Description

Technical Field

[0001] This utility model relates to the field of circular saw applications, specifically to a circular saw bracket with an adjustable cutting angle. Background Technology

[0002] A circular saw stand is a device used to support and fix a circular saw, providing a stable support structure. The design of the stand allows the circular saw to be installed smoothly on the operating platform, ensuring stability and safety during operation. Some circular saw stands also have an adjustment function, which can adjust the height and angle according to actual needs to adapt to different working environments and operating requirements. A circular saw stand is an indispensable auxiliary tool in the operation of a circular saw.

[0003] Chinese patent CN207206612U discloses an energy-saving circular saw for woodworking, including a workbench with supports at the four corners below the workbench. Rectangular fixing plates are mounted on the two adjacent supports on the left side. Universal casters with brake pads are located at the bottom of the supports. The circular saw facilitates movement and operation through the use of universal casters and brake pads. A recycling bin and brush are included; after processing, the power is turned off, and the brush sweeps the wood chips into the recycling bin. Overall, this circular saw enables the recycling and reuse of wood, improving the quality of the working environment while protecting the environment, and is worthy of promotion.

[0004] During use, the angle of the circular saw is fixed and the circular saw and the support are perpendicular to each other. The angle of the circular saw cannot be directly adjusted when it is necessary to cut at an angle. This makes it difficult to push and make the inclined plate into contact with the circular saw at a uniform speed when cutting the plate at an angle, which affects the cutting effect and cutting efficiency in the actual cutting process. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable cutting angle circular saw bracket. By sliding the connecting plate along the slide rail, the position of the blade can be adjusted laterally. The vertical cutting of the blade can be adjusted by the lateral sliding. The cutting angle can be fully adjusted in both lateral cutting position and tilt angle to adapt to different cutting needs. The efficient adjustment can improve cutting efficiency and solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cutting angle circular saw bracket, including a fixed frame. Connecting plates are slidably arranged on both sides of the upper outer end of the fixed frame. Slide rails are arranged on both sides of the inner interior of the fixed frame, and the connecting plates are embedded in the slide rails and slidably connected to them. A connecting piece is arranged between the two connecting plates. Second connecting blocks are arranged on both sides of the connecting piece facing the connecting plates, and first connecting blocks are arranged on the second connecting blocks facing the connecting plates. The first connecting blocks and the second connecting blocks are rotatably connected. This rotatable connection between the second connecting blocks and the first connecting blocks allows for adaptation to different required cutting angles. When inclined cutting is required, or when a slanted cross-section is needed, the material can be processed efficiently. The slanted cross-section is also conveniently achieved when splicing materials at corners, improving the efficiency of the material and its use.

[0007] Preferably, a first extension bar is arranged around the upper end of the first connecting block with the first connecting block as the center. There are three first extension bars, and the included angle between the three first extension bars is 45 degrees. A second extension bar is arranged vertically at the upper end of the second connecting block. A second fixing rod is arranged through the second extension bar and one of the first extension bars. The reserved first extension bar can facilitate the corresponding rotation of the second extension bar, so that the second extension bar can directly correspond to the first extension bar with the corresponding tilt direction after the angle is adjusted by the rotation of the motor. After the angle is adjusted, it is convenient for the second fixing rod to pass through and fix.

[0008] Preferably, a nut is provided on one side of the second fixing rod, and the inside of the nut is engaged with the external thread of the second fixing rod. The second fixing rod can pass through and fix the second extension bar and the first extension bar respectively, and the second fixing rod can be fixed by rotating the nut outside the second fixing rod.

[0009] Preferably, a connecting tube is provided at the middle position of the upper end of the connecting plate, and a first fixing rod is provided at the upper end of the outer side of the connecting tube. The outer side of the first fixing rod is threaded with the inner side of the connecting tube. The reserved connecting tube allows the first fixing rod to rotate and be embedded. The first fixing rod can be embedded and fit against the fixing frame when rotated inside the connecting tube, thus fixing the connecting plate after the position is adjusted.

[0010] Preferably, the lower end of the connecting plate is recessed towards the fixed frame and a storage groove is provided inside the storage groove. A pressing piece is provided inside the storage groove. When the pressing piece does not need to be attached to the fixed frame and the connecting plate is slid laterally to adjust its position, the recessed storage groove can be used to store the pressing piece.

[0011] Preferably, the upper end of the pressing piece is rotatably connected to the lower end of the first fixing rod. The rotatable pressing piece can reduce the friction generated by the pressing piece contacting the fixing frame, increase the strength of the pressing piece contacting the fixing frame, and improve the stability of the fixing connecting plate and the cutting tool.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Before the motor is started and the cutter is driven to rotate to cut the sheet metal, the position of the cutter can be adjusted laterally by sliding the connecting plate along the slide rail. The vertical cutting of the cutter can be adjusted laterally by sliding the plate. Secondly, the motor and the cutter can be directly adjusted by rotating the second connecting block within the first connecting block to adjust the tilt angle. While adjusting the cutting position laterally, the appropriate tilt angle can be adjusted. The cutter can be pre-adjusted before contacting the sheet metal, which can adapt to different cutting and usage requirements. It can be adjusted efficiently, improving the efficiency and effect of sheet metal cutting. Attached Figure Description

[0025] Furthermore, slide rails 18 are provided on both sides inside the fixed frame 1, and the connecting plate 6 is embedded inside the slide rail 18 and slidably connected to the inside of the slide rail 18. During the process of the connecting plate 6 sliding laterally, the connecting plate 6 slides on the upper part of the outside of the fixed frame 1 while sliding inside the slide rail 18.

