[0035] The installation mechanism is located in the inner cavity of the tool holder 2 and is used for quickly installing the tool rod 5 .

[0036] As a preferred solution of the utility model, the installation mechanism includes: a sleeve 6, a top block 7 and a positioning pin 8;

[0037] The inner cavity of the sleeve 6 is provided with a thread, and the inner cavity of the sleeve 6 is threadedly connected to the surface of the tool holder 2. There are two top blocks 7, and the top blocks 7 are movably arranged in the inner cavity of the positioning groove 4. The top of the top block 7 is provided with an oblique angle. The opposite sides of the two top blocks 7 are fixedly connected to the positioning pins 8, and the opposite sides of the two positioning pins 8 pass through the inner cavity of the tool holder 2. Through the coordinated use of the sleeve 6, the top blocks 7 and the positioning pins 8, the tool rod 5 can be quickly positioned, which is convenient for workers to maintain.

[0038] As a preferred solution of the utility model, a first positioning hole 9 is opened on both sides of the bottom of the tool rod 5, and a second positioning hole 10 is opened in the inner cavity of the tool holder 2 and on the side opposite to the two positioning grooves 4. The tool rod 5 is positioned by a positioning pin 8 on the surface of the first positioning hole 9 opened on the tool rod 5, and the second positioning hole 10 is opened through the tool holder 2 to facilitate the positioning pin 8 to pass through the inner wall of the tool holder 2 and position the tool rod 5.

[0039] As a preferred solution of the utility model, the surface of the sleeve 6 is provided with anti-slip grooves, and the bottom of the inner cavity of the sleeve 6 is provided with rounded corners. The rounded corners are used in conjunction with the beveled corners. By providing the anti-slip grooves on the surface of the sleeve 6, it is convenient to manually twist the sleeve 6, and by providing the rounded corners at the bottom of the sleeve 6, it is convenient to cooperate with the beveled corners and push the top block 7.

[0040] As a preferred solution of the utility model, a limiting groove 11 is provided on the front and rear sides of the positioning groove 4, and a limiting block 12 is fixedly connected to the front and rear sides of the top block 7. The limiting groove 11 is used in conjunction with the limiting block 12. The limiting groove 11 and the limiting block 12 can be used in conjunction with each other to limit the top block 7 to prevent the top block 7 from escaping from the inner cavity of the knife seat 2 when the spring 13 resets the top block 7.

[0043] It should be noted that the specific type of motor to be used is selected by the relevant technical personnel familiar with the field, and the above motors are all existing technologies and will not be elaborated in this solution.

[0044] The working principle of the utility model is as follows: first, when the tool rod 5 needs to be positioned, the tool rod 5 is inserted into the installation groove 3, and at the same time, the sleeve 6 is rotated. When the sleeve 6 moves, it drives the top block 7 to move, and when the top block 7 moves, it drives the positioning pin 8 to move. When the positioning pin 8 moves, it is inserted into the first positioning hole 9, so as to quickly fix the tool rod 5. Secondly, when the tool rod 5 needs to be disassembled, the sleeve 6 is rotated in the opposite direction. When the sleeve 6 moves, it is separated from the abutment state with the top block 7. At this time, the spring 13 applies pressure to reset the top block 7 and the positioning pin 8, so as to facilitate the rapid disassembly of the tool rod 5 and facilitate manual maintenance of the inner cavity of the tool holder 2 and the surface of the tool rod 5.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
