[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0020] See also Figure 1-4 , a feeding device of a pneumatic milling machine includes a pneumatic milling machine 1, a feeding device 2 is arranged inside the pneumatic milling machine 1, the top of the feeding device 2 is fixedly connected to a mounting plate 3, the top of the mounting plate 3 is provided with a clamp 5, and the side of the clamp 5 is provided with a convenient mounting mechanism 6, the convenient mounting mechanism 6 includes a square groove 61, a mounting seat 63, a power supply 67, and a mounting block 69. The square groove 61 is opened at the top of the mounting plate 3, and the bottom of the square groove 61 is fixedly connected to a compression spring 62. The top of the compression spring 62 is in conflict with the bottom of the clamp 5 in the initial state, and the compression spring 62 is in a taut state in the initial state. The elastic potential energy of the compression spring 62 is greater than the gravitational potential energy of the clamp 5. When the compression spring 62 rebounds, it drives the clamp 5 to bounce upward. A mounting groove 64 is provided on the top of the mounting seat 63, and a card slot 65 is provided on the side of the mounting groove 64. The inside of the card slot 65 is fixedly connected to the power supply 67, and the power supply 67 is fixedly connected to the power supply 67. The magnet 66 and the power supply 67 are arranged on the top of the mounting plate 3. The top of the power supply 67 is electrically connected to the switch button 68. The mounting block 69 is fixedly connected to the side of the clamp 5. A long slot 610 is provided on the side of the mounting block 69. A card block 612 is slidably connected to the inside of the long slot 610 through a telescopic spring 611. The card block 612 is initially in the card slot 65. The telescopic spring 611 is in a stretched state in the initial state. The card block 612 is stuck in the card slot 65 to fix the clamp 5 so that it cannot be separated from the mounting plate 3. When the telescopic spring 611 rebounds, it drives the card block 612 to move into the long slot 610. The depth of the long slot 610 is twice the length of the card block 612. The card block 612 is made of stainless steel. The card block 612 can be completely retracted into the long slot 610. The stainless steel card block 612 will be attracted by magnetism. The speed reduction mechanism 7 is provided inside the square slot 61.

[0021] When in use, when it is necessary to replace the clamp 5 and disassemble the clamp 5, press the switch button 68 above the power supply 67 to turn off the power supply 67. At this time, the electromagnet 66 is powered off and loses its magnetism and no longer attracts the block 612. The telescopic spring 611 rebounds and drives the block 612 to move into the long groove 610. When the block 612 is completely retracted into the long groove 610, the compression spring 62 rebounds and drives the clamp 5 to bounce upward and separate from the mounting plate 3, completing the disassembly. When it is necessary to install the clamp 5 again, align the mounting blocks 69 on both sides of the clamp 5 with the mounting seat 63 The mounting slot 64 on the bracket is lowered, the long slot 610 is aligned with the card slot 65, the bottom of the clamp 5 contacts the compression spring 62, and the compression spring 62 is gradually tightened. The switch button 68 above the power supply 67 is pressed to turn on the power supply 67. At this time, the power supply 67 supplies power to the electromagnet 66 through the wire. The electromagnet 66 generates magnetic attraction to attract the card block 612 into the card slot 65, and the telescopic spring 611 is stretched. The card block 612 is stuck in the card slot 65 to fix the clamp 5 so that it cannot be separated from the mounting plate 3, thereby completing the installation. The installation and disassembly are simple and the structure is stable. Example

[0022] See also Figure 1-5 On the basis of embodiment 1, the deceleration mechanism 7 includes a connecting plate 71 and circular particles 74. The connecting plate 71 is fixedly connected to the bottom of the clamp 5. The side of the connecting plate 71 is hinged with a collision rod 73 through a hinge block 72. The circular particles 74 are fixedly connected to the inner wall of the square groove 61. The collision rod 73 is close to the circular particles 74, and the material of the circular particles 74 is rubber. When the clamp 5 moves up and down, it will drive the connecting plate 71 to move up and down. The up and down movement of the connecting plate 71 will drive the collision rod 73 to contact the circular particles 74. When the collision rod 73 and the rubber circular particles 74 are squeezed, resistance will be generated.

[0023] When in use, based on Example 1, when installing, the clamp 5 moves downward and drives the connecting plate 71 to enter the square groove 61, the connecting plate 71 moves downward and drives the collision rod 73 to move downward and collide with the circular particle 74. At this time, the collision rod 73 is subjected to force below and will deflect upward, and will not be squeezed with the circular particle 74 to produce resistance affecting the installation of the clamp 5. When disassembling, the compression spring 62 rebounds and drives the clamp 5 to bounce upward, and the connecting plate 71 drives the collision rod 73 to move upward. At this time, the collision rod 73 collides with the circular particle 74 and cannot be deflected. It will be squeezed with the circular particle 74 to produce resistance, slowing down the speed and amplitude of the clamp 5 bouncing upward, and preventing it from popping out and falling and causing damage.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
