[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This quick-change tool device for hardware processing equipment, through the configuration of blades, handles, telescopic rods, springs, and locking pins, allows for rapid blade replacement. First, wear protective gloves and pull the handle to move the telescopic rod towards the central disc. The telescopic rods on both sides move, pressing against the positioning rod, causing the positioning rod to press against the elastic element and move upwards. Pulling the handle outwards disengages the central disc from the locking block. At this point, remove the locking pin from the center of the blade, and the blade can be removed. To install a blade, place the locking pin in the center of the blade, install the locking block on the locking pin, pull the handle to move the telescopic rod closer to the center, and engage the telescopic rod with the groove inside the tool protector. Engage the locking block with the central disc of the telescopic rod, and finally install the locking pin into the housing to complete the blade installation. This eliminates the need for existing methods that use bolts and pressure rings to install tools, instead employing a telescopic rod and spring mechanism for tool replacement and fixation, improving operational convenience and reducing worker workload.

[0012] 2. This hardware processing equipment's quick-change tool device, through the setting of a control ring, lead screw, slider, and connecting block, when the cutting machine needs to move for cutting, rotates the control ring, which drives the lead screw to rotate. The rotation of the lead screw drives the slider threaded on the lead screw to move, the slider drives the connecting block to move horizontally, and the connecting block drives the blade to perform horizontal cutting. This eliminates the existing hand-held cutting method and improves work efficiency by using a combination of lead screw and control ring. Attached Figure Description
