Problems solved by technology

Although the fuselage is light and light, the drilling rate is low and the battery life is low, so it is only suitable for household users. At the same time, the existing rechargeable electric hammer has a lot of noise when the hammer is empty, and the casing is prone to damage. Defects such as oil leakage affect the actual experience of the product

Abstract

A novel electric hammer, comprising an electric tool body (3-1), a support (3-2), an oscillating rod bearing transmission structure, a brushless motor (1-7), and a battery assembly. The support is provided inside the electric tool body. The brushless motor and the battery assembly are provided on both sides of the support, respectively. a through hole is formed in the middle of the support for a gear of the brushless motor to pass through. An insertion hole (3-22) is formed below the through hole for the oscillating rod bearing transmission structure to pass through. The oscillating rod bearing transmission structure is meshed with the motor. The electric hammer is simple in structure and can improve the product positioning accuracy and save cost in operation.

Description

technical field [0001] The invention relates to the field of electric tools, more specifically, it relates to an electric hammer. Background technique [0002] The existing rechargeable electric hammer is basically 12V, and it is a Harvard-style structure. The motor is basically a brush motor, the swing rod bearing is 16.5 degrees, the cylinder diameter is basically 17mm, and the battery pack is basically 3 series single-parallel. Although the fuselage is light and light, the drilling rate is low and the battery life is low, so it is only suitable for household users. At the same time, the existing rechargeable electric hammer has a lot of noise when the hammer is empty, and the casing is prone to damage. Defects such as oil leakage affect the actual experience of the product. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and provides an electric hammer with simple and reasonable structure, significantly increased battery li...
