Description
Technical Field
[0001] This application relates to the field of jigsaw technology, specifically to an intelligent protective jigsaw device. Background Technology
[0002] A jigsaw is a tool primarily used for cutting metals and non-ferrous metals. It has a stronger chip-handling capacity when cutting metals, and larger saw teeth. It is also more efficient when cutting wood and other wood products. Carbon steel jigsaws are used for cutting various types of wood and non-metals; the saw teeth are sharpened into a conical shape, resulting in fast cutting and a stronger chip-handling capacity.
[0003] Traditional jigsaws are typically started directly and placed on the surface of the object to be cut before cutting. However, the jigsaw blade lacks protective devices, which can lead to blade damage or injury to the user. Therefore, an intelligent protective jigsaw device is proposed to address these issues. Summary of the Invention
[0004] The purpose of this application is to provide an intelligent protective jigsaw device to solve the problem that the lack of protective equipment on the surface of the jigsaw blade can lead to injury to the saw blade or the user.
[0005] To achieve the above objectives, this application provides the following technical solution:

The plug is placed in the slots of the base. A bolt penetrating the fixed plate and the side wall of the base is rotatably connected at the center of the connecting plate. A nut is threadedly connected to the outer side of the bolt away from the connecting plate. The nut is fixedly connected to the base.
[0008] Preferably, the guide body includes a top plate, a connecting block, a rotating wheel, a rubber block, an insert, and a fixing block. The top plate is disposed inside a fixed shell, and vertical rods are evenly distributed throughout the top plate. Connecting blocks are fixedly connected to the left and right sides of the bottom of the top plate. Two horizontally arranged rotating wheels distributed front and back are rotatably connected to the bottom of the connecting blocks. A rubber block is installed in the top of the connecting blocks, and an insert is disposed inside the rubber block. A fixing block is evenly distributed and fixedly connected to the top of the insert. The top of the fixing block is fixedly connected to the top plate.
[0009] Preferably, the connecting block is disposed in the slot of the base, the two fixing plates are respectively disposed on the left and right sides of the connecting block, and pressure sensors are fixedly connected to the left and right sides of the top center of the connecting block, with the top of the pressure sensors in contact with the top plate.
[0010] Preferably, the protective body includes a protective shell, a limiting body, a rotating plate, a fixing frame, a slider, a limiting rod, a connecting column, and a rubber ring. A connecting column is fixedly connected to the top of the protective shell on the side closest to the jigsaw body. A rubber ring is installed on the outside of the connecting column. Both the connecting column and the rubber ring are located in a fixing hole opened at the bottom front side of the jigsaw body. A limiting body is fixedly connected to the top of the protective shell on the side away from the jigsaw body. A rotating plate is fixedly connected to both the left and right sides of the top of the protective shell. A slider is rotatably connected between the two rotating plates. The outside of the slider is slidably connected to the fixing frame. The rear end of the fixing frame is fixedly connected to the jigsaw body. A limiting rod is provided above the fixing frame. The rear end of the limiting rod is fixedly connected to the jigsaw body.
[0011] Preferably, the limiting body includes a limiting frame, a rubber plate, a limiting ball, and a connecting plate. One side of the limiting frame is fixedly connected to the protective shell. A rubber plate is installed inside the limiting frame. The rubber plate has uniformly distributed deformation grooves. A connecting plate is provided on one side of the rubber plate. A limiting ball is fixedly connected to one side of the connecting plate. A slot is provided at the top of the limiting rod away from the jigsaw body.
[0012] Preferably, the limiting frame is located below the fixed frame, and the top of the protective shell has an installation groove corresponding to the fixed frame.
[0013] Compared with the prior art, the beneficial effects of this application are:
[0014] 1. In this application, by setting up a jigsaw body, base, slot, hole, support body and protective body, the base can be placed directly on the object to be cut, and then the jigsaw body can be started to cut the object. Before cutting, the saw blade of the jigsaw body is protected by the protective body, and the saw blade is prevented from causing injury to the operator. The support body can make the jigsaw body move more stably and move more during the cutting process.
