[0033] The launcher 4 drives the rotating rod 63 to rotate in the fixed block 62, so that the rotating rod 63 synchronously drives the brake disc 64 to rotate, and then aligns with the positioning rod 67 in turn through the socket 65, and uses the restoring force of the spring 69 to drive the positioning rod 67 to insert into the socket 65, so as to achieve the purpose of adjusting the launch angle of the launcher 4, which can facilitate the staff to adjust the launch angle of the launcher 4, and at the same time solve the problem that the launch angle of the launcher 4 cannot be adjusted when the electric adjustment system is damaged, so that it can keep working for a long time, and then slide the support plate 61 and the launcher 4 into the storage bin 71, and then use the spring The restoring force of 69 drives the plug block 75 to be inserted into the slot 76, thereby achieving the purpose of storing the launcher 4 and preventing the launcher 4 from rubbing and colliding with external objects, which may cause the launcher 4 or the launch tube 5 to be damaged and unusable. Then, by turning the hand wheel 84, the hand wheel 84 drives the bidirectional screw rod 82 to rotate in the movable bin 81, and the bidirectional screw rod 82 acts on the two sets of transmission blocks 83, so that the two sets of transmission blocks 83 are attached to and cover the storage bin 71, thereby effectively reducing the dust on the launcher 4 and preventing mosquitoes from gnawing on the wires on the launcher 4, causing the launcher 4 to be damaged.

[0034] The adjustment component 6 includes a support plate 61 arranged in the support seat 1, and two groups of fixed blocks 62 are symmetrically arranged on the support plate 61. A rotating rod 63 rotates in the fixed block 62, and brake discs 64 are arranged at the front and rear ends of the rotating rod 63. The outer wall of the brake disc 64 is provided with multiple groups of jacks 65. A fixed frame 66 is arranged on the support plate 61 on the right side of the brake disc 64, and a positioning rod 67 slides in the fixed frame 66. A slide plate 68 is arranged on the surface of the positioning rod 67, and the slide plate 68 slides in the fixed frame 66. A spring 69 is wound on the surface of the positioning rod 67 on the right side of the slide plate 68. Two groups of guide rings 610 are symmetrically arranged on the support plate 61 on the left surface of the fixed block 62, and the bracket 3 slides on the guide ring 610.

[0035] When in use, first pull the positioning rod 67 in the direction away from the bracket 3, so that the positioning rod 67 drives the slide plate 68 to slide in the fixed frame 66, and one end of the positioning rod 67 slides out from the insertion hole 65, and then slides into the fixed frame 66, while the slide plate 68 continuously presses the spring 69 against the inner wall of the fixed frame 66, and then rotate the bracket 3, so that the bracket 3 drives the rotating rod 63 to rotate in the fixed block 62, and when the launch angle of the launcher 4 is turned to a suitable position, the positioning rod 67 is released again at this time, and the restoring force of the spring 69 is used to push the slide plate 68 to return to the fixed frame 66 and slide, and the slide plate 68 drives the positioning rod 67 to be inserted into another set of insertion holes 65, so as to achieve the purpose of adjusting the launch angle of the launcher 4.

[0036] In order to facilitate the staff to adjust the launch angle of the launcher 4, twelve groups of sockets 65 are provided, and the twelve groups of sockets 65 are designed with equal spacing. The positioning rod 67 is set to a shape that is compatible with the sockets 65. Through this design, the rotating rod 63 is rotated in the fixed block 62, so that the rotating rod 63 synchronously drives the brake disc 64 to rotate, and then aligns with the positioning rod 67 in turn through the socket 65, and uses the restoring force of the spring 69 to drive the positioning rod 67 to be inserted into the socket 65, thereby achieving the purpose of adjusting the launch angle of the launcher 4.

[0037] In order to ensure the stability of the spring 69 during use, one end of the spring 69 is welded to the surface of the slide plate 68, and the other end of the spring 69 is welded to the surface of the fixed frame 66. Through this design, by fixing the two ends of the spring 69, the spring 69 can be prevented from hitting the surface of the positioning rod 67 and causing noise pollution when the support seat 1 vibrates.

[0038] The storage assembly 7 includes a storage bin 71 opened in the support base 1, the support plate 61 slides in the storage bin 71, two sets of guide grooves 72 are symmetrically opened on the right side surface of the support base 1, the surface of the positioning rod 67 is provided with threads 73, and the threads 73 are threadedly connected with connecting plates 74, and the connecting plates 74 slide in the guide grooves 72, and two sets of slots 76 are symmetrically opened on the right side surface of the support base 1, and plug blocks 75 are provided on the outer walls of the connecting plates 74, and the plug blocks 75 are slidably connected to the slots 76.

