Yueluo is about a special fastener and its screwdriver. That is, the Y screw and its screwdriver. In order to prevent the leakage of new product manufacturing technology and prohibit others from arbitrarily opening the shell of the new product or disassembling the relevant parts, it is necessary to take effective precautions against their own products, and the use of special fasteners is one of the purposes of Yueluo. This kind of screw can also be widely used in the fixation of some public equipment, for the fastening and fixing of parts that are afraid of disassembly and theft, so as to play a certain protective role.
nut is a nut, a part that is screwed together with a bolt or screw for fastening.

Further, it also includes a motor, the motor is provided with a thruster that makes the cutting wheel move towards the conveying device, the other end of the motor is provided with a bearing, the output end of the motor is provided with a special-shaped wheel, the special-shaped wheel is toothed with the bearing, and the motor drives the special-shaped wheel to rotate. , move the cut-off wheel closer to or away from the conveyor.
It can be seen from the figure that no matter how the screw core swings, it will not fall off from the screw sleeve. This is because part of the bead 5 is stuck in the hole 6 of the screw sleeve 1 and the other part is stuck in the screw core 2. In the groove 8, it plays the role of positioning. If the screw sleeve rotates clockwise, the beads 5 can only slide in the groove 8 of the screw core 2 under the driving of the screw sleeve 1 and cannot drive the screw core 2 to rotate. If the screw sleeve 8 rotates in the opposite direction, the bead 5 will be stuck on the stop 7 of the screw core 2 so as to drive the screw core 2 to rotate.
