Description

Foam electric heating knife

Technical Field

The utility model relates to a foam cutting technical field, more specifically say, it relates to a foam electric heat sword.

Background

The electric knife, as the name suggests, is a hand-held knife tool which utilizes resistance to generate heat to realize cutting, and the blade is just a resistor. At present, two electric heating knives with different principles are mainly arranged on the market, one is that the heating wire is arranged in the blade, and the heating wire heats after being electrified and transfers the heat of the heating wire to the blade; the defects are that the blade is thicker and is slowly preheated, and the blade can only be used for cutting foam products; the other type is that the blade is a resistor, the blade which generates heat is realized through large current, the preheating time of the electric knife is short, the blade can reach a red state only for a few seconds, the efficiency is high, the shape is changeable, the blades with different powers can be selected according to different use occasions, the application range is wide, and the electric knife can be used for cutting low-melting-point products such as foam, sponge, plastic, chemical fiber cloth, non-woven fabric, filter cloth, plastic ropes, rubber and the like.

The chinese utility model patent with publication number CN206042642U discloses an active heat dissipation handheld electric knife, which comprises an electric knife body, wherein a heat dissipation fan is arranged inside or on a casing of the electric knife body, and the heat dissipation fan is positioned near a circuit board inside the electric knife body to dissipate heat of electronic components on the circuit board; the shell of the electric heating knife body is also provided with a vent hole.

In the patent documents, the electric knife can be cooled by arranging the cooling fan and the ventilation holes, so that the service life of the electric knife is prolonged. However, it can be seen from the drawings of the above patent documents that the blade of the electric knife is fixed by the hexagon bolt, and in such a design, the problem of inconvenience in detaching the blade due to the fact that the blade is fixed by the bolt will occur. Therefore, a new solution is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

To fixing the blade and leading to the inconvenient technical problem of blade dismantlement because of with the bolt, the utility model aims to provide a foam electric heat sword to solve above-mentioned problem, it has the installation simply, advantage that work efficiency is high.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a foam electric knife, includes the electric knife body, and the one end of electric knife body is provided with the installation piece that is used for installing the blade, the mounting hole has been seted up to the one end that the electric knife body was kept away from to the installation piece, the mounting groove has been seted up to the one end that the mounting hole was kept away from to the installation piece, mounting groove and mounting hole intercommunication, it presses the briquetting to slide to be provided with in the mounting groove, be connected with elastic element between the bottom of pressing briquetting and mounting groove, press the briquetting and set up the locating hole of fixed blade along the axis direction.

Through adopting above-mentioned technical scheme, when changing the blade on the foam electric heat sword, at first the staff is through pressing the pressure piece, makes the axis of locating hole and mounting hole at same one, takes out the blade that will change, installs new blade in the locating hole the inside again, at this moment, loosens and presses the pressure piece, presses the pressure piece under elastic element's effect, and the orientation is kept away from the direction motion of mounting groove, presses the piece and the blade offsets tightly, makes blade fixed mounting in the locating hole. The design mode is simple and convenient to install, facilitates the replacement of the blade, and effectively improves the working efficiency.
