Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The specific embodiment of the utility model provides a certificate is gathered with being stained with and is got stick, it can but not be restricted to draw the certificate for the legal medical expert and use.

As shown in fig. 1 and 2, the certificate collecting stick according to the embodiment of the present invention comprises a tube assembly 1, a cotton thread head 2 and a water bag 3. The tube assembly 1 is a hollow structure, the cotton thread head 2 is arranged at the front end of the tube assembly 1 and communicated with the tube assembly 1, the water bag 3 contains water, the water bag 3 is arranged at the rear end of the tube assembly 1, the water bag 3 is configured to be broken under pressure when external force extrudes the rear end of the tube assembly 1, and therefore the water in the water bag 3 flows into the front end of the tube assembly 1 from the rear end of the tube assembly 1 to wet the cotton thread head 2. The water bag 3 is preferably made of a plastic film, such as a polyethylene film or a polyvinyl chloride film.

Because the water bag 3 which can be broken when needed is arranged in the rear end of the tube component 1 in advance, the cotton thread head 2 is wetted by the water in the water bag 3, the operation is simple and convenient, and the water quantity in the water bag 3 can be preset, so that the water quantity in the water bag 3 is matched with the water quantity required for wetting the cotton thread head 2, the problem that the cotton thread head 2 is too much or too little in water is avoided, and the wetting effect is better.

In order to facilitate the placement of the water bag 3 and the application of pressure to the water bag 3, the tube assembly 1 includes a tube body 11 and a flexible cap 12 disposed at the rear end of the tube body 11, the water bag 3 is accommodated in the flexible cap 12, the flexible cap 12 can be deformed to further press the water bag 3 to be broken when being pressed by an external force, and the flexible cap 12 can protect the water bag 3 when not being pressed by the external force. It is understood that the flexible cap 12 is flexible in this embodiment, which means that the flexible cap 12 can be deformed when being squeezed by a hand, and the material of the flexible cap 12 can be rubber or plastic material, which can protect the water bag 3 when not being squeezed by a hand, and can deform and break the water bag 3 when being squeezed by a hand. The tube body 11 is preferably, but not limited to, made of a plastic material. The hardness of the flexible cap 12 is preferably less than the hardness of the tube body 11. The flexible cap 12 and the tube main body 11 may be detachably connected, for example, the flexible cap 12 is directly sleeved on the rear end of the tube main body 11, and the inner diameter of the portion of the flexible cap 12 for sleeving with the tube main body 11 is preferably equal to or slightly smaller than the inner diameter of the tube main body 11. The flexible cap 12 may also be attached to the inside of the rear end of the tube body 11 by means of glue or a hot-melt connection or the like. After the water bag 3 is placed in the flexible cap 12, the flexible cap 12 is attached to the tube body 11.

The maximum dimension of the interior of the flexible cap 12 is preferably, but not limited to, greater than the dimension at the outlet of the flexible cap 12, e.g., the surface of the flexible cap 12 is substantially spherical. Accordingly, the size of the water bag 3 is larger than that of the outlet of the flexible cap 12 when the water bag 3 is not broken, i.e., the outlet of the flexible cap 12 and the end of the tube body 11 form a step surface which forms a limit to the water bag 3 to confine the water bag 3 in the flexible cap 12. Of course, the shape of the flexible cap 12 is not limited to the above, and as shown in fig. 3, the flexible cap 12 may include a cylindrical section and a circular truncated cone section, and the circular truncated cone section forms a step surface 13 for limiting the water bag 3. The water bag 3 may be placed directly inside the flexible cap 12. Of course, the water bag 3 may be fixed therein by means of an adhesive in order to make the position thereof more stable.

For convenience of operation, as shown in fig. 1, a handle 4 for a user to hold may be provided on the outer circumference of the tube assembly 1. Specifically, the handle 4 is provided on the outer periphery of the tube main body 11. The handle 4 may be made of, but is not limited to, rubber or plastic material. The handle 4 may be provided with, but is not limited to, a depression 41 for receiving the user's finger for easy handling by the user.

Briefly describing the using process of the stick for collecting the evidence provided by the present embodiment, the operator manually presses the rear end of the tube assembly 1, for example, presses the flexible cap 12 at the rear end of the tube assembly 1, so as to break the water bag 3 in the flexible cap 12, and then the operator lightly throws the stick, so as to make the water in the water bag 3 flow from the rear end of the tube assembly 1 to the front end of the tube assembly 1 to wet the cotton thread head 2. After the wetting is finished, the evidential substance can be stained.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
