Preferably, the handle 9 is a quincunx handle, conforming to the ergonomic design.

As a preference, the diameter of the card slot 7 is 6-10mm, which can be installed with various specifications of hexagon socket head bolts and screwdrivers, and the inside of the card slot 7 is provided with a small circular arc groove 7-1, and the circular arc small groove 7-1 Engage with the ball on the hexagon socket bolt, so that the hexagon socket bolt is firmly fixed.

As a preference, the plug 8 can prevent the slot from being damaged when not in use.

As a preference, the spring 4 can withstand the guide post 10 during use, so that the guide post 10 always protrudes from the end of the chuck wrench when no external force is applied to the wrench, so that the wrench cannot stay on the chuck. To achieve the function of preventing safety accidents.

Beneficial effects of the utility model: it can overcome the disadvantages of the prior art, the structural design is reasonable, the tool holder wrench and the chuck wrench are integrated, and the wrench cross bar is designed to have a tool capable of installing a multifunctional hexagonal wrench and a screwdriver , this tool can not only be used as a machine tool wrench, but also can be used for disassembly and maintenance of machine tools. At the same time, the potential safety hazard that the wrench is not taken off from the chuck can be avoided.
