[0027] The positioning member 201 is provided to press the hose 102 to prevent the hose 102 from becoming loose when being rolled up or unfolded, and the anti-retraction member 202 is provided to prevent the hose 102 from moving backward when being unfolded, thereby preventing the hose 102 from getting stuck.

[0028] Example 2

[0029] Reference Figure 1 to Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0030] Specifically, the positioning member 201 includes a fixed disk 201a, a fixed column 201b, a slider 201c and a pressing roller 201d. The fixed disk 201a is rotatably connected to the outside of the reel body 101, the fixed column 201b is fixed on the fixed disk 201a, the slider 201c slides in the fixed column 201b, and the pressing roller 201d is rotatably connected to one side of the slider 201c.

[0031] The fixed disk 201a is used to position the reel body 101, the fixed column 201b is used to position the slider 201c, and the slider 201c is used to drive the pressing roller 201d to press the hose 102.

[0032] Specifically, the positioning member 201 further includes a positioning column 201e and a spring 201f. The positioning column 201e is fixed in the fixing column 201b, and the spring 201f is arranged outside the positioning column 201e.

[0033] The positioning column 201e is used to position the spring 201f, and the spring 201f is used to apply a thrust to the slider 201c, so that the pressing roller 201d and the hose 102 fit more closely.

[0034] Example 3

[0035] Reference Figure 1 to Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0036] Specifically, the anti-retraction member 202 includes a fixed frame 202a and a movable block 202b. The fixed frame 202a is fixed on the fixed plate 201a, and the movable block 202b is movable on the fixed frame 202a.

[0037] The fixed frame 202 a is provided to locate the moving track of the movable block 202 b , and the movable block 202 b is provided to locate the hose 102 .

[0038] Specifically, the anti-recoil component 202 also includes a tooth plate 202c, a gear 202d, a fixed plate 202e and an anti-recoil plate 202f. The tooth plate 202c slides in the movable block 202b, the gear 202d is rotatably connected in the movable block 202b, the tooth plate 202c is meshed with the gear 202d, the fixed plate 202e is fixed to one side of the tooth plate 202c, and the anti-recoil plate 202f is rotatably connected to the movable block 202b through a torsion spring.

[0039] There are two tooth plates 202c. Through the setting of the gear 202d, the two tooth plates 202c can be driven to move simultaneously. The setting of the fixed plate 202e is used to position the anti-retraction plate 202f. The setting of the anti-retraction plate 202f is used to prevent the hose 102 from moving backward when it is unfolded.

[0040] Specifically, the anti-retraction member 202 further includes a threaded rod 202g and a knob 201h. The threaded rod 202g is rotatably connected to the movable block 202b, and the knob 201h is fixed to one end of the threaded rod 202g.

[0041] The knob 201h is arranged to drive the threaded rod 202g to rotate, thereby driving the toothed plate 202c to move, thereby driving the gear 202d to rotate.

[0042] During use, when the hose 102 needs to be unfolded, first pull the hose 102 and turn the knob 201h, so that the knob 201h drives the threaded rod 202g to rotate, and then drives the tooth plate 202c to move, thereby driving the gear 202d to rotate, thereby driving the two tooth plates 202c to move at the same time. When the two tooth plates 202c move, they will drive the fixed plates 202e on the two tooth plates 202c to move, and then drive the two anti-retreat plates 202f to clamp the hose 102. During clamping, due to the pulling of the hose 102, the hose 102 will drive the anti-retreat plate 202f to tilt, and at the same time, the anti-retreat plate 202f will have a tendency to reset under the action of the torsion spring, thereby clamping the retreating hose 102, thereby preventing the hose 102 from getting stuck when it is unfolded.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
