A connecting sleeve 25 is provided in the receiving groove 203, and a connecting through hole 251 is provided in the connecting sleeve 25. Two pin shafts 23 are respectively located at both ends of the connecting through hole 251.

[0023] The two bases 2 are connected to the two mounting grooves 10 respectively, and the axis of the shaft hole 101, the axis of the functional hole 201 and the axis of the connecting through hole 251 are in the same straight line, and the shaft hole 101 is connected to the functional hole 201. After the pin 23 slides toward the shaft hole 101, at least a portion of one end of the pin 23 protrudes out of the functional hole 201 and is located in the shaft hole 101, and the other end of the pin 23 is inserted into the connecting through hole 251. After the connecting through hole 251, the other end of the pin 23 is guided, so that the axial sliding of the pin 23 is more stable.

[0024] The base 2 is provided with a plug hole 202 connected to the functional hole 201, the axis of the plug hole 202 is perpendicular to the axis of the functional hole 201, and a top block 24 is inserted into the plug hole 202, and the top block 24 is located at the end of the limiting protrusion 231 away from the shaft hole 101. The functional hole 201 is a countersunk hole, the small hole of the countersunk hole is close to the shaft hole 101, and the limiting protrusion 231 abuts against the step surface of the countersunk hole. The countersunk hole limits the sliding of the pin shaft 23 toward the shaft hole to prevent excessive extension of the functional hole.

[0025] A driving inclined surface 241 which narrows inwards is provided on one side of the top block 24 close to the limiting protrusion 231, and a matching inclined surface 2311 which abuts against the driving inclined surface 241 is provided on the limiting protrusion 231. After such arrangement, when the top block 24 is inserted, the top block 24 can push the pin 23 to move laterally.
