DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , a wind shield for garden seedlings in this embodiment includes a cover body 1, a support assembly 2 is provided on the cover body 1, and a clamping mechanism 3 is provided inside the cover body 1.

[0023] The clamping mechanism 3 includes a fixed box 304, a clamping block 312, a limiting sleeve 313 and a telescopic rod 302. A fixed box 304 is horizontally arranged in the cover body 1, and both sides of the fixed box are fixed to the inner side wall of the cover body 1. Two sliding rods 305 are fixed in the fixed box 304. A sliding sleeve 306 is slidably mounted on the sliding rod 305. One side of the sliding sleeve 306 is fixed with a connecting plate 303, and one side of the connecting plate 303 is fixed with a clamping plate 301. Opposite sides of the two sliding sleeves 306 are fixed with racks 311. A rotatable rotating shaft 309 is horizontally arranged in the fixed box 304, and a gear 310 meshing with the rack 311 is fixed on the rotating shaft 309.

[0024] A positioning wheel 307 is fixed on the rotating shaft 309. A plurality of limiting grooves 314 are annularly formed on the circumferential side wall of the positioning wheel 307. A clamping block 312 is snap-fitted in one of the plurality of limiting grooves 314, which is convenient for limiting the rotating shaft 309. A limiting sleeve 313 is sleeved on the outer wall of the clamping block 312.

[0025] First, the cover body 1 is covered on the seedlings. At this time, the seedlings are placed inside the cover body 1. Then, the hand wheel 308 is rotated to drive the rotating shaft 309 to rotate. Then, the rotating shaft 309 drives the gear 310 to rotate. The two sides of the gear 310 are engaged with the racks 311, so as to drive the two sliding sleeves 306 to move relatively, so that the sliding sleeves 306 drive the connecting plate 303 and the clamping plate 301 to move. Then, the clamping plate 301 abuts against the seedlings, so as to support the seedlings.

[0026] Wherein, telescopic rods 302 are fixed on both inner walls of the cover body 1, and one end of each telescopic rod 302 is fixed to the connecting plate 303, which increases the stability when the moving plate moves.

[0027] At the same time, the clamping plate 301 is located outside the fixed box 304. A hand wheel 308 is fixed at one end of the rotating shaft 309, which is convenient for the staff to rotate the rotating shaft 309.

[0028] Please refer to Figure 1 , the support assembly 2 in this embodiment includes a threaded rod 201 and a threaded sleeve 202. Threaded sleeves 202 are arranged on both sides of the cover body 1. Threaded rods 201 are threadedly connected to both ends of the threaded sleeve 202. The thread grooves at both inner ends of the threaded sleeve 202 have opposite threads, so that the two threaded rods 201 can be simultaneously retracted into the inner side of the threaded sleeve 202 and extended outward.

[0029] The two threaded rods 201 are arranged vertically. One end of the upper threaded rod 201 is hinged to the outer side wall of the cover body 1. One end of the lower threaded rod 201 is hinged to a fixing plate 203, and a plurality of positioning rods 204 are fixed to the lower end of the fixing plate 203.

[0030] By rotating the threaded sleeve 202, the threaded sleeve 202 drives the threaded rods 201 on both sides to extend outward, so that the positioning rods 204 on the fixing plate 203 contact the ground, enabling the positioning rods 204 to be inserted into the ground to support the cover body 1.

[0031] Among them, the positioning rods 204 are evenly distributed on the fixing plate 203, facilitating the stable fixation of the fixing plate 203 on the ground.

[0032] The working principle of the above embodiment is as follows:

[0033] First, cover the cover body 1 on the seedlings. At this time, the seedlings are placed inside the cover body 1. Then, rotate the handwheel 308 to drive the rotation of the rotating shaft 309, and then drive the rotation of the gear 310 through the rotating shaft 309. The two sides of the gear 310 are engaged with the racks 311, thereby driving the relative movement of the two sliding sleeves 306, causing the sliding sleeves 306 to drive the connecting plate 303 and the clamping plates 301 to move. Then, the clamping plates 301 move closer to both sides of the seedlings, and then the inner sides of the clamping plates 301 abut against the seedlings to support the seedlings.

[0034] Subsequently, slide the block 312 into one of the plurality of limiting grooves 314 inside the limiting sleeve 313 to fix the positioning wheel 307 and the handwheel 308, which can lock the retraction of the insertion rod.

[0035] Then, by rotating the threaded sleeve 202, the threaded sleeve 202 drives the threaded rods 201 on both sides to extend outward, so that the positioning rods 204 on the fixing plate 203 contact the ground, enabling the positioning rods 204 to be inserted into the ground to support the cover body 1, ensuring the growth effect of the seedlings.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
