Description

General type electric knife blade holder structure and electric knife

Technical Field

The present disclosure relates to an electric knife, and more particularly, to a universal electric knife holder structure and an electric knife.

Background

The handheld electric knife is a handheld cutter which utilizes electric energy to generate heat to realize cutting, the blade is used as a resistor, the blade is heated through heavy 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 blade shape is changeable, the blades of different shapes 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 foams, sponges, plastics, chemical fiber cloth, non-woven fabrics, filter cloth, plastic ropes and rubber.

Fig. 1 is a tool apron structure of a conventional electric knife, a first tool apron 1-1 and a second tool apron 1-2 are arranged at the front end of an electric knife main body 1, the tails of the first tool apron 1-1 and the second tool apron 1-2 are fixed on the electric knife main body 1 and are respectively connected with corresponding electrodes, the first tool apron 1-1 and the second tool apron 1-2 have the same structure, a threaded hole is formed in the middle of a blade mounting groove of the first tool apron 1-1, and blade connecting spaces are formed in the upper side and the lower side of the threaded hole. When the blade 2 is installed, the first connecting part 2-1 at the tail part of the blade 2 is connected with the first tool apron 1-1, the second connecting part 2-2 is connected with the second tool apron 1-2, and the first connecting part 2-1 and the second connecting part 2-2 of the blade 2 are respectively pressed and fixed on the corresponding first tool apron 1-1 and second tool apron 1-2 through the pressing plate to form fixed and conductive connection of the blade 2. An electric knife can often cooperate the blade use of multiple type and specification, and the structure of different blades is different, but all adopts the clamp plate to compress tightly fixedly. For the first connecting part 2-1 and the second connecting part 2-2 which are both U-shaped structure blades, each connecting part can be inserted into two sides of the cutter holder, the pressing plate is pressed from the middle through the fastening piece, and the blades of the structure are firmly fixed and stably contacted; and to the blade that connecting portion is the I-shaped structure as shown in fig. 1, every connecting portion can only cooperate with one side of blade holder, like this when utilizing the clamp plate to compress tightly blade 2, clamp plate one side is unsettled for can be the tilt state after the clamp plate locking, it is relatively poor to the fixed stability of blade, and lead to blade 2 and the blade holder contact failure who corresponds easily. In order to overcome the problems, most of the existing electric heating knives are provided with the gasket 3, the other side is heightened by the gasket 3 when the connecting part of the blade is pressed by the single side of the pressing plate, so that the pressing plate can not incline or not excessively incline after being locked, and the connection firmness and the contact stability of the blade are ensured.

However, the gasket 3 is a small fitting in the electric knife, and not only is easy to lose in the using process, but also many consumers easily neglect the function of the gasket 3 and choose not to add or not to know the function, because the blade can be clamped and fixed by the pressing plate when the gasket is not available, but the blade is loosened or unstable in contact during the using process, so that the risk is neglected, the blade is easy to loosen or poor in electric contact when the electric knife works, the blade holder generates heat, and the electric knife is easy to be damaged or even generates unnecessary potential safety hazards.
