The invention discloses a metal hacksaw frame for fast connection of broken saw blades, which comprises a saw bow body, a movable rear arm saw head adapted to hacksaws of different lengths, a clamping and fixing mechanism, a broken saw connection mechanism and a hole The fixing bolt, the clamping and fixing mechanism is arranged on the top of the front and back of the rear arm saw head, the broken saw connection mechanism is arranged on the bottom of the right side of the rear arm saw head, and the fixed bolt with holes is installed on the rear arm saw head The bottom on the right side of the head; the clamping and fixing mechanism includes an unlocking groove, a convex bolt, an invisible plate, a resistance spring, an unlocking slide and a locking bar; the broken saw connection mechanism includes a receiving groove, a balance weight and a connecting Module, the metal hacksaw frame that the broken saw blade is quickly connected to, the secondary fixing mechanism cooperates with the ancient fixing bolt with holes, which can quickly fix the end of the broken hacksaw blade, so as to achieve the purpose of reusing the broken hacksaw blade to save resources, and at the same time The secondary fixing mechanism increases the contact area with the hacksaw blade, which avoids the problem that the hacksaw blade is easily broken again due to a single point of force.
Description
technical field [0001] The invention relates to the technical field of hardware tools, in particular to a hardware hacksaw frame for quick connection of broken saw blades. Background technique [0002] Hacksaw is a common tool for fitters. It cuts smaller round steel, angle steel, flat steel and workpieces. It mainly includes two parts: saw frame and saw blade. When using, the saw blade is installed on the saw frame. Generally, there are holes at both ends for installation with the hacksaw frame, and the material of the hacksaw blade often causes it to break during use. Under normal circumstances, the most commonly used method when encountering a hacksaw blade breaks It is to replace the rigid strip. [0003] The above-mentioned technical solution not only causes a waste of resources, the broken hacksaw blade cannot be reused, and when there is no replaceable hacksaw blade in the construction process, it needs to wait for repurchasing, which wastes time. The Chinese patent ...
