When the inner sleeve 12 and the stud head are inserted together, the convex patterns and the grooves fit together, and when the inner sleeve 12 is rotated, the stud head can be twisted off from the position of the annular groove by torque.

[0034] The driving end of the motor 17 penetrates the side plate 15 and is fixedly connected with the inner sleeve 12, which is used to be plugged together with the stud head. When the inner sleeve 12 rotates, the stud head is cut off by torque;

[0035] A cavity 13 is provided at the end of the inner sleeve 12, and a spring 2 18 is fixedly connected to one side of the inner wall of the cavity 13, and a push rod 19 is fixedly connected to the other end of the spring 2 18, and the other end of the push rod 19 passes through the inner side of the cavity 13 away from the side of the spring 2 18. The inner sleeve 12 is arranged inside the outer sleeve 1, and the inner sleeve 12 only rotates inside the outer sleeve 1, and there is no connection between the inner sleeve 12 and the outer sleeve 5. The push rod 19 pushes out the stud head in the extended state, and the motor 17 drives the inner sleeve 12 to rotate in the opposite direction of the outer sleeve 1, thereby breaking the screw head, and then pulling the handle 4 on one side to remove the outer sleeve 1 from the outside of the nut, and using the spring 2 18 to push the push rod 19 to move, so as to push the screw head out from the inside of the inner sleeve 12.

[0036] A fixed cylinder 2 is rotatably connected to the inside of one end of the outer shell 5, and a conical gear ring 20 is fixedly connected to the outside of one end of the fixed cylinder 2. An outer sleeve 1 is arranged at the other end of the fixed cylinder 2. The outer sleeve 1 is directly inserted into the inside of the fixed cylinder 2. There is no connection between the outer sleeve 1 and the fixed cylinder 2. The outer sleeve 1 is used to tighten the nut. The rotation of the bevel gear 16 drives the conical gear ring 20 and the fixed cylinder 2 to rotate, and the rotation of the fixed cylinder 2 drives the outer sleeve 5 to rotate, thereby tightening the nut.

[0037] A mounting seat 9 is fixedly connected to the middle of the bottom end of the outer shell 5, and a motor 22 is fixedly connected to the inner top wall of the mounting seat 9. The driving end of the motor 22 passes through the outer shell 5 and is fixedly connected to a bevel gear 16. The bevel gear 16 is meshed and connected to the bottom end of the bevel gear ring 20. The bevel gear 16 is used to drive the fixed cylinder 2 to rotate. The bevel gear 16 is driven to rotate by the motor 22. The rotation of the bevel gear 16 drives the bevel gear ring 20 and the fixed cylinder 2 to rotate. The rotation of the fixed cylinder 2 drives the casing of the outer shell 5 to rotate, thereby tightening the nut.

[0038] Grooves 14 are provided on both the front and rear sides of one end of the outer sleeve 1 close to the fixed cylinder 2, and the inner side walls of the two grooves 14 are fixedly connected with springs 10, and the other ends of the two springs 10 are fixedly connected with protrusions 11, and the other ends of the two protrusions 11 respectively penetrate the front and rear sides of the fixed cylinder 2. The protrusions 11 fix the outer sleeve 1 in the extended state, and the sleeve of the outer shell 5 is extended into the interior of the fixed cylinder 2, and the springs 10 are used to push the protrusions 11 out of the grooves 14 and penetrate the fixed cylinder 2, so as to fix the outer sleeve 1.

[0039] A fan 21 is fixedly connected to one side of the inner wall of the shell 5. The fan 21 is used to cool the electrical components inside the shell 5. When the electrical components inside the shell 5 are running, the fan 21 can be started to transport the air outside the shell 5 to the inside of the shell 5, and blow the air onto the surface of the electrical components for cooling.

[0040] A handle 4 is fixedly connected to one side of the bottom end of the shell 5, and a connecting wire 8 is fixedly connected to the bottom end of the handle 4. The connecting wire 8 is used to supply power to the electrical components inside the shell 5. The connecting wire 8 is connected to the power supply device, and the connecting wire 8 is used to transmit power to the electrical components inside the shell 5, so that the electrical components can start running.

[0041] The outer sides of the top of the mounting seat 9 are fixedly connected with hanging ears 3, and the hanging ears 3 are used to fix the connecting wire 8. When there is no need to tighten the nut, the connecting wire 8 can be wrapped around the outside of the mounting seat 9 and the end of the connecting wire 8 fixed with the plug can be clipped into the inside of the hanging ears 3 to fix the connecting wire 8.

[0042] A button 6 is fixedly connected to one side of the top of the handle 4 , and a rubber sleeve 7 is fixedly connected to the outer side of the handle 4 . When the staff holds the handle 4 for a long time, the rubber sleeve 7 can increase the comfort of the staff's hand.

[0043] Working principle: when the screw needs to be tightened, the nut can be sleeved onto the outside of the screw, then the handle 4 is held by the hand and the outer sleeve 1 is sleeved onto the outside of the nut, and at the same time, the inner sleeve 12 is sleeved onto the outside of the screw head and the motor 22 is used to drive the bevel gear 16 to rotate. The rotation of the bevel gear 16 drives the conical gear ring 20 and the fixed cylinder 2 to rotate, and the rotation of the fixed cylinder 2 drives the outer casing 5 to rotate to tighten the nut. After the nut is tightened, the motor 17 can be started to drive the inner sleeve 12 to rotate in the opposite direction of the outer sleeve 1, thereby breaking the screw head, and then Pull the handle 4 to the side to remove the outer sleeve 1 from the outside of the nut, and use the spring 18 to push the push rod 19 to move and push the screw head out from the inner sleeve 12. When it is necessary to replace the outer sleeve 1 of a different type, press the protrusion 11 to retract the protrusion 11 into the groove 14, and pull the outer sleeve 1 to one side to take the outer sleeve 1 out of the fixed tube 2. Then put the outer sleeve 5 of the corresponding type into the fixed tube 2, and loosen the protrusion 11 so that the spring 10 can push the protrusion 11 out of the groove 14 and penetrate the fixed tube 2 to fix the outer sleeve 1.
