The fixing device 2 comprises: a rotating rod 21, a gear 26, a rack 25, a fixing block 24, a first clamping block 22 and a second clamping block 23. The rotating rod 21 passes through the main body plate 1 and is rotatably connected to the main body plate 1. The end of the rotating rod 21 away from the gear 26 is connected to a torsion block 8, and the torsion block 8 is rotated to rotate the rotating rod 21 and the gear 26. The rotating rod 21 is fixedly connected to the gear 26, and the rotating rod 21 rotates to rotate the gear 26. The gear 26 is located inside the main body plate 1 and is rotatably connected to the main body plate 1. The fixing block 24 has two blocks, both of which are fixedly arranged in the main body plate 1, and the first clamping block 22 is fixedly connected to the fixing block 24. The rack 25 has two pieces, which are respectively arranged on both sides of the gear 26 and are arranged opposite to each other. The rack 25 is meshed and connected with the gear 26. The rack 25 is slidably connected with the main plate 1. The gear 26 rotates to drive the rack 25 to move. The second clamping block 23 has two pieces, which are respectively fixedly connected with the rack 25. The rack 25 drives the second clamping block 23 to move. The main plate 1 has two sides with sliding grooves 3. The second clamping block 23 extends out of the sliding grooves 3 and is slidably connected with the sliding grooves 3. The first clamping block 22 and the second clamping block 23 are connected to the ends away from the rack 25 with arc blocks 9. The arc blocks 9 are fitted with steel pipes to increase more contact surfaces to prevent the main plate 1 from slipping.

[0021] like Figures 1-2As shown, the end of the first clamping block 22 away from the gear 26 is connected to a clamping device 4 for preventing the first clamping block 22 from loosening, and the clamping device 4 includes: a rotating shaft 42, an arc plate 41, a first spiral rod 45, a first clamping block 43, a second clamping block 44 and a rotating block 46. The rotating shaft 42 is rotatably connected to the first clamping block 22, one end of the arc plate 41 is fixedly connected to the rotating shaft 42, and the arc plate 41 and the rotating shaft 42 rotate simultaneously. The first spiral rod 45 passes through the other end of the arc plate 41 and is threadedly connected to the arc plate 41, the first clamping block 43 is fixedly connected to the lower side of the arc plate 41, the first spiral rod 45 passes through the second clamping block 44 and is slidably connected to the second clamping block 44, and the second clamping block 44 and the first clamping block 43 fix the second clamping block 23. The first screw rod 45 passes through the rotating block 46 and is threadedly connected to the rotating block 46 . The rotating block 46 is rotated to lower the rotating block 46 , and the second clamping block 44 moves downward to contact the second clamping block 23 .

The second threaded rod 7 is penetrated with a rotating plate 6 and is threadedly connected with the rotating plate 6, and the stopper plate 5 is moved to contact the steel pipe through the rotating plate 6. The stopper plate 5 is arc-shaped to prevent contact with the arc plate 41.

[0023] The working process of the above scheme is as follows: the main plate 1 is placed between two steel pipes, at which time the first clamping block 22 fits the steel pipe. At this time, the torsion block 8 is rotated to rotate the rotating rod 21 and the gear 26, and the gear 26 drives the rack 25 to move, and the rack 25 moves the second clamping block 23 toward the steel pipe and close to the steel pipe, at which time the steel pipe is initially fixed to prevent the main plate 1 from sliding. The arc plate 41 is rotated to make the first clamping block 43 located at the lower side of the second clamping block 23, and at this time the rotating block 46 is rotated to make the second clamping block 44 descend and contact the upper end of the second clamping block 23 to prevent the second clamping block 23 from sliding. At this time, the rotating plate 6 is rotated to make the abutting plate 5 approach the steel pipe to contact the two sides of the steel pipe to reduce the pressure of the fixing device 2.
