Embodiment Construction

[0048] 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.

[0049]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. In contrast, when an element is referred to as being "directly on" another element, there are no intervenin...

Abstract

The invention relates to a power tool. The power tool comprises a housing, an output shaft, a storage clamp having accommodation bins, an operation part capable of driving working heads to enter or retreat from the accommodation bin and a detection part movably connected to the housing. An obliquely-pressing part capable of driving the detection part to move is arranged between the detection part and the housing. One end of the detection part is provided with a blocking part and the other end of the detection part is provided with a judgment part located between the output shaft and the storage clamp in an axial direction. The operation part drives the working heads to enter the accommodation bins. When the lengths of the working heads are more than the pre-set length, the judgment part abuts against the working heads such that the detection part is kept at the first position. The blocking part is used for restricting the operation part to move away from the direction of the output shaft. The working heads are prevented from being jammed when the working heads can timely retreat by an operator. When the lengths of the working heads are smaller than or equal to the pre-set length, the judgment part is separated from the working heads such that the detection part moves to the second position under effect of the obliquely-pressing part. The blocking part allows the operation part to move away from the direction of the output shaft.

Description

technical field [0001] The invention relates to a power tool, in particular to a gun drill power tool capable of storing and replacing working heads. Background technique [0002] Existing gun drill power tools generally include electric drills, screwdrivers, impact drills and the like. [0003] Usually, users need to perform different types of operations, such as screwing, drilling, etc., when performing operations. In this way, the working head needs to be replaced frequently, which brings great inconvenience to the operator. On the one hand, the replacement is cumbersome, and on the other hand, the replaced working head is easily lost. [0004] For this reason, there have been some power tools that can realize the storage and quick replacement of working heads. For example, Chinese invention application CN103203707A discloses a power tool, including: a casing; a motor; an output shaft; a transmission mechanism arranged between the motor and the output shaft and capable ...
