[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations, but they are not intended to limit the present invention.

[0020] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect that the utility model can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0021] like Figure 1 to Figure 2 As shown, an intermediate support of a preferred embodiment is shown, which includes: a first steel pipe 1, positive and negative screw rods 2, a second steel pipe 3, a first lifting ear 4, and a support seat 5.

[0022] A first threaded hole is opened at the upper end of the first steel pipe 1, and a second threaded hole is opened at the lower end of the second steel pipe 3. Both ends of the forward and reverse screw rods 2 are respectively installed in the first threaded hole and the second threaded hole; the end of the second steel pipe 3 away from the forward and reverse screw rods 2 is installed with a support seat 5 through two first lifting ears 4.

[0023] In actual use, the diameter of the forward and reverse screw rods 2 can be greater than 40 mm. The device can be reused many times without modifying the size before each use. It can be directly adjusted through the forward and reverse screw rods to achieve the required length, and the forward and reverse screw rods 2 can also be reused in other subsequent functions to improve utilization.

[0024] Furthermore, the first steel pipe 1 and the second steel pipe 3 have the same specifications and models and need to meet the overall force requirements. The length is selected to be 1000 mm so that it can be adjusted with the upper positive and negative screw rods 2 to reduce the forced squatting position of the personnel and enable them to operate while standing.

[0025] The utility model also has the following implementation methods based on the above:

[0026] Furthermore, an intermediate support, which also includes: a bottom plate 6: the diameter of the bottom plate 6 is larger than the diameter of the first steel pipe 1, the bottom plate 6 is installed at the bottom end of the first steel pipe 1, and a circular hole is provided in the center of the bottom plate 6. Specifically, the bottom plate 6 adopts a circular plate 50 mm larger than the diameter of the first steel pipe 1, and the wider part is used for welding of the welding feet. Since the area of ​​the bottom plate 6 is large, the bottom plate 6 can increase the contact area of ​​the bottom of the bottom plate 6 when in use, and reduce the impact of the unevenness of the bottom surface of the foundation on the support. And the thickness of the bottom plate 6 is greater than or equal to the wall thickness of the first steel pipe 1, and a circular hole with a diameter not greater than 40 mm is opened in the center of the bottom plate 6 to remove various dust, iron filings, impurities, etc. generated during use.
