[0028] As Figures 1 to 9 shown, an auxiliary device for ruler measurement includes a ruler 1, an auxiliary part 2, and a locking assembly 3.

[0029] Further, the ruler 1 is provided with a through groove and a hemispherical groove, and is provided with a straight line scale arranged along the length direction, used for measuring the length of a line segment.

[0030] Further, the auxiliary part 2 is provided with a positioning groove 21, and the ruler 1 is arranged in the positioning groove 21.

[0031] The auxiliary part 2 is provided with a longitudinal level 22, and the level 22 is arranged perpendicularly to the ruler 1.

[0032] The auxiliary part 2 is provided with a holding part 23, which is used for providing a holding position.

[0033] One end of the auxiliary part 2 is provided with a perpendicular plane perpendicular to the ruler 1, which is used for abutting against a measured object.

[0034] The positioning groove 21 is provided with a square groove and a slot hole, one end of the square groove is provided with a connecting hole, and the connecting hole is arranged in a turning manner.

[0035] Further, the locking assembly 3 is used for fixing the ruler 1 and the auxiliary part 2.

[0036] The locking assembly 3 includes a limiting block 31 and a locking ball 32, the limiting block 31 is used for cooperating with the through groove, the locking ball 32 is used for cooperating with the hemispherical groove, the limiting block 31 is provided with a first reset spring 33, and the locking ball 32 is provided with a second reset spring 34.

[0037] The top of the limiting block 31 is a slope, the limiting block 31 is slidingly arranged in the square groove, one end of the limiting block 31 is provided with a pull rope 35, the pull rope 35 is slidingly arranged in the connecting hole, one end of the pull rope 35 is provided with a pull ring 36, the top of the limiting block 31 is provided with a slope, when the ruler 1 is combined with the auxiliary part 2, the ruler 1 moves into the positioning groove 21, the bottom of the ruler 1 first contacts the slope of the limiting block 31, the limiting block 31 is forced to move into the square groove, at this time, the combination of the two can be realized without the operator exerting additional force (i.e. pulling the pull ring 36) on the limiting block 31 during the combination;

[0038] The first reset spring 33 is arranged in the square groove, and the first reset spring 33 is used to provide a reset force to the limiting block 31;
