In some embodiments, the driving bar 34 is a flat bar, two opposite first bar-shaped through holes 22 are formed in the peripheral wall of the abutting member 20, the first bar-shaped through holes 22 extend in the axial direction of the mounting hole 21, a through groove 41 opposite to the first bar-shaped through hole 22 is formed in the positioning member 40, the through groove 41 extends towards the bottom end of the positioning member 40, the flat bar sequentially passes through one first bar-shaped through hole 22, the through groove 41 and the other first bar-shaped through hole 22, the two first bar-shaped through holes 22 are located between the first end D and the second end of the flat bar, and the length of the first bar-shaped through hole 22 is greater than the width of the flat bar; the part of the flat strip in the mounting hole 21 is provided with an inclined strip-shaped through groove 341, one end of the strip-shaped through groove 341, which is far away from the bottom end of the connecting seat 100, is close to the first end D of the driving strip 34, a pin shaft 35 which can slide along the strip-shaped through groove 341 is arranged in the strip-shaped through groove 341 of the first end D, and two ends of the pin shaft 35 are respectively connected to two sides of the through groove 41. Wherein the length of the first through-bar-shaped hole 22 is greater than the width of the flat bar, so that the abutting member 20 moves in extension or retraction, and the flat bar moves relative to the first through-bar-shaped hole 22 without interference of the abutting member 20.
In this embodiment, the principle of the driving bar 34 controlling the positioning element 40 to extend and retract is specifically as follows: when the first end D of the driving strip 34 is pressed inward, the strip-shaped through groove 341 moves toward the second end of the driving strip 34, so as to generate an upward acting force on the pin shaft 35, so that the pin shaft 35 slides upward along the strip-shaped through groove 341, and drives the positioning member 40 to move upward (i.e., retract) along the mounting hole 21; when the first end D of the driving strip 34 is released, the driving strip 34 is reset under the action of the second elastic piece, the strip-shaped through groove 341 moves towards the first end D of the driving strip 34 to generate a downward component acting force on the pin shaft 35, so that the pin shaft 35 slides downwards along the strip-shaped through groove 341 to drive the positioning part 40 to move downwards along the mounting hole 21 so as to extend out of the bottom end of the connecting seat 100.
It should be noted that, in the present embodiment, the mounting hole 21 is a circular hole and the positioning element 40 is a cylindrical element, but in other embodiments, the mounting hole 21 may be a hole with other shapes such as a square hole, an elliptical hole, a polygonal hole, etc., and the corresponding positioning element 40 may be a square cylindrical element, an elliptical cylindrical element, a polygonal cylindrical element, etc.

The two ends of the pin shaft 35 are clamped in the two second strip-shaped through holes 23 respectively, so that the two ends of the pin shaft 35 are guided in a sliding manner, and the pin shaft 35 is ensured to drive the positioning piece 40 to move up and down in the mounting hole 21 more stably and smoothly.
In some embodiments, the driving bar 34 extends along the axial direction of the camshaft 31, the first end D of the driving bar 34 and the shaft seat 33 are located on the same side of the connecting seat 100, the camshaft 31 is fixedly connected with the shaft seat 33, the outer end of the shaft seat 33 is provided with a crank 36, the inner side surface of the free end of the crank 36 is an inclined surface S (i.e., the inner side surface of the free end of the crank 36 faces the first end D of the driving bar 34), and the inclined surface S is connected with the end surface edge of the first end D of the driving bar 34. In this embodiment, when the camshaft 31 is rotated by holding the adjusting member 32, the shaft seat 33 is rotated synchronously, i.e. the crank 36 is driven to rotate synchronously; when the cam shaft 31 is rotated in the first direction by the hand-held adjusting member 32 to retract the tightening member 20 upward, the free end of the crank 36 moves toward the first end D of the driving bar 34, and the inclined surface S of the free end gradually presses the first end D of the driving bar 34 inward to gradually retract the positioning member 40 upward; when the cam shaft 31 is rotated by the hand-held adjusting member 32 in the opposite direction of the first direction to extend the abutting member 20 downward, the free end of the crank 36 is separated from the first end D of the driving bar 34, the inclined surface S of the free end cancels the extrusion force on the first end D of the driving bar 34, and the first end D of the driving bar 34 is reset under the elastic force of the second elastic member to extend the positioning member 40 downward. The embodiment realizes that the extending and retracting of the abutting piece 20 and the positioning piece 40 are simultaneously controlled through the adjustment of the handheld adjusting piece 32, so that the dismounting operation of the quick-release connecting piece and the chute interface 200 is simpler and more convenient. More specifically, the crank 36 protrudes along the radial direction of the shaft seat 33, and the inclined plane S may be a plane or an arc, and the inclined plane S extends along the protruding direction of the crank 36, and is inclined and inclined towards the direction away from the driving strip 34; or the inclined plane S encloses a hook groove, the inclined plane S at the free end gradually presses the first end D of the driving bar 34 inwards to the first end D of the driving bar 34 to be accommodated in the hook groove enclosed by the inclined plane S, the outer side surface of the first end D of the driving bar 34 abuts against the side wall of the hook groove enclosed by the inclined plane S, the free end of the inclined plane S is separated from the outer side surface of the first end D of the driving bar 34, and the inclined plane S is prevented from hooking the first end D of the driving bar 34 when the camshaft 31 is rotated in the opposite direction of the first direction by holding the adjusting member 32.
In some embodiments, the end surface of the first end D of the driving bar 34 is an inclined end surface or a curved surface, the end surface of the first end D is disposed at an angle with respect to the radial cross section of the shaft seat 33, and the crank 36 contacts with the end surface of the first end D when rotating, so as to press or release the driving bar 34 to drive the driving bar 34 to move.
