Abstract

The invention provides a multifunctional electric hammer structure applied to the technical field of electric tools. A motor (2) in an electric hammer shell (1) of the electric hammer structure is connected with a control component (3). A motor gear (6) is meshed with a bevel gear (7). The end, extending out of a cylinder body (5), of a ram (8) is connected with one end of a swing rod (9). The other end of the swing rod (9) is connected with an intermediate shaft (4). A bull gear (10) is arranged at the outer portion of the cylinder body (5). A tool drill bit (12) is installed on a cylinder body front end (11). A shifting sleeve (15) is arranged between a ram gear (13) and a drill bit gear (14) and connected with a shifting component (16). The shifting component (16) is connected with a gear shifting operation component (17). The multifunctional electric hammer structure can be conveniently and rapidly switched among a hammering state, a drilling state and a hammering and drilling state, the electric hammer structure does not need to be frequently replaced, and the work efficiency of the electric hammer structure is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electric tools, and more specifically relates to a multifunctional electric hammer structure. Background technique [0002] In the field of existing electric hammer tools, the structure and function of the electric hammer are single. Different electric hammer structures can only realize the functions of hammer and drill respectively, so they cannot meet the market demand. The market demand is more for new products that realize "one machine with multiple functions". At present, there are also some multifunctional electric hammers, but many of these electric hammers have the disadvantages of large size, inconvenient to carry, not wide enough working environment, complicated switching mechanism, and low accuracy of switching mechanism. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple structure, small volume, which can conveniently and qu...
