[0025] Reference Figure 1-5 Now, a fork assembly provided by an embodiment of the utility model is described. A fork assembly includes an aluminum alloy body 1, characterized in that: a bushing 2 is slidably installed inside the aluminum alloy body 1, a fork mouth frame 3 is die-cast on the outer wall of the aluminum alloy body 1, a shift block 4 is die-cast on the outer wall of the aluminum alloy body 1 and at the bottom of the fork mouth frame 3, a fixing component for fixing the bushing 2 is installed inside the aluminum alloy body 1, and a fixing ring 6 for driving the fixing component is movably installed on the outer wall of the aluminum alloy body 1.

[0026] First, install the bushing 2 inside the aluminum alloy body 1, then rotate the fixing ring 6 so that the fixing assembly fixes the bushing 2 inside the aluminum alloy body 1, and then it can be used. When in use, move the device position through the shift block 4, and then move the gear inside the gearbox through the fork frame 3.

[0027] The fixing assembly includes an installation groove 5, a sliding groove 501, a clamping block 502 and a push rod 503. The inner wall of the aluminum alloy body 1 is provided with two symmetrically distributed installation grooves 5. The sliding groove 501 is provided at one end of the installation groove 5. The clamping block 502 is internally slidably installed in the installation groove 5. The push rod 503 is fixedly connected to one end of the clamping block 502. When in use, the push rod 503 is pushed forward by the push ring 601, and at the same time, the clamping block 502 is driven forward to clamp the bushing 2 out.

[0028] The outer wall of the block 502 is fixedly connected to two symmetrically distributed springs 8, and one end of the spring 8 away from the block 502 is fixed to the inner wall of the mounting groove 5. When the bushing 2 needs to be loosened, the block 502 is no longer supported by the push ring 601 and is pulled by the spring 8, so that the block 502 enters the interior of the aluminum alloy body 1, and the bushing 2 can be taken out.

[0029] The inner wall of the fixing ring 6 is fixedly connected with a push ring 601 corresponding to the push rod 503, the outer wall of the aluminum alloy body 1 is provided with a movable groove 602 for installing the push ring 601, the outer wall of the aluminum alloy body 1 and the interior of the fixing ring 6 are provided with threads 603, and the inner wall of the fixing ring 6 is fixedly connected with a protrusion 604 for pushing the push rod 503. When in use, the fixing ring 6 is rotated, which drives the push ring 601 to rotate, and the protrusion 604 on the inner wall of the push ring 601 drives the push rod 503 forward, so that the bushing 2 can be fixed.

[0030] The outer wall of the fixing ring 6 is provided with a plurality of anti-skid patterns 7 distributed in an annular shape. When the fixing ring 6 is rotated, the anti-skid patterns 7 allow the fixing ring 6 to be better gripped during use and prevent slipping during rotation.

[0031] The outer wall of the fork frame 3 is provided with two symmetrically distributed slots 301. When in use, the slots 301 are stuck in the gears inside the gearbox, so that the gears can be shifted better when shifting.

[0032] Working principle: First, slide the bushing 2 and install it inside the aluminum alloy body 1, then rotate the fixing ring 6. When the fixing ring 6 rotates, it drives the push ring 601 to rotate, and pushes the push rod 503 forward through the protrusion 604 on the inner wall of the push ring 601, and drives the clamping block 502 forward at the same time to clamp the bushing 2 out, so that the bushing 2 can be fixed inside the aluminum alloy body 1 for use. When in use, move the device position through the shifting block 4, and then shift the gear inside the gearbox through the fork frame 3. When the bushing 2 needs to be removed, rotate the fixing ring 6 to drive the push ring 601 to move its position. At this time, the clamping block 502 is no longer supported by the push ring 601, and is pulled by the spring 8, so that the clamping block 502 enters the interior of the aluminum alloy body 1, and the bushing 2 can be taken out.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
