Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a self-propelled wing protection unmanned aerial vehicle and a manufacturing method thereof. Background Art

[0002] The rotor is an important component of a drone. During the flight of a drone, the rotor plays a dual role of generating lift and pull. In order to ensure that the rotor does not come into contact with obstacles and cause damage to the rotor when rotating at high speed, a protective device is generally installed on the outside of the rotor to protect the rotor.

[0003] The existing patent announcement number CN202223494823.3 discloses a rotor protection device for an unmanned aerial vehicle, including a top plate, and also includes a protection component, an adjustment component and an installation component. The protection component includes multiple groups of fixing rods, and the multiple groups of fixing rods are equidistantly distributed on the outer side of the top plate, and the middle parts of two adjacent groups of the fixing rods are provided with a protection part; the adjustment component is located on the side of the top plate close to the rotor; the installation component is located at the end of the fixing rod away from the top plate, and the installation component is located in the middle position of the multiple groups of fixing rods. By arranging multiple groups of fixing rods and telescopic protection frames, the multiple groups of fixing rods are connected to the telescopic protection frames end to end to form a protective cover for protecting the rotor, and the rotor is wrapped therein, which can achieve comprehensive protection around the rotor, effectively avoiding the situation where the rotor is damaged by contact with obstacles when rotating at high speed, and ensuring the normal flight of the unmanned aerial vehicle.

[0004] Although the above-mentioned UAV rotor protection device can improve the protection effect of the rotor, the rotor protection device is connected to the UAV's arm in a fixed manner. When the rotor protection structure is added, the take-off weight of the UAV increases. When the UAV's rotor is not affected by the outside in an open area, the UAV's range becomes shorter. When the device is protecting the UAV's rotor, its sliding bar is located at the bottom of the UAV's rotor. When the rotor rotates downward to generate airflow, the sliding bar is likely to affect the airflow, so the lifting force of the UAV is easily affected. For this reason, we propose a self-rotating wing protection UAV and a manufacturing method thereof, which facilitates the scene change protection of the UAV's rotor, does not protect the UAV when it is in an open area, reduces the load to increase the UAV's range, and increases the rotor protection of the UAV in areas with complex environments. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a self-propelled wing protection UAV and a manufacturing method thereof, which facilitates the protection of the UAV's rotor during flight scene change.

[0006] The technical solution adopted by the present invention to solve its technical problems is a rotary-wing protection UAV and a manufacturing method thereof, comprising a UAV body and an arm, wherein a protection mechanism is installed at the outer wall of the arm, and the protection mechanism is composed of a concave block, a T-block, a vertical plate, a cross bar, a ring body, a plug plate and a slot combination. A T-block is installed at the shell wall of the arm by bolts, a group of symmetrical slots are opened at the block wall of the T-block, a group of symmetrical plug plates are welded at the groove of the concave block, and the plug plates are located in the slots, a vertical plate is fixedly installed on the top of the concave block, a cross bar is welded at the plate wall of the vertical plate, and a ring body is welded at the other end of the cross bar.

[0007] By adopting the above technical scheme, when protecting the rotor of the drone body, after the external bolts are passed through the T-block, the external bolts are connected to the arm of the drone body to fix the T-block. A group of symmetrical slots are opened at the T-block, and a group of symmetrical plug plates are welded at the groove of the concave block. The plug plates are inserted into the slots to connect the T-block with the concave block. A vertical plate is fixedly installed on the top of the concave block, and a cross bar is welded at the plate wall of the vertical plate. A ring body is welded at the other end of the cross bar. The size of the ring body is larger than the wing size of the drone body, and the height of the ring body is the same as the height of the wing of the drone body. After the ring body is sleeved on the wing of the drone body, protection is achieved around the wing of the drone body.

[0008] Specifically, it also includes a connecting mechanism, and the connecting mechanism is installed on the block wall of the concave block.

[0009] By adopting the above technical solution, the concave block and the T-block can be conveniently connected and fixed through the connecting mechanism.

[0010] Specifically, the connecting mechanism is composed of a concave frame, an insertion rod, a positioning groove, a through groove, a connecting plate, a limit ring, a spring sleeve and a positioning block. The block wall of the concave block is connected with a connecting plate by bolts, the concave frame is welded at the plate wall of the connecting plate, the frame wall of the concave frame is plugged with an insertion rod, a limit ring is welded at the rod wall of the insertion rod, the insertion rod passes through the spring sleeve, and a positioning block is welded at the other end of the insertion rod. Through grooves are provided at the block wall of the concave block and the plate wall of the connecting plate, the positioning block passes through the through groove, and a positioning groove is provided at the block wall of the positioning block.

