When doing chemical experiment, connect the conduit of different-diameter through conventional rubber closure, owing to connecting the pipe diameter size of instrument, so the rubber closure being accomplished by different model gets, with rubber closure, the hole that aperture is different.When some containers need to be tightly connected by conduit with other containers, rubber closure can solve this problem well.Traditional card punch, needs to punch with external force extruding, and this method the most easily trains off hole, and wastes time and energy, inefficiency.
Utility model content
The defect existed for prior art, this utility model provides a kind of drill bit and rubber closure that can conveniently clamp different-diameter, and when rubber closure is punched by manual rotation operation block and handle rotates, opponent does not has the manual rubber closure card punch of frictional force.
For solving above-mentioned technical problem, the technical scheme that this utility model is used is as follows: manual rubber closure card punch, including base, chuck and the operation block in cylindrical structural, the upper surface middle part of base offers perpendicular screwed hole, the upper surface left side edge of base is fixedly connected with the montant set up, the top of montant level to the right is fixedly connected with cross bar, and the right part of cross bar is fixedly connected with vertically disposed sleeve pipe, and the inwall of sleeve pipe is provided with female thread；The upper surface sidepiece of operation block is fixedly connected with handle, on handle, turning set is provided with sliding sleeve, the cylindrical outer surface of operation block is provided with external screw thread, the bottom surface of operation block is fixedly connected with fixing seat, fixing center, seat bottom face upwards offers installing hole, in the middle part of fixing seat, level offers the horizontal screwed hole being connected with installing hole, and horizontal screwed hole female thread connects has holding screw, installing hole to be fixedly connected with drill bit by holding screw；Operation block is connected with casing threads；
Chuck is cylinder, the lower surface center of chuck is to having screw rod, the upper surface edge of chuck is upwards provided with a circle riser, the inwall of riser circumferentially direction is uniformly fixedly connected with three compression springs, three compression springs are all disposed radially, the other end of three compression springs has been fixedly connected with fixture block, and chuck is threadeded with perpendicular screwed hole by screw rod；The vertical axis of sleeve pipe, operation block and chuck is in same straight line.
It is equipped with rubber cover on the clamping face of fixture block.
This utility model has the advantages that
1, operation block is connected with casing threads, makes operation block move up and down in sleeve pipe by handle positive and negative rotation work block, it is achieved the rotary cutting of drill bit；
2, installing hole can be installed the drill bit of different-diameter and is fixed on fixing seat by the drill bit of different-diameter by holding screw；
3, chuck and base have employed screw rod and the connected mode of perpendicular screwed hole threaded connection detachable, are convenient for changing the chuck of damage；
4, the fixture block in chuck is fixed by compression spring, can fix different-diameter rubber closure；
5, the clamping face of fixture block is provided with rubber cover, rubber closure can be protected without damage when clamping rubber closure;
6, on handle, turning set is provided with sliding sleeve, make staff when turning handle, it is to avoid the frictional force between hands and handle, makes handle more convenient to use.
In sum, this utility model is reasonable in design, simple in construction, and hand rotation operation block provides the cutting force of drill bit, fixing seat and chuck can fix drill bit and the rubber closure of different-diameter respectively.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, manual rubber closure card punch, including base 1, chuck 2 and the operation block in cylindrical structural 3, the upper surface middle part of base 1 offers perpendicular screwed hole 4, the upper surface left side edge of base 1 is fixedly connected with the montant 5 set up, the top of montant 5 level to the right is fixedly connected with cross bar 6, and the right part of cross bar 6 is fixedly connected with vertically disposed sleeve pipe 7, and the inwall of sleeve pipe 7 is provided with female thread；The upper surface sidepiece of operation block 3 is fixedly connected with handle 8, on handle 8, pivoted housing is provided with sliding sleeve 9, the cylindrical outer surface of operation block 3 is provided with external screw thread, the bottom surface of operation block 3 is fixedly connected with fixing seat 10, fixing seat 10 bottom center position upwards offers installing hole 11, in the middle part of fixing seat 10, level offers the horizontal screwed hole 12 being connected with installing hole 11, and horizontal screwed hole 12 female thread connects holding screw 13, and installing hole 11 is fixedly connected with drill bit 14 by holding screw 13；Operation block 3 is threadeded with sleeve pipe 7.
Chuck 2 is in cylinder, the lower surface center of chuck 2 is to having screw rod 15, the upper surface edge of chuck 2 is upwards provided with riser 16, the inwall of riser 16 circumferentially direction is uniformly fixedly connected with three compression springs 17, three compression springs 17 are all disposed radially, the other end of three compression springs 17 has been fixedly connected with fixture block 18, and chuck 2 is threadeded with perpendicular screwed hole 4 by screw rod 15；The vertical axis of sleeve pipe 7, operation block 3 and chuck 2 is in same straight line.
Rubber cover 19 it is equipped with on the clamping face of fixture block 18.
nullWork process of the present utility model is as follows: during use，The rubber closure needing punching is clamped between the fixture block of chuck 2，Diameter according to rubber closure desired aperture chooses the drill bit 14 of correspondence，The drill bit 14 chosen is fixed in the installing hole 11 of fixing seat 10 by holding screw 13，Manually rotate clockwise the handle 8 in operation block 3，Operation block 3 rotates down at sleeve pipe 7 internal coiling，When drill bit 14 contacts with chuck 2 downwards，The center of rubber closure is cut out required aperture by drill bit 14 rotary cutting，The most manually rotate counterclockwise the handle 8 in operation block 3，Make block to be rotated up at sleeve pipe 7 internal coiling，Drill bit 14 separates with rubber closure，The perforated surfaces of rubber closure is inverted and is fixed in chuck 2，The most manually rotate clockwise the handle 8 in operation block 3，Override interrupt action，Beaten hole inner wall smooth can be ensured.
During the aperture needed when needing to get reducing on rubber closure, use the drill bit 14 of required different-diameter to punch in two perforated surfaces of rubber closure respectively, the rubber closure needed for reducing can be processed.
Shape of the present utility model, material, structure etc. are not made any pro forma restriction by the present embodiment; every any simple modification, equivalent variations and modification made above example according to technical spirit of the present utility model, belongs to the protection domain of technical solutions of the utility model.
