A protective sleeve is fitted on the surface of the hand handle, and multiple evenly distributed protective pads are fixed on the surface of the protective sleeve. The protective pads are arc-shaped plates made of rubber. The device has two symmetrically arranged limiting plates, and the outer shell surface has grooves corresponding to the insert rod and limiting plates. The insert rod and limiting plates are located in the grooves to limit the movement of the protective plate. A first protrusion is fixedly connected inside the protective plate, and a second protrusion is fixed to one end of the insert rod inside the protective plate, abutting against the first protrusion. A spring is fixedly connected between the facing surfaces of the first and second protrusions. The spring is used to push the second protrusion to move the insert rod. The contact surfaces of the insert rod and the first protrusion are both smooth. The first protrusion cooperates with the second protrusion to prevent the insert rod from dislodging from the protective plate under force. Both the first and second protrusions are arc-shaped plates. A protective pad is used to cooperate with the protective sleeve to increase the friction of the handle, and the protective sleeve is used to prevent the surface of the handle from being damaged by impact. However, the protective plate is difficult to adjust in angle, has low flexibility, and cannot meet more practical needs. Utility Model Content

The second connecting plate has a mounting groove with a hole on its side connecting to the inside of the second connecting plate. A fixing nut is installed inside the mounting groove. Both the mounting groove and the fixing nut are hexagonal. A first internal hexagon screw is installed inside the first mounting hole, passing through the connecting hole and connecting to the fixing nut. The guard plate is then installed with the machine body. The operator aligns the inside of the guard plate with the cutting component and inserts the movable block into the first connecting plate. Between the first and second connecting plates, a fixing nut is inserted into the mounting groove. The movable block is adjusted so that the connecting hole aligns with both the first mounting hole and the mounting groove. A first hexagonal socket screw is then obtained, passing through both the first mounting hole and the connecting hole. The first hexagonal socket screw is threaded into the fixing nut. The operator uses a hex wrench to tighten the first hexagonal socket screw. The first and second connecting plates are subjected to force and pressed against the movable block, thus fixing the movable block. The protective plate is then quickly installed and secured. The operator holds the handle, with their hand in direct contact with the protective pad, and the operation button is pressed to activate the switch. When using a single-hand saw, the guard plate effectively protects against debris. If the angle and distance between the guard plate and the cutting components are insufficient, with the single-hand saw off, loosen the first hex screw with a hex wrench, move the guard plate, and rotate the movable block between the first and second connecting plates to quickly adjust the angle of the guard plate. Then, tighten the first hex screw with a hex wrench to resume use. The guard plate is easy to install and remove, improving protection and safety during use.

A second fixing hole is inside the baffle, a third threaded groove inside the second internal slot, and a fourth hexagon socket screw inside the fourth mounting hole. The fourth hexagon socket screw passes through the second fixing hole and is threaded into the third threaded groove. The third and fourth hexagon socket screws act on the baffle and the interior of the base, respectively, making the baffle difficult to detach and further securing it to improve stability.

[0011] The beneficial effects of this utility model are: The protective plate is installed to the machine body. The operator aligns the inside of the protective plate with the cutting component and inserts the movable block between the first and second connecting plates. The fixing nut is placed into the mounting groove. The movable block is adjusted so that the connecting hole aligns with both the first mounting hole and the mounting groove. The first hexagonal socket screw is then obtained and passes through both the first mounting hole and the connecting hole, connecting with the fixing nut. The operator tightens the first hexagonal socket screw with a hex wrench. The first and second connecting plates are subjected to force and pressed against the movable block, thus fixing the movable block. The protective plate is quickly installed and secured. The operator then holds the screw. The handle area allows direct contact between the hand and the guard. The operation button activates the hand saw, which provides effective protection by blocking debris. If the angle and distance between the guard and the cutting components are insufficient, with the hand saw off, loosen the first hex screw with a hex wrench, move the guard to rotate the movable block between the first and second connecting plates, quickly adjusting the guard's angle. Then, tighten the first hex screw with the hex wrench again to resume use. The guard is easy to install and remove, enhancing safety during use.
