[0091] In the above-mentioned embodiments, since the lifting platform 43 is located on the side of the fourth end 312 away from the third end 311, when the driving rod 42 drives the lifting platform 43 to approach the slot of the containing groove 11, the lifting platform 43 will move to abut against the fourth end 312 of the third driving slope 31, and the lifting platform 43 will move to abut against the third end 311 of the third driving slope 31 in the direction approaching the containing groove 11; since the third end 311 is located on the side of the fourth end 312 close to the slot of the containing groove 11, and the third end 311 is located on the side of the fourth end 312 close to the containing groove 11, during the movement of the lifting platform 43 to abut against the third end 311 of the third driving slope 31 in the direction approaching the containing groove 11, the clamping piece 3 will move away from the article, so that the clamping piece 3 is moved out of the containing groove 11. And when the driving rod 42 drives the lifting platform 43 to approach the slot of the containing groove 11, the lifting platform 43 will abut against the abutting portion 22 and drive the support plate 2 to approach the slot of the containing groove 11.

[0092] Please refer to Figure 1 In some embodiments, the lifting platform 43 includes a lifting plate 431 and a rolling piece 432, the lifting plate 431 is located on the side of the abutting portion 22 away from the slot of the containing groove 11, and the rolling piece 432 is rotatably arranged on the lifting plate 431; under the driving of the driving rod 42, the lifting plate 431 can abut against the abutting portion 22, and the rolling piece 432 can roll against the third driving slope 31.

[0093] In the above-mentioned embodiments, the rolling piece 432 can roll against the third driving slope 31, which can reduce the friction between the lifting platform 43 and the clamping piece 3. ​

[0094] Please refer to Figure 1 and Figure 2 In some embodiments, the driving mechanism 4 further comprises a first elastic member 47 and a plurality of second elastic members 48, the first elastic member 47 is connected with the housing 1 and the lifting platform 43 respectively; each second elastic member 48 is connected with the housing 1 and a clamping member 3 respectively; wherein, under the driving of the driving rod 42, the lifting platform 43 can drive the support plate 2 to approach the slot of the accommodating groove 11 against the elastic force of the first elastic member 47, and the lifting platform 43 can drive a clamping member 3 to move away from the object against the elastic force of a second elastic member 48.

[0095] Please refer to Figure 1 and Figure 2 The lifting platform 43 is provided in plurality, and the first elastic member 47 is also provided in plurality, and each first elastic member 47 is connected with the housing 1 and a lifting platform 43 respectively, under the driving of the driving rod 42, each lifting platform 43 can drive the support plate 2 to approach the slot of the accommodating groove 11 against the elastic force of a first elastic member 47.

[0096] In the above embodiments, in the initial state, the support part 21 is located in the accommodating groove 11, and the clamping member 3 is horizontally arranged on the side of the support part 21 close to the slot of the accommodating groove 11 (please refer to Figure 1 ). When the driving rod 42 drives the plurality of lifting platforms 43 to approach the slot of the accommodating groove 11, each lifting platform 43 will drive the support plate 2 to move to the position where the support part 21 is flush with the slot of the accommodating groove 11 against the elastic force of the first elastic member 47, and each lifting platform 43 will drive a clamping member 3 to move away from the object against the elastic force of a second elastic member 48, so as to facilitate the placement of the object on the support part 21 or the removal of the object from the support part 21 (please refer to Figure 2 ). When the driving rod 42 drives the plurality of lifting platforms 43 to move away from the slot of the accommodating groove 11, the force exerted by the lifting platform 43 on the first elastic member 47 and the force exerted by the clamping member 3 on the second elastic member 48 will gradually decrease, so that the first elastic member 47 and the second elastic member 48 return to the original state. During the process of the first elastic member 47 and the second elastic member 48 returning to the original state, the first elastic member 47 will exert an elastic force on the lifting platform 43, so that the support part 21 moves away from the slot of the accommodating groove 11 and returns to the position shown in Figure 1 . The second elastic member 48 will exert an elastic force on the clamping member 3, so that the clamping member 3 moves to be horizontally arranged on the side of the support part 21 close to the slot of the accommodating groove 11. By providing the first elastic member 47 and the second elastic member 48, the energy consumption of the driving mechanism 4 can be reduced, and it is also helpful for the support part 21 and the clamping member 3 to return to the initial state after reciprocating movement.
