Through the setting of the wedge block 5910, in the initial state, the wedge block 5910 on the control sleeve 599 is meshed with the gear block 598, so that when the trigger ring 592 passes through the baffle, the baffle can only move in one direction, so that the trigger ring 592 is blocked by the baffle, so that it can be automatically released after the installation is completed;

[0045] In this embodiment, Figure 3 and Figure 5 As shown, the installation mechanism 5 also includes a right movable sleeve 510, the outer diameter of the right movable sleeve 510 is slidably connected to the outer wall of the power rod 52, and a plurality of hinged plates 511 arranged in an annular array are hingedly connected at equal intervals on the outer wall of the right movable sleeve 510, and the top of the hinged plate 511 is rotatably connected to a clamping plate 512, and a plurality of clamping plates 512 are arranged in an annular array about the right movable sleeve 510, and the rear ends of the plurality of clamping plates 512 are slidably connected to a cross plate 513, and the outer walls of the plurality of clamping plates 512 are provided with a placement groove 514, and the rear end of the cross plate 513 is rotated on the front end of the positioning seat 4, and through the arrangement of the cross plate 513, the clamping plate 512 can be restricted from moving vertically up and down, and the flange can be fixedly installed;

[0046] In this embodiment, Fig.11 , Fig.13 and Fig.12As shown, the tightening mechanism 6 includes a control ring 61, the outer wall of the control ring 61 is rotatably connected to the inner wall of the movable seat 3, an outer toothed ring 62 is rotatably connected to the inner wall of the control ring 61, and a plurality of meshing pinions 63 are arranged in an annular array in the inner wall of the outer toothed ring 62, and the plurality of pinions 63 are arranged in meshing with the side wall of the transmission rod 2, a rotating cylinder 64 is arranged at the top end of the outer toothed ring 62, a plurality of rotating cylinders 64 are arranged in an annular array about the center of the control ring 61, and grooves are provided in the inner walls of the plurality of rotating cylinders 64, and the plurality of rotating cylinders 64 are arranged in a hollow manner, along with the rotation of the transmission rod 2, the transmission rod 2 drives the plurality of pinions 63 to rotate, the pinions 63 drive the outer toothed ring 62 to rotate, the outer toothed ring 62 drives the rotating cylinder 64 which is fitted at the top end to rotate, and the rotating cylinder 64 synchronously drives the nut to rotate, so as to continuously tighten the screw and the nut;

[0047] In this embodiment, Fig.13 and Fig.14 As shown, the tightening mechanism 6 also includes a left movable sleeve 65, which is slidably connected to the transmission rod 2. The rear end of the clamping plate 512 on the left movable sleeve 65 is plugged with a cross plate 513 of the same structure. The cross plate 513 is rotatably connected to the movable seat 3. As the rotating sleeve 51 rotates, the rotating sleeve 51 drives a plurality of bolts to slide on the surface of the flange until the plurality of bolts move to the screw holes. At this time, the bolts are pushed into the screw holes by the springs on the mounting cylinder 55, and slide on the other flange until they are inserted into the screw holes. Similarly, when the bolts are fully inserted into the two flanges, they will slide on the surface of the control ring 61. When the screw is inserted into the rotating cylinder 64, the nut on the rotating cylinder 64 is connected to the screw.

[0048] In this embodiment, Fig.13 and Fig.15 As shown, a drum piece 66 is fixedly connected to the inner wall of the rotating cylinder 64, and the bulging direction of the drum piece 66 is to the right, and the drum piece 66 is arranged at the same level as the installation cylinder 55. Through the arrangement of the drum piece 66, after the screw rod is completely connected with the nut, the end of the screw rod will continue to be inserted into the rotating cylinder 64 until it hits the drum piece 66, producing a crisp sound, prompting the staff to complete the installation.

