[0035] The receiving assembly 201 includes a plurality of receiving chambers 201a opened on the top of the carrier plate 101, receiving grooves 201b uniformly opened around the receiving chambers 201a, a pressure spring 201c arranged inside the receiving groove 201b, and a pressure plate 201d arranged at the bottom of the pressure spring 201c; wherein one end of the pressure plate 201d is rotatably connected to the inside of the receiving groove 201b;

[0036] The support assembly 202 includes a support tube 202a disposed inside the accommodating chamber 201a, a guide sleeve 202b fixed inside the support tube 202a, reserved grooves 202c uniformly arranged on the outer periphery of the guide sleeve 202b, and through holes 202d penetrating the outer wall of the support tube 202a, and the through holes 202d are uniformly distributed on the outer wall of the support tube 202a;

[0037] The snap-fit ​​assembly 203 includes a bearing sleeve 203a arranged inside the guide sleeve 202b, a connecting rod 203b evenly distributed on the outer wall of the bearing sleeve 203a, a snap-fit ​​block 203c arranged at the end of the connecting rod 203b, and a guide rail 203d sleeved on the outer wall of the snap-fit ​​block 203c; wherein the connecting rod 203b is hinged to the bearing sleeve 203a, and a guide groove 203e is opened inside the bearing sleeve 203a.

[0038] Specifically, the power assembly 204 includes a fixed rod 204a disposed inside the bearing sleeve 203a, guide rods 204c disposed on both sides of the outer wall of the fixed rod 204a, and a rotating disk 204b disposed at the bottom of the fixed rod 204a, one end of the pressure plate 201d is rotatably connected to the inside of the receiving groove 201b, the other end of the pressure plate 201d is fixedly connected to the pressure spring 201c, the other end of the pressure plate 201d is fixedly connected to the inside of the receiving groove 201b, and the through hole 202d is The shape is matched with the locking block 203c, and the outer shape of the locking block 203c completely coincides with the pressure plate 201d. Two guide grooves 203e are opened inside the bearing sleeve 203a. The guide grooves 203e are spirally distributed on the inner wall of the bearing sleeve 203a. The locking block 203c is slidably connected with the guide rail 203d. The guide rod 204c is arranged inside the guide groove 203e. The guide rod 204c is symmetrical about the center line of the fixed rod 204a and is evenly distributed on both sides of the fixed rod 204a.

[0039] The operation process of this embodiment is as follows: first, 202 is placed inside 201a, and 203 is set inside 202. When 203 enters the inside of 201a, 201c will enter the inside of 203e from the gap below 203e. Since 203e is spiral as a whole, when 204a does not rotate, 203a will move upward as a whole. When 203a moves upward, 203c will be pulled inward to enter the inside of 202a, so that 202a can completely enter the inside of 201a. When 201a completely enters the inside of 201a, When 103 is inside, rotate 204a, and under the action of 204c and 203e, 203a will move downward. When 203a moves downward, 203c will be pushed outward by the action of 203b, and then it will be stuck into the inside of 201b to complete the fixation. Then, under the action of 201c, 201d will press 203c to make the fixation more stable. When 103 needs to be replaced, rotate it in the opposite direction to move 203a upward, and make 203c return to the inside of 202a to complete the disassembly of 103. The whole process facilitates the replacement of 103. Specific embodiment 2

[0040] See also Figure 4 and Figure 5 On the basis of the specific embodiment 1, it also includes a splicing component 300, including a limiting component 301 arranged on one side of the carrier plate 101, and a fixing component 302 arranged inside the limiting component 301. The limiting component 301 includes a first fixing block 301a arranged at the end of one carrier plate 101, a second fixing block 301b arranged at the end of the other carrier plate 101, a limiting groove 301c running through the inside of the second fixing block 301b, and a fixing groove 301d opened at the end of the limiting groove 301c. The fixing component 302 includes a ring 302d arranged inside the first fixing block 301a, a pull rod 302a arranged inside the ring 302d, a fixing block 302b fixed to the end of the pull rod 302a, and a tension spring 302c sleeved on the outside of the pull rod 302a.

[0041] The operation process of this embodiment is: first press 302a to one side to push 302b out of the other end of 301b, then rotate 302a ninety degrees, and then release 302a, and pull 302a back under the action of 302c, so that 302b is stuck in the inside of 301d. Since 302c will be compressed when 302a is pushed to one side, when 302a is released, 302c will generate elastic force to pull 302a back, so that 302b is always stuck in the inside of 301d, thereby completing the fixation of the entire device. After disassembly, the entire device is separated for easy carrying.
