Abstract
An electric adjustable wrench mainly comprises a wrench handle, a fixed wrench tooth, an adjustable wrench tooth and a rotating wheel shaft connected with the adjustable wrench tooth, wherein a battery seat with a battery arranged inside is arranged in the wrench handle, a direct current motor is arranged at the front part of the battery seat, and a motor shaft extends forwards and is connected with the rotating wheel shaft with an end gear through a bevel gear; the bevel gear is sleeved on the motor shaft, and a supporting spring for enabling the bevel gear to prop against the rotating wheel shaft is arranged at the rear part of the bevel gear; a contact breaker switch connected with the power circuit in series is arranged on the edge of the contracted supporting spring; the automatic feeding device has the characteristics of simple structure, convenience in use, safety, reliability, wide application range, capability of reducing labor intensity, effectively improving working efficiency and the like.
Description
Technical field
The utility model relates to a kind of instrument that securing members such as nut, nut are installed and removed, belong to the spanner type electric tool.
Background technology
Existing adjustable wrench is as a kind of instrument that securing members such as nut, nut are installed and removed, it mainly is mechanical structure, by spanner handle, fixedly bolt die, movable bolt die and the runner shaft that links to each other with movable bolt die are formed, by usefulness hand rotating wheel axle, thereby the folding of promotion spanner tooth is operated.Some must with on the work position that could operate of gloves, its use will be restricted because with the hand of gloves are the positions that are difficult to rotating wheel axle stably and determine the bolt die mouth.Simultaneously when practical operation at ordinary times, to some nut and small size nuts at corner location, or stretch the narrow space of not entering at hand at all, or hand is to put in, but the position of nut has object to block operator's sight line, and at this time the operator can only operate with feeling, thereby can influence operating efficiency, and, make nut angle tooth circle cause permanent damage easily because bolt die folding degree is not in place.In addition because manual adjustable wrench is to promote runner by finger to regulate moving of monkey wrench, the strength of considering finger is limited, therefore manual bolt die is when the processing design, need reserve than large space and slit the linking between runner shaft and the movable bolt die, so that the rotation of finger, and this loose gap has just caused the loosening degree of the movable bolt die of spanner to become big, when it twists some difficult nuts of twisting, can cause Mao Jiao to press the permanent damage of circle and nut can't be unscrewed.
Summary of the invention
The purpose of this utility model is to overcome not existing of above-mentioned existence, promotes runner shaft by driven by motor and with this as power and provide a kind of, and then the electric adjustable wrench that movable bolt die is moved forward and backward.It is mainly by spanner handle, fixedly bolt die, movable bolt die and the runner shaft that links to each other with movable bolt die are formed, be provided with the battery tray of internal battery in the described spanner handle, the front portion of battery tray is equipped with direct current generator, and motor shaft protracts and links to each other with the runner shaft that has end gear by a bevel gear.
Described bevel gear is socketed on the motor shaft, and is provided with at the rear portion of bevel gear and makes it withstand the support spring of runner shaft.
Also be mounted with a contact disconnect that is in series with power circuit on the described support spring limit.Comment the utility model to go for narrow and small, special environment and carry out work, applied widely, can singlehanded operation, increase work efficiency, reduce labour intensity, have simple in structure, easy to use, safe and reliable, characteristics such as effectively increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is machine operation power supply catenation principle figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model is mainly by spanner handle 1, fixedly bolt die 2, movable bolt die 3 and the runner shaft 4 that links to each other with movable bolt die are formed.Be provided with the battery tray 5 of internal battery in the spanner handle 1, the front portion of battery tray 5 is equipped with direct current generator 6, and motor shaft 7 protracts and links to each other with the runner shaft 4 that has end gear 9 by a bevel gear 8.Described bevel gear 8 is socketed on the motor shaft 7, loosening gap can be arranged between the two, and is provided with the support spring 10 that makes it withstand runner shaft 4 and mesh with end gear 9 at the rear portion of bevel gear 8.On the limit of support spring 10, also be mounted with a contact disconnect 11 that is in series with power circuit.During use, press the power switch K1 on the spanner handle, motor 6 rotations, promoting movable bolt die 3 by bevel gear 8, runner shaft 4 draws close to fixing bolt die 2, when movable bolt die 3 withstood that fixedly bolt die 2 can not march forward, this moment, the operator unclamped power switch K1, and then motor stops operating.If forgetting, the user unclamps power switch K, bevel gear be because of can't promoting runner shaft so, and can only oppress the support spring of bottom to bottom offset, when bevel gear is pressed downwardly onto contact disconnect 11 on support spring 10 limits, circuit also just interrupts at once, the motor stall.Also have reverse electrical source K switch 2 in power circuit, see shown in the accompanying drawing 2, its course of work has played the safeguard protection effect in fact with aforesaid the same substantially, described here contact disconnect 11.Circuit shown in Fig. 2 is a custom circuit, and selected power switch K1, K2 are the push type ganged switch, is to break the formula switch and contact disconnect 11 is selected for use, and battery can be selected dry cell for use, also can select battery for use, and they can be rechargeable batteries.
