It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, in this embodiment, the thimble 400 is fixed mainly by two parts, the lower part of the thimble 400 is fixed by the fixed block 300, the upper part of the thimble 400 is fixed by the centering mechanism 100, and the two centering mechanisms 100 can release the fixing of the thimble 400 by the lifting of the lifting mechanism 200. The centering mechanism 100 and the fixing block 300 are fixed by a base.

As shown in fig. 2, each centering mechanism 100 includes a first clamping member 110, a second clamping member 120, a guide rod 150, and a pushing mechanism for providing a clamping pushing force, where the first clamping member 110 and the second clamping member 120 are simultaneously slidably connected to the guide rod 150, and the pushing mechanism pushes the first clamping member 110 and the second clamping member 120 to relatively slide along the guide rod 150 to clamp and fix the thimble 400. The first clamping member 110 and the second clamping member 120 are provided with a first clamping opening 111 and a second clamping opening 121 which are opposite, as shown in fig. 3, the first clamping opening 111 and the second clamping opening 121 are both V-shaped openings, the V-shaped openings are relatively combined to form a closed clamping hole 140 which is variable in size and can be inserted into the thimble 400, and the clamping hole 140 is reduced along with the relative movement of the first clamping opening 111 and the second clamping opening 121, so that the thimble 400 is centered and fixed. One structure of the pushing mechanism is shown in fig. 2, and includes a first stopper 161, a first spring 162, a second stopper 171, and a second spring 172, where the first stopper 161 and the second stopper 171 are respectively fixed on the guide rods 150 at two sides of the first clamping member 110 and the second clamping member 120, the first spring 162 is disposed between the first clamping member 110 and the first stopper 161, the second spring 172 is disposed between the second clamping member 120 and the second stopper 171, the first stopper 161 and the second stopper 171 are fixed on a base plate 180, a lower operation opening 181 for allowing the thimble 400 and the lift-up bump 210 to pass through is formed on the base plate 180, and some parts can be shared between the centering mechanisms, as shown in fig. 2, two centering mechanisms share two guide rods 162 and share the first stopper 171.

Releasing the first clamp member 110 and the second clamp member 120 is accomplished by a cooperative action with the jacking mechanism 200. Referring to fig. 3 and 6, the first clamping member 110 has a first lateral pushing inclined surface 112, the second clamping member 120 has a second lateral pushing inclined surface 122, and the first lateral pushing inclined surface 112 and the second lateral pushing inclined surface 122 are opposite to each other to form a jacking slot 190. As shown in fig. 5, a jacking protrusion 210 is provided in the jacking mechanism 200 and is matched with the jacking slot 190, referring to fig. 6 and 7, as the jacking mechanism 200 ascends, the jacking protrusion 210 enters the jacking slot 190, the first lateral pushing inclined surface 112 and the second lateral pushing inclined surface 122 are respectively contacted on both sides of the jacking protrusion 210 and prop the first lateral pushing inclined surface 112 and the second lateral pushing inclined surface 122 open towards both sides, and the first clamping opening 111 and the second clamping opening 121 are released.

The jacking mechanism 200 should avoid contacting with the thimble 400 during jacking, so as to reduce the influence on the thimble 400, for example, a through hole 220 allowing the thimble 400 to pass through should be formed in the jacking mechanism 200, and the diameter of the through hole 220 should be larger than the diameter of the thimble 400.

The jacking function of the jacking mechanism 200 can be realized by the jacking cylinder 230, and the jacking cylinder 230 pushes the jacking mechanism 200 to move up and down.

In order to prevent the spring clamping force from being unbalanced and causing the thimble 400 to be deviated, a stopper 130 may be provided to limit the distance of relative displacement between the first clamping member 110 and the second clamping member 120. For example, fig. 2 employs a stopper 130 directly disposed on a displacement path between the first clamping member 110 and the second clamping member 120 for stopping, and the stopper 130 is fixed on the substrate 180.

In this embodiment, the fixing block 300 for fixing the lower portion of the thimble 400 has a fixing hole, and the tail end of the thimble 400 is inserted into the fixing hole during fixing.
