Understandably, the first lock core 23222 and the second lock core 23223 are both fixed in the second lock seat 23225, and a part of the first lock core 23222 and the second lock core 23223 can extend into the first recess 232241.

[0061] The first recess 232241 is provided with a first lock connecting part 232242 and a second lock connecting part 232243 on the opposite two inner side walls, respectively. The first lock core 23222 is provided with a third lock connecting part 232221 adapted to the first lock connecting part 232242, and the second lock core 23223 is provided with a fourth lock connecting part 232231 adapted to the second lock connecting part 232243. Understandably, the first lock connecting part 232242 and the third lock connecting part 232221 can be a clamping part and a plug-in groove matched with each other, a lock hook matched with each other, etc. The second lock connecting part 232243 and the fourth lock connecting part 232231 can be a clamping part and a plug-in groove matched with each other, a lock hook matched with each other, etc.

[0062] When the lock pin 2321 is inserted into the lock hole 23221, the first lock joint 232242 is clamped with the third lock joint 232221, and the second lock joint 232243 is clamped with the fourth lock joint 232231; specifically, during the process of inserting the lock pin 2321 into the lock hole 23221, the lock pin 2321 drives the first lock core 23222 and the second lock core 23223 to rotate towards the direction away from the lock hole 23221, until the first lock joint 232242 is clamped with the third lock joint 232221, and the second lock joint 232243 is clamped with the fourth lock joint 232231; at this time, the first lock core 23222 is fixed on the jig seat 21 through the rotating shaft, and the first lock core 23222 also connects the jig cover 22 through the first lock joint 232242 and the third lock joint 232221 clamped with each other; similarly, the second lock core 23223 is fixed on the jig seat 21 through the rotating shaft, and the second lock core 23223 also connects the jig seat 21 through the second lock joint 232243 and the fourth lock joint 232231 clamped with each other, so that the locking mechanism 23 can play a role of locking the jig cover 22 and the jig seat 21.

[0063] When the lock pin 2321 exits the lock hole 23221, the first lock joint 232242 is separated from the third lock joint 232221, and the second lock joint 232243 is separated from the fourth lock joint 232231. Specifically, when the lock pin 2321 exits the lock hole 23221, the first lock joint 232242 is separated from the third lock joint 232221, and the second lock joint 232243 is separated from the fourth lock joint 232231, so that the jig cover 22 and the jig seat 21 will be in an unlocked state, and then the disassembly work between the jig cover 22 and the jig seat 21 can be completed. In this embodiment, the locking mechanism 23 has simple structure, low manufacturing cost and convenient operation.

[0064] In an embodiment, as shown in Figure 7 The locking assembly 232 further includes a second elastic member 2323 and a third elastic member 2324, which are both installed in the first groove 232241; one end of the second elastic member 2323 is in abutment with the first lock core 23222 away from the second lock core 23223, and one end of the second elastic member 2323 is in abutment with the second lock core 23223 away from the second lock core 23223; it can be understood that the second elastic member 2323 and the third elastic member 2324 include but are not limited to springs, elastic pins, etc.

[0065] When the lock pin 2321 is withdrawn from the lock hole 23221, the second elastic member 2323 drives the first lock core 23222 to rotate so that the first lock joint 232242 is separated from the third lock joint 232221, and the third elastic member 2324 drives the second lock core 23223 to rotate so that the second lock joint 232243 is separated from the fourth lock joint 232231. Specifically, when the lock pin 2321 is inserted into the lock hole 23221, the first lock core 23222 compresses the second elastic member 2323, and the second lock core 23223 compresses the third elastic member 2324; when the lock pin 2321 is withdrawn from the lock hole 23221, the rebound force of the second elastic member 2323 drives the first lock core 23222 to rotate until the first lock joint 232242 is separated from the third lock joint 232221, and the rebound force of the third elastic member 2324 drives the second lock core 23223 to rotate until the second lock joint 232243 is separated from the fourth lock joint 232231. In the embodiment, the design of the second elastic member 2323 and the third elastic member 2324 improves the convenience and stability of unlocking the locking mechanism 23.
