[0029] The present embodiment provides a cutter to solve the technical problem that the cutter cannot effectively ensure the perpendicularity of the cutting surface and the surface of the honeycomb material in the prior art.

[0030] As shown in Figs. 1-2 The cutter 1 provided by the present embodiment includes a blade 11, a handle 12, and a limiting assembly 13. The blade 11 is used to cut the workpiece, the limiting assembly 13 is provided with a relief groove 1311, and the handle 12 is installed at one end of the groove wall of the relief groove 1311. The handle 12 has an installation inner cavity, and the blade 11 is slidingly installed on the cavity wall of the installation inner cavity, that is, part of the blade 11 can protrude from the installation inner cavity of the handle 12, so that one end of the blade 11 can pass through the relief groove 1311 to cut the workpiece. The lower end of the limiting assembly 13 has a positioning plane, and the positioning plane can be attached to the surface of the workpiece.

[0031] Understandably, if the blade 11 is directly operated to cut the workpiece, the perpendicularity between the blade 11 and the surface of the workpiece cannot be accurately controlled, which inevitably causes the cutting surface to be uneven, and when the cut workpiece is spliced, a large splicing gap or skew phenomenon occurs, which greatly affects the quality of the spliced product. In the present embodiment, by providing the limiting assembly 13, the positioning plane at the lower end of the limiting assembly 13 can be attached to the surface of the workpiece, so that after the blade 11 protrudes from the installation inner cavity of the handle 12 and passes through the relief groove 1311, the blade 11 can be perpendicular to the surface of the workpiece, thereby vertically cutting the workpiece, so that the cutting surface is uniform and has good perpendicularity, and the side surface of the cut workpiece will not have a large splicing gap or skew phenomenon when splicing, thereby greatly improving the splicing effect.

[0032] The workpiece is generally a honeycomb material, but the workpiece can also be other workpieces that have high requirements for cutting perpendicularity. This is not the focus of the present embodiment and is not limited here.

[0033] In order to reduce the weight of the limiting assembly 13 and increase the area of the positioning plane, the limiting assembly 13 comprises a limiting plate 131, which forms the positioning plane on the lower end surface in the thickness direction of the limiting plate 131. This arrangement can effectively reduce the weight of the limiting assembly 13 and increase the area of the positioning plane as much as possible, thereby greatly improving the cutting perpendicularity of the cutter 1.

[0034] Optionally, the limiting plate 131 comprises two opposite and spaced limiting sub-plates 1313, and an avoiding groove 1311 is formed between the two limiting sub-plates 1313. The limiting assembly 13 further comprises a connecting piece connecting the limiting sub-plates 1313 on both sides of the avoiding groove 1311. This arrangement can reduce the weight of the limiting plate 131 and improve the portability of the limiting assembly 13. The connecting piece can connect the limiting sub-plates 1313 on both sides of the avoiding groove 1311 into one body, ensuring that the positioning plane is always flush with the surface of the workpiece, thereby ensuring the cutting perpendicularity and improving the use reliability of the cutter 1.

[0035] Optionally, the shank 12 is rotatably installed at one end of the groove wall of the avoiding groove 1311. This arrangement facilitates the control of the cutting angle of the blade 11, making it easier to cut into the workpiece and improving the functional rationality of the cutter 1.

[0036] In order to improve the portability of the cutter 1 and reduce the occupied space, the avoiding groove 1311 is at least through one side of the limiting assembly 13, so that at least part of the shank 12 can be rotated into the avoiding groove 1311.

[0037] Optionally, the limiting assembly 13 comprises a limiting plate 131 and a rotating shaft 132. The limiting plate 131 has a positioning plane and an avoiding groove 1311, the rotating shaft 132 passes through one end of the shank 12, and the rotating shaft 132 is installed at both ends of the groove wall of the avoiding groove 1311. The rotating shaft 132 is used to install the shank 12 on the groove wall of the avoiding groove 1311, which can improve the smoothness of the rotation of the shank 12 and the installation reliability of the shank 12, thereby improving the structural rationality of the overall cutter 1.