[0049] The use method and advantages of the present invention: The working process is as follows:

[0050] like Figures 1 to 15As shown, the staff first places a number of nuts on the rotating cylinder 64 in sequence, and then manually pushes the trigger ring 592 forward, and at the same time slightly rotates the trigger ring 592, so that the protruding surface 593 on the trigger ring 592 is separated from the sliding rod 58, and the clamping piece 595 is moved, and the clamping piece 595 squeezes the limiting rod 594, so that the limiting rod 594 moves toward the trigger ring 592 and enters the inner side of the clamping piece 595, so that the trigger ring 592 is temporarily limited in position by the clamping piece 595;

[0051] Then, the bolt is manually inserted into the interior of the installation tube 55. Due to the arrangement of the two groups of semi-ring blocks 56, the outer wall of the bolt squeezes the semi-ring block 56 to open, so that the bolt can be directly inserted into the semi-ring block 56. When the semi-ring block 56 returns to its original position through the spring telescopic rod, the bolt head is stuck in the limiting groove to limit the bolt. At the same time, when the flange is placed, the outer wall of the flange located on the positioning seat 4 will contact with the installed bolt, squeezing the tail of the bolt and pushing the installation tube 55 to squeeze the spring to move backward. At this time, since the clamping plate 512 is provided with a placement groove 514, the flange is restricted in the placement groove 514.

[0052] Then, the flange is manually placed on the clamping plates 512 on both sides, and the movable seat 3 is pushed forward. The movable seat 3 moves forward, driving the left movable sleeve 65 to move toward the right movable sleeve 510, and the left movable sleeve 65 squeezes the right movable sleeve 510, and the two slide on the transmission rod 2 and the power rod 52 accordingly. Since the two groups of clamping plates 512 are respectively connected to the left movable sleeve 65 and the right movable sleeve 510 through the hinge plate 511, when the left movable sleeve 65 and the right movable sleeve 510 slide, the clamping plates 512 can be pushed to slide on the cross plate 513. At this time, several clamping plates 512 can internally support and limit the placed flange. At this time, the screw is manually rotated to limit the position of the movable seat 3, and the clamping piece 595 is manually toggled at the same time to release the connection between the clamping piece 595 and the limiting rod;

[0053] At this time, the motor group is started. Since the transmission rod 2 and the power rod 52 are connected by a spline, the transmission rod 2 can drive the power rod 52 to move synchronously, and the two cross plates 513 are rotatably connected with the positioning seat 4 and the movable seat 3 respectively, and the transmission rod 2 and the power rod 52 are arranged through the two cross plates 513, so that the two groups of cross plates 513 do not rotate at this time. At the same time, the transmission rod 2 drives the power rod 52 to rotate, and the power rod 52 drives the rotating sleeve 51 to rotate through the pulley 53 and the toggle wheel 54 at the end;

[0054] Then, along with the rotation of the rotating sleeve 51, the rotating sleeve 51 drives several bolts to slide on the surface of the flange until the several bolts move to the screw holes. At this time, the bolts are pushed into the screw holes by the springs on the mounting cylinder 55, and slide on the other flange until they are inserted into the screw holes. Similarly, when the bolts are fully inserted into the two flanges, they will slide on the surface of the control ring 61. When the screw is inserted into the rotating cylinder 64, the nut on the rotating cylinder 64 is connected to the screw. At the same time, along with the rotation of the transmission rod 2, the transmission rod 2 drives several pinions 63 to rotate, and the pinions 63 drive the outer gear ring 62 to rotate. The outer gear ring 62 drives the rotating cylinder 64 that is fitted at the top to rotate. The rotating cylinder 64 synchronously drives the nut to rotate, and the screw and the nut are continuously tightened.

[0055] Finally, when the screw is completely tightened with the nut, the installation cylinder 55 is completely reset by the spring, and the side wall of the installation cylinder 55 squeezes the trigger rod 5912. The trigger rod 5912 pushes the telescopic lever 5911 inward, and the control sleeve 599 at the other end of the telescopic lever 5911 moves in the opposite direction. The wedge block 5910 on the control sleeve 599 separates from the gear block 598, and the restriction on the gear block 598 is released. At this time, the baffle 597 has no restriction, and the trigger ring 592 is quickly moved forward and reset by the spring. The bottom end of the trigger ring 592 squeezes the sliding rod 58, and the sliding rod 58 pushes the telescopic plate 57. The telescopic plate 57 pushes the two half-ring blocks 56 to separate, and the installation of the screw is released. At this time, the disassembly operation can be performed.

[0056] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
