In order to explain the technical contents, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

The most key concept of the invention is that the paddle 1 is connected with two movable buckles, a spring 4 is arranged between the two buckles, and the disassembly or fixation of the paddle 1 can be realized through the compression or extension of the spring 4.

Referring to fig. 1 and 2, a fixed paddle assembly includes a paddle 1, a first buckle 2, a second buckle 3, a spring 4, a base 7 and a motor 9, where the paddle 1 includes a paddle 11 and a paddle connecting seat 12 integrally formed with the paddle 11, two sides of the paddle connecting seat 12 are respectively provided with a pair of hooks 13, and the hooks 13 on two sides of the paddle connecting seat 12 are respectively matched with the first buckle 2 and the second buckle 3; the first buckle 2 and the second buckle 3 are movably arranged on the base 7, and the spring 4 is connected between the first buckle 2 and the second buckle 3 in a propping manner; the base 7 is fixedly connected with the motor 9.

From the above description, the beneficial effects of the present invention are: when the clamping hook of the blade connecting seat is clamped between the first clamping hook and the second clamping hook, the spring can provide elasticity to ensure that the clamping hook is firmly clamped with the first clamping hook and the second clamping hook, and the fixed blade assembly cannot be loosened in the flying process; when the oar needs to be taken down, only need compress the spring can make first buckle and second buckle break away from the pothook, it is very convenient to dismantle.

Further, the inner sides of the first buckle 2 and the second buckle 3 are oppositely arranged; the first buckle 2 and the second buckle 3 are both provided with stepped through holes 22, and the inner hole diameter is larger than the outer hole diameter.

As can be seen from the above description, the large hole on the inner side can be used for mounting the spring, and the end face of the small hole can prop against the spring to limit the spring.

Further, the end of the inner side hole of the stepped through hole 22 of the first buckle 2 and the second buckle 3 is provided with a chamfer.

As can be seen from the above description, the chamfer is arranged at the end part of the inner side hole, so that the spring can be conveniently installed.

Further, a base through hole 72 is arranged on the base 7 at a position corresponding to the stepped through hole 22; the spring shaft 5 is further included, and the spring shaft 5 penetrates through the base through hole 72, the spring 4 and the stepped through holes 22 of the first buckle 2 and the second buckle 3.

From the above description, the spring shaft can prevent the spring from shifting up and down, left and right or being excessively compressed to be separated from the stepped through hole in the compression process, and the stability of the structure is ensured.

Further, the device also comprises a base sleeve 8, and the base sleeve 8 is sleeved outside the base 7.

As can be seen from the above description, in one aspect, the base sleeve can block the two ends of the through hole of the base, thereby fixing the spring shaft.

Furthermore, two opposite side walls of the base 7 are respectively provided with a positioning hole 71, the outer sides of the first buckle 2 and the second buckle 3 are both provided with a positioning protrusion 21, and the positioning protrusion 21 is clamped in the positioning hole 71 and extends out of the positioning hole 71.

According to the description, the first buckle and the second buckle can be preliminarily fixed on the base through the matching of the positioning hole and the positioning bulge, and the spring is arranged between the first buckle and the second buckle, so that the first buckle and the second buckle can be tightly pressed against the base; because the location arch stretches out outside the locating hole, when the oar needs to be dismantled, the accessible presses the location arch outside the locating hole, can compress the spring to make oar and buckle break away from.

Further, the base 7 is connected with the motor 9 through two screws 6.

Furthermore, the base 7 is provided with four protruding strips 74, the four protruding strips 74 are respectively disposed on two sides of the first fastener 2 and two sides of the second fastener 3, and the extending directions of the four protruding strips 74 are the same as the setting direction of the spring 4.

It can be known from the above description that the four convex strips can limit the first buckle and the second buckle, so that the first buckle and the second buckle can only move along the direction of the spring in the process of the change of the compression state of the spring, and the deviation in other directions can not occur.

Furthermore, the hook 13 includes a clamping end, and the inner side of the clamping end is an inclined plane.

According to the above description, when the oar is installed, the oar is placed on the first buckle and the second buckle and is pressed down, the inner side of the clamping end is in contact with the outer side of the first buckle and the outer side of the second buckle, and under the compression of the inner side inclined plane, the first buckle and the second buckle can gradually move inwards to compress the spring and finally are clamped in the clamping hook.

Further, a guide 73 is further disposed on the base 7, and the guide 73 is disposed between the two pairs of hooks 13.

The guide piece can guide the paddle, and when the paddle is installed, the two pairs of clamping hooks are pressed downwards along the guide piece, so that the clamping hooks and the buckles can be quickly aligned and installed.
