DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings: like Figures 1-8As shown, this embodiment provides a handheld wire cutting device for wiring an electrical cabinet, comprising a handheld portion 1, a storage battery 2 is fixedly mounted on the bottom of the handheld portion 1, and a U-shaped wire cutting seat 3 is fixedly mounted on the top of the handheld portion 1. The U-shaped wire cutting seat 3 is provided with a limited installation groove, a synchronous drive component 4 is installed in the limited installation groove, a push-type limited toggle component 5 is installed on the synchronous drive component 4, and the push-type limited toggle component 5 is divided into two groups, and the two groups of push-type limited toggle components 5 are symmetrically distributed, which are used to toggle and limit the connecting wire. A clearance through-hole groove is provided on the side wall of the U-shaped wire cutting seat 3, and the clearance through-hole groove corresponds horizontally to the push-type limited toggle component 5. An extension installation bar 6 is fixedly installed at one end of the bottom of the U-shaped wire cutting seat 3, and a limited sliding groove is provided on the extension installation bar 6. A clamping type pulling wire cutting component 7 is installed in the limited sliding groove. The clamping type pulling wire cutting component 7 is used to clamp and pull one end of the connecting wire. When in use, hold the handheld part 1, and the handheld part 1 has a built-in energy storage battery 2 to provide the necessary power support for the device. At the top of the handheld part 1, the U-shaped wire cutting seat 3 is firmly installed to become a cutting platform for the electrical connecting wire, and the connecting wire is placed on the U-shaped wire cutting seat 3. At this time, the synchronous drive assembly 4 in the limit installation groove on the U-shaped wire cutting seat 3 is started, and drives the two sets of symmetrically distributed push-type limit toggle assemblies 5 to work. The push-type limit toggle assembly 5 toggles the electrical connection wire to facilitate driving the electrical connection wire forward, facilitate automatic wire cutting, and ensure the stability of the position of electrical connection wires of different thicknesses, effectively avoiding the loosening or offset of the connection wire, and avoiding affecting the accuracy of wire cutting of the electrical connection wire. While limiting the electrical connection wire, the side wall of the U-shaped wire cutting seat 3 is designed with a clearance through-hole groove corresponding to the horizontal level of the push-type limit toggle assembly 5, which provides the necessary space for the movement of the push-type limit toggle assembly 5. At the same time, the clamping pull wire cutting assembly 7 installed on the extended installation bar 6 is stably installed through the limit slide groove, and has the function of clamping and pulling one end of the connection wire. With simple operation, the clamping pull wire cutting assembly 7 can clamp the electrical connection wire and pull it as needed to achieve orderly management and rapid wire cutting of the electrical connection wire, which is more convenient to use, has a higher degree of automation, and improves the efficiency of wire cutting.

[0025] The synchronous drive assembly 4 includes a drive motor 401 and a bidirectional threaded rod 402. The drive motor 401 is fixed on the inner wall of one end of the limit installation groove. The bidirectional threaded rod 402 is rotatably installed on the inner wall of the other end of the limit installation groove through a first rotating joint 403. One end of the bidirectional threaded rod 402 is fixedly connected to the output shaft of the drive motor 401. A threaded slider 404 is installed on the bidirectional threaded rod 402. The threaded slider 404 is slidably engaged in the limit installation groove. There are two threaded sliders 404. The two threaded sliders 404 are respectively located at the reverse thread ends of the bidirectional threaded rod 402. The first L-shaped connecting frame 405 and the second L-shaped connecting frame 406 are respectively fixedly installed on the two threaded sliders 404. Two sets of push-type limit toggle assemblies 5 are respectively located at one end of the first L-shaped connecting frame 405 and the second L-shaped connecting frame 406. When in use, the drive motor 401 fixed on the inner wall of one end of the limit installation groove is started. The drive motor 401 then drives the bidirectional threaded rod 402 fixedly connected to its output shaft to rotate. The bidirectional threaded rod 402 stably rotates on the inner wall of the other end of the position limiting installation groove through the first rotating joint 403. As the bidirectional threaded rod 402 rotates, the two threaded sliders 404 installed thereon begin to move along different screw thread directions. The two threaded sliders 404 are respectively slidably engaged in the position limiting installation groove, ensuring the stability and accuracy of their movement. The movement of the threaded sliders 404 drives the first L-shaped connecting frame 405 and the second L-shaped connecting frame 406 respectively fixed thereon to move synchronously. One end of the two L-shaped connecting frames is respectively connected to two sets of push-type position limiting toggle assemblies 5. Therefore, as the L-shaped connecting frames move, the two sets of push-type position limiting toggle assemblies 5 also start to work, and they symmetrically toggle and limit the connecting wires, ensuring the stable position of the electrical connecting wires, and can simultaneously limit and toggle the two electrical connecting wires, realizing the precise management and positioning of the connecting wires, and improving the efficiency of wire cutting.

