Preferably, in the present embodiment, the operation lever 151 is configured to be rotatable with respect to the chassis 110 in the front-rear direction D1. Specifically, the lever 151 is in a stationary state when the walking omni-directional forklift 100 is in the vertical position, and the lever 151 can be rotated in the rear side direction from the vertical position to adjust the walking speed of the walking omni-directional forklift 100.

In the present embodiment, when the lever 151 rotates a first angle, the chassis 110 travels at a first speed. When the lever 151 rotates a second angle, the chassis 110 walks at a second speed. It will be appreciated that the first angle and the second angle are different and that the first speed and the second speed are different. The walking omni-directional forklift 100 is switched between the first speed and the second speed by switching the operation lever 151, and the operation is simple.

The first angle and the second angle are both an angle range, so that the operation of a user is facilitated. Preferably, the first angle is alpha-beta, and the second angle is beta-90 degrees;

wherein 0 DEG < alpha < 60 DEG, alpha < beta <90 deg. The α may be a value of, for example, 25 °, 35 °, 40 °, 45 °, and the β may be a value of, for example, 45 °, 50 °, 55 °, 65 °, 70 °, 75 °.

In this embodiment, the first angle is [30 °,60 ° ], and the second angle is (60 °,90 °). In other words, when the lever 151 is turned from the vertical position to the rear side in the front-rear direction D1 in the range of 30 ° to 60 °, the walking omni-directional forklift 100 travels at the first speed. When the lever 151 is turned in the range of 60 ° to 90 ° to the rear side in the front-rear direction D1 from the vertical position, the walking omni-directional forklift 100 travels at the second speed.

In this embodiment, the first speed is greater than the second speed. For example, the first speed may be a constant speed when the walking omnidirectional forklift 100 is operating, and the second speed may be a low speed of the walking omnidirectional forklift 100, and may be suitable for use in an open scene/environment, and may be suitable for use in a scene/environment with many obstacles.

Of course, the first speed may be set to be lower than the second speed, and in this case, the speed of the walking omni-directional forklift 100 increases as the lever 151 rotates from the vertical position to the rear side.

In other embodiments of the utility model, not shown, the lever 151 may also be designed with a plurality of speed gears, for example when the lever 151 is rotated a third angle, the chassis 110 is walked at a third speed.

Or the operation lever 151 may be designed as: as the lever 151 rotates from the vertical position to the rear side, the speed of the walking omni-directional forklift 100 gradually increases or gradually decreases.

It will be appreciated by those skilled in the art that the lever 151 may be configured to rotate in other directions, corresponding to different functions of the walking omni-directional forklift 100. For example, in a stationary state, the lever 151 may be rotated circumferentially around its own axis, and the walking omni-directional forklift 100 enters the operation mode after being rotated 90 degrees to the left.

Referring to fig. 2 to 5, the operating handle 150 further includes a grip 152. A handle 152 is provided to the operation lever 151, and the handle 152 is located at the top end of the operation lever 151.
