Abstract

An improved pipe cutter structure comprises: a main body formed by assembling a sliding base to a bottom base, mounting a knife base on the sliding base, and inserting a screw bolt in the bottom base and the sliding base. The inside of the knife base is provided with a cutting knife body. The bottom base is provided with two rolling wheels. The improved pipe cutter structure is characterized in that: the top of the sliding base is provided with an accommodation slot arranged therein a spring having two ends extended therefrom a first extension section and a second extension section, respectively, and the first extension section will provide an elastic force to assist in automatic knife feeding when cutting a pipe body. Furthermore, the screw bolt is formed by a holding part, an extension section, a fastening ring and a screw thread part. The screw bolt passes through a hollowed section of the bottom base to enable the extension section to be disposed on a fixing part at the same time, and the fastening ring fixedly abuts upon an outer edge of the fixing part thereby allowing the screw bolt to be more stably combined with the bottom base.

Description

Pipe cutter structure improvement

The invention relates to a pipe cutter, in particular to a structure improvement of a pipe cutter, which not only simplifies the manufacturing process, facilitates replacement of parts, reduces production cost, but also achieves both effective and better force.

The pipe cutter of the conventional art has a plurality of holes in the inside of the blade seat and the inside of the slider for setting a plurality of springs and screws, the structure is complicated and the production is cumbersome, and the screw holes will rust after use for a long time, and the thread portion will also have some Wear and tear; In addition, the conventional pipe cutter uses a hollow pivoting element to assemble the parts, and the bonding strength is slightly weak.

Therefore, according to the above-mentioned deficiencies, the prior art still has room for improvement.

Reducing the inside of the tool holder and the slider requires multiple holes to reduce the production process steps, and provides a more stable pivoting element to improve the bonding strength. In addition, the bolt and the base joint portion may not be able to rotate due to the repeated wear of the thread. Tight issues are still to be resolved.

The invention provides an improved structure of a pipe cutter, comprising at least: a body, the system is provided with a sliding seat by a base, and a knife seat is disposed on the sliding seat, and the base and the sliding seat are penetrated through a bolt. The cutter base is internally provided with a cutter body, and the base is provided with two rollers a second receiving hole is formed in the top of the sliding seat, and two corresponding holes are defined in the two side walls of the receiving groove, and the second opening is formed in the tool holder relative to each of the first holes; a spring is disposed in the accommodating groove, and the spring is respectively disposed with a first extending portion and a second extending portion at both ends, and penetrates the spring, each of the first holes and each of the second holes through a fixing spigot Provided in the accommodating slot; at least two spigots, each of the spigots penetrating through the rollers, and disposed at at least two holes corresponding to the base; a fixing portion is disposed at a bottom portion of the base, and the fixing portion is provided with a hollow The bolt is composed of a grip portion, an extension portion, a shackle ring and a threaded portion. The bolt penetrates the hollow portion, so that the extension portion is disposed on the fixing portion, and the shackle ring is abutted. The outer side of the fixing portion is arranged to allow the bolt to be firmly coupled to the base and screwed to the sliding seat.

The top of the accommodating groove has a trapezoidal slope facing downward, so that the horizontal plane of the first extending section is higher than the inclined surface of the accommodating groove.

The radial diameter of the receiving groove is smaller than the radial diameter of the seat.

Wherein, the tool holder and the cutting tool body are disposed with abutting pin and fixed by a C-shaped buckle.

The fixed insertion piece, the resisting insertion piece and each of the insertion ends are solid structures.

Firstly, the present invention omits the plurality of holes provided in the sliding seat and the holder, which simplifies the process of manufacturing the holder and reduces the manufacturing cost. Secondly, the receiving groove is directly disposed on the sliding seat and is accommodated therein. The spring is disposed in the slot, and the feedback force of the automatic feed is provided through the first extension, and if the spring is elastically fatigued due to multiple use, the fixed plug can be directly replaced by the tool. Very convenient; in addition, the fixed plug and each of the plugs The tip is changed to a solid to provide a more stable fixing effect, so that the structural combination is more solid, and the screw used for fixing is replaced by the fixed insert to avoid the problem of wear caused by screw rust and long use of the thread; finally, The base is additionally provided with the fixing portion, and the combination of the extending portion of the bolt and the shackle ring enables the bolt to be fixed on the base, so as to prevent the user from paying attention or rotating over the head during use, so that the bolt and the bolt are The base is separated, causing the body to disintegrate. In addition, the extension is a smooth surface, which can reduce the wear problem of the bolt disposed between the bases and increase the overall durability.

The above described objects, structures, and features of the present invention will be apparent from the following description of the preferred embodiments of the invention.

Referring to FIGS. 1 to 6 , the present invention is an improved structure of a pipe cutter, comprising at least one body 10 , the body 10 is provided with a sliding seat 20 by a base set 12 , and a seat 36 is disposed on the sliding seat 20 . The base 12 and the slide are then passed through a bolt 38. The shank 12 is provided with a cutter body 361. The base 12 is provided with two rollers 18; and a accommodating groove 22 is disposed at the top of the sliding seat 20, and the accommodating groove 22 is Two second holes 241 are defined in the two side walls. The second hole 242 is defined in the second hole 241. The spring 26 is disposed on the receiving groove 22, and the spring 26 is respectively disposed at the two ends. A first extension 261 and a second extension 262 are disposed through the spring 26, the first hole 241 and each of the second holes 242, and are disposed in the accommodating groove 22; The two insertion ends 34 are disposed through the rollers 18 and are disposed on at least two holes 24 corresponding to the base 12; a fixing portion 14 is disposed on a bottom portion of the base 12, and the fixing portion 14 is provided with a hollow portion. The bolt 38 is composed of a grip portion 381, an extension portion 382, a retaining ring 383 and a threaded portion 384. The bolt 38 extends through the hollow portion 16 to set the extension portion 382 to the fixing portion. The portion 14 is caused to abut the outer side of the fixing portion 14 to allow the bolt 38 to be firmly coupled to the base 12. It is screwed to the carriage 20.

The top surface of the accommodating groove 22 has a trapezoidal slope facing downward, so that the horizontal plane of the first extending portion 261 is higher than the inclined surface of the accommodating groove 22.

The radial diameter of the receiving groove 22 is smaller than the radial diameter of the seat 36.