[0015] 2. In this application, by configuring a base, slot, fixed shell, fixed plate, nut, vertical rod, limit spring, top plate, connecting block, rotating wheel, rubber block, insert, fixed block, pressure sensor, connecting plate, bolt, insert, and slot, the fixed shell can be installed inside the base when the insert penetrates the fixed plate and is inserted into the slot opened in the base. Then, the bolt and nut are threaded together to further fix the fixed plate, thus ensuring the fixed shell is stably installed above the base. This facilitates the installation and removal of the fixed shell and the maintenance of the guide body. The rotating wheel contacts the surface of the object being cut, making the movement of the jigsaw body more stable. The fixed position allows the jigsaw body to cut the object being cut. At this time, the limit spring can make the rotating wheel fit tightly against the surface of the object being cut through the top plate and the connecting block, which facilitates the rotation of the rotating wheel. The pressure sensor is tightly fitted to the top plate, and the pressure sensor transmits the pressure data to the controller of the jigsaw body. When the pressure sensor detects that the pressure is 0, the controller shuts down the jigsaw body to prevent the saw blade from continuing to run after leaving the object being cut, and to prevent the saw blade from injuring the operator after the cut is completed. At the same time, the rubber block fits tightly against the outside of the insert, which can quickly remove the connecting block and the rubber block from the outside of the insert, which is convenient for maintenance of the pressure sensor and the rotating wheel.
[0016] 3. In this application, the protective shell, limiting frame, rubber plate, deformation groove, limiting ball, connecting plate, rotating plate, fixed frame, slider, limiting rod, slot, connecting column, and rubber ring can protect the saw blade of the jigsaw body under the action of the protective shell, and at the same time prevent the saw blade from injuring the operator. When in use, the protective shell is pulled directly, and the protective shell drives the slider to slide in the fixed frame through the rotating plate. After rotating the protective shell 90°, the limiting frame set on the top of the protective shell is installed on the outside of the limiting rod. At this time, the rubber plate pushes the limiting ball into the slot opened in the limiting rod under its own elasticity, thereby limiting the fixed frame and the protective shell. The deformation groove can increase the deformation of the rubber plate, which facilitates the movement of the limiting ball. The connecting plate can install the limiting ball in the rubber plate. After the jigsaw is used up, the fixed shell is reset. At this time, the connecting column and rubber ring can position the protective shell to prevent the protective shell from being opened.

[0030] Please see Figure 1-12 This application provides a technical solution:
[0031] A smart protective jigsaw device includes a jigsaw body 1, a support body 5, and a protective body 6. A base 2 is rotatably connected to the bottom of the jigsaw body 1. A slot 3 is opened on the front side of the base 2, and the protective body 6 is installed in the slot 3. The top of the protective body 6 is connected to the jigsaw body 1. Two support bodies 5 are installed on the outside of the base 2, arranged front to back. The bottom of the base 2 has evenly distributed holes and slots 4. One end of the support body 5 is placed in the hole or slot 4 of the base 2. With this configuration, the base 2 can be placed directly on the object to be cut, and then the jigsaw body 1 can be started to cut the object. Before cutting, the saw blade of the jigsaw body 1 is protected by the protective body 6, which prevents the saw blade from causing injury to the operator. The support body 5 makes the jigsaw body 1 move more stably and move more during the cutting process.
[0032] like Figure 1-7As shown, the support body 5 includes a fixed shell 51, a fixed plate 52, a nut 53, a vertical rod 54, a limiting spring 55, a guide body 56, a connecting plate 57, a bolt 58, and a plug 59. The guide body 56 is installed inside the fixed shell 51. A vertical rod 54 is fixedly connected inside the fixed shell 51, penetrating the guide body 56. A limiting spring 55 is provided at the top of the outer side of the vertical rod 54. Fixed plates 52 are fixedly connected to both the left and right sides of the fixed shell 51. The fixed plates 52 are arranged in pairs on the left and right sides of the base 2. A connecting plate 57 is provided at the bottom of one side of the fixed plate 52. A plug 59 is fixedly connected to the side of the connecting plate 57 near the fixed plate 52, penetrating the fixed plate 52. Slots 7 are evenly distributed on both the left and right sides of the base 2. The plug 59 is located on the slots 7 opened on the base 2. Within the slot 7, a bolt 58 is rotatably connected at the center of the connecting plate 57, penetrating the fixing plate 52 and the side wall of the base 2. A nut 53 is threaded onto the outer side of the bolt 58 away from the connecting plate 57, and the nut 53 is fixedly connected to the base 2. This arrangement allows the fixing shell 51 to be installed inside the base 2 when the insert block 59 is inserted through the fixing plate 52 into the slot 