The height of the second limiting block 212 may be equal to the distance from the bottom surface of the limiting plate 1121 to the top surface of the fixing base 1, so that when the plurality of second limiting blocks 212 are forced upward, each second limiting block 212 may pass through a second arc-shaped gap 1122 above and a first arc-shaped gap 1112 in a corresponding position, so that the plurality of second limiting blocks 212 block the plurality of second arc-shaped gaps 1122 and the plurality of first arc-shaped gaps 1112. And after plugging, the top surface of the second stopper 212 may be coplanar with the top surface of the fixing base 1.
In a possible implementation manner, the elastic member 22 may be any reasonable structure, for example, the elastic member 22 may be a spring or the like, which is not limited in the embodiments of the present application.

The top end of the second cylindrical section 32 is connected with the bottom end of the first cylindrical section 31, and the outer diameter of the first cylindrical section 31 is larger than that of the second cylindrical section 32. In one possible implementation, the first cylindrical section 31 and the second cylindrical section 32 may be coaxially arranged.

The shape and size of the horizontal cross section of the third limiting block 321 are also the same as those of the horizontal cross section of the first arc notch 1112, the height of the third limiting block 321 is equal to the distance from the bottom surface of the first limiting block 1111 to the top surface of the limiting plate 1121, and the distance between the top surface of the third limiting block 321 and the bottom surface of the first cylindrical section 31 is equal to the height of the first limiting block 1111.
Corresponding to the structure setting of foretell locating plate, setting element 3 can carry out following operation when being connected with fixing base 1 through latch fitting 2:
as shown in fig. 9, when the fixing base 1 and the positioning member 3 are not mounted together, the states of the fixing base 1 and the locking member 2 are as follows: under the action of the elastic force of the elastic member 22, the locking piece 21 receives an upward force, so that the top surface of the second circular plate 211 of the locking piece 21 contacts with the bottom surface of the limiting plate 1121, each second limiting block 212 included in the locking piece 21 is respectively located in the second arc-shaped notch 1122 and the first arc-shaped notch 1112 at the corresponding position of the second limiting block, that is, the second limiting block 212 blocks the first arc-shaped notch 1112 and the second arc-shaped notch 1122, and the top surface of the second limiting block 212 is coplanar with the top surface of the fixing base 1.
When the positioning element 3 and the fixing seat 1 are installed together, a worker can hold the first cylindrical section 31 by hand, the positions of the third limiting blocks 321 are opposite to the positions of the first arc-shaped notches 1112, and then the third limiting blocks 321 are pressed into the first arc-shaped notches 1112, because the second limiting blocks 212 are arranged in the first arc-shaped notches 1112 at the moment, the top ends of the second limiting blocks 212 can be pressed by the bottom ends of the third limiting blocks 321, the second limiting blocks 212 are pressed downwards, the elastic elements 22 are compressed, the second limiting blocks 212 are pressed to the top surfaces of the second limiting blocks 212 and the top surfaces of the limiting plates 1121 in a coplanar manner, namely the second limiting blocks 212 are pressed to the top surfaces of the second limiting blocks 212 without protruding out of the positions of the second arc-shaped notches 1122. At this time, the second cylindrical section 32 is located in the first mounting hole section 111, and each second stopper 212 is located below one first arc-shaped notch 1112.
Then, the worker can hold the first cylindrical segment 31 to rotate, and rotate the third limiting block 321 from the position below the first arc notch 1112 to the position below the first limiting block 1111, because the height of the third limiting block 321 is equal to the distance from the bottom surface of the first limiting block 1111 to the top surface of the limiting plate 1121, the third limiting block 321 is limited between the first limiting block 1111 and the limiting plate 1121 in the height direction.
And because the third limiting block 321 no longer has a pressing effect on the second limiting block 212, the second limiting block 212 rises to be located in the first arc notch 1112 under the upward elastic action of the elastic member 22, and at this time, the second limiting block 212 plays a role in preventing the third limiting block 321 from rotating, so that the third limiting block 321 is limited between the first limiting block 1111 and the limiting plate 1121 in the rotating direction.
At this time, the positioning member 3 is already mounted on the fixing seat, and the first stopper 1111 and the second stopper 212 play a role of preventing the third stopper 321 from falling out of the mounting hole 11.
Adopt this application, can use when the setting element 3 takes place wearing and tearing for a long time, the staff can use the instrument to push down second stopper 212, make the top surface of second stopper 212 and the top surface coplane of limiting plate 1121, at this moment, second stopper 212 no longer has limiting displacement to third stopper 321, the staff can directly rotate setting element 3, rotate third stopper 321 to the position department of first arc breach 1112 below by the position of first stopper 1111 below, then take out third stopper 321 from first arc breach 1112, thereby accomplished the quick dismantlement between setting element 3 and fixing base 1, and at this in-process, need not to take off fixing base 1 from stamping die, thus, the position accuracy of fixing base 1 on stamping die has been guaranteed.
Moreover, when the positioning piece 3 is worn, only the positioning piece 3 needs to be replaced, and the fixing seat 1 and the locking piece 2 do not need to be replaced, so that the cost is saved, and the working efficiency is improved.
In a possible implementation manner, the distance between the top surface of the third stopper 321 and the bottom surface of the first cylindrical section 31 is equal to the height of the first stopper 1111, so that when the third stopper 321 is limited between the first stopper 1111 and the limiting plate 1121, the bottom surface of the first cylindrical section 31 contacts the top surface of the fixing base 1, thereby fixing the positioning member 3 on the top surface of the fixing base 1. In this case, in order to facilitate the worker to press the second stopper 212 downward when detaching the positioning member 3, a plurality of notches 311 may be disposed at the bottom of the first cylindrical section 31, and the positions of the notches 311 and the positions of the third stoppers 321 are staggered, so that when the worker needs to press the second stopper 212 downward, the worker may extend a tool into the notches 311 to contact the second stopper 212 and press it downward.
