The left and right sides of the return spring 802 are fixedly connected to the inner wall of the fixed housing 7 and the pusher 803, respectively. The pusher 803 is sleeved on the surface of the support column 801. The top of the pusher 803 passes through the square through hole 10 and extends to the outside of the square through hole 10 to be fixedly connected to the clamping and fixing member 804. The clamping and fixing member 804 contacts the fixing collar 6 on the side near the fixing collar 6.

[0040] The working principle of this utility model:

[0041] In use, flipping the control switch 901 upwards causes the control rack 903 to rise on the surface of the limit post 902. The control rack 903 drives the control gear 904 to rotate, which in turn drives the control linkage 905 to rotate. The control linkage 905 then moves the moving post 906 within the moving groove 805. The moving post 906 moves the pushing member 803 on the surface of the support post 801, compressing the return spring 802. The pushing member 803 then moves the clamping and fixing member 804 synchronously. When the clamping and fixing member 804 opens, the feed tube 5... Place it in the appropriate position and connect it to the powder pump 3. After the connection is completed, release the control switch 901. The force released after the return spring 802 is squeezed will drive the pusher 803 and the clamping and fixing member 804 to move in the opposite direction. The pusher 803 will drive the moving column 906 to move in the opposite direction in the inner cavity of the moving groove 805. The moving column 906 will drive the control linkage 905 and the control gear 904 to rotate in the opposite direction synchronously. The control gear 904 will drive the control rack 903 and the control switch 901 to descend and reset synchronously. When the clamping and fixing member 804 contacts the fixing collar 6, the fixing is completed.

[0042] In summary, this surface spraying device for advertising signs, through the coordinated use of a fixing collar 6, a fixing device 8, and a control device 9, solves the problem that in existing powder coating machines, the feed pipe used to connect the spray gun and the powder pump is mostly directly sleeved on the surface of the powder pump for connection. However, in this connection method, the feed pipe may be pulled off during use, causing the spraying work to be interrupted and affecting production efficiency.
