In this embodiment, the collecting mechanism 1 includes a front plate 104, a left side plate 102, a rear plate 101, and a right side plate 103, and any adjacent two of the front plate 104, the left side plate 102, the rear plate 101, and the right side plate 103 are fixedly connected through a clamping groove 1021 to form a channel; the upper end of the front plate 104 is provided with an arc-shaped convex acquisition end 1041, the outer side surface of the rear plate 101 is provided with a rotating mechanism, and the rotating mechanism is fixedly connected with the telescopic rod 3. When the device is not needed, all components of the acquisition mechanism 1 can be disassembled, so that the space is saved and the device is convenient to carry.
More specifically, as shown in fig. 3, which is a partial enlarged view of the snap-in connection, and fig. 4, which is a side view of the components of the acquisition mechanism, the left side plate 102 and the right side plate 103 are symmetrically arranged. Two sides of the left side plate 102 and the right side plate 103 are respectively provided with a clamping groove 1021 at positions close to the front plate 104 and the rear plate 101, and the clamping groove 1021 is wide in the interior and narrow in the opening; the shapes of the edges of the front plate 104 and the back plate 101 close to the left side plate 102 and the right side plate 103 respectively are matched with the clamping groove 1021; the two side edges of the front plate 104 and the back plate 101 are respectively inserted into the corresponding slots 1021 from top to bottom, that is, the front plate 104, the left side plate 102, the back plate 101 and the right side plate 103 are fixedly connected together, so that the acquisition mechanism 1 is formed. The clamping groove type connecting structure is simple and flexible, can be assembled when in use, can be flexibly disassembled when in no use, and is convenient to store and carry. It is necessary to control the friction at the slot-type connection so that it does not slip off automatically and easily.
In this embodiment, be equipped with on the upper end outer wall of gathering mechanism 1 and encircle gather mechanism 1's recess 107, recess 107 is located in the coplanar, just be equipped with position circle 105 in the recess 107. The retainer ring 105 may be a rubber ring (e.g., rubber ring) with elasticity and high strength, or may be fastened by a nylon cable tie. Because the front plate 104, the left side plate 102, the rear plate 101, and the right side plate 103 of the collecting mechanism 1 are connected through the engaging groove 1021, when an operator holds the telescopic rod 3 to collect a sample, when a component of a force acting on the rear plate 101 in the direction of the engaging groove 1021 is larger than a frictional force between the rear plate 101 and the left side plate 102 or the rear side plate 103, the rear plate may slide along the engaging groove 1021, so that the collecting mechanism 1 may be scattered. The locating ring 105 in the groove 107 locates the front plate 104, the left side plate 102, the rear plate 101 and the right side plate 103 on the acquisition mechanism 1, which is equivalent to applying double insurance for the firmness of the acquisition mechanism 1 and avoiding the displacement of all components on the acquisition mechanism 1.
In this embodiment, the lower part of collection mechanism 1 is equipped with flat groove 106, flat groove 106 encircles collection mechanism 1's outer wall, flat groove 106 is the outside "C" shape structure of opening, be equipped with strip of paper used for sealing 5 in flat groove 106, strip of paper used for sealing 5 will the upper opening of string bag 2 with flat groove 106 compresses tightly. The shape of the seal 5 is complementary to the opening shape of the flat seal groove 106, and the seal and the flat seal groove are matched with each other, so that an effective attaching effect can be achieved. The edge part of the upper opening of the net bag 2 is embedded between the seal 5 and the flat seal groove 106, and the seal 5 and the flat seal groove 106 are mutually attached to reliably press and fix the edge part of the upper opening of the net bag 2. When the device is not needed, the seal 5 can be drawn out, so that the net bag 2 is detached from the collecting mechanism 1, and the storage and carrying are convenient. Meanwhile, when the net bag 2 needs to be replaced due to the fact that the size of the sample needing to be sampled is different or the net bag 2 is damaged, the net bag 2 can be flexibly replaced by detaching the sealing strip 5.
In this embodiment, the upper shed of string bag 2 is equipped with flexible sleeve 201, flexible sleeve 201 with flat groove 106 cooperation of sealing, flexible sleeve 201 need use high strength, stand wear and tear material in principle, can adopt nylon cloth to make up at the upper shed of string bag 2 and form, also can adopt the soft sleeve pipe of other high strengths and the upper shed fixed connection of string bag 2. The flexible sleeve 201 is provided with seal insertion holes 202, the number of the seal insertion holes 202 may be the same as the number of the seals, or two seals 5 may share one seal insertion hole 202. The seal 5 passes through the seal insertion hole 202 of the flexible sleeve 201 and engages with the flat seal groove 106. The upper opening of the net bag 2 is set to be the type of a flexible sleeve 201, the seal 5 penetrates through the seal jack 202, the flexible sleeve 201 is sleeved on the seal 5, the seal 5 is embedded into the flat seal groove 106 on the acquisition mechanism 1 to compress the flexible sleeve 201 on the acquisition mechanism 1, and therefore the reliable connection between the net bag 2 and the acquisition mechanism 1 is achieved. The design of the flexible sleeve 201 ensures that even if the seal 5 is not matched with a certain section in the flat seal groove 106, the net bag 2 is not loosened from the acquisition mechanism 1, so that the connection between the net bag 2 and the acquisition mechanism 1 is more reliable.
In this embodiment, the rotating mechanism includes a pair of fixing seats 1011 mounted on the collecting mechanism 1 and a "T" shaped rotating shaft 1012, and the "T" shaped rotating shaft 1012 is vertically disposed on the rear plate 101.
