[0048] To facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0049] Working principle of the present invention:

[0050] Insert the connecting end of the spring collet chuck 32 into the tool hole 11, insert the first fixing bolt 33 from the other end of the tool hole 11, adjust the first tool 2, insert the first tool 2 into the spring collet chuck 32, and install it in place. Then, adjust the first fixing bolt 33. When the first fixing bolt 33 is threadedly connected to the spring collet chuck 32, the spring collet chuck 32 and the first fixing bolt 33 approach each other. During the process of the spring collet chuck 32 penetrating into the tool hole 11, the spring collet chuck 32 is subjected to the pressure of the inner wall of the tool hole 11, so that the spring collet chuck 32 firmly fixes the first tool 2 on the tool body 1, realizing the installation of the spring collet chuck 32 on the tool body 1.

[0051] Adjust the second fixing nut in sequence. The second fixing nut can press the second tool 41 against the side wall of the sliding groove 12 during movement, thereby completing the installation of the second tool 41 on the tool body 1. Adjust the collet chuck nut 31 to realize the fixation of the collet chuck nut 31 on the tool body 1.

[0052] Place the second tool 41 in the sliding groove 12 and adjust the second fixing nut in sequence. The second fixing nut can press the second tool 41 against the side wall of the sliding groove 12 during movement, thereby completing the installation of the second tool 41 on the tool body 1.

[0053] When it is necessary to adjust the position of the second tool 41 in the sliding groove 12, adjust the third fixing bolt 51 in sequence. The third fixing bolt 51 can push the second tool 41 during movement, so that the second tool 41 moves along the length direction of the tool body 1 until the second tool 41 moves to the specified position.

[0054] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
