Compared with the limit of a single locking piece 311 for keeping the quick-mounting plate 200 and the quick-mounting seat 100, the two locking pieces 311 respectively arranged at two sides of the quick-mounting seat 100 keep the limit of the quick-mounting plate 200 and the quick-mounting seat 100, so that the small-angle deflection of the quick-mounting plate 200 or the quick-mounting seat 100 can be prevented, and the limit is more stable. It should be understood that in other embodiments, the two limiting assemblies 310 may not be disposed at positions that can extend into the sliding groove 110, so long as the two limiting assemblies 310 can limit the position of the quick-mounting plate 200 and the quick-mounting seat 100, which is within the scope of the present utility model.

Further, referring to fig. 3 and fig. 4 in combination, in an embodiment, the driving structure 300 further includes a middle block 330 connected to the two locking members 311, the middle block 330 is configured to enable the two locking members 311 to move synchronously, the middle block 330 is provided with an inclined plane 331, the inclined plane 331 is inclined to the moving direction of the locking members 311, the unlocking component 320 includes a key 321 and a second elastic member 322, two opposite ends of the second elastic member 322 are respectively connected to the quick-mounting base 100 and the key 321, the number of the keys 321 is one, and one end of the key 321 close to the middle block 330 abuts against the inclined plane 331. The single key 321 can be pressed to overcome the elastic force of the second elastic element 322 and move along the inclined plane 331, so as to drive the middle block 330 to drive the two locking elements 311 to move simultaneously until the two locking elements 311 retract inside the quick-mounting seat 100, and at this time, the quick-mounting plate 200 can be detached from the quick-mounting seat 100. When the user uses the fast-assembling subassembly 10, only need press button 321 just can release the locating part 311 to the quick-assembling board 200 and the fast-assembling seat 100, compare CN212004834U discloses a cloud platform quick-assembling board is from ejecting structure need rotate locking button several circles unblock, and is more quick convenient.

In an embodiment, the driving structure 300 does not include the middle block 330, the number of the limiting assemblies 310, the limiting slots 220 and the unlocking assemblies 320 are two, the positions of the limiting assemblies 310, the limiting slots 220 and the unlocking assemblies 320 are corresponding to each other, the two unlocking assemblies 320 are used for respectively controlling the two locking members 311, each locking member 311 is provided with an inclined plane 331, each unlocking assembly 320 includes a key 321 and a second elastic member 322, one end of each key 321, which is close to the corresponding locking member 311, is respectively abutted to the corresponding inclined plane 331, each key 321 can independently drive one corresponding locking member 311 to move, and the two keys 321 are pressed simultaneously to respectively drive the two locking members 311 to be separated from the corresponding limiting slots 220, so that the quick assembly board 200 can be detached from the quick assembly seat 100. In the long-term use of the quick assembly 10, the situation that the key 321 is touched by mistake is unavoidable, because the two keys 321 respectively and individually control the corresponding locking piece 311, when a certain key 321 is touched by mistake, the limit of the limit assembly 310 corresponding to the key 321 to the quick assembly 200 and the quick assembly holder 100 can only be released, and the limit of the other limit assembly 310 is not cancelled. Therefore, in the use process of the quick assembly 10, the double keys 321 respectively and independently control the corresponding limiting assemblies 310, so as to effectively avoid misunlocking between the quick assembly plate 200 and the quick assembly seat 100 caused by mistouching, and achieve the effect of preventing mistouching. It should be understood that, in other embodiments, the number of unlocking components 320 may be more than three, the number of limiting components 320 and the number of limiting slots 220 correspond to the number of unlocking components 320 and the positions correspond to each other, regardless of the use experience. Or when the false touch preventing effect is not considered, the number of the unlocking components 320 is one, and the number of the limiting components 310 and the limiting grooves 220 are 1 and the positions of the limiting components and the limiting grooves correspond to each other.
