Description
The utility model relates to a kind of portable electric power tool, and a strength member of compound saw in the working mode change operating process, is used to protect sawtooth not touch the built-in guard hood of combined saw of staff, protection personal safety.
Compound saw can utilize top platform to cut operation as platform, and at this moment fuselage is pressed downwardly onto the end, and is parallel to base, timber can be placed on the platform, utilizes sawtooth timber to be dissectd blocks of.The operation of can cutting sth. askew again of compound saw, at this moment fuselage lifts and the angle that tilts, and utilizes sawtooth tubing, profile shapes can be sawn into a section.
In the real work, especially compound saw changes over during cutting on table from cutting sth. askew in the operating process of carrying out working mode change, at this moment if the user operates because of carelessness, dangerous accident will take place.For guaranteeing the safety of the person and equipment, generally adopt on the work top below compound saw, place an auxiliary protective cover earlier, sawtooth is covered entirely, and then operation.But often some user dislikes trouble, and dislikes just operating with auxiliary protective cover, does not therefore just reach protective action.
And some compound saw adopts mandatory means for making its energy safety operation, promptly utilizes inter-agency chain effect.If want working mode change, just can carry out after must will assisting protective cover to put.Though guaranteed safety like this, the time, if auxiliary protective cover has been lost, then this compound saw just can not carry out conversion operations, cuts function thereby make this compound saw lose platform, therefore neither a good method with after long.
The purpose of this utility model is to provide a kind of built-in guard hood of combined saw, is installed on the fuselage, in the working mode change process, can control its relieving or gathering, plays protective action, and is easy to use, reliable, safe, can not lose again.
The utility model is achieved in that built-in guard hood of combined saw, described protective cover is fused by dead man that has stage clip and the dead man seat that has stage clip, and the dead man handle that connects and composes with dead man cover, skidding, handle, with by the fork that is connected on the fork pin, respectively with the left and right protective plate that has left and right connecting rod, the rotating mechanism that the constitutes by an active connection composition that is connected.
The utility model is compared with prior art: because of this protective cover is mounted in framework cover cap and the framework,, in the process of working mode change, can put down automatically or pack up, sawtooth is covered entirely for built-in, and simple to operate, easy to use.Avoid the generation of protective cover loss phenomenon, guaranteed operator's safety.
Therefore the action of protective roof structure and other structure all has relation chain, interlock again, and therefore can not be damaged because of maloperation equipment and the accident that causes personal injury use reliable, safety, can reach the purpose of protection fully.

Fig. 2. Fig. 1 handle 1 place's enlarged drawing;
Fig. 3. the vertical view of Fig. 1;
Fig. 4. structural representation of the present utility model (state of cutting sth. askew);
Fig. 5. Fig. 4 handle 1 place's enlarged drawing;
Fig. 6. the vertical view of Fig. 4.
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Left side protective plate 12, right protective plate 11 have through hole on being, lower limb has the rectangular slab of positioning disk 14, and the top edge of right protective plate 11 also has a breach.
In the middle of the dead man cover 6 through hole is arranged, respectively have lock slots 4,4 ' symmetry, two circular arcs on the two halves circular side wall, a caulking groove is respectively arranged on the two ends, bottom surface.
Dead man 22 is a shape, and there is screw thread the upper end, and there is through hole the lower end.
The front end that dead man cover 6 utilizes two caulking grooves on it and corresponding skidding 2 to be fixed on framework cover cap 8.
The dead man 22 that has stage clip 21 is placed in the dead man seat 19, and with stop pin 5 the dead man seat 19 of dead man 22 with band stage clip 3 is linked into an integrated entity.Dead man 22 and dead man seat 19 pass the through hole in dead man cover 6 and the skidding 2, are fixed on the screw thread of dead man 22 ends to constitute the dead man handle on the handle 1.
There is through hole at a left side connecting rod 9, right connecting rod 13 two ends, and also fix a limited post on the right connecting rod 13, and left connecting rod 9 is connected with joint pin on framework liner plate 16 inwalls, and are the fulcrum rotation with it.
Right connecting rod 13 is connected with output shaft bearing hole on the framework 17, and is that fulcrum rotates with it.The end in addition of a left side connecting rod 9, right connecting rod 13 and two arms of fork 10 openends flexibly connect with left protective plate 12, right protective plate 11 with bearing pin or rivet, spring 20 respectively.
Fork pin 7 passes the through hole on the fork 10, and two ends are separately fixed on framework 17 and the framework cover cap 8, constitutes the rotating mechanism of protective cover.
The dead man handle is utilized dead man seat 19 on it, be screwed on the fork 10 of protective cover rotating mechanism, connect into whole protective cover.
During use, the operation if the user cuts sth. askew, at first the distribution that will pull out on the compound saw unlocks, fuselage is lifted, and the dead man handle pulled out, stop pin 5 on it is pulled out from lock slots 4, and to pressing down, at this moment the fork 10 of connected rotating mechanism just around the rotation of fork pin 7 clockwise directions, drives connected left protective plate 12 simultaneously, right protective plate 11, left side connecting rod 9, right connecting rod 13 is synchronized with the movement, and around fulcrum do rotation counterclockwise everywhere, when left protective plate 12, after right protective plate 11 turns over 90 °, a left side, right protective plate just is collected in front fuselage inside, and the dead man handle also automatically downwards, stop pin 5 on it is locked in the lock slots 4, and this moment, compound saw just was operated in the operational mode state of cutting sth. askew, position as shown in Figure 2.
If will cut operation as platform, the dead man handle is pulled out, stop pin 5 on it is pulled out from lock slots 4 ', and upwards rotate, connected rotating mechanism is done rotation counterclockwise around fork pin 7, drive connected left protective plate 12 simultaneously, right protective plate 11 is done the clockwise direction rotation, protect state-transition by non-protection state to sawtooth, when left protective plate 12, after right protective plate 11 turns over 90 °, spacing owing to the limited block effect on the right connecting rod 13, the dead man handle also makes progress automatically simultaneously, stop pin 5 is locked in the lock slots 4, left protective plate 12, it is other that right protective plate 11 just is placed on sawtooth 18, protects following sawtooth 18, again fuselage is pressed downwardly onto the end, and on fuselage, pushes the distribution locking.At this moment compound saw has converted platform cut operation mode to.The positioning disk 14 of left protective plate 12, right protective plate 11 lower ends has embedded in the groove on the compound saw work top 15 saw kerf plates at this moment, and it can not moved, and protection puts in place fully, as shown in Figure 1 the position.
