives the synchronous rotation of the seventh gear 506. The rotation of the seventh gear 506 further drives the second guide rod 508 to move along the length direction of the fourth guide rail 509. At this time, the fourth guide rail 509 drives the second clamping block 511 to overlap the outer surface of the pipe 103 through the first connecting rod 510, thereby realizing the simultaneous clamping of the pipe 103 by the first clamping block 504 and the second clamping block 511.

The left and right motion of the first fixed plate 503 drives the synchronous left and right motion of the third pin shaft 614, so that the third pin shaft 614 drives the first guide rod 501 to reciprocate along its length direction during the movement in the third guide groove 615, finally realizing the driving of the reciprocating motion of the first guide rod 501.

[0101] Among them, the structure composed of the first lever 617, the first limit block 618, and the fourth spring 619 has two groups of centrally symmetrical distribution about the center of the trajectory shape of the third guide groove 615, ensuring that the third pin shaft 614 can only move in one direction along the third guide groove 615 and will not move in the opposite direction.

When the first fixed plate 503 moves to the leftmost side and overlaps the first push switch 711, the first push switch 711 drives the first magnet 406 and the second electromagnet 40 8 attract and overlap each other, so that the third gear 402 is meshed with the eighth gear 601, and then the second cylinder 607 is driven to rotate, and the first fixing plate 503 is further driven to move from left to right to the rightmost side through the configuration relationship between the second guide groove 608 and the second pin shaft 609. In the process of the first fixing plate 503 moving from left to right, the third pin shaft 614 is synchronously driven to start the second sensor 712.

The battery is fixed on the upper surface of the base plate 101, and the wireless communication module is wirelessly connected to the second sensor 712.
