Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 7, the multi-functional hole digger of the present invention comprises a fixing member 10, a fixing ring 11 and a positioning member 12, wherein the positioning member 12 is sleeved outside the fixing member 10. The outside of mounting 10 has first locating piece 13, has spout 14 and annular 15 on the inner circle of solid fixed ring 11, and spout 14 communicates with annular 15, and solid fixed ring 11 is arranged in on first locating piece 13 through annular 15. And a second positioning block 16 is further provided outside the fixing member 10, the second positioning block 16 is located at the upper end of the first positioning block 13, and the second positioning block 16 and the first positioning block 13 are arranged at an interval. The second positioning block 16 is used for blocking the fixing ring 11 to prevent the fixing ring 11 from easily falling off. When needs take off solid fixed ring 11, rotate solid fixed ring 11 for spout 14 corresponds with first locating piece 13, then with solid fixed ring 11 rebound, after second locating piece 16 was run into to solid fixed ring 11 upper end, rotates solid fixed ring 11 again, makes spout 14 correspond with second locating piece 16, alright with solid fixed ring 11 takes off. And can be placed on the second positioning block 16, so that the second positioning block 16 is placed in the ring groove 15. The securing ring 11 is also used to secure and abut against the retainer 12.

The inner wall of the fixing piece 10 is provided with an internal thread 17, the inside of the fixing piece 10 is provided with a baffle 18, a first spring 19 and a fixing block 20, the outer wall of the fixing block 20 is provided with an external thread 21, the fixing block 20 is arranged in the fixing piece 10 in a matching mode through the external thread 21, the baffle 18 is arranged at the lower end of the fixing block 20, and the first spring 19 is arranged at the lower end of the baffle 18.
