The knife net shell 33 has a simple disassembly and assembly structure and can be quickly disassembled and assembled. Specifically, when the knife net shell 33 is upwardly sleeved on the outside of the adapter 11, the slider 71 first slides upward in the groove section 1 721, and the slider 71 will also slide into the groove section 2 722 on one side through the circumferential rotation of the knife net shell 33 to form axial fixation. Since the limiting surface 82 is an inclined surface or an arc surface, it is convenient for the slider 71 to pass through the locking convex in the locking direction and thus slide into the groove section 2 722. In the locked state at this time, the slider 71 located in the groove section 2 722 is supported by the plane of the locking convex 8, which can limit the slider from rotating out of the groove section 2 722 to a certain extent to maintain the locked state. When it is unscrewed with force, extrusion deformation will occur, causing the slider 71 to pass through the locking convex 8 in the unlocking direction and slide out of the groove section 2 722. Then the knife net shell 33 can be taken out downward, and the slider 71 slides downward in the groove section 1 721.

Specifically, when the head cover 1c is closed, the hook plate 1c21 contacts the upper end of the hook plate 2 1321 downward. Due to the guidance of the inclined push surface A at the lower end of the hook plate 1c21, it is convenient to gradually push the hook plate 2 1321 outward when the head cover 1c is downward. After the hook plate 1c21 continues to move downward, the first end of the spring member contacts the outer shell 1a, and the second end contacts the outer shell 1a. On the inner side of the pressing portion 131 of the lock hook 13, the spring member can drive the locking portion 132 of the lock hook 13 to swing inward, and make the hook plate 1321 hook on the upper side of the hook plate 1c21, so as to lock the locking end 1c2 on the head cover 1c; when unlocking, pressing the pressing portion 131 inward can drive the lock hook 13 to swing and the locking portion 132 at the other end to move outward, so that the hook plate 1321 is separated from the hook plate 1c21, and the head cover 1c can be opened at this time.

[0043] The head cover 1d is a pluggable cover, which is a pluggable sleeve arranged outside the knife net shell 33. The surface of the protrusion 1d1 is an arc surface, which is convenient for entering and exiting the groove 33, and can realize the connection and fixation of the head cover 1d and the knife net shell 33.
