The box is square, the arm lock subassembly has four, and the rack in four arm lock subassemblies is worn to establish respectively on four surfaces of box, and all leaves the space between four racks.
According to the invention, because the inner part and the outer part of the aluminum pipe are stably and effectively supported and clamped, the problems of deformation and damage of the end of the aluminum pipe in the subsequent cold drawing process can be effectively avoided. During practical application, two locking devices can be arranged, after the two ends of the aluminum pipe are locked, the base can be pushed to slide, and cold drawing of the aluminum pipe is achieved. The aluminum pipe clamping device has the advantages of being exquisite in structure, convenient to use and capable of effectively avoiding deformation and damage of the end of the aluminum pipe after clamping.

Detailed Description
As shown in fig. 1-5, the locking device includes a base 41, a friction plate 42, a driving disk 43, a spring 44, a driving shaft 45, a box 46, a supporting column 47 and a plurality of clamping arm assemblies;
the friction plate 42 is vertically arranged and fixedly connected to one side of the top surface of the base 41, the box body 46 is hollow and fixedly connected to the other side of the top surface of the base 41, the driving shaft 45 is horizontally arranged and penetrates through the box body 46, a gap is reserved between one end of the driving shaft 45 and the friction plate 42, the other end of the driving shaft 45 is detachably connected with the supporting column 47, and the supporting column 47 and the driving shaft 45 are coaxial; the center of the driving disk 43 is fixedly connected with one end of the driving shaft 45 close to the friction plate 42, and the spring 44 is abutted between the driving shaft 45 and the box body 46, so that the driving disk 43 is normally abutted against the friction plate;
