[0024] like Figure 1-6As shown, a metal detector has an arbitrary telescopic structure for detecting a rod, comprising a connecting rod 1, a first sleeve 2 being slidably sleeved on the connecting rod 1, the first sleeve 2 being pulled to a suitable position, a second sleeve 3 being slidably sleeved on the first sleeve 2, a third sleeve 4 being slidably sleeved on the second sleeve 3, a first externally threaded ring 5 being fixedly sleeved on the first sleeve 2, a first connecting ring 6 being threadedly sleeved on the first externally threaded ring 5, the first connecting ring 6 being rotated and gradually moved downward by cooperating with the first externally threaded ring 5, a plurality of first connecting pieces 7 arranged circumferentially are fixedly connected to the bottom of the first sleeve 2, the first A first metal sheet 8 is fixedly connected to the connecting piece 7. As the first connecting ring 6 continuously moves downward during rotation, the first connecting ring 6 will contact multiple first metal sheets 8 and apply force to them. The force applied to the first metal sheet 8 will be transmitted to the first connecting piece 7, causing the first connecting piece 7 to deform, so that multiple first connecting pieces 7 conflict with the outer surface of the connecting rod 1, thereby fixing the position of the first sleeve 2. A second externally threaded ring 9 is fixedly sleeved on the second sleeve 3. When the second sleeve 3 is pulled to a suitable position, a second connecting ring 10 is threadedly sleeved on the second externally threaded ring 9. The second connecting ring 10 is rotated to move the second connecting ring 10 downward. A plurality of second connecting pieces 11 arranged in a circumference are fixedly connected to the bottom of the second sleeve 3. A second metal piece 12 is fixedly connected to the second connecting piece 11. When the second connecting ring 10 moves downward, it will contact the plurality of second metal pieces 12, and a force is applied to the second metal piece 12 to deform the second connecting piece 11. The plurality of second connecting pieces 11 will conflict with the outer surface of the first sleeve 2, fixing the position of the second sleeve 3. A third external threaded ring 13 is fixedly sleeved on the third sleeve 4, and the third sleeve 4 is pulled When the third sleeve 4 is in the proper position, a third connecting ring 14 is threadedly sleeved on the third external threaded ring 13. The third connecting ring 14 is rotated to move the third connecting ring 14 downward. A plurality of third connecting pieces 15 arranged in a circle are fixedly connected to the bottom of the third sleeve 4. A third metal piece 16 is fixedly connected to the third connecting piece 15. When the third connecting ring 14 moves downward, it will contact with the plurality of third metal pieces 16 and exert force on the third metal piece 16 to deform the third connecting piece 15. The plurality of third connecting pieces 15 will conflict with the outer surface of the second sleeve 3 to fix the position of the third sleeve 4.

[0025] like Figure 4 、 Figure 5 and Figure 6 As shown, the first connecting piece 7, the second connecting piece 11 and the third connecting piece 15 are all plastic connecting pieces.

[0026] When the first metal sheet 8 is subjected to a force, the first connecting sheet 7 will be deformed. When the second metal sheet 12 is subjected to a force, the second connecting sheet 11 will be deformed. When the third metal sheet 16 is subjected to a force, the third connecting sheet 15 will be deformed.

[0027] like Figure 2 and Figure 4 As shown, the first connecting piece 7 is located between the outer wall of the connecting rod 1 and the inner wall of the first external threaded ring 5 .

[0028] When the first connecting piece 7 is deformed, it will come into contact with the outer surface of the connecting rod 1 , thereby fixing the position of the first sleeve 2 .

[0029] like Figure 2 and Figure 5 As shown, the second connecting piece 11 is located between the outer wall of the first sleeve 2 and the inner wall of the second external threaded ring 9 .

[0030] When the second connecting piece 11 is deformed, it will come into contact with the outer surface of the first sleeve 2 , thereby fixing the position of the second sleeve 3 .

[0034] The metal is detected by the detection ring 18 .

[0035] Working principle: After the staff pulls the first sleeve 2 to the appropriate position, the first connecting ring 6 is rotated to gradually move downward by cooperating with the first externally threaded ring 5. As the first connecting ring 6 continues to move downward during rotation, the first connecting ring 6 will contact with multiple first metal sheets 8 and apply force to them. The force applied to the first metal sheet 8 will be transmitted to the first connecting piece 7, causing the first connecting piece 7 to deform, so that multiple first connecting pieces 7 conflict with the outer surface of the connecting rod 1, thereby fixing the position of the first sleeve 2. Similarly, after the second sleeve 3 is pulled to the appropriate position, the second connecting ring 10 is rotated to move the second connecting ring 10 downward. When the second connecting ring 10 moves downward, it will contact multiple second metal sheets The second metal sheet 12 contacts the first metal sheet 12, and a force is applied to the second connecting piece 11 to deform. The multiple second connecting pieces 11 will conflict with the outer surface of the first sleeve 2, and the position of the second sleeve 3 is fixed. After the third sleeve 4 is pulled to a suitable position, the third connecting ring 14 is rotated to move the third connecting ring 14 downward. When the third connecting ring 14 moves downward, it will contact multiple third metal sheets 16, and a force is applied to the third metal sheet 16 to deform the third connecting piece 15. Multiple third connecting pieces 15 will conflict with the outer surface of the second sleeve 3, and the position of the third sleeve 4 is fixed. It can realize multi-level telescopic adjustment according to actual needs, which is convenient for the actual use of the subsequent metal detector and has higher practicality.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
