DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Embodiment 1:

[0022] like Figure 1-3 As shown, a spray gun mechanism for spraying in this embodiment includes a gun body 1, and the gun body 1 includes a handle 11, a barrel 12, a paint joint 13 and a trigger 14. The bottom of the handle 11 of the gun body 1 is rotatably connected to a connecting rod 3, one end of the connecting rod 3 is fixedly connected to a bending rod 32, and the end of the bending rod 32 away from the connecting rod 3 is fixedly connected to an extension rod 33. A person's arm is usually wider than the gun body 1. Through the arrangement of the bending rod 32, the two extension rods 33 can be located on both sides of the user's arm, and the end of the extension rod 33 away from the bending rod 32 is fixedly connected to a strap 34. When holding the gun body 1, the strap 34 is used to support the bottom of the user's arm, so that the arm can provide support to the gun body 1 and alleviate the problem of wrist pain.

[0023] Specifically, the two sides of the bottom of the handle 11 are fixedly connected with the positioning shaft 21, and a circular hole 31 is opened on one side of the connecting rod 3. The connecting rod 3 is rotatably connected to the outer surface of the positioning shaft 21 through the circular hole 31, so that the connecting rod 3 can rotate and the extension rod 33 can be folded when not in use.

[0024] Specifically, one end of the positioning shaft 21 away from the handle 11 is fixedly connected to the limiting block 23 to prevent the connection rod 3 from falling off.

[0025] Specifically, the two sides of the bottom of the handle 11 are fixedly connected with the limit strips 22, and the limit strips 22 are located below the positioning shaft 21. After the extension rod 33 is unfolded, the limit strips 22 support the bottom of the connecting rod 3, thereby limiting the extension rod 33 so that it will not continue to rotate, ensuring that the extension rod 33 can provide support force to the gun body 1.

[0026] Specifically, a nozzle 15 is fixedly installed at the outlet of the gun barrel 12, a paint pot 16 is fixedly installed on the outer surface of the paint joint 13, and a hook 17 is fixedly connected to the top of the gun barrel 12, so that the gun body 1 can be hung conveniently when not in use.

[0027] Embodiment 2, a spray gun mechanism for spraying in this embodiment is different from that in Embodiment 1 in that:

[0028] like Figure 4 As shown, the extension rod 33 includes a telescopic rod 331 and a sleeve 332. The sleeve 332 is slidably sleeved on the outer surface of the telescopic rod 331, and the strap 34 is fixedly connected to the sleeve 332. By sliding the telescopic rod 331 in the sleeve 332, the length of the extension rod 33 can be adjusted, so that the length of the extension rod 33 can be appropriately adjusted according to the length of the user's arm. It is suitable for different users and users with longer arms can operate it more labor-saving.

[0029] Further preferably, a rubber pad is fixedly connected to the inner wall of the sleeve 332. The rubber pad is relatively soft and can increase the friction between the telescopic rod 331 and the sleeve 332. Therefore, by pulling the sleeve 332 with force, the sleeve 332 can slide on the outer surface of the telescopic rod 331. Without using force, the sleeve 332 will not slide on the surface of the telescopic rod 331, thereby avoiding the problem of the sleeve 332 falling off and being lost when not in use.

[0030] The working principle of the utility model is as follows: when in use, the extension rod 33 is unfolded, the user's hand holds the handle 11, and the strap 34 at the end of the extension rod 33 is located below the user's arm, so that the gun body 1 droops due to the weight of the paint pot 16, and the user's arm presses down the extension rod 33 through the strap 34, thereby using the principle of the tilting rod to provide support force for the gun body 1, thereby reducing the force on the wrist and alleviating the problem of wrist soreness.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. Unfold the extension rod 33. When holding the gun body 1, the strap 34 at the end of the extension rod 33 is located under the user's arm. The user's arm presses down the extension rod 33 through the strap 34, thereby using the principle of the tilting rod to provide support for the gun body 1, thereby reducing the force on the wrist and alleviating the problem of wrist pain.

[0033] 2. The extension rod 33 includes a telescopic rod 331 and a sleeve 332, so that the length of the extension rod 33 can be adjusted. Therefore, the length of the extension rod 33 can be appropriately adjusted according to the length of the user's arm, which is suitable for different users, and users with longer arms can operate more labor-saving.

[0034] 3. By providing a rubber pad on the inner wall of the sleeve 332, the friction between the telescopic rod 331 and the sleeve 332 can be increased. When no force is applied, the sleeve 332 will not slide on the surface of the telescopic rod 331, thereby avoiding the problem of the sleeve 332 falling off and being lost when not in use.
