In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., conveyor device 3 is equipped with a motor 31 and a circular rotating disc 34. The motor 31 rotates the circular rotating disc 34, and thread storage holes 35 are evenly arranged on the circumference of the circular rotating disc 34 in line with the threads. The threads enter the thread storage holes 35. The motor 31 is a circular screw that first cuts the groove of the wheel 42, and then passes through the fixed wheel 48, The circular rotating disc 34 that fixes the screw in the screw receiving hole 35 includes: a circular rotating disc 32, with a screw bearing recess in the circumferential direction consistent with the screw; In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of vibration disk 2 conforms to the thread holding hole 35, and the thread can enter the thread holding hole 35 through the discharge port after being arranged in the vibration disk 2. It is preferred to set a guide rail 6 between the outlet of the vibration disk 2 and the screw housing hole 35. The screws enter the screw housing hole 37 from the outlet through the guide rail 6. Through this setting, the screws are automatically arranged and grooved, improving efficiency and saving labor costs

In this embodiment, the linkage pull pipe 33 includes a connecting front pipe 33, a connecting branch pipe 331 that is matched with the connecting front pipe 33, and a positioning pipe 332 that is sleeved on the connecting branch pipe 331. The connecting front pipe 33 is integrally formed with the connecting branch pipe 331, and the inner wall of the connecting front pipe 33 is also provided with an assembly cavity that is matched with the rolling part 37, The tail end of the connecting branch pipe 331 is also connected with an adapter cap 333 and a limited back pipe 334 connected to the outer wall of the adapter cap 333. The connecting front pipe 33 is integrally formed with the connecting branch pipe 333.

The traditional screw drill tail structure 1 includes a rod body 11, a screw head 12 located at one end of the rod body 11, a drill tail 13 located at the other end of the rod body 11, and multiple screw teeth 14 ringed on the rod body 11; Among them, a clamping line 15 is defined around the edge of the drilling tail 13, and the clamping line 15 causes the drilling tail 13 to be symmetrically divided into edge 131 and edge 132. The end of edge 131 and the end of edge 132 respectively form all cutting ends 133. The cutting ends 133 are concave with a quarter turn of chip discharge groove 134 in the same spiral direction, and the chip discharge groove 134 is connected to edge 132, and the chip discharge groove 135 is concave with a quarter turn of chip discharge groove 135 in different spiral curvatures, By connecting the chip removal groove 134 with the chip removal groove 135 through different spiral curvatures, the drilling tail 13 can form a symmetrical and complete chip removal groove up to 190 degrees.

Equipment that requires maintenance at high altitudes or complex working conditions requires a screw loss prevention design. Although traditional captive screws can achieve the goal of preventing detachment, due to the diameter of the screw being smaller than the major diameter of the thread, it is difficult to match the gasket, and the installation of the gasket will be eccentric, which is easy to scratch the surface of the product, affecting the corrosion resistance and appearance of the product.

The main purpose of embedded nuts is to replace directly opening screw holes on injection molded parts, and to enhance the strength of screw holes in injection molded parts. Please refer to Figure 1 to lock the workpiece 3 'onto the injection molded part 2'. The screw 5 'passes through the through hole on the workpiece 3' and is screwed into the screw hole of the embedded nut 1 'to secure the workpiece 3'. The embedding between embedded nut 1 'and injection molded part 2' generally includes two methods: one is to heat the embedded nut 1 'and insert it into the injection molded part 2' by hot pressing; Another method is to integrate the embedded nut 1 'with the injection molded part 2' by injection molding. In order to ensure the bonding strength between the embedded nut 1 'and the injection molded part 2', there are knurls on the outer surface of the embedded nut 4 '.
