[0002] Polyethylene (PE) is a thermoplastic produced by the polymerization of ethylene monomers. It is characterized by its simple structure and stable performance, and is one of the most widely produced and used plastics. In industrial production and daily processing, PE materials are widely used due to their good flexibility and corrosion resistance. Because of its good flexibility, corrosion resistance, and ease of processing, PE materials are widely used in packaging, piping, and daily necessities. In practical applications, whether cutting PE sheets to specific dimensions or segmenting PE pipes, cutting tools are often used for this process.

[0003] Traditional cutting tools for polyethylene materials often suffer from an unstable connection between the tool and the grip, leading to loosening or even detachment during cutting. This not only affects cutting accuracy and efficiency but also poses potential safety hazards. Therefore, those skilled in the art have developed a cutting tool for polyethylene materials to address the problems described in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a cutting tool for cutting polyethylene materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutting tool for cutting polyethylene material includes a tool body, a mounting rod, and a grip sleeve. The tool body comprises a tool connecting portion and a tool cutting portion. A mounting rod is fixedly connected to one end of the tool body, and a groove is formed at the end of the mounting rod away from the tool body. A grip sleeve is inserted into the mounting rod, and a groove adapted to the mounting rod is formed at the top of the grip sleeve. A shaped block is fixedly connected to the bottom of the grip sleeve, and the groove adapts to the shaped block. A snap-fit ​​structure is provided inside the grip sleeve, and an opening / closing structure is provided on the outer wall of the grip sleeve.

[0007] As a further embodiment of this utility model: the snap-fit ​​structure includes a guide rod, a positive and negative lead screw, a first bevel gear, a rotating shaft, a second bevel gear, a threaded sleeve, and a snap-fit ​​block. The guide rod is fixedly connected inside the grip sleeve and located on one side of the irregular block, and the positive and negative lead screw is rotatably connected inside the grip sleeve and located on the other side of the irregular block. The first bevel gear is fixedly connected to the positive and negative lead screw.

[0008] As a further embodiment of this utility model: a rotating shaft is rotatably connected to the inner side wall of the grip sleeve, and a second bevel gear is fixedly connected to the rotating shaft. The first bevel gear meshes with the second bevel gear, and a first turntable is fixedly connected through the grip sleeve at the end of the rotating shaft away from the second bevel gear.

[0009] As a further embodiment of this utility model: the positive and negative lead screws are threadedly connected to two threaded sleeves, and the two threaded sleeves are fixedly connected to a snap-fit ​​block at one end close to each other. The irregular block is located between the two snap-fit ​​blocks, and two snap-fit ​​grooves adapted to the snap-fit ​​blocks are opened on the outer wall of the mounting rod.

[0010] As a further embodiment of this utility model: the opening and closing structure includes a movable groove, a round rod, a baffle, a through groove, a limiting plate, a threaded rod, a second turntable, and a positioning block. The outer wall of the grip sleeve is provided with a movable groove, and a round rod is rotatably connected inside the movable groove. A baffle is fixedly connected to the round rod, and a through groove is provided inside the baffle.

[0011] As a further embodiment of this utility model: a limiting plate is fixedly connected to the outer wall of the grip sleeve, and a threaded rod is threadedly connected to the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device achieves a stable connection between the tool body and the holding sleeve through a snap-fit ​​structure. With the help of the matching of the irregular groove and the irregular block, the mounting rod and the holding sleeve are initially positioned and connected, ensuring quick alignment and preventing misalignment during installation. Rotating the first turntable drives the rotating shaft and the second bevel gear to rotate. With the meshing of the first bevel gear and the second bevel gear, the forward and reverse screws are driven to rotate, which in turn drives the two threaded sleeves and the snap-fit ​​blocks to move closer to each other. Finally, the snap-fit ​​blocks are inserted into the snap-fit ​​groove on the outer wall of the mounting rod, thereby firmly snapping the mounting rod into the holding sleeve, realizing a stable connection between the tool body and the holding sleeve. By having the two snap-fit ​​blocks simultaneously clamp the mounting rod, a symmetrical and stable clamping force is formed, which avoids the tool shaking during cutting.

[0015] 2. This device uses an opening and closing structure to cover the placement box. Rotating the second turntable drives the threaded rod to rotate, which moves the positioning block. When the positioning block is inserted into the through slot, it can position and fix the baffle, ensuring that the baffle remains stable in the required position. When the baffle is closed, the movable slot and the placement box form a closed space to prevent cutting debris or liquid from entering and damaging the steel ruler. When it is necessary to remove small tools such as the steel ruler, the threaded rod can be rotated in the opposite direction to drive the positioning block out of the through slot in the baffle, thereby releasing the lock on the baffle. The placement box on the inner side wall of the grip sleeve has an opening that communicates with the movable slot, making it easy for the operator to directly remove the steel ruler from the placement box.

Detailed Implementation

[0024] 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.

[0025] Example 1: Refer to Figure 1-5 This embodiment provides a cutting tool for cutting polyethylene material, including a tool body 1, a mounting rod 3, and a grip sleeve 6. The tool body 1 includes a tool connecting part 101 and a tool cutting part 102. A mounting rod 3 is fixedly connected to one end of the tool body 1, and a groove 4 is formed at the end of the mounting rod 3 away from the tool body 1. The grip sleeve 6 is inserted into the mounting rod 3. A insertion groove 2, adapted to the mounting rod 3, is formed at the top of the grip sleeve 6. A shaped block 7 is fixedly connected to the bottom of the grip sleeve 6, and the groove 4 is adapted to the shaped block 7. A snap-fit ​​structure is provided inside the grip sleeve 6, and an opening and closing structure is provided on the outer wall of the grip sleeve 6.

