For example, they are used to connect the wheels to the hubs, secure engine components, and assemble various other parts of the car. Therefore, nuts are undoubtedly one of the indispensable parts in automobile manufacturing and maintenance.

[0003] Chinese patent authorization announcement No. CN219026004U discloses a hole opening device for nut machining, which comprises a workbench, an installation groove is formed on the upper surface of the workbench, an adjusting assembly is fixedly installed inside the installation groove, a fixing assembly is fixedly connected to the upper surface of the adjusting assembly, an installation rod is fixedly connected to the upper surface of the workbench, an installation table is fixedly connected to the upper surface of the installation rod, a punching assembly is fixedly installed on the upper surface of the installation table. By setting the fixing assembly and the punching assembly, the nut is placed between the fixing rings on the fixing assembly, and the nut is fixed by rotating the adjusting bolt using the fixing ring to facilitate hole opening. The fixing assembly is moved to the lower side of the punching assembly, the punching assembly is turned on to start the hole opening operation, so that the nut can be fixed during the hole opening operation of the device, and the safety of the device is increased.

[0004] However, although the above-mentioned hole opening device for nut machining can fix the nut by manually rotating the two adjusting bolts to make the fixing rings approach each other, the synchronicity of the two adjusting bolts cannot be guaranteed by manually rotating the adjusting bolts, which may cause the nut to deviate during clamping, and then the nut may not be concentric with the drill bit after moving to the lower side of the punching assembly, resulting in hole deviation.
