[0026] In one embodiment of the present invention, Figure 1-5 As shown, a virtual simulation control handle comprises a base 1, a fixed cylinder 6 arranged on the base 1, a movable cylinder 7 slidably arranged on the outer circumferential surface of the fixed cylinder 6, and a hand-held cylinder 8 rotatably arranged at one end of the movable cylinder 7, wherein the fixed cylinder 6, the movable cylinder 7, and the hand-held cylinder 8 are all hollow, a pressing portion 9 is movably penetrated on one side of the movable cylinder 7, a first connecting rod 10 is fixedly arranged at one end of the pressing portion 9 extending into the interior of the movable cylinder 7, one end of the first connecting rod 10 is connected to the inner wall of the movable cylinder 7 by a spring 12, and a vertical connecting rod 10 is fixedly arranged below the first connecting rod 10 A second connecting rod 13 is provided, one end of the second connecting rod 13 extends into the fixed tube 6, a plurality of first clamping blocks 17 arranged vertically and equidistantly are fixedly provided on the inner wall of the fixed tube 6, one end of the second connecting rod 18 extending into the fixed tube 6 is fixed with a second clamping block 18, a slot for inserting the second clamping block 18 is reserved between two adjacent first clamping blocks 17, an arc groove 19 is provided on the inner wall of the hand-held tube 8, one end of the pressing portion 9 away from the first connecting rod 10 is slidably provided in the arc groove 19, and the width of the arc groove 19 decreases or increases along the rotation direction of the hand-held tube 8;

[0027] See also Figure 2 , 3, 4, 5. Specifically, the fixed cylinder 6 is arranged on the base, and the movable cylinder 7 is slidably arranged on the outer circumferential surface of the fixed cylinder 6. The hand-held cylinder 8 is sleeved on the end of the movable cylinder 7 away from the fixed cylinder 6, and the hand-held cylinder 8 can rotate at one end of the movable cylinder 7, but there will be no vertical displacement. A movably penetrating pressing portion 9 is provided on the outer wall of the movable cylinder 7. One end of the pressing portion 9 extends out of the movable cylinder 7, and the other end extends into the interior of the movable cylinder 7. The end of the pressing portion 9 extending out of the movable cylinder 7 is slidably arranged in the arc groove 19. The arc groove 19 is arranged on the inner wall of the hand-held cylinder 8, and one side of the arc groove 19 is connected with the internal hollow position of the hand-held cylinder 8, and along the rotation direction of the hand-held cylinder 8, the width of the arc groove 19 decreases or increases. Since the hand-held cylinder 8 can be rotated clockwise or counterclockwise, regardless of the rotation direction of the hand-held cylinder 8, as long as the width of the arc groove 19 in this application is increasing or decreasing, It can be ensured that when the hand-held cylinder 8 is rotated, the pressing portion 9 can be driven to move toward or away from one side of the spring 12, thereby realizing the clamping and separation between the second clamping block 18 and the first clamping block 17. In the initial state, the second clamping block 18 is inserted between the two adjacent first clamping blocks 17. At this time, the movable cylinder 7 and the fixed cylinder 6 are in a fixed state and cannot be adjusted. When adjustment is required, the hand-held cylinder 8 is rotated along the direction of decreasing width of the arc groove 19 or along the direction opposite to the increasing width of the arc groove 19. After the rotation, the pressing portion 9 moves toward one side of the spring 12, thereby driving the second clamping block 18 to disengage from the first clamping block 17, and then the hand-held portion 8 is pulled to adjust the position of the movable cylinder 7 on the fixed cylinder 6. Then, the hand-held portion 8 is rotated in the opposite direction. Under the action of the spring, the pressing portion 9 and the second clamping block 18 are reset and inserted between the two adjacent first clamping blocks 17. At this time, the fixed cylinder 6 and the movable cylinder 7 are in a fixed state;

[0028] like Figure 3 , 5 As shown, it should be noted that one end of the pressing portion 9 is arranged in the arc groove 19, and a certain thickness is still left between the end of the arc groove 19 with the smallest width and the inner wall of the hand-held tube 8, so the pressing portion 9 can only slide in the arc groove 19, and under the limiting effect of the arc groove 19, the pressing portion 9 will not be separated from the arc groove 19. At the same time, through the matching between the pressing portion 9 and the arc groove 19, the displacement between the hand-held portion 8 and the movable tube 7 can be avoided, and the stability during the adjustment process can be ensured. At the same time, the pressing portion 9 is covered by the hand-held tube 8, so that the pressing portion 9 will not be exposed to the outside, thereby avoiding the situation where the pressing portion 9 is accidentally touched.

