DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] like Figure 1-5 As shown, a handle moving forward and backward structure of a metal detector includes a telescopic rod 1, a sleeve 2 is slidably sleeved on the telescopic rod 1, a handle 15 is fixedly installed on the sleeve 2, symmetrically distributed mounting blocks 3 are fixedly connected to the sleeve 2, a connecting shaft 4 is fixedly connected between the two mounting blocks 3, a connecting block 5 is rotatably sleeved on the connecting shaft 4, an opening 6 is opened on the sleeve 2, a stop block 7 is fixedly connected to the top of the connecting block 5, both mounting blocks 3 are fixedly connected to a fixed block 8, a guide rod 9 is slidably penetrated on the fixed block 8, a rectangular block 10 is fixedly connected to the back of the two guide rods 9, an arc block 11 is fixedly connected to the back of the rectangular block 10, a symmetrically distributed limit block 12 is fixedly connected to the bottom of the rectangular block 10, a top block 13 is connected to the front of the guide rod 9, and a spring 14 sleeved on the outside of the guide rod 9 is fixedly connected between the top block 13 and the fixed block 8.

[0022] When the operator needs to adjust the front and rear position of the handle 15, the arc block 11 is used to pull the rectangular block 10 away from the mounting block 3, and the top block 13 and the guide rod 9 follow the rectangular block 10 to move. The spring 14 is compressed and deformed under force, so that the two limit blocks 12 are out of contact with the connecting block 5, and then the connecting block 5 is rotated to disengage the block 7 from the opening 6. After the handle 15 is moved to the appropriate position, the connecting block 5 is rotated in the opposite direction to make the connecting block 5 in a horizontal state. At this time, the connecting block 5 is in contact with the mounting block 3, the block 7 is in the opening 6, and the block 7 is in contact with the outer surface of the telescopic rod 1. The arc block 11 is closed, and then the arc block 11 is released. The elastic force of the spring 14 drives the top block 13 to move away from the fixed block 8. Finally, the rectangular block 10 is fitted with the mounting block 3 through the guide rod 9, and the two limit blocks 12 are fitted with the connecting block 5. The connecting block 5 is limited by the two limit blocks 12 to prevent the connecting block 5 from rotating. The force of the block 7 on the telescopic rod 1 is used to fix the position of the sleeve 2 on the telescopic rod 1, and the position of the handle 15 is also fixed accordingly. The overall operation is simple and convenient, which is convenient for operators of different heights to hold the handle 15 after the position is adjusted, and the applicability is more extensive.

[0023] like Figure 1 As shown, a control box 16 is installed at one end of the handle 15 away from the sleeve 2 .

[0024] When the position of the handle 15 is adjusted to move forward and backward, the control box 16 moves along with the handle 15 .

[0025] like Figure 3 、 Figure 4 and Figure 5 As shown, the stop block 7 is located in the opening 6 , and the stop block 7 is in contact with the outer surface of the telescopic rod 1 .

[0026] The force exerted by the stop block 7 on the telescopic rod 1 fixes the position of the sleeve 2 on the telescopic rod 1, and the position of the handle 15 is also fixed accordingly.

[0027] like Figure 3 and Figure 5 As shown, the stopper 7 is a hard rubber block.

[0028] When the stopper 7 is in contact with the outer surface of the telescopic rod 1 , a greater friction coefficient can be created between the stopper 7 and the telescopic rod 1 , thereby ensuring a good positioning effect on the sleeve 2 and the handle 15 .

[0029] like Figure 3 As shown, the rectangular block 10 is fitted with the mounting block 3 , and the limit stopper 12 is fitted with the connecting block 5 .

[0030] The connection block 5 is limited by two limit blocks 12 to prevent the connection block 5 from rotating, so that the stop block 7 is always in contact with the telescopic rod 1.

[0031] like Figure 3 As shown, the left and right end surfaces of the connecting block 5 are tightly fitted with the two mounting blocks 3 respectively.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
