Description

Electric tool with two power sources

Technical Field

The invention relates to the technical field of electric tools, in particular to an electric tool with two power sources.

Background

It is well known that damage to current power tools during use is caused primarily by the power tool being in an overloaded condition. The existing electric tool is influenced by the size of a holding part, the internal arrangement space is limited, and the motor parameter cannot be selected too much, so that the output power is limited. In many cases, in order to pursue the working efficiency, the user frequently makes the electric tool in overload operation, which causes damage to the motor part inside the electric tool and affects the service life. Due to the above problems, there is a need for improvement.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the electric tool with two power sources, which has the advantages of simple circuit, compact structure and convenient manufacture, can improve the working efficiency by times, greatly reduces the probability of motor damage, and reduces the use and maintenance cost.

The technical scheme adopted by the invention for solving the technical problems is as follows: an electric tool with two power sources comprises a body, an output shaft, a switch component used for controlling the starting of a motor, a power line, a gear box body and a driving gear, wherein the gear box body and the driving gear are arranged in the body, the driving gear and the output shaft are fixedly arranged to drive the output shaft to rotate, two motors are arranged in the body and comprise motor gears, the motor gears of the two motors are meshed with the driving gear and keep rotating in the same direction, and the two motors drive the output shaft to rotate simultaneously.

In the above technical solution, preferably, the body includes two handles, and the two motors are respectively disposed in the two handles. Set up like this, can guarantee arranging of motor, separately arrange two motors moreover and also further guaranteed the radiating effect when using simultaneously, and the use of gripping of two handles accords with operating personnel's use custom, can grip electric tool better, guarantees the safety in utilization.

In the above technical solution, preferably, the angle between the two handles is 0 to 180 degrees. Further, the angle between the two handles is 90-115 degrees. Set up like this, accord with operating personnel and use the custom, can hold electric tool better, guarantee the safety in utilization.

In the above technical solution, preferably, the switch member is provided on one of the handles. The operator can hold the two handles with two hands respectively and use one hand to carry the control switch component, so as to control the running state of the motor.

In the above technical solution, preferably, the driving gear and the motor gear are disposed in the gear box body together. Set up like this, through gear box can play dustproof guard action to driving gear and motor gear, guarantees gear clearance fit's reliability.

In the above technical solution, preferably, the two motors are arranged in parallel. The arrangement ensures that the power of the two motors is concentrated on the same output shaft and drives the working head to move.

The invention has the beneficial effects that: the invention adopts the same switch component and power cord to control two motors, the two motors respectively drive respective motor gears to be simultaneously meshed with the driving gear and drive the driving gear to rotate, and the driving gear drives the output shaft to rotate. Therefore, the power output of the two motors is concentrated on one output shaft and drives the working head to move, the purpose of increasing the output power is achieved, the working efficiency is greatly improved, the probability of motor damage is reduced, and the use and maintenance cost is reduced.

Drawings

The invention is further illustrated with reference to the following figures and examples.

Fig. 1 is a schematic view of the internal structure of the present invention.

Fig. 2 is a left side view of fig. 1.

In the figure, 1, a motor gear, 2, an output shaft, 3, a driving gear, 4, a gear box body, 5, a first handle, 6, a switch component, 7, a second handle and 8, a power line.

Detailed Description

Referring to fig. 1-2, an electric tool with two power sources comprises a body, an output shaft 2, a switch component 6 for controlling the start of a motor, a power cord 8, a gear box 4 and a driving gear 3 which are arranged in the body, wherein the driving gear 3 and the output shaft 2 are fixedly arranged to drive the output shaft 2 to rotate, the body comprises a first handle 5 and a second handle 7, an included angle α is formed between the first handle 5 and the second handle 7, and the value of α is 100 degrees. Two motors (not shown in the figure) are arranged in the body, the two motors are respectively arranged in the two

handles

5 and 7, and the two motors are arranged in parallel. The switch part 6 and the power cord 8 are arranged on the second handle 7 to control the use state of the motor. The motor comprises a motor gear 1, the driving gear 3 and the motor gear 1 are jointly arranged in the gear box body 4, the motor gears 1 of the two motors are meshed with the driving gear 3 and keep rotating in the same direction, and the two motors simultaneously drive the output shaft 2 to rotate. The driving gear 3 and the motor gear 1 are both conical gears, so that the rotating axis of the motor gear 1 is controlled to be perpendicular to the rotating axis of the output shaft 2.

The working process of the invention is as follows: the user grips first handle 5 and second handle 7 with both hands, through opening switch part 6 control first motor and the second motor on the second handle 7 and start simultaneously, first motor and second motor drive driving gear 3 through respective motor gear 1 syntropy and with fast and rotate, drive output shaft 2 through driving gear 3 and rotate, install the working head on the output shaft 2, can accomplish different work through the working head of chooseing for use different functions.
