[0026] A lower shell 5 is provided in the middle of the upper surface of the base body 1, and protrusions 52 provided on both sides of the outer side surface of the lower shell 5 are clamped on both sides of the base body 1 to prevent the lower shell 5 from rotating at the upper end of the base body 1. A slide groove 53 is provided on the upper surface of the lower shell 5, and a slide plate 54 is slidably connected in the slide groove 53. The upper surface of the slide plate 54 is flush with the upper surface of the lower shell 5, which is convenient for the end of the shield machine to drive the slide plate 54 to slide on the slide groove 53, thereby reducing the wear of the end of the shield machine and facilitating the transportation of the end of the shield machine. The upper end of the lower shell 5 is fixed with an upper shell 51 by bolts, and a fixing seat 3 is fixed on the left and right sides of the front end of the base body 1.

The upper end of the clamping block 44 is in the shape of a circular arc with four petals separated, and the inner cavity of the clamping block 44 is spherical, which is convenient for the lower end of the moving rod 43 to move from the clamping block 44 to the circular groove 42, so as to facilitate the loosening of the upper plate 4, thereby facilitating the disassembly of the lower shell 5 and the upper shell 51, and at the same time facilitating the installation of the clamping plate 34 and the upper plate 4 on the side ends of the lower shell 5 and the upper shell 51.

[0027] The practical steps of the present invention are as follows: during actual work, a base body 1 is provided at the upper end of the base, and a support rod 11 fixed on the lower surface of the base body 1 supports the base body 1. A plurality of wedge blocks 12 are fixed to the lower ends of both sides of the base body 1 and the lower ends of the support rods 11, so that the base body 1 can be conveniently fixed to the upper end of the base through the wedge blocks 12, thereby preventing the base body 1 from shaking. Two groups of support components 2 are provided on both sides of the support rods 11, so as to increase the supporting force of the base body 1 and protect the safety of the shield machine. The support components 2 include a short plate 21 and a long plate 24. Circular holes 25 are provided at both ends of the short plate 21 and the long plate 24, and rotating shafts 23 are passed through the circular holes 25. Two mutually staggered holes are provided at one end of the hinged connection of the short plate 21 and the long plate 24. The notch 22 is opened to facilitate the connection between the short plate 21 and the long plate 24, and to facilitate the rotation between the short plate 21 and the long plate 24. Both ends of the rotating shaft 23 passing through the outer ends of the short plate 21 and the long plate 24 are hinged with limit blocks 26. The limit blocks 26 on both sides of the short plate 21 are fixed on both sides of the lower surface of the base body 1, and the limit blocks 26 on both sides of the long plate 24 are fixed on the sides of the support rod 11. A triangular support is formed by the short plate 21, the long plate 24 and the base body 1, thereby increasing the supporting force in the middle of the base body 1 and reducing the shaking of the base body 1, thereby facilitating increasing the stability of the shield machine. A lower shell 5 is provided at the upper end of the base body 1, and protrusions 52 are provided on both sides of the outer side of the lower shell 5 to prevent the lower shell 5 from rotating at the upper end of the base body 1. The upper surface of the lower shell 5 is provided with a slide groove 53 in which a slide plate 54 is slidably connected. The upper surface of the slide plate 54 is flush with the upper surface of the lower shell 5, which is convenient for the end of the shield machine to rest against the upper end of the slide plate 54, so that the slide plate 54 is driven by the end of the shield machine to slide on the slide groove 53, thereby reducing the wear of the end of the shield machine and facilitating the transportation of the end of the shield machine. The upper end of the lower shell 5 is fixed with an upper shell 51 by bolts, and the split lower shell 5 and upper shell 51 are sleeved on the outside of the shield machine to ensure that the shield machine arrives smoothly in the correct posture. The front end of the base body 1 is fixed with a fixed seat 3 on both sides, and the upper surface of the fixed seat 3 is fixed with two fixed blocks 31. The fixed block 31 is hinged at the two ends of the round rod fixed at the lower end of the telescopic rod 32, which is convenient for the rotation of the telescopic rod 32. The end of the support rod 33 fixed at the upper end of the telescopic rod 32 is fixed to the outer side of the clamping plate 34, which is convenient for increasing the supporting force of the support rod 33 through the two horizontal rods of the support rod 33. The upper plate 4 is clamped in the square groove 35 opened at the upper end of the clamping plate 34, and is clamped on the side ends of the lower shell 5 and the upper shell 51 through the upper plate 4 and the clamping plate 34, so as to facilitate the clamping of the lower shell 5 and the upper shell 51. At the same time, through the extension and contraction of the telescopic rod 32, the clamping plate 34 abuts against the front end of the lower shell 5 to prevent the shield machine from moving toward the front end of the lower shell 5 and driving the lower shell 5 to move forward, thereby affecting the installation of the shield machine. The through hole 41 opened in the middle of the vertical rod of the upper plate 4 is penetrated by a moving rod 43, and the thread on the upper end of the moving rod 43 is convenient for fixing the moving rod 43 at the opening of the through hole 41.At the same time, the ball at the lower end of the moving rod 43 is clamped in the inner cavity of the upper end of the clamping block 44, and the clamping block 44 is fixed in the middle of the bottom of the square groove 35. The moving rod 43 is fixed in the inner cavity of the clamping block 44, which facilitates the upper plate 4 to be fixed on the upper end of the clamping plate 34, so that the upper plate 4 is conveniently pressed against the upper side of the upper shell 51, and the lower shell 5 and the upper shell 51 are fixed more tightly. At the same time, the moving rod 43 is rotated to move the moving rod 43 upward, so that the lower end of the moving rod 43 moves from the clamping block 44 to move in the circular groove 42, which facilitates the loosening of the upper plate 4, thereby facilitating the disassembly of the lower shell 5 and the upper shell 51, and at the same time facilitates the installation of the clamping plate 34 and the upper plate 4 on the side ends of the lower shell 5 and the upper shell 51.
