As a modification of the above, the number of the first fastening holes 114 and the third fastening holes 312 is three, and the three fastening holes are arranged in a triangular manner, and three second screws are arranged. It can be understood that the triangle is provided with the first fastening hole 114 and the third fastening hole 312, so that the three second screws can fix the bracket 100 and the connecting shell 310 together in a triangle shape, and according to the stability principle of the triangle, the design can ensure that the material consumption is minimum on the premise of ensuring the connection stability, thereby reducing the production cost and improving the installation efficiency.

In some embodiments of the present invention, the positioning device further includes a third positioning portion 340, the third positioning portion 340 includes a positioning table 341 and a plurality of positioning teeth 342, the positioning table 341 is connected to the connecting housing 310 and located on one side of the second mounting surface 311, each positioning tooth 342 is sequentially fixed to the positioning table 341 along the circumferential direction, and one end of the first positioning portion 120 away from the third positioning groove 313 is abutted to the positioning teeth 342.

Specifically, the third positioning portion 340 is disposed on a side of the connecting housing 310 away from the main housing 320, and includes a positioning table 341 in a disc shape or a ring shape, and positioning teeth 342 fixed on the positioning table 341 by way of integral molding or welding, and the positioning teeth 342 are circumferentially distributed along an edge of the positioning table 341 and disposed on a side of the third positioning groove 313 where the second notch 314 is disposed, and a gap 344 is present between two adjacent positioning teeth 342, so that the first positioning portion 120 can pass through the gap 344.

The first positioning portion 120 passing through the gap 344 rotates to a position between the third positioning groove 313 and the positioning tooth 342, and then one end of the positioning block 121 facing the third positioning groove 313 is embedded into the third positioning groove 313 to complete the primary positioning, and at this time, if the functional block 122 is not arranged in the first positioning portion 120, one end of the positioning block 121 facing the positioning tooth 342 directly abuts against the positioning tooth 342; if the functional block 122 is disposed in the first positioning portion 120, the functional block 122 abuts against the positioning teeth 342, and the larger area of the end surface of the functional block 122 can increase the contact area with the positioning teeth 342, so that the acting force of the positioning teeth 342 on the first positioning portion 120 is more stable. For convenience of description, the position of the first positioning portion 120 at this time is named as a preset position.

It should be understood that, in order to enable the positioning teeth 342 to apply a force to the first positioning portion 120 toward the third positioning slot 313, the positioning table 341 is connected to the connection housing 310 through an elastic member, which may be a leaf spring, a coil spring, or the like. It is understood that, when the elastic member is in a normal state, the distance between the side surface of the positioning tooth 342 facing the third positioning groove 313 and the bottom surface of the third positioning groove 313 away from the second notch 314 is smaller than the length of the first positioning portion 120 in the axial direction of the accommodating groove 113, so as to ensure that the positioning tooth 342 can provide a force to the first positioning portion 120 to face the third positioning groove 313 when the first positioning portion 120 is inserted into the third positioning groove 313. Meanwhile, the maximum deformation amount of the elastic element is greater than or equal to the maximum distance from the side surface of the positioning tooth 342 facing the third positioning slot 313 to the second notch 314 during the rotation of the first positioning portion 120, so as to ensure that the first positioning portion 120 can be smoothly screwed into the predetermined position without damaging the elastic element.

It can be understood that the design of the third positioning portion 340 effectively improves the stability of the bracket 100 when being connected to the motor 300, and ensures that the bracket 100 can still be stably connected to the motor 300 when the second screw is loosened.

As a modification of the above solution, a protrusion 343 is further disposed on the positioning teeth 342, and the protrusion 343 will abut against the first positioning portion 120 at the preset position, it can be understood that the protrusion 343 can further increase the acting force of the positioning teeth 342 on the first positioning portion 120, thereby improving the stability.

In some embodiments of the present invention, the third positioning groove 313 includes a first positioning surface 315 and a second positioning surface 316 disposed opposite to each other, a plane where the first positioning surface 315 is located intersects with a plane where the second positioning surface 316 is located on a side away from the second mounting surface 311, and a length of the first positioning surface 315 in an axial direction of the connecting housing 310 is greater than a length of the second positioning surface 316 in the axial direction of the connecting housing 310.

Specifically, the third positioning groove 313 with two openings has only one pair of inner walls, named as the first positioning surface 315 and the second positioning surface 316, which are opposite to each other, and compared with the bottom surface of the third positioning groove 313 away from the second notch 314, the first positioning surface 315 and the second positioning surface 316 are both inclined surfaces, so that the planes of the two positioning surfaces are in an intersecting relationship, and the intersecting line is located at one side close to the main housing 320, that is, the width of the second notch 314 gradually increases toward the direction of the second mounting surface 311. It is understood that such a design enables positioning under the limitation of the first positioning surface 315 and the second positioning surface 316 when the positioning block 121 is not sized to fit the third positioning slot 313 completely, thereby improving fault tolerance and replaceability.

Meanwhile, the length of the first positioning surface 315 in the axial direction of the connecting housing 310 is greater than the length of the second positioning surface 316 in the same direction, so that when the first positioning portion 120 rotates to the preset position, the positioning block 121 can be blocked by the first positioning surface 315 and can slide into the third positioning groove 313 under the guidance of the first positioning surface 315 to complete positioning, thereby effectively improving the installation efficiency.

As an improvement of the above solution, the positioning block 121 is provided with a third positioning surface 123 and a fourth positioning surface 124, a plane of the third positioning surface 123 and a plane of the fourth positioning surface 124 are opposite to the accommodating groove 113, when the first positioning portion 120 is located at the predetermined position, the third positioning surface 123 fits the first positioning surface 315, and the fourth positioning surface 124 fits the second positioning surface 316. It will be appreciated that such a design is effective in improving stability.

In some embodiments of the present invention, the connecting housing 310 further includes a guiding surface 317, the guiding surface 317 intersects with the second positioning surface 316 at an edge of the second notch 314, and the guiding surface 317 is used for guiding the first positioning portion 120 to move to the predetermined position.

Specifically, a guide surface 317 is further disposed on the connecting housing 310, the guide surface 317 is a plane and is disposed on a side of the second positioning surface 316 away from the first positioning surface 315, and the second positioning surface 316 and the guide surface 317 can meet at an edge of the second notch 314. At this time, the guide surface 317 is perpendicular to the arc-shaped side surface of the connecting housing 310, so that the positioning block 121 can abut against the guide surface 317 and slide on the guide surface 317 in the process that the first positioning portion 120 rotates to the preset position until the end surface of the positioning block 121 away from the bottom surface of the accommodating groove 113 abuts against the intersection between the second positioning surface 316 and the guide surface 317.

It will be appreciated that the design of the guide surfaces 317 is effective to improve the efficiency of installation.
