[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a soil profiler with easy blade replacement, including a blade body 1, a handle mechanism 2 provided on the outer surface of the blade body 1, the handle mechanism 2 including a first clamping plate 21 and a second clamping plate 24, a groove 22 is provided on the top of the first clamping plate 21, a plurality of sliding holes 25 are provided on the inner wall of the groove 22, a plurality of fixing holes 26 are provided on the top of the second clamping plate 24, a fixing rod 27 adapted to the sliding hole 25 is fixedly connected to the inner wall of the fixing hole 26, the inner wall of the groove 22 is slidably connected to the outer surface of the blade body 1, a plurality of positioning holes 28 adapted to the fixing rod 27 are provided on one side of the blade body 1, the inner wall of the positioning hole 28 is slidably connected to the outer surface of the fixing rod 27, and a fixing mechanism 29 is provided between the outer surfaces of the first clamping plate 21 and the second clamping plate 24;

[0023] The outer surfaces of the first clamping plate 21 and the second clamping plate 24 are both provided with arc-shaped blocks 23, and the two arc-shaped blocks 23 are combined with each other to form a cylinder;

[0024] Through the above embodiments, multiple fixing rods 27 contact each other with the positioning holes 28 on the blade body 1, and the outer surface of the blade body 1 contacts the outer surface of the second clamping plate 24, thus forming a handle plate similar to one with protrusions. This handle plate is then aligned and installed with the first clamping plate 21 with grooves 22, thereby forming a handle plate that clamps the blade body 1. The first clamping plate 21 and the second clamping plate 24 are then fixed by the fixing mechanism 29, completing the fixing. At this time, the blade body 1 can be quickly removed and replaced by disassembling the fixing mechanism 29. The fixing rods 27 slide into the sliding holes 25 to prevent the first clamping plate 21 and the second clamping plate 24 from sliding out of alignment, so as to facilitate the installation and fixing of the fixing mechanism 29. The fixing rods 27 not only position the blade body 1, but also fix the blade body 1 in conjunction with the positioning holes 28 on the blade body 1 and the sliding holes 25 on the first clamping plate 21.

[0025] The fixing mechanism 29 includes a sliding shell 291, the outer surfaces of the first clamping plate 21 and the second clamping plate 24 are slidably connected to the inner wall of the sliding shell 291, a rotating groove 292 is provided on one side of the sliding shell 291, a rotating ring 293 is rotatably connected to the inner wall of the rotating groove 292, and a threaded tube 294 is fixedly connected to one side of the rotating ring 293.

[0026] Furthermore, a continuous threaded groove 295 is provided between the outer surfaces of the two arc-shaped blocks 23, and the inner wall of the threaded groove 295 is threadedly connected to the inner wall of the threaded tube 294.

[0027] Through the above embodiments, the sliding shell 291 can prevent the first clamping plate 21 and the second clamping plate 24 from moving in opposite directions. At the same time, the rotating ring 293 and the rotating groove 292 can make the rotation effect of the threaded tube 294 more stable. Furthermore, through the cooperation between the threaded tube 294 and the arc-shaped block 23, the sliding shell 291 can be fixed on the outer surface of the first clamping plate 21 and the second clamping plate 24. Since the shape of the first clamping plate 21 and the second clamping plate 24 is different from the inner wall shape of the sliding shell 291, the sliding shell 291 cannot rotate. Thus, the sliding shell 291 can better control the first clamping plate 21 and the second clamping plate 24 to drive the blade body 1 to move.

[0028] Working principle:

[0029] like Figures 1-4 As shown, in use, multiple fixing rods 27 contact the positioning holes 28 on the blade body 1, and the outer surface of the blade body 1 contacts the outer surface of the second clamping plate 24, forming a handle plate similar to one with protrusions. This handle plate is then aligned and installed with the first clamping plate 21, which has a groove 22, thus forming a handle plate that clamps the blade body 1. The handle plate is then slidably fitted onto the outer surfaces of the first clamping plate 21 and the second clamping plate 24, and fixed by the threaded tube 294 and the threaded groove 295. During disassembly and replacement, rotating the threaded tube 294 moves the sliding shell 291. After the threaded tube 294 separates from the threaded groove 295, the blade body 1 can be exposed by moving the first clamping plate 21 and the second clamping plate 24 up and down, at which point the blade body 1 can be replaced.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
