In some examples, the cutting aid 1 according to the present invention may include a main body portion 11, a positioning portion 111 provided to the main body portion 11 and used for positioning the to-be-cut piece 2, and a defining portion 112 provided to the main body portion 11 and used for defining the cutting blade 13 (see fig. 1 to 7).

In some examples, the piece 2 to be cut may be any material suitable for being segmented by cutting, such as a strip of glue (tube), a strip of plastic (tube), a strip of metal (tube), a strip of wood (tube), a strip of cardboard (tube), a strip of glass (tube), etc.

In some examples, the body portion 11 may be made of a transparent or translucent material. For example, the main body 11 may be made of transparent glass, translucent glass, transparent plastic, or translucent plastic. In this case, the operator can observe the position of the work piece 2 when cutting the work piece 2, thereby being able to improve the accuracy with which the work piece 2 is cut.

The positioning portion 111 and the defining portion 112 are described below.

In some examples, as described above, the cutting assist tool 1 may include the positioning portion 111 (see fig. 1, 5, and 7). The positioning part 111 can position the member to be cut 2.

In some examples, the positioning portion 111 may be a channel having a predetermined length formed by being inwardly recessed from the first surface 11a of the main body portion 11 along the first direction D1 (see fig. 1). The predetermined length is greater than the distance from the first surface 11a to the defining portion 112. In other words, the positioning part 111 may be located inside the main body part 11, the positioning part 111 may be a channel having a predetermined length, and one end of the positioning part 111 may extend to the first surface 11a of the main body part 11 and communicate with the outside.

According to the present disclosure, the shape of the positioning part 111 formed inside the main body part 11 and the shape of the work piece 2 are matched with each other. After the piece to be cut 2 is inserted into the positioning part 111, the wall of the positioning part 111 can position the piece to be cut 2, so that the piece to be cut 2 is ensured to be stable in the cutting process, and the cutting precision of the piece to be cut 2 can be improved.

In some examples, when the member to be cut 2 is elongated, the positioning portion 111 may also be elongated (see fig. 1 and 7).

In some examples, the locating portion 111 may have a circular cross-section, the diameter of which may be slightly larger than the diameter of the piece 2 to be cut. In some examples, the diameter of the locating portion 111 may be 0.5mm-1mm larger than the diameter of the piece 2 to be cut. For example, the diameter of the locating portion 111 may be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm larger than the diameter of the piece 2 to be cut.

In some examples, the diameter of the positioning portion 111 may be in the range of 8mm-80 mm. For example, the diameter of the positioning part 111 may be 8mm, 9mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, or 80 mm.

In some examples, the diameters of the positioning portions 111 at different longitudinal positions may be substantially equal. In other examples, the diameters of the positioning portions 111 at different longitudinal positions may be gradually enlarged or gradually reduced in the first direction D1.

In some examples, the positioning portion 111 may have a first portion 111a close to the first surface 11a and a second portion 111b far from the first surface 11a and hollowed out (see fig. 1 and 7). The first portion 111a and the second portion 111b of the positioning portion 111 are cut off by the defining portion 112 (see fig. 1 and 7). In some examples, the upper side of the second portion 111b is hollowed out (see fig. 1, 2, 6, and 7). The length of each segment formed by cutting the piece to be cut 2 by the cutting aid 1 is defined by the extension length (depth) of the second portion 111 b.

In some examples, the length of the first portion 111a may be smaller than the length of the second portion 111b, i.e., the position where the defining part 112 intercepts the positioning part 111 may be located at one end of the positioning part 111 close to the first surface 11 a. In other examples, the length of the first portion 111a may be equal to the length of the second portion 111b, i.e., the position where the defining part 112 intercepts the positioning part 111 may be located at the middle of the positioning part 111. In still other examples, the length of the first portion 111a may be greater than the length of the second portion 111b, i.e., the position where the defining portion 112 intercepts the positioning portion 111 may be located at an end of the positioning portion 111 away from the first surface 11 a. It will be appreciated that the length of the first portion 111a may determine the cutting accuracy of the cutting aid 1. The longer first portion 111a allows the work piece 2 to have a longer locating surface, and the work piece 2 can be more stably maintained at its original position during cutting of the work piece 2. The cut end face of the part formed by the piece 2 to be cut thus has a small surface roughness. Conversely, for the example using a shorter first portion 111a, the cut end face of the part has a greater surface roughness.

