Description

Technical Field

[0001] This utility model relates to the field of electric scissors technology, and more specifically to a highly protective electric scissors. Background Technology

[0002] Electric scissors are double-insulated handheld electric tools that use a single-phase series motor as power and drive the working head through a transmission mechanism to perform cutting operations. They are characterized by their ability to easily cut steel plates of various shapes, light weight, and safety and reliability. They are widely used in sheet metal applications in the automotive, shipbuilding, aircraft and repair industries for cutting thin plates, metal plates and other sheet metal.

[0003] Electric scissors consist of a motor, gearbox, eccentric shaft-linkage mechanism, switch, non-reconnectable plug, and blades. Electric scissors are quite sharp, so their use is somewhat dangerous. When using them, one must concentrate on cutting the work, and other personnel are prohibited from chatting with the operator or distracting the operator in any other way.

[0004] While electric scissors are generally considered safe, and the blades close electronically, placing fingers or other body parts near the blades during use can pose a risk as the electronic device automatically closes the blades. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a highly protective electric scissors to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a highly protective electric scissors, including a scissor handle, an electronic control center fixedly connected to the side of the scissor handle, a cutting blade movably connected to the side of the electronic control center away from the scissor handle, a scissor switch fixedly connected to the top of the electronic control center, limit mechanisms fixedly connected to both sides of the electronic control center, and detection mechanisms movably connected to the sides of the two limit mechanisms away from the electronic control center; the detection mechanism includes a mounting plate for fixing, a rotating shaft movably connected to the top of the mounting plate, an adjusting handwheel fixedly connected to the top of the rotating shaft, a connecting plate fixedly connected to the side of the rotating shaft, and an infrared thermometer fixedly connected to the side of the connecting plate.

[0007] Furthermore, an auxiliary switch is fixedly connected to the side of the scissor switch. When the scissor switch is pressed but the auxiliary switch is not pressed, the control center will issue an alarm.

[0008] Furthermore, a microcurrent is provided at the closing point of the cutting blade, and when the microcurrent of the cutting blade comes into contact with the same resistance as the human body, the cutting blade cannot close.

[0009] Furthermore, the connecting plate is semi-arc-shaped, and the rotating shaft is located on the side of the connecting plate away from the infrared thermometer, while the infrared thermometer points to the center of the cutting blade.

[0010] Furthermore, the limiting mechanism includes a support spring adapted to the side of the connecting plate, a limiting rod fixedly connected to the side of the support spring away from the connecting plate, and a limiting sleeve movably connected to the side of the limiting rod.

[0011] Furthermore, a limiting sleeve is movably connected to the side of the limiting rod away from the limiting block, and the side of the limiting sleeve away from the limiting rod is fixedly connected to the side of the electrical control center. The supporting spring is located on the outside of the limiting sleeve.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model is equipped with an adjusting handwheel, a rotating shaft, a connecting plate, and an infrared thermometer. When performing shearing work, rotating the adjusting handwheel drives the rotating shaft to rotate, which in turn drives the connecting plate to detect the cutting edge. The connecting plate then drives the infrared thermometer to detect the cutting edge. The infrared thermometers on both sides simultaneously detect the cutting edge. When the temperature of a human body is detected at the location of the cutting edge, the cutting edge is prevented from closing, thus achieving a protective effect.

[0014] 2. This utility model, by providing a limiting block and a supporting spring, ensures that when the connecting plate rotates, the side of the connecting plate contacts the limiting block, while the side of the limiting block away from the connecting plate contacts the supporting spring. The compressed supporting spring applies elastic force to the limiting block, thereby fixing the position of the connecting plate and ensuring that the position of the connecting plate does not move. This ensures that the connecting plate is aligned with the cutting blade for detection, thus guaranteeing the detection effect. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 This utility model provides a highly protective electric scissors, including a scissor handle 1, an electric control center 2 fixedly connected to the side of the scissor handle 1, a cutting blade 4 movably connected to the side of the electric control center 2 away from the scissor handle 1, a scissor switch 3 fixedly connected to the top of the electric control center 2, limit mechanisms 6 fixedly connected to both sides of the electric control center 2, and detection mechanisms 7 movably connected to the sides of the two limit mechanisms 6 away from the electric control center 2. A secondary switch 5 is fixedly connected to the side of the scissor switch 3. When the scissor switch 3 is pressed and the secondary switch 5 is not pressed, the electric control center 2 will issue an alarm. A microcurrent is provided at the closing point of the cutting blade 4, and when the microcurrent of the cutting blade 4 comes into contact with the same resistance as the human body, the cutting blade 4 cannot close.