[0026] The push-type limit-shifting assembly 5 includes a vertical limit seat 501 and a vertically extending bar 502. The vertical limit seat 501 is fixed to one end of the first L-shaped connecting frame 405 and the second L-shaped connecting frame 406. The vertically extending bar 502 is fixedly installed on the top of the vertical limit seat 501 through a connecting column head 503. A vertical shifting roller 504 is rotatably installed on the inner wall of the vertical limit seat 501. One end of the vertical shifting roller 504 is fixedly connected to the output shaft of the first built-in motor 505 installed on the vertical limit seat 501. A square connecting column 506 is fixedly installed at the bottom of the vertically extending bar 502. A suspended plate 507 is fixedly installed at one end of the square connecting column 506. A vertical pressing slide rod 508 is slidably installed on the suspended plate 507. A lifting head 509 is fixedly installed at one end of the vertical pressing slide bar 508, and the lifting head 509 is slidably inserted on the vertically extended bar 502, and a horizontal limit seat 510 is fixedly installed at the other end of the vertical pressing slide bar 508. A horizontal toggle roller 511 is rotatably installed on the inner wall of the horizontal limit seat 510, and one end of the horizontal toggle roller 511 is fixedly connected to the output shaft of the second built-in motor 512 installed on the horizontal limit seat 510, and an annular pressing block 513 is fixedly sleeved on the vertical pressing slide bar 508, and the annular pressing block 513 is elastically connected to the suspended plate 507 through a pressing spring 514. When in use, the first built-in motor 505 fixed on the vertical limit seat 501 is started to drive the vertical toggle roller 504 to start rotating. The rotation of the vertical toggle roller 504 will drive the connecting wire it contacts to be toggled sideways, ensuring that the connecting wire is limited and preliminarily arranged in the vertical direction, and the operating lifting head 509 slides on the vertically extending bar 502, thereby driving the vertical pressing slide bar 508 and the horizontal limiting seat 510 connected thereto to slide along the suspended plate 507. In this process, the annular pressing block 513 maintains an elastic connection with the suspended plate 507 through the pressing spring 514, which not only ensures the stability of the movement of the vertical pressing slide bar 508, but also provides a certain buffering effect when necessary. Subsequently, the second built-in motor 512 installed on the horizontal limiting seat 510 is started to drive the horizontal toggle roller 511 to rotate. The rotation of the horizontal toggle roller 511 will further toggle the connecting wire horizontally, ensuring that the connecting wire is also limited and arranged in the horizontal direction. Through the coordinated work of the vertical toggle roller 504 and the horizontal toggle roller 511, the push-type limit toggle assembly 5 can toggle and limit the connecting wire in all directions, so that it can be neatly arranged on the U-shaped wire cutting seat 3, greatly improving the management efficiency and neatness of the connecting wire, and can realize the automatic advancement of the connecting wire, providing strong support for wire cutting and improving wire cutting efficiency.

[0027] The clamping type wire pulling and cutting assembly 7 includes a servo motor 701 and a propulsion lead screw 702. The servo motor 701 is fixed on the inner wall at one end of the limit chute. The propulsion lead screw 702 is rotatably installed on the inner wall at the other end of the limit chute through a second rotating joint 703, and one end of the propulsion lead screw 702 is fixedly connected to the output shaft of the servo motor 701. A propulsion slider 704 is threadedly installed on the propulsion lead screw 702. The propulsion slider 704 is slidably clamped in the limit chute. A first L-shaped propulsion block 705 is fixedly installed on the propulsion slider 704. One end of the first L-shaped propulsion block 705 is fixedly installed with a second L-shaped propulsion block 706. One end of the second L-shaped propulsion block 706 is fixedly installed with a supporting top plate 707. One end of the top of the supporting top plate 707 is fixedly installed with a fixed clamping plate 708. The other end of the supporting top plate 707 is fixedly installed with a vertical fixed side plate 709. A horizontal telescopic push rod 710 is fixedly installed on the vertical fixed side plate 709. The telescopic end of the horizontal telescopic push rod 710 is fixedly installed with a movable clamping plate 711. The movable clamping plate 711 corresponds to the fixed clamping plate 708. When in use, the servo motor 701 fixed on the inner wall at one end of the limit chute is started. The rotation of the servo motor 701 drives the propulsion lead screw 702 fixedly connected to its output shaft to start rotating. The rotation of the propulsion lead screw 702 causes the threadedly installed propulsion slider 704 to slide smoothly in the limit chute. The movement of the propulsion slider 704 drives the first L-shaped propulsion block 705 and the second L-shaped propulsion block 706 fixedly installed thereon to move synchronously. With the movement of these two L-shaped propulsion blocks, the supporting top plate 707 at their ends gradually approaches one end of the connecting wire. When the supporting top plate 707 reaches the specified position, the fixed clamping plate 708 fixed on it is already on one side of the connecting wire. At this time, the horizontal telescopic push rod 710 is started, and its telescopic end pushes the movable clamping plate 711 towards the fixed clamping plate 708 until the two tightly clamp one end of the connecting wire. After the clamping is completed, the servo motor 701 continues to drive the propulsion lead screw 702 to rotate. Through the transmission of the propulsion slider 704, the first L-shaped propulsion block 705 and the second L-shaped propulsion block 706, it drives the supporting top plate 707 and the clamped end of the connecting wire to perform a pushing operation. The clamping type wire pulling and cutting assembly 7 realizes the precise clamping and pulling of the connecting wire through the coordinated work of the servo motor 701, the propulsion lead screw 702 and the horizontal telescopic push rod 710, greatly improving the automation degree and operation efficiency of the connecting wire management.
