[0005] A detachable screw structure, comprising

[0006] The rod body has a groove on the outer wall at one axial end.

[0007] A connecting rod, wherein the outer wall of one axial end is provided with a linkage groove for connecting with the rotating shaft of the motor, and the other end is provided with a boss, the boss extends into the groove and is threadedly connected with the inner wall of the groove;

[0008] The flat surface portion is arranged on the circumferential outer wall of one end of the connecting rod extending out of the barrel.

[0009] The rod body is a hollow tubular structure.

[0010] A keyway for cooperating with the rotating shaft of the motor is arranged in the linkage groove.

[0011] A convex ring is provided on the circumferential outer wall of the boss, and the axial end surface of the convex ring contacts the axial outer wall of the rod body.

[0012] A baffle is provided on the circumferential outer wall of the rod body, and the baffle is arranged at one end of the rod body close to the connecting rod.

[0013] The cross section of the baffle is annular.

[0014] The beneficial effects of the utility model are as follows: the utility model provides a detachable screw rod structure, the screw rod and the connecting rod are connected by threads, and the detachable and detachable structure is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a detachable screw structure includes a rod body 1, the outer wall of one axial end is provided with a groove 11, a connecting rod 2, the outer wall of one axial end is provided with a linkage groove 21 for connecting with the rotating shaft of the motor, and the other end is provided with a boss 22, the boss extends into the groove and is threadedly connected with the inner wall of the groove; a flat portion 23 is provided on the circumferential outer wall of the end of the connecting rod extending out of the barrel. When dismantling, clamp the two flat portions with a caliper to clamp the connecting rod, then disassemble the bottom cover of the barrel, and rotate the rod body to dismantle it.

[0019] In this embodiment, as shown in the figure, the rod body is a hollow tubular structure, and the overall weight is relatively light.

[0020] In this embodiment, as shown in the figure, a keyway is provided in the linkage groove for cooperating with the rotating shaft of the motor, which is more convenient to use.

[0021] In this embodiment, as shown in the figure, a convex ring 221 is provided on the circumferential outer wall of the boss, and the axial end surface of the convex ring contacts the axial outer wall of the rod body, so that the installation is more stable.

[0022] In this embodiment, as shown in the figure, a baffle 24 is provided on the circumferential outer wall of the rod body, and the baffle is provided at one end of the rod body close to the connecting rod to block the material and reduce the possibility of the material entering the connecting rod. The outer wall of the baffle and the inner wall of the barrel can be clearance-matched.

[0023] In this embodiment, as shown in the figure, the cross section of the baffle is a circular ring.

[0024] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
