1. A safety frame travel adjustment device for a nail gun, comprising
a firing plate (1),
wherein a front end of the firing plate (1) is equipped with a safety frame (4); the safety frame (4) is processed to form a long slot (41); a positioning sleeve (3) is fixed to one side of the firing plate (1), and interacts with the long slot (41) to ensure the safety frame (4) slides along the direction of the firing plate (1);
a side of the firing plate (1) also includes a first spring (2) supporting the safety frame (4);
the side of the firing plate (1) further includes an adjustment seat (6), within which is housed an adjustment component for adjusting the position of the safety frame (4);
the adjustment component comprises a connecting bolt (13), a threaded sleeve (12), an adjustment wheel (15), and an opening and closing rod (9);
the connecting bolt (13) is secured to the safety frame (4) with a locking nut (14); the threaded sleeve (12) is threadedly connected to the connecting bolt (13) and the adjustment wheel (15) is fitted on an outer side of the threaded sleeve (12), capable of driving the threaded sleeve (12) to rotate synchronously;
the adjustment seat (6) includes a first limit part (61) to restrict axial movement of the adjustment wheel (15), with part of the wheel extending outside the adjustment seat (6);
the opening and closing rod (9), coaxially aligned with the connecting bolt (13), has an integral support ring (91) at midpoint of the opening and closing rod (9), flanked by a second spring (8) and a third spring (10);
the second spring (8) is positioned on one side of the support ring (91) opposite to the threaded sleeve (12), acting between the support ring (91) and an inner wall of the adjustment seat (6) via a spacer (7);
the third spring (10) acts between the support ring (91) and an inner wall of the threaded sleeve (12) the adjustment seat (6) further includes a second limit part (62) to restrict the axial maximum displacement of the threaded sleeve (12).
