Detailed Description
The rare earth sampling rod of the present invention will be described in detail with reference to the accompanying drawings.
The rare feces sampling rod of the present application comprises: a barrel member 10 and a scoop member 20.
A first hollow portion 15a and a second hollow portion 15b are formed in the tubular member 10; the first hollow portion 15a and the second hollow portion 15b communicate and are each formed in a cylindrical shape; the diameter of the first hollow portion 15a is smaller than the diameter of the second hollow portion 15b; the first end of the first hollow portion 15a is closed; the second end of the first hollow portion 15a is connected to the first end of the second hollow portion 15b; the second end of the second hollow portion 15b is a first opening; the tube member 10 is formed with a second opening 12 at a first end thereof, the second opening 12 communicating with the first hollow portion 15 a.
The spoons 20 include a spoon head, a spoon stem 24 and a handle 25; the spoon head is formed at the first end of the spoon rod; a handle 25 formed at the second end of the spoon lever 24 in a flat shape to facilitate the user's grip and rotation of the spoon member 20; the spoon head comprises a bottom plate 21, a front end plate and a base 23; the bottom plate 21 is in a curved shape of an arc, the front end plate is positioned at a first end of the bottom plate 21, and the base 23 is positioned at a second end of the bottom plate 21, thereby forming a first concave space for accommodating the rare feces sample.
The spoon member 20 is inserted into the barrel member 10, the spoon head is positioned in the first hollow part 15a and can rotate in the first hollow part 15a, and the outer peripheral surface of the base 23 is closely attached to the inner peripheral surface of the first hollow part 15 a; in the standby state, the bottom plate 23 covers or blocks the second opening 12; when a sample is collected, the first concave space is opposite to the second opening 12; the handle 25 extends from the first opening of the second hollow to the outside of the barrel member 10.
