The crank handle 51 drives the extension column 52 to rotate in the opposite direction, the extension column 52 drives the threaded column 53 to rotate in the opposite direction, the threaded column 53 drives the slider 54 to move backward, the slider 54 drives the first slide plate 55 to move backward, the first slide plate 55 drives the connecting rod 72 to move backward, and the connecting rod 72, guided by the third through groove 61, drives the second slide plate 57 to move horizontally. The second slide plate 57 drives the pin 59 to move horizontally away from the insert block 22. When the other end of the pin 59 contacts the wall of the mounting groove 41, the pin 59 is completely disengaged from the locking hole 23. Then, the machining table 1 can be moved upward to disassemble the machining table 1 from the support frame 2. The third through groove 61 acts as a guide, converting the forward and backward movement of the first slide plate 55 into the left and right movement of the second slide plate 57. The limiting hole 43 serves as a guide, allowing the pin 59 to move only horizontally left and right. The hanging plate 12 facilitates the hanging of various tools, and the L-shaped bracket 81 and hook 82 on the hanging plate 12 meet the hanging needs of different tools, making it convenient for operators to perform machining. The mounting bracket assembly 14 is used to install LED lights 15, which provide lighting. The limiting grooves 11 on the support rod 10 at different heights allow for height adjustment of the mounting bracket assembly 14, i.e., adjusting the installation height of the LED lights 15, making it convenient for operators of different heights to use this workbench. The shelves 84 and drawers 7 provide storage functions, allowing operators to store various processed items. This utility model allows for quick installation and disassembly of the processing table 1, support frame 2, and support rod 10, facilitating the transportation of the entire workbench and the addition of various equipment.
