[0020] In this embodiment, the outer shell 1 includes a driving motor 11, a signal receiver 14 and a receiving antenna 143. The outer shell 1 is incompletely circular, and the receiving antenna 143 can receive an unlocking or locking signal. When the receiving antenna 143 receives the signal, it transmits it to the signal receiver 14, and the signal receiver 14 transmits the signal to the driving motor 11, so that the driving motor 11 is started. The driving motor 11 is fixedly connected to the inner wall of one side of the outer shell 1. The driving motor 11 is located on the inner side of the outer shell 1, and the driving motor 11 corresponds to the center of the outer shell 1. A connecting shaft 12 is provided on one side of the outer shell 1. When the driving motor 11 receives the signal transmitted by the signal receiver 14, it will drive the connecting shaft 12 to rotate clockwise or counterclockwise. The needle rotates, a turntable 13 is provided on the side of the connecting shaft 12 away from the driving motor 11, and the turntable 13 is fixedly connected to the connecting shaft 12. When the connecting shaft 12 rotates, the turntable 13 will also rotate synchronously. A connecting rod 131 is provided on one side of the turntable 13, and one end of the connecting rod 131 is fixedly connected to the turntable 13. When the turntable 13 rotates, the connecting rod 131 will rotate around the center of the circle of the outer shell 1. A limiting rod 2 is provided on the end of the connecting rod 131 away from the turntable 13, and the end of the connecting rod 131 away from the turntable 13 is fixedly connected to the limiting rod 2. When the connecting rod 131 rotates inside the outer shell 1, the limiting rod 2 will also rotate inside the outer shell 1. When the limiting rod 2 is located inside the outer shell 1, the remote control lock is in an unlocked state, and the limiting rod 2 is rotated counterclockwise. When it is rotated to the outside of the outer shell 1 and both ends are located inside the outer shell 1, the remote control lock will be in a locked state, so that the device can be locked. When it is necessary to unlock, the limit rod 2 can be rotated clockwise to the inside of the outer shell 1 to keep the remote control lock unlocked. The signal receiver 14 is fixedly connected to the top of the connecting shaft 12. The signal receiver 14 is located between the driving motor 11 and the turntable 13. The receiving antenna 143 is movably connected to one side of the signal receiver 14, and the receiving antenna 143 is connected to the signal receiver 14 through a spring 142. The spring 142 is located at the bottom of the receiving antenna 143. The spring 142 can apply a downward pulling force to the receiving antenna 143. The receiving antenna 143 is located above the turntable 13 and the connecting shaft 12. The bottom of the receiving antenna 143 is in contact with the top of the turntable 13. The turntable 13 is elliptical in shape. The connecting rod 131 is connected to the short axis side of the turntable 13. Therefore, when the limit rod 2 rotates to unlock or lock, the turntable 13 will rotate 180 degrees. Therefore, the bottom of the receiving antenna 143 will first contact the long axis side of the turntable 13. Then, when the turntable 13 rotates 90 degrees, the bottom space of the receiving antenna 143 expands. With the tension of the spring 142, the receiving antenna 143 moves downward to the inside of the outer shell 1. When the turntable 13 continues to rotate 90 degrees, the turntable 13 will push the receiving antenna 143 upward. Therefore, in the process of unlocking and locking, the receiving antenna 143 will first retract into the inside of the outer shell 1, and then move upward to reset.The contact between the receiving antenna 143 and the outer shell 1 during movement can achieve the purpose of scraping off the dust on the surface of the receiving antenna 143, so that the surface of the receiving antenna 143 can be cleaned during the process of unlocking and locking, which is conducive to reducing dust accumulation and avoiding the situation where excessive dust accumulation causes signal loss and reduced receiving sensitivity.

[0021] The limit rod 2 is arc-shaped, and the shape of the limit rod 2 matches that of the outer shell 1; the center of the limit rod 2 corresponds to the center of the outer shell 1. When the limit rod 2 is rotated to the outside of the outer shell 1, both ends of the limit rod 2 are located inside the outer shell 1, and the device can be locked.

[0022] Two through slots 15 are formed on the outer shell 1 , and the limiting rod 2 is movably connected to the inner side of the through slots 15 ; the sizes of the through slots 15 and the limiting rod 2 match, and the two through slots 15 are symmetrical to each other.

[0023] A through hole 16 is provided at the top of the outer shell 1, and the receiving antenna 143 is movably connected to the inner side of the through hole 16; the through hole 16 matches the size of the receiving antenna 143, so when the receiving antenna 143 moves up and down, dust on the surface of the receiving antenna 143 can be scraped off.

[0024] A plurality of torsion spring connection seats 17 are provided on the top of the outer shell 1, and a scraper 18 is rotatably connected to one side of the torsion spring connection seat 17, and a plurality of scrapers 18 are distributed on the outside of the through hole 16; when the receiving antenna 143 moves downward, the scraper 18 will always be in contact with the outside of the receiving antenna 143, thereby achieving the purpose of scraping off the dust on the outside of the receiving antenna 143.

[0025] A connection slot 141 is provided on one side of the signal receiver 14, and the receiving antenna 143 is slidably connected to the inner side of the connection slot 141; the receiving antenna 143 is limited by the signal receiver connection slot 141, so that the receiving antenna 143 can only move in a straight line.

[0026] The working principle and use process of the utility model are as follows: when the limit rod 2 is located inside the outer shell 1, the remote control lock is in an unlocked state, and an unlock or lock signal can be received through the receiving antenna 143. When the receiving antenna 143 receives the lock signal, it is transmitted to the signal receiver 14, and the signal is transmitted to the drive motor 11 through the signal receiver 14. When the drive motor 11 receives the signal transmitted by the signal receiver 14, it drives the connecting shaft 12 to rotate the connecting shaft 12 counterclockwise. By rotating the limit rod 2 counterclockwise to the outside of the outer shell 1 and both ends are located inside the outer shell 1, the remote control lock will be in a locked state, thereby locking the device. When it is necessary to unlock, an unlock signal is sent to the receiving antenna 143, causing the limit rod 2 to rotate clockwise to the inside of the outer shell 1 , the remote control lock can be kept in the unlocked state. At the same time, when the limit rod 2 rotates to unlock or lock, the turntable 13 will rotate one hundred and eighty degrees. Therefore, the bottom of the receiving antenna 143 will first contact the long axis side of the turntable 13, and then when the turntable 13 rotates ninety degrees, the bottom space of the receiving antenna 143 expands. With the tension of the spring 142, the receiving antenna 143 moves downward to the inside of the outer shell 1. When the turntable 13 continues to rotate ninety degrees, the turntable 13 will lift the receiving antenna 143 upward. Therefore, in the process of unlocking and locking, the receiving antenna 143 will first retract into the inside of the outer shell 1, and then move upward to reset. Through the contact between the receiving antenna 143 and the outer shell 1 during movement, the dust on the surface of the receiving antenna 143 can be scraped off.
