The invention relates to a power tool and a working part mounting method. The power tool comprises a shell, a motor, a main shaft and a chuck; the chuck comprises a core body connected with the main shaft, multiple clamping jaws movably arranged on the core body, and an operation sleeve sleeving the outer side of the core body; the operation sleeve is rotated relative to the core body in a first direction to gather the clamping jaws to lock working parts supported on the core body, and is rotated relative to the core body in a second direction to open the clamping jaws to release the working parts supported on the core body; the chuck further comprises a locking module; the locking module comprises a locking piece movably arranged relative to the core body; and the operation sleeve is configured to drive the locking piece to move to lock the core body with the shell in the locking and releasing process of the working parts. In the power tool, operators only shift the operation sleeve to drive the locking piece to move to lock the core body relative to the shell, so that the operation sleeve can be rotated in the first direction or the second direction to gradually gather or separate the multiple clamping jaws to lock or release the working parts.
Description
technical field [0001] The invention relates to the field of hand-held power tools, in particular to a power tool and a method for installing working parts. Background technique [0002] Hand-held power tools such as electric drills have been widely used in people's production and life, and by replacing the working parts, different workpieces can be processed, which has a wide range of application fields and brings great convenience to people's production and life. [0003] However, there is a general-purpose drill chuck with a key at present, and the effect of the key is to tighten or release the chuck to install or remove working parts such as drill bits. However, since the key exists independently of the power tool, it is easy to lose and cause the chuck to be unable to be tightened or released, which brings great inconvenience to the user. Contents of the invention [0004] Based on this, it is necessary to solve the problem that the key of the power tool is easily lo...
