Description
Technical Field
The utility model relates to the technical field of sticking and taking devices, in particular to a material evidence sticking and taking device.
Background
In order to be able to more quickly break criminal cases, forensics often need to extract human cells, which may be shed from criminal suspects, from the body of a material evidence or victim left over at the criminal scene for criminal technical analysis when criminal investigation is performed on the criminal scene. In the past, the extraction method of the material evidence comprises the steps of soaking a cotton swab in deionized water, wiping back and forth at a part possibly left by the material evidence, and then placing the cotton swab with the attached exfoliated cells in a test tube or a material evidence bag for storage. However, in some corners, it is inconvenient to take a material evidence, such as an elongated hole in the external environment, which causes difficulty in evidence collection for workers, and the convenience of the adhesive device is not high, so that it is necessary to provide a material evidence adhesive device.
Disclosure of Invention
In order to achieve the above purpose, the present utility model adopts the following technical scheme: a physical evidence sticking device, comprising: the crescent telescopic link, a plurality of circular notches have been seted up to crescent telescopic link's one end, a plurality of circular notch's inner wall fixedly connected with a plurality of first springs, a plurality of first top fixedly connected with spheroid of spring, a plurality of spherical notches have been seted up to crescent telescopic link's one end, spherical notch's inner wall joint is in spheroidal one side, be equipped with rotatory joint mechanism on the crescent telescopic link, crescent telescopic link's bottom fixedly connected with fixed column, the one end fixedly connected with of fixed column glues the layer of getting.
As a preferred embodiment, the bottom end of the fixing column is fixedly connected with a hemisphere.
The technical effect of adopting the further scheme is as follows: when the staff needs to get evidence and runs into the dead angle, the crescent telescopic link length is prolonged earlier, then in order to prevent that crescent telescopic link from contacting dead angle one side and taking place the automatic shortening, increase the degree of difficulty that the staff obtained evidence, so through the spheroid automatic joint of crescent telescopic link one end go up the spherical notch inner wall of one section crescent telescopic link one end can, avoid crescent telescopic link automatic shortening's problem, when the staff needs to shorten crescent telescopic link, only need manual extrusion spheroid alright can shorten crescent telescopic link, in order to prevent to glue and get the layer and contact the unsmooth one side in dead angle when rotatory operation, can be scraped the evidence, so draw out the unsmooth top in dead angle one side through the hemisphere, improve the efficiency of collecting evidence, at last when need rotatory the sticking layer, only need through rotatory joint mechanism can.
To explain, because the expansion link is used the time limit overlength probably when the one section on rotatory expansion link top, can take place other sections because of frictional force is too low unable rotation, so design the expansion link into crescent moon shape, the expansion link is whole rotatory simultaneously of being convenient for, avoids unable rotatory problem to take place.
As a preferred implementation mode, the rotary clamping mechanism comprises a circular plate, the top fixedly connected with circular plate of crescent telescopic link, the top rotation of crescent telescopic link is connected with solid fixed ring, gu fixed ring's inner wall rotates to be connected in one side of circular plate, gu fixed ring's one side fixedly connected with fixed section of thick bamboo, the screw thread groove has been seted up to the inner wall of fixed section of thick bamboo, the one end rotation of screw thread groove is connected with the threaded rod, the one end fixedly connected with semicircular baffle of screw thread groove.
The technical effect of adopting the further scheme is as follows: when the staff needs rotatory crescent telescopic link, only need manual round trip rotation threaded rod can, in order to prevent when the rotatory threaded rod of one hand, can't keep crescent telescopic link original position, so the other hand of staff holds solid fixed ring, it is rotatory to drive the circular plate when crescent telescopic link is rotatory, gu fixed ring can restrict the circular plate that is rotating on the other hand of staff, in order to prevent to get evidence and end the back, the threaded rod is carrying in and is easy free rotation, this can cause glueing the layer and throw away the material evidence of being stained with, so can't continue the same direction rotation through the semicircular baffle on screw groove top messenger threaded rod, and then lead to the threaded rod to be static state, unless reverse rotation can.
As a preferred implementation mode, one end of the crescent telescopic rod is clamped with two arc plates, one side of each arc plate is fixedly connected with a second spring, and the top end of the second spring is fixedly connected with a container barrel.
The technical effect of adopting the further scheme is as follows: after removing the material evidence, the staff shortens crescent telescopic link earlier, and then entangles the container section of thick bamboo from crescent telescopic link's bottom and glues the layer of getting, prevents that the material evidence from dropping, makes arc joint in crescent telescopic link's one end simultaneously with second spring, prevents that the container section of thick bamboo from breaking away from crescent telescopic link's bottom automatically.
As a preferred embodiment, the hemispherical body is made of rubber.
The technical effect of adopting the further scheme is as follows: under the condition of contacting with the rugged environment, the rubber has better flexibility, further reduces the abrasion of the hemispheroids and prolongs the service life of the sticking device.
Compared with the prior art, the utility model has the advantages and positive effects that,
according to the sticking and taking device, the problem that the sticking and taking device is low in convenience is solved through the rotary clamping mechanism and the crescent telescopic rod, when staff needs to collect the material evidence, the material evidence at dead angles can be collected through prolonging the proper length of the crescent telescopic rod, and then the threaded rod in the rotary clamping mechanism is used for repeatedly rotating the sticking and taking layer back and forth so as to facilitate collection of the material evidence of filiform substances, so that the sticking and taking device is simple in operation, and the convenience is improved.