[0023] In this embodiment, when the scissor switch 3 is pressed while the auxiliary switch 5 is not pressed, the user's other hand is not on the location of the auxiliary switch 5. Therefore, an audible sound is emitted to remind the user to pay attention to safety. The closing point of the cutting blade 4 is provided with a micro-current. When the micro-current of the cutting blade 4 comes into contact with the same resistance as the human body, there is a possibility that the cutting blade 4 will come into contact with the human body. Therefore, the cutting blade 4 cannot close, ensuring the safety of use.

[0024] Reference Figure 3 and Figure 4 The detection mechanism 7 includes a mounting plate 701 for fixing. A rotating shaft 703 is movably connected to the top of the mounting plate 701. An adjusting handwheel 702 is fixedly connected to the top of the rotating shaft 703. A connecting plate 704 is fixedly connected to the side of the rotating shaft 703. An infrared thermometer 705 is fixedly connected to the side of the connecting plate 704. The connecting plate 704 is semi-arc-shaped, and the rotating shaft 703 is located on the side of the connecting plate 704 away from the center of the infrared thermometer 705. The infrared thermometer 705 points to the center of the cutting blade 4.

[0025] In this embodiment, when the adjustment handwheel 702 rotates, it drives the rotating shaft 703 to rotate. When the rotating shaft 703 rotates, it drives the connecting plate 704 to rotate, which in turn causes the infrared thermometer 705 to rotate. This ensures that the infrared thermometer 705 is facing the center of the cutting blade 4, and infrared thermometers 705 are provided on both sides of the cutting blade 4 to ensure detection accuracy and overall protection. Furthermore, the rotating shaft 703 is located on the side of the connecting plate 704 away from the center of the infrared thermometer 705, allowing the connecting plate 704 to rotate at a larger angle.

[0026] Reference Figure 4 and Figure 5 The limiting mechanism 6 includes a support spring 604 adapted to the side of the connecting plate 704. A limiting rod 602 is fixedly connected to the side of the support spring 604 away from the connecting plate 704. A limiting sleeve 603 is movably connected to the side of the limiting rod 602. The limiting sleeve 603 is movably connected to the side of the limiting rod 602 away from the limiting block 601. The side of the limiting sleeve 603 away from the limiting rod 602 is fixedly connected to the side of the electric control center 2. The support spring 604 is located outside the limiting sleeve 603.

[0027] In this embodiment, the side of the limiting block 601 away from the connecting plate 704 contacts the support spring 604, and the support spring 604 is in a compressed state, so it will apply a spring force to the limiting block 601. After the limiting block 601 is subjected to the spring force, it will apply a force to the connecting plate 704, which will restrict the position of the connecting plate 704 and prevent the connecting plate 704 from automatically shifting during the shearing operation, thus ensuring the accuracy of the detection in this application.

[0028] The working principle of this utility model is as follows: When performing cutting work, one hand holds the scissor handle 1. After the thumb of the hand holding the scissor handle 1 presses the scissor switch 3, the electronic control center 2 will control the cutting blade 4 to close, and the cutting work can be carried out at this time. The other hand needs to press the auxiliary switch 5. Otherwise, the electronic control center 2 will issue an alarm to remind the user to avoid putting the other hand inside the cutting blade 4.

[0029] Before cutting, rotate the adjusting handwheel 702. When the adjusting handwheel 702 rotates, it drives the rotating shaft 703 to rotate. When the rotating shaft 703 rotates, it drives the connecting plate 704 to rotate, which in turn causes the infrared thermometer 705 to rotate. The infrared thermometer 705 is positioned so that it faces the center of the cutting blade 4. Infrared thermometers 705 are installed on both sides of the cutting blade 4 to ensure detection accuracy. When the scissor switch 3 is pressed and the electronic control center 2 controls the cutting blade 4 to close, if the infrared thermometer 705 detects a human body at the location of the cutting blade 4, it will prevent the cutting blade 4 from closing to avoid injury.

[0030] Furthermore, when the connecting plate 704 rotates, the side of the connecting plate 704 contacts the limiting block 601, and the side of the limiting block 601 away from the connecting plate 704 contacts the support spring 604. Since the support spring 604 is in a compressed state, it will apply a spring force to the limiting block 601. After the limiting block 601 is subjected to the spring force, it will apply a force to the connecting plate 704. At this time, the position of the connecting plate 704 will be restricted, preventing the connecting plate 704 from automatically shifting during the shearing operation, thus ensuring the accuracy of the detection in this application.

[0031] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
