As an improvement of the utility model, the joint rear end and the front end cover pass through threaded connection.

The utility model has the advantages that:

1. the injection device is small and portable;

2. the use and the operation are simple and convenient;

3. the screw thread type mechanical structure has large injection pressure, is not easy to damage, and is safe and reliable;

4. the application range is wide, various joints can be replaced according to requirements, the application range is wide, and the limitation is small;

5. the sealing ring can be replaced automatically, and the maintenance cost is low;

6. the improved expansibility is strong, and the nut can be welded at the rear part of the rotating handle, and the electric wrench is used for injecting glue.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is an exploded view of the sealant injection device of the present invention.

List of reference numerals:

1. the device comprises a push disc, 2 a manual screw, 3 a front end cover, 4 a cavity, 5 a rear end cover, 6 a connector, 7 a wool felt, 8 a sealing ring, 9 a locking nut, 10 a through hole, 11 a square groove, 12 a small connecting rod, 13 and a handle.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention.
