[0002] A power distribution cabinet is a key device used in a power system, mainly for receiving, distributing, and controlling electric energy to ensure the safe, stable, and efficient operation of the power system. It usually contains various electrical components such as circuit breakers, contactors, relays, and meters. These components are installed in a metal cabinet body and are interconnected through cables and busbars to achieve the protection, monitoring, and operation of the power system. Power distribution cabinets are widely used in industrial, commercial, and residential buildings and are an indispensable part of the power system.

[0003] During the assembly process of a power distribution cabinet, one of the main factors affecting the assembly efficiency is to fix components such as control switches and protection devices to the cabinet body using screws. Although screw electric tools have been used in the prior art to improve the assembly efficiency, there are still many inconveniences and safety hazards during the assembly process. Specifically, the operator needs to manually hold multiple screws, then manually align them with the assembly positions, and then use an electric tool for tightening. This manual way of holding screws is not only time-consuming and laborious, but also likely to cause the screws to fall to the ground when taking multiple screws, increasing the risk of accidental stepping and injury. At the same time, the process of manually aligning the screw holes is also relatively cumbersome and prone to assembly errors. Summary of the Invention

[0022] The beneficial effects of the present invention are:

[0023] Through the provided fastening mechanism and limiting mechanism, the present invention effectively avoids the problems of difficult screw alignment and cumbersome manual operation. During use, the spiral blade and the key on the output end driven by the motor rotate simultaneously. At this time, the first gear driven by the external meshing transmission of the spiral blade will drive the push-pull rod eccentrically connected to the runner to push the push plate to swing up and down, so as to adjust the telescopic length of the screwdriver. At the same time, the screwdriver rotates synchronously under the cooperation of the key and the key groove cylinder with externally engaged activities, so that the screwdriver realizes the lifting and rotating motion, can accurately align the assembly position and carry out fastening. The limiting mechanism ensures that the screw is stably stored inside before fastening. When the screw enters the limiting cover in the closed state, the second guide cylinder vertically limits the screw. Cooperating with the lifting and rotating screwdriver, the screw can be squeezed out between the two elastically connected limiting covers. Through the linkage of the spiral blade and the gear of the adjustment component, the dynamic telescoping and rotation of the screwdriver are realized. Combining with the elastic clamping function of the limiting cover, the screw can be automatically aligned with the hole position during the fastening process without manual adjustment, significantly improving the accuracy and efficiency of the assembly of the parts of the power distribution cabinet, and eliminating the problems of screw inclination or slippage caused by hand tremors or line-of-sight deviation;

[0024] Through the provided screw storage component and feeding and conveying mechanism, the present invention effectively avoids the problems of easy dropping and low efficiency of manually fetching screws frequently. During use, multiple screws are placed and stored in the box body. During the screw feeding period, the second gear in the feeding and conveying mechanism drives the third rotating shaft connected to the bevel gear to rotate synchronously under the meshing transmission of the first gear, so that the limiting rod moving circumferentially inside the turntable pushes the movable cylinder to perform reciprocating lifting motion. At this time, the bearing plate connected to the other end of the support arm will pick up the screws inside the placing box and then lift them up, and the screws inside the bearing plate will be inverted into the discharging mechanism for arranging multiple screws. Therefore, the automatic grasping and transfer of screws can be realized, and the operator does not need to manually pick up and place the screws, which not only avoids the risk of screw scattering, but also reduces the assembly interruption time, and greatly improves the operation continuity and safety;

[0025] Through the provided discharging mechanism, the present invention effectively avoids the problems of chaotic arrangement or jamming during the screw conveying process. After the transferred screws enter the discharging rack, the inclined guide plate guides the screws to slide along a specific path, and the elastic sheet pops open the overlapping or misaligned screws, only allowing a single row of screws to pass through. Then the screws will slide into the blanking cylinder through the conveying pipe, and the negative pressure fan connected to the hose will improve the sliding efficiency of the screws, ensuring that the screws accurately enter the clamping area of the limiting mechanism. The guiding and elastic sheet screening functions of the discharging rack combined with the negative pressure adsorption and directional conveying realize the single-row and orderly arrangement of screws while the negative pressure stably adsorbs to reduce the screw shaking, ensuring the reliability of the conveying;

[0026] Through the quantitative feeding mechanism provided by the present invention, the problems of excessive screw feeding or blockage are effectively avoided. During use, the support rod drives the sixth rotating shaft to perform periodic swinging under the push of the guiding column. The baffle at the top of the support rod intermittently opens the discharge port of the discharge rack, and only one screw is released into the conveying pipe each time. At the same time, the L-shaped limiting plate rotates with the sixth rotating shaft, pushing the blanking cylinder to deflect in the rotating seat so that its outlet is aligned with the first guiding cylinder, ensuring that the screw only falls when the fastening action is triggered, precisely controlling the quantity of each feeding, avoiding screw accumulation or idling, further reducing the risk of misoperation, and ensuring the accuracy and stability of the assembly process.

At the same time, the key 204 cooperates with the key groove cylinder 205 to drive the screwdriver 208 to rotate, realizing the lifting and rotating motion. In the screw conveying process, the first gear 212 meshes with the second gear 501, driving the third rotating shaft 504 to drive the turntable 506 to rotate. The limiting rod 511 pushes the movable cylinder 510 to lift and lower, so that the support arm 508 drives the bearing plate 512 to grab the screws in the placement box 402 and pour them into the discharging mechanism 6. When the screws pass through the discharging rack 601, the guiding plate 603 guides them to be arranged in a single row, and the elastic piece 604 pops open the overlapping screws and slides into the blanking cylinder 608 through the feeding pipe 605. The negative pressure fan 607 adsorbs and accelerates the conveying through the hose 610.

The blanking cylinder 608 deflects synchronously so that its outlet is aligned with the first guiding cylinder 102. After the screw enters the limiting mechanism 3, the second guiding cylinder 302 guides the vertical positioning, and the return spring 306 elastically clamps the limiting cover 303. When the screwdriver 208 descends, it squeezes the screw to break away from the limiting cover 303, completing the lifting and rotating tightening action. The entire process is powered by the storage battery 105, realizing automatic screw grabbing, precise conveying and efficient tightening.
