[0022] The utility model is described in further detail below.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Combine Figure 1 、 Figure 2 As shown, a new quick-change chuck device is shown, the clamp body 1 includes an upper part 11 and a lower part 12, the left side of the upper part 11 of the clamp body 1 is hinged to the lower part 12, and the right side of the upper part 11 of the clamp body 1 is connected to the lower part 12 through a quick-release component 6.

[0025] The chuck 2 is in the shape of a hollow disc as a whole, and is divided into a first part 21 and a second part 22, the first part 21 and the second part 22 are semicircular and symmetrically arranged, a pin hole is arranged on the left side, the chuck body 1 is connected through the positioning pin 7, and a positioning inclined surface 23 is arranged on the right side.

[0026] In combination Figure 3 As shown in the drawings, the locking wedge 3 is two, and is slidably connected to the right side of the upper part 11 and the lower part 12 of the chuck body 1, the locking wedge 3 is provided with a wedge surface 31 at one end, and the other end is abutted with a compression spring (elastic element 5), the wedge surface 31 of the locking wedge 3 is clamped by the compression spring on the right side and the positioning inclined surface 23 of the chuck 2, so that the chuck 2 is installed.

[0027] The middle part of the locking wedge 3 is provided with a connecting hole 32, the connecting hole 32 is connected with the wedge screw 4, the locking wedge 3 is compressed and moves to the right through the wedge screw 4, so that the chuck 2 is released.
