[0002] A jigsaw is a sawing machine that can be used to cut materials such as wood, plastic, and aluminum alloy in a curved shape. Compared with other sawing machines, a jigsaw can perform curved cutting more precisely without damaging the curved shape of the material. A jigsaw is usually used in the manufacturing process of furniture, woodcrafts, toys, carvings, etc. that require complex curves. Compared with manual carving or other methods, a jigsaw can greatly improve production efficiency and accuracy, and at the same time reduce the physical labor intensity of workers.

[0003] When operating a jigsaw, since the jigsaw and the saw blade are assembled and installed, when the jigsaw needs to be used, the saw blade needs to be taken out, then placed in the placement groove, and the screws are tightened. This installation method is inefficient. Repeated screwing of the screws over a long period of time will cause damage to the screws, and the saw blade may fall off during the cutting process, endangering personal safety. Therefore, this application proposes an adjustable-angle saw blade installation structure for a jigsaw. Summary of the Utility Model

[0004] The purpose of the utility model is to address the problem of screw damage caused by repeated installation in the background technique, and propose an adjustable-angle saw blade installation structure for a jigsaw.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] 1. By pressing the pressing blocks at both ends of the mounting block, the pressing blocks drive the pressing plate to move downward. The two sides of the pressing plate squeeze the cutting surfaces of the guiding blocks, causing the guiding blocks to move towards both sides of the mounting block. The guiding blocks drive the sliding plate to move outwards. The sliding plate drives the fixing tube on one side of the limiting plate to separate from the fixing column. At the same time, the fixing tube moves out of the fixing hole, canceling the fixation of the saw blade. Place a new saw blade in the placement groove, release the pressing block, and the first spring rebounds to drive the fixing tube to insert into the fixing hole.

[0026] Among them, an adjusting mechanism is arranged on one side of the mounting post 1 for adjusting the rotation angle of the saw blade 2 to adapt to different cutting angles.

[0027] As Figures 5-6As shown in the figure, the auxiliary mechanism in this embodiment further includes sliding plates 5 slidably mounted on both sides of the mounting block 4. A connecting column 14 is fixedly mounted at the bottom of the sliding plate 5. One end of the connecting column 14 passing through the mounting cavity 3 is fixedly mounted with a limiting plate 16. A first spring 13 is sleeved on the limiting plate 16. One end of the first spring 13 is fixedly connected to the mounting cavity 3. A fixed tube 12 is fixedly mounted on one side of the limiting plate 16, and a fixed column 15 is fixedly mounted on the other side of the limiting plate 16. One end of the fixed column 15 is located inside the fixed tube 12. A fixing hole 7 is formed in the saw blade 2, and the fixed tube 12 is located inside the fixing hole 7. One side of both ends of the sliding plate 5 is fixedly mounted with a guiding block 18. The middle of the guiding block 18 is provided with a cut surface. A connecting shaft 9 is slidably mounted on the mounting block 4. A pressing plate 8 is fixedly mounted on the connecting shaft 9. Both ends of the pressing plate 8 are provided with cut surfaces. Both ends of the pressing plate 8 are in contact with the guiding block 18. A pressing block 10 is fixedly mounted on the top of the connecting shaft 9. When the saw blade 2 needs to be replaced, press the pressing block 10. The pressing block 10 drives the pressing plate 8 to move downward. As the pressing plate 8 continuously descends, the pressing plate 8 squeezes the cut surface of the guiding block 18, driving the guiding block 18 to move towards both sides of the mounting block 4. The guiding block 18 drives the sliding plate 5 to move outwards. The sliding plate 5 drives the fixed tube 12 and the fixed column 15 at one end of the limiting plate 16 to separate. At the same time, the fixed tube 12 is pulled out of the fixing hole 7 on the saw blade 2. At this time, pulling the saw blade 2 can extract it. Place the undamaged saw blade 2 into the placement groove 17, release the pressing block 10, and the first spring 13 rebounds after being compressed and deformed, driving the sliding plate 5 to move inwards. The fixed tubes 12 on both sides come into contact with the fixed column 15, and the fixed column 15 enters the fixed tube 12, and the fixed tube 12 enters the fixing hole 7, then the saw blade 2 can be fixed.

[0028] As Figures 2-3 shown in the figure, the adjusting mechanism is further included in this embodiment. The adjusting mechanism includes a connecting block 20 fixedly mounted on one side of the mounting column 1. An insertion socket 19 is formed in the connecting block 20. A support plate 25 is fixedly mounted on one side of the mounting block 4. The connecting block 20 is hinged to the support plate 25. A blocking block 24 is slidably mounted on one side of the mounting column 1. A plurality of through holes 22 arranged in an equidistant circular pattern are formed in the support plate 25. A fixing rod 21 is fixedly mounted at the bottom of the blocking block 24. One end of the fixing rod 21 is located inside the insertion socket 19 and the through hole 22. A guiding column 27 is fixedly mounted on the blocking block 24. A guiding plate 26 is fixedly mounted on one side of the mounting column 1. The guiding plate 26 is slidably connected to the guiding column 27. When the angle of the saw blade 2 needs to be adjusted, pull up the pulling plate 6. The pulling plate 6 pulls out the fixing rod 21 from the insertion socket 19 and the through hole 22, rotate the mounting block 4 to adjust the angle, and then release the pulling plate 6.

[0029] As Figures 2-5As shown in the figure, a second spring 11 is fixedly installed between the pressing plate 8 and the mounting block 4. One end of the second spring 11 is fixedly connected to the pressing plate 8. When the pressing block 10 is pressed, the second spring 11 rebounds and drives the pressing plate 8 to move upward, canceling the limit on the guiding block 18. A pulling plate 6 is fixedly installed at the top of the guiding column 27, and a third spring 23 is sleeved on the guiding column 27. One end of the third spring 23 is fixedly connected to the guiding plate 26.

[0030] Working principle: When it is necessary to install or replace the saw blade 2, press the pressing block 10. The pressing block 10 drives the pressing plate 8 to move downward. As the pressing plate 8 continues to descend, the pressing plate 8 squeezes the cutting surface of the guiding block 18, driving the guiding block 18 to move to both sides of the mounting block 4. The guiding block 18 drives the sliding plate 5 to move outward. The sliding plate 5 drives the fixing tube 12 at one end of the limiting plate 16 to separate from the fixing column 15. At the same time, the fixing tube 12 is pulled out of the fixing hole 7 on the saw blade 2. At this time, pulling the saw blade 2 can extract it. Place the undamaged saw blade 2 into the placement groove 17, release the pressing block 10, and the first spring 13 rebounds after being compressed and deformed, driving the sliding plate 5 to move inward. The fixing tubes 12 on both sides come into contact with the fixing columns 15, and the fixing columns 15 enter the fixing tubes 12. The fixing tubes 12 enter the fixing holes 7, and then the saw blade 2 can be fixed. When it is necessary to adjust the cutting angle of the saw blade 2, pull the pulling plate 6 upward. The pulling plate 6 pulls out the fixing rod 21 from the socket 19 and the through hole 22, rotate the mounting block 4 to adjust the angle, release the pulling plate 6, and the third spring 23 rebounds after being deformed, driving the fixing rod 21 to insert into the socket 19 and the through hole 22 to fix the mounting block 4. It realizes the rapid installation and replacement of the saw blade, and can arbitrarily adjust the cutting angle of the saw blade, improving the cutting accuracy, with simple operation and convenient use.
