[0005] In the technical solution, a clockwise external thread structure is provided to guide the rotation of the tap head to form the internal thread of the nut. By changing the original integrated structure into a replaceable tap head, it is convenient for workers to replace the tap head, thereby further reducing the production cost. A counterclockwise external thread butt joint is provided to achieve the docking of the replaceable tap head and the crank structure. Since the rotation is clockwise, the counterclockwise external thread butt joint is affected by the rotational force, which increases the force of engagement with the crank structure.
[0006] As a supplement to the technical solution, a groove bottom end head is arranged at the center of the end of the replaceable tap head, and a circle of arc surface structure is adopted at the edge of the groove bottom end head.
[0007] In the technical solution, the groove bottom end is provided to facilitate contact with the nut, and the arc surface structure is provided to improve the structural strength of the groove bottom end, thereby avoiding the formation of fractures in the groove bottom end.
[0008] As a supplement to the technical solution, three blades are evenly arranged on the outer ring of the groove bottom end, the root of the blade is integrally formed with the groove body structure, and the top of the blade is provided with a clockwise cutting edge.
[0009] In this technical solution, three blades are used to cut the nut, and the clockwise cutting edge is used to process the hole.
[0010] As a supplement to the technical solution, a groove is provided between two adjacent blades, and the groove is added to guide the waste chips, thereby facilitating the discharge of the waste chips.
[0011] Beneficial effects: The utility model relates to a crank tap with a replaceable tap head, which guides the rotation of the tap head by setting a clockwise external thread structure to form an internal thread of a nut, and changes the original integrated structure into a replaceable tap head to facilitate workers to replace the tap head, thereby further reducing production costs. A counterclockwise external thread butt joint is provided to achieve docking of the replaceable tap head and the crank structure. Since the rotation is clockwise, the counterclockwise external thread butt joint is affected by the rotational force, which increases the force of engagement with the crank structure. The utility model has the characteristics of simple structure, reduced production costs, and convenience for workers to quickly replace the tap head. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
[0018] The embodiment of the utility model relates to a crank tap with a replaceable tap head, such as Figure 1As shown in FIG. 4 , the replaceable tap head 1 comprises a replaceable tap head 1 and a crank structure 2. One end of the replaceable tap head 1 has a clockwise external thread structure 4, and the other end of the replaceable tap head 1 is provided with a counterclockwise external thread joint 3. One end of the crank structure 2 is provided with an internal thread hole structure 5 that matches the counterclockwise external thread joint 3, and the other end of the crank structure 2 is provided with a crank 6.
[0019] In the technical solution, a clockwise external thread structure 4 is provided to guide the rotation of the tap head to form the internal thread of the nut. By changing the original integrated structure into a replaceable tap head 1, it is convenient for workers to replace the tap head, thereby further reducing the production cost. A counterclockwise external thread butt joint 3 is provided to achieve the docking of the replaceable tap head 1 and the crank structure 2. Since the rotation is clockwise, the counterclockwise external thread butt joint 3 is affected by the rotational force, which increases the force of engagement with the crank structure 2.
[0020] As a supplement to the present technical solution, a groove bottom end head 9 is provided at the center of the end of the replaceable tap head 1, and a circle of arc surface structure is adopted at the edge of the groove bottom end head 9.
[0021] In the technical solution, the groove bottom end head 9 is provided to facilitate contact with the nut, and the arc surface structure is provided to improve the structural strength of the groove bottom end head 9 to avoid fracture of the groove bottom end head 9.
[0022] As a supplement to the present technical solution, three blades 7 are evenly arranged on the outer circle of the groove bottom end 9, the root of the blade 7 and the groove bottom end 9 are integrally formed, and the top of the blade 7 is provided with a clockwise cutting edge 10.
[0023] In the present technical solution, three blades 7 are used to cut the nut, and the clockwise cutting edge 10 is used to process the hole.
[0024] As a supplement to the present technical solution, a groove body 8 is provided between two adjacent blades 7. The groove body 8 is added to guide the waste chips, thereby facilitating the discharge of the waste chips.
[0025] Example
[0026] When processing, the entire crank tap is installed in the equipment, and the equipment drives the crank tap to rotate. After completion, the nut is processed, and the bottom end head 9 of the groove supports the raw material. Then the clockwise cutting edge 10 of the crank tap rotates to process the inner hole of the nut. After completion, the clockwise external thread structure 4 processes the internal thread of the inner hole. During the processing, waste chips are led out through the groove body 8 and discharged centrally. When replacement is required, the crank tap is first taken out, and then replaced with a new replaceable tap head 1, and then the crank tap is loaded into the equipment again for the next processing.
[0027] The crank tap with a replaceable tap head provided by the present application is introduced in detail above. The principle and implementation mode of the present application are explained in this article by using specific examples. The description of the above embodiments is only used to help understand the method and core idea of the present application.
