Preferably, the locking spring 802 may be a coil spring, and the latch 80 is inserted into the locking spring 802. The first stopper 801 may be an annular flange formed on the latch 80, or the first stopper 801 is on the latch 80 side. A protruding portion formed on the wall; a first protruding portion is formed on the bottom surface of the mounting plate 101 facing the head 20, and the insertion hole is provided on the first protruding portion and is outside the first protruding portion and faces the insertion hole A second protruding portion is formed at the position, and the second protruding portion is the second stopping portion 1012. The first stopping portion 801 is located between the first protruding portion and the second protruding portion. The ends abut against the second protruding portion and the first stop portion 801, respectively, and further, under the action of the elastic force of the lock spring 802, the driving pin 80 moves into the slot.

Alternatively, the lock spring 802 is a torsion spring. At this time, the two ends of the torsion spring only need to abut against the first stop portion 801 and the second stop portion 1012, respectively, and the latch 80 can be driven by the elastic force of the torsion spring. Into the slot.

Preferably, a second guiding surface 701 is provided on the locking block 70, and the second guiding surface 701 extends from the end of the locking block 70 away from the end of the gimbal 20 toward the front end, and gradually approaches the side wall of the locking groove 1013 with the insertion hole, so that During the process of inserting the locking block 70 into the locking groove 1013, the end of the latch 80 facing the locking groove 1013 slides on the second guide surface 701, so as not to push the latch 80 against the end of the locking block 70, which prevents the locking block 70 from being inserted into Inside the locking slot 1013. It should be noted that the length of the latch 80 is set reasonably to ensure that when the locking block 70 is inserted into the lock groove 1013, the second guide surface 701 first contacts the latch 80 to prevent the latch 80 from being too long and the latch 80 against the top. At the end of the lock block 70, the lock block 70 is prevented from entering the lock groove 1013.

Continue referring to FIG. 5. Specifically, the locking device further includes an operating lever 90. A sliding hole is provided on the fuselage 10. The driving end of the operating lever 90 is disposed in the sliding hole, and the driving end is provided with a slanted surface 901. The latch 80 is provided with a slanted surface 901. The driving portion is such that when the operating lever 90 is pressed into the slide hole, the inclined surface 901 abuts against the driving portion to drive the latch 80 to move outside the locking groove 1013. By pushing the operating lever 90, the bolt 80 can be detached from the slot, thereby unlocking the gimbal 20 and the main body 10, and facilitating the disassembly of the gimbal 20.

Preferably, the center line of the sliding hole is perpendicular to the center line of the latch 80; the end of the operating lever 90 facing away from the driving end has an operating end, and the end of the inclined surface 901 facing the operating end is farther away from the locking groove 1013 than the end facing away from the operating end. When moving to the inside of the slide hole, the inclined surface 901 can drive the latch 80 to move away from the locking groove 1013, thereby disengaging the latch 80 from the slot on the locking block 70; after removing the locking block 70 from the locking groove 1013, release The operating lever 90 moves the latch 80 into the locking groove 1013 under the driving of the locking spring 802, at the same time, the driving portion abuts against the inclined surface 901, and further drives the operating lever 90 to protrude from the slide hole.

Specifically, there may be multiple driving parts in this embodiment. For example, the driving part may be a protrusion provided on a side wall of the latch 80, and the protrusion abuts on the inclined surface 901. In this embodiment, preferably, the driving part includes a driving hole provided on the latch 80, the driving end is penetrated in the driving hole, and the inclined surface 901 abuts against a side wall of the driving hole. The operation arm is disposed in the driving hole to prevent the operation arm from moving when the drone is working, which in turn causes the inclined surface 901 to be unable to contact the driving part.

Continue referring to FIG. 5. Preferably, the operating end of the operating lever 90 facing away from the driving end is provided with a pressing plate 902, and a surface area of the pressing plate 902 is larger than a cross-sectional area of the operating lever 90. The pressing plate 902 can increase the contact area with the operator's hand, thereby improving the comfort of pressing the operating lever 90.

Specifically, the installation process of the drone is as follows: firstly guide the guide portion 302 into the positioning hole, and then push the gimbal 20 toward the fuselage 10 so that the cylinder 301 passes through the positioning hole and the pin on the gimbal 20 It is also gradually inserted into the socket on the body 10, and at the same time, the locking block 70 gradually enters the locking groove 1013; when the tapered guide portion 302 is fitted with the tapered surface in the positioning hole, the pin is fully inserted Into the socket, and the slot on the locking block 70 is facing the jack. Under the elastic force of the locking spring 802, the pin 80 moves into the locking groove 1013 and the end of the pin 80 passes through the slot. The pin 80 can prevent The locking block 70 moves to the outside of the locking groove 1013, thereby achieving the locking of the gimbal 20 and the main body 10.

When disassembling, press the pressing plate 902 on the operating lever 90 to move the operating lever 90 toward the inside of the sliding hole, and at the same time, the inclined surface 901 abuts against the side wall of the driving hole to drive the latch 80 to move away from the locking groove 1013. Disengage the latch 80 from the slot, and then lock the locking block 70, and then pull the gimbal 20 away from the fuselage 10 to disengage the cylinder 301 from the positioning hole, and at the same time disengage the pin from the socket In order to achieve disassembly between the gimbal 20 and the main body 10.
