Description

Technical Field

[0001] The utility model relates to the technical field of jigsaws, in particular to a jigsaw with high safety performance. Background Art

[0002] As a special tool designed for cutting complex curves, the jigsaw can accurately cut materials of various shapes with its flexible jigsaw blade and high-speed reciprocating teeth. It has a unique working principle. The motor drives the eccentric roller sleeve on the large gear through gear reduction, which in turn drives the reciprocating rod and saw blade to reciprocate. At the same time, the saw blade rotates at high speed to match this movement, allowing the saw teeth to continuously cut into the material surface and achieve efficient cutting.

[0003] The inventors of this application have found the following problems in practical use:

[0004] The saw blade of an existing jigsaw will generate heat due to friction during use, especially after long-term use or after sawing hard objects such as iron sheets, steel plates and other metals. The saw blade will be in a high temperature state. Therefore, the user's hands are easily burned when removing or replacing the saw blade after using the jigsaw. It takes a long time to wait for the saw blade to cool down before it can be replaced and used again, which affects the user experience. In addition, the high temperature during the sawing process may cause the saw blade to break, and the flying saw blade fragments may easily injure the user.

[0005] Therefore, it is necessary to provide a jigsaw with high safety performance to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the present invention is that the high temperature caused by frictional heat generated by the saw blade during use can burn the user, and the saw blade can break and splash and injure people.

[0033] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0034] like Figure 1-Figure 4 As shown, a jigsaw with high safety performance of the present invention includes a jigsaw body 1 and a spray mechanism 9. The spray mechanism 9 includes a housing 901. A water inlet 902 is provided on the top of the housing 901. The top of the water inlet 902 is rotatably connected to a cover plate 903 via a rubber strip. An air cylinder 904 is provided on one side of the water inlet 902. A piston 907 is slidably engaged inside the air cylinder 904. A pull rod 905 is provided on the top of the piston 907. A grip 906 is provided at one end of the pull rod 905. A through hole 908 is provided at the bottom of the air cylinder 904. A steel ball 909 is provided inside the through hole 908. The steel ball 909 is surrounded by locking teeth 910.

[0035] Water outlet pipes 911 are provided on both sides of the shell 901, and liquid valves 912 are provided on the water outlet pipes 911. A valve switch 913 is provided on one side of the liquid valve 912, and a nozzle 914 is provided at one end of the water outlet pipe 911. The water inlet 902 provided on the top of the shell 901 and the cover 903 rotatably connected by a rubber strip enable the user to easily inject water into the spray mechanism 9. The cover 903 can be tightly sealed to prevent water leakage. The air cylinder 904, the piston 907, the pull rod 905 and the grip 906 form a simple air pressure pump. The user can easily generate air pressure by holding and moving the grip 906 up and down, pushing the water mist to spray evenly through the water outlet pipe 911 and the nozzle 914, thereby improving the spraying efficiency and effect.

[0036] like Figure 1As shown, a finger groove 2 is provided on the outer surface of the jigsaw body 1, and a handle 3 is provided above the inner wall of the finger groove 2. The handle 3 is provided above the inner wall of the finger groove 2, providing a comfortable gripping position for the user, so that the user's hand can be naturally placed on the handle 3, reducing fatigue during long-term operation and improving operational comfort. Stable grip and comfortable operation help the user to better control the jigsaw and reduce safety accidents caused by improper operation. The finger groove 2 and the handle 3 provide the user with a stable gripping point, enhancing the user's sense of security during operation.

[0037] like Figure 1 As shown, a switch 5 is provided on one side of the handle 3, and a safety switch 4 is provided above the switch 5. The placement of the switch 5 on the side of the handle 3 allows the user to easily access and operate the switch 5 while holding the jig saw without adjusting their hand position or posture, thereby improving operational convenience and comfort. The provision of the safety switch 4 provides an additional layer of safety for the jig saw. Before starting the jig saw, the user must first engage the safety switch 4 before operating the switch 5 to start the saw. This helps prevent misoperation or accidental start-up, thereby enhancing product safety.

