A special-shaped groove A 12 matching with the special-shaped block A 10 is opened on the bottom wall of the screw head 7. After the stud 6 is inserted into the through hole 4, the stud 6 is screwed into the screw hole 3 through the special-shaped block A 10 and the mounting post 9. After the stud 6 is screwed into the screw hole 3, the screw head 7 is located inside the countersunk hole 5. A plug hole 13 communicating with the countersunk hole 5 is opened on the bottom wall of the base 2. The diameter of the plug hole 13 is larger than that of the countersunk hole 5. Threads are provided on the outer side of the plug 8 and the inner side of the plug hole 13. A special-shaped groove B 14 matching with the special-shaped block B 11 is opened on the bottom wall of the plug 8. The plug 8 is screwed into the plug hole 13 through the special-shaped block B 11 and the mounting post 9 and abuts against the screw head 7. When the utility model is used, the housing 1 and the base 2 are sleeved on the steering shaft of the steering wheel to align the screw hole 3 with the through hole 4. The stud 6 is inserted into the through hole 4, and then the special-shaped block A 10 is inserted into the special-shaped groove A 12 to abut against the screw head 7. The mounting post 9 is rotated to screw the stud 6 into the screw hole 3. After the stud 6 is locked, the housing 1 and the base 2 will be clamped on the steering shaft of the steering wheel to complete the installation of the housing 1 and the base 2. The special-shaped block B 11 is inserted into the special-shaped groove B 14 to abut against the plug 8. The mounting post 9 is rotated to screw the plug 8 into the plug hole 13 to abut against the screw head 7. Since the screw head 7 is located inside the countersunk hole 5 after the stud 6 is screwed into the screw hole 3 and the diameter of the plug hole 13 is larger than that of the countersunk hole 5, the plug 8 will block the screw head 7. To take out the screw head 7, the plug 8 needs to be taken out first. Since specific special-shaped blocks are required to take out both the screw head 7 and the plug 8, the safety is improved. When the screw head 7 is located inside the countersunk hole 5, the annular groove 17 coincides with the jack 16. The insertion rod 15 is inserted into the jack 16 and the annular groove 17 so that the insertion rod 15 is in contact connection with the base 2 and the screw head 7. The insertion rod 15 will lock the screw head 7. To take out the screw head 7, the insertion rod 15 needs to be taken out first. The elastic sleeve 22 is sleeved on the outer side of the base 2 so that the insertion rod 15 is blocked by the elastic sleeve 22, which further improves the safety. In summary, the utility model has the beneficial effect of improving the installability, and solves the problems that the housing 1 and the base 2 of the existing electronic steering column lock are generally fixedly installed on the steering shaft of the steering wheel by screws and can be easily disassembled with some common tools, resulting in low safety and inability to prevent theft well.

Since the upper and lower ends of the spring washer 19 are respectively in contact connection with the pressing pad 18 and the screw head 7, after the stud 6 is locked, the pressing pad 18 and the spring washer 19 will be pressed by the screw head 7 inside the counterbore 5, and the spring washer 19 will apply an elastic force to the screw head 7, making the thread of the stud 6 abut against the thread of the screw hole 3, playing a role in preventing the stud 6 from loosening.
[0022] Preferably, the thread of the stud 6 is a right-hand thread, and the thread of the plug 8 is a left-hand thread. When the vehicle is running, it often experiences bumps and vibrations. Since the thread of the stud 6 is a right-hand thread and the thread of the plug 8 is a left-hand thread, it plays a further role in preventing the stud 6 from loosening.
[0023] Preferably, a magnet 20 is fixedly arranged on the front side of the plug rod 15, and a magnetic plate 21 is fixedly arranged on the side wall of the mounting post 9. Since the magnet 20 is fixedly arranged on the front side of the plug rod 15 and the magnetic plate 21 is fixedly arranged on the side wall of the mounting post 9, when taking out the plug rod 15, the magnetic plate 21 is used to suck the magnet 20, and then the plug rod 15 can be pulled out of the jack 16, playing a role in facilitating the taking out of the plug rod 15.
[0024] Preferably, an elastic sleeve 22 is sleeved on the outer side of the base 2. Since the elastic sleeve 22 is sleeved on the outer side of the base 2, it plays a role in shielding the plug rod 15.
[0025] Preferably, an elastic pad 23 is fixedly arranged on the upper side of the base 2. Since the elastic pad 23 is fixedly arranged on the upper side of the base 2, when the base 2 is installed on the steering shaft of the steering wheel, the elastic pad 23 will closely adhere to the steering shaft of the steering wheel, playing a role in preventing loosening.
[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
