Multiple anti-interference coils 18 are sleeved on the outer surface of the reinforcement strip 4. The extension block 17 limits the anti-interference coil 18. The multiple anti-interference coils 18 can effectively reduce the susceptibility of the antenna body 13 signal to interference. The tempered sleeve 6 is threadedly connected to the outer surface of the first spiral tube 2, so that the rubber pad 7 contacts the top of the reinforcement strip 4. The top of the reinforcement strip 4 is limited by the limiting groove 8. The sealing ring 12 can increase the sealing of the connection between the tempered sleeve 6 and the base 1. The base 1 is connected to the connecting plate 20 through the stud 19, and the connecting plate 20 is hinged inside the connecting seat 21. At the same time, the connecting seat 21 is connected to the cylinder seat 23 through the universal head 22, so that the antenna can be adjusted at multiple angles when in use. The second screw tube 25 is connected to the handheld device. When the handheld device is in use, the external tempered sleeve 6 provides preliminary protection for the antenna body 13, which can reduce the impact of the external environment on the antenna body 13. Multiple reinforcement strips 4 ensure that the inner side of the tempered sleeve 6 is evenly stressed. The rubber pad 7 can buffer the force, so that the antenna body 13 is fully protected and avoids damage when the antenna falls and collides. There is a gap between adjacent reinforcement strips 4 to reduce the obstruction of the antenna body 13 signal, improve the actual signal receiving and sending effect, and have a good use effect.
