[0002] A backpack spray duster is a portable spraying device, usually supported by a backpack strap system, which allows the operator to carry it on his back for easy movement and operation. It is mainly used to spray liquid or powdered substances such as pesticides, insecticides, herbicides, etc. in the fields of agriculture, gardening, lawn care, etc. The spray duster sprays liquid or powdered substances through compressed air or mechanical pumps to cover the target surface to achieve the purpose of application or treatment. This equipment has a wide range of applications in agricultural production and gardening management.

[0003] At present, the existing combined frames for backpack spray powder sprayers on the market have the following disadvantages:
