The sidewalls of the connecting bosses and connecting grooves are provided with through holes. One end of the two semi-enclosed bodies is hinged by a pin, and the other end is detachably hinged together as one piece by a fixing bolt.

[0004] The motor in this patent is the same as a conventional motor, with only one output shaft. Customers cannot achieve multi-axis rotation as needed. If a motor is required to drive two components to rotate, the corresponding function cannot be achieved. Utility Model Content

[0005] In view of the technical problem that the existing patented motors, like conventional motors, only have one output shaft, and customers cannot achieve multi-axis rotation as needed, and cannot achieve the corresponding function when one motor is required to drive two components to rotate, this utility model provides a motor with an adjustable output shaft.

[0006] The technical solution adopted by this utility model is as follows: a motor with an adjustable output shaft, including a motor body, a control box fixedly connected to the outside of the motor body, a first output shaft fixedly connected to the output end of the motor body, a drive rod rotatably connected inside the control box, sprockets fixedly connected to the outside of both the first output shaft and the drive rod, a chain sleeved on the outside of the sprockets, a positioning groove provided in the drive rod, a second output shaft passing through the control box, a rotating column fixedly connected to one end of the second output shaft, a limit rod fixedly connected to the outside of the rotating column, the limit rod slidably connected in the positioning groove, and an adjustment component for controlling the linear adjustment of the second output shaft provided outside the control box.

[0007] In one embodiment, the control box is provided with a bearing housing on its exterior, and the second output shaft is fixedly connected to a bearing inside the bearing housing.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, when the motor body drives the first output shaft to rotate, the limiting rod is engaged with the positioning groove, so that when the driving rod rotates, it can drive the second output shaft to rotate, realizing the synchronous rotation of the first output shaft and the second output shaft. If only the first output shaft needs to rotate, the second output shaft can be adjusted by adjusting the adjusting component so that the limiting rod is no longer engaged with the positioning groove, so that the second output shaft stops rotating, realizing that only the first output shaft rotates, which makes it convenient for users to select different output shafts according to their needs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0023] In order to solve the problems existing in the background art, this application proposes the following technical solution: a motor with an adjustable output shaft, including a motor body 1, a control box 2 fixedly connected to the outside of the motor body 1, and a first output shaft 3 fixedly connected to the output end of the motor body 1, which is used to drive the first output shaft 3 to rotate when the motor body 1 rotates.

[0024] In a further design, a drive rod 14 is rotatably connected inside the control box 2. A sprocket 12 is fixedly connected to both the first output shaft 3 and the outside of the drive rod 14. A chain 13 is sleeved on the outside of the sprocket 12. When the first output shaft 3 rotates, the drive rod 14 is driven to rotate through the cooperation of the sprocket 12 and the chain 13.

[0025] The drive rod 14 is provided with a positioning groove 15, and a second output shaft 4 is provided through the control box 2. One end of the second output shaft 4 is fixedly connected to a rotating column 16. A limit rod 17 is fixedly connected to the outside of the rotating column 16. The limit rod 17 is a cuboid structure, and the positioning groove 15 is a rectangular structure. Thus, when the positioning rod is engaged in the positioning groove 15, the drive rod 14 drives the second output shaft 4 to rotate.

[0026] In this embodiment, the limiting rod 17 is slidably connected to the positioning groove 15, and the outside of the control box 2 is provided with an adjustment component for controlling the second output shaft 4 to perform linear adjustment.

[0027] In another design, a bearing seat 5 is provided on the outside of the control box 2. The second output shaft 4 is fixedly connected to the bearing inside the bearing seat 5. An adjustment bracket 6 is fixedly connected to the outside of the bearing seat 5. A fixed seat 8 and a fixed plate 11 are fixedly connected to the outside of the control box 2. The bearing seat 5 is used to support and adjust the second output shaft 4.

[0028] In the specific design, the adjustment components include a threaded rod 7 rotatably connected between the fixed base 8 and the fixed plate 11, and a guide rod 10 fixedly connected to the outside of the fixed plate 11. The guide rod 10 passes through the movable frame and is fixedly connected to the fixed base 8. The threaded rod 7 is threadedly connected to the movable frame. A handwheel is fixedly connected to the outside of the threaded rod 7. When the first output shaft 3 rotates, the threaded rod 7 is rotated to drive the movable frame to move linearly. The movable frame drives the bearing seat 5 to move. The bearing seat 5 drives the second output shaft 4 to slide outward, so that the limit rod 17 is no longer stuck with the positioning groove 15. At the same time, the positioning bolt 9 is rotated to abut and fix the threaded rod 7, thereby fixing the movable frame. Therefore, when the first output shaft 3 drives the drive rod 14 to rotate, it will not drive the second output shaft 4 to rotate. Only the first output shaft 3 can rotate.

[0029] In addition, a threaded hole is provided through the movable frame, and a positioning bolt 9 is threadedly connected in the threaded hole. The positioning bolt 9 abuts against the threaded rod 7 to fix the movable frame and prevent it from shifting.

[0030] To ensure that those skilled in the art can fully understand the technical solution, the usage process of this embodiment is as follows:

[0031] In the initial state, the limit rod 17 is engaged in the positioning groove 15. The start motor body 1 drives the first output shaft 3 to rotate. The first output shaft 3 drives the drive rod 14 to rotate through the cooperation of the sprocket 12 and the chain 13. The drive rod 14 drives the second output shaft 4 to rotate. The second output shaft 4 rotates stably through the bearing seat 5, thereby realizing that one motor body 1 drives two output shafts to rotate.

[0032] When only the first output shaft 3 needs to rotate, simply rotate the threaded rod 7 to drive the moving frame to move linearly. The moving frame drives the bearing seat 5 to move. The bearing seat 5 drives the second output shaft 4 to slide outward, so that the limit rod 17 is no longer stuck with the positioning groove 15. At the same time, rotate the positioning bolt 9 to abut and fix the threaded rod 7, thereby fixing the moving frame.

[0033] Therefore, when the first output shaft 3 drives the drive rod 14 to rotate, it will not drive the second output shaft 4 to rotate. Only the first output shaft 3 can rotate. If the second output shaft 4 needs to rotate again, the threaded rod 7 can be rotated again to make the moving frame drive the limiting rod 17 outside the second output rod to engage in the positioning groove 15. Then, when the drive rod 14 rotates, the second output shaft 4 can be driven to rotate, thereby realizing the adjustment of the output shaft.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
