Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting tool technology, and specifically relates to a cutting head structure. Background Technology
[0002] Chinese utility model publication number CN202192629U discloses an ultra-thin double-locking blade holder for cutting knives, including a blade head, a cover plate, and a blade inserted into a cavity formed by the blade head and the cover plate. The blade has two positioning notches, and the blade head has a notch at its upper part. A locking positioning shell is installed on the blade head, and the locking positioning shell has two locking pins located in the notch position. It can be seen that the prior art requires numerous components for the installation and positioning of the blade and the blade head, resulting in inconvenient disassembly and installation of the knife and high product manufacturing costs. Utility Model Content
[0003] This solves the problem of inconvenient blade removal and installation in existing cutter heads.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a blade head structure, comprising a blade head body, the blade head body comprising a top mounting portion, a tail mounting portion, a bottom mounting portion and a front opening, the tail mounting portion having a top mounting portion at the top and a bottom mounting portion at the bottom to form a blade mounting space, the tail mounting portion having a front opening at the front end, and mounting grooves provided in the top mounting portion, tail mounting portion and bottom mounting portion.
[0005] Furthermore, the top mounting portion includes a positioning portion, which has a protruding positioning block that engages with the blade.
[0006] Furthermore, the end of the positioning part is connected to the top mounting part, and there is a gap between the other parts of the positioning part and the cutter head body.
[0007] The present invention has the following advantages: the blade body is positioned and installed with the blade through the mounting grooves at the top, bottom and tail ends, which makes the installation structure between the blade and the blade body simpler. The blade is connected to the positioning block by a snap-fit, which makes the disassembly and fixing of the blade and the blade body simpler and more convenient, saving labor and material costs. Attached Figure Description
[0008] Figure 1 This is a perspective view of the present utility model; Figure 2 This is the front view of the present invention; Reference numerals: cutter head body 10; top mounting part 11; tail mounting part 12; bottom mounting part 13; front opening 14; mounting groove 15; positioning part 20; positioning block 21; gap 22. Detailed Implementation
[0009] like Figures 1 to 2 As shown, a blade head structure includes a blade head body 10. The blade head body 10 includes a top mounting portion 11, a tail mounting portion 12, a bottom mounting portion 13, and a front opening 14. The tail mounting portion 12 has a top mounting portion 11 at its top and a bottom mounting portion 13 at its bottom, thus forming a blade mounting space. The tail mounting portion 12 has a front opening 14 at its front end. The top mounting portion 11, tail mounting portion 12, and bottom mounting portion 13 are all provided with mounting grooves 15. In use, the top of the blade is located in the top mounting portion 11, the tail is located in the tail mounting portion 12, and the bottom is located in the bottom mounting portion 13. The front part of the blade extends to the outside of the blade head body 10 through the front opening 14, thereby enabling it to cut objects.
[0010] The top mounting part 11 includes a positioning part 20, which has a protruding positioning block 21 that engages with the blade. In order to prevent the blade from moving arbitrarily in the cutter head body 10 and affecting the normal use of the cutter, the top of the blade is provided with a slot. When the blade is installed in the cutter head body, the positioning block 21 at the top of the cutter head body 10 is located in the slot of the blade, so that the blade is fixedly installed in the cutter head body.
[0011] To facilitate the installation and removal of the blade from the cutter head body, the end of the positioning part 20 is connected to the top mounting part 11. A gap 22 is provided between the other parts of the positioning part 20 and the cutter head body 10. When the blade needs to be removed from the cutter head body, the positioning part 20 is pulled outward to make the positioning block 21 leave the blade's slot, thus completing the blade removal operation. When the blade needs to be installed into the cutter head body, after the blade's slot moves to the position of the corresponding positioning block 21, the positioning part 20 automatically resets itself through its own elasticity, causing the positioning block 21 to fall into the blade's slot to complete the fixed installation.
[0012] In summary, the blade head structure of this utility model has a blade body 10 that is positioned and installed with the blade through the mounting grooves 15 at the top, bottom and tail ends, which simplifies the installation structure between the blade and the blade head body. The blade is engaged with the positioning block 21, which makes the disassembly and fixing of the blade and the blade head body simpler and more convenient, saving labor and material costs.
