[0034] The linear module includes a linear motor 1, and the rotary module includes a rotary motor 2;

[0035] The linear motor mover of the linear motor 1 is connected to the connecting member 3, and the connecting member 3 is connected to the rotary motor 2;

[0036] When the linear motor 1 is working, the linear motor mover drives the connecting member 3 to move linearly, and the connecting member 3 drives the rotary motor 2 to move linearly, and the rotary motor shaft 21 of the rotary motor 2 serves as the output shaft of the linear rotary motor.

[0037] The linear rotary motor provided in the embodiment of the present application is connected to the rotary motor only by a connecting piece, and the rotary motor shaft directly serves as the output shaft of the linear rotary motor. Compared with the linear rotary motor in the prior art, fewer components are used to achieve connection and output of driving force, thereby reducing complex mechanical connections and reducing structural complexity.

[0038] In the embodiment of the present application, the rotating motor 2 can be connected to the connecting member 3 through the rotating motor fixing member 22.

[0039] In one embodiment of the present application, Figure 1-Figure 3 As shown, the linear rotary motor may further include: a linear guide rail 4 and a slider (not shown in the figure);

[0040] The connecting member 3 is fixedly mounted on the slide block and can be driven by the linear motor mover to move linearly along the linear guide rail 4 .

[0042] Further, in one embodiment of the present application, Figure 1-Figure 3 As shown, the linear module may further include: a linear encoder 5;

The initial position of the magnetic spring mover 61 can be called the spring initial position.

[0057] The baffle 9 is connected to the magnetic spring mover 61 , and when the magnetic spring mover 61 moves to the initial position of the baffle, it blocks the photosensitive element of the photoelectric switch 8 , so that the photoelectric switch 8 triggers the position data of the rotating motor 2 to return to zero.

[0058] In the embodiment of the present application, the photoelectric switch 8 can be directly mounted on the housing of the linear rotary motor, or can be mounted on the housing through a photoelectric switch fixing member.

[0059] In one embodiment of the present application, Figure 1-Figure 3 As shown, the rotating module further includes: an air pipe 10 connected to the rotating motor shaft 21 of the rotating motor 2;