[0039] When in use, first pull the positioning rod 67 so that the positioning rod 67 synchronously drives the plug block 75 to slide out of the plug block 75, then slide the support plate 61 into the storage bin 71, so that the support plate 61 drives the connecting plate 74 to slide in the guide groove 72, and slides the plug block 75 to align with another set of slots 76. At this time, the launcher 4 slides into the storage bin 71, and then release the positioning rod 67, and use the restoring force of the spring 69 to drive the plug block 75 to be inserted into the slot 76, thereby achieving the purpose of storing the launcher 4.

[0040] In order to ensure the stability of the support plate 61 when sliding up and down in the storage bin 71, the slot 76 is designed to be rectangular, and the part of the plug block 75 inserted into the slot 76 is set to a shape that matches the slot 76. Through this design, the plug block 75 can be inserted into the slot 76 so that the plug block 75 and the slot 76 are fully fitted together, thereby preventing the plug block 75 from shaking in the slot 76 and affecting the use of the transmitter 4.

[0041] In order to facilitate the staff to rotate the connecting plate 74, the connecting plate 74 is designed to be rectangular, and the outer wall of the connecting plate 74 is provided with anti-slip texture. Through this design, it is convenient for the staff to rotate the plug 75, and at the same time, the friction between the staff's hand and the connecting plate 74 is increased to prevent the hand from slipping when rotating the connecting plate 74.

[0043] When in use, by turning the hand wheel 84, the hand wheel 84 drives the bidirectional screw rod 82 to rotate in the movable bin 81, and the bidirectional screw rod 82 acts on the two sets of transmission blocks 83, so that the transmission blocks 83 move on the bidirectional screw rod 82 and gather toward the middle of the bidirectional screw rod 82. At the same time, the transmission block 83 synchronously drives the cover plate 86 to move through the connecting block 85 until the two sets of cover plates 86 are fitted together, thereby achieving the purpose of covering the storage bin 71 and preventing the launcher 4 from being damaged. When the launcher 4 is used, the hand wheel 84 is turned in the opposite direction to make the two sets of cover plates 86 slide out of the storage bin 71.

[0044] In order to facilitate the staff to understand the situation in the storage bin 71, the cover 86 is designed to be transparent, and a circle of rubber pads is provided on the surface of the cover 86 facing the support seat 1. Through this design, when the cover 86 blocks the storage bin 71, the staff can understand the situation of the storage bin 71 through the cover 86.

[0047] S2: When the support base 1 is moved or stored, the positioning rod 67 is pulled to synchronously drive the insert block 75 to slide out of the insert block 75, and then the support plate 61 is slid into the storage compartment 71, so that the support plate 61 drives the connecting plate 74 to slide in the guide groove 72, and the insert block 75 slides to align with another set of slots 76. At this time, the launcher 4 slides into the storage compartment 71, and then the positioning rod 67 is released, and the restoring force of the spring 69 is used to drive the insert block 75 to be inserted into the slot 76, so as to achieve the purpose of storing the launcher 4;

[0048] S3: When the launcher 4 is not in use, the hand wheel 84 is rotated to drive the bidirectional screw rod 82 to rotate in the movable bin 81, and the bidirectional screw rod 82 acts on the two sets of transmission blocks 83, so that the transmission blocks 83 move on the bidirectional screw rod 82 and gather toward the middle of the bidirectional screw rod 82. At the same time, the transmission block 83 synchronously drives the cover plate 86 to move through the connecting block 85 until the two sets of cover plates 86 are fitted together, thereby achieving the purpose of covering the storage bin 71 and preventing the launcher 4 from being damaged. When the launcher 4 is used, the hand wheel 84 is rotated in the opposite direction to slide the two sets of cover plates 86 out of the storage bin 71.

At the same time, the transmission block (83) drives the cover plate (86) to move synchronously through the connecting block (85) until the two sets of cover plates (86) are fitted together, thereby achieving the purpose of covering the storage bin (71) and preventing the launcher (4) from being damaged. When the launcher (4) is used, the hand wheel (84) is rotated in the opposite direction to slide the two sets of cover plates (86) out of the storage bin (71).
