A fastening mechanism 8 for rotating and fastening components is provided inside the base plate 7. The fastening mechanism 8 includes a movable groove 812 on opposite sides of the base plate 7, and a movable disc 811 movably mounted inside the movable groove 812. The outer side of the 11 is closely attached to the inner side of the movable groove 812. The top surface of the movable groove 812 has a groove 82. A limiting block 83 is movably installed inside the groove 82. A limiting screw 81 is movably installed on the top surface of the limiting block 83. A fixed cylinder 89 is fixedly installed on the opposite side of the movable disc 811. An adjusting screw 86 is movably installed on the side of the movable disc 811 away from the fixed cylinder 89. Several limiting grooves 84 are opened on the outer side of the movable disc 811, and the several limiting grooves 84 are evenly distributed circumferentially on the outer side of the movable disc 811. The several limiting grooves 84 are all adapted to the size and specifications of the limiting block 83. A drive is fixedly installed on the side of the inner cavity of the fixed cylinder 89 near the adjusting screw 86. A motor 87 is mounted on a fixed cylinder 89, with a mounting cylinder 85 movably installed on the side away from the adjusting screw 86. A gear 88 is movably mounted inside the mounting cylinder 85. Several toothed blocks 810 are fixedly mounted on the inner side of the mounting cylinder 85, and these blocks are evenly distributed circumferentially. A clamping mechanism 9 for holding parts is provided on the opposite side of the mounting cylinder 85. The bottom surface of the slider 4 is slidably mounted inside the slide groove 2. The right end of the positive and negative threaded screw 3 passes through one side of the slider 4 and is movably mounted on the right side of the slide groove 2. The left end of the positive and negative threaded screw 3 movably passes through the interior of the slide groove 2 and is fixedly mounted at the output end of the DC motor 6. The top end of the limiting screw 81 is threaded... The top surface of the groove 82 is penetrated and extends to the outside of the base plate 7. The rotating limiting screw 81 can drive the limiting block 83 to be inserted into the limiting groove 84. The end of the adjusting screw 86 away from the fixed cylinder 89 is threaded through the interior of the movable groove 812 and extends to the outside of the base plate 7. The rotating adjusting screw 86 can drive the clamping mechanism 9 to rotate and tighten the parts through the movable plate 811. The output end of the drive motor 87 is movable through the interior of the fixed cylinder 89 and fixedly installed on one side of the gear 88.

[0023] The adjustable screw 86 and movable disc 811 can drive the parts to rotate for fastening. In use, the parts are clamped by the clamping mechanism 9, and then the adjustable screw 86 is rotated to drive the movable disc 811 to rotate and push it in the direction of the clamping mechanism 9. At this time, the clamping mechanism 9 makes the parts rotate for fastening. It is convenient to use and can be directly assembled.

[0024] Figures 2-3 The second embodiment is shown. The main difference from the first embodiment is that the clamping mechanism 9 includes a fixed plate 91 fixedly installed on the opposite side of the mounting cylinder 85. A clamping screw 92 is threadedly installed on the bottom surface of the fixed plate 91. An upper clamping block 93 is movably installed at the bottom end of the clamping screw 92, and the middle part of the upper clamping block 93 is V-shaped. A lower clamping block 94 is fixedly installed on the opposite side of the mounting cylinder 85, and the upper clamping block 93 is located on the top surface of the lower clamping block 94. The upper clamping block 93 and the lower clamping block 94 are matched in size. The top end of the clamping screw 92 is threaded through the bottom surface of the fixed plate 91 and extends to the outside of the fixed plate 91.

[0025] The upper clamping block 93 and the lower clamping block 94 can clamp parts of different sizes. When in use, place the part on the top surface of the lower clamping block 94, and then rotate the clamping screw 92 to drive the upper clamping block 93 to clamp the part through the lower clamping block 94. The upper clamping block 93 and the lower clamping block 94 are both V-shaped, which can clamp cylindrical parts, making it very practical.

[0026] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0027] In use, the user connects the device to power, then starts the DC motor 6 according to the size of the part, driving the forward and reverse screws 3 to move the mounting plate 5 laterally through the slider 4 to adjust it to a suitable position. Then, the DC motor 6 is turned off, and the part is placed on the top surface of the lower clamping block 94. Next, the clamping screw 92 is rotated, driving the upper clamping block 93 to clamp the part through the lower clamping block 94. Then, the adjusting screw 86 is rotated, driving the movable disk 811 to rotate and push it towards the clamping mechanism 9. At this time, the clamping mechanism 9 makes the part rotate for fastening assembly. Then, the limiting screw 81 is rotated, driving the limiting block 83 to lock into the limiting groove 84 to fix the position of the movable disk 811. Then, the part is assembled. When it is necessary to assemble the bottom surface of the part, the drive motor 87 is started, driving the gear 88 to rotate the mounting cylinder 85 through the toothed block 810. Then, the mounting cylinder 85 will drive the clamping mechanism 9 to rotate the part. After the part is flipped over, the drive motor 87 can be turned off to fix the position of the part, making it convenient for the user to assemble.