[0026] The snap-fit ​​structure includes a guide rod 8, a positive and negative lead screw 9, a first bevel gear 10, a rotating shaft 11, a second bevel gear 12, a threaded sleeve 14, and a snap-fit ​​block 15. The guide rod 8 is fixedly connected inside the grip sleeve 6 and located on one side of the irregular block 7. The positive and negative lead screw 9 is rotatably connected inside the grip sleeve 6 and located on the other side of the irregular block 7. The first bevel gear 10 is fixedly connected to the positive and negative lead screw 9.

[0027] A rotating shaft 11 is rotatably connected to the inner wall of the grip sleeve 6, and a second bevel gear 12 is fixedly connected to the rotating shaft 11. The first bevel gear 10 is meshed with the second bevel gear 12. The end of the rotating shaft 11 away from the second bevel gear 12 passes through the grip sleeve 6 and is fixedly connected to the first turntable 13. Two threaded sleeves 14 are threadedly connected to the positive and negative lead screws 9, and a snap-fit ​​block 15 is fixedly connected to the two threaded sleeves 14 at their closest ends. The irregular block 7 is located between the two snap-fit ​​blocks 15, and two snap-fit ​​grooves 5 that are adapted to the snap-fit ​​blocks 15 are opened on the outer wall of the mounting rod 3.

[0028] In this embodiment, the tool body 1 is connected to the grip sleeve 6 via the mounting rod 3 at its end. The end of the mounting rod 3 furthest from the tool body 1 has a shaped groove 4. The top of the grip sleeve 6 has a insertion groove 2 that matches the mounting rod 3. When the mounting rod 3 is inserted into the insertion groove 2, the shaped block 7 at the bottom of the grip sleeve 6 inserts into the shaped groove 4. Since the shaped groove 4 and the shaped block 7 match, the mounting rod 3 and the grip sleeve 6 are initially positioned and connected, ensuring quick alignment and preventing misalignment during installation. Then, the first turntable 13 is rotated, driving the rotating shaft 11 to rotate. The second bevel gear 12 on the rotating shaft 11 rotates accordingly. Since the first bevel gear 10 and the second bevel gear 12 are meshed together... Therefore, the rotation of the second bevel gear 12 will drive the first bevel gear 10 to rotate, which in turn will cause the positive and negative lead screws 9 to start rotating. When the positive and negative lead screws 9 rotate, the two threaded sleeves 14 connected to them will move towards each other or away from each other under the guidance of the guide rod 8. When the two threaded sleeves 14 move towards each other, the locking block 15 fixed on them will move accordingly. Finally, the locking block 15 will be inserted into the locking groove 5 on the outer wall of the mounting rod 3, thereby firmly locking the mounting rod 3 into the holding sleeve 6, realizing a stable connection between the tool body 1 and the holding sleeve 6. By synchronously locking the mounting rod 3 with the two locking blocks 15, a symmetrical and stable clamping force is formed, which avoids the tool shaking during cutting.

[0029] Example 2: Refer to Figure 1-7 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the opening and closing structure includes a movable groove 16, a round rod 17, a baffle 18, a through groove 19, a limiting plate 20, a threaded rod 21, a second turntable 22, and a positioning block 24. The outer wall of the grip sleeve 6 is provided with a movable groove 16, and a round rod 17 is rotatably connected inside the movable groove 16. A baffle 18 is fixedly connected to the round rod 17, and a through groove 19 is provided inside the baffle 18.

[0030] A limiting plate 20 is fixedly connected to the outer wall of the grip sleeve 6, and a threaded rod 21 is threadedly connected to the limiting plate 20. A positioning block 24 is fixedly connected to one end of the threaded rod 21, and the through groove 19 is adapted to the positioning block 24. A second turntable 22 is fixedly connected to the end of the threaded rod 21 away from the positioning block 24 through the limiting plate 20. A placement box 23 is fixedly connected to the inner wall of the grip sleeve 6, and an opening 25 is opened on the placement box 23, and the opening 25 communicates with the movable groove 16.

[0031] In this implementation, commonly used measuring tools such as steel rulers are placed in the storage box 23, avoiding the need for operators to carry extra tools. This is especially suitable for on-site construction or outdoor work scenarios. After the steel ruler is placed, the second turntable 22 can be rotated to drive the threaded rod 21 to rotate. When the threaded rod 21 rotates, the positioning block 24 will move. When the positioning block 24 is inserted into the through groove 19, the baffle 18 can be positioned and fixed to ensure that the baffle 18 remains stable in the required position. When the baffle 18 is closed, the movable groove 16 and the storage box form a closed space to prevent cutting debris or liquid from entering and damaging the steel ruler. When it is necessary to take out small tools such as steel rulers, the threaded rod 21 can be rotated in the opposite direction to drive the positioning block 24 out of the through groove in the baffle 18, thereby releasing the lock on the baffle 18. The storage box 23 on the inner side wall of the grip sleeve 6 has an opening 25 that communicates with the movable groove 16, making it easy for operators to take out the steel ruler directly from the storage box 23.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
