The sub-cylinders 5 on both sides can only swing to the sides, and the front and rear sub-cylinders 5 can only swing forward and backward, that is, they can only swing toward the main cylinder 3 installed in the middle position of the upper side of the base plate 1. The upper ends of the main cylinder 3 and each sub-cylinder 5 are provided with hinge balls 6, and snap-in grooves 7 are provided in the middle of the lower side and on the four sides of the mounting plate 2. The articulated ball 6 is inside the card slot 7, and a universal level 8 is arranged on the front, back and both sides of the upper side of the mounting plate 2. A collar 9 is installed on the upper side of the mounting plate 2, and a support rod 10 is installed inside the collar 9 on the upper side of the mounting plate 2. The upper end of the support rod 10 is connected to a sleeve rod 11, and the upper end of the sleeve rod 11 is connected to an umbrella-shaped clamping head 13. A bottom rod 14 is inserted into the inside of the collar 9, and a plug-in groove 15 is provided on the lower side of the bottom rod 14. The support rod 10, the sleeve rod 11, the clamping head 13 and the lifting ring 12 outside the sleeve rod 11 can be inserted into the inside of the plug-in groove 15, and the lifting ring 1 2 moves upward, when the upper side of the lifting ring 12 is close to the lower side of the clamping head 13, the bevel of the clamping head 13 can be symmetrical with the bevel of the lifting ring 12 about the contact surface, and both sides of the plug-in slot 15 are provided with movable slots 16, and the movable slots 16 are provided with locking blocks 17 used in conjunction with the clamping head 13 and the lifting ring 12. The locking blocks 17 have inclined surfaces on the sides close to each other, and the inclined surfaces face downward. After the locking blocks 17 are close to each other and clamp the lower side of the clamping head 13, the bottom rod 14 cannot be pulled out at will. When the bottom rod 14 is pressed downward, the two locking blocks 17 are squeezed apart by the lifting ring 12 and clamped to the lifting ring 12. On the lower sleeve rod 11, the bottom rod 14 is pulled upward, and under the squeezing of the inclined surface of the lifting ring 12, the two locking blocks 17 move away from each other, and in the process of the bottom rod 14 moving upward, the locking blocks 17 clamp the lifting ring 12 and move upward together, until the lifting ring 12 is blocked by the clamping head 13, and the two locking blocks 17 are separated to the farthest, and then the bottom rod 14 is pulled out from the inside of the sleeve ring 9. A plurality of combination rods 19 are provided on the upper side of the bottom rod 14, and the combination rods 19 are connected together by threads. The lowest combination rod 19 is threadedly connected to the upper end of the bottom rod 14, which is convenient for assembly and storage.

[0021] The utility model has guide holes 20 on the inner side of the movable groove 16 away from each other, and the lock block 17 is installed with a guide rod 21 used in conjunction with the guide hole 20 on the inner side of the guide hole 20. A limit block 22 is installed on the upper side of the guide hole 20, and a limit groove 23 used in conjunction with the limit block 22 is opened on the upper side of the guide rod 21. The limit block 22 and the limit groove 23 can prevent the lock block 17 from rotating when it moves to both sides. The outer side of the guide rod 21 is covered with a reset spring 24 used in conjunction with the lock block 17. When the lock blocks 17 are away from each other, After that, they can automatically reset, and there is always a tendency to approach each other for clamping. The ends of the guide rods 21 that are away from each other are equipped with anti-slip blocks 25 to prevent the lock block 17 from being bounced into the inside of the plug-in slot 15 by the reset spring 24. A guide reset structure 18 is formed between the lock block 17 and the bottom rod 14. The inside of the ring 9 is provided with a spring 26 used in conjunction with the bottom rod 14 to ensure that the lock block 17 can be clamped with the clamping head 13. The lower end of the spring 26 is installed on the upper side of the mounting plate 2, and plug rods 27 are provided on the front, back and both sides of the lower side of the bottom plate 1, which is convenient for on-site installation on the ground.

[0022] When the utility model is implemented, the bottom plate is first installed on the ground through the insertion rod 27, and the bubbles inside the universal level 8 are observed through the extension and contraction of the four auxiliary cylinders 5. The cylinder on which the bubble moves is shortened or the cylinder on the opposite side is extended until the bubbles are centered. The combination rods 19 are first connected, and the bottom rod 14 is installed to the lower end of the combined combination rods 19, and the bottom rod 14 is inserted into the inside of the collar 9. The two locking blocks 17 begin to move away from each other under the pressure of the inclined surface of the top of the clamping head 13, and the spring 26 presses the bottom rod 14 upward. After the locking block 17 clamps the lower end of the clamping head 13, the installation is completed. When disassembly is required, the bottom rod 14 is first pressed downward, and the two locking blocks 17 begin to move away from each other after contacting the lifting ring 12. After moving to the bottom of the lifting ring 12, the bottom rod 14 is lifted upward, and the two locking blocks 17 begin to move away from each other under the pressure of the inclined surface of the lifting ring 12 until the two locking blocks 17 are separated from the clamping head 13.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
