Embodiment Construction

[0013] Please refer to figure 1 , The electric impact tool 100 of this embodiment includes a body 110 , a first cylinder system 120 , an impact system 130 connected to the first cylinder system 120 , and a second cylinder system 140 .

[0014] The machine body 110 is provided with a driving shaft 112 and an eccentric shaft 114 connected with the driving shaft 112 . The drive shaft 112 and the eccentric shaft 114 are arranged eccentrically in the radial direction.

[0015] The first cylinder system 120 includes a first cylinder 122 , a first piston 124 and a first connecting rod 126 disposed in the first cylinder 122 . One end of the first connecting rod 126 is connected to the first piston 124 , and the other end extends out of the first cylinder 122 and is connected to the eccentric shaft 114 .

[0016] The impact system 130 includes a hammer 132 and an impact rod 134 movably placed in the first cylinder 122 . One end of the impact rod 134 is connected to the hammer 132 , a...

Abstract

The invention relates to an electric impacting tool. The electric impacting tool comprises a first air cylinder system and an impacting system connected with the first air cylinder, and the first air cylinder system comprises a first cylinder body. The electric impacting tool is characterized by further comprising a second air cylinder system, the second air cylinder system comprises a second cylinder body, and a one-way channel from the second cylinder body to the first cylinder body is formed between the second cylinder body and the first cylinder body. According to the electric impacting tool, the first cylinder body is pressurized through the second cylinder body, so that larger impacting energy is provided under the condition that the diameter of the first cylinder body is unchanged.

Description

technical field [0001] The invention relates to electric tools, in particular to an electric impact tool. Background technique [0002] Most of the current electric impact tools use a single cylinder to do work. If the parameters of the impact system are constant, it is basically impossible to increase the impact work. Contents of the invention [0003] Based on this, it is necessary to propose an electric impact tool that can provide greater impact energy than a single-cylinder electric impact tool with the same bore. [0004] An electric impact tool, comprising a first cylinder system and an impact system connected to the first cylinder system, the first cylinder system includes a first cylinder, and is characterized in that it also includes a second cylinder system, the second cylinder The system includes a second cylinder, wherein a unidirectional airflow passage from the second cylinder to the first cylinder is provided between the second cylinder and the first cylin...
