The control part 300 is arranged in a U-shaped structure, which cooperates with the first connecting part 100 and the second connecting part 200 to apply a clamping torque to the movable gripper 400 or release the clamping torque when the movable gripper 400 moves.


The movable claw 400 has an arc structure, which cooperates with the first claw 201 and the second claw 202 to form a clamping opening for clamping wood blocks or charcoal.


The connecting assembly 500 is arranged in a segmented structure, and adopts a movable joint structure 501, which is respectively connected with the control part 300 and the movable gripper 400, and is used for transmitting or releasing the clamping torque to the movable gripper 400.


The movable joint structure 501 is arranged at the joint between the two sections, each with a ring, and the two rings are connected by a screw or a pot nail, taking the screw or the pot nail as the axis to form a movable joint capable of rotating 360 degrees.


Specifically, one end of the first connecting part 100 is set as an opening structure (corresponding to 102).


One end of the second connecting part 200 is detachably connected with one end of the first connecting part 100 provided with an opening structure (corresponding to 102).


Specifically, one end of the opening structure (corresponding to 102) of the first connecting part 100 is embedded in the opening structure (corresponding to 203) of one end of the second connecting part 200, so that the first connecting part 100 and the second connecting part 200 can be detachably arranged.


The control part 300 is arranged at the lower side of the first connecting part 100 and is movably connected with the first connecting part 100.

The outer diameter of the first connecting part 100 is greater than that of the ring member 101, and the outer diameter of the ring member 101 is greater than or equal to that of the second connecting part 200. When the first connecting part 100 is mated with the second connecting part 200, the ring member 101 is embedded in the second connecting part 200 and extends to the second connecting part through an opening 203 at one end thereof.


In some embodiments, in order to improve the flexibility of the gripper, as shown in FIG. 8, the connecting assembly 500 can be arranged in a rotatable folding arrangement, wherein a movable joint structure 501 is arranged in the middle section of the connecting assembly 500, and the connecting assembly 500 can rotate 360 degrees through the movable joint structure 501 as the axis.


In some embodiments, in order to improve the convenience of gripper assembly, as shown in FIGS. 4, 7 and 9, a connecting part 20a can be arranged at the other end of the second connecting part 200, and the connecting part 20a and the second connecting part 200 can be integrally formed or detachably arranged.


Specifically, the upper end of the connecting part 20a is provided with a notch 20b, and one end (corresponding to 40a) of the movable claw 400 is embedded in the notch 20b of the connecting part 20a, and symmetrical openings 20c are provided on both sides of the notch 20b.


Further, as shown in FIG. 2, the upper end of the connecting part 20a is detachably connected with the movable gripper 400 through a first screw 600. One end (corresponding to 40a) of the movable gripper 400 is respectively provided with a first through hole 401 and a second through hole 402.