7. The threaded connection of the bolt 58 and nut 53 further secures the fixing plate 52, ensuring the fixing shell 51 is stably installed above the base 2. This facilitates the installation and removal of the fixing shell 51 and the maintenance of the guide body 56. The guide body 56 includes a top plate 561, a connecting block 562, a rotating wheel 563, a rubber block 564, an insert strip 565, and... The top plate 561 is set inside the fixed shell 51. Vertical rods 54 are evenly distributed and run through the top plate 561. Connecting blocks 562 are fixedly connected to the left and right sides of the bottom of the top plate 561. Two horizontally arranged and front-back distributed rotating wheels 563 are rotatably connected to the bottom of the connecting blocks 562. A rubber block 564 is installed inside the top of the connecting blocks 562. An insert 565 is set inside the rubber block 564. Evenly distributed fixing blocks 566 are fixedly connected to the top of the insert 565. The top of the fixing blocks 566 is fixedly connected to the top plate 561. The connecting blocks 562 are set in the slots 4 opened in the base 2. Two fixing plates 52 are respectively set on the left and right sides of the connecting blocks 562. Pressure sensors are fixedly connected to the left and right sides of the center of the top of the connecting blocks 562. The pressure sensor 567 is positioned so that its top is in contact with the top plate 561. This arrangement ensures that the rotating wheel 563 contacts the surface of the object being cut, making the movement of the jigsaw body 1 more stable and facilitating cutting. The limit spring 55, through the top plate 561 and connecting block 562, keeps the rotating wheel 563 in close contact with the surface of the object, facilitating its rotation. The pressure sensor 567, in close contact with the top plate 561, transmits pressure data to the controller of the jigsaw body 1. When the pressure sensor 567 detects zero pressure, the controller shuts off the jigsaw body 1, preventing the saw blade from continuing to operate after leaving the object and thus preventing injury to the operator after cutting.Meanwhile, the rubber block 564 fits tightly against the outside of the insert 565, allowing the connecting block 562 and the rubber block 564 to be quickly removed from the outside of the insert 565, facilitating maintenance of the pressure sensor 567 and the rotating wheel 563.
[0033] like Figure 1 , 2 As shown in Figures 8, 9, 10, 11, and 12, the protective body 6 includes a protective shell 61, a limiting body 62, a rotating plate 63, a fixing frame 64, a slider 65, a limiting rod 66, a connecting post 68, and a rubber ring 69. A connecting post 68 is fixedly connected to the top of the protective shell 61 on the side closest to the jigsaw body 1. A rubber ring 69 is installed on the outside of the connecting post 68. Both the connecting post 68 and the rubber ring 69 are located in fixing holes opened at the bottom front side of the jigsaw body 1. A limiting body 62 is fixedly connected to the top of the protective shell 61 on the side furthest from the jigsaw body 1. Rotating plates 63 are fixedly connected to both the left and right sides of the top of the protective shell 61. A slider 65 is rotatably connected between two rotating plates 63. The outer side of the slider 65 is slidably connected to the fixed frame 64. The rear end of the fixed frame 64 is fixedly connected to the jigsaw body 1. A limit rod 66 is provided above the fixed frame 64. The rear end of the limit rod 66 is fixedly connected to the jigsaw body 1. The limit body 62 includes a limit frame 621, a rubber plate 622, a limit ball 624, and a connecting plate 625. One side of the limit frame 621 is fixedly connected to the protective shell 61. The rubber plate 622 is installed inside the limit frame 621. The rubber plate 622 has evenly distributed deformation grooves 623. The connecting plate 625 is provided on one side of the rubber plate 622. A limiting ball 624 is fixedly connected to one side of the connecting plate 625. A slot 67 is provided at the top of the limiting rod 66 away from the jigsaw body 1. The limiting frame 621 is set below the fixed frame 64. The top of the protective shell 61 has a mounting groove corresponding to the fixed frame 64. Through this setting, the saw blade of the jigsaw body 1 can be protected by the protective shell 61, and the saw blade can be prevented from injuring the operator. In use, the protective shell 61 is pulled directly. The protective shell 61 drives the slider 65 to slide in the fixed frame 64 through the rotating plate 63. After that, the protective shell 61 is rotated 90° and then the protective shell 61 is closed. The top limiting frame 621 is installed on the outside of the limiting rod 66. At this time, the rubber plate 622 pushes the limiting ball 624 into the slot 67 opened in the limiting rod 66 under its own elasticity, thereby limiting the fixed frame 64 and the protective shell 61. The deformation groove 623 can increase the deformation of the rubber plate 622, which facilitates the movement of the limiting ball 624. The limiting ball 624 can be installed in the rubber plate 622 through the connecting plate 625. After the jigsaw is used, the fixed shell 51 is reset. At this time, the protective shell 61 can be positioned by the connecting column 68 and the rubber ring 69 to prevent the protective shell 61 from being opened.
