[0007] The mounting platform comprises a platform bottom plate and a profile bracket, and the middle part of the profile bracket is fixedly connected with the horizontally arranged platform bottom plate.

[0008] Each corner of the profile bracket is fixedly provided with a right-angle connecting plate.

[0009] A universal rotating wheel is fixedly installed at the lower end of the profile bracket.

[0010] The lower end of the profile support is fixed with a wire body fixed connection plate.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model discloses an integrated electric gun controller, blocking cylinder and tightening gun, realizes automatic tightening operation, avoids the inefficient operation of manual use of limited torque wrench tightening, can quickly respond to equipment or handheld electric gun failure, reduces the process of manual use of air gun plus limited torque wrench tightening, thereby improve production efficiency and quality assurance degree, alleviate the operation difficulty of staff, improve engine assembly quality, improve the smoothness and efficiency of production process, satisfy the demand of modern production line to automatic assembly.
