[0028] See Figure 2 The first probe rod 41 includes a rectangular tube 411, a slide rod 412 is slidably inserted in the rectangular tube 411, and a connecting rod 413 is coaxially provided at the lower end of the slide rod 412, and a tester 5 is provided at the lower part of the rectangular tube 411;

[0029] The instrument panel of the tester 5 is integrated with an angle meter, and the tester includes a pull-wire column 51 around which a pull-wire is wound, and one end of the pull-wire is bolted to the connecting rod 413;

[0030] See Figure 3 and Figure 4The tester 1 includes a cubic shell 52, one end of which is a dashboard 53. A wire encoder 54 is provided in the shell 52. One end of the wire encoder 54 is rotatably connected to a wire column 51. The wire column 51 passes through the shell 52 and is wound with a wire. A circular baffle 55 is coaxially fixed to the protruding end of the wire column 51 by bolts.

[0031] Each positioning block is in the shape of a right-angled triangle. Each positioning block is provided with a positioning slider. The positioning slider slides with the corresponding inner groove of the positioning rod so that each positioning block is connected to the inner side of the corresponding positioning rod, and the right-angle side of the positioning block is perpendicular to the positioning rod.

[0032] A pair of oblique sides of a pair of positioning blocks 11 on the positioning rod are arranged opposite to each other and are used to position the wheels of the forklift.

[0033] One end of the pin 3 passes through the side wall of the rectangular tube 411 and is connected to the rectangular tube 411.

[0034] The other end of the pin shaft 3 is provided with a flat cylindrical probe slider, and the probe slider cooperates with the outer sliding groove of the corresponding positioning rod, so that the first probe rod 41 is slidably connected to the outer side of the corresponding positioning rod.

This L1 and the angle a can calculate L2 and L3. L4 is known, b=arctan(L2+L4) / L3.) The approach angle of the forklift can be measured in the same way.

[0039] 2. Minimum ground clearance measurement method: by stretching and shortening the first probe rod 41 and the second probe rod 42, the second probe rod 42 is made to contact the lowest point of the vehicle counterweight, and then the minimum ground clearance can be directly read through the display 5 (principle: by pulling the connecting rod 413 in the rectangular tube 411, the pull line is pulled out, and the oblique length L1 from the measuring position to the center of the pin can be calculated. This L1 and the angle a can be used to calculate the vertical distance L2 from the measuring position to the center of the pin. The vertical distance L4 from the center of the pin to the horizontal road surface is known, and the sum of L2 and L4 is the minimum ground clearance).
