As shown in fig. 6, the lower end of the middle connecting rod 502 is provided with an obliquely arranged glue pressing roller 53, and the rotation axis of the glue pressing roller 53 is perpendicular to the glue discharging direction of the glue gun 51. In the process that the connecting part 50 drives the glue gun 51 to move up and down, because the length of the lower connecting rod 503 is greater than that of the upper connecting rod 501, the upper connecting rod 503 and the lower connecting rod 503 together with the middle connecting rod 502 can incline in the vertical direction relatively in the downward swinging process, and the glue gun 51 and the glue pressing roller 53 are driven to incline, so that the glue outlet 51a of the glue gun 51 and the glue pressing roller 53 are basically positioned in the same vertical direction in the up-and-down movement. If the length of the upper link 501 is the same as that of the lower link 503, the glue outlet 51a of the glue gun 51 and the glue pressing roller 53 inevitably generate horizontal displacement when moving up and down.

In addition, the clamping jaw 10 is further provided with a rubber pad 10b on the surface contacting with the inner flange 11, so that the friction force between the clamping jaw and the inner flange 11 is improved, slipping during clamping and fixing is avoided, and the inner wall of the inner flange 11 is protected.

In the actual construction process, the clamping ring 3 needs to be unscrewed, as shown in fig. 8, the clamping ring 3 rotates and moves upwards, the clamping jaws 10 move inwards under the action of the clamping jaw springs 12, and the clamping jaws 10 are retracted so as to sleeve the inner layer flange 11 outside the clamping jaws 10. And then the clamping ring 3 is screwed, as shown in fig. 7, the clamping ring 3 rotates and moves downwards, the clamping jaws 10 are pushed to move outwards to clamp and fix the inner layer flange 11, the positioning seat 4 and the rod body 1 are in a coaxial positioning state, and the outer shell 2 and the outer layer flange 6 are fixed. The rod body 1 moves downwards, as shown in fig. 9, the positioning seat 4 drives the inner layer flange 11 to move along the radial direction of the inner layer pipe 7 of the double-layer pipe fitting, so that the inner layer flange 11 and the inner layer pipe 7 are kept in a positioning state. In order to facilitate the hot melt adhesive to smoothly enter between the connecting surfaces of the inner layer flange 11 and the inner layer pipe 7, a certain gap of about 1 to 3mm can be reserved between the inner layer flange 11 and the inner layer pipe 7 according to the thickness of the pipe wall. The outside of the rod body 1 can be connected with power units such as a hydraulic motor and the like, and can also be rotated manually, but the manual rotation needs an operator to master skilled skills, otherwise, molten glue is easy to accumulate at certain positions due to unstable rotating speed, and in order to ensure uniform gluing, the rod body 1 is preferably driven to rotate at a constant speed by the power units such as the hydraulic motor and the like.
