Description

Trigger assembly, control device and nail gun Technical Field The utility model relates to the technical field of nail guns, in particular to a trigger assembly, a control device and a nail gun. Background In current lithium-ion nail gun designs, the core mechanism relies on the operation of a trigger to trigger firing of the nail gun. Specifically, when the user pulls the trigger, the trigger rotates to enable the contact portion of the trigger to contact the button on the micro switch for firing. However, in the actual operation process, after the trigger contact part is contacted with the button of the micro-switch and triggers the nail gun to fire, the vibration generated during the working of the lithium electric nail gun can be directly transmitted to the whole micro-switch because the trigger contact part is not separated from the button yet. This process can cause damage to the internal structure of the microswitch, especially in view of the high frequency vibrations and impact forces generated by the nail gun when it is in operation. In the long term, the service life of the micro switch can be influenced, the maintenance cost and the equipment failure rate can be increased, and the user experience is reduced. Disclosure of utility model In order to overcome at least one of the above-mentioned drawbacks of the prior art, the present utility model provides a trigger assembly, a control device and a nail gun, which can solve the problem of reduced service life of the micro switch caused by the vibration of the gun body transmitted to the micro switch when the trigger and the button are not separated or not separated completely during the firing process of the nail gun. The utility model adopts the technical proposal for solving the problems that: a trigger assembly comprising a trigger and a button, the trigger having a contact portion for contacting the button, the contact portion having a cushioning structure connected thereto for absorbing shock when the trigger and button contact are subjected to shock. Further, the trigger sliding connection has the push rod, the push rod orientation with button one end is contact portion, buffer structure is the elastic component, the elastic component is located the push rod with between the trigger. Further, the trigger is provided with an assembly hole, the push rod and the elastic piece (4) are sequentially inserted into the assembly hole, the contact part is positioned outside the assembly hole, the elastic piece is arranged in the assembly hole, one end of the elastic piece is propped against the bottom wall of the assembly hole, and the other end of the elastic piece is propped against the push rod. Further, the push rod is provided with a chute, the trigger is provided with a fixing pin, and the fixing pin penetrates through the chute to enable the push rod to be limited in the trigger through the chute. Further, a limiting structure is arranged at one end, facing the elastic piece, of the push rod, and the elastic piece is clamped with the limiting structure. Further, the limiting structure is a limiting hole, and one end of the elastic piece, which faces the limiting structure, is arranged in the limiting hole. The utility model also provides a control device, comprising: A micro-switch; A housing; the trigger assembly described above; The trigger is movably assembled on the shell, so that the contact part moves along with the trigger and then contacts with the needle-shaped button.
