Problems solved by technology

However, this type of hand-held power tool usually uses two different output shafts to drive two different work chucks respectively. The technical problem caused by this is that two sets of gears need to be set between the motor of the hand-held power tool and the work chuck. The transmission mechanism drives different work chucks separately, resulting in a complex structure of the transmission mechanism and high requirements for installation accuracy, which increases the cost of the entire hand-held power tool

Abstract

The invention relates to a handheld power tool which comprises a shell, a power system and a working portion. The power system comprises a motor which is accommodated in the shell; the working portion comprises working chucks and an output shaft, and the output shaft is used for transmitting rotation of the motor to the working chucks; the working chucks include a first working chuck and a second working chuck, the first working chuck is arranged at a first tail end of the output shaft, and the second working chuck is arranged at a second tail end of the output shaft. The handheld power tool has the advantages that the two working chucks are driven by the single output shaft, so that a structure between the motor and the output shaft can be simplified, the handheld power tool is simple in installation, and the cost of the handheld power tool can be reduced.

Description

technical field [0001] The invention relates to a hand-held power tool, in particular to a hand-held power tool with double working chucks. Background technique [0002] Handheld power tools typically include hammers, drills, screwdrivers, and impact drills, among others. This type of hand-held power tool usually only has one kind of working chuck, such as an electric hammer only has a hammer chuck, an electric drill and an impact drill only have a drill chuck, and an electric screwdriver only has a screwdriver chuck. This type of hand-held power tool with only one kind of working head needs to manually remove one kind of working head from the chuck when switching from the state of clamping one kind of working head to the state of clamping another kind of working head , and re-clamp another working head. At the same time, because certain types of hand-held power tools have a specific type of work chuck, the types of work heads that can be clamped are limited, resulting in ...
