[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-2 This utility model provides a technical solution: an adjustable angle cutting device for processing steel wire troughs and cable trays, including a base 1, a supporting component 2 is provided at the middle position of the top surface of the base 1, a limiting component 3 is provided at the movable end of the supporting component 2, a cutting component 4 is provided above the limiting component 3; an adjusting component 5 is provided above the cutting component 4, and one end of the adjusting component 5 is connected to one side of the top surface of the base 1, and a control switch group 6 is provided on one side of the top surface of the base 1;

[0031] The base 1 allows for stable placement in the designated location and provides stable support for the lifting component 2, adjusting component 5, and control switch group 6. The limiting component 3 clamps and positions steel cable trays and other components, and stably mounts them on top of the lifting component 2. The flexible rotation and adjustment of the lifting component 2 allows for flexible adjustment of the left and right positions of the steel cable trays and other components on the limiting component 3. This facilitates the cutting component 4 in cutting the steel cable trays and other components. The adjusting component 5 allows for the installation of the cutting component 4 and flexible adjustment of its position, height, and cutting angle. This enables workers to flexibly cut steel cable trays and other components from multiple angles according to their needs, thereby improving the efficiency and convenience of cutting and processing steel cable trays and other components.

[0032] See Figures 1-3 The lifting assembly 2 includes a first U-shaped frame 21. A movable block 22 is provided within the inner cavity of the first U-shaped frame 21. A first screw hole 23 is provided through the side wall of the movable block 22. A first screw 24 is rotatably mounted within the inner cavity of the first screw hole 23, and both ends of the first screw 24 are connected to the two side walls of the inner cavity of the first U-shaped frame 21 via ball bearings. A support plate 25 is provided on the top surface of the movable block 22. A first bevel gear 26 is provided at one end of the first screw 24 and on the outside of the first U-shaped frame 21. A second bevel gear 27 meshes with one side of the first bevel gear 26, and a middle section of the second bevel gear 27 is provided with… There is a shaft 28, the middle part of which is connected to the top surface of the base 1 through a first bearing 29. One end of the shaft 28 is connected to a first handwheel 210. Wheels 211 are provided on both sides of the bottom surface of the moving block 22, and the bottom of the wheels 211 is in rolling contact with the bottom surface of the inner cavity of the first U-shaped frame 21. An electromagnet 212 is provided in the middle of the bottom surface of the moving block 22. A groove 213 is provided in the middle of the top surface of the first U-shaped frame 21. An iron strip 214 is provided in the inner cavity of the groove 213, and the bottom of the electromagnet 212 is in contact with the top surface of the iron strip 214.

[0033] By supporting the first U-shaped frame 21 in component 2, it can be fixed to the top surface of the base 1, and the first screw 24 can be installed through two ball bearings. The moving block 22 can be rotatably connected to the first screw 24 through the first screw hole 23, and can also provide stable support for the limiting component 3 through the support plate 25. Then, by rotating the first handwheel 210, the shaft 28 located on the first seated bearing 29 can be smoothly rotated. Since one end of the shaft 28 meshes with the first bevel gear 26 at one end of the first screw 24 through the second bevel gear 27, the first screw 24 can be rotated synchronously when the first handwheel 210 rotates. The movable block 22 located on the first screw 24 can be adjusted to the left and right. Since wheels 211 are provided on both sides of the bottom surface of the movable block 22, the friction between the bottom of the movable block 22 and the bottom surface of the inner cavity of the first U-shaped frame 21 can be reduced, which makes it easier for the staff to adjust the position of the movable block 22. When the movable block 22 is adjusted to the designated position, the electromagnet 212 can be turned on by controlling the switch group 6, so that the electromagnet 212 can magnetically attract the iron bar 214 in the inner cavity of the groove 213, thereby limiting the movable block 22 so as to prevent the limiting component 3 from shaking left and right with the steel wire trough, cable tray and other components.

[0034] See Figures 1-4 The limiting component 3 includes a second U-shaped frame 31. A second screw hole 32 is provided on one side wall of the second U-shaped frame 31. A second screw 33 is rotatably installed in the inner cavity of the second screw hole 32. A second handwheel 34 is provided at one end of the second screw 33 and located outside the second U-shaped frame 31. A top plate 35 is provided at one end of the second screw 33 and located inside the second U-shaped frame 31.

[0035] The second U-shaped frame 31 in the limiting component 3 can be installed on the top surface of the support plate 25, and the second screw 33 can be rotated and installed through the second screw hole 32. Then, by rotating the second handwheel 34, the second screw 33 can be rotated synchronously on the second screw hole 32, so that the other end of the second screw 33 can abut against the side wall of the steel cable tray, cable rack and other components located in the inner cavity of the second U-shaped frame 31 through the top plate 35, thereby limiting the steel cable tray, cable rack and other components, so that the cutting component 4 can cut the steel cable tray, cable rack and other components.

