DETAILED DESCRIPTION

[0021] An embodiment of the application will be described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figures 1-4The utility model provides a portable geological sample collection shovel, which comprises a shovel head 1, a shovel rod 2 arranged at the top end of the shovel head 1 and a handle 3 sleeved with the shovel rod 2; the shovel head 1 comprises a shovel body 10 and a shovel head mounting cylinder 11 fixed at the top end of the shovel body 10, the inner wall of the shovel head mounting cylinder 11 is provided with a fixing hole 12, the shovel rod 2 comprises a plurality of rod bodies 22 and locking heads 20 arranged at the bottom of each rod body 22, the top end of each rod body 22 is fixed with a shovel rod mounting cylinder 24, the structure of the shovel rod mounting cylinder 24 is similar to that of the shovel head mounting cylinder 11, and the shovel rod mounting cylinder 24 is convenient for being locked with the corresponding locking head 20; the shovel head mounting cylinder 11 and the shovel rod mounting cylinder 24 are detachably connected with the locking head 20, and the above-mentioned arrangement can realize the connection of the rod body 22 with the shovel head 1 and the connection of the shovel rod 2 with the rod body 22; the middle part of the rod body 22 is inserted with an unlocking rod 21, the locking head 20 comprises a locking body 200, a plurality of latches 201 distributed in the circumferential direction of the locking body 200, an elastic element A 203 arranged on the latch 201, the outer side of the latch 201 is an inclined surface, so that the unlocking rod 21 does not need to be pressed during assembly, and the assembly process is more convenient, one end of the elastic element A 203 is fixed with the latch 201, the other end of the elastic element A 203 is fixed with a fixing column 202, the fixing column 202 is fixed in the locking body 200, each latch 201 is provided with a slide 207, an unlocking element 205 corresponding to the locking body 200 is arranged above the slide 207, the unlocking element 205 is fixed with an unlocking tooth 206 corresponding to the slide 207, the abutting surfaces of the unlocking tooth 206 and the unlocking element 205 are arranged in an inclined manner, through the above-mentioned connection, when disassembling, the unlocking tooth 206 on the unlocking element 205 pushes the latch 201 to move backward, so that the latch 201 is separated from the latch hole in the shovel rod mounting cylinder 24 or the shovel head mounting cylinder 11, and the disassembly of the rod body 22 is realized; when the plurality of rod bodies 22 are connected, the unlocking rods 21 in the rod bodies 22 abut against each other, through the above-mentioned connection, when disassembling the plurality of rod bodies 22, only the unlocking rod 21 at the uppermost end needs to be pressed to realize the one-time disassembly of the whole shovel rod 2, so that the disassembly process is simplified, the shovel body 10 is provided with a through slot, the inner wall of the shovel head mounting cylinder 11 is provided with a plurality of fixing holes 12 corresponding to the latches 201, the plurality of fixing holes 12 are distributed in the circumferential direction of the inner wall of the shovel head mounting cylinder 11, and the plurality of fixing holes 12 can improve the firmness of the fixation between the shovel head 1 and the shovel handle 2.

[0023] Please refer to Figure 5The two sides of the rod body 22 are provided with a plurality of handle fixing holes 23, which are uniformly distributed along the axial direction of the rod body 22. The handle 3 comprises a handle body 30, and the left and right sides of the handle body 30 are provided with handles. The end of the handle close to the handle body 30 is provided with an unlocking trigger 31. The top end of each unlocking trigger 31 is provided with a limiting pin 32. The abutting surfaces of each unlocking trigger 31 and the limiting pin 32 are obliquely arranged. One side of each limiting pin 32 is fixed with an elastic element B 33. The handles on the two sides of the handle body 30 are in a cylindrical structure. The hollow cavity of the handle body 30 is matched with the shovel rod 2. When the unlocking trigger 31 is not pressed, the limiting pin of the limiting pin 32 is transversely arranged in the handle fixing hole 23, so as to realize the fixation of the handle 3. When the unlocking trigger 31 is pressed, the unlocking trigger 31 drives the limiting pin 32 to rotate, so that the limiting pin is separated from the handle fixing hole 23, thereby enabling the handle 3 to move up and down.

[0024] In summary, the installation process of the portable geological sample collection shovel is that the rod body 22 is directly inserted into the shovel head mounting cylinder 11 through the locking head 20. After being inserted to a reasonable position, the bolt 201 is automatically inserted into the fixing hole 12, thereby realizing the fixation of the shovel rod 2 and the shovel head 1. The middle hole of the handle body 30 is aligned with the rod body 22, and the unlocking trigger 31 is pressed by both hands. After the handle 3 is adjusted to a suitable position, the unlocking trigger 31 is released. The elastic element B 33 is automatically inserted into the handle fixing hole 23, thereby realizing the fixation of the handle 3 on the shovel rod 2 and completing the assembly of the collection shovel. If the length of the shovel rod 2 is not enough at this time, another rod body 22 can be taken out, and the locking head 20 of the rod body 22 is inserted into the shovel rod mounting cylinder 24 of the previous rod body 22, thereby realizing the lengthening of the shovel rod 2. If the length is still not enough, the above process can be repeated multiple times until the length is appropriate. If the fixed position of the handle 3 is not suitable during use, the unlocking trigger 31 can be pressed to adjust the position, thereby achieving the best use effect. When the collection shovel is disassembled, because the unlocking rods 21 in the rod bodies 22 abut against each other when the multiple rod bodies 22 are connected, the uppermost unlocking rod 21 can be pressed to realize the one-time disassembly of the whole shovel rod 2, thereby simplifying the disassembly process.

[0025] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to this, and various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection range of the present application.