[0011] By adopting the above technical scheme, when the concave block and the T-block are connected and fixed, a connecting plate is connected to the block wall of the concave block by bolts, and a concave frame is welded at the plate wall of the connecting plate. Since a plug rod is plugged into the frame wall of the concave frame, a person pulls the plug rod. Since a limiting ring is welded at the rod wall of the plug rod, a positioning block is welded at the other end of the plug rod. The plug rod passes through the spring sleeve. After the plug rod is pulled, the positioning block squeezes the spring sleeve. After the person loosens the plug rod, the spring sleeve pushes the positioning block to move, so that after the positioning block passes through the through slot again, the positioning block is inserted into the positioning slot at the T-block, thereby realizing the connection and reinforcement of the concave block and the T-block.

[0012] Specifically, the cross-sectional dimension of the positioning groove is the same as that of the through groove, the positioning block is located in the positioning groove, the spring sleeve is located between the positioning block and the limiting ring, and the positioning block, spring sleeve and limiting ring are all located in the groove of the concave frame.

[0013] By adopting the above technical solution, the cross-sectional dimension of the positioning groove is the same as the cross-sectional dimension of the through groove, so that after the positioning block is inserted into the positioning groove and the through groove, the positioning block is limited and fixed, and then the concave block and the T-block are connected and fixed in the through groove and the positioning groove by the positioning block, so that the ring body is fixed at the rotor to achieve protection of the rotor.

[0014] Specifically, two groups of symmetrical arms are installed on the shell wall of the drone body, and motors are installed on the shell walls of the two groups of arms through bolts. A rotating shaft is installed at the output end of the motor, and a rotor is installed at the other end of the rotating shaft.

[0015] By adopting the above technical solution, when the drone body is taking off, since two sets of symmetrical walls are installed on the shell wall of the drone body, after the motor is fixedly connected through the arm, since a rotating shaft is installed at the output end of the motor, the drone body provides power and control signals to the motor, so that the motor drives the rotating shaft at its output end to rotate, and the rotating shaft then drives the rotor to rotate. When the rotor rotates, airflow is generated downward, thereby generating thrust upward, thereby realizing the ascent of the drone body.

[0016] Specifically, the rotor is located in the ring body, and the height of the rotor is the same as the height of the ring body.

[0017] By adopting the above technical solution, the rotor is located in the ring body, so that the ring body can protect the surroundings of the rotor. The height of the rotor is the same as the height of the ring body, which prevents the exposed rotor from contacting external objects and causing damage.

[0018] Specifically, a frame for supporting the drone body is installed at the bottom of the drone body.

[0019] By adopting the above technical solution, the drone body can be supported by the frame, so that the drone body can be placed when landing.

[0020] Specifically, when protecting the rotor of the drone body, after the external bolts are passed through the T-block, the external bolts are connected to the arm of the drone body to fix the T-block. A group of symmetrical slots are opened at the T-block, and a group of symmetrical plug-ins are welded at the groove of the concave block. The plug-ins are inserted into the slots to connect the T-block with the concave block. A vertical plate is fixedly installed on the top of the concave block, and a cross bar is welded at the wall of the vertical plate. A ring body is welded at the other end of the cross bar. The size of the ring body is larger than the wing size of the drone body, and the height of the ring body is the same as the height of the wing of the drone body. After the ring body is sleeved on the wing of the drone body, protection is achieved around the wing of the drone body, and then the T-block is fixed. When separating from the concave block, a connecting plate is connected to the block wall of the concave block by bolts, and a concave frame is welded at the plate wall of the connecting plate. Since a plug rod is plugged into the frame wall of the concave frame, a person pulls the plug rod. Since a limiting ring is welded at the rod wall of the plug rod, a positioning block is welded at the other end of the plug rod, and the plug rod passes through the spring sleeve. After pulling the plug rod, the positioning block squeezes the spring sleeve, and the positioning block is separated from the positioning groove and the through groove, so that the concave block and the T-block are separated. When the T-block and the concave block are connected and reinforced, after the person loosens the plug rod, the spring sleeve pushes the positioning block to move, so that after the positioning block passes through the through groove again, the positioning block is inserted into the positioning groove at the T-block, so that the concave block and the T-block are connected and reinforced.

