Abstract

The utility model relates to a portable electric circular saw which comprises a casing, a motor, a circular saw blade, a handle, a power switch and a locking switch. The end part of the motor is provided with an upper part protective frame cover for the circular saw blade, and a lower part movable protective cover which can be opened and reset in a rotary way of the circular saw blade. The upper part protective frame cover or the casing is provided with a reference bottom plate which can adjust lifting and angle (the included angle of the planes of circular saw blade and the reference bottom plate) corresponding to the circular saw blade. The reference bottom plate is provided with a length backup plate. Backing plate. The portable electric circular saw has the advantages of convenient portability and safe operation, and cuts and saws the wood with prescribed length, depth (diameter) and angles.

Description

Electric hand ring saw

The utility model belongs to a kind of timber and adds wood machinery.

Existing electric circular saw all has fixing frame, all need to be fixed on one local could process operation, portable timber is electronic to be cut the timber that the saw tool has only chain-type and cuts down saw, but its only is suitable for and fells timber, is not suitable for using in timber processing at ordinary times.

The purpose of this utility model is the Portable electric cicular saw that a kind of suitable timber processing will be provided, and not only palm top is convenient for it, and the degree of depth, angle and the length of cutting saw can be regulated.

The utility model is realized by following structure; a kind of Portable electric cicular saw; comprise casing, motor, saw blade, handle, power switch; locking switch; its main points are that the motor end is provided with the top fender bracket cover of saw blade and rotatable unlatching and the bottom movable protective shield of the saw blade that resets; the benchmark base plate of relative saw blade liftable and angle adjustable (angle mutually that saw blade is mutual with plane, benchmark base plate place) is housed on top fender bracket cover or casing, can be provided with the length backup plate on the benchmark base plate.

This Portable electric cicular saw is because be provided with the top fender bracket cover and the movable bottom movable protective shield that rotarily opens and reset of saw blade, so the portable sawmilling material that cuts is safe and reliable in the motor end; It is provided with the benchmark base plate of relative saw blade liftable and angle adjustable in addition, it can cut the degree of depth or the diameter of saw according to the timber needs, regulate the height of saw blade relative datum base plate, cut the angle of saw according to the timber needs, regulate the angle between benchmark base plate and the saw blade,, regulate the length backup plate on the benchmark base plate according to the length that the timber needs cut saw, so this Portable electric cicular saw is easy to operate, and can adapt to the above-mentioned saw requirement of cutting.

The most preferred embodiment represented below in conjunction with accompanying drawing 1-6 is further described the utility model.

Accompanying drawing 1---(1)-casing in 6; (2)-motor; (3)-saw blade; (4)-handle; (5)-and power switch, (6)-locking switch, (7)-top fender bracket cover; (8)-the bottom movable protective shield; (9)-and the benchmark base plate, (10)-movable interlinkage, (11)-lift adjustment frame; (12)-round pin; (13) (14) (15) (16)-tight fixed bolt, (17)-angular adjustment frame, (18)-length backup plate; (19)-and turning arm, (20)-location calibrating jig.

Accompanying drawing 1---6 represented embodiment are by casing (1), motor (2), and saw blade (3) (saw blade can be installed temporarily), handle (4), power switch (5), locking switch (6) is formed.The end of motor (2) is provided with the top fender bracket cover (7) of saw blade (3) and rotatable unlatching and the bottom movable protective shield (8) of the saw blade that resets.One end of benchmark base plate (9) is fixed on the top fender bracket cover (7) by movable interlinkage (10), and the other end links movingly with the round pin (12) that is fixed on the lift adjustment frame (11).Lift adjustment frame (11) has lifting groove and falling head scale, and lift adjustment frame (11) is by tight fixed bolt (13) and top fender bracket cover (7) location and binding.Benchmark base plate (9) can rotate around movable interlinkage (10), round pin (12), and by this rotate regulate and saw blade (3) between angle, regulate angle after, locate by angular adjustment frame (17).Angular adjustment frame (17) is made up of the turning arm (19), location calibrating jig (20) and the tight fixed bolt (14) that are separately fixed on top fender bracket cover (7) and the benchmark base plate (9).Screwing tight fixed bolt (14) after the angle that benchmark base plate (9) is transferred to and saw blade (3) needs gets final product.Benchmark base plate (9) is provided with adjustable length backup plate (18), and length backup plate (18) is carved with the scale of expression collapsing length, and length backup plate (18) is set up the back and located by the tight fixed bolt (15) on the benchmark base plate (9).

The represented Portable electric cicular saw of this embodiment is to use with following procedure operation.Unclamp tight fixed bolt (13) (14) (15); according to cutting sawmilling material needs; the degree of depth that promptly needs; angle; length; regulate height that benchmark base plate (9) descends and and saw blade (3) between angle; regulate length backup plate (18) and pull out length; screw tight fixed bolt (13) (14) (15) then; hold handle (4) like this; turn on the power switch (5) and locking switch (6); the head of benchmark base plate (9) can be pushed away the saw operation forward against timber, and bottom movable protective shield (8) is pushed the rotation direction clockwise direction thereupon and rotates unlatching.Cut saw and finish, with saw blade (3) when withdrawing from, bottom movable protective shield (8) is spinning reduction in the counterclockwise direction automatically.As sawmilling material from top to bottom, then earlier bottom movable protective shield (8) is up rotarily opened, screw behind the tight fixed bolt (16) line operate again.

Can find out from structure and the operation of this embodiment, Portable electric cicular saw, easy to carry, handling safety is reliable, can cut the timber of saw specific length, the degree of depth and angle.
