Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b): an adjustable circular hole cutter is shown in figures 1 to 6,

an adjustable round hole cutter comprises a connecting column 1 and a connecting block 2 integrally formed on the bottom surface of the connecting column 1, wherein the connecting block 2 is cylindrical, a centering drill 7 is integrally formed on the bottom surface of the connecting block 2 through a support shaft 6, a channel 14 is formed on the connecting block 2, a cross rod 3 is slidably connected in the channel 14, a vertical rod 4 vertically arranged is integrally formed at one end of the cross rod 3, the cross rod 3 and the vertical rod 4 are both rectangular, the bottom end of the vertical rod 4 is connected with a blade 5 in a screw connection mode, a chute 11 arranged along the length direction of the cross rod 3 is formed in the cross rod 3, a plurality of teeth 12 are bonded on both sides of the length direction of the chute 11, an elastic pad 13 positioned between the teeth 12 and the inner bottom surface of the chute 11 is bonded on the inner bottom surface of the chute 11, the elastic pad 13 is made of rubber, a through groove 8 communicated with the channel 14 is formed in the, cog 15 bonds has sliding connection to lead to the interior pressing block 9 of groove 8, lead to the wall of groove 8 both sides and all set up the shifting chute 17 that sets up along its depth direction, sliding connection has slider 16 in shifting chute 17, slider 16 bonds with pressing block 9, one side integrated into one piece that the cog 15 was kept away from to pressing block 9 has a plurality of sand grips 10, a plurality of sand grips 10 are the array distribution, press the size of pressing block 9 and lead to the big or small looks adaptation of groove 8, tooth 12, cog 15, pressing block 9 and sand grip 10 all adopt the plastics material.

When people need to use the cutter, people can install the blade 5 on the vertical rod 4 in a screw connection mode, then people only need to fixedly connect the connecting column 1 with the output end of a drilling gun, when the drilling gun drives the connecting column 1 to rotate, the connecting column 1 drives the connecting block 2 to rotate, the connecting block 2 drives the cross rod 3 and the vertical rod 4 to rotate, the vertical rod 4 drives the blade 5 to rotate and cut, when people need to adjust the cutting aperture size of the cutter, people can press the pressing block 9, when the finger abdomen of people is in contact with the pressing block 9, the friction force generated when the pressing block 9 is in contact with the hand is increased through the convex strips 10, then the pressing block 9 drives the embedded teeth 15 to leave between the teeth 12, and the embedded teeth 15 extrude the elastic cushion 13, so that the elastic cushion 13 is elastically deformed, at the moment, people pull the cross rod 3 in a manual mode to adjust the position of the cross rod 3, the elastic pad 13 and the cog 15 slide relatively, friction force between the elastic pad and the cog 15 is large, people only need to spend larger acting force to pull the cross rod 3, and after people adjust the cross rod 3 to a desired position, people can release hands to enable the elastic pad 13 to release elastic potential energy, the elastic pad 13 pushes the cog 15 to return to between the teeth 12, so that the cog 15 is limited by the teeth 12, the pressing block 9 is limited, the connecting block 2 cannot displace relative to the cross rod 3, further, the cross rod 3 and the connecting block 2 can be well positioned, the sliding block 16 slides in the moving groove 17 in the moving process of the pressing block 9, and good guiding effect on the displacement of the pressing block 9 is achieved, and can prevent to press the piece 9 to drop to because the bolt is easy to take place the condition of smooth silk after long-time use when preventing ordinary cutter from passing through bolt location, reduce the probability that the processing fails in the trompil in-process.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
