[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Reference Figure 1-3As shown, the aluminum alloy ball knife includes a handle 1, a cutting head 2 arranged at one end of the handle 1, a mounting ring 3 is provided on the outer surface of the handle 1 near the cutting head 2, and a locking assembly 4 is provided on the outer surface of the mounting ring 3 to drive the mounting ring 3 and the handle 1 to form a lock. The locking assembly 4 includes an annular slide 401, a knob 402, and a screw 403. The annular slide 401 is provided on the outer surface of the mounting ring 3, the knob 402 is rotatably provided on the annular slide 401, and the screw 403 is provided inside the annular slide 401. One end of the screw 403 passes through the mounting ring 3 and is threadedly connected to the handle 1. The other end passes through the annular slide rail 401 and the knob 402, and is connected to the knob 402 in a transmission manner. The knob 402 is provided with an annular slide groove that matches the annular slide rail 401. The knob 402 rotates stably on the annular slide rail 401 through the annular slide groove. The knob 402 is threadedly connected to the screw 403. By rotating the knob 402, the screw 403 is driven to reciprocate along its axial direction. A connecting hole that matches the screw 403 is provided in an annular shape on the tool handle 1. By rotating the knob 402, the screw 403 is locked or separated from the connecting hole, and the mounting ring 3 is fixed to the outer surface of the tool handle 1.

[0019] A jet assembly is provided on the side of the mounting ring 3 close to the cutter head 2, and the jet assembly includes an air intake shell 701 and a nozzle 702. The air intake shell 701 is mounted on the tool handle 1 and is connected to the side of the mounting ring 3 close to the cutter head 2. The outer diameter of the air intake shell 701 is larger than the outer diameter of the mounting ring 3, and the air intake shell 701 is a circular ring structure. The nozzle 702 is annularly arranged on the side of the air intake shell 701 close to the cutter head 2, and the air outlet of the nozzle 702 faces the cutter head 2. An annular cavity matching the nozzle 702 is provided inside the air intake shell 701. High-speed air enters the annular cavity of the air intake shell 701, and is then sprayed from the nozzle 702 to the outer surface of the cutter head 2 to clean waste chips and debris adhering to the outer surface of the cutter head 2.

[0020] An annular groove 101 is provided on the shank 1 on the side of the mounting ring 3 away from the jet assembly. An elastic clip 5 with a C-shaped structure is clamped inside the annular groove 101. The open end of the elastic clip 5 is smaller than the size of the annular groove 101. The open end of the elastic clip 5 is symmetrically provided with flared portions 501. The distance between the two flared portions 501 gradually increases from the inside of the elastic clip 5 to the outside. The two sides of the elastic clip 5 conflict with the inner walls of the mounting groove 101 on both sides. When the elastic clip 5 is connected to the mounting groove 101, the flared portion 501 first aligns with the mounting groove 101. The inner wall of the elastic clip 5 conflicts with the inner wall and is squeezed by the inner wall, causing the flared portion 501 to flare in the opposite direction, causing the elastic clip 5 to undergo elastic deformation until the inner wall of the elastic clip 5 conflicts with the mounting groove 101. The squeezing force on the flared portion 501 disappears and it rebounds to reset, causing the knife handle 1 at the mounting groove 101 to enter the elastic clip 5, and then the elastic clip 5 is clamped and fixed, and the two sides of the elastic clip 5 conflict with the inner walls on both sides of the mounting groove 101 to limit the axial movement of the elastic clip 5, making the fixation of the elastic clip 5 more firm and stable.

[0021] A fan 6 is provided on the outer surface of the elastic clamp 5, and the fan 6 is connected to the jet assembly through a pipeline. The rear end face of the fan 6 is fixedly connected to the elastic clamp 5, and the fan 6 is fixed to the knife handle 1 through the elastic clamp 5. The fan 6 includes an outer shell 601, an air intake assembly 602, and a connecting arm 603. An air inlet 604 is opened at the center of the front end face of the outer shell 601, and the air intake assembly 602 is fixed on the inner wall of the air inlet 604 through the connecting arm 603. The fan 6 is connected to the air intake shell 701 through a pipeline. The air intake assembly 602 is composed of an air intake fan, a motor, a battery, etc., which guides the external air from the air inlet, sends it to the inside of the air intake shell 701 at high speed through the pipeline, and blows it to the outer surface of the cutter head 2 at high speed from the nozzle 702 to clean the waste chips adhered to the outer surface of the cutter head 2.

[0022] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
