[0002] Electric tricycles, as a common short-distance means of transportation, have been widely used in urban and rural areas due to their economic practicality and strong cargo capacity. In the production and assembly process of electric tricycles, the assembly of the handlebars is a crucial step, as the installation precision and stability of the handlebars directly affect the driving safety and handling of the electric tricycle.

[0003] Currently, existing clamps are often designed for specific handlebar models, resulting in poor versatility. When dealing with handlebars of different diameters or shapes, clamp components need to be frequently replaced, making the operation cumbersome and severely restricting the assembly line's pace. The repeated tightening of screws also greatly increases the labor intensity of operators. Furthermore, existing fixing devices are fixed to the table at a fixed height, which requires operators to maintain the same height posture for extended periods, easily leading to lower back fatigue and occupational injuries. The fixed working height cannot accommodate operators of different heights and is difficult to flexibly address the changes in installation height caused by different frame specifications, further affecting the comfort and universality of the installation operation.

The crossbar 32 makes the entire device a whole. The crossbar 32 and the slider 26 are connected through and slidably, which allows the slider 26 to slide on the crossbar 32 without detaching from it. Multiple slots 37 are provided on the left side of the left support rod 31. 7. In conjunction with ratchet 33 and irregular positioning rod 35, the entire unit is raised and lowered. The ratchet 33 is engaged inside the slot 37. The rotation of the ratchet 33 causes the connected support rod 31 to move up and down. A first positioning rod 332 is rotatably connected through the ratchet 33. The first positioning rod 332 is the central axis of the ratchet 33's rotation. An auxiliary rod 331 is fixedly connected to the left side of the ratchet 33. The auxiliary rod 331 facilitates the operator to rotate the ratchet 33 appropriately. An irregular positioning rod 35 is engaged inside the lower slot 37. The irregular positioning rod 35 fixes a certain height. The irregular positioning rod 35 is a multi-segment folded rod. A second positioning rod 351 is rotatably connected through the irregular positioning rod 35. The second positioning rod 351 is the rotation center of the irregular positioning rod 35. A spring 352 is fixedly connected to the lower left side of the irregular positioning rod 35. The spring 352 provides downward pressure space for the irregular positioning rod 35.

[0019] A housing 36 is provided on the outside of the support rod 31. The housing 36 prevents the ratchet 33 from detaching from the support rod 31. A first mounting slot 361 is provided on the left side of the housing 36, allowing the auxiliary rod 331 to move. A second mounting slot 362 is provided on the left side of the housing 36, providing space for the irregularly shaped positioning rod 35 to move. A base 38 is fixedly connected to the lower part of the housing 36. The base 38 is designed to facilitate the installation of the entire device on a table. The auxiliary rod 331 passes through and is movably connected to the first mounting slot 361, and the irregularly shaped positioning rod 35 passes through and is movably connected to the second mounting slot 362. The lower part of the spring 352 is fixedly connected to the base 38 to prevent spring from bouncing. Spring 352 is disengaged from the installation. Positioning rod 351 is rotatably connected to the inner wall of housing 36. Positioning rod 332 is fixedly connected to the inner wall of housing 36. Support seat 39 is slidably connected to the lower part of right support rod 31. Support seat 39 allows support rod 31 to slide in a certain direction. The lower part of support seat 39 is fixedly connected to base 38. The upper part of support rod 31 is fixedly connected to the lower part of support block 23. Knob 241 is fixedly connected to the right side of bidirectional threaded rod 24. Knob 241 facilitates the operator to rotate bidirectional threaded rod 24. Connecting rod 12 is fixedly connected to the rear of handlebar 1. Connecting rod 12 connects mounting rod 11 and handlebar 1. The rear of connecting rod 12 is fixedly connected to the outer wall of mounting rod 11.

[0020] Working principle: The operator first places the handlebar 1 to be assembled into the V-groove 231 of the two support blocks 23. The buffer pad 22 in the groove increases friction and provides protection. The sliding retaining ring 25 is moved to the appropriate position and the mounting rod 11 is inserted into the retaining ring 25. Then, the operator rotates the knob 241 on the right side of the double-threaded rod 24 clockwise. The rotation of the double-threaded rod 24 drives the two moving plates 21 on it to move synchronously and close to each other along the sliding groove 232 on the support block 23. As the moving plates 21 continue to move closer, their inner sides eventually contact the upper part of the handlebar 1 and apply a uniform clamping force, thereby stably clamping the handlebar 1 into the limiting space formed by the V-groove 231 and the moving plates 21, completing the quick fixation. This process utilizes the self-locking characteristic of the screw drive to ensure the reliability of the clamping state. Rotating the knob 241 in the opposite direction will drive the two moving plates 21 away from each other, quickly releasing the handlebar. When adjustment is needed... When adjusting the handlebar height, the operator first presses down on the left end of the shaped positioning rod 35, causing its lower end to overcome the elastic force of the spring 352 and disengage from the slot 37 on the support rod 31, thus releasing the height lock. Then, the operator pulls down on the auxiliary rod 331 of the ratchet 33, driving the ratchet 33 to rotate. Since the ratchet 33 engages with the slot 37 on the support rod 31, the rotation of the ratchet 33 will push the support rod 31, causing it, along with the entire fixing assembly 2 and the clamped handlebar, to rise smoothly upwards. When the height is adjusted to the appropriate position, the operator releases the shaped positioning rod 35, which automatically swings downwards under the restoring force of the spring 352 and re-locks into the slot 37 at the current height, achieving self-locking and preventing the support rod 31 from sliding down. This completes a safe and effortless height adjustment. When lowering is required, the operator must press down on the left side of the shaped positioning rod 35 again, and then apply external pressure to lower the support rod 31 to the target slot 37 position before locking it again.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
