[0056] The telescopic member 6 includes a variable diameter shaft 601, a friction block 602 and an anti-slip ring 605.

There is a limit plate 6012 at each end of the special-shaped hollow shaft 6011. The hollow connecting column 6013 is arranged on one of the limit plates 6012. The special-shaped hollow shaft 6011, the two limit plates 6012 and the hollow connecting column 6013 are integrally formed, and two friction blocks 602 are matched on the special-shaped hollow shaft 6011; the telescopic member 6 is combined with the outer tube 603 and the inner tube 604 to form a telescopic structure; the hollow connecting column 6013 of the variable diameter shaft 601 extends from one end of the inner tube 604 into the inner tube and the inner tube It is fixedly connected and limited by a limit plate 6012 connected to a hollow connecting column 6013.

The inner tube 604, the variable diameter shaft 601 and the friction block 602 are slidably arranged inside the outer tube 603. The other end of the inner tube 604 extends out of the outer tube 603. The anti-slip ring 605 is fixed at one end of the outer tube 603 away from the variable diameter shaft 601. The minimum inner diameter of the anti-slip ring 605 is smaller than the maximum outer diameter of the variable diameter shaft 601 to prevent the inner tube from slipping out during the telescopic process.

The signal switching circuit is used to switch the signal source of the transmitting antenna. When the signal source is switched to the power amplifier circuit, the transmitting antenna is driven by the internally generated signal (i.e., the waveform generated by the amplified signal generating circuit); when the signal source is switched to the outside, the transmitting antenna is connected to the external interface of the interface circuit through the signal switching circuit, and the transmitting antenna is directly driven by the external signal. This function can be used to expand the types of coding signals or assist other devices in coding operations when the coding rod is out of power. The coding unit also includes a display module, which is connected to the control circuit and is used to display information such as working status.

[0061] 2. The control circuit starts to work, and the control signal generating circuit generates a locomotive signal waveform;

[0062] 3. The waveform is amplified by the power amplifier circuit and sent to the transmitting antenna, which converts the signal into a changing magnetic field;

[0063] 4. The changing magnetic field is received by the locomotive signal receiving coil, converted into a voltage signal through the principle of magnetoelectric induction, and sent to the locomotive signal host for decoding;

[0064] 5. The operator determines whether the locomotive signal equipment is working properly by observing whether the indicator lights of the locomotive signal on-board equipment light up in the predetermined sequence.

[0065] like Fig. 20 The working process of remote control code sending with wireless module is shown as follows:

[0066] 1. With wireless module, connect to mobile phone or code-generating remote control through the wireless module;

[0067] 2. Send instructions via mobile phone or code-generating remote control;

[0068] 3. The control circuit receives the instruction and controls the signal generating circuit to generate the required waveform;

[0069] 4. The control circuit replies with a successful code sending command through the wireless module box mobile phone or the code sending remote control;

[0070] 5. The waveform is amplified by the power amplifier circuit and sent to the transmitting antenna, which converts the signal into a changing magnetic field;

[0071] 6. The changing magnetic field is received by the locomotive signal receiving coil, converted into a voltage signal through the principle of magnetoelectric induction, and sent to the locomotive signal host for decoding;

[0072] 7. The operator determines whether the locomotive signal equipment is working properly by observing whether the indicator light of the locomotive signal on-board equipment is consistent with the mobile phone or the coding remote control.

[0073] like Fig.21 As shown, when the code sending unit in the code sending rod is insufficient to meet the code sending demand or the code sending unit is insufficiently powered, the normal operation of the code sending rod can be achieved by starting the signal switching circuit. The specific code sending operation process through wired connection is as follows:

[0074] 1. The code sending rod is turned off, the signal switching circuit is powered off, and the signal source is switched to the external port;

[0075] 2. Use the signal input cable to connect the external code sending device (such as code sending device, code sending remote control, etc.) to the code sending rod;

[0076] 3. Control the external coding device to send signals. The signals drive the transmitting antenna through the signal switching circuit and convert the signals into changing magnetic fields.

[0077] 4. The changing magnetic field is received by the locomotive signal receiving coil, converted into a voltage signal through the principle of magnetoelectric induction, and sent to the locomotive signal host for decoding;

[0078] 5. The operator determines whether the locomotive signal equipment is working properly by observing whether the indicator light of the locomotive signal on-board equipment is consistent with the signal sent by the coding equipment.
