In addition to rotating the connecting rod 2 to adjust the distance between the adhesive tape roll 4 and the corrugated cardboard, the worker can also slide the inner rod 22 to adjust the distance between the adhesive tape roll 4 and the corrugated cardboard, which provides a way for the worker to adjust the distance between the adhesive tape roll 4 and the corrugated cardboard, so that the adjustment of the distance between the adhesive tape roll 4 and the corrugated cardboard is more flexible and convenient.
Referring to fig. 3, an installation groove 12 with a rectangular cross section is formed in one of the inner side walls of the outer rod 21, a plurality of rectangular clamping grooves 13 are formed in one side wall of the inner rod 22 close to the installation groove 12, the plurality of clamping grooves 13 are arranged at equal intervals along the length direction of the inner rod 22, the notch of each clamping groove 13 is flared, and when the inner rod 22 slides relative to the outer rod 21, the plurality of clamping grooves 13 are aligned to the installation groove 12 one by one. A clamping block 14 is embedded in the mounting groove 12 in a sliding manner, a spring 15 is fixedly connected between the clamping block 14 and the bottom of the mounting groove 12, when the spring 15 is in a natural state, the clamping block 14 is inserted into the corresponding clamping groove 13, and when the spring 15 is in a compressed state, the clamping block 14 is contracted in the mounting groove 12 and separated from the corresponding clamping groove 13. The outer rod 21 is also embedded with a pull rope 16, one end of the pull rope 16 extends into the mounting groove 12 and is fixedly connected with the clamping block 14, and the other end of the pull rope 16 extends out of the side wall of the outer rod 21 and is fixedly connected with a pull ring 17. The outer side wall of the outer rod 21 is also fixedly connected with a draw hook 18, and the draw hook 18 is used for hooking the draw ring 17 when the fixture block 14 is separated from the clamping groove 13, so that the fixture block 14 is prevented from being accidentally inserted into the clamping groove 13 under the resilience force of the spring 15. The mounting groove 12, the locking groove 13, the latch 14, the spring 15 and the pull rope 16 form a second locking mechanism for locking the position of the inner rod 22. After the inner rod 22 slides to a proper position, the worker slightly slides the inner rod 22 to make the nearest card slot 13 face the mounting groove 12, and after the mounting groove 12 is aligned with the corresponding card slot 13, the card block 14 is automatically inserted into the card slot 13 under the resilience of the spring 15, the relative position between the inner rod 22 and the outer rod 21 is locked, the length of the connecting rod 2 is locked, and the adhesive tape roll 4 (as shown in fig. 1) and the corrugated board can maintain a proper distance. If the inner rod 22 is to be slid again, the worker pulls the fixture block 14 through the pull rope 16, the fixture block 14 compresses the spring 15 and retracts into the mounting groove 12, after the fixture block 14 is separated from the fixture groove 13, the position of the inner rod 22 is not restrained by the fixture block 14, and the inner rod 22 can slide relative to the outer rod 21 again.
The implementation principle of the embodiment is as follows: when the distance between the adhesive tape roll 4 and the corrugated board is large, a worker can rotate the connecting rod 2 upwards around the rotating shaft 6, the supporting rod 3, the adhesive tape roll 4 and the nut 5 are synchronously screwed up along with the connecting rod 2 and are close to the corrugated board, the distance between the adhesive tape roll 4 and the corrugated board is reduced, and the adhesive tape on the adhesive tape roll 4 can be more stably and accurately pasted on the corrugated board. In the process that a worker rotates the connecting rod 2 upwards, the ratchet wheel 7 rotates synchronously along with the rotating shaft 6, the pawl 8 continuously slides over the tooth backs of the ratchet wheel 7 under the action of the torsion spring 9, when the distance between the adhesive tape roll 4 and the corrugated board is adjusted and integrated timely, the worker loosens the connecting rod 2, the pawl 8 can be automatically inserted into the tooth grooves corresponding to the ratchet wheel 7 under the resilience force of the torsion spring 9, and further the ratchet wheel 7, the rotating shaft 6, the connecting rod 2, the supporting rod 3, the adhesive tape roll 4 and the nut 5 are locked, and the adhesive tape roll 4 and the corrugated board can maintain a proper distance. When it is necessary to rotate the link 2 downward to increase the distance between the tape roll 4 and the corrugated cardboard, the worker rotates the pawl 8 by the handle 10 and disengages the pawl 8 from the ratchet 7. In addition, the worker can adjust the distance between the tape roll 4 and the corrugated cardboard by sliding the position of the inner lever 22.