[0036] See Figure 1 , Figure 2 and Figure 5 The cutting assembly 4 includes a fixed frame 41, the top surface of which is connected to the output end of the adjustment assembly 5, and a motor 42 is provided in the inner cavity of the fixed frame 41. A cutting blade 43 is installed at the output end of the motor 42.

[0037] The fixing bracket 41 in the cutting assembly 4 can be installed at the output end of the adjusting assembly 5 and can also be used to install and fix the motor 42. Then, the electric cutting blade 43 can be operated by the motor 42, so that the cutting blade 43 can easily cut steel wire troughs, cable trays and other components.

[0038] See Figure 1 , Figure 2 , Figure 5 and Figure 6 The adjustment component 5 includes a stabilizing frame 51, the bottom end of which is connected to the top surface of the base 1, and a positioning plate 52 is fixedly installed at the top of the stabilizing frame 51. A second bearing 53 is provided at the lower middle part of the outer wall of the positioning plate 52. An electric push rod 54 is provided in the inner cavity of the second bearing 53. The telescopic end of the electric push rod 54 is connected to the top surface of the fixed frame 41 through a connecting plate 55. A rotating part 56 is provided on the electric push rod 54 near the top. One side of the rotating part 56 is connected to the positioning plate 52.

[0039] By adjusting the stabilizing bracket 51 in component 5, it can be installed on one side of the top surface of the base 1, and the second seated bearing 53 and the rotating part 56 can be installed and fixed via the positioning plate 52. Then, the electric push rod 54 can be installed and fixed via the second seated bearing 53, and the electric push rod 54 can be rotated flexibly. The electric push rod 54 can drive the fixing bracket 41 to move up and down via the connecting plate 55, which facilitates the cutting blade 43 on the motor 42 to cut steel wire troughs, cable trays and other components. Since one side of the rotating part 56 is installed on the electric push rod 54 and is close to the top, the rotating part 56 can flexibly drive the electric push rod 54 to rotate, and lock and position the rotated electric push rod 54. This allows the orientation of the motor 42 located at the bottom of the electric push rod 54 to be adjusted so that the cutting blade 43 on the motor 42 can cut steel wire troughs, cable trays and other components at multiple angles.

[0040] See Figure 6 , Figure 7 The rotating part 56 includes a first retaining ring 561 and a second retaining ring 562 disposed on the electric push rod 54, wherein the second retaining ring 562 is located above the first retaining ring 561, and one side of the outer wall of the second retaining ring 562 is connected to the positioning plate 52 through a crossbar 563; a handle 564 is disposed on one side of the outer wall of the first retaining ring 561, a vertical plate 565 is disposed on one side of the top surface of the handle 564, and a third screw hole 566 is provided on the side wall of the vertical plate 565 near the top end, and a locking button 567 is rotatably installed in the inner cavity of the third screw hole 566; a groove 568 for engaging one end of the locking button 567 is provided on the outer wall of the second retaining ring 562, and an angle mark 569 is provided on the top end of the second retaining ring 562;

[0041] The first retaining ring 561 in the rotating part 56 can be fixedly installed on the electric push rod 54 and also provides an attachment base for the handle 564. The second retaining ring 562 can be movably sleeved on the electric push rod 54 and connected to the positioning plate 52 via the crossbar 563. By turning the handle 564, the electric push rod 54 can be driven to rotate on the second bearing 53 via the first retaining ring 561, and at the same time, the electric push rod 54 can also rotate in the inner cavity of the second retaining ring 562. The upright plate 565 can fix it to one side of the top surface of the handle 564. It can also be installed by rotating the locking button 567 through the third screw hole 566. Through the locking button 567, one end of it can be inserted into the inner cavity of the slot 568 located outside the second retaining ring 562, thereby locking and limiting the position of the adjusted handle 564, so as to fix the orientation of the motor 42 and make the motor 42 drive the cutting blade 43 to cut more smoothly. Since the top ring of the second retaining ring 562 is provided with an angle mark 569, it is convenient for the staff to check the angle of the handle 564, thereby making it convenient for the staff to cut at a precise angle.

[0042] During operation, the base 1 allows for stable placement in the designated position and provides stable support for the lifting component 2, adjusting component 5, and control switch group 6. The limiting component 3 clamps and positions steel cable trays and other components, and stably mounts them on top of the lifting component 2. The flexible rotation and adjustment of the lifting component 2 allows for flexible adjustment of the left and right positions of the steel cable trays and other components on the limiting component 3, facilitating the cutting component 4 to cut the steel cable trays and other components. The adjusting component 5 allows for the installation of the cutting component 4 and flexible adjustment of its position, height, and cutting angle, enabling workers to flexibly cut steel cable trays and other components at multiple angles according to their needs, thereby improving the efficiency and convenience of cutting and processing steel cable trays and other components.