[0038] like Figure 1 As shown, a speed adjustment knob 6 is provided on the top of the jigsaw body 1, and a swing adjustment knob 7 is provided below the speed adjustment knob 6. The speed adjustment knob 6 allows the user to flexibly adjust the cutting speed of the jigsaw according to different cutting materials and cutting requirements, so that the jigsaw can adapt to more types of cutting tasks, thereby improving its versatility and practicality. The swing adjustment knob 7 enables the user to accurately control the swing amplitude of the jigsaw during the cutting process, thereby improving cutting efficiency.

[0039] like Figure 1 、 Figure 2 As shown, a base plate 8 is provided at the bottom of the jigsaw body 1, and a saw blade 12 is provided inside the base plate 8. The base plate 8 provides a stable support platform for the saw blade 12, ensuring that the saw blade 12 can maintain a stable motion trajectory during the cutting process, thereby improving the cutting accuracy and stability. The base plate 8 plays a certain protective role on the saw blade 12, which can reduce the external force impact and wear on the saw blade 12 during the cutting process, thereby extending the service life of the saw blade 12.

[0040] like Figure 1As shown, a support block 13 is provided on the top of the base plate 8, and the support block 13 is adapted to the water outlet pipe 911. The support block 13 provides a stable support point for the water outlet pipe 911, ensuring that the water outlet pipe 911 will not move or fall off due to vibration or external force when spraying water mist, thereby ensuring the stability and reliability of the spray mechanism 9. The support block 13 is adapted to the water outlet pipe 911, so that the water outlet pipe 911 can be accurately positioned on the base plate 8, ensuring that the water mist can be accurately sprayed onto the saw blade 12, thereby improving the cooling and lubrication effects.

[0041] like Figure 1 、 Figure 2 As shown, a light battery box 10 is provided under the housing 901, and an LED lamp 11 is provided at the bottom of the light battery box 10. The LED lamp 11 can provide clear lighting for the user, especially in a dark environment, so that the user can observe the cutting position more accurately, thereby improving the cutting accuracy and overall work quality. The good lighting conditions provided by the LED lamp 11 help the user to better identify the cutting area and the surrounding environment, reduce safety hazards during operation, and improve work safety.

[0042] like Figure 2 、 Figure 4 As shown, a light-transmitting plate 915 is provided on the outer surface of the housing 901, and a scale bar 916 is provided on one side of the light-transmitting plate 915. The light-transmitting plate 915 allows the user to clearly see the water level of the water tank inside the housing 901, thereby avoiding poor spraying effect due to insufficient water during the sawing process, thereby improving the overall use efficiency of the jigsaw. The scale bar 916 provides a clear water reference, and the user can know the remaining water in the water tank at any time to ensure that the spray mechanism 9 has enough water for use.

[0043] During implementation, first, the user adjusts the speed and rocking degree of the saw blade through the speed adjustment knob 6 and the rocking adjustment knob 7 as needed, and then the user drives the piston 907 to slide in the air cylinder 904 by pulling the grip 906 up and down, thereby compressing the air in the air cylinder 904. When pressing down, the through hole 908 at the bottom of the air cylinder 904 is opened, and the high-pressure air enters the water cavity inside the shell 901 through the through hole 908, pressurizing the water tank. The steel ball 909 in the through hole 908 and the surrounding latch teeth 910 ensure that the through hole 908 opens when the piston 907 is pressed down and closes when pulled up, preventing water backflow and pressure leakage. Then the user fixes the external saw blade and turns on the safety switch. The user can turn on one or two valve switches 913 as needed to spray water from the nozzle 914. Then the user holds the grip 3 tightly and presses the switch 5 to saw, and the LED light lights up to illuminate the cutting area.

[0044] If the user does not open the valve switch 913 when sawing, he can open the valve switch 913 after sawing to allow the saw blade to cool down quickly, making it easier to replace the saw blade and increasing the use efficiency. The user can observe the water level in the water tank in real time through the light-transmitting plate 915 and the scale bar 916 and add water in time.

[0045] The advantages of this technical solution in practical applications include but are not limited to the following:

[0046] 1. Spray mechanism: The spray mechanism can cool down and lubricate the saw blade in time during or after sawing, effectively reducing the high temperature and wear of the saw blade caused by friction;

[0047] 2. The light-transmitting plate and scale bar enable users to observe the water level in the water tank in real time to ensure that there is enough water for the sprinkler system.
