[0022] Please see Figure 1-4 In this utility model, an elastic tool chuck includes a chuck body 1, which is tapered in design. The chuck body 1 has a clamping hole 8 inside and a locking groove 2 on the outer surface. The upper surface of the chuck body 1 has a set of annularly arranged upper elastic slots 3, and the bottom surface of the chuck body 1 has a set of annularly arranged lower elastic slots 4. The chuck body 1 includes a steel substrate 11 and an anti-corrosion and wear-resistant layer 12.

[0023] The steel base material 11 is 65 manganese-titanium quenched steel. The anti-corrosion and wear-resistant layer 12 is formed by electroplating, which can increase the overall mechanical properties of the chuck body 1 and facilitate the effective and stable use of the chuck body 1. A set of anti-slip textures 7 are opened on the inner wall of the clamp hole 8. The anti-slip textures 7 are located in the middle and upper part of the clamp hole 8, which can increase the internal anti-slip effect of the chuck body 1 and facilitate the stable clamping of drill bits or milling cutters.

[0024] The outer surface of the chuck body 1 is provided with annular anti-slip grooves 6. The anti-slip grooves 6 are elliptical grooves, which can enable the installer to hold the chuck body 1 stably and facilitate the installation and operation of the chuck body 1.

The model marks 5 are processed by laser engraving process, which can explain the model of this tool chuck 1 and facilitate the staff's understanding and use.

[0025] The working principle of this utility model is as follows:

[0026] In use, the steel base material 11 made of 65 manganese titanium quenched steel and the electroplated anti-corrosion and wear-resistant layer 12 can increase the overall wear and corrosion resistance of the chuck body 1 and increase the overall hardness of the chuck body 1, making the cutter head of this fixture less prone to deformation. The cooperation of the upper elastic slot 3 and the lower elastic slot 4 increases the high elasticity of the chuck body. When clamping milling cutters, drill bits, etc., the chuck body 1 is first clamped into the mounting nut cap through the locking groove 2, and the drill bit or milling cutter is inserted into the fixture hole 8. Then, the mounting nut cap is threaded into the drill rod of the machine tool, and the tapered chuck body 1 is tightened and compressed by the thread, so as to achieve stable clamping and fixing of the drill bit and milling cutter by the chuck body 1, and then milling is performed.
