[0007] Preferably, a pull ring is fixedly connected to the top of the inner polygonal sleeve rod.

[0008] Preferably, both sides of the installation frame are provided with sliding grooves slidably matched with the limiting pressure plate.

[0009] Beneficial Effects

[0010] The utility model provides a portable retractable construction shovel. Compared with the existing technology, the utility model has the following beneficial effects: the utility model slides the inner polygon sleeve rod inside the outer rod, and sets the first outer thread sleeve and the first inner thread ring and the second outer thread sleeve and the second inner thread ring between the outer rod and the inner polygon sleeve rod, so that the length of the outer rod and the inner polygon sleeve rod can be conveniently contracted and fixed, and then the shovel head is rotated to make it easy to fold, and the occupied space is reduced again, and then a positioning mechanism is set between the inner polygon sleeve rod, the mounting frame and the rotating frame, so that when the shovel head is in use, the threaded cooperation of the inner polygon sleeve rod and the outer rod can cause the shovel head to be fixed at a corresponding angle.
