A positioning hole 6 is axially arranged in the bobbin 5, and the radial width of the positioning hole 6 is greater than or equal to that of the bobbin positioning shaft 4; when the bobbin 5 is installed, the bobbin 5 is sleeved on the bobbin positioning shaft 4 through the positioning hole 6, and then the bobbin 5 is positioned on the bobbin positioning shaft 4 through the bobbin quick assembly disassembly structure.
An upper opening 7 of the guide compression cover 2 is formed, and the compression block 1 enters the guide compression cover 2 through the opening 7 and is in sliding limit fit with the guide compression cover; the outer side of the pressing block 1 is provided with a guide limiting groove 8 in the vertical direction, the side wall of the guide pressing cover 2 is provided with a guide limiting screw 9 corresponding to the guide limiting groove 8, the guide limiting screw 9 extends into the guide limiting groove 8, the pressing block 1 is assembled in the guide pressing cover 2 in the vertical direction in a sliding mode, and the sliding stroke is determined by the length of the guide limiting groove 8.
The lower end surface of the guide pressing cover 2 is provided with a conical positioning block 10 in a downward protruding mode, and the conical positioning block 10 extends into the positioning hole 6 of the wire barrel 5 to press and position the wire barrel 5. The conical surface of the conical positioning block 10 plays a role in assisting the positioning holes 6 of the bobbin 5 with various specifications to be positioned according to the center of the bobbin positioning shaft 4, the bobbin 5 can be positioned in the axial direction and the radial direction, not only is the positioning fast favorable for fast installation of the bobbin 5, but also the positioning precision of the bobbin 5 can be ensured, and the positioning state is more stable. The maximum radial width of the conical positioning block 10 is greater than or equal to the radial width of the positioning hole 6, and the through hole 3 is formed in the middle of the conical positioning block 10 in the vertical direction for the bobbin positioning shaft 4 to penetrate through.
The pressing block 1 is elastically matched with the guide pressing cover 2 in the vertical direction through a first elastic piece 11, and the first elastic piece 11 acts between the lower end of the pressing block 1 and the bottom plate of the guide pressing cover 2 to help force the guide pressing cover 2 to keep pressing on the bobbin 5.
