[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] Combination Figure 1 The utility model provides a connecting piece for a main frame of a circular tube gripper, comprising a circular tube sleeve rod 1, on both sides of which adjustable extrusion pieces 2 are movably provided, and a fixed sleeve frame 3 is movably sleeved on the circular tube sleeve rod 1, and a total of six groups of adjustable extrusion pieces 2 are provided on both sides of the circular tube sleeve rod 1, with three groups provided on one side, and the three groups of adjustable extrusion pieces 2 are provided in a circular array about the center of the circular tube sleeve rod 1, and two groups of the fixed sleeve frame 3 are provided, which correspond to the adjusting extrusion pieces 2 on both sides respectively, and the two ends of the circular tube sleeve rod 1 are fitted with circular tubes to be connected, and the fixed sleeve frame 3 is rotatably provided within the limit range between the two groups of adjusting extrusion pieces 2.

[0027] Specifically, the round tube sleeve rod 1 of this connector is provided with a variety of forms, such as a straight type and a right-angle type, etc., so that the adjusting extrusion pieces 2 at both ends can change the connection angle, and the adjusting extrusion pieces 2 can limit the fixed positions of the two sets of fixed sleeve frames 3. Before using this connector, the fixed sleeve frame 3 needs to be rotated to the middle of the round tube sleeve rod 1, and separated from the periphery of the adjusting extrusion piece 2, so that the adjusting extrusion piece 2 can be rotated open, and the two ends of the round tube sleeve rod 1 are inserted or rotated to connect the round tube. After the round tube is connected, the adjusting extrusion piece 2 is rotated until it fits together with the round tube, and then the fixed sleeve frame 3 is rotated until it is squeezed and fixed on the periphery of the adjusting extrusion piece 2. The adjusting extrusion piece 2 forms a natural extrusion on the round tube sleeve rod 1, and the fixation is completed.

[0028] The utility model is further described below in conjunction with embodiments.

[0029] Embodiment 1:

[0030] Combination Figure 2-Figure 5 The round tube sleeve rod 1 includes a steering round rod 11, and internal thread sleeves 12 are fixedly provided at both ends of the steering round rod 11. The angle between the two ends of the steering round rod 11 can be set to a variety of models. The setting of the internal thread sleeve 12 allows the round tube sleeve rod 1 to be rotatably connected and fixed to the round tube.

[0031] A pipe opening 13 is provided inside the steering round rod 11, and the pipe opening 13 is fitted to the inner size of the round tube.

[0032] The outer end of the steering round rod 11 is provided with a snap-fitting groove 14 corresponding to the rotation position of the adjusting extrusion piece 2 . There are six snap-fitting grooves 14 . A rotating rod is built in the snap-fitting groove 14 , and the snap-fitting groove 14 is rotatably connected to the adjusting extrusion piece 2 .

[0033] Embodiment 2:

[0034] Combination Figure 6 The adjusting extrusion member 2 includes a rotating rod 21 rotatably connected to the steering round rod 11, and the rotating rod 21 can be rotated to be completely engaged in the engaging groove 14. The rotating rod 21 can be rotated to adjust the clamping angle, so that this connector can connect round tubes of different diameters within a certain range.

[0035] A limit block 24 is fixedly provided at the side end of the rotating rod 21. The movable range of the fixed sleeve 3 is between the limit blocks 24 on both sides of the round tube sleeve 1. The limit blocks 24 can block the fixed sleeve 3 to prevent the fixed sleeve 3 from falling out.

[0036] The outer side of the rotating rod 21 is provided with a rotating tooth 22, and the inner side of the rotating rod 21 is connected with a rubber pad 23. The rotating tooth 22 enables the fixed sleeve 3 to rotate to squeeze and fix the round tube. The setting of the rubber pad 23 increases the squeezing friction between the rotating rod 21 and the round tube to maintain a stable connection.

[0037] The inner side of the fixed sleeve frame 3 is provided with a threaded opening 31 , and the threaded opening 31 and the rotating teeth 22 fit each other to achieve a rotational connection.
