Description

(4) The present invention relates to a tape cutting device for a tape holder.

A conventional tape holder has a tape base and a tape cutting device above its grip, the tape is installed on the tape base, and the tape cutting device has a knife, which is fixed on the knife base. Both are installed so that they cannot be moved, and the knife is designed to cut the tape by holding the grip with one hand and moving the entire tape holder, so that the knife cannot be cut directly by moving the knife.

In order to remedy the above-mentioned drawback of the conventional tape holder in which the knife is fixed and cannot be moved, an object of the present invention is to move the knife only without moving the entire tape holder by moving the knife and moving the tape. An object of the present invention is to provide a tape cutting device for a tape holder that can be cut.

In order to achieve the above object, the tape holder tape cutting device described in the claims of the present invention is provided with a pull plate at the front end of the lower grip portion of the tape holder. This pulling plate forms a shaft connecting portion in the middle portion, and is fitted into the shaft connecting portion with one shaft fixed laterally to the inner plate to connect the pulling plate to the inner plate by a shaft. Further, a recessed groove is provided in the middle portion of the shaft connecting portion, and the support metal is penetrated through the shaft to be pivotally connected. The upper end of the backing presses the tape against the outer surface of the roller. In addition, the back metal is provided with a torsion spring on the rear side surface to give the metal a certain elasticity. The upper part of the pull plate forms a male piece to contact the rear vertical wall of the slide. The slide is L-shaped, with a knife below it, and a knife table below the knife so that it can move together a set distance back and forth. Both the slide and the knife are provided with two slots, and are attached to the knife base with two screws. Then, the trigger plate is provided with the push rod extended downward, and when the trigger is pressed, the trigger plate pivots a little about the axis, so that the upper end of the trigger plate faces the vertical wall of the slide bar in front. The slide then pushes the knife forward at the same time, protruding slightly from the knife base and cutting the tape. Also, if you release your finger pushing the trigger, the trigger plate will be returned to its original position due to the elasticity of the spring, and the slide will no longer be put on the tip of the trigger plate. Return the knife to its original position so that it does not stick out.

(Action)
The tape cutting device of the present invention cuts the tape by pushing the trigger of the trigger plate only when cutting the tape and cuts the tape a little, and when the trigger is released from the finger, the knife is automatically returned to the original position by the elasticity of the spring. Will be returned.

The outer plate 20 has two laterally oriented pivots 21 on its inner surface, and the ends of the two pivots 21 are just opposite the two screw holes 15 of the inner plate 11, and the inner plate is screwed with two screws 40. 11 is screwed. One of the two pivots 21 on the front side of the outer plate 20 is fitted on one roller 22, and the roller 22 can be rotated by the pivot 21. Further, a horizontal knife stand 23 is fixedly mounted on the inner surface above the front side of the outer plate 20, and the knife stand 23 has a fitting projection 231 formed on the fitting hole 16 of the inner plate 11 and fixed on the front side thereof. I do. Further, two fixed rings 232 each having one screw hole 233 are integrally provided on the upper surface thereof, and a receiving groove 234 is provided at the center thereof. Then, the knife 24 is placed on the upper surface of the knife stand 23. The knife 24 has two slots 241 that fit into the two fixed rings 232 of the knife base 23 so that the knife 24 can be moved slightly back and forth on the knife base 23. The knife 24 further has two localization holes 242. An L-shaped slide 25 is placed on the knife 24, and the slide 25 has two slots 251 to be fitted into two fixed rings 232, and further has two downwardly fitting projections on its lower surface. 252, which fits into the positioning hole 242 of the knife 24 so that the slide 25 can move the knife 24 together.

Next, the rear side of the slide metal 25 forms a vertical downward pushing wall 253. The pushing wall 253 has a lateral projection 254 on the inner surface thereof, and the projection 254 fits into one end of the spring 255. The other end of the spring 255 is fixed in the receiving groove 234 of the knife table 23. A slightly L-shaped plate 26 is further installed on the upper surface of the slide metal 25, and the L-shaped plate 26 forms a horizontal plate portion 261 at a lower portion thereof, and the horizontal plate portion 261 has two circular holes 262, After the two screws 41 pass through the two circular holes 262, they pass through the two slots 251 of the slide metal 25 and the two slots 241 of the knife 24, and are firmly screwed into the screw holes 233 of the two fixed rings 232 of the knife base 23. The L-shaped plate 26 is fixedly mounted on the knife base 23, so that the slide metal 25 and the knife 24 are sandwiched between them.

Next, as shown in FIGS. 2 and 3, the grip portion 13 is provided with a pulling plate 30 in front of the gripping portion 30, and the pulling plate 30 has a shaft connecting portion 31 at a central portion thereof. Is inserted into the central shaft hole, and is screwed into the outer end of the shaft 18 with the screw 42, so that the shaft 18 is connected to the shaft connecting portion 31. Further, the shaft connecting portion 31 forms a recessed groove 311 in the middle stage thereof, pivotally connects the plate 32 in the recessed groove 311, and assembles the torsion spring 33 on the rear side of the plate 32, The elasticity is provided to the backing plate 32. The front end of the backing plate 32 presses the tape against the outer surface of the roller 22. Further, the pulling plate 30 is provided with a bar 34 at its upper end to come into contact with the pushing wall 253 of the slide 25, to slide the slide 25 forward and to move the knife 24 at the same time. The tape can be cut. The pulling plate 30 is further provided with a lateral position limiting protrusion 35 on the left side surface, and the position limiting protrusion 35 fits with the position limiting groove 17 of the inner plate 11. Further, the pulling plate 30 forms a push rod 36 extending downward, and a lateral projection 361 aligned with the circular rod 121 of the seat base 12 is provided on the rear surface of the push rod 36, and is inserted into one end of the spring 37.

Next, the combination and operation of each part according to the present embodiment will be described. First, as shown in FIGS. 4 and 5, when the shaft connecting portion 31 of the pulling plate 30 is connected to the shaft 18, when the user presses the pusher 36, the pulling plate 30 turns around the shaft 18 and the upper end thereof. The towel 34 moves forward and pushes the slide 25 forward. Then the knife 24 moves forward and cuts the tape. The position limiting groove 17 of the inner plate 11 limits the moving distance of the position limiting protrusion 35 of the pulling plate 30, so that the advance distance of the slide metal 25 is also limited to the sliding groove 235, the slot 241, and the slot 251, so that the tape can be accurately measured. It is possible to perform safe cutting work.

(5) As shown in FIG. 5, when the tape of the knife 24 completes the cutting operation, the pressing plate 36 is released and the pulling plate 30 is returned to the original position by the recovery of the elasticity of the spring 37. Therefore, the slide 25 is released from the pressing of the male piece 34, and is returned to the original position by the resilience of the spring 255, so that the knife 24 is pulled back into the knife base 23. This prevents injuries to the user's fingers and ensures the safety of operation of the tape holder.

The recessed groove 311 of the pulling plate 30 according to the embodiment of the present invention has the backing plate 32 installed therein, and the backing plate 32 elastically presses the tape against the surface of the roller 22 by the action of the torsion spring 33. Therefore, it is possible to prevent the tape from reversing or falling.

The present invention does not need to move the entire holder when cutting the tape like a conventional tape holder, it is convenient to cut the tape just by pressing the pusher, and the knife protrudes from the tape base only when cutting the tape Safe to use.
