The first side wall surface 21 extends straight, the first measuring end surface 31 and the second measuring end surface 32 extend straight, and the first measuring end surface 31 and the second measuring end surface 32 are parallel to the first side wall surface 21. The distance from the first measuring end surface 31 to the first side wall surface 21 is greater than the distance from the second measuring end surface 32 to the first side wall surface 21.
Based on practical application conditions, the distance from the first measuring end face 31 to the first side wall face 21 is set to be 69.3mm, and the distance is the upper limit value of the length measured by the workpiece; the distance from the second measuring end face 32 to the first side wall face 21 is set to 68.3mm, which is the lower limit value of the length measured by the workpiece.
The second limiting wall 4 forms a second side wall surface 41 which is arranged in a straight extending way towards one side of the middle limiting wall 3; a third measuring end surface 33 and a fourth measuring end surface 34 which are arranged in a straight extending way are formed on the side of the middle limiting wall 3 facing the second limiting wall 4, and the distance between the third measuring end surface 33 and the fourth measuring end surface 34, which is opposite to the second side wall surface 41, has a second distance difference; the third measuring end surface 33 and the fourth measuring end surface 34 form a second abutting surface 302 based on a second distance difference.
