[0025] In order to more clearly illustrate the overall concept of the present invention, the present invention is further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following words indicating orientation or positional relationships, such as "upper", "lower", "left", "right", "longitudinal", "lateral", "inner", "outer", "vertical", "horizontal", "top", and "bottom", are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] A charging tool suitable for an upper furnace, such as Figure 1-Figure 7 As shown, it includes a first connecting rod mechanism and a second connecting rod mechanism, the middle parts of the first connecting rod mechanism and the second connecting rod mechanism are connected by a first hinge 3, one end of the first connecting rod mechanism and the second connecting rod mechanism is connected by a second hinge 4, and the other end of the first connecting rod mechanism and the second connecting rod mechanism is provided with a clamping member 8, and an adjusting cylinder 5 for adjusting the opening size of the clamping member 8 is provided between the first hinge 3 and the second hinge 4.

[0027] In order to facilitate rotation, swinging and movement to adapt to complex movements in planes and spaces, the first link mechanism includes a first link 1 and a third link 6, and the first link 1 and the third link 6 are hinged by a first bolt 9. The second link mechanism includes a second link 2 and a fourth link 7, and the second link 2 and the fourth link 7 are hinged by a second bolt 10. The first hinge 3 hinges the first link 1 and the second link 2, and the second hinge 4 hinges the third link 6 and the fourth link 7.
