[0021] A first slide groove 10 is provided on the inner side of the support seat 7, and the sliding mechanism 8 includes a first slider 801 provided on the inner side of the first slide groove 10. The top view appearance structure of the first slider 801 is an "I" shape, and the outer side surface of the first slider 801 close to the central axis of the base 1 is in contact with the inner side surface of the first slide groove 10, so that the first slider 801 will not shake or rotate when moving on the inner side of the first slide groove 10. The upper end of the first slider 801 is internally threadedly connected with a threaded rod 802, and a first groove 803 is provided on the inner side of the first slider 801. A baffle 804 is provided on the inner side of the first groove 803, and the outer side surface of the baffle 804 close to the end of the cylinder 2 is in contact with the inner side surface of the first groove 803, and the appearance structure of the baffle 804 close to the end of the cylinder 2 is a rectangular parallelepiped, so that the baffle 804 will not rotate or shake when moving on the inner side of the first groove 803. 04 is fixedly connected with a spring 805 on the side close to the cylinder 2, and the connection mode of the spring 805 and the first slider 801 is a fixed connection, and the end of the first connecting plate 5 away from the cylinder 2 is fixedly connected with a push plate 806, and the lower surface of the first groove 803 is connected with a third hole 807, and the inner side of the third hole 807 is provided with a first elastic telescopic rod 808, and the connection mode of the first elastic telescopic rod 808 and the baffle 804 is a fixed connection, and the end surface of the baffle 804 away from the cylinder 2 is an inclined surface, and the width of the baffle 804 is greater than the width of the third hole 807, so that the baffle 804 can move left and right along its inclined edge when it hits the steel pipe, and the length of the push plate 806 is greater than the length of the extrusion plate 6, and the side surface of the push plate 806 close to the cylinder 2 and the side surface of the extrusion plate 6 close to the cylinder 2 are on the same plane, so that the push plate 806 can move through the range of the support seat 7 before the extrusion plate 6.

[0022] The elastic mechanism 9 includes a first support plate 901 arranged below the base 1, a second slide groove 902 is arranged on the inner side of the first support plate 901, a second slider 903 is arranged on the inner side of the second slide groove 902, the second slider 903 is connected to the first elastic telescopic rod 808 in a fixed connection, the lower end width of the second slider 903 is greater than the upper end width of the second slider 903, second holes 905 are arranged inside the two sides of the base 1, the first elastic telescopic rod 808 is nested in the inner side of the second hole 905, a second support plate 906 is fixedly connected to the inner side of the first support plate 901, the second support plate 906 is fixedly connected to the base 1 through the second elastic telescopic rod 907, the elastic force of the first elastic telescopic rod 808 is greater than the elastic force of the spring 805, and the elastic force of the second elastic telescopic rod 907 is greater than the elastic force of the first elastic telescopic rod 808, so that when the second elastic telescopic rod 907 is pulled, the first elastic telescopic rod 808 can be pulled, and when the spring 805 is pushed, the first telescopic rod 808 will not be pushed.

[0023] When the height of the baffle 804 needs to be adjusted, the steel pipe is placed above the support seat 7. Since the end surface of the baffle 804 away from the cylinder 2 is an inclined surface, the steel pipe pushes the baffle 804 to move, and the threaded rods 802 on both sides are loosened, so that the threaded rods 802 lose the limit on the first slider 801, and push the second support plate 906 and the first support plate 901 to move upward, driving the second slider 903 and the first elastic telescopic rod 808 to move upward, so that the baffle 804 and the first slider 801 move upward. When the baffle 804 moves out of the range of the steel pipe, the spring 805 pushes the baffle 804 to move to the left, and the second elastic telescopic rod 808 is loosened. Rod 807 drives the first elastic telescopic rod 808 and baffle 804 to move downward, so that the baffle 804 is fitted on the top of the steel pipe. Because the first elastic telescopic rods 808 on both sides are not limited to each other, the baffles 804 on both sides can adapt to steel pipes of different diameters. The threaded rod 802 is rotated to keep the vertical positions of the baffle 804 and the first slider 801 fixed, which is to adapt from a small steel pipe diameter to a large steel pipe diameter, and from a large steel pipe diameter to a small steel pipe diameter. The threaded rods 802 on both sides are loosened, and under the action of the first elastic telescopic rod 808, the baffle 804 can be fitted on the upper surface of the steel pipe, thereby achieving the goal of adapting to steel pipes with different overall diameters.
