The driving screw rod 41 is parallel to the wall surface. In order to improve the stability of the sliding guide of the mounting support 2, the guide sliding block 45 at the bottom of the mounting support 2 is a T-shaped sliding block, and the guide sliding rail 44 on the top surface of the mounting basket 1 is a T-shaped sliding rail.

[0038] With reference to Figure 4 and Figure 5 The tearing assembly 3 comprises a winding roller 31 axially rotatably mounted on the mounting support 2 and used for winding the separation joint adhesive tape 7, and a winding motor 32 mounted on the top of the mounting support 2 and used for driving the winding roller 31 to rotate. The output shaft of the winding motor 32 is arranged downwardly. The winding roller 31 has a fixing structure for fixing the separation joint adhesive tape 7. The fixing structure comprises a fixing groove 311 opened in the radial direction of the winding roller 31 and a fixing block 312 matched with the fixing groove 311 and used for fixing the separation joint adhesive tape 7 in the fixing groove 311. In order to realize the stable arrangement of the fixing block 312 in the fixing groove 311, the fixing block 312 and the winding roller 31 are locked by a locking structure. The locking structure comprises an elastic clamping piece 313 elastically connected to the outer side surface of the fixing block 312 and a locking groove 315 opened on the winding roller 31 at the fixing groove 311 and used for matching with the elastic clamping piece 313.

[0040] With reference to Figure 5 In order to facilitate the extraction of the fixing block 312 from the fixing slot 311, the bottom of the fixing slot 311 is provided with an elastic seat 34 used for abuttingly matching with the fixing block 312. The existence of the elastic seat 34 drives the fixing block 312 to always have a tendency to be pulled out of the fixing slot 311. When the unlocking piece 331 drives the elastic clamping piece 313 to be compressed in the direction of the fixing block 312, the clamping portion 3131 of the elastic clamping piece 313 is separated from the locking slot 315. Then, the fixing block 312 is quickly pulled out of the fixing slot 311 through the action of the elastic seat 34, which is helpful for taking the fixing block 312.
