Description

Electronic wrench structure

Technical field

The utility model is meant a kind of mode by power drives especially about a kind of electronic wrench structure, makes it can cut off the electronic wrench structure of iron wire or other article easily.

Background technology

Along with the general mood of completed knocked down products is in fashion day by day voluntarily at present, hand-held tool miscellaneous has become instrument indispensable in the completed knocked down products process, yet, in the process of present automation gradually, existing part hand-held tool successfully exploitation become electronic pattern, as electric drill etc.; But still have the hand-held tool of part not to be transformed into electronic pattern as yet, tonger is one of them, at present in the process of completed knocked down products, the user cuts off hard article such as metal wire usually by tonger, if when running into thicker metal wire, need expend bigger strength and time surely, this metal wire can be subtracted disconnected, and in the process of cutting off, more may cause user's injury; And for example plug in the process of artificial flower, the more indispensable instrument of tonger, and constantly take place because of the situation of using manual tonger and then damaging at present.

This shows that above-mentioned article commonly used still have many disappearances, real non-one kindhearted design, and demand urgently being improved.

Every shortcoming that the present utility model people derives in view of above-mentioned article commonly used is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully electronic wrench structure of the present utility model is finished in research and development finally.

The utility model content

The purpose of this utility model is to provide a kind of user of making to cut off the electronic wrench structure of metal wire easily.

Another purpose of the present utility model is to provide a kind of simple structure, processing procedure to reach easy to operate electronic wrench structure easily.

For achieving the above object, the technical scheme that the utility model adopted is: include a housing, a motor, a control circuit, console switch, first, second external member, two stands, two connecting rods and a cutter; Wherein, place, the bottom of this housing is connected with electric supply installation, and this electric supply installation provides power supply to motor; This console switch emergence goes out outside the housing, makes the keying of its controllable motor; This control circuit is connected with motor and console switch, when control circuit receives the signal of console switch, promptly can order about motor automatically and make forward and backward; The output shaft of this motor is connected with a train of reduction gears, and the output of this train of reduction gears is consolidated with a travelling gear, and this travelling gear is meshed with a driven gear, and is extended with a screw rod in the centre of driven gear; This first, second external member is screwed together on the screw rod; The upper and lower both sides of the rear end of this two stands and first external member are articulated, front end then is articulated with the rear end of two connecting rods respectively, this link rob front end place has a kink, this kink is articulated in the both sides up and down of second external member respectively, and the front end of connecting rod then is articulated with the both ends of cutter respectively; When control circuit receives console switch when being opening, promptly can order about motor just changes, and then the drive travelling gear rotates, but make travelling gear rotating band moving gear and screw rod rotate synchronously, cause first external member reach on the screw rod, and move after second external member, cause support and connecting rod can drive the mobile backward one stroke of cutter, when moving behind the cutter, can carry out the cutting nippers of article; When finishing the article cutting nippers, this control circuit can make the cutter involution, to carry out the action of cutting nippers once more ordering about the motor counter-rotating.

Electronic wrench structure provided by the utility model when comparing mutually with other common technology, has more following advantage:

1. the utility model can be cut off metal wire easily.

2. the utility model simple structure, processing procedure reach easy to operate easily.

3. the utility model can make it significantly increase torque value by the setting of train of reduction gears, and then makes the strength of cutting nippers increase.
