The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Be the electric tool of the embodiment of the present invention as illustrated in fig. 1 and 2, it is a kind of reciprocating saw, comprises main body 1, battery 3, clamping device 4 and saw blade 5, described main body 1 is provided with grip part 2, battery 3 is arranged on main body 1 rear end, is used for driving the motor in main body 1, and driven by motor saw blade 5 moves reciprocatingly.The front end face 11 of described reciprocating saw is provided with baffle plate 6, in the time taking off clamping device 4 and use reciprocating saw, can rely on baffle plate 6 against living material to be cut.Described reciprocating saw is provided with two baffle plates 6 that lay respectively at saw blade 5 both sides.
As shown in Figures 1 to 4, clamping device 4 comprises support 42 and holding frame 41, and support 42 is provided with chute 48, and holding frame 41 connects with spacing by connecting portion 412 and chute 48.Described connecting portion 412 can be any mode of prior art with the docked mode of chute, and the present embodiment adopts screw 413 to connect.Described holding frame comprises supporting leg 411, and supporting leg 411 roughly becomes inverted V-type, and it is used for material to be cut to carry out spacing, and what the peristome between supporting leg was material to be cut accommodates region, zigzag contact site is set on supporting leg and makes clamping more firm.In the time of cutting, for example cut branch, branch is placed between the sawtooth of holding frame 41, and along with saw blade incision branch, holding frame can move by chute thereupon, thereby guarantees that saw blade can complete cutting.Described support 42 is provided with two extensions that are oppositely arranged 423, and described chute 48 is arranged on extension 423.Described clamping device 4 also comprises linking arm 45, return unit 44 bearing pins 49, linking arm 45 two ends are provided with axis hole 451, linking arm 45 two ends are pivotally connected respectively at support 42 and holding frame 41, linking arm 45 is connected by the first hinge portion 46 with support 42, and linking arm is connected with the second hinge portion 47 with holding frame 41.The first hinge portion comprises bearing pin 49, and bearing pin 49, through the pin-and-hole on support 42 and linking arm 45, is assembled together linking arm 45 and support 42, and support and linking arm can be rotated around bearing pin place axis.The second hinge portion comprises screw 414, between linking arm 45 and holding frame 41, is connected and can be relatively rotated by screw 414.Return unit 44 described in the present embodiment is torsion spring, and return unit 44 is set on bearing pin 49, and first end 441 is connected with the second hinge portion 47.The effect of return unit 44 is to provide a restoring force, restoring force acts on holding frame 41, make that holding frame is better must be clamped in cut material, simultaneously in the time that holding frame departs from cut material, the stressed meeting of holding frame automatically reverts to initial position, as shown in Figure 1, now holding frame is subject to restoring force effect connecting portion to arrive chute bottom to initial position.Further, be separable assembling in order to realize between clamping device and main body, described clamping device 4 also comprises clip 43, and clip 43 is arranged on support 42 by bearing pin 49, the second end 442 of return unit is resisted against on clip, and therefore clip is subject to the restoring force of return unit.Described support 42 is provided with inserted sheet 421 and spacing hole 422, in the time that needs are arranged in reciprocating saw main body by clamping device 4, inserted sheet 421 is inserted to the socket 61 on baffle plate 6, snap fit 431 on clip 43 snaps in bayonet socket 63, the restoring force of elastic component makes grab catch on baffle plate, now the limiting section 62 of baffle plate top inserts in the spacing hole 422 on support, completes assembling.Between clamping device 4 and baffle plate 6, upper and lower all arranges spacingly, and what make that clamping device can be firm connects with reciprocating saw main body.In the time that needs take off clamping device, operation clip 43, departs from bayonet socket 63 with snap fit after clip 43 turns an angle, and then support 42 is extracted from baffle plate, realizes and departing from.On clip 43, be also provided with positive stop end 432, prevent that clip is subject to reset force effect rotational angle excessive.In the present embodiment, described clamping device 4 is about saw blade place plane symmetry, and therefore chute, holding frame, supporting leg are all oppositely arranged.
As illustrated in Figures 5 and 6, according to the difference of the performance indications such as the diameter of cutting object, can change the motion path of clamping device by changing chute 48, therefore chute 48 can be designed to various shapes.In embodiment in Fig. 5, chute 48 is made up of straightway 481 and segmental arc 482, and therefore the motion path of holding frame is that arc and rectilinear motion combine.In the another kind of embodiment of Fig. 6, chute 48 ' only has straightway chute, and therefore the motion of holding frame is to move up and down.
Clamping device of the present invention is spacing, simple in structure by chute, and has reduced the size of clamping device, effectively reduces cost.It is pointed out that above-mentioned preferred embodiment is only explanation technical conceive of the present invention and feature, its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