In some examples, as described above, the cutting aid 1 may include a defining portion 112 (see fig. 1-3 and 6-7). The defining portion 112 can define the cutting blade 13 and facilitate an operator applying force to the cutting blade 13.

In some examples, the positioners 111 may extend along a first direction D1, and the defining part 112 may extend along a second direction D2 intersecting the first direction D1 and traverse inside the positioners 111 (see fig. 1, 2 and 7). That is, the to-be-cut piece 2 may be transversely cut by the cutting blade 13 in the second direction D2.

In some examples, the defining portion 112 may be a groove 112 (see fig. 1-3 and 6-7) having a predetermined depth and a predetermined width and extending along the second direction D2 formed on the main body portion 11. Thereby, the cutting blade 13 can be defined and the operator can be facilitated to apply force to the cutting blade 13.

In some examples, the defining portion 112 may be formed by a surface of the main body portion 11 being inwardly recessed (see fig. 1 to 3 and 7). In this case, the height of the notch of the defining portion 112 coincides with the height of the surface of the main body portion 11.

In other examples, the surface of the main body 11 may be convexly formed with protrusions, and the defining part 112 may be formed by the surfaces of the protrusions being inwardly recessed.

In some examples, the width of the defining portion 112 may be slightly greater than the thickness of the cutting blade 13, for example, the width of the defining portion 112 is 0.2mm-1mm greater than the thickness of the cutting blade 13. The width of the defining portion 112 may be set to 1mm to 15mm, for example, 2mm, 3mm, or the like.

In some examples, the depth of the defining portion 112 may be 30mm-120 mm. For example, the depth of the defining portion 112 may be 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, or 120 mm. This is set according to the size of the piece 2 to be cut.

It is understood that the cutting blade 13 may move in the defining portion 112 along the extending direction of the defining portion 112 (i.e., the second direction D2) and also may move toward the bottom surface of the defining portion 112 along the depth direction of the defining portion 112. Therefore, when the length of the defining portion 112 is smaller than, equal to, or larger than the length of the cutting blade 13, the defining portion 112 can both define the cutting blade 13 and facilitate the operator to apply force to the cutting blade 13. Therefore, in the present invention, the length of the limiting portion 112 is not limited.

In some examples, the number of the positioning portions 111 may be plural. The plurality of positioners 111 may extend along the first direction D1 and be disposed at intervals along the second direction D2, and the defining part 112 may extend along the second direction D2 intersecting the first direction D1 and sequentially cross the plurality of positioners 111. In this case, the cutting blade 13 can cut a plurality of work pieces 2 at a time, whereby the efficiency of the work pieces 2 to be cut can be improved.

In some examples, the number of the defining portions 112 may be plural. The plurality of defining parts 112 may extend in the second direction D2 intersecting the first direction D1 and traverse the positioning parts 111 extending in the first direction D1, and the plurality of defining parts 112 may be disposed at intervals in the first direction D1. In this case, both ends of the member to be cut 2 can be cut respectively by the plurality of defining portions 112 at different pitches, thereby cutting a plurality of desired parts at the same time.

In some examples, a central plane of the defining part 112 along the depth direction and an axis of the positioning part 111 may be orthogonal (see fig. 1 and 7), that is, an included angle between the central plane of the defining part 112 along the depth direction and the axis of the positioning part 111 may be a right angle. In this case, the end face of the piece 2 to be cut is perpendicular to its axis.

In other examples, the angle between the central plane of the defining portion 112 in the depth direction and the axis of the positioning portion 111 may be an acute (obtuse) angle. For example, the angle of the central plane of the defining portion 112 in the depth direction with the axis of the positioning portion 111 may be 10 °, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 70 °, or 80 °.

In some examples, referring to fig. 1 and 2, the second portion 111b is preferably formed to have an open groove form so as to facilitate the outside to see whether the member to be cut 2 touches the bottom of the second portion 111 b.

In some examples, the cutting aid 1 may further include a case 12 detachably fitted over the main body portion 11.

In some examples, the main body portion 11 is formed with a through hole 11b capable of communicating the second portion 111b and the case 12 at a position corresponding to the second portion 111b (see fig. 4). In this case, the cut pieces may automatically fall into the case 12 through the through-holes 11b by gravity, whereby the collection efficiency of the cut pieces can be improved.