[0034] Workflow: When using this intelligent protective jigsaw device, first connect the power supply, then turn on the power switch on the jigsaw body 1, and pull the protective shell 61 forward. At this time, the protective shell 61 drives the connecting post 68 and the rubber ring 69 away from the fixing hole opened in the jigsaw body 1. Simultaneously, the protective shell 61 drives the slider 65 to slide within the fixing frame 64 through the rotating plate 63. Then, rotate the protective shell 61 90°. At this time, the protective shell 61 drives the rotating plate 63 to rotate on both sides of the slider 65. Then push the protective shell 61 towards the jigsaw body 1. The protective shell 61 drives the slider 65 to slide within the fixing frame 64 through the rotating plate 63. Simultaneously, the protective shell 61 drives the limiting frame 621 to move to the outside of the limiting rod 66 until the limiting ball 624 moves to the limit rod 66. The top of the slot 67 is opened. At this time, the rubber plate 622, under its own elasticity, pushes the limiting ball 624 into the slot 67 opened by the limiting rod 66, thereby positioning the rubber plate 622 and the limiting frame 621 to prevent the protective shell 61 from moving. Then, the jigsaw body 1 can be started, and the base 2 is placed on the surface of the object to be cut. At this time, the rotating wheel 563 pushes the connecting block 562 to move upward. The connecting block 562 pushes the top plate 561 to move outside the vertical rod 54. At the same time, the limiting spring 55 is compressed. As the connecting block 562 pushes the top plate 561 upward, the top of the pressure sensor 567 comes into contact with the top plate 561. At this time, the pressure sensor 567 receives the pressure and transmits the pressure signal to the controller inside the jigsaw body 1. At this time, the controller controls the movement via pressure sensor 567, which then pushes the jigsaw body 1. The jigsaw body 1 moves the fixed shell 51 and connecting block 562 via the base 2. The rotating wheel 563 rolls on the surface of the object being cut, facilitating the movement of the jigsaw body 1. When the jigsaw body 1 moves upwards and the rotating wheel 563 can no longer contact the object being cut, the controller stops the jigsaw body 1. At this point, the start switch of the jigsaw body 1 needs to be pressed again to restart it. This prevents the jigsaw body 1 from spinning freely after leaving the object being cut, making its use safer. After use, turn off the power switch of the jigsaw body 1 and disconnect the power supply. Then, follow the reverse procedure to protect it. When the housing 61 is reset, the connecting post 68 and the rubber ring are inserted into the jigsaw body 1, limiting the position of the protective housing 61. When maintenance is required on the rotating wheel 563 and the pressure sensor 567, the bolt 58 is rotated. The bolt 58 rotates within the connecting plate 57, and simultaneously, under the action of the nut 53, the connecting plate 57 gradually moves away from the fixed plate 52 until the bolt 58 and the nut 53 are no longer threaded. At this point, the insert block 59 can be removed from the slot 7 opened in the base 2. Then, the fixed housing 51 is moved upward, and the connecting block 562 is moved above the base 2. Afterward, the fixed housing 51 and the connecting block 562 are removed from between the jigsaw body 1 and the base 2. The connecting block 562 is pulled downward, causing the rubber block 564 to move away from the insert bar 565.Next, the rotating wheel 563 and pressure sensor 567 can be maintained. After maintenance, insert the insert 565 into the rubber block 564 of the connecting block 562. Then, install the connecting block 562 into the slot 4 of the base 2 in the reverse manner. Then, insert the insert 59 through the fixing plate 52 into the slot 7 of the base 2. The connecting plate 57 and the fixing plate 52 are positioned by the threaded connection of the bolt 58 and nut 53, thus completing the installation of the connecting block 562 and the fixing shell 51.
