The specific embodiment
As shown in Figure 1 and Figure 2; the safety guard of a kind of cutting knife type trimmer of the utility model comprises a base 10 and a cut-off knife 30; a fixed blade 20 of fixed installation and an axostylus axostyle 12 on the base 10; cut-off knife 30 can rotate around axostylus axostyle 12, and the front end of cut-off knife 30 is provided with a long slot bore 32 and 12 movable cooperations of axostylus axostyle, when cut-off knife 30 cuts action; cut-off knife 30 is when axostylus axostyle 12 rotates; also slide with respect to axostylus axostyle 12 front and back, thus make cut more laborsaving so that cut more paper.
On the basis of said structure, the utility model also comprises with lower member:
One promotes bar 42, the parallel outside that is fitted in cut-off knife 30, and the front end that promotes bar 42 is provided with a circular hole 421, and circular hole 421 is enclosed within on the axostylus axostyle 12 rotationally, and the side that promotes bar 42 is provided with outward extending pushing pin 422;
At least one cutter retaining plate, be provided with two in the present embodiment, cutter retaining plate 51 and back cutter retaining plate 52 before being divided into, cutter retaining plate is positioned at the outside that promotes bar 42, cutter retaining plate 51,52 is provided with the chute 55,56 of inclination, and the front end of chute 55,56 (near an end of axostylus axostyle 12) is higher than rear end (away from an end of axostylus axostyle 12); In the present embodiment, every cutter retaining plate is provided with two chutes, accordingly, promotes to be provided with four pushing pins 422 altogether on the bar 42, and each pushing pin 422 inserts in the chute 55,56, and the two ends of cutter retaining plate respectively are provided with two columniform portions 54 that wear;
And at least two gripper shoes 53, each needs a gripper shoe two ends of every cutter retaining plate, therefore has under the situation of two cutter retaining plates at present embodiment, and gripper shoe 53 should have four.The upper end of gripper shoe 53 is fixed on the knife back of cut-off knife 30, and gripper shoe 53 and cut-off knife 30, cutter retaining plate the 51, the 52nd are vertical, and every gripper shoe 53 is provided with two elongated holes 531 (seeing Fig. 3, Fig. 4); The portion that wears 54 on every cutter retaining plate is inserted in the elongated hole 531, and can slide in elongated hole 531.
In the utility model, when the operator holds handle of a knife 33 and cuts,, also drive the cutter retaining plate 51,52 that is installed on the cut-off knife 30 and slide simultaneously because cut-off knife 30 slides before and after also having when rotating; Have only rotation and not slip and promote bar 42 with respect to axostylus axostyle 12.Therefore; promoting to produce relative slip between bar 42 and the cutter retaining plate 51,52; simultaneously, the pushing pin 422 that promotes on the bar will slide in the chute 55,56 on cutter retaining plate relatively, because the front end of chute 55,56 is higher than the rear end; when cut-off knife is opened (lifting); as shown in Figure 1, pushing pin 422 is positioned at the front end of chute 55,56, makes cutter retaining plate 51,52 be in a lower position; thereby blade 31 is covered, play the safeguard protection effect.And along with cut-off knife 30 rotates, pushing pin 422 can relatively slide to the rear end of chute 55,56, cutter retaining plate 51,52 is lifted, to expose blade 31, so that cut (as shown in Figure 8).
Have only a monoblock cutter retaining plate also can reach above-mentioned protective effect even if be appreciated that according to the above description.But present embodiment is divided into forward and backward two with cutter retaining plate, is to expose blade for segmentation, plays the better protection effect.As shown in Figure 5, chute on the preceding cutter retaining plate is divided into three sections, it comprises oblique a section 552 of being obliquely installed, be positioned at the breeze way 551 of oblique section front end and be positioned at the following segment 553 of oblique section rear end, and breeze way 551 parallels with following segment 553, and breeze way 551 is positioned at the top of segment 553 down.As shown in Figure 6, the chute on the back cutter retaining plate is divided into three sections too.In the present embodiment, the length of cutter retaining plate chute breeze way 551 before the length of back cutter retaining plate chute breeze way 561 is greater than, then under the cutter retaining plate chute length of segment 563 less than the length of segment 553 under the preceding cutter retaining plate chute, like this, as shown in Figure 7, after cut-off knife rotates certain angle, pushing pin 422 in preceding cutter retaining plate 51 chutes at first enters oblique section 552, preceding cutter retaining plate 51 is lifted, and one section blade 31 of front end exposes, thereby can utilize this section blade to cut a sheet of paper; And at this moment, the pushing pin 422 in back cutter retaining plate 52 chutes still is positioned at its breeze way 561, and back cutter retaining plate 52 still remains on original position, and one section blade of rear end is still being protected by it, does not expose, and therefore protects better effects if.Have only when cut-off knife and continue to rotate, in the time of will using the one section blade in rear end and cut a sheet of paper, this section blade just can expose.
As shown in Figure 3, Figure 4, the lower end of cutter retaining plate 51,52 tilts, the lower end of cutter retaining plate can extend to cut-off knife blade 31 below, can cover blade (as shown in Figure 4) fully, protect tighter.Elongated hole 531 on the gripper shoe 53 also tilts, the lower end of elongated hole 531 is than the more close cut-off knife 30 in upper end, like this when cut-off knife closure (rotating), because of wearing the relative slip between portion 54 and the elongated hole 531, make cutter retaining plate 51,52 can make progress, slide laterally simultaneously, so that can expose blade 31.
As shown in Figure 2, fix a profile of tooth support 11 on the base 10, the end face of profile of tooth support 11 is provided with a fan-shaped toothed region 111, also is provided with an axis hole 112 on the profile of tooth support 11, and axostylus axostyle 12 just is located in this axis hole 112.Be fixed with a slotted vane 34 on the cut-off knife 30, this slotted vane 34 is provided with a teeth groove dull and stereotyped 341 and is meshed with the toothed region 111 of described profile of tooth support, when cut-off knife 30 rotates with respect to axostylus axostyle 12, because the engaged transmission of teeth groove dull and stereotyped 341 and toothed region 111 will promote cut-off knife 30 with respect to sliding before and after the axostylus axostyle.Though; this is a kind of structure that can realize cut-off knife 30 and axostylus axostyle 12 relative slips; but the utility model is not limited to this a kind of concrete mode, so long as between cut-off knife 30 and the axostylus axostyle 12 relative slip can take place in the process of cutting, just can use protective device of the present utility model.
The outside that promotes bar 42 also is provided with an elastic pressuring plate 13, elastic pressuring plate 13 also is enclosed within on the axostylus axostyle 12, and by lock member 14 lockings, and then this cut-off knife 30 is produced the thrust of a normality, when this cut-off knife 30 presses down, this normality thrust can make cut-off knife 30 closely contact with fixed blade 20, guarantees to cut quality.
