[0092] A threaded hole is arranged on the left end of the transmission rod 321, and the valve core fixing seat 322 is sleeved on the left end of the transmission rod 321 and can be locked and fixed by a screw. In this way, when the transmission rod 321 or the valve core 33 is damaged or worn, the valve core fixing seat 322 and the transmission rod 321 can be detached from each other, and the damaged parts can be replaced, so that the whole does not need to be removed or replaced, the operation is simpler, the maintenance cost is lower, and the utility is more favorable.

The outer sleeve body 331 is arranged at the upper end of the valve core 33, and the outer sleeve body 331 can be clamped and fixed by the inner top wall and the inner bottom wall of the clamping slot 3221. Thus, the valve core 33 can be connected with the valve core fixing seat 322, and the valve core 33 can be driven to move up and down by the valve core fixing seat 322 to open or close the nozzle 22.

[0095] Advantageously, in some embodiments of the utility model, the top surface of the outer sleeve body 331 is provided with a limiting block 332, and the outer wall of the limiting block 332 is provided with a vertical section 3321.

Specifically, during installation, the glue outlet 21 is inserted into the connecting seat 40 at the bottom of the valve shell 31, the outer sleeve body 331 at the upper end of the valve core 33 is clamped into the clamping slot 3221, and then the locking assembly 50 is used for locking and fixing. Conversely, during disassembly, the glue outlet 21 is unlocked, the glue outlet 21 is pulled out of the connecting seat 40, and the outer sleeve body 331 is pulled out of the valve core fixing seat 322, so that the disassembly is very convenient, which is beneficial to the maintenance or replacement of related parts and use.

[0103] When the lever 51 drives the locking member 53 to rotate to the first position, the locking member 53 is clamped in the arc-shaped locking groove 215 to lock and fix the glue outlet seat 21; when the lever 51 drives the locking member 53 to rotate to the second position, the locking member 53 rotates out of the arc-shaped locking groove 215 to unlock the glue outlet seat 21.

[0104] The outer wall of the locking member 53 is generally in an arc-shaped structure matched with the arc-shaped locking groove 215, and is connected with the lever 51 on the front side wall of the valve shell 31 through the rotating rod 52, so that the locking member 53 can be driven to rotate by rotating the lever 51. Thus, when the lever 51 drives the locking member 53 to rotate to the first position, the outer wall of the arc-shaped structure of the locking member 53 can rotate into the arc-shaped locking groove 215 along the inner wall of the arc-shaped locking groove 215, thereby locking the glue outlet seat 21; conversely, when the lever 51 drives the locking member 53 to rotate to the second position, the outer wall of the arc-shaped structure of the locking member 53 can rotate out of the arc-shaped locking groove 215 along the inner wall of the arc-shaped locking groove 215, thereby unlocking the glue outlet seat 21, so as to dismount the glue outlet seat 21 from the valve shell 31.
