DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0020] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "with" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] The first aspect of the utility model is as follows Figure 4 As shown, a metal spring 116 is provided in the rocker 103 for installing and connecting the warning flag 01, and a reset spring 117 is connected between the inner side of the metal spring 116 and the inner wall of the rocker 103. Therefore, when the flagpole of the warning flag 01 is inserted into the rocker 103, the metal spring 116 exerts elastic force under the action of the reset spring 117 to squeeze and fix the flagpole of the warning flag 01, thereby ensuring that the connection has a certain stability and reducing shaking.

[0022] The metal spring piece 116 is arc-shaped, and both ends of the metal spring piece 116 are slidably connected to the inner wall of the rocker 103. Therefore, when the flagpole of the warning flag 01 is inserted, the metal spring piece 116 can be pressed and opened smoothly.

[0023] On the other hand, Figure 2 and Figure 3As shown, the lower end of the rocker arm 103 is rotatably connected to the middle plate 105 via a fixed shaft 112, and the portion above the fixed shaft 112 but still in the lower half of the rocker arm 103 is also rotatably connected to the secondary connecting member 110 via a movable shaft 111, the secondary connecting member 110 is movably connected to the primary connecting member 108 via a telescopic connecting member 109, the primary connecting member 108 is rotatably connected to one end of the rotating plate 107, and the other end of the rotating plate 107 is connected to the output shaft of the driving motor 106. Therefore, the normal rotation of the output shaft of the driving motor 106 can drive the rocker arm 103 to perform periodic reciprocating swinging motion through the rotating plate 107, the primary connecting member 108, the telescopic connecting member 109, and the secondary connecting member 110.

[0024] The key point is that the telescopic connector 109 is telescopically connected to the primary connector 108 and the secondary connector 110, and the primary connector 108 and the secondary connector 110 are sleeved on the telescopic connector 109 and fixed at the port by nuts. In addition, the lower half of the rocker 103 is also provided with a movable groove 113, and the movable shaft 111 is movably connected in the movable groove 113, and the lower half of the rocker 103 is also provided with a plurality of limit slots 114, and the limit card strip 115 is slidably connected in the limit slot 114 to limit the movable shaft 111 from sliding in the movable groove 113. The position of the movable shaft 111 can be adjusted by pulling out the limit card strip 115, and the movable shaft 111 can be limited after being inserted so that it can only rotate.

[0025] Therefore, the cooperation of the two can effectively adjust the swing amplitude and swing speed of the joystick 103, thereby adapting to different warning flags 01, and avoiding the problem of the flag being difficult to unfold due to the warning flag 01 being too large and the swing amplitude being too small.

[0026] When in use, the flagpole of the warning flag 01 is inserted into the rocker 103, and the metal spring 116 squeezes and fixes the flagpole of the warning flag 01. Then, according to the size of the warning flag 01 or the weight of the flag, the swing amplitude and swing speed of the rocker 103 are adjusted.

[0027] When adjusting, loosen the nuts at the ports of the primary connector 108 and the secondary connector 110, adjust the length of the telescopic connector 109, then pull out the limit clip 115, adjust the position of the movable shaft 111, and then insert the limit clip 115 after adjustment, finally realizing the adjustment of the swing amplitude and swing speed of the rocker 103.

[0028] Finally, the driving motor 106 is started, and the output shaft of the driving motor 106 rotates normally, so that the rocker 103 can be driven to perform periodic reciprocating swinging motion through the rotating plate 107, the primary connecting member 108, the telescopic connecting member 109, and the secondary connecting member 110, so as to achieve the effect of waving a flag to warn.

[0029] Based on the above, the utility model is provided with a metal spring inside the rocker to apply elastic force to fix warning flags of different sizes, and the transmission connecting piece between the driving motor and the rocker is configured to be able to be extended and shortened, and the movable shaft connecting the rocker and the transmission connecting piece is movable, so that the swing amplitude of the rocker can be adjusted to adapt to different warning flags.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0031] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
