[0029] The specific operation is as follows: when the bolt needs to be screwed, the inner wall of the wrench 6 is attached to the bolt, and the second sliding seat 1002 is slid in the second adjusting slot 9 by pushing the second adjusting button 1001, which makes the supporting seat 1003 drive the ejection gear 1004 to eject from the inner side of the handle 1, and the ejection gear 1004 is engaged with the rotating chain 5. By making the ejection gear 1004 eject and engage with the rotating chain 5, the rotating chain 5 in a loose state can be tightened. The outer end of the rotating chain 5 in a loose state is just attached to the outer contour of the bolt to match the shape of the outer contour of the bolt. The tightened rotating chain 5 can be attached to the bolt after being attached to the bolt, and the wrench 6 can be attached to the bolt to clamp the bolt. At this time, the worker turns the handle 1, which can realize the screwing of the bolt. In the above operation process, the rotating chain 5 automatically attaches to the outer surface of the bolt during the tightening process, which can make the device adapt to bolts of various sizes. This can greatly improve the use range and convenience of the device. In addition, if the position of the bolt is in the corner angle or other positions where the handle 1 is interfered with rotation, the worker can place the fixing seat 1201 on the inner side of the wrench 6, which can make the clamping block 1202 engage with the positioning slot 11 to fix the fixing seat 1201 and the wrench 6. At this time, the worker adjusts the position of the ejection gear 1004, which can make the rotating chain 5 tighten and engage with the engaging gear 1203. At the same time, the worker pulls the first adjusting button 801, which can make the first sliding seat 802 drive the clamping teeth 803 to separate from the rotating gear 4, which makes the locking of the rotating gear 4 released. The size of the bolt slot 1206 is consistent with the size of the bolt to be screwed. At this time, the worker buckles the buckle seat 1205 on the outer side of the bolt, which can cover the bolt with the bolt slot 1206, and rotates the screwing handle 3, which can make the rotating gear 4 drive the rotating chain 5 to rotate. During the rotation of the rotating chain 5, the ejection gear 1004 and the engaging gear 1203 can be rotated. By making the ejection gear 1004 rotate, the ejection gear 1004 can avoid interfering with the normal rotation of the rotating chain 5 while tightening the rotating chain 5. By making the engaging gear 1203 rotate, the engaging gear 1203 can drive the dismounting seat 1204 and the buckle seat 1205 to rotate, which makes the buckle seat 1205 realize the screwing of the bolt. During the above screwing process, the device does not need to rotate the handle 1, which makes the device still be able to quickly screw the bolt when it is in a position interference position. This can greatly improve the application environment of the device. In addition, by unscrewing the screw at the top of the dismounting seat 1204, the dismounting seat 1204 can be separated from the buckle seat 1205, which makes the device replace the buckle seat 1205 of the bolt slot 1206 of different sizes to realize the screwing of the bolts of different sizes. After removing the fixing seat 1201 from the inner side of the wrench 6, the spacer 13 can be placed on the inner side of the wrench 6. When the device needs to dismount the gear, the spacer 13 is placed close to the gear, which can make the ball 14 in the spacer 13 attached to the outer wall of the gear. At this time, the tightening of the rotating chain 5 can engage with the gear.Therefore, the ball 14 is in contact with the outer wall of the gear, which makes the rotating chain 5 cooperate with the ball 14 to clamp the gear. At this time, rotating the handle 3 can drive the gear to rotate through the meshing of the rotating chain 5 and the gear, which makes the device can quickly and conveniently disassemble the gear. Through the above design, the device can flexibly disassemble various bolts and gears during mechanical maintenance, which can greatly expand the use range of the device. Due to the wide application range of the device, the replacement frequency of the equipment during mechanical maintenance can be reduced, thereby improving the efficiency of mechanical maintenance.

[0030] In summary, the adjustable automatic wrench with chain structure is used. First, when the bolt needs to be tightened, the worker makes the inner wall of the wrench head 6 in contact with the bolt, and at the same time, pushes the second adjusting button 1001 to make the second sliding seat 1002 slide in the second adjusting slot 9. This makes the supporting seat 1003 drive the ejection gear 1004 to eject from the inside of the handle 1, and makes the ejection gear 1004 mesh with the rotating chain 5. By making the ejection gear 1004 eject and mesh with the rotating chain 5, the loose rotating chain 5 can be tightened. During the process of tightening the loose rotating chain 5, the outer end can be in contact with the outer contour of the bolt to match the outer contour shape of the bolt. After the tightened rotating chain 5 is in contact with the bolt, it can cooperate with the wrench head 6 to clamp the bolt. At this time, the worker rotates the handle 1 to tighten the bolt. During the above operation process, the rotating chain 5 automatically contacts the outer surface of the bolt during the tightening process, which can make the device adapt to various sizes of bolts, which can greatly improve the use range and convenience of the device.

[0031] Then if the position of the bolt is in the position of the handle 1 exists rotating interference position, the staff will be fixed seat 1201 placed in the inside of the wrench 6, can make the clamping block 1202 and positioning groove 11 clamping to achieve the fixed seat 1201 and the fixed wrench 6, at this time the staff adjusts the position of the ejection gear 1004, can make the rotating chain 5 taut and meshing gear 1203 meshing, at the same time the staff pulls the first position button 801, can make the first sliding seat 802 drive the gear teeth 803 and rotating gear 4 separate, this makes the locking of rotating gear 4 is released, the size of bolt groove 1206 and the size of the bolt to be screwed is consistent, at this time the staff will buckle seat 1205 buckle in the bolt outside, can make the bolt groove 1206 cover the bolt, and rotate the screw handle 3, can make the rotating gear 4 drive rotating chain 5 rotation, rotating chain 5 in the process of rotation, can drive the ejection gear 1004 and meshing gear 1203 rotation, by making the ejection gear 1004 rotation, can make the ejection gear 1004 in the rotating chain 5 taut at the same time to avoid the interference to its normal rotation, and by making the meshing gear 1203 rotation, can make the meshing gear 1203 drive dismounting seat 1204 and buckle seat 1205 rotation, this makes the buckle seat 1205 can realize the screwing of the bolt, and in the above process of screwing, the device does not need to rotate the handle 1, this makes the device in the position of the position interference, still can quickly screw the bolt, this can greatly improve the applicable environment of the device, in addition, by unscrewing the screw at the top of the dismounting seat 1204, can make the dismounting seat 1204 and the buckle seat 1205 separate, this makes the device can replace the buckle seat 1205 of different size bolt groove 1206 to realize the screwing of different size bolt;

[0032] Finally, the fixed seat 1201 is removed from the inside of the wrench 6, can be placed in the inside of the wrench 6, when the device needs to be removed, by making the pad 13 close to the gear, can make the inside of the pad 13 and the outer wall of the gear, at this time the taut rotating chain 5, the taut rotating chain 5 can be engaged with the gear, at this time the ball 14 and the outer wall of the gear, this makes the rotating chain 5 with the ball 14 can be clamped to the gear, and at this time the rotating screw handle 3, can make the device through the meshing of the rotating chain 5 and the gear drive gear rotation, this makes the device can quickly and conveniently dismounting the gear, through the above design, can make the device in the process of mechanical maintenance flexible to all kinds of bolt, gear, also various pipe fittings, drill rod etc, this can greatly expand the use range of the device, due to the wide range of application of the device, this makes the mechanical maintenance process can reduce the replacement frequency of the instrument, so as to improve the efficiency of mechanical maintenance.
