[0017] 2. In this invention, when disassembling the second groove plate, a ratchet wrench is used to rotate the rod by locking it onto the screw head. The rotation of the rod causes the slide plate to move. Driven blocks are fixedly connected to both sides of the slide plate. The movement of the slide plate causes the driven blocks to slide inside the groove, thereby facilitating the slide plate to move away from the pressure plate. Then, the rear arm plate pushes the connector to move. The movement of the connector loosens the side plate on the docking post from the second groove plate. Then, the docking post is rotated to move the side plate out of the T-slot, thereby facilitating the disassembly of the second groove plate. Attached Figure Description

[0024] In one embodiment of this invention, the assembly includes a slot 2 formed on the bottom surface of the first slot plate 101. A locking post 201 is fitted inside the slot 2. The bottom end of the locking post 201 is fixedly connected to a base 102 in a horizontal position. A horizontal plate 202 is fixedly connected to the top end of the locking post 201 in a horizontal position. Limiting posts 203 are fixedly connected vertically to both ends of the horizontal plate 202. A slide rail 204 is fixedly connected to the inner wall of the first slot plate 101 in a horizontal position. A slider 205 is slidably connected to the slide rail 204. A locking block 206 is fixedly installed on the surface of the slider 205. A pair of L-shaped grooves 207 are formed on the surface of the locking block 206. The limiting posts 203 are fitted inside the L-shaped grooves 207. A docking seat 3 is fixedly connected to one side of the surface of the slider 205. A crossbar 301 is fixedly connected to the horizontal position of the docking seat 3. One end of the crossbar 301 extends toward the middle of the first groove plate 101.

[0025] Specifically, when the base 102 needs to be disassembled, the clamping block 303 has an arc-shaped groove 305. The arc-shaped groove 305 is attached to the edge of the cam 307 by the elastic force of the first spring 304. The rotation of the handle 308 drives the cam 307 to rotate through the rotating rod 306, so that the clamping block 303 can retract by the elastic force of the first spring 304. A crossbar 301 is fixedly connected to one side of the clamping block 303. The crossbar 301 moves by the movement of the clamping block 303. The other end of the crossbar 301 is fixedly connected to the docking seat 3, and the docking seat 3 is fixedly installed on the slider 205. The movement of the crossbar 301 drives the slider 205 to slide on the slide rail 204 through the docking seat 3. The movement of the slider 205 drives the locking block 206 to move, so that the limiting post 203 disengages from the interior of the L-shaped groove 207, thus facilitating the disassembly of the base 102.
[0026] In one embodiment of this invention, the docking assembly includes a limiting plate 4 fixedly installed on the inner wall of the second groove plate 104. T-slots 401 are formed at both ends of the second groove plate 104. A docking post 402 is fitted inside the T-slots 401. A side plate 403 is fixedly connected to one end of each docking post 402. Pins 404 are fixedly connected to both ends of the side plate 403 near the T-slots 401, and are fitted inside the T-slots 401. A mating joint 405 is fixedly connected to the other end of each docking post 402.

A sliding groove 408 is provided on the arm plate 407. A pressure plate 409 is fixedly connected to the other end of the arm plate 407. A rod 410 is movably inserted into the pressure plate 409. A screw head 411 is fixedly installed at the middle position of the rod 410. External threads are provided on the surfaces of both ends of the rod 410. A sliding plate 412 is threadedly connected to both ends of the rod 410. A driven block 413 is fixedly connected to both ends of the sliding plate 412. The driven block 413 is slidably connected inside the sliding groove 408. A second spring 414 is sleeved on the rod 410. The two ends of the second spring 414 are respectively in contact with one side of the sliding plate 412 and one side of the pressure plate 409.
[0027] Specifically, when disassembling the second slot plate 104, a ratchet wrench is used to rotate the rod 410 by engaging the screw head 411. The rotation of the rod 410 causes the slide plate 412 to move. Driven blocks 413 are fixedly connected to both sides of the slide plate 412. The movement of the slide plate 412 causes the driven blocks 413 to slide inside the slide groove 408, thereby facilitating the slide plate 412 to move away from the pressure plate 409. Then, the arm plate 407 pushes the connector 405 to move. The movement of the connector 405 loosens the side plate 403 on the docking post 402 from the second slot plate 104. Then, the docking post 402 is rotated to move the side plate 403 out of the T-slot 401, thereby facilitating the disassembly of the second slot plate 104.
[0028] The working principle of this invention is as follows: When the base 102 needs to be disassembled, the clamping block 303 has an arc-shaped groove 305. The arc-shaped groove 305 is attached to the edge of the cam 307 by the elastic force of the first spring 304. The rotation of the handle 308 drives the cam 307 to rotate through the rotating rod 306, thereby facilitating the retraction of the clamping block 303 by the elastic force of the first spring 304. A crossbar 301 is fixedly connected to one side of the clamping block 303. The movement of the clamping block 303 causes the crossbar 301 to move. The other end of the crossbar 301 is fixedly connected to the docking seat 3, and the docking seat 3 is fixedly installed on the slider 205. The movement of the crossbar 301 drives the slider 205 to slide on the slide rail 204 through the docking seat 3. The movement of the slider 205 drives the locking block 206 to move, thereby disengaging the limiting post 203 from the interior of the L-shaped groove 207, thus facilitating the disassembly of the base 102.
[0029] When disassembling the second slot plate 104, a ratchet wrench is used to rotate the rod 410 by engaging the screw head 411. The rotation of the rod 410 causes the slide plate 412 to move. Driven blocks 413 are fixedly connected to both sides of the slide plate 412. The movement of the slide plate 412 causes the driven blocks 413 to slide inside the slide groove 408, thereby facilitating the slide plate 412 to move away from the pressure plate 409. Then, the arm plate 407 pushes the connector 405 to move. The movement of the connector 405 loosens the side plate 403 on the docking post 402 from the second slot plate 104. Then, the docking post 402 is rotated to move the side plate 403 out of the T-slot 401, thereby facilitating the disassembly of the second slot plate 104.