In some examples, the case 12 may be a metal case, a glass case, a wood case, a paper case, a rubber case, a plastic case, or the like. Further, the case 12 may be made of a transparent or translucent material, in which case the operator can observe in time whether the case 12 is full of cut pieces and transfer in time.

In some examples, a boss 113 may be provided on a lower surface of the body portion 11. The case 12 may be located below the main body 11 and sleeved outside the boss 113. In some examples, the case 12 and the boss 113 may be sleeved, clamped, screwed, or the like.

In some examples, the cutting aid 1 may further include a positioning block 14 movably secured to the body portion 11 (see fig. 7). The positioning block 14 may be formed with a protrusion 141 protruding from a lower surface thereof (see fig. 7).

In some examples, the shape of the protrusion 141 and the shape of the second portion 111b may match (see fig. 7). The protrusion 141 may protrude into the second portion 111b to block further protrusion of the to-be-cut member 2 inserted into the second portion 111 b. In this case, when the workpiece 2 is inserted into the second portion 111b and abuts against the positioning block 14, the positioning block 14 can limit further insertion of the workpiece 2 inserted into the second portion 111b, whereby the length of the cutting tool can be adjusted. According to the length of the desired cut, the worker can slide the positioning block 14 in the second portion 111b to the desired position in real time, and then perform the cutting operation.

Additionally, in some examples, the cutting assist tool 1 may further include a cutting blade 13 (see fig. 1-7).

In some examples, the cutting blade 13 may be hinged to one end of the defining portion 112, and the cutting blade 13 may be rotatable toward the bottom surface of the defining portion 112 with the one end as a fixed point (not shown). It will be appreciated that the plane of rotation of the cutting blade 13 should now be in the same plane as the central plane of the defining portion 112. In this case, the operator can cut the member to be cut 2 by simply taking the cutting blade 13 and rotating the cutting blade 13 in a direction close to the bottom surface of the defining portion 112, whereby the convenience of the cutting blade 13 for cutting the member to be cut 2 can be improved.

In some examples, cutting blade 13 may be hinged to the bottom surface of defining portion 112. In other examples, cutting blade 13 may be hinged to the side of defining portion 112.

In some examples, the length of the cutting blade 13 may be greater than the length of the defining portion 112. In this case, the operator can take the cutting blade 13 more conveniently, and thus, the convenience of using the cutting blade 13 can be improved.

In addition, in some examples, a protective pad (not shown) may be laid on the bottom surface of the defining portion 112. It is understood that when the cutting blade 13 cuts the member to be cut 2, the cutting blade 13 may damage the bottom surface of the defining portion 112 to some extent, and the damage of the bottom surface of the defining portion 112 may affect the cutting effect. In this case, the bottom surface of the defining portion 112 can be protected by providing the protection pad, whereby the service life of the cutting aid 1 can be extended.

In some examples, the length of the protection pad is preferably set to be greater than or equal to the length of the bottom surface of the restriction portion 112, and one end thereof is protruded beyond the restriction portion 112 during the laying process. The protection pad may be spread over the bottom surface of the defining part 112. This allows the protection pad to protect the entire bottom surface of the defining portion 112. In case of a serious damage of the protection pad, the worker can pull out the protection pad by pulling the exposed end of the protection pad in a portable manner, which can improve the replacement speed of the protection pad.

In some examples, the protective pad may be made of a rubber material, a sponge material, a fiber material, a plastic material, and the like. In other words, the protection pad may be a rubber product, a sponge product, a fiber product, a plastic product, or a plastic product.

In some examples, the defining part 112 may be formed by a surface of the main body part 11 being depressed inward, and a protection pad may be laid on a bottom surface of the defining part 112, and may protrude from the surface of the main body part 11. Because the protection pad belongs to the consumable article, the protection pad is outstanding on the surface of main part 11 for the operator is more easily to carry out old and new change to the protection pad, can improve the convenience that the protection pad was changed from this.

According to the present invention, it is possible to provide a cutting assistance tool 1 that is capable of positioning a work piece 2 to be cut, defining a cutting blade 13, and facilitating an operator to apply a force to the cutting blade, whereby the accuracy with which the work piece 2 is cut can be improved.

While the utility model has been specifically described above in connection with the drawings and examples, it will be understood that the above description is not intended to limit the utility model in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the true spirit and scope of the utility model, and such modifications and variations are within the scope of the utility model.
