[0026] Compared with the related art, the special-shaped copper tube welding support and fixing device provided by the utility model has the following beneficial effects:

[0027] The special-shaped copper tube welding support fixing device is convenient for clamping the special-shaped copper tube by setting the first fixing plate 5, the second fixing plate 6, the bidirectional screw rod 10, the hand wheel 3, the electric push rod 12, and the arc extrusion plate 13.

[0028] Second embodiment

[0029] Please refer to Figure 1-4 Based on the special-shaped copper tube welding support and fixing device provided in the first embodiment of the present application, the second embodiment of the present application proposes another special-shaped copper tube welding support and fixing device.

[0030] Specifically, the difference of the special-shaped copper tube welding support and fixing device provided in the second embodiment of the present application is that the electric push rods 12 are provided in multiple groups, and each group of electric push rods 12 is independently controlled. By providing multiple groups of arc-shaped clamping plates, it is convenient to improve the comprehensive clamping and fixing of the special-shaped copper tube.

By setting up the controller 2, it is convenient to control the electrical components inside the device. The control circuit of the controller 2 can be realized through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0035] It should be noted that all kinds of components used in this application document are standard parts and can be purchased on the market. The specific connection methods of each part adopt conventional means such as mature bolts, rivets and welding in the existing technology. Machinery, parts and electrical equipment all adopt conventional models in the existing technology. Circuit connections adopt conventional connection methods in the existing technology. Electrical equipment are connected to an external safe power supply, and no specific description is given here.

[0036] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
