Abstract

A cap tightener comprises a threaded base, a clamping rod and a lead screw, wherein an inner threaded hole is formed in the middle part of the threaded base; the lead screw is movably mounted in the inner threaded hole by means of screw threads; a tie rod is articulated to the middle part of the clamping rod; a shaft sleeve rotating around the lead screw is mounted in a limiting way on the bottom of the lead screw; and the tie rod is articulated to the shaft sleeve. The cap tightener is simple in structure and covers the shortcoming of insufficient hand strength of people in a conventional method; and the cap tightener is capable of clamping a bottle cap, thereby saving the time of opening the cap, and is convenient for use.

Description

A kind of cap screwing device

Technical field

The utility model relates to a kind of life appliance, is specifically related to a kind of cap screwing device.

Background technology

In the daily life, people often need open the for example bottle cap of beverage, liquor and so on, and this bottle cap generally is screwed in bottle mouth position; When people need open, generally oppositely turn, make it loose or dislocation with hand; But, many times, because people's hand strength is limited; This bottle cap is not easy to turn very much, can waste great amount of time under repeatedly attempting.

The utility model content

The technical matters that the utility model solved provides a kind of cap screwing device, and it is simple in structure, and is easy to use, thereby solves the problem in the above-mentioned background technology.

The technical matters that the utility model solved adopts following technical scheme to realize:

A kind of cap screwing device; Comprise threaded block, clamping bar and leading screw; The middle part of said threaded block offers internal thread hole, and said leading screw utilizes screw thread to be movably installed in the said internal thread hole, and said clamping bar middle part is hinged with tie rod; Said leading screw bottom limit mounting has the axle sleeve that rotates around said leading screw, and said tie rod is articulated on the said axle sleeve.

As a kind of improvement, said tie rod comprises back-moving spring, and the elasticity modulus of this back-moving spring must be enough big.

As a kind of improvement, said clamping bar is at least 3, is distributed on the said threaded block.

As a kind of further improvement, be connected with handle on the said threaded block.

Owing to adopted above structure, the utlity model has following beneficial effect:

The cap screwing device that the utility model provides utilizes leading screw pulling clamping bar, and clamping bar is clamped on the bottle cap; Utilize handle that bottle cap is turned on again, clamping bar has 3 at least, is distributed on the threaded block; Thereby can bottle cap be clamped actv., and the handle that is provided with on the threaded block can be exerted oneself very easily.

The utility model is simple in structure, has overcome people's the not enough shortcoming of hand strength in the conventional approach, can clamp bottle cap, has practiced thrift the time of uncapping, and is easy to use.

Description of drawings

Accompanying drawing is the utility model structural representation;

Among the figure: 1. threaded block, 2. clamping bar, 3. leading screw, 4. internal thread hole, 5. tie rod, 6. axle sleeve, 7. handle.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

Shown in accompanying drawing; A kind of cap screwing device comprises threaded block 1, clamping bar 2 and leading screw 3, and the middle part of said threaded block 1 offers internal thread hole 4; Said leading screw 3 utilizes screw thread to be movably installed in the said internal thread hole 4; Said clamping bar 2 middle parts are hinged with tie rod 5, and said leading screw 3 bottom limit mounting have the axle sleeve 6 that rotates around said leading screw 3, and said tie rod 5 is articulated on the said axle sleeve 6.In the present embodiment, said clamping bar 2 is 4, is distributed on the said threaded block 1, is connected with handle 7 on the said threaded block 1.

In addition, said tie rod 5 can adopt back-moving spring, and the elasticity modulus of this back-moving spring must be enough big.

Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical personnel in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
