In the prior art, the Chinese utility model patent with the public document number: CN214981627U discloses a tool connection structure with good installation stability. The utility model can quickly fix the cutter through the provided threaded rod, mounting hole and nut. The first rubber pad and the second rubber pad can effectively buffer the vibration force on the cutter, greatly reducing the probability of the cutter loosening. The first threaded hole, the second threaded hole and the bolt can play a secondary fixing role on the cutter, further improving the installation stability of the cutter.

[0003] However, the utility model aims at the problem that the existing cutting tools are installed by bolts and become loose after being vibrated. However, the cutting tool in the utility model is restricted in the mounting plate, and the mounting plate is mounted to the fixing plate by threaded rods and nuts. The nut structure is not fixed and restricted. When subjected to long-term vibration, the nut is very likely to loosen, so improvement is needed. Utility Model Content

The movable block 12 is movably installed in the storage groove 9. The storage groove 9 is movably connected with a spring 11 at the side position of the movable block 12. The insertion rod 13 is located on the other side of the movable block 12. The two ends of the operating rod 15 pass through the movable groove 10 and are fixedly connected with the movable block 12 in the storage groove 9. The card block 5 is inserted into the installation groove 4, and then several layers of rubber gaskets 6 are placed at the side position of the card block 5, and then the insertion rod 13 of the fixed block 7 is upwardly stored, and the fixed block 7 is then pressed into the installation groove 4. The rubber gasket 6 is compressed by the fixed block 7, so that the rubber gasket 6 is deformed to generate a reverse thrust, and the card block 5 is fixed. As the fixed block 7 is squeezed and moved, the insertion rod 13 moves synchronously. When the insertion rod 13 moves to the position of the socket 14, the insertion rod 13 is inserted downward, thereby fixing the fixed block 7, and the fixing effect is good and it is not easy to loosen.

[0023] like Figure 1 , Figure 4 and Figure 5As shown, a nut 16 and an elastic card plate 17 are fixedly connected to the mounting screw 2, the nut 16 is located at the inner side of the elastic card plate 17, and hanging heads 19 are fixedly connected to the two sides of the elastic card plate 17. The hanging heads 19 are fixedly connected to the mounting seat 1, and a through hole is provided at a position corresponding to the mounting screw 2 on the mounting seat 1, the nut 16 is located between the mounting seat 1 and the elastic card plate 17, and a movable hole 18 is provided on the elastic card plate 17.

After the mounting seat 1 and the mounting screw 2 are movably installed, the nut 16 is loosened upward so that the nut 16 fixes the mounting seat 1, and the elastic card plate 17 is movably installed with the mounting screw 2 through the movable hole 18. The two sides of the elastic card plate 17 are bent upward, so that the hanging head 19 moves upward and is inserted into the hanging hole 21. Then, the elastic card plate 17 restores its deformation under the action of elasticity, so that the hanging head 19 moves downward and is locked with the hanging hole 21, fixedly connecting the nut 16, so that the nut 16 is not easy to loosen or fall off.

[0024] It should be noted that the utility model is a tool installation structure with good fixing effect. The block 5 of the tool 3 is inserted into the installation groove 4. The size and dimensions of the block 5 are adapted to the size and dimensions of the installation groove 4. Then, several layers of rubber gaskets 6 are placed on the side of the block 5 in the installation groove 4. The operating rod 15 is pulled upward to make the movable block 12 move upward, compress the spring 11, and the insertion rod 13 is synchronously moved and stored in the storage groove 9. Then, the fixed block 7 is inserted into the installation groove 4. The fixed block 7 is located at the side of the rubber gasket 6. The fixed block 7 is squeezed hard so that the fixed block 7 squeezes the rubber gasket 6 and the block 5. The rubber gasket 6 is deformed and a reverse thrust is generated through the deformation. The block 5 is fixed and limited. When the fixed block 7 is squeezed hard, the fixed block 7 moves a short distance into the installation groove 4. After the insertion rod 13 moves to the position of the insertion hole 14, the insertion rod 13 is moved downward, and the spring 11 is restored to open, and the movable block 12 and the insertion rod 13 are moved. The reverse push causes the insertion rod 13 to be inserted into the insertion hole 14. Due to the reverse thrust generated by the compression deformation of the rubber gasket 6, the side walls of the insertion rod 13 and the insertion hole 14 are fixed and squeezed against each other, and the spring 11 pushes the movable block 12 and the insertion rod 13 downward, so that the insertion rod 13 is not easy to move upward when human operation is lost, so that the tool 3 and the mounting seat 1 are installed more firmly and not easy to loosen. Then the mounting seat 1 and the mounting screw 2 on the equipment are installed, the nut 16 is installed on the mounting screw 2, and the nut 16 is tightened to fix the mounting seat 1, and then the elastic card plate 17 and the mounting screw 2 are movably installed, the movable hole 18 of the elastic card plate 17 and the mounting screw 2 are movably installed, and the nut 16 is restricted to the inner position of the elastic card plate 17 by the elastic card plate 17, and the hanging heads 19 on both sides of the elastic card plate 17 are installed in the hanging holes 21, so that the elastic card plate 17 is fixedly connected to the mounting seat 1, so that the nut 16 is not easy to loosen and the installation is more stable.
