[0038] The upper end and the lower end of the adjusting sliding block 3 are fixedly connected with symmetrically distributed mounting racks 11, the front surface of the mounting rack 11 is provided with mounting holes 12 arranged in a linear array, the shape and size of the mounting rack 11 are designed according to the structure of the electric vehicle fork guard plate, and the mounting rack 11 can be tightly matched with the electric vehicle fork guard plate and can bear the weight of the electric vehicle fork guard plate, the diameter and spacing of the mounting hole 12 are designed according to the installation requirements of the electric vehicle fork guard plate, and the electric vehicle fork guard plate can be firmly installed on the mounting rack 11 by using standard bolts and nuts.

[0039] The working process of the utility model is as follows:

[0040] Step one, when the electric vehicle fork guard plate needs to be installed, first, the position of the mounting rack 11 is determined according to the size and mounting hole requirement of the guard plate, then the hexagonal wrench is inserted into the hexagonal groove 7 in the front surface of the annular rotating block 6, when the hexagonal wrench is rotated, the annular rotating block 6 is rotated in the through hole 5, the worm 8 is also rotated, the worm 8 is engaged with the worm wheel 91, when the worm 8 is rotated, the worm wheel 91 is rotated, and the rotation of the worm wheel 91 drives the first rotating rod 9 to rotate in the mounting cavity 4;

[0041] Step two, the rotation of the first rotating rod 9 drives the first bevel gear 92 to rotate, the rotation of the first bevel gear 92 drives the second bevel gear 95 to rotate, the rotation of the second bevel gear 95 drives the second rotating rod 94 to rotate, and the rotation of the second rotating rod 94 drives the spur gear 96 to rotate, and the spur gear 96 is engaged with the rack 97 fixedly connected to the front surface of the mounting block 1, and moves on the rack 97 when the spur gear 96 is rotated;

[0042] Step three, since the adjusting sliding block 3 and the spur gear 96 are connected together through the second rotating rod 94, the movement of the spur gear 96 drives the adjusting sliding block 3 to move in the guide sliding groove 2 in the front surface of the mounting block 1, the movement of the adjusting sliding block 3 drives the mounting rack 11 to move and adjust, and when the mounting rack 11 moves to the appropriate position and the mounting hole 12 is aligned with the mounting hole position of the electric vehicle fork guard plate, the hexagonal wrench is taken out.

[0043] Step four, at this time, because the worm wheel 91 and the worm 8 have self-locking characteristics, that is, only the worm wheel 91 can be driven to rotate by the worm 8, and the worm wheel 91 cannot drive the worm 8 to rotate, so when the hexagonal wrench is removed, the worm 8 will not rotate due to external force, thereby ensuring the stability of the mounting frame 11 after adjustment, so that the bolt and nut can be used to firmly install the electric vehicle flat fork guard on the mounting frame 11, and the stable installation of the guard is ensured.

[0044] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