[0021] By adopting the above technical solution, when the drone body protects the rotor of the drone body in different scenes, when the rotor of the drone body needs to be protected, the external bolts are passed through the T-block, so that the external bolts are connected to the arm of the drone body to fix the T-block. A group of symmetrical slots are opened at the T-block, and a group of symmetrical plug-ins are welded at the groove of the concave block. The plug-ins are inserted into the slots, the T-block is connected to the concave block, and then the connection between the T-block and the concave block is reinforced. After loosening the insertion rod, the spring sleeve pushes the positioning block to move, so that the positioning block passes through the through slot again, and then is inserted into the positioning slot at the T-block to connect and reinforce the concave block and the T-block. A vertical plate is fixedly installed on the top of the concave block, a horizontal bar is welded at the wall of the vertical plate, and a ring body is welded at the other end of the horizontal bar. The size of the ring body is larger than the wing size of the drone body, and the height of the ring body is the same as the height of the wing of the drone body. After the ring body is sleeved on the wing of the drone body, protection is achieved around the wing of the drone body.

[0022] When the range of the UAV body is increased in an open area and there is no need to protect the rotor of the UAV body, the T-block and the concave block are separated. A connecting plate is connected to the block wall of the concave block by bolts, and a concave frame is welded to the plate wall of the connecting plate. Since a plug rod is plugged into the frame wall of the concave frame, a person pulls the plug rod. Since a limiting ring is welded on the rod wall of the plug rod, a positioning block is welded on the other end of the plug rod. The plug rod passes through the spring sleeve. After the plug rod is pulled, the positioning block squeezes the spring sleeve, and the positioning block is disengaged from the positioning groove and the through groove, so that the concave block and the T-block are separated, thereby facilitating the removal of the ring body, reducing the load of the UAV body, and increasing the range of the UAV body.

[0023] Beneficial effects of the present invention:

[0024] (1) The present invention discloses a kind of self-propelled wing protection drone and its manufacturing method. When the drone body protects the rotor of the drone body in different scenes, when the rotor of the drone body needs to be protected, after the external bolts are passed through the T-block, the external bolts are connected to the arm of the drone body to fix the T-block. A group of symmetrical slots are provided at the T-block, and a group of symmetrical plug plates are welded at the groove of the concave block. The plug plates are inserted into the slots to connect the T-block and the concave block. When the connection between the T-block and the concave block is reinforced, after the personnel loosens the plug rod, the spring sleeve pushes the positioning block to move, so that after the positioning block passes through the through slot again, the positioning block is inserted into the positioning slot at the T-block to connect and reinforce the concave block and the T-block. A vertical plate is fixedly installed on the top of the block, a horizontal bar is welded to the plate wall of the vertical plate, and a ring body is welded to the other end of the horizontal bar. The size of the ring body is larger than the wing size of the drone body, and the height of the ring body is the same as the wing height of the drone body. After the ring body is sleeved on the wing of the drone body, protection is achieved around the wing of the drone body. When the drone body is taking off, two sets of symmetrical walls are installed on the shell wall of the drone body. After the motor is fixedly connected through the arm, since a shaft is installed at the output end of the motor, power and control signals are provided to the motor through the drone body, so that the motor drives the shaft at its output end to rotate, and the shaft then drives the rotor to rotate. When the rotor rotates, airflow is generated downward, thereby generating thrust upward, thereby achieving the ascent of the drone body.

[0025] (2) The present invention discloses a self-propelled wing protection drone and a method for making the same. When the range of the drone body is increased in an open area and when there is no need to protect the rotor of the drone body, the T-block and the concave block are separated. The block wall of the concave block is connected with a connecting plate by bolts, and a concave frame is welded at the plate wall of the connecting plate. Since a plug rod is plugged into the frame wall of the concave frame, a person pulls the plug rod. Since a limiting ring is welded at the rod wall of the plug rod, a positioning block is welded at the other end of the plug rod. The plug rod passes through a spring sleeve. After the plug rod is pulled, the positioning block squeezes the spring sleeve, and the positioning block is disengaged from the positioning groove and the through groove, thereby separating the concave block from the T-block, making it easier to remove the ring body, reduce the load on the drone body, and increase the range of the drone body.

