The construction content and the functional benefits that can be achieved are listed in a specific embodiment, and are described in detail as follows: An automatic feed pipe cutter, please refer to the first and second figures: Combination diagrams one and two. As shown in the third and fourth figures: a schematic diagram of the three-dimensional decomposition and section combination of the creation. And the fifth figure: is a schematic view of the F-F section of the fourth figure. The main body 10 includes a body 10, a sliding seat 20, a lead bolt 30, a tool holder 40 and two roller rollers 50. The body 10 is L-shaped, and the body 10 is provided with a horizontal portion 11 and a horizontal portion 11 A vertical portion 12 is disposed on the side, and a horizontal receiving groove 13 and a vertical receiving groove 14 are defined in the middle of the horizontal portion 11 and the vertical portion 12. The upper and lower portions of the side walls of the horizontal receiving groove 13 are respectively Two sliding slots 15 are provided, and a sliding seat 20 is provided as a sliding sleeve. The horizontal portion 11 is provided with a through hole 16 corresponding to the wall surface of the vertical portion 12 for wearing a lead bolt 30. The upper and lower sides of the two side wall surfaces of the vertical accommodating recess 14 are respectively provided with two corresponding pivoting holes 17 for pivoting the two pivoting elements Q1 to provide two rollers 50; the size of the sliding seat 20 is just The slider 20 is disposed in the horizontal receiving recess 13 of the body 10, and the slider 20 is provided with two sliders 21 corresponding to the two sliding slots 15 of the body 10, so that the slider 20 can be disposed on the slider by using the two sliders 21 The two chutes 15 are forwarded and retracted. The middle of the sliding block 20 is provided with a screw hole 22 corresponding to the through hole 16 as a screwing guide bolt 30. The upper part of the sliding seat 20 is provided with a joint portion 23, and the joint portion 23 is provided with a pivot hole 24 corresponding to one side of the two rollers 50, and is used as a pivoting member Q2 for pivoting a knife seat 40. The connecting portion 23 is different from the bottom of the other side of the pivoting hole 24, and is provided with a through hole 25 and a screw hole 26 of the coaxial core for locking a countersunk screw 28; The lead bolt 30 is directly locked in the screw hole 22 of the sliding seat 20 through the through hole 16 of the body 10. The lead bolt 30 is externally provided with a rotating portion 31 for facilitating the rotation of the lead bolt 30; The bottom of the blade holder 40 is provided with a coupling groove 41 corresponding to the joint portion 23 of the slider 20 for coupling to the joint portion 23, and the blade holder 40 is provided with a shaft hole corresponding to the pivot hole 24 of the slider 20. 42.

The through hole 46 is a screw hole 47. The shaft of the cutting wheel cutter 45 is provided with a shaft hole 48. The screw P is inserted into the screw hole 47 through the through hole 46 and the shaft hole 48, so that the cutting wheel cutter is provided. 45 is freely rotatable. The knife seat 40 is provided with a top abutting groove 49 corresponding to the screw hole 26 of the sliding seat 20, and is used as a spring 27 for abutting. When the countersunk screw 28 is locked, the spring 28 is tightened. bomb When the countersunk screw 28 is withdrawn, the spring 28 becomes loose and the elastic force becomes small, so that the spring 27 is adjusted to urge the seat 40 as the wall thickness of the pipe member 60 to be cut is thin. The elastic force of the automatic feeding is automatically advanced to the cutting blade by the elastic force of the spring 27, so that the cutting wheel cutter 45 tightly bites the pipe member 60 to be cut; the shaft 50 of the roller 50 is provided with a shaft hole 51 for a pivot The knot member Q1 is pivotally disposed in the pivot hole 17 of the body 10, so that the roller 50 can be freely rotated in the vertical receiving groove 13. One side of the roller 50 is provided with a dodge groove 52, which is used as a dodge to be cut. The enlarged end 61 of the tubular member 60 is used (as shown in Figures 15 and 16).

The original creation by combining the above various component structures provides a self Into the knife and pipe cutter, in practical application: Please refer to the seventh figure: the action diagram of the creation of the pipe to be cut. First, the pipe member 60 to be cut is placed between the blade holder 40 and the two rollers 50, so that the circumferential surface of the pipe member 60 to be cut forms a three-point stable contact state with the cutting wheel cutter 45 and the two rollers 50.

Please refer to the eighth figure: it is a schematic diagram of the action of clamping the pipe to be cut. The lead bolt 30 is locked clockwise, so that the sliding seat 20 can be screwed forward on the lead bolt 30 by the screw hole 22, so that the cutting wheel cutter 45 of the tool holder 40 is centered on the pivoting member Q2. The arc swings to clamp the pipe member 60 to be cut while compressing the spring 27 to assist in pre-storing the elastic force of the automatic feed.

Please refer to the ninth and tenth figures: This is a three-dimensional schematic diagram of the cutting of the pipe to be cut. And the eleventh, twelfth, and thirteenth drawings: the schematic diagrams of the first, second, and third sections of the automatic infeed when cutting the pipe to be cut. And as shown in the fourteenth figure: a schematic view of the section of the pipe to be cut. The user only needs to hold the body 10 and the blade holder 40 with the thumb and the other fingers, and rotates in the counterclockwise direction, that is, the cutting tube 60 can be cut by the cutting wheel cutter 45 while the cutting wheel cutter 45 is in the whole cutting process. By the elastic force of the spring 27, the cutting wheel cutter 45 can be automatically fed until the tube member 60 to be cut is cut.

Based on the above, the author is providing an automatic feed pipe cutter. After the actual production of the creator and the repeated operation test, it is confirmed that the functional benefits expected by the creation can be achieved. The first thing that has never been seen is that it has the value of industrial use.
