Description

Pipe cutter

This creation is about a pipe cutter.

Press, when the general maintenance master or decorator is at the job site, he will carry all the pipe tools with him to carry out the work of cutting the metal pipe fittings. The conventional pipe cutter includes one fixed seat and one knife seat, and is worn by a screw. It is arranged on the tool holder, and by rotating the screw, the knife seat can be controlled to cut the pipe fitting. However, when the conventional pipe cutter performs the cutting pin, when the tool of the tool holder cuts the outer diameter of the pipe member, the user must re-rotate the screw to re-tighten the tool against the pipe member. The cutting can be continued, so that when the pipe is actually cut, it is necessary to repeat this step several times, which makes the process of cutting the pipe parts time-consuming and labor-intensive, and there is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive pipe cutter to solve the above problems.

The main purpose of the present invention is to provide a pipe cutter having an automatic feed function, and the user does not need to rotate the screw all the time during the cutting operation, and the tool holder can automatically feed the knife to continuously cut the pipe.

To achieve the above object, the present invention provides a pipe cutter comprising a body, a tool holder and a drive assembly. The body is provided with an abutting top. The tool holder is slidably disposed on the body, and a tool is disposed on one side of the surface of the surface of the surface. The tool holder includes a receiving groove, and the receiving groove is provided with a first baffle and a second baffle. And the first baffle is adjacent to the abutting top. The driving assembly includes a screw, a stopper and an elastic member. The screw includes an external thread portion. The screw is rotatably disposed on the body and the holder. The external thread portion is screwed with the stopper. The block is located between the first baffle and the second baffle of the accommodating groove, and the block is not rotatable relative to the tool holder, and the elastic member is elastically biased against the block and the first block. Between the baffles so that the seat has a tendency to slide toward the abutting top.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to FIGS. 1 through 6, there is shown a preferred embodiment of the present invention. The pipe cutter of the present invention comprises a body 1, a holder 3 and a drive assembly 4.

The body 1 is provided with an abutting top 2.

The tool holder 3 is slidably disposed on the body 1 and is provided with a cutter 31 on one side of the surface of the abutting top portion 2, the tool holder 3 includes a receiving groove 32, and the receiving groove 32 is provided with a first one. The plate 33 and a second baffle 34 are adjacent to the abutting top 2. In the present embodiment, the abutting top portion 2 includes two rollers 21, and the two rollers 21 are respectively pivotally disposed on the body 1. The cutter 31 is formed in a ring shape and is further disposed on the seat 3 by a pivot 5. The cutter 31 is provided to the seat 3 in a relatively rotatable manner. The pivot 5 ring is provided with a ring groove 51 which is fastened by a buckle 52 to fix the pivot 5 to the knife for conveniently disassembling the cutter 31.

The driving assembly 4 includes a screw 41, a stopper 42 and an elastic member 43. The screw 41 includes an externally threaded portion 411. The screw 41 is rotatably disposed through the body 1 and the holder 3. The threaded portion 411 is screwed to the block 42 , and the block 42 is located between the first baffle 33 and the second baffle 34 of the receiving groove 32 , and the block 42 is not opposite to the seat 3, the elastic member 43 is elastically engaged between the stopper 42 and the first baffle 33, so that the seat 3 has a tendency to slide toward the abutting portion 2. In the embodiment, the block 42 is disposed on the two side walls 38 of the accommodating groove 32. The two side walls 38 are respectively connected between the first baffle 33 and the second baffle 34.

In actual use, when the screw 41 is rotated, the screw 41 will drive the stopper 42 to slide in the direction of the abutting top 2 (as shown in FIG. 4), and the stopper 42 pushes against the elastic member 43 so that The elastic member 43 elastically slides the blade holder 3 toward the top portion 2, and the cutter 31 abuts against a pipe member; when the screw 41 is continuously rotated, the stopper 42 continues to face the top portion 2 In the direction of sliding, the seat 3 and the cutter 31 are unable to move relative to the top 2 due to the abutment of the tubular member, the seat 3 and the stop 42 are relatively slipped and the elastic member 43 is The stopper 42 is pressed against the first baffle 33 to compress (as shown in FIG. 5); at this time, the pipe cutter is rotated relative to the pipe member, and the cutter 31 surrounds and cuts the pipe member, because the elastic member The 43 series normally urges the seat 3 toward the top 2, so that when the cutter 31 is cut into the tube, there is no need to rotate the screw 41 for feeding the cutter 31, the holder 3 will be automatically resisted by the elastic member 43 and move toward the top 2 (as shown in FIG. 6), and the cutter 31 can continue to abut the tube to continue. OK shavings, to achieve the automatic feed of the function.

The extending portion 35 is disposed in the extending portion 35, and the extending portion 35 can lengthen the length of the receiving groove 32 to lengthen the blocking block. 42 The distance to which the seat 3 is relatively slipped.

Specifically, the body 1 includes two opposite side plates 11 and a bottom plate 12 connected to the two side plates 11 , and the seat 3 is slidably disposed between the two side plates 11 . Further, the two side plates 11 of the main body 1 and one of the blade holders 3 are integrally formed with a sliding slot 14 , and the other one is integrally formed with a slider 37 sliding with the sliding slot 14 . In the embodiment, the body 1 is provided with the sliding slot 14 , and the seat 3 is provided with the slider 37 so that the body 1 and the seat 3 can smoothly slide relative to each other. In the embodiment, the tool holder 3 is further provided with a guide rail 36. The guide rail 36 is a closed end toward one end of the abutting top 2. A pin member 13 is disposed through the side plate 11 and extends into the guide rail 36. In order to prevent the seat 3 from coming off the body 1.

The knob 41 is further provided with a knob 44 away from the one end of the holder 3, and the knob 44 is rotated together with the screw 41. The radial dimension of the knob 44 is larger than the radial dimension of the screw 41, and the knob 44 can be conveniently used. The holder holds the screw 41 in a less laborious manner.

The screw 41 is further provided with a limiting member 45. The limiting member 45 and the knob 44 are respectively abutted on both sides of the body 1 to prevent the screw from coming off the body 1.

In summary, the original pipe cutter, since the elastic member normally pushes the seat toward the top, so when the tool is cut into the pipe, there is no need to feed the tool. When the screw is rotated, the seat is automatically rebounded by the elastic member and moves toward the top. The cutter can continue to abut the pipe to continuously cut the pin to achieve the function of automatic feed.
