The mounting seat 31 is mounted on an axial end of the rotating wheel 1. Preferably, the mounting seat 31 is fixed to an axial end of the rotating wheel 1 by bolts. The mounting seat 31 is roughly a hollow cylinder with one end open. A through hole 311 is provided at the closed end of the mounting seat 31. The pressing member 32 is movably mounted in the mounting seat 31. The pressing member 32 includes a coupling portion 320 coupled to the mounting seat 31, and a pressing portion 321 at least partially protruding from the open end of the mounting seat 31. Preferably, the pressing member 32 is roughly a hollow cylinder with one end open, and the open end of the pressing member 32 is arranged toward the mounting seat 31. Preferably, the diameter of the coupling portion 320 is larger than the diameter of the pressing portion 321. One end of the engagement portion 320, adjacent to the pressing portion 321, can be stopped against an inner annular protrusion on the open end of the mounting seat 31, which extends radially inward from the mounting seat 31. The outer circumference of the engagement portion 320 is provided with multiple grooves 322.

The first locking member 36 is movably engaged in the first mounting hole of the mounting groove 11, and the second locking member 38 is movably engaged in the second mounting hole of the mounting groove 11. When the pressing member 32 moves relative to the mounting seat 31, the pressing member 32 pushes the follower 34 to move, the follower 34 drives the first locking member 36 to move, and the connecting column 37 drives the second locking member 38 to move, so that the first locking member 36 and the second locking member 38 are close to or away from each other.

[0037] The first locking member 36 is generally cylindrical in shape. It partially extends from the through-hole 311 of the mounting base 31. An engagement hole 61 is defined in the middle of the first locking member 36, into which the follower body 341 of the follower 34 engages. An elastic member 35 is disposed between the first locking member 36 and the pressing member 32. Preferably, the elastic member 35 is a spring.

[0038] When the pressing member 32 is pressed, the pressing member 32 moves downward relative to the mounting seat 21, and the first pushing portion 323 drives the follower 34 to move along the first direction under the action of the first inclined surface and the first engaging surface 42. The follower 34 drives the first locking member 36 toward one end of the second locking member 38 to move into the first mounting hole under the action of the follower body 341 and the engaging hole 61. At the same time, the connecting column 37 drives the second locking member 38 toward one end of the first locking member 36 to move into the second mounting hole. The required lead core receiving plate 2 is placed in the corresponding mounting groove 11. After that, the pressing member 32 is released. Under the action of the elastic member 35, the pressing member 32 moves upward relative to the mounting seat 31. The second pushing portion 324 drives the follower 34 to move along the second direction under the action of the second inclined surface and the first engaging surface 43. Under the action of the follower body 341 and the engaging hole 61, the follower 34 drives the first locking member 36 to move into the mounting groove 11 and partially engage in the first connecting hole of the lead core receiving plate 2. At the same time, the connecting column 37 drives the second locking member 38 to move into the mounting groove 11 and partially engage in the second connecting hole of the lead core receiving plate 2.
