[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4As shown, the wheelbarrow handle height adjustment mechanism includes two mounting tubes 1, a grip rod 2 and a crossbeam 3. A plurality of insertion holes 4 are provided on both inner walls of the grip rod 2. The crossbeam 3 is provided with a fixing mechanism for fixing the grip rod 2. The fixing mechanism includes two insertion rods 5 slidably connected to the crossbeam 3. The upper end of the crossbeam 3 is fixedly connected to a mounting frame 8. The top of the mounting frame 8 is rotatably connected to a rotating shaft 7. The side wall of the rotating shaft 7 is fixedly connected to a gear 6. The side wall of the insertion rod 5 is provided with teeth meshing with the gear 6. Two sliding grooves are provided on the upper end of the crossbeam 3. The insertion rod 5 is slidably connected to the sliding groove to prevent the insertion rod 5 from moving left and right. The sliding groove is not shown in the figure. The side wall of the rotating shaft 7 is provided with a torsion spring 9.

[0023] A driving mechanism for driving the two insertion rods 5 to move is provided on the rotating shaft 7 . The driving mechanism includes a rotating rod 10 fixedly connected to the upper end of the rotating shaft 7 , and a rotating disk 11 is fixedly connected to the side wall of the rotating rod 10 .

[0024] In the present invention, a plurality of first hooks 13 are provided on the side wall of the crossbeam 3 , and the plurality of first hooks 13 are arranged at equal intervals, so that some bags can also be hung on the handle of the trolley, so that the trolley can carry more items.

[0025] In the present invention, a plurality of mounting holes 12 are provided on the side wall of the crossbeam 3 , and the mounting holes 12 are threadedly connected to the adjacent first hooks 13 , so that the first hooks 13 can be disassembled, and damaged first hooks 13 can be replaced separately.

[0026] In the present invention, the inner wall of the handle 2 is fixedly connected to a cross bar 14, and the side wall of the cross bar 14 is provided with a plurality of second hooks 16, so that there are more places for hanging bags on the handle, further improving the practicality of the device.

[0027] In the present invention, a plurality of fixing holes 15 are provided on the side wall of the crossbar 14 , and the fixing holes 15 are threadedly connected to the adjacent second hooks 16 , so that the second hooks 16 can be disassembled, and damaged second hooks 16 can be replaced separately.

[0028] It should be noted that the present invention is a wheelbarrow handle height adjustment mechanism. The user pulls one rod 5 together. When the rod moves out of the socket 4 of the grip 2, the rod 5 drives the other rod 5 to move through the gear 6, so that the other rod 5 is also away from the adjacent socket 4, and the grip 2 can be lifted or lowered. After releasing the rod 5, the gear 6 drives the two rods 5 to reset under the elastic action of the torsion spring 9. The handle height adjustment can be completed by only moving the rod 5 and releasing the rod 5, which greatly facilitates the adjustment of the handle height.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
