[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 2 The utility model provides a hair collection tool, including a handle 1, a movable plate 7 is fixed to the left end of the handle 1, a connecting plate 2 is connected to the left end of the movable plate 7, and a contact piece 3 is fixed to the left end of the connecting plate 2.
[0024] The connecting plate 2 and the contact piece 3 are inclined at 30 degrees, which is convenient for contacting the scalp of the person. One side of the contact piece 3 is a cutting edge, and the two groups of contact pieces 3 have one side of the cutting edge corresponding to each other, and are hinged at the leftmost end of the two groups of grips 1, that is, the leftmost ends of the two groups of grips 1 can be connected by a rotating shaft 6 to complete the relevant functions of the grips 1, and the hair can be cut by the cutting edge side of the two groups of contact pieces 3. At the same time, in the utility model, the rotating shaft 6 that completes the mutual connection function of the two groups of grips 1 can also be set at the position of the two groups of connecting plates 2, that is, the two groups of connecting plates 2 are hinged by the rotating shaft 6, which increases the length of one side of the grip 1. In actual operation, the grip 1 only needs to be slightly opened, and the opening between the two groups of contact pieces 3 can be large enough, which is convenient for operators with smaller hands to use.
[0025] In order to make the product of this technology easy to carry, the movable plate 7 and the connecting plate 2 are set in a length-adjustable mode, such as Figure 2-Figure 3 As shown, the connection plate 2 is provided with a cavity having the same shape as the movable plate 7, and the right end of the cavity is open, so that the movable plate 7 can be inserted into the cavity. When storing, the movable plate 7 is fully inserted into the connection plate 2. At this time, the shape of the hair collection tool of the utility model is in a minimum structural state, which is convenient for carrying or for users with small hands to use. When using, the movable plate 7 can be adjusted according to the user's own situation, so that it can be used by users with different hand shapes (female collectors with small hands generally like to adjust this product to a small size state for easy gripping and exerting force, while male collectors with large hands generally like to adjust this product to a large size device).
[0026] A limiting mechanism is provided on the movable plate 7 to facilitate fixation after the size adjustment is completed. The limiting mechanism includes a fixed block 13 installed on the upper surface of the front end of the movable plate 7. Relative to the position of the fixed block 13, a longitudinal long hole 14 is opened in the cavity along the longitudinal direction of the connecting plate 2, and the long hole 14 penetrates the outer wall of the connecting plate 2. The size of the long hole 14 is slightly larger than the fixed block 13, so that the fixed block 13 can move along the long hole 14. A telescopic rod 10 is fixed on one side of the fixed block 13, and a clamping block 9 is fixed on the other end of the telescopic rod 10. In addition, a reset spring 8 is set on the telescopic rod 10, and one end of the reset spring 8 abuts against the fixed block 13, and the other end abuts against the clamping block 9 to achieve rapid reset of the telescopic rod 10. Relative to the clamping block 9, a number of transversely arranged card slots 11 are provided on the long hole 14. The number of the card slots 11 depends on the size of the relevant product. If the size is large, multiple card slots 11 can be provided, and if the size is small, a small number of card slots 11 can be provided. The telescopic rod 10 provides a lateral rigid connection on one hand, and on the other hand, under the action of the return spring 8, the position of the clamping block 9 is adjusted to complete the position adjustment work between the moving plate 7 and the connecting plate 2.
[0027] The upper surface of one of the two groups of contact sheets 3 of the device is provided with a measuring platform 4 (the other group does not need to be provided with a measuring platform 4), the height of the measuring platform 4 is fixed at 3 cm, and a 3 cm scale can be set to facilitate the comparison of hair length to comply with relevant rules and regulations for hair extraction. The upper surface of the measuring platform 4 is provided with a sticker positioning plate 5, and the upper surface of the sticker positioning plate 5 is provided with multiple layers of stickers 12, and the positioning plate 5 can prevent the stickers 12 from being offset when pasted.
[0028] Working principle: When sampling the hair of drug-related personnel, first adjust the movable plate 7 and the connecting plate 2 to the size that meets the operating habits;
[0029] Secondly, open the two groups of contact pieces 3, and the distance between the blade tips of the two groups of contact pieces 3 is at least 10 cm. At this time, the staff member presses the movable plate 7 and the connecting plate 2 where the contact pieces 3 on one side of the measuring table 4 are located with the thumb of the right hand, and holds it with the tiger's mouth, holds the hair to be extracted with the left hand, and measures the specific size through the measuring table, and then sticks it on the top sticker 12; at this time, the reason why the right hand does not hold the handle 1 is that it often happens that before the measurement of the hair to be extracted is completed, the right hand is habitually closed, on the one hand, it will cause unqualified hair sampling, on the other hand, it is easy to hurt the left hand, or when multiple people collaborate, it is easy to hurt other people; and because the shape of the handle 1 is ergonomic (normal scissors shape), its shape is large, if the movable plate 7 and the connecting plate 2 are not adjusted to the maximum position, it is easy to cause the female worker with small hands to be unable to fix the hair sampling device, therefore, another important function of the size adjustment device provided here on the basis of portable size adjustment is to facilitate operation and standardization;
[0030] Finally, pinch the movable plate 7 and the connecting plate 2 with the index finger and thumb of the left hand, and operate the handle 1 with the right hand to cut the relevant hair, then tear off the sticker 12 with the hair, and then stick the collected hair on the torn sticker 12 on aluminum foil, mark the root end of the hair, package it and put it into the evidence bag with the collection record filled in, and the sampling is completed.
[0031] If the amount collected the first time is not enough, you can follow the above steps to start the second collection. When collecting, fix the hair with the second layer of sticker 12 from the top and then cut the hair. And so on for subsequent collections until the amount is met. Finally, send the sample to the laboratory for inspection. Since there is no sticker 12 at the end that is the root of the hair, it is easy for the inspector to identify it, which is convenient for subsequent inspections.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
