Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0025] A multifunctional control handle, such as Figure 1-Figure 3 As shown, it includes a fixed base 1 and a control component 2 arranged on the fixed base 1, the control component 2 includes a fixed handle 3, a connecting rod 4 and a friction head 5, the bottom end of the fixed handle 3 is fixedly connected to the connecting rod 4, the bottom end of the fixed base 1 is provided with a friction baffle 11, the friction head 5 is sleeved on the friction baffle 11 and protrudes from the fixed base 1, one end of the connecting rod 4 passes through the fixed base 1 and penetrates into the friction head 5, a spherical portion 41 is integrally connected on the connecting rod 4 and located in the fixed base 1, a damping ball holder 12 is symmetrically provided in the fixed base 1 and located at the upper and lower ends of the spherical portion 41, and the end of the friction head 5 protruding from the fixed base 1 is flat.

[0026] During the application of the multifunctional control handle, it includes a moving part 100 and a fixed part 200. The fixed seat 1 is arranged on the moving part 100. The friction head 5 protrudes from one end of the fixed seat 1 and abuts against the fixed part 200. The friction head 5 and the fixed part 200 maintain planar friction.

[0027] During the specific implementation process, the control component 2 uses the spherical part 41 as the support position on the fixed seat 1 and drives the connecting rod 4 by applying external force to the fixed handle 3, thereby maintaining the movement of the friction head 5 relative to the fixed part 200, and has completed the preliminary position adjustment of the four degrees of freedom of the moving part 100 connected to the control handle in the front, back, left and right directions. There is planar friction between the friction head 5 and the fixed part 200, and the friction head 5 has a moving space in the fixed seat 1. Therefore, when it is necessary to fine-tune the position of the moving part 100 or the external receiving device, it is only necessary to slightly swing the fixed handle 3 in the corresponding direction to drive the moving part 100 or the receiving device in the product to achieve fine-tuning of the spatial position. Under the cooperation of the damping ball holder 12, the spherical part 41 contacts the damping ball holder 12 and produces a damping effect, so as to keep the operating feel of the control handle comfortable and improve practicality.

[0028] Furthermore, the control assembly 2 includes an encoder 6, a screw cap 7, a button 8 and a button plate 9. The encoder 6 is arranged in the fixed handle 3, the button 8 is arranged at the top of the fixed handle 3, the screw cap 7 is sleeved on the fixed handle 3 and the button 8, and the button 8 protrudes from the screw cap 7. The screw cap 7 is transferred to the fixed handle 3, and the inner wall of the button 8 matches the inner wall of the screw cap 7. One end of the encoder 6 is transferred to a connecting shaft 61 that penetrates into the button 8 and is interference-connected with the button 8. An elastic member 62 and a button plate 9 are sleeved on the connecting shaft 61. The two ends of the elastic member 62 are respectively in contact with the encoder 6 and the button 8. That is, through this arrangement, the user rotates the screw cap 7. And it drives the connecting shaft 61 to rotate, thereby making the encoder 6 work and send a signal to the driving device connected to it. For example, the encoder 6 outputs a signal to the external motor and the external motor drives the moving part 100 or the receiving device to move up and down. In this way, the spatial position of the moving part 100 in the product in the up and down degrees of freedom can be accurately adjusted. On this basis, after the spatial position of the moving part 100 in the product is accurately positioned, the button 8 can be pressed to the key panel 9 to prompt the key panel 9 to conduct the action signal and complete subsequent functional actions such as collecting information. The button 8 is reset under the deformation of the elastic part 62.

[0029] It should be noted that the fixed handle 3 is designed as a stepped cylindrical structure with a hollow interior. From top to bottom, the fixed handle 3 includes an integrally connected connecting portion 31, an extension portion 32, a reduction portion 33 and an extension portion 34. The reduction portion 33 is designed as a frustum with a gradually decreasing outer diameter, so as to improve the overall structural smoothness and stability of the fixed handle 3, facilitate gripping and operation, and the extension portion 34 is fixed to the connecting rod 4 by a threaded connection to keep the fixed handle 3 and the connecting rod 4 stably connected.

[0030] Furthermore, the screw cap 7 has an inverted U-shaped structure and matches the connecting portion 31. The connecting portion 31 is provided with an annular groove 311. A matching screw 71 is provided on the inner wall of the screw cap 7 corresponding to the annular groove 311. The matching screw 71 matches the annular groove 311 and is used to connect the screw cap 7 and the connecting portion 31 and constrain each other to facilitate the rotation of the screw cap 7 relative to the fixed handle 3.

[0031] A soft protective cover 72 is provided on the outer surface of the screw cap 7 to improve the operating feel.

[0032] During the specific implementation process, a wiring hole 42 is opened on one side of the spherical part 41, and a signal line 63 is provided at one end of the encoder 6. The signal line 63 passes through the fixed handle 3 and the connecting rod 4 in sequence, and is led out through the wiring hole 42 and electrically connected to the external equipment.

[0033] Furthermore, a slot 43 is provided on one side of the spherical portion 41, and a limit pin 13 is provided in the fixing seat 1 at a position corresponding to the slot 43. The limit pin 13 abuts against or maintains a distance from the slot 43 to limit the clockwise and counterclockwise rotation of the connecting rod 4 and improve the stability of the structural connection.

[0034] Among them, a gasket 14 is provided in the fixed base 1 and at one end of the friction head 5. The gasket 14 and the friction baffle 11 clamp the friction head 5 and are movably connected to the fixed base 1. That is, through this arrangement, the friction head 5 has a movable space in the fixed base 1, which facilitates fine-tuning of the spatial position of the moving part 100 or the receiving device.

[0035] Furthermore, a compression ring nut 15 is provided in the fixing seat 1 and at one end of the damping ball holder 12 . The compression ring nut 15 abuts against the fixing seat 1 and the damping ball holder 12 respectively, so as to keep the damping ball holder 12 and the spherical portion 41 tightly fitted.

[0036] A dust cover 16 is provided on the top of the fixing base 1 , and the dust cover 16 is sleeved on the extension portion 34 to improve the practicality of the device.

[0037] To sum up, the present invention has the following beneficial effects: the present invention discloses a multifunctional control handle, comprising a fixed base 1 and a control assembly 2 arranged on the fixed base 1, the control assembly 2 comprises a fixed handle 3, a connecting rod 4 and a friction head 5, the bottom end of the fixed handle 3 is fixedly connected to the connecting rod 4, the bottom end of the fixed base 1 is provided with a friction baffle 11, the friction head 5 is sleeved on the friction baffle 11 and protrudes from the fixed base 1, one end of the connecting rod 4 passes through the fixed base 1 and penetrates into the friction head 5, a spherical portion 41 is integrally connected on the connecting rod 4 and located in the fixed base 1, a damping ball holder 12 is symmetrically provided in the fixed base 1 and located at the upper and lower ends of the spherical portion 41, and abuts against the spherical portion 41, and the end of the friction head 5 protruding from the fixed base 1 is flat. That is, through this setting, the control accuracy, control angle and control space of the control handle are improved, the efficiency is high and the control is comfortable, and the large-scale rapid movement and small-scale fine-tuning of the spatial position of the moving part 100 in the product in the four degrees of freedom directions of front, back, left and right, as well as other functions such as precise adjustment of the spatial position in the two degrees of freedom directions of up and down and information collection are realized. The adjustment of the spatial position of the moving part 100 in the product has significant advantages such as short adjustment time, high efficiency, easy to use, and comfortable operating experience.
