[0021] 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.

[0022] The adjustable evidence re-photographing station provides two technical solutions:

[0023] like Figure 1-3The first embodiment is shown: it includes a support platform 1 and two left and right fill lights 2, a slide bar 3 is fixedly connected to the rear of the top of the support platform 1, a lifting assembly 4 is arranged on the slide bar 3, a camera fixing frame 5 which can be extended and retracted forward and backward is fixedly connected to the lifting assembly 4, an adjustable magnification mechanism 6 is arranged below the camera fixing frame 5, a support switch assembly 7 is arranged at the middle part of the top of the support platform 1, the adjustable magnification mechanism 6 includes a fixed plate 61, the top of the fixed plate 61 is fixedly connected to the camera fixing frame 5 through a T-shaped connecting rod, the top of the fixed plate 61 is rotatably connected to a rotating rod 62, the rotating rod 62 penetrates the fixed plate 61 and extends to the bottom of the fixed plate 61, one end of the rotating rod 62 located on the fixed plate 61 is fixedly connected to a disk 64, a plurality of mounting circular grooves 65 are arranged at equal distances inside the disk 64, and a plurality of mounting circular grooves 65 are inlaid with a plurality of magnification mechanisms with different magnifications. The magnifying glass 66 is provided, and a mounting circular groove 65 is reserved for not installing the magnifying glass 66 inside. One end of the rotating rod 62 located below the fixed plate 61 is fixedly connected to the driven gear 63. The bottom of the fixed plate 61 is rotatably connected to the Z-shaped rod 67. The surface of the Z-shaped rod 67 is fixedly connected to the driving gear 68. The driving gear 68 is meshed with the driven gear 63 for transmission. The right side of the bottom of the fixed plate 61 is fixedly connected to the slide block 69. The inner surface of the slide block 69 is slidably connected to the limit rod 610. The limit rod 610 penetrates the slide block 69 and extends to the outside of the slide block 69, and the head of the limit rod 610 is in the gap between the teeth of the driven gear 63. The surface of the limit rod 610 located inside the slide block 69 is sleeved with a limit spring 611. One end of the limit spring 611 is fixedly connected to the left side of the inner wall of the slide block 69, and the other end of the limit spring 611 is fixedly connected to the head of the limit rod 610.

[0024] When different magnifications of physical evidence are required, the Z-shaped rod 67 is rotated and the disk 64 is rotated through transmission, thereby changing the position of the magnifying glass 66 on the disk, so that different magnifications can be performed, thereby improving the practicality of the device when in use. At the same time, the position of the disk after rotation is positioned through the action of components such as the limit rod and the limit spring to ensure the stability of the disk position.

[0025] like Figure 1 and 4The second embodiment is shown, and the main difference from the first embodiment is that the support switch assembly 7 includes four grooves 71 opened at the bottom of the inner wall of the support platform 1, and the inner surfaces of the four grooves 71 are slidably connected with T-shaped slide bars 72, which penetrate the support platform 1 and extend to the top of the support platform 1, and a reset spring 73 is fixedly connected between the bottom of the inner wall of the groove 71 and the side opposite to the T-shaped slide bar 72, and the top ends of the four T-shaped slide bars 72 are fixedly connected with an evidence table 76, and the middle part of the bottom of the evidence table 76 is fixedly connected with a top block 74, and a contact switch 75 is embedded in the middle part of the bottom of the inner wall of the support platform 1, and the contact switch 75 is used to control the fill light 2 to turn on.

[0026] When the evidence is placed on the evidence table 76, the evidence table 76 moves downward due to the gravity of the evidence, thereby triggering the contact switch 75 to turn on the fill light 2, without manual operation, thereby improving the convenience of using the device.

[0027] When in use, the evidence is placed on the evidence table 76. Under the action of the gravity of the evidence, the evidence table 76 moves downward, and the top block 74 contacts the contact switch 75, so that the two fill lights 2 are turned on at the same time, and the camera is fixed on the camera fixing frame 5. If the magnification is insufficient during shooting, the Z-shaped rod 67 is rotated to rotate the driving gear 68, and the driving gear 68 rotates and drives the driven gear 63 to rotate. The driven gear 63 rotates and drives the disk 64 to rotate through the rotating rod 62, and the disk 64 rotates. 4 rotates and changes the position of the magnifying glass 66, so that the magnifying glass 66 with a suitable magnification enters directly below the camera. When the driven gear 63 rotates, the gear teeth of the driven gear 63 contact the limiting rod 610, and the limiting rod 610 retracts into the slide block 69, then the limiting spring 611 is stretched, and after the rotation stops, the limiting rod 610 reenters the gear teeth gap of the driven gear 63 under the reaction force of the limiting spring 611, thereby limiting the position of the disc 64 after it stops.