[0026] It is worth mentioning that a connecting piece 7 is provided between the two connecting plates 6. A cutter 2 is provided on the upper part of the connecting piece 7. A motor 3 is provided on one end of the cutter 2. The output shaft of the motor 3 is fixedly connected to the center of the cutter 2 by bolts. The cutter 2 can be rotated by the drive of the motor 3, and the rotation of the cutter 2 can contact the plate material transmitted at the lower end.

[0027] It is worth mentioning that the outer part of the motor 3 is fixedly connected to the upper end of the connecting piece 7 by bolts. The bolts facilitate the installation and disassembly of the motor 3. The outer wall of the motor 3 is provided with a first handle 4 facing upwards, and the first handle 4 is fixedly connected to the outer wall of the motor 3 by bolts. One end of the fixing frame 1 is provided with a second handle 5. The reserved second handle 5 and the first handle 4 facilitate the user's grip, and the connection of the first handle 4 also facilitates the adjustment of the angle of the motor 3.

[0028] To allow for tilting adjustment of the tool 2 angle, second connecting blocks 9 are provided on both sides of the connecting piece 7 facing the connecting plate 6, and the second connecting blocks 9 and the connecting plate 6 are integrally formed. Figure 3As shown, the second connecting block 9 is provided with the first connecting block 8 facing the connecting plate 6, and the first connecting block 8 and the connecting plate 6 are an integral structure. The first connecting block 8 and the second connecting block 9 are rotatably connected. The angle of the tool 2 can be adjusted by rotating the second connecting block 9 and the first connecting block 8 which are reserved between the connecting plate 6 and the connecting piece 7, so as to adapt to the cutting requirements of different angles.

[0029] The angle between the fixed first connecting block 8 and the second connecting block 9, such as Figure 6 As shown, a first extension strip 12 is arranged around the upper part of the first connecting block 8 with the first connecting block 8 as the center. The first extension strip 12 and the first connecting block 8 are an integral structure. There are three first extension strips 12, and the included angle between the three first extension strips 12 is 45 degrees, which can meet the requirements of inclined cutting of the board.

[0030] Furthermore, a second extension bar 13 is vertically provided at the upper end of the second connecting block 9, and the second extension bar 13 is welded and fixed to the second connecting block 9, such as... Figure 2 As shown, a second fixing rod 14 is provided through the second extension bar 13 and one of the first extension bars 12. The adjusted angle can be fixed by the second fixing rod 14 passing through the second extension bar 13 and the first extension bar 12 simultaneously.

[0031] In this embodiment, a nut 15 is provided on one side of the second fixing rod 14, and the inside of the nut 15 is threaded with the outside of the second fixing rod 14. After the second fixing rod 14 passes through, the nut 15 rotates to the outside of the second fixing rod 14, thereby fixing the second fixing rod 14, the second extension bar 13 and the first extension bar 12, so as to fix the cutting angle after adjustment.

[0032] In order to fix the position of the adjusted connecting plate 6, a connecting tube 11 is provided at the middle position of the upper end of the connecting plate 6. A first fixing rod 10 is provided at the upper end of the outside of the connecting tube 11, and the outside of the first fixing rod 10 is threaded with the inside of the connecting tube 11. Rotating the first fixing rod 10 inside the connecting tube 11 can make the first fixing rod 10 continuously embedded inside the connecting plate 6. The embedding of the first fixing rod 10 can squeeze the upper end of the outside of the fixing frame 1, and fix the position of the adjusted connecting plate 6 by tightly adhering to the fixing frame 1.

[0033] It is worth mentioning that, such as Figure 4 and Figure 5As shown, the lower end of the connecting plate 6 is recessed towards the fixing frame 1 and a storage groove 16 is provided. The storage groove 16 is provided with a pressing piece 17. The upper end of the pressing piece 17 is rotatably connected to the lower end of the first fixing rod 10. After the first fixing rod 10 is rotated and embedded in the connecting tube 11, the first fixing rod 10 will push the pressing piece 17, and the pressing piece 17 will replace the first fixing rod 10 to contact the fixing frame 1. The pressing piece 17 can expand the contact area with the fixing frame 1 and improve the stability when fixing the tool 2.

[0034] Working principle: When adjusting the angle using the circular saw bracket, the position of the blade 2 is adjusted according to the cutting position requirements. The connecting plate 6 slides laterally along the slide rail 18 outside the fixed frame 1 to adjust the cutting position of the blade 2. After adjustment, the first fixing rod 10 is rotated. The first fixing rod 10 is threaded inside the connecting tube 11, which can longitudinally push the pressing plate 17. The pressing plate 17 contacts the fixed frame 1 longitudinally from the storage groove 16, fixing the connecting plate 6 after the position adjustment. The blade 2 is fixed by fixing the connecting plate 6. The first handle 4 and the second handle 5 can be held by both hands respectively. By pushing the fixed frame 1 laterally, the blade 2 can be moved, allowing the blade 2 to rotate perpendicularly to the lower end. The plate is cut, and the cutting angle of the cutter 2 is adjusted with the second connecting block 9 as the center. The first handle 4 is held to drive the motor 3, the cutter 2, the connecting piece 7 and the second connecting block 9 to rotate inside the first connecting block 8. The rotation causes one of the first connecting blocks 8 to overlap with the second extension strip 13. The second fixing rod 14 passes through the first extension strip 12 and the second extension strip 13 respectively. The nut 15 is rotated and twisted outside the second fixing rod 14 to fix the angle of the cutter 2 after the angle is adjusted. After the angle is adjusted, the first handle 4 and the second handle 5 can be held by both hands respectively. By pushing the fixing frame 1 to move the cutter 2 laterally, the cutter 2 can be rotated and tilted to cut the plate that is in contact with the lower end.
