First, people place six movable socket shells in an orderly manner between the support block 6 and the upper side of the first protective plate 92, so that the lowermost mobile socket shell is aligned with the slot on the first protective plate 92, so that The positioning effect is achieved, and then the moving block 83 moves to the left to drive the pressing block 96 to move to the left. When the pressing block 96 moves to contact with the raised part of the pulling plate 95, the pressing block 96 drives the pulling plate 95 and the second slide bar 93 moves downwards, so that the first protective plate 92 moves downwards away from the movable socket housing, and the second spring 94 is compressed. When the trimming tool 4 completes the initial trimming of the movable socket housing, people control the output shaft of the motor 81 to reverse Rotate, thereby make screw mandrel 82 counter-rotate, make moving block 83 and first guide bar 84 move to the right, briquetting block 96 moves to the right, and then trimming tool 4 moves to the right and trims the mobile socket housing again, when When the pressing block 96 moves to the groove portion of the pull plate 95, the second spring 94 resets and drives the second slide bar 93 and the first protective plate 92 to move upward, thereby causing the pull plate 95 to move upward. At this moment, the first protective plate 92 and the first protective plate 92 The lowermost movable socket shell is in contact, and when trimming tool 4 completes the trimming of the movable socket shell, people turn off the motor 81 and the trimming cutter 4, and then people rotate the movable socket shell according to the above-mentioned steps, and the unrepaired part of the movable socket shell is removed. The two sides are located at the front and rear sides. After the rotation is completed, people manually move the first sliding frame 3, so that the edge trimming tool 4 moves. When the edge trimming tool 4 moves to a suitable position, people stop moving the first sliding frame 3, and then people press The above steps start the motor 81 and the edge trimming tool 4, so that the edge trimming tool 4 trims the mobile socket shell again. After people close the motor 81 and the edge trimming tool 4 according to the above steps, people take out the mobile socket shell that has been trimmed. That's it.

People place the shells of the six mobile sockets in an orderly manner between the support block 6 and the upper side of the first protective plate 92, and are located on the lower side of the two mounting brackets 101. When the pressing plate 74 compresses the shells of the six mobile sockets, people First, the clamping block 105 is manually rotated, so that the first rotating shaft 104 rotates, and the torsion spring 106 is twisted and deformed. Then, people place the limiting block 102 on the mounting frame 101 on the same side according to the width of the mobile socket shell, so that the limiting block 102 and the Move the socket shell to contact, and then people release the block 105, so that the torsion spring 106 resets and drives the block 105 to rotate in the reverse direction to reset, and the first rotating shaft 104 rotates in the opposite direction. At this time, the block 105 is in contact with the mounting frame 101 on the same side. So that the clamping block 105 clamps the limiting block 102 on the mounting frame 101, and now the limiting block 102 limits the movable socket housing, avoiding the movement of the movable socket housing when trimming, and when the trimming is completed, people press the The above steps manually rotate the clamping block 105. When the clamping block 105 is far away from the mounting frame 101 on the same side, people take out the limit block 102, and then people rotate the trimmed mobile socket shell according to the above steps. After the mobile socket shell is rotated , people place the limit block 102 according to the above steps.

When people need to move the first sliding frame 3 to the outside according to the width of the mobile socket housing, people manually move the first sliding frame 3 on the front side to the outside, so that the rack 111 on the front side moves to the outside, so that the second rotating shaft 112 And the spur gear 113 rotates, and now the rack 111 on the rear side moves to the outside, and then the first sliding frame 3 on the rear side moves to the outside. When people need to move the first sliding frame 3 to the inside, people manually move the front to the inside. The first sliding frame 3 on the side, so that the rack 111 on the front side moves to the inside, so that the second rotating shaft 112 and the spur gear 113 rotate in the opposite direction. At this time, the rack 111 on the rear side and the first sliding frame 3 on the rear side Moving to the inside realizes the effect of adjustment and reduces the operation of people adjusting the position of the first sliding frame 3 many times.

When people need to place the shell of the mobile socket, people manually move the second protective plate 124 upwards, so that the second protective plate 124 moves upwards along the second guide bar 123, when the second protective plate 124 moves upwards and contacts with the magnet 122 , the magnet 122 magnetically attracts the second protective plate 124. At this time, people can place the mobile socket housing. After the placement is completed, people manually move the second protective plate 124 downwards, so that the second protective plate 124 moves along the second guide bar. 123 moves downwards, realized the effect of protection with this, avoided the dust that produces when trimming to fly out, when people need to take out the shell of mobile socket, people move up the second protective plate 124 according to above-mentioned operation and get final product.

Those skilled in the art can make various other corresponding changes and deformations according to the above-described technical solutions and concepts, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
