[0015] The utility model discloses the following beneficial technical effects are possessed by adopting the above technical scheme:

[0016] 1, the device can be used to pick longan, and the longan can be picked on the ground, realizing safe and efficient picking of longan.

[0017] 2, the device can not only be used to pick longan, but also can be applied to other string fruits or single fruit picking on tree branches.

[0018] 3, the device has simple structure, low cost and convenient operation.

[0019] 4, by adjusting the number of gaskets, the position of the clamping block can be adjusted to ensure that the clamping can effectively clamp the cut end of the tree branch (the knot - string fruit or the single fruit on the tree branch). DRAWINGS

[0020] The utility model will be further described in detail in combination with the drawings and specific embodiments:

[0021] Figure 1 It is the overall structure schematic diagram (the hollow pipe front end is in the state of being cut open) of the utility model;

[0022] Figure 2 It is the partial enlarged view in Figure 1

[0023] Figure 3 It is the schematic diagram of the fixing frame. SPECIFIC EMBODIMENTS

[0024] As shown in Figures 1-3 , the device for picking longan comprises a hollow pipe 1, a push rod 2, a fixing frame 3, a clamping block 4 and a cutter 5.

[0025] The fixing frame 3 is fixed at the front end of the hollow pipe 1, and the front end of the fixing frame 3 is provided with a tree branch limiting groove 31, and the top of the tree branch limiting groove 31 is provided with a tree branch guide inlet 32;

[0026] The push rod 2 penetrates through the hollow pipe 1, and the push rod 2 is fixed with a sliding block 21 which is slidably sleeved with the inner cavity of the hollow pipe 1, and the sliding block 21 and the inner side wall of the front end of the hollow pipe 1 are connected with a compression spring 8 which is sleeved on the push rod 2;

[0027] The rear end of the push rod 2 is fixed with a handle 6, and the front end of the push rod 2 is fixed with a connecting plate 7, and the connecting plate 7 is fixed with the clamping block 4 and the cutter 5 which are towards the tree branch limiting groove 31 at intervals, and the length of the cutter 5 is longer than that of the clamping block 4.
