Since the inclined surface of the block 702 fits with the inclined surface of the rack 701, when the insertion rod 4 is moving, the block 702 and the connecting block 703 move to the inside of the insertion rod 4, shortening the compression spring 11, thereby facilitating free adjustment of the length of the insertion rod 4. At the same time, the adjustment block 705 can be manually used to move the block 702 to the inside of the insertion rod 4 under the action of the pull rope 704. Otherwise, the insertion rod 4 cannot be stored in the inside of the connecting rod 3, thereby facilitating the insertion of the insertion rod 4 into the soil, enhancing the stability of the installation pipe 1, and avoiding position displacement of the installation pipe 1.

Since the inclined surface of the block 702 fits the inclined surface of the rack 701, when the insertion rod 4 is moving, the block 702 and the connecting block 703 move to the inside of the insertion rod 4, shortening the compression spring 11, thereby facilitating free adjustment of the length of the insertion rod 4. At the same time, the adjustment block 705 can be manually used to move the block 702 to the inside of the insertion rod 4 under the action of the pull rope 704, otherwise the insertion rod 4 cannot be stored in the inside of the connecting rod 3, thereby facilitating the use of the insertion rod 4 to insert into the soil, enhancing the stability of the installation pipe 1, and avoiding position displacement of the installation pipe 1.

[0032] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model.
