Examples
As shown in fig. 1-8, the material drawing knife capable of stably clamping according to this embodiment includes a knife handle 10, a fixing rod 21 fixedly connected to the knife handle 10, a first clamping plate 22 fixedly connected to the fixing rod 21, a second clamping plate 23 fixedly connected to the fixing rod 21, a first clamping piece 24 fixedly connected to a side of the first clamping plate 22 close to the second clamping plate 23, a second clamping piece 25 fixedly connected to a side of the second clamping plate 23 close to the first clamping plate 22, a positioning block disposed at an end of the fixing rod 21 far from the knife handle 10, a pressing rod 29 disposed between the first clamping plate 22 and the second clamping plate 23, and a knob 31; one end of the extrusion rod 29 is rotatably connected with the positioning block, and the other end of the extrusion rod penetrates through the cutter handle 10 and then is fixedly connected with the knob 31; the section enclosed by the first clamping plate 22 and the second clamping plate 23 is U-shaped; the first clamping piece 24 and the second clamping piece 25 are used for clamping the blade 40; the section of the pressing rod 29 provided between the first clamping plate 22 and the second clamping plate 23 is oval. Specifically, when the cutting tool is used, the knob 31 can be turned to rotate the extrusion rod 29, so that the extrusion rod 29 separates (the distance between) the first clamping plate 22 and the second clamping plate 23, and further the gap between the first clamping plate 24 and the second clamping plate 25 is larger, at this time, the cutting blade 40 is placed in the first clamping plate 24 and the second clamping plate 25, and the knob 31 is loosened (or turned) so that the extrusion rod 29 does not extrude the first clamping plate 22 and the second clamping plate 23, and further the first clamping plate 22 and the second clamping plate 23 can clamp the first clamping plate 24 and the second clamping plate 25, and further the cutting blade 40 therein is clamped. The same applies to the blade 40 when removed. Therefore, the blade 40 can be clamped in a larger area, the blade 40 is more stable to fix, the situation that the blade 40 is bent and the like in the using process can be effectively avoided, and the blade 40 is more convenient to disassemble, assemble and replace. It should be noted that the lengths of the tool holder 10, the fixing rod 21, the first clamping plate 22, the second clamping plate 23, the first clamping plate 24, the second clamping plate 25 and the extruding rod 29 are all parallel to each other, and the planes of the first clamping plate 24 and the second clamping plate 25 are parallel to each other after the blade 40 is clamped by the two clamping plates.
One side of the first clamping plate 22 close to the tool shank 10 in the embodiment is fixedly connected with the tool shank 10. Specifically, the pressing bar 29 is rotated so that only the second clamp plate 23 is pushed away, thereby enabling the blade 40 to be used more stably.
In this embodiment, a stopper 26 is disposed on a side of the first clip piece 24 close to the second clip piece 25, and a length direction of the stopper 26 is parallel to a length direction of the first clip piece 24; the thickness of the stop 26 is less than the thickness of the blade 40; the stop 26 is configured to abut against the back of the blade 40. In particular, this allows better fixing of the position of the blade 40, avoiding the blade 40 from sliding in the first and second jaws 24, 25 during use.
In the embodiment, a fixing plate 27 is arranged at one end of the first clamping piece 24 close to the knife handle 10, and a convex block 28 is arranged at one side of the fixing plate 27 close to the second clamping piece 25; the fixing plate 27 is located on the same plane as the first jaw 24. Specifically, the ends of the blade 40 will typically all begin to be used as the securing holes, and thus aligning the holes with the projections 28 allows for easier positioning of the blade 40 and improved stability of the securing of the blade 40.
The thickness of the bump 28 in this embodiment is less than the thickness of the blade 40. In particular, this allows for more convenient gripping of the blade 40 in the first and second jaws 24, 25.
The sections of the knife handle 10 and the knob 31 in the embodiment are both oval; one side of one end of the knob 31, which is close to the blade 40, is provided with an accommodating groove 32, a fixture block 33 is arranged in the accommodating groove 32 in a sliding manner, one side of the fixture block 33, which is close to the accommodating groove 32, is provided with a first groove 34, and a spring 36 is arranged in the first groove 34; one end of the spring 36 is fixedly connected with the inner wall of the first groove 34, and the other end is fixedly connected with the inside of the accommodating groove 32; the axial direction of the spring 36 is parallel to the length direction of the tool shank 10. Specifically, when the first clamping piece 24 and the second clamping piece 25 clamp the blade 40 for normal use, the cross section of the knob 31 completely coincides with the cross section of the handle 10, so that the extrusion rod 29 cannot rotate due to the fact that the knob 31 is touched during use, when the blade 40 needs to be replaced or installed, the clamping block 33 can be ejected out for a certain distance by the spring 36 only by twisting the knob 3190 degrees, and then the clamping block is clamped at the end portion of the handle 10 (as shown in fig. 1), and therefore the knob 31 does not need to be pressed all the time.
In the embodiment, the first groove 34 is internally provided with a second groove 35, the diameter of the second groove 35 is smaller than that of the first groove 34, and the second groove 35 and the first groove 34 are coaxially arranged; a sliding rod 37 is arranged in the second groove 35 in a sliding manner, the sliding rod 37 is arranged in the spring 36, and one end of the sliding rod 37 is fixedly connected with the inner wall of the accommodating groove 32. Specifically, this can make the movement of the latch 33 more stable.
The first clamping plate 22 and the second clamping plate 23 in this embodiment are made of stainless steel with toughness. In particular, this can be more durable and more convenient to disinfect.
The first clamping piece 24 and the second clamping piece 25 in this embodiment have frosted surfaces on the sides close to the blade 40. In particular, this enables the first and second jaws 24 and 25 to more stably hold the blade 40.
In summary, the material taking knife capable of stably clamping in this embodiment can rotate the extrusion rod 29 by twisting the knob 31 when in use, so that the extrusion rod 29 separates (the distance between) the first clamping plate 22 and the second clamping plate 23, and further the gap between the first clamping plate 24 and the second clamping plate 25 is larger, at this time, the blade 40 is placed in the first clamping plate 24 and the second clamping plate 25, and the knob 31 is loosened (or twisted) so that the extrusion rod 29 does not extrude the first clamping plate 22 and the second clamping plate 23 any more, and further the first clamping plate 22 and the second clamping plate 23 can clamp the first clamping plate 24 and the second clamping plate 25 tightly, and further clamp the blade 40 therein tightly. The same applies to the blade 40 when removed. Therefore, the blade 40 can be clamped in a larger area, the blade 40 is more stable to fix, the situation that the blade 40 is bent and the like in the using process can be effectively avoided, and the blade 40 is more convenient to disassemble, assemble and replace.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
