[0009] Preferably, the fixing assembly includes a clamp, and two groups of the clamps are evenly arranged at the bottom of the connecting block, and a cylindrical pin is arranged at the bottom of the inner side wall of the right clamp in the two groups of the clamps.

[0010] Preferably, an electric torque gun is clamped and fixed in the two groups of clamps, a positioning hole is opened on the top of the shell of the electric torque gun, and the cylindrical pin corresponds to the positioning hole.

[0011] Preferably, the stopper is L-shaped, and the bottom of the stopper fits with the top of the connecting block.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the utility model is used, the cylindrical pin on the clamp is aligned and inserted into the positioning hole on the electric torque gun, the clamp is locked, the tooling is fixed on the electric torque gun, and the stopper is adjusted to a suitable angle by the shaft pin on the tooling. At this time, when the electric torque gun is used to tighten the bolt, the stopper will press against the edge of the automobile part, and a reverse force will be provided to offset the force brought by the electric torque gun when fixing the bolt, making the gun shooting safer, protecting workers and automobile parts, and eliminating unnecessary risks when shooting.