[0043] By supporting the first U-shaped frame 21 in component 2, it can be fixed to the top surface of the base 1, and the first screw 24 can be installed through two ball bearings. The moving block 22 can be rotatably connected to the first screw 24 through the first screw hole 23, and can also provide stable support for the limiting component 3 through the support plate 25. Then, by rotating the first handwheel 210, the shaft 28 located on the first seated bearing 29 can be smoothly rotated. Since one end of the shaft 28 meshes with the first bevel gear 26 at one end of the first screw 24 through the second bevel gear 27, the first screw 24 can be rotated synchronously when the first handwheel 210 rotates. The movable block 22 located on the first screw 24 can be adjusted to the left and right. Since wheels 211 are provided on both sides of the bottom surface of the movable block 22, the friction between the bottom of the movable block 22 and the bottom surface of the inner cavity of the first U-shaped frame 21 can be reduced, which makes it easier for the staff to adjust the position of the movable block 22. When the movable block 22 is adjusted to the designated position, the electromagnet 212 can be turned on by controlling the switch group 6, so that the electromagnet 212 can magnetically attract the iron bar 214 in the inner cavity of the groove 213, thereby limiting the movable block 22 so as to prevent the limiting component 3 from shaking left and right with the steel wire trough, cable tray and other components.

[0044] The second U-shaped frame 31 in the limiting component 3 can be installed on the top surface of the support plate 25, and the second screw 33 can be rotated and installed through the second screw hole 32. Then, by rotating the second handwheel 34, the second screw 33 can be rotated synchronously on the second screw hole 32, so that the other end of the second screw 33 can abut against the side wall of the steel cable tray, cable rack and other components located in the inner cavity of the second U-shaped frame 31 through the top plate 35, thereby limiting the steel cable tray, cable rack and other components, so that the cutting component 4 can cut the steel cable tray, cable rack and other components.

[0045] The fixing bracket 41 in the cutting assembly 4 can be installed at the output end of the adjusting assembly 5 and can also be used to install and fix the motor 42. Then, the electric cutting blade 43 can be operated by the motor 42, so that the cutting blade 43 can easily cut steel wire troughs, cable trays and other components.

[0046] By adjusting the stabilizing bracket 51 in component 5, it can be installed on one side of the top surface of the base 1, and the second seated bearing 53 and the rotating part 56 can be installed and fixed via the positioning plate 52. Then, the electric push rod 54 can be installed and fixed via the second seated bearing 53, and the electric push rod 54 can be rotated flexibly. The electric push rod 54 can drive the fixing bracket 41 to move up and down via the connecting plate 55, which facilitates the cutting blade 43 on the motor 42 to cut steel wire troughs, cable trays and other components. Since one side of the rotating part 56 is installed on the electric push rod 54 and is close to the top, the rotating part 56 can flexibly drive the electric push rod 54 to rotate, and lock and position the rotated electric push rod 54. This allows the orientation of the motor 42 located at the bottom of the electric push rod 54 to be adjusted so that the cutting blade 43 on the motor 42 can cut steel wire troughs, cable trays and other components at multiple angles.

[0047] The first retaining ring 561 in the rotating part 56 can be fixedly installed on the electric push rod 54 and also provides an attachment base for the handle 564. The second retaining ring 562 can be movably sleeved on the electric push rod 54 and connected to the positioning plate 52 via the crossbar 563. By turning the handle 564, the electric push rod 54 can be driven to rotate on the second bearing 53 via the first retaining ring 561, and at the same time, the electric push rod 54 can also rotate in the inner cavity of the second retaining ring 562. The upright plate 565 can fix it to one side of the top surface of the handle 564. It can also be installed by rotating the locking button 567 through the third screw hole 566. Through the locking button 567, one end of it can be inserted into the inner cavity of the slot 568 located outside the second retaining ring 562, thereby locking and limiting the position of the adjusted handle 564, so as to fix the orientation of the motor 42 and make the motor 42 drive the cutting blade 43 to cut more smoothly. Since the top ring of the second retaining ring 562 is provided with an angle mark 569, it is convenient for the staff to check the angle of the handle 564, thereby making it convenient for the staff to cut at a precise angle.

[0048] In summary, this device can flexibly adjust the position of the workpiece and perform multi-angle cutting, thereby improving the convenience of workpiece cutting and processing.
