Abstract
The utility model discloses a safe electric saw, which comprises a motor and a circular saw, the motor is connected with the circular saw through an eccentric connecting rod mechanism, the reciprocating rotation angle of the circular saw is between 0 degree and 40 degree under the effect of the eccentric connecting rod mechanism; the eccentric connecting rod mechanism comprises an eccentric wheel connected with a rotating shaft of the motor, a swing rod connected with the circular saw and a connecting rod connected between the eccentric wheel and the swing rod; for the eccentric connecting rod mechanism is arranged between the motor and the circular saw for connecting in the safety electric saw, the circular saw can conduct a reciprocating rotation action within a smaller angle when the motor rotates by one circle in which human is not injured within the instinct reaction period from touching action to the action of keeping away while human is injured in the prior conventional saw rotating directionally, therefore, the utility model is safe electric saw without injuring human hand under a slight touch.
Description
Technical field
The utility model discloses a kind of electric saw, is specifically related to a kind of safe circular saw cutter electric saw of not hindering hand that touches.
Background technology
The saw cutter is one of people's daily life wood processing apparatus commonly used, and miniature circular saw cutter electric saw is because its portability is subjected to people's extensive welcome, and more especially as student's work class etc., most little plank is processed and all adopted this miniature charging electric saw.Because saw blade is sharp and at a high speed rotation, no matter be that the skilled worker operates this or beginner, just be easy to touch because of carelessness the saw blade of working unless you give your whole attention to it and injured, therefore there is great potential safety hazard in traditional electric saw.
Summary of the invention
The utility model improves a kind of safe electric saw of not hindering hand that touches at above-mentioned deficiency.
In order to achieve the above object, the utility model is by the following technical solutions:
Safe electric saw described in the utility model comprises motor and circular saw cutter, and described motor is connected with the circular saw cutter by an eccentric rod gear; Described circular saw cutter in the angle of back and forth rotating under the effect of eccentric rod gear between 0 ° to 40 °.
Described eccentric rod gear comprises that fork and that an eccentric wheel, that is connected in machine shaft is connected in the circular saw cutter is connected in the connecting rod between eccentric wheel and the fork.
It also comprises the operating portion that a base plate and is articulated in base plate and has handle.
Described motor and circular saw cutter are installed on the operating portion.
Described circular saw cutter is covered with a detachable protecting sheathing outward.
In the handle of described operating portion power supply is housed.
Described power supply is that rechargeable battery also can be low-voltage alternating current power supply.
Be provided with an elasticity locking mechanism between described base plate and the operating portion.
The utility model adopts above technical scheme that following advantage is arranged:
Safe electric saw described in the utility model is owing to be provided with eccentric rod gear and be connected between motor and circular saw cutter, motor rotates a circle the circular saw cutter is back and forth rotated in less angle, makes the people can be not injured as the existing directed routine saw cutter that rotates of touching in the time in touching to the natural reaction of leaving the saw cutter.Therefore the utility model is a kind of safe electric saw of not hindering hand that touches.

Schematic diagram behind Fig. 4 the utility model installation protecting sheathing.
The utility model is described in further detail below in conjunction with drawings and Examples:
The specific embodiment
Safe electric saw described in the utility model shown in Fig. 1,2,3 and 4, comprise that a base plate 2 and is articulated in base plate 2 and has the operating portion 1 of handle 15, motor 11, circular saw cutter 12 and power supply 13 are installed on the operating portion 1, power supply is that rechargeable battery and its are installed on the handle 15, handle 15 is provided with switch 16, and described motor is connected with circular saw cutter 12 by an eccentric rod gear 14; As shown in Figure 3, described eccentric rod gear 14 comprises that fork 143 and that an eccentric wheel 141, that is connected in machine shaft is connected in circular saw cutter 12 is connected in the connecting rod 142 between eccentric wheel 141 and the fork 143; Described circular saw cutter in the angle of back and forth rotating under the effect of eccentric rod gear 14 between 0 ° to 40 °; For safety is considered, be covered with detachable protecting sheathings 17 outside the circular saw cutter 12 as shown in Figure 4; Be provided with an elasticity locking mechanism 3 between base plate 2 and the operating portion 1 for making things convenient for of operating as shown in Figure 2, when the safety electric saw is idle, can mention, prevent that circular saw blade from contacting with loading end and do colored loading end by the hadle operating portion.
Should be noted that power supply of the present utility model also can adopt low-voltage alternating current power supply.
Safe electric saw described in the utility model is owing to be provided with eccentric rod gear and be connected between motor and circular saw cutter, motor rotates a circle the circular saw cutter is back and forth rotated in less angle, motor speed is between～10000 rev/mins of 6000 commentaries on classics during work, the angle that the circular saw cutter back and forth rotates is tightly about 30 °, make the people touch in the reaction time of leaving the saw cutter not and can rotate injuredly because of the orientation that routine is sawed cutter, so the utility model be particularly suitable for the lower student of awareness of safety or the beginner uses.
