For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Examples, such as Figures 1-6As shown, this utility model provides an adjustable height bracket for a garden tool trailer, including a hanging beam 1. The hanging beam 1 has a group of hanging holes, and a vertical square tube 2 arranged in a T-shape in the middle of the hanging beam 1. A connecting seat 3 is provided at the bottom of the vertical square tube 2. The number of hanging holes in the hanging hole group, along with the shape and relative position of the holes, can be customized according to the characteristics of the actual garden tool's mounting end. To improve the utilization rate of this bracket, the vertical square tube 2 provided by this utility model is provided with a clamping plate 4 on its side. The clamping plate 4 includes a U-shaped section 41 and a vertical plate section 42 provided at the end of the U-shaped section 41. A clamping bolt 5 is provided on the vertical plate section 42. The clamping bolt 5 is used to connect the clamping plate 4 to the trailer side 6. The vertical square tube 2 is provided with a plurality of vertically spaced first adjustment holes 21. A claw part 7 is provided in the first adjustment hole 21. A first positioning bolt 8 is provided near the bottom of the vertical square tube 2. The side of the connecting seat 3 is provided with a plurality of vertically spaced second adjustment holes 31 that cooperate with the first positioning bolt 8. A plurality of second positioning bolts 9 for connecting with the trailer are provided on the connecting seat 3. A pre-tightening component 10 is provided inside the vertical square tube 2. The pre-tightening component 10 includes a pre-tightening seat 101 that cooperates with the first positioning bolt 8. A pre-tightening spring 102 is provided between the pre-tightening seat 101 and the connecting seat 3.

[0024] Specifically, the clamp plate 4 is used to limit the horizontal position of the vertical square tube 2 and establish an installation relationship with the trailer side. Regarding the height of the vertical square tube 2, by adjusting the connection between the first positioning bolt 8 and the second adjustment hole 31 at different positions on the connecting seat 3, the combined height of the vertical square tube 2 and the connecting seat 3 can be adjusted, thereby adjusting the overall height of the hanging beam 1. Furthermore, the pre-tightening component 10 between the connecting seat 3 and the vertical square tube 2 can improve the pre-tightening performance of the first positioning bolt 8 and enhance the connection reliability between the first positioning bolt 8 and the second adjustment hole 31. Further, the vertical square tube 2 provides different height installation nodes for the claw component 7, namely the first adjustment hole 21. This allows the claw component 7 to be installed at different positions. The claw component 7 can be used to clamp the square tube or round rod of the suspended tool, and then the square tube and round rod can suspend some relatively short garden tools, thereby improving the overall utilization rate of this bracket on the garden trailer.

[0025] To improve the quick clamping performance of the jaws on square tubes and round rods, the jaw component 7 provided by this utility model includes four jaw teeth 71 distributed in an X-shape. The jaw teeth 71 have an L-shaped structure with an acute angle at the opening of the L-shape, and the tips of the jaw teeth 71 face the central symmetrical point of the four teeth. The jaw teeth 71 are mounted on a backing plate 72, and a screw 73 that mates with the first adjustment hole 21 is provided on the backing plate 72. A locking nut 74 is provided on the screw 73. The distance between the tips of the four jaw teeth 71 is less than the maximum diameter of the independent square tube and independent round rod carried by the trailer. The square tube and round rod can be compressed to open the clamping opening 1014 of the four jaw teeth 71 until the square tube / round rod falls at the root of the jaw teeth 71, thereby achieving the purpose of quick clamping. The screw 73 behind the backing plate 72 is used to mate with the first adjustment hole 21 at different height positions and is locked by the locking nut 74, thereby achieving the purpose of adjusting the actual height of the square tube and round rod.

[0026] To improve the pre-tightening performance of the pre-tightening assembly 10, the pre-tightening seat 101 provided by this utility model includes a pair of liner plates 1011 and a pressure plate 1012 disposed at the bottom of the liner plates 1011. The liner plates 1011 are provided with a transition port 1013, and the transition port 1013 is provided with a plurality of clamping ports 1014 that cooperate with the first positioning bolt 8. The bottom of the pressure plate 1012 is provided with a limiting tube 1015, which is used to limit the top end of the pre-tightening spring 102. The pre-tightening seat 101 can be installed in advance before the vertical tube 2 and the connecting seat 3 are installed, or it can be installed after the second adjustment hole 31 is selected by the first positioning bolt 8. If the latter installation procedure is adopted, the pre-tightening seat 101 is installed from bottom to top. The liner 1011 is inserted into the first positioning bolt 8 by inserting it from the top. The first positioning bolt 8 slides through the transition port 1013 and is locked in the clamping port 1014 until the pre-tightening seat 101 is pushed into the appropriate position. If the spring is pressed between the limiting tube 1015 and the seat surface of the connecting seat 3, the pre-tightening spring 102 can be used to complete the elastic tension, thereby obtaining the pre-tightening effect on the first positioning bolt 8.

[0027] In order to improve the fit performance between the connecting seat 3 and the vertical tube 2, the connecting seat 3 provided by this utility model includes a pair of upright plates 32 symmetrically distributed about the vertical tube 2. The bottom of the upright plate 32 is provided with a base plate 33. The base plate 33 is connected to the trailer by the second positioning bolt 9. In addition to clamping and connecting the vertical tube 2, the upright plate 32 also provides a reasonable installation space for the pre-tightening component 10.

[0028] To improve the structural strength of the hanging beam 1, the bottom of the hanging beam 1 provided by this utility model is provided with a pair of reinforcing plates 11. The reinforcing plates 11 are in the shape of an inverted isosceles trapezoid. The reinforcing plates 11 are fixed to the vertical square tube 2 by at least a pair of bolts. The horizontal support span and the longitudinal support surface of the reinforcing plates 11 are conducive to improving the support strength of the hanging beam 1 after hanging garden tools.

[0029] To improve the utilization rate of this device, the present invention provides upward-curving curved plates 12 at both ends of the hanging beam 1. The cross-section of the curved plate 12 is C-shaped, and a limiting port 121 is provided in the middle of the curved plate 12. For some long rod-type tools, the rod body of the tool is placed within the vertical projection range of the limiting port 121, and the head end of the tool is locked in the C-shaped port of the curved plate 12. This allows the tool to be suspended and fixed, thereby improving the utilization rate of the device.
