As shown in fig. 4, a side of the connection passage 251 near the open end of the connection hole 200 is flush with a side of the first hole 211 near the open end of the connection hole 200;
the width of the connection passage 251 in the axial direction of the connection hole 200 is greater than or equal to the width of the second portion 122 in the axial direction of the connection hole 200.
After the docking block 120 is snapped into the docking hole 210, the second portion 122 of the docking block 120 partially protrudes from the connecting channel 251, and abuts against the wall of the circumferential hole of the second hole 212 in the circumferential direction, so that the docking block cannot be directly turned to the connecting channel 251, and thus, the docking block 120 can be limited, that is, the docking block 120 cannot be slid into the connecting channel 251 by simply rotating the connecting shaft 100. When sliding the docking block 120 into the connection channel 251, the docking block 120 needs to be moved axially so that the second portion 122 of the docking block 120 can rotate relative to the connection channel 251.
In actual operation, the connecting shaft 100 is moved axially, even if the abutting block 120 compresses the pressing block 261 and compresses the pressing spring 264, the abutting block 120 moves axially while the pressing block 261 moves axially, the connecting shaft 100 is rotated circumferentially until the second portion 122 of the abutting block 120 is opposite to the connecting channel 251, and the abutting block 120 can be smoothly clamped into the communicating channel under the driving of the connecting shaft 100 so as to gradually recede to be flush with the hole wall of the connecting hole 200 under the action of the guiding inclined surface 252.
As shown in fig. 4, the withdrawing mechanism 250 further includes two withdrawing springs 253 symmetrically disposed on the connecting passage 251, the two withdrawing springs 253 being located at both sides of the lead-out slope 252, each withdrawing spring 253 extending in a circumferential direction of the connecting hole 200;
each withdrawing spring 253 has the same radial interval from one end to the other end with the center line of the connecting hole 200, and a portion of each withdrawing spring 253 near the second hole 212 protrudes out of the lead-out slope 252 to abut against the second portion 122.
When the second portion 122 of the docking block 120 is opposite to the connecting channel 251, the connecting shaft 100 is rotated in the circumferential direction, because the second portion 122 is abutted by the partially protruding withdrawing spring 253, the acting force of the circumferential rotation also needs to overcome the action of the withdrawing spring 253, in the process that the docking block 120 moves along the guiding-out inclined surface 252, the second portion abuts against the withdrawing spring 253 first, in the moving process, the second portion gradually breaks away from the action of the withdrawing spring 253 and moves to the guiding-out chute 240 along the guiding-out inclined surface 252, and in other words, in an unexpected situation, the connecting shaft 100 moves in the axial direction to enable the docking block 120 to be opposite to the connecting channel 251, and the. The withdrawing spring 253 is additionally arranged, so that the withdrawing circumferential acting force is increased, the butt joint block 120 is prevented from being withdrawn accidentally, and the withdrawing is controlled more accurately.
As shown in fig. 4, an end of the introduction sliding groove 220 located at the opening end of the connection hole 200 is provided with an introduction bell mouth 230, the introduction bell mouth 230 includes an introduction inclined surface 231, the introduction inclined surface 231 is transitionally connected with the introduction sliding groove 220, and a plane where the introduction inclined surface 231 is located intersects with a center line of the connection hole 200.
When the butting block 120 is not subjected to external force, the butting block is under the action of the clamping spring 111, most of the butting block 120 is positioned outside the mounting hole 112, and the connecting shaft 100 cannot be clamped into the connecting hole 200; before the connecting shaft 100 is clamped into the connecting hole 200, the butt-joint block 120 is aligned to be clamped into the guide-in sliding groove 220, then the connecting shaft 100 is moved, and under the action of the guide-in inclined surface 231, the butt-joint block 120 gradually retracts into the mounting hole 112 until the whole butt-joint block 120 can be clamped into the connecting hole 200 along with the connecting shaft 100.
The whole clamping process is simple and quick to operate.
As shown in fig. 4, the introducing bell 230 further includes introducing surfaces 232 symmetrically disposed at both sides of the introducing inclined surface 231, and the planes of the two introducing surfaces 232 intersect.
An included angle is formed between the planes of the two leading-in surfaces 232, the opening end of the leading-in bell mouth 230 is larger than the opening end of the leading-in chute 220, so that the difficulty of the second part 122 in being clamped into the leading-in chute 220 can be reduced, the difficulty of the second part 122 in being clamped into the leading-in bell mouth 230 can also be reduced, and the second part 122 can be clamped into the leading-in chute 220 by moving along the leading-in bell mouth 230. The efficiency of the installation of the connecting shaft 100 and the connecting hole 200.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
