[0027] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] Combination Figure 1 and Figure 3 As shown, an environmentally friendly building construction cutting device includes a base 1. The base 1 has a flat rectangular structure. In order to improve the stability of the support, rubber pads are provided at the four corners of the lower end of the base 1. The upper end of the base 1 is fixedly connected to a driving motor 10, which is a driving unit. The output end of the driving motor 10 is rotatably connected to a second support arm 14, that is, the second support arm 14 can rotate around the output end of the driving motor 10, but does not rotate with it. The other end of the second support arm 14 is rotatably connected to the first support arm 13. The rotating setting can change the angle between the first support arm 13 and the second support arm 14. Both ends of the first support arm 13 are provided with rotating shafts. If the rotating shaft is fixedly connected to the first support arm 13, the end of the second support arm 14 rotatably connected thereto is rotatably connected to the rotating shaft.

[0029] The output end of the driving motor 10 and the rotating shaft are both provided with pulleys 11, that is, the device is provided with three pulleys 11, and the output end of the driving motor 10 is fixedly connected to the pulleys 11, the rotating shaft and the pulleys 11 are rotatably connected, the adjacent pulleys 11 are provided with the same transmission belt 12, and the pulley 11 with two transmission belts 12 is provided, and the pulley 11 is located in the middle of the other two, which can be understood as consisting of two edge pulleys, and the tool 7 is rotatably connected to the rotating shaft away from the driving motor 10, and the tool 7 is fixedly connected to the adjacent pulley 11. Start the driving motor 10, and the tool 7 is driven to rotate through the pulley 11 and the transmission belt 12.

[0030] Furthermore, the transmission belt 12 here can be one of a V-belt, a synchronous belt, and a chain, and the type of the corresponding pulley 11 is changed according to the type of the transmission belt 12.

[0031] In the above, since the first support arm 13 and the second support arm 14 are rotatably arranged, the tool 7 at the end thereof has a larger range of movement, which can not only cut construction materials but also cut the construction site, such as cutting seams and digging grooves on the cement floor.

[0032] Combination Figure 1 and Figure 2 As shown, a second handle 9 is provided on one side of the cutter 7 for pulling and changing the moving track of the cutter 7. The lower part of the second handle 9 is rotatably connected to a rolling mechanism 6. A roller 63 is provided at the lower part of the rolling mechanism 6. The rolling mechanism 6 is used to provide support. If the cutter 7 is controlled only by the second handle 9, it is difficult to control the moving track of the cutter 7. At this time, the rolling mechanism 6 provides support, which is conducive to controlling the cutter 7 for cutting. In addition, when it is necessary to cut construction materials, such as bricks, during the cutting process, the roller 63 can be buckled on the bricks to fix the bricks and improve the quality of cutting.

[0033] Combination Figure 1 and Figure 4 As shown, a dirt collecting box 5 is provided on the middle side wall of the base 1. During the cutting process, it is used to store dust and reduce air pollution. The dirt collecting box 5 is a multi-section structure, and adjacent structures are slidably matched. The length of the dirt collecting box 5 is determined according to the moving range of the tool 7, and the dirt collecting box 5 needs to be cleaned when it is used and stored.

[0034] A water tank 3 is fixedly connected to the upper end of the base 1 for storing water. A water inlet is provided at the upper end of the water tank 3. A water pump is provided inside the water tank 3. A water pipe 4 is fixedly connected to the output end of the water pump, and the other end of the water pipe 4 extends to the tool 7. During the cutting process, the water pump works to transport the water in the water tank 3 to the tool 7 through the water pipe 4, which not only cools the tool 7 but also reduces the degree of dust diffusion in the control.

[0035] The first support arm 13 and the second support arm 14 are both provided with a protective shell 8 on the outside. The rotating parts are wrapped to increase the safety of the device. At the same time, the protective shell 8 is provided according to the shape of the first support arm 13 and the second support arm 14. A cover plate is also provided separately and movably on the upper part of the connection between the first support arm 13 and the second support arm 14. When the first support arm 13 and the second support arm 14 rotate relative to each other, the gap between the two can be covered as much as possible.

[0036] Furthermore, a plurality of fixing blocks are arranged on the protective shell 8, and the water pipe 4 is fixed on the fixing blocks.

[0037] like Figure 2 As shown, the second handle 9 includes a cross bar 91, and one end of the cross bar 91 is fixedly connected to the adjacent end of the rotating shaft, a gripping rod 93 is fixedly connected to the side wall of the cross bar 91, and the gripping rod 93 is in an "L" shape, and the gripping rod 93 includes a horizontal section and a vertical section, and the end of the vertical section is fixedly connected to the cross bar 91, and the horizontal section spans above the tool 7, and an anti-slip sleeve is provided on its surface.

[0038] The rolling mechanism 6 includes a rotating ring 611, which is rotatably sleeved on the cross bar 91 and limits the axial movement of the rotating ring 611 on the cross bar 91. The side wall of the rotating ring 611 is fixedly connected with a fixed rod 66. The lower side wall of the fixed rod 66 is provided with a thread, and a limiting nut 67 is provided at the threaded section of the fixed rod 66. The rotating limiting nut 67 is used to adjust its position on the fixed rod 66. The lower part of the fixed rod 66 is sleeved with a sleeve 61, and the sleeve 61 can move axially relative to the fixed rod 66. The maximum moving distance is that the sleeve 61 is against the limiting nut 67. Changing the position of the limiting nut 67 changes the movable distance between the sleeve 61 and the fixed rod 66. Further, this setting can control the cutting depth of the tool 7. The lower end of the sleeve 61 is fixedly connected with a connecting piece 62, and the roller 63 is rotatably set on the connecting piece 62. The connecting piece 62 is U-shaped, and the roller 63 is clamped on the inner side of the connecting piece 62.

[0039] A hole is provided in the middle of the upper end of the fixed rod 66, and a pin rod 610 is provided in the hole. The pin rod 610 can move axially in the hole. The lower side wall of the pin rod 610 is fixedly connected with a lever 69, and the lever rod 69 extends from a preset long hole in the side wall of the fixed rod 66. By setting the long hole, the lever rod 69 has space for movement, that is, the pin rod 610 can be moved up and down by the lever rod 69. A second spring 68 is provided at the lower end of the pin rod 610, and a through hole 92 is provided on the cross bar 91 along the vertical direction. When the pin rod 610 moves into the through hole 92, the rotation of the rotating ring 611 is restricted, thereby ensuring that the rolling mechanism 6 is fixed in position relative to the cross bar 91, and the pin rod 610 cooperates with the through hole 92 only under the action of the second spring 68 to keep the rolling mechanism 6 fixed in position.

[0040] Furthermore, the number of the through holes 92 can be multiple, the pin rod 610 cooperates with the through holes 92 at different positions, and the rolling mechanism 6 is limited to multiple positions.

[0041] A first spring 65 is disposed inside the sleeve 61, and the upper end of the first spring 65 abuts against the lower end surface of the fixing rod 66. The first spring 65 can keep the sleeve 61 away from the fixing rod 66, and the distance between the upper part of the sleeve 61 and the limiting thread 67 is the distance that the sleeve 61 can move.

[0042] The lower side wall of the fixed rod 66 is fixedly connected with a side block 64, and there is at least one side block 64. The inner wall of the sleeve 61 is provided with a slide groove, and the slide groove and the side block 64 cooperate with each other. This setting can prevent the sleeve 61 from rotating relative to the fixed rod 66.

[0043] like Figure 1 As shown, first handles 2 are fixedly connected to both sides of the base 1, and the second handles 2 are used as lifting devices.