[0038] Optionally, the limiting plate 131 is provided with an installation hole 1312 through the limiting plate 131 in a direction perpendicular to the extension direction of the avoiding groove 1311, and the installation hole 1312 penetrates the groove wall of the avoiding groove 1311. The rotating shaft 132 is inserted into the installation hole 1312. This arrangement allows the blade 11 or the shank 12 to be removed by pulling out the rotating shaft 132 from the installation hole 1312 when maintenance or replacement is required, thereby improving the convenience of maintenance and improving the use reliability of the cutter 1.

[0039] To ensure that the cutting line on the surface of the workpiece conforms to the predetermined trajectory, thereby improving the cutting accuracy, the cutter 1 also comprises a guide piece, the length direction of the guide piece is parallel to the cutting direction, and one side of the limiting assembly 13 abuts against one side of the guide piece, so that the limiting assembly 13 can slide along the length direction of the guide piece. This arrangement enables the limiting assembly 13 to move along the length direction of the guide piece, and then enables the cutting line to move along the predetermined trajectory, so that the workpiece is less likely to have a large joint gap after cutting and splicing, thereby improving the splicing quality of the workpiece.

[0040] Illustratively, one side of the guide piece is provided with a sliding groove, and one side of the limiting assembly 13 is provided with a sliding part which is slidingly installed in the sliding groove. This arrangement makes the sliding of the limiting assembly 13 more smooth, and ensures that the limiting assembly 13 always abuts against the guide piece, so that the cutting line always conforms to the predetermined trajectory, thereby improving the cutting accuracy.

[0041] The sliding part is preferably a sliding block, so as to further improve the sliding smoothness. In other embodiments, it can also be provided in other forms of sliding parts, which are not limited here.

[0042] To facilitate marking the cutting start position and the cutting distance, the limiting assembly 13 is vertically and throughly provided with a marking hole towards the positioning plane. The staff can use a marker pen to mark the cutting start position from the marking hole, or draw the cutting trajectory during the cutting process to calculate the cutting distance, thereby expanding the functionality of the cutter 1.

[0043] To ensure that the blade 11 is locked after being pulled out of the installation inner cavity by a certain distance and to ensure that the blade 11 is fixed during cutting, illustratively, the handle 12 is provided with a through groove along one side of the length direction of the handle 12, the cavity wall away from the through groove is provided with a positioning groove along the length direction of the handle 12, the blade 11 is provided with a positioning hole, and the cutter 1 further comprises a positioning pin, one end of the positioning pin passes through the positioning hole and cooperates with the positioning groove, and the other end of the positioning pin extends out of the through groove. Understandably, after the positioning pin is pulled to make the blade 11 extend by a required length, the positioning pin is pressed, and the positioning pin is inserted into the groove wall of the positioning groove, so as to fix the positioning hole on the blade 11 at the positioning groove, thereby completing the locking of the extension length of the blade 11. When the blade 11 is idle, the positioning pin can be slightly pulled outwards, so that the positioning pin is separated from the positioning groove, and then the positioning pin is pulled to retract the blade 11.

[0044] Optionally, the cavity wall of the installation inner cavity is provided with a gear, the blade 11 is provided with a rack along the length direction of the blade 11, the gear and the rack are engaged, one side surface of the handle 12 is provided with a through hole, and the cutter 1 further comprises a rocker, the rocker passes through the through hole and is in transmission connection with the gear. This arrangement can make the blade 11 more labor-saving in extension and retraction, and improve the flexibility and usability of the cutter 1.

[0045] The working process of the cutter 1 in this embodiment is as follows:

[0046] Firstly, the guide is placed on the workpiece surface according to the preset cutting track, then the limiting assembly 13 is abutted against the guide, the cutting direction is parallel to the length direction of the guide, then the blade 11 is extended out of the handle 12, the handle 12 is rotated to find a suitable and labor-saving cutting angle, then the blade is lowered, finally the handle 12 is held to slide along the length direction of the guide to cut the workpiece, and the marker pen can be used to mark the cutting starting position or draw the cutting track from the marking hole as required during the period.
