Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an electric hammer. The electric hammer comprises an output head, a rotation device, a hammering device and a drive device used for driving the rotation device and the hammering device. The rotation device is used for driving the output head to rotate. The hammering device is used for driving the output head to conduct axial hammering. The rotation and hammering ratio of the output head is adjusted by adjusting the matching manner of at least one of the rotation device and the hammering device and the drive device. According to the above electric hammer, due to the fact that the matching manner of at least one of the rotation device and the hammering device and the drive device can be adjusted, the work states of the rotation device and the hammering device can be adjusted, and accordingly the output head has different rotation and hammering rations. The drive device drives the output head to rotate, meanwhile, the hammering device drives the output head to axially move, accordingly, the torque and the axial impact force are exerted on a machined workpiece at the same time, the punching efficiency is improved, different work conditions are met, and the punching efficiency of the electric hammer is effectively improved.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric hammer. Background technique [0002] With the development of society, electric hammer, as a kind of electric drill, is mainly used to drill holes in concrete, floors, brick walls and stones, so it is widely used in various fields. On the basis of the electric drill, the electric hammer adds a piston with a crankshaft and connecting rod driven by the motor, and compresses the air reciprocally in a cylinder, so that the air pressure in the cylinder changes periodically, and the changing air pressure drives the hammer in the cylinder to strike back and forth The top of the drill bit, so that hammering can be performed while rotary drilling is performed, increasing drilling efficiency. [0003] At present, the rotation and impact ratio of the electric hammer is a fixed value, which cannot be adjusted according to different media and different hole diameters, so it cannot b...
