[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] For reference Figure 1-3 The utility model is described as follows:

[0018] Embodiment 1: A lifting and deforming connection structure comprises a first connection head 1, a second connection head 2, a third connection head 3, and an adjusting rod 4. The first connection head 1, the second connection head 2, and the third connection head 3 can be connected to a tubular part respectively.

[0019] The first connector 1 and the second connector 2 are respectively rotatably connected to the adjustment rod 4 to adjust the angle position, and the third connector 3 can be adjusted in height on the adjustment rod 4. The adjustment rod 4 is vertically arranged, the first connector 1 and the second connector 2 are connected to the left and right sides of the upper end of the adjustment rod 4, and the third connector 3 is connected to the lower end of the adjustment rod 4.

[0020] The adjusting rod 4, as the main supporting component of the entire connecting structure, provides stable support for the first connecting head 1, the second connecting head 2 and the third connecting head 3. At the same time, its vertical arrangement provides a clear guide for the height adjustment of the third connecting head 3.

[0021] The rotational connection between the first connector 1 and the second connector 2 can adjust the angular position on the left and right sides of the upper end of the adjusting rod 4, which increases the flexibility when connecting with the tubular parts and can adapt to the connection requirements of different angles.

[0022] The height of the third connector 3 can be adjusted by adjusting the height position on the adjusting rod 4 , so that the height position of the third connector 3 can be flexibly determined according to actual installation requirements.

[0023] The combination of angle adjustment and height adjustment enables the connection structure to meet diverse connection requirements. During installation, each connector can be adjusted according to the actual situation on site, reducing installation difficulties caused by position deviation of tubular parts.

[0024] The third connector 3 is threadedly connected to the adjustment rod 4. The third connector 3 is a tubular structure with a closed upper end. A threaded hole 5 is provided at the center of the upper end surface of the third connector 3. The adjustment rod 4 is threadedly connected in the threaded hole 5. By rotating the third connector 3, it can be gradually raised or lowered on the adjustment rod 4 as needed to reach an ideal height position. The meshing of the threads can provide a certain self-locking ability, so that the third connector 3 can remain stable after being adjusted to a suitable position, and it is not easy to change the height due to vibration or other external forces.

[0025] The threaded connection between the third connector 3 and the adjusting rod 4 and the design of the tubular structure not only meet the requirements of height adjustment, but also ensure the stability and reliability of the connection.

[0026] The right end of the first connector 1 forms a U-shaped connection groove 6, which provides a space for accommodating and fixing the connection block 7 of the second connector 2, and its shape is conducive to the insertion and positioning of the connection block 7. The left end of the second connector 2 is provided with a connection block 7, which is inserted into the connection groove 6 and forms a rotation connection, so that the second connector 2 can be adjusted in angle relative to the first connector 1. The connection block 7 is provided with an axial hole 8, and the first connector 1 is provided with a connection hole 9 coaxially corresponding to the axial hole 8. The connection hole 9 is connected to the connection groove 6, and the upper end of the adjustment rod 4 is connected to the connection hole 9 and the axial hole 8. The upper end of the adjustment rod 4 is threadedly connected to the connection hole 9, and the axial hole 8 and the connection hole 9 are coaxially corresponding, providing an accurate position for the connection of the adjustment rod 4. The adjustment rod 4 is not only fixed by being threadedly connected to the connection hole 9, but also can transmit torque and bear load.

[0027] The matching mode of the connection groove 6 and the connection block 7 makes the structure compact and saves space. The second connector 2 is allowed to rotate freely within a certain range relative to the first connector 1, which increases the angular adaptability of the connection structure. The threaded connection between the adjustment rod 4 and the connection hole 9 and the matching with the shaft hole 8 provide stable support and connection, ensuring the reliability of the structure during angle adjustment and operation.

[0028] The connecting pipes of the first connector 1 and the second connector 2 are both tubular structures, which are convenient for connecting with tubular parts. Similar in shape to the tubular parts, they can better fit and connect, reduce gaps and mismatches at the connection parts, and thus improve the sealing and stability of the connection.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
