Description

A kind of puncher

Affiliated technical field

The utility model relates to a kind of puncher.

Background technology

A kind of device that is used on as the paper analog, charging and attacking out a through hole specially of puncher, its operation principle of the puncher of existing similar type is: the certain thickness paper analog that at first will need to punch is put well and is located with slide rule by corresponding position, firmly depress plastics again and press hand, the circular knife sector-meeting that be installed on the movable block this moment goes out a through hole in the paper analog blanking that following of the indirect effect of this power places, circular shear blade continue move downward under the effect of user's pressure run into base platform after, the user unclamps depression bar, this moment, depression bar can be raised to the home position under the effect of its afterbody one spring, in order to carrying out next punching action.The puncher of the type comparatively speaking, its weak point is: the paper analog that the punching heels can not be discharged easily, circular shear blade damages easily, is perforated in the process of using can not be located exactly, makes troubles to the user.

The utility model content

The purpose of this utility model provides that a kind of punching heels can be discharged easily, the circular shear blade puncher that paper analog not fragile, that be perforated can be located exactly in the process of using.

A kind of puncher that the utility model provides, comprise base, support, depression bar, plastics are pressed hand, spring, circular shear blade and slide rule, described plastics press gloves to be connected on the depression bar, the top of depression bar and support forms hinged by a locating shaft, spring is assemblied on this locating shaft, base sheath is connected on the bottom of support, the middle part of base is provided with position, a hole, slide rule is placed on this position, hole, be provided with a movable block between described depression bar and the support, the upper end of movable block and depression bar flexibly connect by a locating shaft, the lower end of movable block connects circular shear blade by a stay, and described stay is L-shaped, and the lower end of stay has a through hole, circular shear blade is enclosed within on the stay after passing this through hole, and the upper end of stay is fixed on the movable block by screw; The middle part of described movable block has a space roughly triangular in shape, and the bottom of this triangle space is provided with a through hole, and this through hole is communicated with the inside position of circular shear blade, and a side of triangle space is communicated with the middle part of support.

Base described in the utility model and support are being respectively equipped with a big shrinkage pool and a small through hole with the circular shear blade corresponding position, are placed with a plastic mattress in the big shrinkage pool, and the bottom surface of described plastic mattress is provided with a small convex pillar, and small convex pillar is placed in the small through hole.

Be provided with an elasticity spacer between the position, hole of slide rule described in the utility model and placement slide rule, the place is provided with a projection in the middle of the elasticity spacer, and the back side of slide rule is provided with and the corresponding groove of himself scale.

When the utility model uses, the certain thickness paper analog that at first will need to punch is put well and is accurately located with slide rule by corresponding position, firmly depress plastics again and press hand, be installed in the paper analog blanking that the circular knife sector-meeting on the movable block puts well following of the indirect effect of this power this moment and go out a through hole, circular shear blade continue move downward under the effect of user's pressure run into plastic mattress after, the user unclamps depression bar, this moment, depression bar can be raised to the home position under the effect of its tail springs, in order to carrying out next punching action.In this process, because the special construction of circular shear blade, defective material after the punching can be stayed its inside position, and along with next time punching action, the defective material of its inside position can be squeezed out circular shear blade and be scattered out with being communicated with of mid-stent from the triangle space of movable block.In this process, the plastic mattress that is placed on the base plays a part the protection circular shear blade; The slide rule back side has and the corresponding groove of himself scale, and is projection on the spacer, because spacer is flexible, so when the user spurs slide rule, can form an effective positioner with spacer.

In sum, the utlity model has the punching heels discharge convenient, effectively protect circular shear blade, characteristics such as the paper analog accurate positioning that is perforated, operation facility.

The utility model will be further described below in conjunction with accompanying drawing.
