Abstract

The utility model discloses a chargeable screwdriver, comprising a casing, a motor (1), a speed change mechanism (2), an output shaft (3), and a battery (4); wherein, both the motor (1) and the speed change mechanism (2) are arranged in the casing, the motor (1) is connected with the output shaft (3) through the speed change mechanism (2), the battery (4) is electrically connected with the motor (1); the casing comprises a body (5) and a handle (6), a joint between the body (5) and the handle (6) divides the handle (6) into two parts, the left part is shorter than the right part; and the joint between the body (5) and the handle (6) sinks to form a finger station (7). By adopting the structure of the chargeable screwdriver of the utility model, the utility model improves the design of the chargeable screwdriver, and simultaneously combines somatological principles to improve construction of the handle, so that a left side of the handle is shorter than a right side of the handle, thereby facilitating holding of an operator, and enabling operation to be more convenient and faster.

Description

Rechargeable screwdriver

Technical field

The utility model relates to field of power tools, is a kind of rechargeable screwdriver specifically.

Background technology

Screwdriver is an instrument of screwing and dismantle screw, bolt.Along with the raising of production efficiency, traditional manual screw cutter can't satisfy the needs that people use.Therefore, electric screw is criticized and is begun to popularize and promote, but the electric screw of prior art criticizes great majority and all adopt household ac power, must could use in the occasion that AC power is arranged, and is inconvenient to carry, and the application that makes electric screw criticize is restricted.Afterwards; People have invented rechargeable screwdriver; This screwdriver generally comprises housing, motor, gear, output shaft and battery, and described motor, gear all are arranged in the housing, and motor is connected with output shaft through gear; Described housing comprises fuselage and handle, and described battery is electrically connected with motor.Like the disclosed number of patent application of State Intellectual Property Office is 200820084555.9 utility model patent " charging electric screwdriver ", and this patent adopts above-mentioned technology exactly.

Yet though above-mentioned prior art is superior to the conventional electric-powered screwdriver, but still have following defective: 1, handle is symmetrically distributed with respect to fuselage; Handle design is unreasonable, because the operator generally adopts the right hand when using screwdriver; The right hand is held handle; Operator's strength acts on the right of handle biglyyer, and about the part handle be symmetrically, so brought inconvenience to use; 2, rechargeable screwdriver is when screwing and dismantle screw, and speed and efficient is than higher, and this just requires operator's hand handle of holding with a firm grip, and hand generally is held in the junction of handle and fuselage during operation, and this position is not easy to hold with a firm grip.

The utility model content

The technical problem that the utility model will solve is the rechargeable screwdriver of a kind of handled easily is provided, holding easily with a firm grip.

The technical solution of the utility model is, a kind of rechargeable screwdriver of following structure is provided, and comprises housing, motor, gear, output shaft and battery; Described motor and gear all are arranged in the housing; Motor is connected with output shaft through gear, and described battery is electrically connected with motor, and described housing comprises fuselage and handle; The junction of fuselage and handle is with the handle separated into two parts, and left-hand component is shorter than right-hand component.

Adopt above structure; The utility model compared with prior art has the following advantages: adopt the utility model structure, when improving rechargeable screwdriver design, in conjunction with the anthroposomatology principle; Improve the structure of handle; The left side of handle is shorter than the right side, and taking of handled easily person held, and operates more convenient, quick.

As improvement, the recessed formation in the junction of described fuselage and handle finger position, set up the finger position after; The operator when using this product, the handle of firmly holding with a firm grip, the vibrational energy of rechargeable screwdriver when work is effectively controlled; Improved reliability of products, used convenient.

As improvement, the end of described fuselage is provided with relay indicating light, and fuselage surface is provided with some low grooves, like this, can intuitively show the duty of fuselage.

As improvement, the lateral surface of described handle is provided with the electric weight display board, like this, can the operation in intuitively the electric weight of electrolytic cell.

Description of drawings

Fig. 1 is the explosive view of the rechargeable screwdriver of the utility model.

As shown in the figure 1, motor, 2, gear, 3, output shaft, 4, battery, 5, fuselage, 6, handle, 7, the finger position, 8, relay indicating light, 9, the electric weight display board.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figure 1, the rechargeable screwdriver of the utility model comprises housing, motor 1, gear 2, output shaft 3 and battery 4; Described motor 1 all is arranged in the housing with gear 2; Motor 1 is connected with output shaft 3 through gear 2, and described battery 4 is electrically connected with motor 1, and described housing comprises fuselage 5 and handle 6; The junction of fuselage 5 and handle 6 is with handle 6 separated into two parts, and left-hand component is shorter than right-hand component; The described left side and the right are relative, when the operator holds the handle of screwdriver with the right hand, are the left side near thumb one side, are the right near little finger of toe one side, just the convenience in order to explain.

Described fuselage 5 and recessed formation finger position, the junction of handle 67,7 places, finger position than fuselage parts of fine, for operator's hand stays the space of holding tight in one's hands.

The end of described fuselage 5 is provided with relay indicating light 8, and fuselage 5 surfaces are provided with some low grooves, and relay indicating light 8 mainly is the mode of operation that is used to show screwdriver; Described end is meant that the end of fuselage 5 promptly near the output axle head, has reflected the duty of rechargeable screwdriver effectively.

The lateral surface of described handle 6 is provided with electric weight display board 9, and when being full of electricity, electric weight display board 9 is full lattice; And consume along with using, electric weight slowly reduces, when electric weight is about to exhaust; Then electric weight display board 9 is shown as sky, at this moment, then should in time charge; In order to avoid influence is used, also warning reminding can be set simultaneously.

The operation principle of the utility model is following: adopt the utility model structure, when improving rechargeable screwdriver design, in conjunction with the anthroposomatology principle; The operating habit that meets people, when holding handle, the active force of staff concentrates on handle the right mostly; Through improving the structure of handle; The left side of handle is shorter than the right side, and taking of handled easily person held, and operates more convenient, quick.

Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.The utility model not only is confined to above embodiment, and its concrete structure allows variation, can be according to using design like the depth of finger position; The electric weight display board of the lateral surface of handle 6 is meant the side near human body, but is not limited to above-mentioned installation site.In a word, all various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
