Wherein the driving direction of the first adjusting mechanism 33 is perpendicular to the driving direction of the second adjusting mechanism 34. The spacing between the first clamping mechanism A and the second clamping mechanism B, the spacing between the third clamping mechanism C and the fourth clamping mechanism D are adjusted to match the spacing between the side edges of the truss arms; the first adjusting mechanisms 33 are used for adjusting the spacing between the first driving mechanism A and the fourth driving mechanism D as well as the second driving mechanism B and the third driving mechanism C so as to match the spacing on the other side of the truss arm; in addition, the first adjusting mechanism 33 is independently driven to a second adjusting mechanism 34, so that the position of the truss arm on the first adjusting mechanism 33 can be integrally adjusted; one specific application is that the overall height of the device is high due to the arrangement of the rotating mechanism 32, otherwise the rotation of the rotating mechanism 32 is affected, and therefore, the clamping mechanism is also at a high position; as shown in fig. 2, the rotation mechanism can rotate 90 ° to make the first adjusting mechanism 33 vertically disposed, at this time, the second adjusting mechanism 34 is driven by the two sets of first adjusting mechanisms 33 to move downward integrally, so as to reduce the operation height of the staff, and make it more convenient for the staff to mount and process the truss arm.
In the above embodiment, as shown in fig. 2 to 5, the first adjusting mechanism 33 includes the first housing 331, the first slide rail 332, the first moving plate 333, the first motor 334 and the first lead screw 335, the first lead screw 335 is rotatably disposed in the first housing 331, the first slide rail 332 is respectively disposed at both sides of the first housing 331, the first moving plate 333 is disposed on the first slide rail 332 and the first lead screw 335, and the first lead screw 335 is driven to rotate by the first motor 334.

Preferably, the second screw 345 is composed of two screws, and the two screws are connected through a coupling; the two screws are combined into the second screw 345, so that the length of a single screw is reduced, and the cost of the second screw 345 is reduced.
In an embodiment, as shown in fig. 2-5, the clamping mechanism includes a mounting seat 351, a fixing seat 352, a movable seat 353, a fourth guide rail 354 and an air cylinder 355, wherein a mounting area for mounting the air cylinder is arranged in the middle of the mounting seat 351, the fourth guide rail 354 is separately arranged at two sides of the mounting area, the movable seat 353 is arranged on the fourth guide rail 354, the fixing seat 352 is arranged on the mounting seat 351, the fixing seat 352 and the movable seat 353 are oppositely arranged, a conical positioning block 356 is arranged on the fixing seat 352, and a pressing block 357 is arranged on the movable seat 353.

In the above embodiment, the third motor 25 drives the second positioner to move, and at the moment of stopping, the second positioner continues to move forward for a small distance due to inertia, and the distance is not controllable, so that an error exists in the distance between the first positioner 3 and the second positioner 4; the third motor 25 is configured as a lock-free motor such that the horizontal position of the second displacement mechanism 4 is adjustable, thereby compensating for the distance moved by inertia.
