Abstract
The utility model belongs to laboratory instruments and particularly relates to a rubber plug hole puncher used in a laboratory. The hole puncher comprises an inner rod (1) and a sleeve (2). The outer wall of the inner rod (1) and the inner wall of the sleeve (2) are movably connected through threads. A centering drill (4) is arranged at the bottom of the inner rod (1). A holding rod (5) is arranged at the top of the inner rod (1). An annular tool bit (6) is arranged at the bottom of the sleeve (2). A push rod (7) is fixed on the sleeve (2). The rubber plug hole puncher has the advantages of being simple in structure and practical in function. At utilization time, first, the centering drill is used for fixing the hole puncher on a rubber plug, the push rod is pushed to enable the annular tool bit at the bottom of the sleeve to rotate downward, after the rubber plug is punched, the push rod is pushed in an opposite direction to enable the sleeve to move upward, so that a rubber plug core left on the centering drill is exposed. Consequently, the work can be finished after the rubber plug core is removed and is thrown away. The rubber plug hole puncher is convenient, saves labor and greatly improves hole punching efficiency.
Description
Technical field
The utility model belongs to the experiment utensil, particularly a kind of laboratory rubber stopper card punch.
Background technology
Card punch is the laboratory common tool, be mainly used in the rubber stopper central punch, traditional card punch is a hollow metal bar, one end is a circular open, and other end both sides stretch out as handle, during use, two hands are respectively caught two holding rods of an end, the rotation card punch advances to rubber stopper is inner, finishes punch operation.The tradition card punch uses comparatively hard, and after punching was finished, the plug core of staying card punch inside was difficult to again remove.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of laboratory rubber stopper card punch is provided, and this card punch is not only laborsaving, also the convenient plug core of removing.
To achieve these goals, the technical solution of the utility model is as follows: a kind of laboratory rubber stopper card punch, bar and sleeve in comprising, the outer wall of interior bar and the inwall of sleeve flexibly connect by screw thread, the bottom of interior bar is provided with pilot bit, the top of interior bar is provided with holding rod, and the bottom of sleeve is provided with annular cutter head, and push rod is fixedly arranged on the sleeve.
The utlity model has advantage simple in structure, that function is practical.During use, with pilot bit card punch is fixed on the rubber stopper earlier, promoting push rod makes the annular cutter head rotation of cover tube bottom downward, get through behind the rubber stopper push rod pushed away to make to opposite direction and expose the plug core of staying on the pilot bit after moving on the sleeve, take off to throw away and get final product, convenient and labor-saving, improved perforating efficiency greatly.
