A hot runner 2 is opened on the hanging platform 1, and a fixing plate 5 is provided on the nozzle body 3. The fixing plate 5 is fixedly connected to the nozzle body 3. A connecting pipe 6 is provided on the fixing plate 5. The connecting pipe 6 is fixedly connected to the fixing plate 5. The connecting pipe 6 is inserted into the hot runner 2. A mounting block 9 is fixedly connected to the hanging platform 1, and the mounting block 9 is inserted into the groove of the fixing plate 5. A handle 10 is provided on the outside of the fixing plate 5. The handle 10 passes through the fixing plate 5, and the handle 10 is slidably connected to the fixing plate 5. The other end of the handle 10 is fixedly connected to a slider 11. This arrangement facilitates the movement of the slider 11. The slider 11 is slidably connected to the fixing plate 5. A positioning block 12 is fixedly connected to the outside of the slider 11, and a limiting spring 13 is attached to the outside of the handle 10 between the slider 11 and the fixing plate 5.

[0027] In one embodiment, please refer to the attached specification Figure 1 and 2 As a further solution of the utility model, a nozzle head 4 is provided at the bottom of the nozzle body 3, and the nozzle head 4 is fixedly connected to the nozzle body 3. This arrangement can inject the solution.

[0028] In one embodiment, please refer to the attached specification Figure 2 and 4 As a further solution of the utility model, a sealing gasket 7 is provided on the fixing plate 5, and the sealing gasket 7 is fixedly connected to the fixing plate 5. The sealing gasket 7 is on the outside of the connecting tube 6, and the sealing gasket 7 is slidably connected to the connecting tube 6. The sealing gasket 7 is made of rubber material, and a supporting spring 8 is provided on the inside of the sealing gasket 7, and the supporting spring 8 is fixedly connected to the sealing gasket 7.
