Figure 2 This is a schematic structural diagram of the first embodiment of the utility model from another angle. Figure 3 It is an overall cross-sectional view of the first embodiment of the utility model.

[0024] The present utility model provides a power output fork shaft, which includes a fork handle 101, a convex part 102, a cylinder 109, a telescopic rod 110 and a movable assembly 104. The movable member 108 includes a fork head 103, a driving gear 105, a driving rod 106, a driving motor 107, a connecting arm 117, a movable member 108, a protective member 111 and a contraction member 112. The movable member 108 includes a mounting seat 113, a connecting rod 114, a mounting ear 115 and a driving rack 116. Through the foregoing solution, the fork head 103 can be controlled to converge towards the middle, and the power output shafts with different diameters can be toggled, thereby improving the applicable range.

[0025] For this specific embodiment, it includes a fork handle 101, a convex part 102 and a fork head 103. The fork handle 101 is fixedly connected to the convex part 102 and is located on one side of the convex part 102. The specific structures and usage methods of the fork handle 101, the convex part 102 and the fork head 103 are recorded in the patent document with the publication number CN204279070U, which is not within the protection scope of this application and will not be elaborated here.

[0026] Among them, there are a movable member 108, a fork head 103, a driving motor 107, a driving rod 106, a driving gear 105, a driving rack 116 and a connecting arm 117. The movable member 108 is arranged on one side of the convex part 102, and the fork head 103 is arranged on one side of the convex part 102; the driving motor 107 is fixedly connected to the convex part 102 and is located on one side of the convex part 102. The driving rod 106 is fixedly connected to the output end of the driving motor 107 and is located on one side of the driving motor 107. The driving gear 105 is fixedly connected to the driving rod 106 and is located on one side of the driving rod 106. The driving rack 116 is slidably connected to the convex part 102 and meshes with the driving gear 105; the connecting arm 117 is rotatably connected to the driving rack 116 and is rotatably connected to the fork head 103 and is located between the driving rack 116 and the fork head 103. The output end of the driving motor 107 drives the driving rod 106 to rotate. The rotation of the driving rod 106 drives the driving gear 105 to rotate. When the driving gear 105 rotates forward and backward, one end of the driving rack 116 will be driven to move. Due to the movement of the driving rack 116, the other end will rotate on the connecting arm 117, thereby driving the movable member 108 to move. The movement of the movable member 108 drives the fork head 103. By adjusting the distance between the two fork heads 103, the power output shafts with different diameters can be toggled, thereby improving the applicable range.

[0027] Secondly, the telescopic rod 110 is slidably connected to the fork handle 101 and is located on one side of the fork handle 101. The cylinder 109 is fixedly connected to the telescopic rod 110 and is located on one side of the telescopic rod 110. The cylinder 109 is installed inside the telescopic rod 110. The output end of the cylinder 109 is fixedly connected to the fork handle 101. The output end of the cylinder 109 moves inside the telescopic rod 110, thereby driving the fork handle 101 to move and extending the control range of the fork head 103.

[0028] Meanwhile, the protective member 111 is fixedly connected to the fork head 103 and is located on one side of the fork head 103. The contraction member 112 is slidably connected to the protective member 111 and is located on one side of the protective member 111. When the fork head 103 moves, the protective member 111 protects the connection part and slides inside the contraction member, extends according to the angle of the fork head 103, and prevents the connection part from breaking so that the fork head 103 cannot be controlled to clamp.

[0029] In addition, the mounting seat 113 is fixedly connected to the convex portion 102 and is located on one side of the convex portion 102. The connecting rod 114 is fixedly connected to the mounting seat 113 and is located on one side of the mounting seat 113. The mounting ear 115 is rotatably connected to the connecting rod 114 and is located on one side of the connecting rod 114 and meshes with the driving gear 105. One side of the fork head 103 has the mounting ear 115. The connecting rod 114 passes through the mounting ear 115 and is fixed to the mounting seat 113. The fork head 103 can rotate with the connecting rod 114 as the origin. One end of the driving rack 116 is rotatably connected to the fork head 103, and the other end meshes with the driving gear 105. The output end of the driving motor 107 drives the driving rack 116 to move, thereby driving the angle of the fork head 103 and gathering the fork head 103 inward to clamp power output shafts with different diameters.

[0030] When using the present utility model, the output end of the driving motor 107 drives the driving rod 106 to rotate. The rotation of the driving rod 106 drives the driving gear 105 to rotate. When the driving gear 105 rotates forward and backward, it drives the driving rack 116 to move inside the convex portion. The movement of the driving rack 116 drives the fork head 103 to rotate on the connecting rod 114, thereby realizing the gathering of the fork head 103 towards the middle. After the fork head 103 gathers towards the middle, it can dial power output shafts with different diameters, improving the applicable range.

[0031] The second embodiment of this application is:

[0032] Based on the first embodiment, please refer to Figure 4 , wherein, Figure 4 is a schematic structural diagram of the whole of the second embodiment of the present utility model. A power output fork shaft provided by the present utility model further includes an anti-slip assembly 201. The anti-slip assembly 201 includes a column 202 and anti-slip lines 203.

[0033] For this specific embodiment, the column 202 is fixedly connected to the fork head 103 and is located on one side of the fork head 103. The anti-slip lines 203 are fixedly connected to the fork head 103 and are located on one side of the fork head 103. When the fork head 103 clamps an object, the column 202 will have limited contact with the power output shaft, and then the anti-slip lines 203 will increase the friction between the power output shaft and the column 202 to prevent the power output shaft from loosening during clamping.

[0034] When using the present utility model, the output end of the drive motor 107 drives the drive rod 106 to rotate. The rotation of the drive rod 106 drives the drive gear 105 to rotate. When the drive gear 105 rotates forward and backward, it drives the drive rack 116 to move in the protrusion. The movement of the drive rack 116 drives the fork head 103 to rotate on the connecting rod 114, so as to realize the gathering of the fork head 103 towards the middle. When the fork head 103 clamps the power output shaft, the column 202 will have limited contact with the object, and then the anti-slip lines 203 will increase the friction between the object and the column 202 to prevent the power output shaft from loosening during clamping.

[0035] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
