Problems solved by technology

However, due to the complex manufacturing process of many existing marking machines, lasers or air compressors are required as driving sources, resulting in bulky size and high price, so it is difficult to popularize them in a large area among ordinary users.

Embodiment Construction

[0022] figure 1 Shown is an electric impact tool mainly used for engraving work, which includes a pen-shaped housing 1 with an open end and a closed end 12, the closed end 12 of the housing 1 is connected to the housing The body part 11 is screwed. The housing 1 is designed in the shape of a pen, which is not only attractive, but also convenient for handheld use. A power device for driving the tool to move linearly is installed in the housing 1, which is the core part of the impact tool. The open end of the housing 1 is installed with a tool holder device 6 for clamping a tool 7 .

[0023] The power device includes an electromagnetic coil 2 fixed inside the housing, the electromagnetic coil is connected to the pulse power supply device; the impact rod 3 can be moved axially along the guide part 13 located in the housing, and the impact rod 3 can move axially Pass through and both ends protrude from the inner cavity of the electromagnetic coil 2; the first elastic element 4 ...

Abstract

The invention discloses an electric impact tool, the main technical point of which is that an electromagnetic coil connected with a pulse power supply device is arranged inside the shell; The impact rod is provided with an iron core part made of magnetically permeable material, and the iron core part is located at a position where the impact rod can move toward the opening end of the housing when subjected to a magnetic force; in a free state, the first elastic The element and the second spring element delimit the striking rod in a defined initial position. In the present invention, the linear motion of the impact rod can be directly generated by magnetic force without conversion from rotational motion, so it works quietly, has reliable transmission, is convenient to use, and the volume of the whole machine is also greatly reduced. The stroke and impact frequency can be easily controlled, and it is widely used in different fields of operation such as tattooing, engraving, woodworking chisel, magnetic engraving, hammering or marking.

Description

technical field [0001] The invention relates to the technical field of electric impact tools, in particular to an electric impact tool used for operations such as tattooing, engraving, woodworking chisel, magnetic engraving, hammering or marking. Background technique [0002] Known tattooing tools, such as eyebrow tattooing machine or tattoo machine, its principle is to penetrate the epidermis of human skin through tattooing needles, and deposit the pigments on the tattooing needles into the epidermis to form various patterns. In the process, the tattooing needle makes a linear reciprocating motion, and sometimes it is necessary to adjust the frequency and strength of the tattooing needle. The power in the known structure is provided by the motor, and its rotary motion can be converted into a linear motion through a series of transmission devices. In this way, the eyebrow tattoo machine or tattoo machine is not only noisy, but also has low transmission efficiency and relativ...
