Quickly switchable trigger assembly

The present invention relates to a trigger assembly that can be quickly switched, provides user operation options, and switches to a click or continuous firing mode.

Because of its advantages of easy carrying, stable power supply and easy operation and use, the small power tools have gradually replaced traditional human tools and become an indispensable tool for construction, civil engineering and decoration. With the maturity of production technology, a variety of more humane power tools continue to ask the market, so that consumers have more diverse choices, and the direction of research and development, from the main purpose of rapid and convenient use, to the multi-functional and Safety and other structures, and the nailing machine is used frequently in the small power tools used in practice.

In order to meet the different needs of the user's work, there is currently a design of a switching mechanism with a single firing and continuous firing mode for the nail trigger mechanism, the purpose of which is to generate a single pressing trigger to generate only a single firing and continuously press the trigger. Different firing modes such as continuous nailing.

As for the conventional switching mode of the trigger switching mechanism of the single and continuous firing, the adjustment switching device is usually set at the adjacent position of the trigger. This conventional design must consider the handling and linkage of the switching mechanism at the same time. As well as many factors such as the location of the group, the overall design result of the whole is difficult to avoid too many components, occupying space, unable to switch quickly, unable to stably achieve the click-to-send function, and often have problems such as click-through failure.

In view of this, the inventor of the present invention has invented a related product development and improvement in order to improve the problems encountered in the prior art, and finally invented a "trigger component that can be quickly switched", thereby reducing components, occupying space, and providing stability. Fire the function.

The main object of the present invention is to provide a "trigger assembly that can be quickly switched", which has the advantages of reducing components, occupying no space, and providing stable firing compared with the prior art.

In order to achieve the above-mentioned purpose and effect, the present invention provides a quick-switching trigger assembly, which comprises: a triggering device, which is provided with a receiving slot, and a through opening is formed at a bottom end of one end of the receiving slot, and the end is provided a groove corresponding to the size of the opening is protruded from the wall of the groove; a knob is pivoted on the opposite end of the receiving groove and provided with a spiral track; a fixed block is arranged in the radial direction of the knob; One end is provided with a driving portion that is slidably disposed on the spiral track; a trigger piece has one end that abuts against the other end of the fixing block and is pivotally coupled by a pivot, and the other end of the trigger piece extends above the opening; and The torsion spring is sleeved on the pivot shaft, and the two ends of the torsion spring respectively abut against the accommodating groove and the trigger piece; thus, the knob is rotated radially, the driving part of the fixed block slides along the spiral track, and the trigger piece is laterally driven. The displacement is above the bump or above the port, and when the trigger is operated, the trigger piece is fixed by the bump card to the click mode, and the trigger piece is swung to the port to the continuous firing mode.
