DETAILED DESCRIPTION

[0026] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figure 1-Figure 5 As shown, the manual metal sheet cutting tool provided in this embodiment includes a tool body 1, the tool body 1 includes a tool cutting end 101 and a tool braking end 102, the tool cutting end 101 and the tool braking end 102 form a C-shaped structure, a sliding cutting tool 2 is fixedly arranged at the bottom of the tool cutting end 101, a cutting handle 4 is fixedly arranged at one end of the tool braking end 102 away from the tool cutting end 101, a cutting brake handle 3 is rotatably arranged above the cutting handle 4 at the tool braking end 102, and the cutting brake handle 3 includes a wire rope brake wheel 301, and the wire rope brake wheel 301 is rotatably arranged on the tool braking end 102 through rivets;

[0028] A sliding cutting tool 2 is fixedly arranged on the tool cutting end 101, and the sliding cutting tool 2 includes an upper sliding cutting blade 201 and a lower sliding cutting blade 202. The upper sliding cutting blade 201 is above the lower sliding cutting blade 202, and the angle between the upper sliding cutting blade 201 and the lower sliding cutting blade 202 is in the range of 30-45 degrees. Therefore, when it is necessary to slide cut a metal sheet, the metal sheet can be directly placed inside the sliding cutting tool 2, and the metal sheet can be directly slide cut by dragging the tool body 1, and the structure is simple;

[0029] The traditional method is to use scissors to cut open. Due to the uneven force, the metal sheet will be seriously damaged. When others are needed to assist, other staff members may be injured by excessive force. The blade of the device is placed inside the device, so it will not cause harm to the staff, improving the safety of use. At the same time, the metal sheet can be directly cut by pulling the tool body 1, which greatly improves the work efficiency.

[0030] A cutting brake chamber 105 and a wire rope brake chamber 106 are provided inside the tool body 1, and the cutting brake chamber 105 and the wire rope brake chamber 106 are connected. A cutting brake member 6 is provided inside the cutting brake chamber 105 by rivet rotation. The cutting brake member 6 includes a wire rope brake rod 601, and the wire rope brake rod 601 is fixedly connected to the wire rope brake wheel 301 through a wire rope 10. The wire rope brake rod 601 is fixedly connected to the cutting brake chamber 105 through a return spring 7. A cutting blade 8 is connected to the cutting brake member 6, and the angle between the cutting blade 8 and the wire rope brake rod 601 is in the range of 100-120 degrees, and the cutting blade 8 is close to the sliding cutting tool 2;

[0031] The steel wire rope 10 passes through the steel wire rope brake chamber 106 and extends to the interior of the cutting brake chamber 105, and one end of the steel wire rope 10 is fixedly connected to the steel wire rope brake wheel 301, and the other end of the steel wire rope 10 is fixedly connected to the steel wire rope brake rod 601, and the steel wire rope brake rod 601 is provided with a steel wire rope fixing hole 602, and the steel wire rope 10 is fixedly arranged on the steel wire rope fixing hole 602;

[0032] Furthermore, since it is often necessary to first cut a notch in the metal sheet before sliding cutting, and then slide cutting is performed through the notch, the device has a certain cutting function. During use, a handle rotation groove 107 is provided on the tool braking end 102, and the wire rope brake wheel 301 is rotatably arranged inside the handle rotation groove 107 by rivets. By holding the cutting handle 4 on the tool body 1 by hand, and then pressing the cutting brake handle 3 with the thumb, the cutting brake handle 3 is rotated downward, and the cutting blade 8 and the wire rope brake rod 601 form a V-shaped structure, and the wire rope brake rod 601 is used to rotate the cutting blade 8 to pull the wire rope. The rope 10 and the steel wire rope 10 cause the cutting brake 6 to rotate during the process of pulling the steel wire rope brake rod 601. The cutting blade 8 rotates downward under the action of the cutting brake 6 and cuts the metal sheet under the interaction with the sliding cutting blade 202. The upper end of the reset spring 7 is fixedly connected to the steel wire rope brake rod 601, and the lower end of the reset spring 7 is fixedly connected to the inside of the cutting brake chamber 105. After the cutting is completed, the steel wire rope brake rod 601 will return to its original state under the action of the reset spring 7, so the cutting blade 8 will return to its initial position and proceed to the next cutting process. The structure is simple, which improves the convenience and practicality of use.

[0033] In this embodiment, if Figure 1 As shown, an infrared fixing block 104 is fixedly disposed at the bottom of the tool braking end 102, and an infrared generator 5 is rotatably disposed inside the infrared fixing block 104;

[0034] During the process of cutting or sliding the metal sheet, the sliding cutter 2 can be corrected by adjusting the infrared generator 5 on the infrared fixing block 104 to prevent the sliding cutter 2 from slipping, which is beneficial to saving the metal sheet and improving the practicality of the device.

[0035] A sliding cut handle groove 103 is provided between the tool cutting end 101 and the tool braking end 102, and an anti-slip sleeve 9 is provided on the sliding cut handle groove 103;

[0036] The cutting handle 4 and the infrared generator 5 are both fixedly provided with anti-slip patterns 11;

[0037] The sliding cutting handle groove 103 can be used to hold the tool body 1, which is beneficial to improve the overall stability of the tool body 1 during the sliding cutting process. At the same time, the anti-slip sleeve 9 and anti-slip pattern 11 can increase the friction between the hand and prevent the hand from slipping during use, thereby improving the convenience of use.

[0038] like Figure 1-Figure 5 As shown, the principle of the manual metal sheet cutting tool provided in this embodiment is as follows:

[0039] A sliding cutting tool 2 is fixedly arranged on the tool cutting end 101, and the sliding cutting tool 2 includes an upper sliding cutting blade 201 and a lower sliding cutting blade 202. The upper sliding cutting blade 201 is above the sliding cutting blade 202, and the angle between the upper sliding cutting blade 201 and the lower sliding cutting blade 202 is in the range of 30~45°. Therefore, when it is necessary to slide cut the metal sheet, the metal sheet can be directly placed inside the sliding cutting tool 2, and the metal sheet can be directly slide cut by dragging the tool body 1.

[0040] By holding the cutting handle 4 on the tool body 1 with the hand, and then pressing the cutting brake handle 3 with the thumb, the cutting brake handle 3 will form a V-shaped structure with the wire rope brake rod 601 during the downward rotation of the cutting brake handle 3, and the wire rope brake rod 601 is used to rotate the cutting blade 8 and pull the wire rope 10. The wire rope 10 causes the cutting brake member 6 to rotate during the pulling of the wire rope brake rod 601. The cutting blade 8 rotates downward under the action of the cutting brake member 6, and cuts the metal sheet under the interaction with the lower cutting blade 202. The upper end of the reset spring 7 is fixedly connected to the wire rope brake rod 601, and the lower end of the reset spring 7 is fixedly connected to the inside of the cutting brake chamber 105. After the cutting is completed, the wire rope brake rod 601 will return to its original state under the action of the reset spring 7, so the cutting blade 8 will return to its initial position and proceed to the next cutting process.
