[0028] like Figure 1-6 As shown, an insulating spray gun for live cleaning includes a spray gun body 1. A handle 2 and a trigger 3 are mounted and connected to the bottom of the spray gun body 1. An auxiliary pressing mechanism 4 for pressing the trigger 3 is connected to the handle 2.

[0029] The grip 2 has a circular groove 21 in the middle, and the auxiliary pressing mechanism 4 is rotatably connected to the groove 21 of the grip 2. The auxiliary pressing mechanism 4 includes a collar 41, and hinge ears 42 are provided on opposite sides of the collar 41. The hinge ears 42 are hinged to a U-shaped buckle 43, and the rod of the U-shaped buckle 43 is an elastic element.

[0030] In this embodiment, the auxiliary pressing mechanism 4 is used to assist pressing the handle 2. When the operator needs to hold the spray gun for a long time, the U-shaped buckle 43 is fastened to the trigger 3, so that the U-shaped buckle 43 keeps pressing the trigger 3. When it is necessary to release the trigger 3, the U-shaped buckle 43 can be moved downward and removed. The collar 41 is rotatably connected to the annular groove 21 in the middle of the handle 2, so the collar 41 can rotate relative to the handle 2. At the same time, the position of the hinge ear 42 can rotate. The U-shaped buckle 43 is hinged to the hinge ear 42, and the U-shaped buckle 43 can rotate relative to the hinge ear 42. The rod of the U-shaped buckle 43 is an elastic element, so it can undergo elastic deformation. When the trigger 3 is fastened, the U-shaped buckle 43 undergoes elastic deformation to achieve the fastening of the trigger 3. In this embodiment, after the trigger 3 moves parallel to the handle 2, the spray gun body 1 is in the working state.

[0031] Reference Figure 4The upper end of the grip 2 has a circular rotating groove 22, and the rotating groove 22 is rotatably connected to the abutment 5. The distance from one edge of the abutment 5 to the center of the rotating groove 22 is greater than that of the other side of the abutment 5. In this embodiment, the rotating groove 22 is used to install the abutment 5, so that the abutment 5 is rotatably connected to the rotating groove 22. The coefficient of friction between the abutment 5 and the rotating groove 22 is high, and the abutment 5 can only rotate when the operator manually rotates it. When one side of the abutment 5 is rotated to the position of the trigger 3, the trigger 2 is restricted, and the trigger 2 will not be pressed when it is accidentally pressed.

[0032] Reference Figure 6 The U-shaped buckle 43 includes a connecting cylinder 431 and a U-shaped rod 432. The end of the U-shaped rod 432 is located inside the connecting cylinder 431, and a spring 433 is provided between the end of the U-shaped rod 432 and the opening of the connecting cylinder 431. In this embodiment, the U-shaped rod 432 slides inside the connecting cylinder 431. When the U-shaped rod 432 is stretched, the end of the U-shaped rod 432 compresses the spring 433, and the spring 433 tends to return to its original position.

[0033] The end of the connecting cylinder 431 is threaded, and a threaded cap 434 is threadedly connected to the end of the connecting cylinder 431. The threaded cap 434 has a through hole for the U-shaped rod 432. In this embodiment, the threaded cap 434 is threadedly connected to the connecting cylinder 431, and the threaded cap 434 can be separated from the connecting cylinder 431. When the threaded cap 434 is removed, the U-shaped rod 432 can be separated from the connecting cylinder 431.

[0034] Reference Figure 6 A limiting plate 435 is fixedly connected to the end of the U-shaped rod 432, and a spring 433 is located between the limiting plate 435 and the threaded cap 434. In this embodiment, the diameter of the limiting plate 435 is larger than the diameter of the U-shaped rod 432, and the spring 433 is sleeved on the outside of the U-shaped rod 432. When the U-shaped rod 432 is stretched outward, the limiting plate 435 and the threaded cap 434 together compress the spring 433.

[0035] Reference Figure 3 The edges of the abutment plate 5 are smoothly transitioned, and both sides of the abutment plate 5 are arc surfaces, which are connected by a plane. In this embodiment, the abutment plate 5 has a circular hole, which is rotatably connected to the handle 2. When the side of the abutment plate 5 that is farther from the center of the handle 2 is rotated to the position of the trigger 3, the trigger 3 is restricted to the released state, thereby effectively preventing accidental activation of the trigger 3.

[0036] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