A group of symmetrical plug plates 606 are welded at the groove of the concave block 601, and the plug plates 606 are located in the slots 607.

[0036] When in use, when protecting the rotor 5 of the drone body 1, after the external bolts are passed through the T-block 602, the external bolts are connected to the arm 2 of the drone body 1 to fix the T-block 602. A group of symmetrical slots 607 are opened at the T-block 602, and a group of symmetrical plug plates 606 are welded at the groove of the concave block 601. The plug plates 606 are inserted into the slots 607 to connect the T-block 602 with the concave block 601. A vertical plate 603 is fixedly installed on the top of the concave block 601, and a cross bar 604 is welded at the plate wall of the vertical plate 603. A ring body 605 is welded at the other end of the cross bar 604. The size of the ring body 605 is larger than the wing size of the drone body 1, and the height of the ring body 605 is the same as the wing height of the drone body 1. After the ring body 605 is sleeved on the wing of the drone body 1, protection is achieved around the wing of the drone body 1.

[0037] In order to connect and fix the concave block 601 and the T-block 602, for example, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a connecting mechanism 7, and the connecting mechanism 7 is installed on the block wall of the concave block 601.

[0038] When in use, the concave block 601 and the T-block 602 are conveniently connected and fixed via the connecting mechanism 7 .

[0039] In order to insert the T-block 602 into the groove of the concave block 601, for example, Figure 3 , Figure 4 and Figure 5As shown, the connecting mechanism 7 is composed of a concave frame 701, an insert rod 702, a positioning groove 703, a through groove 704, a connecting plate 705, a limiting ring 706, a spring sleeve 707 and a positioning block 708. The block wall of the concave block 601 is connected with a connecting plate 705 by bolts, the plate wall of the connecting plate 705 is welded with a concave frame 701, the frame wall of the concave frame 701 is plugged with an insert rod 702, a limiting ring 706 is welded at the rod wall of the insert rod 702, the insert rod 702 passes through the spring sleeve 707, and the other end of the insert rod 702 is welded with a positioning block 708. The block wall of the concave block 601 and the plate wall of the connecting plate 705 are both provided with a through groove 704, the positioning block 708 passes through the through groove 704, and the block wall of the positioning block 708 is provided with a positioning groove 703.

[0040] When in use, when the concave block 601 and the T-block 602 are connected and fixed, the block wall of the concave block 601 is connected with a connecting plate 705 by bolts, and a concave frame 701 is welded at the plate wall of the connecting plate 705. Since the frame wall of the concave frame 701 is plugged with a plug rod 702, a person pulls the plug rod 702. Since a limiting ring 706 is welded on the rod wall of the plug rod 702, a positioning block 708 is welded at the other end of the plug rod 702. The plug rod 702 passes through the spring sleeve 707. After the plug rod 702 is pulled, the positioning block 708 squeezes the spring sleeve 707. After the person loosens the plug rod 702, the spring sleeve 707 pushes the positioning block 708 to move, so that after the positioning block 708 passes through the through groove 704 again, the positioning block 708 is inserted into the positioning groove 703 at the T-block 602, so as to realize the connection and reinforcement of the concave block 601 and the T-block 602.

[0041] In order to insert the positioning block 708 into the positioning groove 703, for example, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cross-sectional dimension of the positioning groove 703 is the same as the cross-sectional dimension of the through groove 704, the positioning block 708 is located in the positioning groove 703, the spring sleeve 707 is located between the positioning block 708 and the limiting ring 706, and the positioning block 708, the spring sleeve 707 and the limiting ring 706 are all located in the groove of the concave frame 701.

[0042] When in use, the cross-sectional dimension of the positioning groove 703 is the same as the cross-sectional dimension of the through groove 704, so that after the positioning block 708 is inserted into the positioning groove 703 and the through groove 704, the positioning block 708 is limited and fixed, and then the positioning block 708 is used in the through groove 704 and the positioning groove 703 to connect and fix the concave block 601 and the T-block 602, thereby fixing the ring body 605 at the rotor 5 to protect the rotor 5.

