DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] As attached Figure 1 To Attachment Figure 3 As shown: a new type of tobacco seedling leaf cutter, including a triangular bracket 1, characterized in that a lower fixing rod 2 is respectively arranged at the lower end of the inner wall and the middle end of the inner wall of the triangular bracket 1 in the horizontal direction, and a side railing 21 is respectively arranged at the left and right sides of the front side of the lower fixing rod 2 in the vertical direction, and a bottom supporting rod 22 is arranged below the side railing 21 in the horizontal direction, and the bottom supporting rod 22 is connected to the bottom end surface of the lower fixing rod 2, and the top part of the bottom supporting rod 22 is also arranged opposite to the inner end of the side railing 21. In this way, when in use, the two side rails 21 and the one bottom supporting rod 22 can be combined into a concave or U-shaped supporting frame. Through this frame, the tobacco seedling tray can be stably placed on the side railings 21 and the bottom supporting rod 22, which helps to maintain sufficient efficiency and stability when trimming the tobacco leaves in the later stage.

[0027] At the same time, a connecting rod 3 is fixedly provided at the left end of the bottom front side and the right end of the bottom front side of the tripod bracket 1, and the connecting rod 3 includes a first connecting rod 3 and a second connecting rod 3. The first connecting rod 3 and the second connecting rod 3 are both rotatably provided with an I-shaped work wire drum 31 along the outer surface, and the work wire drum 31 is located in front of the side railing 21 and the bottom support rod 22, and a hanger 32 is fixedly provided on the inner end surface of the work wire drum 31. The hanger 32 is specifically a small metal hard hook, and then a rubber band 34 is tied to the hanger 32, so that one end of the rubber band 34 can be fixed on the hanger 32, and the rubber band 34 can also be stretched by the work wire drum 31. After stretching, the tightness of the rubber band 34 can be increased, which helps to obtain stronger power during ejection.

[0028] In addition, a wire 36 is horizontally arranged at the front side of the side railing 21 and the bottom support rod 22, and the left and right ends of the wire 36 are connected to the rubber band 34. During installation, one end of the wire 36 is connected to the rubber band 34 on the first connecting rod 3, and the other end of the wire 36 is connected to the rubber band 34 on the second connecting rod 3. When the iron wire 36 and the rubber band 34 are connected, the user pulls the iron wire 36 upward, and the rubber band 34 is stretched. When the iron wire 36 is pulled to the top of the side rail 21 and released, the iron wire 36 will rebound downward. During the rebound process, the iron wire 36 can be used to cut the tobacco seedlings on the side rail 21. For example, when the tobacco seedling tray is placed on the side rail 21 and the bottom support rod 22, the taller tobacco seedlings will protrude in front of the side rail 21. At this time, the user can quickly slide the iron wire 36 from the front side of the side rail 21 and use the sharp edge of the iron wire 36 to complete the shearing of the protruding part of the tobacco seedlings.

[0029] Furthermore, the left and right ends of the iron wire 36 are provided with connectors 37, which are metal connectors 37, and then a connecting ear 35 is provided at one end of the rubber band 34, which is a metal annular connecting ear 35, and finally the iron wire 36 is buckled and connected with the connecting ear 35 on the rubber band 34 through the connector 37, so that when in use, the iron wire 36 and the rubber band 34 can be quickly installed and connected. In addition, considering the service life of the rubber band 34, the rubber band 34 should be a thickened rubber band 34.

[0030] like Figure 1 As shown, the front sides of the side rails 21 and the bottom support rods 22 are opposite and flush with each other, so that the wire 36 will not be blocked during sliding. At the same time, the top and bottom of the side rails 21 are both arc-shaped structures. Through the design of the arc-shaped structure, the wire 36 will not be hindered by sharp edges when contacting the side rails 21, which helps the wire 36 to slide more smoothly.

[0031] Furthermore, a threaded fixing part 33 is provided between the outer wall of the working wire drum 31 and the connecting rod 3, and the threaded fixing part 33 is threadedly connected to the working wire drum 31 and the connecting rod 3. When in use, the user adjusts the tightness of the rubber band 34 by rotating the working wire drum 31. After adjustment, the threaded fixing part 33 is threadedly connected to the working wire drum 31 and the connecting rod 3, so that the threaded fixing part 33 can limit and fix the rotated working wire drum 31.

[0032] like Figure 1 and Figure 2 As shown, an upper fixed rod 4 is fixedly arranged horizontally at the upper end of the inner wall of the tripod bracket 1, and a rotating sleeve 41 is rotatably arranged on the upper fixed rod 4 along the middle end of the outer wall, and a push rod 42 is fixedly arranged at the lower end of the outer wall of the rotating sleeve 41, and the push rod 42 extends downward, and a pressure rod 43 is fixedly arranged horizontally at the bottom end surface of the push rod 42. When the tripod bracket 1 is unfolded and used, the push rod 42 can be rotated to make the lower end of the push rod 42 and the pressure rod 43 contact the ground, and after contact, the push rod 42 can support the entire tripod bracket 1. At the same time, the setting of the pressure rod 43 can also increase the contact area between the push rod 42 and the ground, which helps to improve its stability and prevent the device from falling down easily. When in use, the user can also step on the pressure rod 43, which can ensure that the entire device can be firmly supported.

[0033] Furthermore, a fixing sleeve 44 is fixedly provided on the left and right sides of the rotating sleeve 41 along the outer wall of the upper fixing rod 4, and the fixing sleeve 44 includes a first fixing sleeve 44 and a second fixing sleeve 44. A limiting rod 45 is fixedly provided along the rear surface between the first fixing sleeve 44 and the second fixing sleeve 44. The limiting rod 45 is used to limit the push rod 42 after turning. When the triangular bracket 1 and the push rod 42 are unfolded, the outer surface of the push rod 42 will contact the limiting rod 45. At this time, the limiting rod 45 can clamp the bottom rod to ensure that the entire device has sufficient stability after unfolding.

[0034] Finally, it should be noted that the above embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed in the present application, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
