[0015] 1. In this utility model, the shoulder strap tightening structure, through the combination of a pull-down strap, a buckle plate, a clip frame, and a locking bolt, allows for flexible adjustment of the length of the pull-down shoulder strap according to the user's shoulder width and comfort. Widening the shoulder strap increases the force-bearing area, reduces shoulder pressure, and avoids pain caused by prolonged carrying. The abdominal tightening structure uses Velcro straps to wrap around the abdomen for fixation, and uses a buckle to finely adjust the tightness, so that the strap fits tightly against the abdomen. This not only distributes shoulder pressure but also enhances the overall stability of the strap, preventing the strap from shifting during work. At the same time, its quick-attach design makes it easy to put on and take off, effectively improving the comfort and safety of mowing operations.
[0016] 2. In this utility model, the lawnmower connecting strap passes through the inlet frame, entry port, fabric insertion port, and exit frame of the locking component to form a loop. The rotating threaded column drives the barbed clamping head to embed into the strap through hole. The strap is firmly fixed by the dual action of barbed engagement and surface compression. The limiting plate cooperates with the inlet frame and the exit frame to regulate the strap path and further enhance the fixing effect. The whole assembly ensures that the strap and the lawnmower are firmly connected, avoiding equipment displacement or falling, eliminating safety hazards, and reducing the inconvenience caused by strap slippage, significantly improving the safety and efficiency of lawnmower operation.
