Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a retaining spring slotting tool. Background Art

[0002] The snap ring slotting knife uses a slotting knife driven by a motor to easily open one or more grooves on the inner tube wall to further enhance the expansion strength of the tube. Special slotting knives can also be produced according to user requirements to meet the different requirements of different users.

[0003] However, when the existing retaining spring groove cutter is used, the length of the retaining spring groove cutter is usually fixed. When the operating space is relatively narrow, the staff cannot move the retaining spring groove cutter to the designated position for operation, which has a certain impact on the processing efficiency. At the same time, after the retaining spring groove cutter is used, the blade on the knife handle is exposed to the external environment. Foreign objects falling on the blade will cause the blade to bend and deform, which affects the service life of the blade. In addition, the blade is sharp and can easily injure the staff by mistake, so the safety performance is poor. Therefore, a retaining spring groove cutter is provided. Utility Model Content

The utility model solves the problem that the existing retaining spring groove cutter is inconvenient to adjust the length of the retaining spring groove cutter according to needs during use, and it is inconvenient to protect the blade and has poor safety through the provision of a connecting frame, a threaded rod, a sleeve frame, a protrusion, a spring, a through hole, a connecting groove, a threaded sleeve and a support plate.

[0005] The technical solution adopted by the utility model to solve its technical problems is a spring groove knife, comprising a connecting frame, a sleeve frame and a tool handle, one side of the tool handle is bolted with a cutting blade, one side of the connecting frame is inserted with a handle for driving a threaded rod to rotate, the outer side of the threaded rod is threadedly connected with a threaded sleeve, the outer side of the threaded sleeve is welded with a support plate connected to the tool handle, the inside of the connecting frame is welded with a spring connecting a protrusion, the surface of the sleeve frame is provided with through holes for fixing the protrusion, and the number of the through holes is several, and one side of the connecting frame is provided with a connecting groove for allowing the sleeve frame to slide.

[0006] By adopting the above technical solution, when the length of the retaining ring slot knife needs to be adjusted, the protrusion in the through hole on the surface of the sleeve is pressed, and then the spring in the connecting frame is compressed, and then the protrusion enters the inside of the connecting frame, and then the sleeve is pulled to move on the connecting frame, and the sleeve slides in the connecting groove opened on the surface of the connecting frame. When the adjustment of the sleeve is completed, the spring drives the protrusion to pop out, and then the protrusion enters the through hole opened on the surface of the sleeve, so that the sleeve is fixed, so that the length of the retaining ring slot knife can be adjusted according to the needs;

[0007] When the spring groove cutter is used, turn the handle outside the connecting frame, and then the handle drives the threaded rod to rotate, and then the threaded sleeve outside the threaded rod drives the support plate to move, and then the support plate drives the tool handle to move, and then the blade on one side of the tool handle enters the connecting frame, which is convenient for protecting the blade and improving safety performance.

[0008] Specifically, a sliding block is welded on one side of the protrusion, and a sliding groove for sliding the sliding block is provided on the inner side of the connecting frame.

[0009] By adopting the above technical solution, when the protrusion enters the connecting frame, the sliding block outside the protrusion slides in the sliding groove provided on the inner side of the connecting frame, thereby improving the stability of the movement of the protrusion.

[0010] Specifically, a limiting groove is provided on the inner wall of the connecting frame, and a limiting block connected to the supporting plate is slidably connected to the inner side of the limiting groove.

[0011] By adopting the above technical solution, when the support plate drives the tool handle to move, the limiting block outside the support plate slides in the limiting groove provided on the inner wall of the connecting frame, thereby improving the stability of the movement of the support plate.

[0012] Specifically, a rubber particle sleeve for increasing friction is bonded to the outer side of the handle.

[0013] By adopting the above technical solution, when the handle outside the connecting frame is rotated, the rubber particle sleeve outside the handle increases the friction force on the surface of the handle, making it easier to rotate the handle.

[0014] Specifically, the surface of the spring is sprayed with anti-rust paint to improve corrosion resistance.

[0015] By adopting the above technical solution and spraying anti-rust paint on the surface of the spring, the service life of the spring is increased.

[0016] Beneficial effects of the utility model:
