Description

Pipe cutter with easy control of the force of the switch blade holder

This invention is a pipe cutter that is easy to control the force of the switch blade base. It is mainly used in the pipe cutter technology that can be easily converted into cutting hard pipes or cutting hoses.

According to the facts, the applicant in this case filed an application on August 30, 108, with the application number: 108211588, and the approval was announced on December 21, 108, with the certificate number: M588045 "Roller of the pipe cutter" "Lubrication Structure" new patent case mainly places the pipe to be cut between the knife holder and the two rollers, so that the circumferential surface of the pipe to be cut forms a three-point stable contact state with the cutting wheel cutter and the two rollers. The user only needs to tighten the rotating part of the lead bolt in the clockwise direction to allow the slider to move forward and tighten the compression elastic element and increase the elastic force. On the contrary, when the lead screw is loosened in the counterclockwise direction, When the lead bolt rotates, the slider can be moved back, the elastic element can be loosened, and the elastic force can be reduced. Accordingly, as the pipe wall thickness of the pipe to be cut becomes thinner, the elastic element can be adjusted to prompt the knife holder to automatically feed. The elastic force of the elastic element is used to automatically advance the cutter, so that the cutting wheel cutter can tightly bite the pipe to be cut, so that the knife holder can move forward on the lead bolt to clamp the pipe to be cut and compress it at the same time. The elastic element assists in pre-storing the elasticity of automatic knife feeding. At the same time, hold the main body and the tool holder with your thumb and other fingers respectively, and rotate them in a counterclockwise direction. The cutting wheel can be used to cut the pipe to be cut. At the same time, the cutting wheel can be controlled by the elastic element during the entire cutting process. The elastic force helps the cutting wheel cutter to feed automatically until until the pipe is cut.

However, in the above-mentioned new patent case of "roller lubrication structure of pipe cutter", it is necessary to adjust the elastic force of the elastic element during actual operation, because generally beginners or inexperienced people do not have practical judgment when tightening the lead bolt. According to this, it is difficult to control the optimal force of tool holder feed, which has existing problems and deficiencies that need to be overcome.

The creator is currently engaged in the manufacturing and design of related products, and has accumulated many years of practical experience and experience. In view of the existing problems and deficiencies in the above-mentioned new patent case of "Roller Lubrication Structure of Pipe Cutter", he has actively devoted himself to the spirit of innovation and improvement. The completed pipe cutter is easy to control the force of the switch blade holder.

The technical means used to solve the new problem and the effect compared with the previous technology are: the body is provided with a horizontal part, and the horizontal part is provided with a horizontal receiving groove. The horizontal receiving groove can be used for the sliding sleeve to set the tool holder. There is an accommodating space below the tool holder for the purpose of accommodating a slider. The slider is driven forward and backward by a lead bolt in forward and reverse directions. The slider is in contact with the accommodating space. There is an elastic element between them, the body is provided with a recessed portion or a hollow portion above the horizontal portion corresponding to the horizontal receiving groove, and the tool holder is located above the receiving space corresponding to the front and rear positions of the slider. There are two indicator lines, so that the user can clearly see from the recessed part or the hollow part whether the front and rear of the slider are aligned with the two indicator lines, so as to adjust the most appropriate compression elastic tightness of the elastic element, providing beginners with Or it is the best basis for judgment for inexperienced people to use, and it can improve the effectiveness and achieve its main purpose.

The above-mentioned pipe cutter that is easy to control the force of the spring knife seat, wherein: the slider is in the shape of Inverted L-shaped, the slider is provided with a spring positioning axis corresponding to the elastic element, which is used to set the elastic element.

In the above-mentioned pipe cutter that is easy to control the force of the spring knife seat, the slide block is block-shaped, and the slide block is provided with a spring groove corresponding to the elastic element, which is used as a sleeve for the elastic element.
