Background
Industrial joysticks have found use in a variety of mechanical devices and applications include: industrial control, remote radio control, radar navigation systems, robotics, measurement systems, heavy machinery, mobile machinery. When the industrial operating lever is operated, a spring return method is mainly adopted. After the operator releases his hand, the handle is quickly returned to the upright position (center position) by the built-in spring or rubber positioning member. In the existing operating lever based on the spring return principle, a spring is additionally arranged on the shaft body part of the operating lever. The spring can quickly push the operating lever back to the central position after an operator releases his hand, and the operating lever is guided to achieve the purpose of resetting. However, the resetting method has the following disadvantages in use, that is, 1, in a scene needing slow resetting, an operator cannot directly release hands and needs to always operate the guide resetting. High requirements are put on the quality and the operation process of operators. And the potential danger of runaway easily exists, such as sudden incapability of an operator or loss of control over the operating lever, that is, slow reset cannot be realized according to requirements. 2. The handle resets suddenly under the spring action, probably causes the signal sudden change, and can continue to have slight shake process after resetting, influences electric signal and judges. 3. After a long time of use, the stress of the spring may be changed, resulting in failure to achieve accurate restoration.

Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It is to be noted that, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example 1, as shown in fig. 1, an industrial joystick based on gravity effect and damping grease comprises a dust cover 1 and a dust cover fixing ring, wherein the dust cover is fixed at the upper part of an upper sealed cavity through the dust cover fixing ring. 1 upside of dust cover be provided with handle 2, handle 2 is including rubber sleeve and handle body 3, in the upper end of handle body 3 was inlayed into the rubber sleeve, can improve the comfort level of handle. The lower part of the handle 2 is provided with a transverse X rotating shaft and a longitudinal Y rotating shaft, wherein the Y rotating shaft 4 is connected with the lower part of the handle body, the X rotating shaft 5 transversely passes through the Y rotating shaft, and the X rotating shaft is in linkage connection with the Y rotating shaft. The whole handle body has X, Y two degrees of freedom. The lower end of the Y-shaped rotating shaft 4 is provided with a gravity ball 11 for slowly resetting the handle, the gravity ball is spherical and is embedded at the lower end of the Y-shaped rotating shaft. The handle can be slowly reset by the gravity ball. The lower extreme of Y rotation axis is set up to the mode that the gravity ball was inlayed, and this mode can realize reforming transform the lower extreme of current Y rotation axis and install the gravity ball.
