[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-4 A convenient optometry tool includes a sight mark rod 1, a nose pad 2 for matching with a user's nose bridge is installed at one end of the sight mark rod 1, the nose pad 2 is installed on the sight mark rod 1 through a nose pad handle 3, and a handle 4 convenient for human hand holding is installed at the other end of the sight mark rod 1, so that the user can hold the handle 4 and place the nose pad 2 on the nose bridge to conveniently perform eye optometry operation. Specifically:

[0023] An adjusting block 5 is movably mounted on the sight mark rod 1, an adjusting screw matching the sight mark rod 1 is screwed on the adjusting block 5, a sight mark frame 7 is mounted on the adjusting block 5, a sight mark block 8 is mounted on the sight mark frame 7 via a rotating screw, the rotating screw is screwed on the sight mark frame 7, and the sight mark block 8 is mounted on the rotating screw. The sight mark block 8 is provided with a sight mark for performing vision detection and realizing optometry operation. The sight mark block 8 is installed on the sight mark frame 7 by means of a rotating screw, which not only realizes the installation of the sight mark block 8, but also facilitates the relative rotation between the sight mark block 8 and the sight mark frame 7. The adjustment block 5 is installed on the sight mark rod 1 by means of an adjusting screw, which not only realizes the installation of the adjustment block 5, but also facilitates the relative movement of the adjustment block 5 on the sight mark rod 1, and then the sight mark block 8 can be relatively rotated and moved as needed to better meet the actual optometry needs; preferably, there are two rotating screws, and the two rotating screws are distributed on both sides of the sight mark block 8, which helps to better assist the installation and rotation of the sight mark block 8.
