DETAILED DESCRIPTION

[0021] Embodiment 1: A preferred embodiment of the utility model provides a backpack sprayer, including a liquid storage tank 110, a support plate 120, a first spring 150, a vertical rod 160, a second spring 170, a ring 190, an insertion rod 191 and a connecting rod 192. A groove 140 is opened on the liquid storage tank 110, one end of the first spring 150 is fixed in the groove 140, and the vertical rod 160 is slidably inserted in the groove 140. The other end of the first spring 150 and the upper end of the vertical rod 160 are fixed together, and the lower end of the vertical rod 160 is fixed on the upper surface of the support plate 120. A first rubber pad 130 is fixed on the upper surface of the support plate 120, and the vertical rod 160 passes through the first rubber pad 130. The arrangement of the first rubber pad 130 is convenient for protecting the lower surface of the liquid storage tank 110 to prevent it from being damaged by collision with the support plate 120.

[0022] There are two rings 190, one of which is fixed in the liquid storage tank 110, and the insertion rod 191 slides through the ring 190, and the other ring 190 is fixed on the outer wall of the insertion rod 191, the second spring 170 is fixed between the two rings 190, and the insertion rod 191 penetrates the second spring 170, and a second slot 196 is opened on the liquid storage tank 110, one of the rings 190 is fixed in the second slot 196, and the other ring 190 is slidably set in the second slot 196 Inside, the second spring 170 is arranged in the second slot 196. The setting of the second slot 196 facilitates the movement of the insertion rod 191 on the liquid storage tank 110. One end of the insertion rod 191 is inserted into the vertical rod 160. A plurality of first slots 193 are provided on the vertical rod 160. The plurality of first slots 193 are linearly equidistantly arranged on the vertical rod 160. The setting of the plurality of first slots 193 facilitates the adjustment of the length of the vertical rod 160 protruding from the liquid storage tank 110. The other end of the insertion rod 191 is fixed to the connecting rod 192.

[0023] Embodiment 2: A preferred embodiment of the utility model provides a backpack sprayer, which differs from the above embodiments only in that it also includes a protrusion 194, which is fixed on the outer wall of the support plate 120, and the protrusion 194 and the connecting rod 192 are arranged correspondingly. The arrangement of the protrusion 194 facilitates stepping on the support plate 120.

[0024] Embodiment 3: A preferred embodiment of the utility model provides a backpack sprayer, which differs from the above embodiments only in that it also includes a second rubber pad 195, which is fixed on the outer wall of the liquid storage tank 110.