[0043] When the drone body 1 is launched, for example, Figure 1 and Figure 6 As shown, two groups of symmetrical arms 2 are installed on the shell wall of the drone body 1, and motors 3 are installed on the shell walls of the two groups of arms 2 through bolts. A rotating shaft 4 is installed at the output end of the motor 3, and a rotor 5 is installed at the other end of the rotating shaft 4.

[0044] During use, when the drone body 1 is taking off, since two sets of symmetrical walls are installed on the shell wall of the drone body 1, after the motor 3 is fixedly connected through the arm 2, since the output end of the motor 3 is installed with a rotating shaft 4, the drone body 1 provides power and control signals to the motor 3, so that the motor 3 drives the rotating shaft 4 at its output end to rotate, and the rotating shaft 4 then drives the rotor 5 to rotate. When the rotor 5 rotates, an airflow is generated downward, thereby generating thrust upward, thereby realizing the ascent of the drone body 1.

[0045] For example, Figure 1 As shown, the rotor 5 is located inside the ring body 605 , and the height of the rotor 5 is the same as the height of the ring body 605 .

[0046] When in use, the rotor 5 is located inside the ring body 605, so that the ring body 605 protects the periphery of the rotor 5. The height of the rotor 5 is the same as that of the ring body 605, so as to prevent the rotor 5 from being exposed and contacting with external objects and causing damage.

[0047] For example, Figure 1 and Figure 5 As shown, a frame 8 for supporting the drone body 1 is installed at the bottom of the drone body 1.

[0048] When in use, the frame 8 can support the drone body 1 so that the drone body 1 can be placed when landing.

[0049] In order to prepare the front carpet of the car, for example, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when protecting the rotor 5 of the drone body 1, after the external bolts are passed through the T-block 602, the external bolts are connected to the arm 2 of the drone body 1 to fix the T-block 602. A group of symmetrical slots 607 are opened at the T-block 602, and a group of symmetrical plug plates 606 are welded at the groove of the concave block 601. The plug plates 606 are inserted into the slots 607 to connect the T-block 602 and the concave block 601. A vertical plate 603 is fixedly installed on the top, a horizontal bar 604 is welded to the plate wall of the vertical plate 603, and a ring body 605 is welded to the other end of the horizontal bar 604. The size of the ring body 605 is larger than the wing size of the drone body 1, and the height of the ring body 605 is the same as the wing height of the drone body 1. After the ring body 605 is sleeved on the wing of the drone body 1, the wing of the drone body 1 is protected. When the T-block 602 is separated from the concave block 601, the concave block The block wall of 601 is connected with a connecting plate 705 by bolts, and a concave frame 701 is welded on the plate wall of the connecting plate 705. Since a plug rod 702 is plugged and connected to the frame wall of the concave frame 701, a person pulls the plug rod 702. Since a limiting ring 706 is welded on the rod wall of the plug rod 702, a positioning block 708 is welded on the other end of the plug rod 702. The plug rod 702 passes through the spring sleeve 707. After the plug rod 702 is pulled, the positioning block 708 squeezes the spring sleeve 707, and the positioning block 708 squeezes the spring sleeve 707. 08 is disengaged from the positioning groove 703 and the through groove 704 to separate the concave block 601 from the T-block 602. When the connection between the T-block 602 and the concave block 601 is reinforced, the personnel loosens the insertion rod 702, and the spring sleeve 707 pushes the positioning block 708 to move, so that the positioning block 708 passes through the through groove 704 again, and then the positioning block 708 is inserted into the positioning groove 703 at the T-block 602, so that the concave block 601 and the T-block 602 are connected and reinforced.

[0050] When in use, the drone body 1 protects the rotor 5 of the drone body 1 in different scenarios. When the rotor 5 of the drone body 1 needs to be protected, the external bolts are passed through the T-block 602, so that the external bolts are connected to the arm 2 of the drone body 1 to fix the T-block 602. A group of symmetrical slots 607 are opened at the T-block 602, and a group of symmetrical plug plates 606 are welded at the groove of the concave block 601. The plug plates 606 are inserted into the slots 607, and the T-block 602 is connected to the concave block 601. When the connection between the T-block 602 and the concave block 601 is reinforced, after the personnel loosens the plug rod 702, the spring sleeve 707 pushes the positioning block 708 to move, so that the positioning block 708 passes through the through groove 704 again, and then the positioning block 708 is inserted into the positioning groove 703 at the T-block 602, so as to connect and reinforce the concave block 601 with the T-block 602. A vertical plate 603 is fixedly installed on the top of the concave block 601, and a cross bar 604 is welded at the plate wall of the vertical plate 603. A ring body 605 is welded at the other end of the cross bar 604. The size of the ring body 605 is larger than the wing size of the drone body 1, and the height of the ring body 605 is the same as the wing height of the drone body 1. After the ring body 605 is sleeved on the wing of the drone body 1, protection is achieved around the wing of the drone body 1.

