The expansion process of the stabilizing support comprises the following steps: after the preparation is completed, the operator rotates the first U-shaped frame 102 around the rotating rod on the upper portion of the socket wrench 101 by driving the T-shaped handle 103, wherein during the downward rotation of the T-shaped handle 103, the outer surface of the T-shaped handle 103 contacts the arc-shaped groove of one of the door-shaped frames 204, and as the T-shaped handle 103 continues to rotate downward, the T-shaped handle 103 drives one of the door-shaped frames 204 to move downward, at this time, one of the door-shaped frames 204 drives the other two door-shaped frames 204 to move downward synchronously by the first connecting rod 205, the three first elastic members 206 are compressed downward, and at the same time, when the three door-shaped frames 204 move downward, the three door-shaped frames 204 drive one of the second connecting rods 207 to move downward, the three second connecting rods 207 move in the movable groove 208a of one of the special-shaped frames 208, the three second connecting rods 207 drive one of the frames 208 to rotate around the first rotating shaft 209, at this time, under the lever action, the three special-shaped limiting frames 208 respectively drive the support legs 202 to rotate through the pin rods 203, the lower parts of the three support legs 202 are outwards unfolded, then, an operator presses the ring support frame 1 downwards, at the moment, the positioning ring 3 abuts against the upper surface of the long pipe, the third elastic part 401 is compressed, the sectional disassembly and assembly unit and the support positioning unit are synchronously driven to move downwards, so that the socket wrench 101 contacts with the bottom of the long pipe, meanwhile, the lower parts of the three support legs 202 also abut against the ground, the ring support frame 1 is stably supported through the three support legs 202, wherein when the ring support frame 1 is pressed downwards, the ring support frame 1 drives the three clamping seats 402 to move downwards, when the three clamping keys 405 pass through the clamping grooves 402a of the clamping seats 402, at the moment, the socket wrench 101 contacts with the bottom of the long pipe, the operator manually rotates the three clamping keys 405 to stagger the three clamping keys 405 from the clamping grooves 402a, when the operator does not apply downward pressure to the ring support frame 1, the ring support frame 1 is limited by the three clamping keys 405 and cannot move upwards, after the socket wrench 101 contacts the bottom of the long pipe, the socket wrench cannot be separated from the nut due to the upward movement, the third elastic element 401 is in a compressed state, then the T-shaped handle 103 synchronously drives the three door-shaped frames 204 to move downwards in the downward rotation process, the opposite sides of the three U-shaped clamping blocks 303 cling to the surfaces of the three door-shaped frames 204 to slide, along with the downward movement of the three door-shaped frames 204, when two branch parts of the three U-shaped clamping blocks 303 are matched with the pin holes 204a, at the moment, the initial state of the second elastic element 302 is compressed, the three second elastic elements 302 start to extend, the three second elastic elements 302 respectively drive one U-shaped clamping block 303 to slide on the sliding frame 301, the three U-shaped clamping blocks 303 are close to the center direction, two branch parts of the U-shaped clamping blocks 303 are inserted into the two pin holes 204a of each door-shaped frame 204, at this moment, T shape handle 103 has rotated the right angle downwards, for avoiding operating personnel to use the injury that the irregularity leads to, blocks three door-shaped frame 204 through three U-shaped fixture block 303, avoids T shape handle 103 to rotate downwards excessively, simultaneously through blocking three door-shaped frame 204 the back, three stabilizer blade 202 can be more firm to ring support frame 1.
The automatic feeding process of the nut comprises the following steps: an operator puts a plurality of nuts into the socket wrench 101 in advance, when the operator controls the T-shaped handle 103 to rotate downwards, the T-shaped handle 103 drives the first U-shaped frame 102 to rotate, the first U-shaped frame 102 rotates to drive one L-shaped rod 502 to move downwards, after the two L-shaped rods 502 are connected through the annular frame 503, the two L-shaped rods 502 move synchronously, at the moment, the two fourth elastic members 501 are compressed, the two L-shaped rods 502 move downwards in the socket wrench 101, the two L-shaped rods 502 respectively drive one baffle 505 to rotate downwards around the second rotating shaft 504, after the two baffles 505 are received in the two straight grooves 101b, the heads of the nuts are not limited by the two baffles 505, and the nuts fall downwards until the bottoms of the nuts contact the positions of the screw holes.
The nut installation process: after the operation is completed, the T-shaped handle 103 and the socket wrench 101 are in a perpendicular state, at this time, an operator can rotate the T-shaped handle 103 by using the center of the socket wrench 101 as an original point by stirring the T-shaped handle 103, the T-shaped handle 103 drives the first U-shaped frame 102 to drive the socket wrench 101 to rotate in the fixing barrel 2, the nut is driven to rotate by rotating the socket wrench 101, the nut is screwed into the screw hole, and after the nut is screwed into the screw hole, the operator stops stirring the T-shaped handle 103.
And (3) nut installation ending stage: after the nut is installed, firstly, an operator rotates the T-shaped handle 103 upwards to enable the centers of the T-shaped handle 103 and the socket wrench 101 to be in the same straight line, at this time, the two fourth elastic members 501 extend to synchronously drive the two L-shaped rods 502 to move upwards, after the two L-shaped rods 502 are respectively separated from one baffle 505, the two baffles 505 are reset under the action of the torque spring, the two baffles 505 are clamped in the middle hexagon nut limiting groove 208b of the socket wrench 101 to limit subsequent nuts so as to prevent the subsequent nuts from falling off, then, the operator rotates the three clamping keys 405 to enable the three clamping keys 405 to be matched with the three clamping grooves 402a, at this time, the third elastic member 401 recovers, the third elastic member 401 drives the ring support frame 1 to move upwards to enable the lower part of the socket wrench 101 to leave the bottom of the long pipe, then, the operator pulls the limiting rod 304 towards the side far away from the door-shaped frame 204, three gag lever post 304 respectively drives a U-shaped fixture block 303 and moves toward the direction of keeping away from each other for three U-shaped fixture block 303 withdraws from in the pinhole 204a of door shape frame 204, the spacing back of relieving of three door shape frame 204 this moment, three first elastic component 206 resumes, three first elastic component 206 drives door shape frame 204 and up moves, drive three stabilizer blade 202 lower part in step and draw in, the supporting effect is relieved this moment, portable T shape handle 103 of operating personnel's accessible, upwards mention this two-stage type replacer, make box spanner 101 withdraw from the hose, and transfer on next position that needs the fitting nut.
The dismounting process of the nut comprises the following steps: similar to the installation process of the nut, an operator puts the socket wrench 101 of the two-section replacer into the long pipe through the T-shaped handle 103, after the T-shaped handle 103 is rotated downwards and the support is stabilized, the operator also pulls the T-shaped handle 103, the socket wrench 101 screws the nut out of the screw hole of the long pipe, the screwed nut is limited by the hexagon nut limiting groove 208b in the socket wrench 101, then the T-shaped handle 103 is rotated upwards, so that the T-shaped handle 103 and the socket wrench 101 are in the same vertical state, at the moment, the two fourth elastic members 501 restore to be extended, after the two L-shaped rods 502 do not contact with the baffles 505, the two baffles 505 are reset under the action of the torsion spring, the two baffles 505 are clamped in the hexagon nut limiting groove 208b, the nut which enters the hexagon nut limiting groove 208b, the head is supported by the two baffles 505, and then the operator lifts the T-shaped handle 103 upwards, allowing the socket wrench 101 to be withdrawn from the long tube.
