[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a safety protection type sugarcane knife, comprising a knife holder, a handle is fixedly connected to the right end of the knife holder, a blade is rotatably connected to the knife holder through a rotating shaft, the rotating shaft is connected to the knife holder through bolt limiters, a positioning seat is installed on the knife holder, one side of the blade is a cutting surface and the other side is a blunt surface, and a groove is provided on the positioning seat, and the groove fits the shape of the blade.

[0006] Preferably, the tool holder is provided with a plurality of groups of receiving grooves, and an insert rod is slidably provided in the receiving groove, and the insert rod can slide to the position of the groove to prevent the blade from rotating after being flipped.

[0007] Preferably, a spring is installed in the accommodating groove, one end of the spring is fixedly connected to the inner wall of the accommodating groove, the other end of the spring is fixedly connected to the insertion rod, and the end of the insertion rod is fixedly connected to a pull ring.

[0008] Preferably, a rubber sleeve is sleeved on the outer wall of the handle, and the rubber sleeve is evenly distributed with anti-slip patterns.

[0009] Compared with the prior art, the advantages and positive effects of the utility model are:

[0010] 1. In the utility model, during use, the blade is rotatably connected to the knife holder. When the blade is not in use, the staff manually loosens the bolt to rotate the blade until the blade enters the groove position in the positioning seat, and then the insertion rod cooperates with the spring to complete the limiting work of the blade at the groove position. Compared with the conventional sugarcane knife without a protective structure, the utility model avoids scratches caused by bumps and ensures the use of the sugarcane knife in a relatively safe environment. The overall structure is compact and easy for the staff to install and maintain. It is directly installed on the knife holder, optimizing the existing working space, and solving the problem that the blade part of the existing sugarcane knife adopts a fixed structure design, and no protective structure is provided at the position of the blade part. The sugarcane knife is placed on the desktop when not in use, which poses a risk of bumps and scratches.

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] The utility model provides a safety protection type sugarcane knife, comprising a knife holder 1, the right end of the knife holder 1 is fixedly connected to a handle 2, the knife holder 1 is rotatably connected to a blade 301 through a rotating shaft 3, the rotating shaft 3 is limitedly connected to the knife holder 1 through a bolt 302, a positioning seat 4 is installed on the knife holder 1, one side of the blade 301 is a blade surface 303 and the other side is a blunt surface 304, a groove 401 is provided on the positioning seat 4, and the groove 401 and the shape of the blade 301 are mutually matched, The knife holder 1 is provided with a plurality of groups of receiving grooves 101, in which an insertion rod 103 can be slidably provided, and the insertion rod 103 can slide to the position of the groove 401 to prevent the blade 301 from rotating after being flipped, and a spring 102 is installed in the receiving groove 101, one end of the spring 102 is fixedly connected to the inner wall of the receiving groove 101, and the other end of the spring 102 is fixedly connected to the insertion rod 103, and the end of the insertion rod 103 is fixedly connected to a pull ring 104.

[0019] When the safety protective sugarcane knife is actually used, the bolt 302 is screwed into the knife holder 1 when the blade 301 of the sugarcane knife is away from the knife holder 1, so that the sugarcane knife is fixed in the knife holder 1. When it is necessary to turn the blade surface 303 of the blade 301 to the knife holder 1, the staff will unscrew the bolt 302 in advance to facilitate the subsequent rotation of the blade 301 through the rotating shaft 3. At this time, the staff will manually pull the pull ring 104 to drive the insertion rod 103 to move from the position of the accommodating groove 101 to the position away from the knife holder 1, providing space for the blade surface 303 to rotate into the groove 401. When the blade surface 303 is in contact with the groove 401 in the positioning seat 4, the staff will manually loosen the pull ring 104 so that the insertion rod 103 moves to the groove 401 position of the positioning seat 4 under the action of the spring 102, completing the positioning of the blade 301 in the positioning seat 4. The limiting and fixing work of the blade 301 is performed at the position where the blade 301 is placed. At this time, the blunt surface 304 of the blade 301 faces outward, and one side of the blade surface 303 is turned towards the knife holder 1, thereby avoiding scratches caused by bumps. By setting the blade 301 to be rotatably connected to the knife holder 1, when the blade 301 is not in use, the staff manually loosens the bolt 302 to rotate the blade 301 until the blade 301 enters the groove 401 position in the positioning seat 4, and then the insertion rod 103 cooperates with the spring 102 to complete the limiting work of the blade 301 at the groove 401 position. Compared with the conventional sugarcane knife without a protective structure, the utility model avoids scratches caused by bumps and ensures the use of the sugarcane knife in a relatively safe environment. The overall structure is compact and easy for the staff to install and maintain. It is directly installed on the knife holder 1, thereby optimizing the existing working space.

[0020] like Figure 1-3 As shown, a rubber sleeve 5 is sleeved on the outer wall of the handle 2, and the rubber sleeve 5 is uniformly provided with anti-slip patterns 501.

[0021] The effect achieved by the entire embodiment 1 is that, during use, the structure of the rubber sleeve 5 and the anti-slip pattern 501 are used to maintain the user's comfort when holding the device.

[0022] Working principle: When the blade of the sugarcane knife is away from the knife holder, the bolt is screwed into the knife holder to complete the fixed limit of the sugarcane knife in the knife holder. When the blade surface structure needs to be turned into the knife holder, the staff will unscrew the bolt in advance to facilitate the subsequent rotation of the blade through the rotating shaft. At this time, the staff manually pulls the pull ring to drive the insertion rod to move from the accommodating groove position to the position away from the knife holder, providing space for the blade surface to rotate into the groove position. When the blade surface and the groove in the positioning seat are in contact with each other, the staff manually loosens the pull ring so that the insertion rod moves to the groove position of the positioning seat under the action of the spring, completing the limiting and fixing work of the blade at the position of the positioning seat. At this time, the blunt surface structure of the blade faces outward, and one side of the blade surface is turned into the knife holder, avoiding scratches caused by bumps.
