[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A cutting tool comprises a cutting body, which is in a rectangular structure and is provided with a U-shaped hole. A moving groove is provided in the cutting body in the width direction, and a pair of moving holes are provided in the cutting body. The moving holes are located on both sides of the U-shaped hole. The spacing between the opening ends of the U-shaped holes is smaller than the width of the inner ends thereof. With this design, when scraping, the opening ends of the U-shaped holes can be clamped on the injection molded parts, thereby facilitating the scraping operation of the injection molded parts and avoiding scratches on the injection molded parts during the scraping process.

[0006] A movable rod is movably provided in the moving hole, a scraper is movably provided in the moving groove, movable outer plates are installed at both ends of the movable rod, an action rod is provided on the outer wall of the movable outer plate, an extended screw is installed at one end of the blade body, and a handle is provided at the outer end of the extended screw, which is convenient for operators to hold when performing scraping operations. A thread sleeve is screwed on the extended screw, and a concave piece is rotatably provided on the thread sleeve. A transverse hole is opened on the horizontal section of the concave piece, and an inclined hole is connected to the outer end of the transverse hole. The outer end of the inclined hole extends inwardly, and the action rod moves in the transverse hole and the inclined hole. The movable concave piece can be moved to facilitate the adjustment of the position of the scraper in the moving groove, thereby facilitating the scraping of flash on edges with lower depths.

[0007] Furthermore, an avoidance groove is provided on the movable outer plate to prevent the blade of the scraper from being hidden in the movable outer plate, thereby affecting the scraping operation.

[0008] Furthermore, a scraping groove is provided on the scraper, and the inner circumference of the scraping groove is a blade-shaped structure. Through the arrangement of the scraping groove, the flash on both sides of an edge can be scraped off simultaneously.

[0009] Furthermore, the scraping groove is in a U-shaped structure, which can be used for processing flash on arc-shaped structures.

[0010] Furthermore, the scraping groove is a concave structure, which can be used to process flash on a square structure with edges.

[0011] Furthermore, a rotating sleeve is provided at the outer end of the thread sleeve to facilitate the operator to rotate the thread sleeve.

[0012] Furthermore, a connecting plate is installed on the concave part, a rack is provided on the connecting plate, a gear is meshed on the rack, the gear is rotatably arranged on the other end of the cutter body, a rotating rod is provided on the gear, the rotating rod passes through the cutter body, rotating concave parts are provided at both ends of the rotating rod, a cutting knife is provided at the outer end of the rotating concave part, the inner side of the cutting knife is a blade, and the outer end of the cutting knife is a tip. The setting of the cutting knife and its tip facilitates the operation of scraping off the flash of the hole structure. The cutting knife can also rotate, so it can avoid scratches on the operator during transfer.

[0013] The advantages of the above technical solution are:

[0014] The utility model facilitates the scraping of flash on the edges of injection molded parts and hole structures, and can avoid scratches on the injection molded parts during the scraping. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

A movable rod 3 is movably provided in the movement hole 12, a scraper 32 is movably provided in the movement groove 11, a scraper groove 33 is provided on the scraper 32, and the inner periphery of the scraper groove 33 is a blade-shaped structure. Movable outer plates 30 are installed at both ends of the movable rod 3, and an avoidance groove 300 is provided on the movable outer plate 30. An action rod 31 is provided on the outer wall of the movable outer plate 30. An extended screw rod 2 is installed at one end of the tool body 1, and a handle 20 is provided at the outer end of the extended screw rod 2, a thread sleeve 21 is screwed on the extended screw rod 2, and a rotating sleeve 22 is provided at the outer end of the thread sleeve 21. A concave piece 23 is rotatably provided on the wire sleeve 21 , a transverse hole 24 is provided on the horizontal section of the concave piece 23 , the outer end of the transverse hole 24 is connected with an inclined hole 25 , the outer end of the inclined hole 25 extends inwardly, and the action rod 31 moves in the transverse hole 24 and the inclined hole 25 .
