Embodiment 1
[0043] Example 1, such as figure 1 with figure 2 As shown, the handling truck in this embodiment includes a first lifting rod 11, a second lifting rod 12, a clamping mechanism, a driving mechanism and a controller. There are two first lifting rods 11, which are arranged on the left and right. Each first lifting rod 11 is provided with a front guide wheel 13 at the front end. There are also two second lifting rods 12, respectively corresponding to the middle of the first lifting rod 11 Mutually hinged, see Figure 5 As shown, each second lifting rod 12 has a roller 121 at the front end, a connecting portion 15 is connected between the rear ends of the two second lifting rods 12, and the bottom end of the connecting portion 15 is provided with a rear guide wheel 14 for driving The mechanism is arranged on the connecting portion 15 for driving the clamping mechanism up and down, and the controller has a first control output terminal connected with the driving mechanism.

Embodiment 2
[0051] Example 2, such as Picture 11 with Picture 12 As shown, the guide slot bracket 31 in this embodiment includes three sub-guide slot racks intersecting at one point, the angle formed between adjacent sub-guide slot racks is 120°, and the three clamping rods It can be movably installed on the respective sub-guide trough racks.
[0052] The driving source in this embodiment is the motor 7. The motor 7 is capable of forward and reverse rotation. The motor 7 has a tapered output gear 71. The bottom part of each clamping rod is provided with a slider 42 which has an inner screw hole. The motor 7 is in transmission connection with each clamping rod through a transmission mechanism. The transmission mechanism includes three screw rods 43 respectively matched with the slider 42 and three conical input gears 44 meshing with the conical output gear 71, each The screws 43 are rotatably arranged in the guide groove bracket 31, and each conical input gear 44 is arranged at the end of t...
Embodiment 3
[0053] Example 3, such as Figure 13 As shown, the driving sources in this embodiment are the motor 83 and the motor 84, the guide slot bracket 31 is T-shaped, and a slider 42 is provided at the bottom of each clamping rod. The slider 42 has an inner screw hole, and each sliding The block 42 is connected to the motor through the respective screw 43. The screw 43 and the motor are both arranged in the guide slot bracket 313. Of course, if the motor is relatively large, it can also be arranged on the back of the guide slot bracket 31, where the first clamping rod 4a passes The motor 82 is driven, and the lower second clamping rod 4b and the third clamping rod 4c are driven by the same motor 81. Refer to Example 1 for other structures and handling procedures.