[0029] In this embodiment, a mounting plate 2 is fixedly provided below the base 1, and a plurality of mounting holes are provided on the mounting plate 2;

[0030] Specifically, the control handle can be installed on the corresponding virtual simulation device through the installation plate 2 to perform the mining simulation process.

[0031] In this embodiment, the base 1 is provided with a concave mounting groove, a spherical sleeve 3 is hingedly provided in the mounting groove, the spherical sleeve 3 is hollow and has an arc-shaped opening, a connecting ball head 5 is movably provided in the spherical sleeve 3, and one end of the fixed cylinder 6 away from the movable cylinder 7 is fixedly connected to the connecting ball head 5;

[0032] Specifically, the spherical kit 3 itself is a spherical structure larger than a hemisphere, and the connecting ball head 5 is arranged in the spherical kit 3 to avoid separation and falling off. At the same time, by swinging the hand-held tube 8, and then through the connection between the connecting ball head 5 and the spherical kit 3, movement in multiple degrees of freedom can be achieved.

[0033] In this embodiment, the base 1 is provided with a plurality of movable grooves 4 for the spherical sleeve 3 to move, and a plurality of the movable grooves 4 are connected to the mounting grooves;

[0034] Specifically, in this embodiment, the movable slot 4 is a cross-shaped structure, so the corresponding control handle can swing in four degrees of freedom.

[0035] In this embodiment, a fixing plate 11 is fixedly disposed at one end of the first connecting rod 10 away from the pressing portion 9, and one side of the fixing plate 11 is connected to the inner wall of the movable cylinder 7 through the spring 12;

[0036] Specifically, since the first connecting rod 10 itself is a slender rod, by providing a fixing plate 11 having a size larger than the cross section of the first connecting rod 10 and connecting the fixing plate 11 to the spring 12, the smoothness of the resetting of the pressing portion 9 can be improved.

[0037] In this embodiment, a limit plate 14 is provided below the first connecting rod 10, and the limit plate 14 is fixed on the inner wall of the movable cylinder 7. The second connecting rod 13 movably passes through the limit plate 14, and the limit plate 14 is provided with a running groove for the second connecting rod 13 to move.

[0038] Specifically, the limiting plate 14 can be used to limit the adjustment position between the movable cylinder 7 and the fixed cylinder 6 , while the running groove facilitates the movement of the second connecting rod 13 .

[0039] In this embodiment, a plurality of sliders 16 are fixedly disposed on the outer wall of the fixed cylinder 6, and a plurality of slide grooves 15 corresponding to and matching the sliders 16 are disposed on the inner wall of the movable cylinder 7;

[0040] Specifically, the slider 16 cooperates with the slide groove 15 to facilitate the sliding of the movable cylinder 7 on the fixed cylinder 6 on the one hand, and to limit the rotation between the movable cylinder 7 and the fixed cylinder 6 on the other hand.

[0041] In this embodiment, an anti-slip groove 20 is provided on the outer wall of the hand-held tube 8;

[0042] Specifically, the anti-slip groove 20 matches the shape of a human hand to prevent the human hand from being loosened from the hand-held tube 8 .

[0043] In summary, in the virtual simulation control handle in the above embodiment of the utility model, in the initial state, the second card block 18 is clamped between the two adjacent first card blocks 17. At this time, under the action of the first card block 17 and the second card block 18, the fixed cylinder 6 and the movable cylinder 7 are in a fixed state and cannot be adjusted. When adjustment is required, by rotating the hand-held portion 8, the pressing portion 9 can be squeezed while rotating the hand-held portion 8 under the action of the arc groove 19, thereby driving the first connecting rod 10 and the second connecting rod 13 to run, so that the second card block 18 is separated from the first card block 17. At this time, after freely pulling the hand-held portion 8 and adjusting it to an appropriate height, the hand-held portion 8 is rotated in the opposite direction. Under the action of the elastic force of the spring 12, the pressing portion 9 is reset and the second card block 18 is clamped between the two adjacent first card blocks 17, so as to achieve locking between the fixed cylinder 6 and the movable cylinder 7. At the same time, the above operation can realize the adjustment of the control handle, reduce the difficulty of adjustment and improve the efficiency of excavation simulation. The adjustment operation is simple and the pressing portion 9 is not prone to accidental touch.