[0051] When the range of the drone body 1 is increased in an open area and there is no need to protect the rotor 5 of the drone body 1, when the T-block 602 is separated from the concave block 601, a connecting plate 705 is connected to the block wall of the concave block 601 by bolts, and a concave frame 701 is welded to the plate wall of the connecting plate 705. Since the wall of the concave frame 701 is plugged with a plug rod 702, a person pulls the plug rod 702. Since a limiting ring 706 is welded on the rod wall of the plug rod 702, a positioning block 708 is welded on the other end of the plug rod 702, and the plug rod 702 passes through the spring sleeve 707. After the plug rod 702 is pulled, the positioning block 708 squeezes the spring sleeve 707, and the positioning block 708 is separated from the positioning groove 703 and the through groove 704, so that the concave block 601 and the T-block 602 are separated, thereby facilitating the removal of the ring body 605, reducing the load of the drone body 1, and increasing the range of the drone body 1.

[0052] When the protection of the rotor 5 of the drone body 1 is prepared for use, the drone body 1 protects the rotor 5 of the drone body 1 in different scenarios. When the rotor 5 of the drone body 1 needs to be protected, the external bolts are passed through the T-block 602, so that the external bolts are connected to the arm 2 of the drone body 1 to fix the T-block 602. A group of symmetrical slots 607 are opened at the T-block 602, and a group of symmetrical plug plates 606 are welded at the groove of the concave block 601. The plug plates 606 are inserted into the slots 607 to connect the T-block 602 and the concave block 601. When the connection between the T-block 602 and the concave block 601 is reinforced, after the personnel loosens the plug rod 702, the spring sleeve 707 pushes the positioning block 708 to move, so that the positioning block 708 passes through the through slot 704 again, and then the positioning block 708 is inserted into the positioning slot 703 at the T-block 602 to achieve the concave block 601 and the T-block. 602 is connected and reinforced, a vertical plate 603 is fixedly installed on the top of the concave block 601, a cross bar 604 is welded on the plate wall of the vertical plate 603, and a ring body 605 is welded on the other end of the cross bar 604. The size of the ring body 605 is larger than the wing size of the drone body 1, and the height of the ring body 605 is the same as the wing height of the drone body 1. After the ring body 605 is sleeved on the wing of the drone body 1, the wing of the drone body 1 is protected. When the drone body 1 is ascending, since two sets of symmetrical machine walls are installed on the shell wall of the drone body 1, after the motor 3 is fixedly connected through the machine arm 2, since the output end of the motor 3 is installed with a rotating shaft 4, the drone body 1 provides power and control signals to the motor 3, so that the motor 3 drives the rotating shaft 4 at its output end to rotate, and the rotating shaft 4 then drives the rotor 5 to rotate. When the rotor 5 rotates, airflow is generated downward, so that thrust is generated upward, so that the drone body 1 is ascended;

[0053] When the range of the drone body 1 is increased in an open area and there is no need to protect the rotor 5 of the drone body 1, when the T-block 602 is separated from the concave block 601, a connecting plate 705 is connected to the block wall of the concave block 601 by bolts, and a concave frame 701 is welded to the plate wall of the connecting plate 705. Since the wall of the concave frame 701 is plugged with a plug rod 702, a person pulls the plug rod 702. Since a limiting ring 706 is welded on the rod wall of the plug rod 702, a positioning block 708 is welded on the other end of the plug rod 702, and the plug rod 702 passes through the spring sleeve 707. After the plug rod 702 is pulled, the positioning block 708 squeezes the spring sleeve 707, and the positioning block 708 is separated from the positioning groove 703 and the through groove 704, so that the concave block 601 and the T-block 602 are separated, thereby facilitating the removal of the ring body 605, reducing the load of the drone body 1, and increasing the range of the drone body 1.
