[0023] Reference Figure 3As shown, a rectangular magnet 11 is provided on one side surface of the upper shell 1 and the lower shell 2 close to the telescopic handle 6. The rectangular magnet 11 facilitates the movement of the shell 2 and the upper shell 1 under the change of magnetism.

[0024] Reference Figure 4 As shown, a rectangular protective groove 401 is opened inside the shock-absorbing protective shell 4, and neatly arranged circular through holes 402 are opened on one side of the surface of the rectangular protective groove 401. A neatly arranged shock-absorbing spring 12 is opened at the bottom of the rectangular protective groove 401, and the circuit board body 5 is located at the top of the shock-absorbing spring 12 opened in the rectangular protective groove 401. The shock-absorbing protective shell 4 and the shock-absorbing spring 12 are helpful to protect the circuit board body 5 and prevent the circuit board body 5 from being damaged by impact.

[0025] Reference Figure 5 As shown, the telescopic handle 6 is provided with a telescopic groove 601 at the position where the upper shell 1 and the lower shell 2 are movably connected, and the inner walls on the upper and lower sides of the telescopic groove 601 are provided with limiting grooves 602. The limiting grooves 602 are helpful to limit the position of the upper shell 1 and the lower shell 2 inside the telescopic handle 6.

[0026] Reference Figure 5 As shown, a power supply component 13 is fixedly connected inside the handshake column 9, and the power supply component 13 is conducive to powering the metal detector.

[0027] Reference Figure 6 As shown, an electromagnetic tube 14 is provided on one side of the power supply component 13 close to the telescopic handle 6, an electromagnetic chamber 1401 is provided inside the electromagnetic tube 14, a cylindrical rod 1402 is provided inside the electromagnetic chamber 1401, an electromagnetic sheet 1403 is fixedly connected to one end of the cylindrical rod 1402 away from the electromagnetic chamber 1401, an electromagnetic coil 15 is movably sleeved on the surface of the cylindrical rod 1402 located inside the electromagnetic chamber 1401, and the electromagnetic tube 14 and the electromagnetic coil 15 facilitate the change of the current so that the magnetism of the electromagnetic sheet 1403 changes to complete the extension and retraction.

[0028] The working principle of the utility model is as follows: first, when using it, hold the handshake column 9 and then turn on the detector, so that the upper shell 1 and the lower shell 2 inside the telescopic handle 6 are aligned with the person who needs to be detected. When it is necessary to detect the legs of the detected person, the first button 7 on the surface of the telescopic handle 6 is pressed to change the current inside the electromagnetic cavity 1401 opened by the electromagnetic tube 14 through the power supply component 13 inside the handshake column 9. At this time, the current changes the magnetism of the electromagnetic sheet 1403 through the electromagnetic coil 15 on the surface of the cylindrical rod 1402. At this time, the electromagnetic sheet 1403 repels the rectangular magnet 11 fixed at one end of the upper shell 1 and the lower shell 2, so that the upper shell 1 and the lower shell 2 move under the push of the rectangular magnet 11. At this time, the rectangular magnet 11 is restricted by the limit groove 602 opened in the telescopic groove 601 opened in the telescopic handle 6, so that the upper shell 1 and the lower shell 2 move. The shell 2 is always located inside the telescopic handle 6. At this time, the distance between the upper shell 1 and the lower shell 2 and the telescopic handle 6 increases, thereby increasing the length of the detector, preventing the need to bend or squat when detecting lower positions such as the legs, thereby reducing manual labor intensity. Then, after the detection is completed, the second button 8 is pressed to change the magnetism of the electromagnetic sheet 1403 again. At this time, the electromagnetic sheet 1403 adsorbs the rectangular magnet 11, so that the rectangular magnet 11 drives the upper shell 1 and the lower shell 2 into the telescopic groove 601 for reset. Then, in the process of holding the detector, when the detector is hit or falls, the shock-absorbing protective shell 4 in the lower shell 2 protects the circuit board body 5 to prevent the circuit board body 5 from shaking inside the groove 3 and causing bumps, and the shock-absorbing spring 12 reduces the vibration force generated by the impact, thereby ensuring the service life of the circuit board body 5.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
