Description

Adhesive tape cutter

Technical field

The utility model relates to the stationery class in a kind of office appliance, is used for the cutter of adhesive tape cutting specifically.

Background technology

Adhesive tape is the indispensable consumable store a kind of commonly used of office, and of many uses, consumption is very big, when the user when using adhesive tape sticking, its cut-out mode is usually by means of other instruments, for example scissors or sharp blade, very trouble is used in Continuous pressing device for stereo-pattern serviceable tool cut-out on one side on one side.At present existing a kind of easy adhesive tape cutter, but do not have safety prevention measure, the user is careless slightly, and sharp blade will hurt finger.China Patent No. is 02117124.6 " a kind of adhesive tape cutter of band blade safety device ", by safety device is set in blade portion to avoid the incised wound finger, this safety device adopts the blade activity and safety device is fixed or blade is fixed and the technical measures of safety device activity, its complex structure, be applied to joint sealing or packing mostly, limitation is arranged in the use, paste file and so on work for the office space, above-mentioned patent is also inapplicable.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of simple in structure, the easy to use and adhesive tape cutter that is perfectly safe.

Technical matters of the present utility model is achieved through the following technical solutions:

A kind of adhesive tape cutter, comprise the cutter mount that belt pulley is installed, cutter mount is provided with cutting blade and safety device, it is characterized in that described safety device promptly is provided with the movable cover cap of the movable telescopic that is higher than the blade edge of a knife at the adjacent knife blades place, be provided with the spring that its activity is resetted in the movable cover cap, this spring housing is contained on the spring perch of fixing with cutter mount.

The described blade edge of a knife is shape or serration linearly.

Described blade is connected or screw retention with adhesion agent with cutter mount.

Described adhesive tape cutter seat bottom surface is provided with antiskid glue cushion.

Compared with prior art; the blade safety device that the utility model adopts; comprise movable flexible movable cover cap; and being arranged on blade on the adhesive tape cutter seat, movable guard caping end is higher than the blade edge of a knife, contracts in the movable cover cap during cutting and exposes the edge of a knife; the movable cover cap protection that the edge of a knife was reset after cutting was finished; it is simple in structure, is convenient to implement, and uses fool proof.

The specific embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As Fig. 1～shown in Figure 4, the utility model adhesive tape cutter, it comprises adhesive tape cutter seat 1, the cutter mount inner hollow, cement injection is to increase pedestal weight, shrouding 9 sealings of bottom open end to match, and be provided with antiskid glue cushion in the shrouding bottom surface, cutter mount is provided with can be for the belt pulley 2 of adhesive tape installation, this belt pulley has three kinds of support patterns: a kind of is that the wheel shaft 10 that supports belt pulley extends two short pins to both sides, and short pin is embedded in associated cutter mount " " type groove, and this groove is by perpendicular grooves, inclined groove, the corner groove is formed, short pin is entered by perpendicular grooves, mode of operation must enter inclined groove, and the corner groove is longer, uses during for the packing collection, short pin slips into the corner groove during i.e. packing collection, makes belt pulley not exceed the cutter mount end face; The wheel shaft of another kind of supporting belt pulley is cylindric, one chute arranged at its bottom, this chute be installed in the slippage that matches of sliding pin on the cutter mount, belt pulley is axially extrapolated with belt pulley before installing, put behind the belt pulley and advance, what do not influence belt pulley freely rotates (not shown); Also having a kind of is opening door, can shake out the door of unlatching in cutter mount one side setting, the door inboard is provided with siamesed adhesive tape wheel shaft, after belt pulley puts the adhesive tape wheel shaft, at closing time by the translot of door one side be located at cutter mount on the cooperating of the removable pin that can pass, it is fixing to realize locking a door.(not shown)

Cutting blade 6 is installed in the cutter groove that cutter mount 1 processes in advance, connects or screw retention by adhesion agent, and its blade edge of a knife 5 is designed to the sharp linear or the serration edge of a knife, in order to cutting.6 places are provided with safety device in adjacent knife blades, this safety device is meant that being provided with one at cutter mount 1 adjacent knife blades place can supply the passage 7 of movable cover cap 3 upper and lower slips, passage and movable cover cap both sides are designed to up-narrow and down-wide, prevent that movable cover cap 3 from skidding off from passage 7 tops, movable cover cap is filled in by the bottom during installation.The top of movable cover cap 3 is higher than blade edge of a knife 1-2mm, and the edge of a knife 5 is not exposed, and effectively protects user's safety; be equipped with in the movable cover cap 3 and make its spring that resets 4; spring housing is contained on the spring perch 8, and this spring perch on the omoplate of cutter mount 1 inwall, and is sealed passage 7 bottoms with screw retention.

When adhesive tape cutter uses, pull out adhesive tape to appropriate length from belt pulley 2, press down adhesive tape then, at this moment, the top of adhesive tape compressing activity cover cap 3 is along with continuing firmly, blade cut off adhesive tape when movable cover cap slipped into passage 7, after adhesive tape cut off, movable cover cap resetted under the effect of spring force fast, can cut next time.
