[0027] See also Figure 1-3 The specifications of the fixing column 10 and the fixing hole 4 match each other, and the fixing column 10 and the fixing hole 4 are slidably connected. The fixing column 10 cooperates with the fixing hole 4 to fix the parts clamped by the clamping plate 3. The baffle 9 and the fixing sleeve 5 are consistent in size, and the baffle 9 and the fixing sleeve 5 are slidably connected. The baffle 9 drives the fixing column 10 to move into the fixing sleeve 5 to release the limit. There are two groups of fixing sleeves 5 in total, and the two groups of fixing sleeves 5 are evenly distributed on the surface of the clamping plate 3. The setting of multiple groups of fixing sleeves 5 makes the clamping plate 3 more firmly fixed.

[0028] Embodiment 2

[0029] See also Figure 4-6 , positioning holes 11 are provided on both sides of the connecting block 2, and a hole 13 is provided on one side of the shell 1 close to the positioning hole 11, and a spring B14 is fixedly installed inside the hole 13, and a support plate 15 is fixedly installed on one end of the spring B14 close to the positioning hole 11, and a positioning bead 16 is fixedly installed on the end of the support plate 15 away from the spring B14. When the clamping plate 3 is damaged, it can be disassembled and replaced. The positioning hole 11 is hemispherical, and the specifications of the positioning hole 11 and the positioning bead 16 match. The positioning bead 16 and the positioning hole 11 are snap-connected, and the positioning bead 16 cooperates with the positioning hole 11 to connect the shell 1 and the connecting block 2 together. The positioning holes 11 are evenly distributed on the surface of the connecting block 2, and the support plate 15 is slidably connected to the hole 13. Multiple positioning holes 11 have a better positioning effect on the connecting block 2.

[0030] Working principle: When in use, first pull the pull plate 6 outward, and then insert the parts to be inserted between the clamping plates 3, release the pull plate 6, and the rebound force of the spring A8 pushes the baffle 9, and the baffle 9 drives the fixing column 10 to reset and insert the fixing column 10 into the fixing hole 4 for fixation. When disassembling, pull the pull plate 6 outward, and the connecting rod 7 drives the baffle 9 to pull the fixing column 10 out of the fixing hole 4. The parts can be taken out by releasing the limit, and there is no need to use tools such as wrenches, which improves work efficiency. At the same time, when the clamping plate 3 is damaged, it can be disassembled and replaced. It only needs to pull the connecting block 2 outward, and the connecting block 2 drives the positioning bead 16 to move. The positioning bead 16 is under pressure and shrinks toward the inside of the hole 13. The limit on the positioning hole 11 can be released, and the clamping plate 3 can be removed, and then the new connecting block 2 can be aligned with the connecting groove 12 and inserted to replace the new clamping plate 3, which is convenient for replacement and maintenance and improves practicality.
