Detailed Description of the Invention

[0018] The following further describes the present application in detail Figures 1-5 with reference to the attached drawings.

[0019] The embodiment of the present application discloses a criminal investigation and positioning device, including a rod body 1, a cover body 3 and a pad 4 are provided at the lower end of the rod body 1, the cover body 3 is fixedly connected to the rod body 1, the pad 4 is detachably connected to the cover body 3 through a mounting mechanism, a groove 16 with an opening facing downward is provided in the cover body 3, a metal detector 5 is mounted in the groove 16, a telescopic spring 17 is fixedly connected in the groove 16, one end of the telescopic spring 17 is against the surface of the metal detector 5, a locator 12 is fixedly connected to the surface of the pad 4, and a signal transmitting end of the locator 12 is provided on the surface of the metal detector 5, when the pad 4 is connected to the cover body 3, the locator 12 and the metal detector 5 are both accommodated in the groove 16, and the telescopic spring 17 is in a compressed state.

[0020] Furthermore, a handle 2 is fixedly connected to the upper end of the rod body 1 .

[0021] In this embodiment, during criminal investigation and survey, first, a location can be taken as a reference point, the pad 4 and the cover 3 are disassembled, and then the pad 4 with the locator 12 is placed at the reference point. After the staff records the position of the reference point, they hold the handle 2 to drive the rod body 1 and the cover 3 to move and search the crime scene. When the metal detector 5 detects a metal weapon, the locator 12 transmitting end located on the surface of the metal detector 5 can send the signal of the metal weapon to the locator 12 body on the pad 4, and the locator 12 can receive the position of the metal weapon relative to the reference point, so that the staff does not need to measure or record again. It is quick and convenient to use, and the survey efficiency is improved.

[0022] In addition, the compressed telescopic spring 17 will be reset, thereby driving the metal detector 5 to move out of the groove 16, which can ensure that the metal detector 5 can detect normally.

[0023] It should be noted that the metal detector 5 and the locator 12 are both existing devices, and the working principles of the metal detector 5 and the locator 12 are all existing conventional technologies, which will not be repeated here.

[0024] Furthermore, positioning rods 13 are fixedly connected on both sides of the pad 4, and a socket 15 adapted to the positioning rod 13 is opened inside the cover body 3, and limiting grooves 14 are opened at both ends of the positioning rod 13. When the positioning rod 13 passes through the socket 15, the limiting grooves 14 and the pad 4 are located on both sides of the cover body 3, and the surface of the cover body 3 is connected to the limiting plate 6 by setting a moving mechanism, and the limiting plate 6 can be moved into or out of the limiting groove 14.

[0025] Further, the moving mechanism includes a rotating ring 7 sleeved on the outer surface of the rod body 1. There are two sets of limiting plates 6 which are fixedly installed on both sides of the rotating ring 7. The limiting plates 6 are L-shaped, and the ends of the limiting plates 6 far from the outer surface of the rotating ring 7 are both arc-shaped. The two sets of limiting plates 6 are centrosymmetric with the axis of the rotating ring 7 as the base point. An elastic member is arranged on the surface of the rotating ring 7, and the elastic member enables the arc-shaped part of the limiting plate 6 to pass through the limiting groove 14.

[0026] Further, the elastic member includes a fixing plate 8 fixedly installed on the outer surface of the rod body 1. A circular rod 10 is fixedly connected to the surface of the fixing plate 8. The circular rod 10 is sleeved on the outer surface of the rod body 1 and is coaxially arranged with the rod body 1. A connecting sleeve plate 9 is fixedly connected to the surface of the rotating ring 7. The connecting sleeve plate 9 is sleeved on the surface of the circular rod 10. A ring-shaped spring 11 is sleeved on the surface of the circular rod 10. One end of the ring-shaped spring 11 is fixedly connected to the fixing plate 8, and the other end of the ring-shaped spring 11 is fixedly connected to the connecting sleeve plate 9.

[0027] In this embodiment, by setting the moving mechanism and the elastic member to cooperate with each other, the cover body 3 and the cushion plate 4 can be assembled or disassembled. Specifically, when the cover body 3 and the cushion plate 4 need to be assembled, first, the user rotates the rotating ring 7 to move the arc-shaped part of the limiting plate 6 away from the jack 15. At this time, the connecting sleeve plate 9 moves along the circular rod 10, and the ring-shaped spring 11 between the connecting sleeve plate 9 and the fixing plate 8 is thus compressed. Then, the positioning rod 13 on the cushion plate 4 is passed through the jack 15, and then the rotating ring 7 is released. The compressed ring-shaped spring 11 resets, thereby driving the connecting sleeve plate 9, the rotating ring 7 and the limiting plate 6 to reset. The arc-shaped part of the limiting plate 6 thus inserts into the limiting groove 14 on the positioning rod 13, so that the positioning rod 13 can be fixed, thereby realizing the assembly of the cover body 3 and the cushion plate 4;

[0028] When the cover body 3 and the cushion plate 4 need to be disassembled, only need to rotate the rotating ring 7 to drive the limiting plate 6 to move out of the limiting groove 14. The limiting plate 6 thus no longer restricts the positioning rod 13, so that the positioning rod 13 can be moved out of the jack 15, and thus the cover body 3 and the cushion plate 4 can be disassembled.
