[0010] Preferably, the threaded rod is located directly above the threaded connection hole, and the threaded rod matches the thread inside the threaded connection hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: rust-preventive oil is injected into the inside of the sleeve through the injection hole. The rust-preventive oil enters the inside of the receiving groove through the injection hole. The rubber sealing plate seals the connection plate and the bottom plate. Then, the worker can insert the rubber plug into the inside of the injection hole to complete the upper seal. This structure seals the gauge block through the sleeve, making it more convenient to seal the gauge block. Under the action of the rust-preventive oil, air and moisture are effectively isolated, preventing the gauge block from rusting. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figures 1-4 A base hole position gauge includes a base plate 1, a positioning pin 4 installed at the middle position of the top of the base plate 1, and a base body 6 sleeved on the outside of the positioning pin 4. Multiple positioning holes 12 are opened inside the top of the base plate 1 in front of the positioning pin 4, and a gauge block 2 is provided inside each of the positioning holes 12. It also includes a sleeve 8 that can be sleeved on the outside of the gauge block 2.

[0019] The bottom plate 1 has threaded connection holes 3 on both sides of the top, and a sleeve 8 is provided above the gauge block 2. The top of the sleeve 8 has multiple injection holes 9, and a rubber plug 7 matching the injection hole 9 is provided above the injection hole 9. A connecting plate 10 is installed at the bottom of the sleeve 8, and a rubber sealing plate 11 is provided at the bottom of the connecting plate 10. Threaded rods 5 are provided on both sides of the top of the connecting plate 10, and a storage groove 13 is provided at the bottom of the sleeve 8, the connecting plate 10 and the rubber sealing plate 11.

[0020] Gauge block 2 matches the positioning hole 12, and gauge block 2 matches the storage slot 13;

[0021] The bottom end of the threaded rod 5 passes through the connecting plate 10 and the rubber sealing plate 11 in sequence, and the bottom end of the threaded rod 5 extends to the bottom of the rubber sealing plate 11.

[0022] The bottom end of the injection hole 9 passes through the sleeve 8, and the injection hole 9 is connected to the receiving groove 13.

[0023] The threaded rod 5 is located directly above the threaded connection hole 3, and the threaded rod 5 matches the thread inside the threaded connection hole 3.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this mechanism, rust-preventive oil is injected into the inside of the sleeve 8 through the injection hole 9.
