[0045] Please combine Figure 3 Furthermore, the tool holder 100 includes a mounting seat 1003 and a fixing seat 1001 , the mounting seat 1003 is movably connected to the fixing seat 1001 , and the mounting seat 1003 is used to install the cutting tool 11 .
[0046] It can be understood that the mounting seat 1003 and the fixing seat 1001 are movably connected, which means that the mounting seat 1003 can be moved relative to the fixing seat 1001, so that the position of the blade 113 can also be adjusted by the movement of the mounting seat 1003.
[0047] In this embodiment, the mounting seat 1003 is arranged on the bottom side of the fixing seat 1001. Of course, in other embodiments, the mounting seat 1003 can also be arranged on the bottom side, front side and upper side of the fixing seat 1001. The front side is the side of the fixing seat 1001 away from the main frame 13. The specific setting is not limited, and it is only necessary to realize that the cutting tool 11 can cut the grass on the front side.

[0049] Furthermore, a slide rail mechanism is provided in the fixing seat 1001 , an opening 1002 is provided on one side of the fixing seat 1001 facing the mounting seat 1003 , a connecting rod 1004 is provided on the mounting seat 1003 , and the connecting rod 1004 passes through the opening 1002 and is connected to the slide rail mechanism.
[0050] It can be understood that the slide rail mechanism may specifically include a slide rail and a motor, and the connecting rod 1004 is connected to the slide rail to move left and right.
[0051] Please combine Figure 4 Furthermore, the cutting tool 11 includes a support 111, a fixing member 112 and a blade 113, the fixing member 112 is connected to the support 111, the two blades 113 are detachably connected to the fixing member 112, and the blades 113 can rotate relative to the support 111, and the support 111 is connected to the tool holder 100.
[0052] It can be understood that in this embodiment, two blades 113 are provided on the cutting tool 11, wherein the blades 113 are detachably mounted on the fixing member 112, so that the operator can replace different blades 113 for cutting according to the specific terrain and environment characteristics. In addition, by providing two blades 113, the purpose of efficient and fast cutting can be achieved. In addition, the blade close to the support member 111 is defined as the first blade, and the other blade is defined as the second blade. The diameter of the circle formed when the second blade rotates is smaller than the diameter of the circle formed when the first blade rotates. Since the diameter of the second blade is smaller when it is cutting and rotating, especially for uneven terrain, the second blade can directly enter the concave ground for cutting, which greatly improves the use environment restrictions of the cutting machine 1, so that it can also be used in complex terrain.
[0053] Please further combine Figure 3 In some embodiments, at least two cutting tools 11 are installed on the tool holder 10 , and a plurality of the cutting tools 11 are installed in a row on the tool holder 10 .
[0054] It can be understood that in order to achieve large-scale grass cutting, multiple cutting tools 11 can be installed to increase the cutting area and improve the overall cutting efficiency. The row arrangement is mainly to achieve neat cutting of the grass during cutting.
[0055] Specifically, the cutting knives 11 are arranged in two rows, and the cutting knives 11 in one row are arranged corresponding to the intervals between the cutting knives 11 in the other row.
[0056] It can be understood that in order to prevent collision and other wear between the cutting tools 11 in the same row, gaps are left between the cutting tools 11 in the same row, resulting in that the grass in the gaps between the cutting tools 11 will not be cut during cutting, and the blades 113 need to be repeatedly translated to achieve complete cutting. By setting two rows of cutting tools 11, the rear row can directly cut the grass that has not been cut by the front row when the cutting machine 1 moves, without the need to translate the blades 113 multiple times, which greatly saves working time and greatly improves efficiency.
[0057] In summary, compared with the prior art, the cutting machine tool holder 10 and the cutting machine 1 provided by the present invention have the following advantages:
[0058] The embodiment of the utility model provides a cutting machine tool holder 10, wherein a cutting tool 11 is mounted on the tool holder 10, and the tool holder 10 is connected to a main frame 13 via a support member 111, wherein the tool holder 10 is moved up and down by a driving arm 102, so as to adjust the height of the cutting tool 11 thereon. Specifically, one end of the driving arm 102 is directly connected to a wheel 12, and when the driving arm 102 drives the support member 111 to lift upward, the force is mainly borne by the wheel 12, and the impact on the frame is relatively small. Furthermore, since the driving arm 102 is not arranged at the bottom of the main frame 13, it is not easily affected by complex terrain.
