[0027] It should be noted that by lifting the card plate 29 upward, the card plate 29 slides along the limit rod 202, and then the handle 24 is pulled outward, driving the slide rod 26 to move outward, thereby compressing the spring 27. When the top plate 25 is located below the card plate 29, the card plate 29 is released, so that the card plate 29 slides over the top plate 25 to block the top plate 25. Then, the two pressure steel pipe bodies 3 are placed above the support seat 1 and are respectively located on the left and right parts of the support seat 1. By starting the electric telescopic rod 201, the electric telescopic rod 201 is driven to The connecting rod 21 moves upward, thereby driving the four ejection plates 22 to move upward, thereby lifting the pressure steel pipe body 3 upward. When the axis center of the pressure steel pipe body 3 and the axis center of the top plate 25 are at the same level, the electric telescopic rod 201 is stopped. At this time, the clamping plate 29 is lifted upward again. Under the action of the spring 27, the top plate 25 moves to the middle position, thereby pushing the two pressure steel pipe bodies 3 to the middle position, so that the opposite ends of the two pressure steel pipe bodies 3 are close to each other, achieving a better positioning effect.

[0028] like Figure 2 As shown, four slide grooves 20 are provided on the top of the support seat 1 , and the sizes of the four slide grooves 20 are all larger than the lower size of the ejection plate 22 .

The threads at both ends of the bidirectional threaded rod 45 are set in opposite directions. Since the bidirectional threaded rod 45 is threadedly connected to the two threaded blocks 46, the two threaded blocks 46 are driven to move to the middle position, and then the two clamping plates 43 are driven to move to the middle, so that the middle position of the two pressure steel pipe bodies 3 can be clamped. At the same time, a plurality of anti-slip strips 44 are provided on the inner side of the clamping plate 43, which will be compressed when in contact with the surface of the pressure steel pipe body 3, and then fit with the pressure steel pipe body 3, so that the pressure steel pipe body 3 will not rotate and slide, thereby achieving a better clamping effect on the pressure steel pipe body 3, and then facilitating the welding of the welding seam at the contact point of the two pressure steel pipe bodies 3, so as to achieve a better processing effect.

[0034] like Figure 4 , Figure 5 As shown, the clamping plate 43 is in the shape of an arc plate, the anti-slip strip 44 is in the shape of a semi-cylindrical block, and the inner wall diameter of the clamping plate 43 is consistent with the surface diameter of the pressure steel pipe body 3.

[0035] It should be noted that a plurality of anti-slip strips 44 are provided on the inner side of the clamping plate 43 , which will be compressed when in contact with the surface of the pressure steel pipe body 3 , and then fit with the pressure steel pipe body 3 , so that the pressure steel pipe body 3 will not rotate or slide.

[0036] The working principle of the utility model is as follows: by lifting the card plate 29 upwards, the card plate 29 slides along the limit rod 202, and then the pull handle 24 is pulled outwards, driving the sliding rod 26 to move outwards, thereby compressing the spring 27, and when the top plate 25 is located under the card plate 29, the card plate 29 is released, so that the card plate 29 slides over the top plate 25, blocking the top plate 25, and then the two pressure steel pipe bodies 3 are placed above the support seat 1 and are respectively located on the left and right parts of the support seat 1, by starting the electric telescopic rod 201, the connecting rod 21 is driven to move upwards, thereby driving the four ejection plates 22 to move upwards, thereby pushing the pressure steel pipe body 3 upwards, and when the axis center of the pressure steel pipe body 3 and the axis center of the top plate 25 are at the same level, the electric telescopic rod 201 is stopped, and the card plate 29 is lifted upwards again at this time. Under the action of the spring 27, the top plate 25 moves to the middle position, thereby The two ends of the two-way threaded rod 45 are threaded in opposite directions. Since the two-way threaded rod 45 is threadedly connected with the two threaded blocks 46, the two threaded blocks 46 are driven to move toward the middle position, and then the two clamping plates 43 are driven to move toward the middle, so that the middle position of the two pressure steel pipe bodies 3 can be clamped. At the same time, a plurality of anti-slip strips 44 are provided on the inner side of the clamping plate 43, which will be compressed when in contact with the surface of the pressure steel pipe body 3, and then fit with the pressure steel pipe body 3, so that the pressure steel pipe body 3 will not rotate and slide, so as to achieve a better clamping effect on the pressure steel pipe body 3, and then facilitate the welding operation of the welding seam at the contact point of the two pressure steel pipe bodies 3, so as to achieve a better processing effect.
