At this time, the lock block is disengaged from the slot provided on the side wall of the plug to release the limit on the plug. At this time, the transmitter is pulled outward to disengage the plug from the socket, thereby realizing the separation of the transmitter and the receiver for use. After use, the transmitter can be spliced ​​to the receiver. At this time, the plugs on both sides of the inner end of the transmitter will be plugged into the sockets in the socket. The opposite ends of the latch and the lock block are designed to be inclined, so that the latch will first abut the lock block to compress the reset spring and move outward to make way, until the latch is fully inserted into the socket, the lock block will encounter the slot, and then it will be engaged in the slot under the rebound of the reset spring, thereby firmly locking the latch to achieve a firm splicing of the transmitter and the receiver into a whole for easy storage and retrieval.

The movement of the slider drives the piston cylinder at the end of the micro air pump to communicate with the detection head plugged into the end of the piston cylinder to move outward together, thereby allowing the detection head to extend a certain distance. At this time, if the distance is not enough for the detection head to extend into the detection position, the micro air pump can be started to inflate the inner cavity of the piston cylinder. After the inside of the piston cylinder is inflated, the piston in the piston cylinder will be affected by the air pressure and push the detection head to extend outward again for a certain distance. distance, so that the detection head extends to the maximum distance, so as to realize the detection of lines in narrow locations. In addition, the device has added some value-added auxiliary designs. For example, when the cable connection groove is blocked by dust and the network cable is connected, the fan can be started to generate strong airflow to blow air into the cable connection groove through the air holes to expel dust. Moreover, when detecting in the narrow space mentioned above, the dark area can be illuminated by turning on the lighting to assist the detection. At the same time, since rollers are provided on both sides of the end of the detection head, the detection head does not need to directly contact and rub against the wall during detection, so as to protect the detection head and thus increase its service life.

The plug-in of the detection head 4 The end is fixedly connected to the piston inside the piston cylinder 18, a micro air pump 19 is fixedly installed on the end of the piston cylinder 18, the inner gas end of the micro air pump 19 is connected to the inner cavity of the piston cylinder 18, the outer end of the socket 12 is provided with an air hole 20 arranged opposite to the outer gas end of the micro air pump 19, and a dustproof net is also arranged in the air hole 20, a slider 21 is slidably installed on the inner side wall of the socket 12, the slider 21 is fixedly connected to the micro air pump 19, the inner side wall of the socket 12 is provided with a transverse groove adapted to the slider 21, the slider 21 is slidably installed in the transverse groove, a screw rod 22 is threadedly connected to the slider 21, and a motor 23 whose output shaft is fixed to the end of the screw rod 22 is fixedly installed on the inner wall of the socket 12.

[0030] Through the sleeve design of the detection head 4 and the piston cylinder 18, when the device is used and a narrow situation is encountered that is inconvenient for the receiver 2 to enter for detection, the motor 23 can be started to drive the screw rod 22 to rotate, thereby causing the slider 21 to move toward the detection end of the receiver 2. The movement of the slider 21 drives the piston cylinder 18 at the end of the micro air pump 19 to communicate with the detection head 4 plugged into the end of the piston cylinder 18 to move outward together, so that the detection head 4 extends a certain distance.

[0031] The implementation principle of a multifunctional cable finder embodiment of the present application is:

[0032] First, by designing the latch 13 and the socket 12 on the transmitter 1 and the receiver 2 respectively, when the transmitter 1 and the receiver 2 need to be used separately, first pull the pull rod 17 outward to drive the lock block 15 to compress the reset spring and move outward. At this time, the lock block 15 will be disengaged from the slot 16 provided on the side wall of the latch 13 to release the limit on the latch 13. At this time, pull the transmitter 1 outward to make the latch 13 disengage from the socket 12, so that the transmitter 1 and the receiver 2 can be separated for use. After use, the transmitter 1 can be spliced ​​to the receiver 2. At this time, the latches 13 on both sides of the inner end of the transmitter 1 will be plugged into the sockets 14 in the socket 12. Since the opposite ends of the latch 13 and the locking block 15 are inclined, the latch 13 will first abut the locking block 15 to compress the reset spring and move outward to make way, until the latch 13 is fully inserted into the socket 14, the locking block 15 will encounter the card slot 16, and will be engaged into the card slot 16 under the rebound of the reset spring, thereby firmly locking the latch 13 to achieve a firm splicing of the transmitter 1 and the receiver 2 into a whole for easy storage and retrieval. After the transmitter 1 and the receiver 2 are spliced, the detection head 4 will be inserted into the storage slot 6, and the cable connection slot 7 will also be fitted and closed by the inner end of the receiver 2, thereby achieving protection for the detection head 4 and the cable connection slot 7 when idle.

[0033] Furthermore, through the sleeve design of the detection head 4 and the piston cylinder 18, when the device is used and encounters a narrow situation that is inconvenient for the receiver 2 to enter for detection, the motor 23 can be started to drive the screw rod 22 to rotate, thereby causing the slider 21 to move toward the detection end of the receiver 2. The movement of the slider 21 drives the piston cylinder 18 at the end of the micro air pump 19 to communicate with the detection head 4 plugged into the end of the piston cylinder 18 to move outward together, thereby allowing the detection head 4 to extend a certain distance. At this time, if the distance is not enough for the detection head 4 to extend into the detection position, the micro air pump 19 can be started to inflate the inner cavity of the piston cylinder 18. After the interior of the piston cylinder 18 is inflated, the piston in the piston cylinder 18 will be affected by the air pressure to push the detection head 4 It is extended outward for a certain distance again, so that the detection head 4 extends to the maximum distance, so as to realize the detection of lines in narrow positions. In addition, the device has added some value-added auxiliary designs. For example, when the cable connection groove 7 is blocked by dust and the network cable is connected, the fan 8 can be started to generate a strong airflow to blow air into the cable connection groove 7 through the air holes to expel the dust. Moreover, when detecting in the narrow space mentioned above, the dark area can be illuminated by turning on the lighting 10 to assist the detection. At the same time, since rollers are also provided on both sides of the end of the detection head 4, the detection head 4 does not need to directly contact and rub against the wall during detection, so as to protect the detection head 4 and thus increase the service life.
