Abstract

The utility model relates to a hand mechanical puncher of a rubber stopper of a sawtooth opening, which mainly comprises a slide rail (1), a base (2), a rubber stopper fixed clamp (3), a slidable clamp (4), a main beam (5), a positioning pin (10) and a cylindrical cutter (11), and is characterized in that: one slidable clamp (4) is sleeved at the upper end of the slide rail (1), a screw rod at the right end of the slidable clamp (4) is connected with a nut at the middle part of the main beam (5) through a bolt, a stress handle is fixed at the top end of the main beam (5), an upper worm is connected onto the middle part of the main beam (5), the tooth surface of the upper worm is meshed with that of an upper end of a worm gear in a line contact mode, a lower worm is welded at the middle lower part of the main beam (5), the tooth surface of the lower worm is meshed with that of the lower end of the worm gear in the line contact mode, the positioning pin (10) is arranged at the lower end of the main beam (5), and the cylindrical cutter (11) is sleeved on the main beam (5). In the hand mechanical puncher of the rubber stopper of the sawtooth opening, the cylindrical cutter (11) at the sawtooth opening is rotated by rotating a handle of the worm gear, the sharp knife edge is quickly rotated downwards under the pressure of the stress handle, and the labor and time are saved compared with the traditional puncher.

Description

The hand mechanical card punch of sawtooth mouth rubber stopper

Technical field

The utility model relates to the hand mechanical card punch of sawtooth mouth rubber stopper of a kind of chemical laboratory and research office's use.

Background technology

The rubber stopper card punch is the most frequently used a kind of experimental tool in chemical experiment teaching and scientific experiment chamber, existing rubber stopper card punch generally all is to be with a handle by the upper end, cylindrical tube cutter of middle welding, directly grip the handle of upper end during use, rotation is to the method punching that presses down, and this method operation is not only reined in hand but also required great effort.

Summary of the invention

Operate the problem of reining in the hand effort in the above-mentioned existing experimental provision in order to overcome, the utility model intends providing a kind of time saving and energy saving hand mechanical card punch of sawtooth mouth rubber stopper of operating.

The technical scheme that its technical problem that solves the utility model adopts is: the hand mechanical card punch of sawtooth mouth rubber stopper is by slide rail, base, the rubber stopper geometrical clamp, slip clamp, girder, force application handle, last worm screw, worm gear, following worm screw, alignment pin, the tubular cutter is formed, it is characterized in that: slide rail is fixed on the base by slide rail lowermost end screw, the slide rail lower end connects a rubber stopper geometrical clamp by cranse, slip clamp of slide rail upper end socket, the screw rod of slip clamp right-hand member is connected by the bolt form with the nut at girder middle part, a force application handle is fixed on the girder top, the girder middle and upper part connects one and goes up worm screw, the last worm tooth-surface and the worm gear upper end flank of tooth mesh with the line contact form, following worm screw of girder middle and lower part welding, the flank of tooth of following worm tooth-surface and worm gear lower end meshes with the line contact form, there is an alignment pin girder lower end, and the tubular broach shell is connected on the girder.

Advantage of the present utility model is: drive the rotation of sawtooth mouth tubular cutter by rotating the worm gear rocking handle, under force application handle pressure, the quick backspin of the sharp edge of a knife saves time than traditional card punch is laborsaving.

The beneficial effects of the utility model are: for laboratory and research office provide a kind of operation comfortable, laborsaving, novel rubber stopper drilling tool easily punches.
