So, then need not the people and hold the instrument and stir earth to plastic film both sides and push down it, it is more laborsaving, improved work efficiency.

When the plastic film moves to the ground, an operator can push the T-shaped rod 105 to move downwards, the T-shaped rod 105 moves downwards to drive the fixture block 15 to move downwards through the movable rod 13, the fixture block 15 moves downwards to drive the sleeve 104 to move downwards through the clamping groove 12, the sleeve 104 moves downwards to drive the plastic film to move downwards into the ground, when the plastic film moves downwards to a proper position, the upper portions of the left and right movable rods 13 can be pulled to swing inwards, the upper portions of the left and right movable rods 13 swing inwards to enable the lower portions to move outwards, the fifth spring 14 is stretched, the lower portion of the movable rod 13 swings outwards to drive the fixture block 15 to swing outwards, the fixture block 15 swings outwards to be separated from the clamping groove 12, the T-shaped rod 105 can be continuously pushed to move downwards to drive the wedge block 107 to move downwards, and the push rod 109 can move outwards to push part of the plastic film into the ground. When the T-shaped rod 105 moves upward to reset, the movable rod 13 can be released, and due to the action of the fifth spring 14, the lower portion of the movable rod 13 swings inward to drive the fixture block 15 to swing inward and insert into the fixture groove 12, and the fixture block 15 is matched with the fixture groove 12 to fix the movable rod 13, so that the T-shaped rod 105 is fixed. Therefore, the T-shaped rod 105 does not need to be pushed after the sleeve 104 is pushed to move downwards, and the operation is more convenient.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made herein without departing from the principles and spirit of the invention as defined by the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the remainder of the disclosure, but rather to limit the scope of the disclosure to the full extent set forth in the appended claims.
