Description

Technical Field

[0001] This utility model relates to the field of boot opening cutting clamp technology, specifically a cutting base. Background Technology

[0002] Modern boots come in a wide variety of styles, including Dr. Martens, Chelsea boots, snow boots, and work boots, suitable for different occasions and seasons. They are typically made of leather, rubber, or synthetic materials, and feature a high-top design for better support and warmth.

[0003] When producing high-top boots, some boot products require a slanted opening. If workers hold the boots by hand and use a horizontal rotary cutter to cut the boot opening, the workers cannot ensure that the slant angle of the boots is consistent every time, nor can they ensure that the cutting process is stable, which leads to a significant increase in the defect rate of the boots. Utility Model Content

[0004] The purpose of this invention is to provide a cutting base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutting base, comprising:

[0007] The base has a sloping surface at its front end and a mounting part at its rear end. A threaded rod is fixedly connected to the mounting part. A protective shell is provided on the outside of the mounting part and the threaded rod to protect the connection part. The threaded rod is threadedly fixed by a threaded knob on the mounting part. The bottom of the threaded knob is rotatably connected to the top of the mounting part. The center of the threaded knob has an opening that extends to the top of the mounting part.

[0008] An ankle clamp is fixedly connected to the top of a threaded rod. The inner side of the ankle clamp has a smooth inner edge. Rotary teeth are rotatably connected inside the ankle clamp and are distributed along the inner edge of the clamp. A chain is sleeved on the outer side of the rotating teeth, and Velcro is provided on the outer ends of the chain for securing the boot with the chain.

[0009] Preferably, the chain links are provided with fixing rings, which cooperate with fixing hooks to secure the ankle of the boot.

[0010] Preferably, the fixing ring has an abutment block facing the boot side for contacting the boot surface.

[0011] Preferably, the lower end face of the abutment block has a through hole for use with the fixing ring to limit the fixing hook.

[0012] Preferably, the mounting part has a slot on its side and the protective shell has a buckle on its side, and the slot and buckle cooperate to fix the protective shell.

[0013] Preferably, the top of the protective shell is provided with a relief groove for accommodating the threaded rod.

[0014] Preferably, the inner side of the Velcro is provided with a fixing surface.

[0015] Preferably, the fixing hook is rotatably connected to the Velcro.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses an inclined surface at the front end of the base to tilt the boot when it is placed on the base, thus tilting the horizontal boot opening downwards. With the ankle clamp securing the ankle of the boot, the horizontal rotary cutter can smoothly cut the boot opening, making it easier to create an inclined boot opening.

[0018] This invention involves installing a chain inside an ankle clamp, with the inner edge of the clamp conforming to the shape of the ankle part of the boot. After inserting the ankle clamp, the fixing hooks on both sides of the Velcro are used to hook the fixing ring of the chain, thereby limiting the chain and firmly fixing the ankle part of the boot with the chain. This prevents instability during cutting, which could lead to uneven cuts and an increased defect rate.

[0019] This invention features a threaded knob in the mounting section. When the threaded rod is inserted into the mounting section, turning the knob causes the internal thread of the knob to engage with the thread at the bottom of the threaded rod, thereby quickly fixing the threaded rod and thus quickly securing the ankle clamp. It is also easy to disassemble and replace the ankle clamp quickly to fit different boot sizes. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figures 1 to 7 This utility model provides a technical solution:

[0031] A cutting base, comprising:

[0032] The base 1 has a bevel 2 at its front end and a mounting part 3 at its rear end. A threaded rod 4 is fixedly connected to the mounting part 3. A protective shell 301 is provided on the outside of the mounting part 3 and the threaded rod 4 to protect the connection part. The threaded rod 4 is threadedly fixed by a threaded knob 305 on the mounting part 3. The bottom of the threaded knob 305 is rotatably connected to the top of the mounting part 3. The center of the threaded knob 305 has an opening that extends through to the top of the mounting part 3.

[0033] Ankle clamp 5 is fixedly connected to the top of threaded rod 4. The inner side of the ankle clamp 5 has a smooth inner edge 502. Rotary teeth 501 are rotatably connected inside the ankle clamp 5. The rotary teeth 501 are distributed along the inner edge 502 of the clamp. A chain 7 is sleeved on the outer side of the rotary teeth 501. Velcro 6 is provided on the outer sides of both ends of the chain 7 for cooperating with the chain 7 to fix the boot 9.

[0034] In this embodiment, the ankle clamp 5 is fixedly connected to the base 1 via a threaded rod 4. The front end of the base 1 has a slope 2. When the boot 9 is placed on the base 1, the bottom of the boot 9 contacts the slope 2, causing the boot 9 to tilt. Simultaneously, the ankle area above the boot 9 has a certain elasticity, allowing it to be inserted into the ankle clamp 5, thus securing the boot 9. The flat top of the boot 9 is fixed and tilted. Then, a horizontal rotary cutter 8 is used to horizontally cut the tilted top of the boot, cutting off the lower cut portion 901, thereby forming an upwardly tilted top (e.g., ...). Figure 7 ).

[0035] In this embodiment, the ankle clamp 5 has multiple rotating teeth 501 inside, which are distributed along the edge of the inner side 502 of the clamp. The shape of the inner side 502 of the clamp is consistent with the shape of the ankle part of the boot 9. A chain 7 (such as...) is sleeved between the outer sides of the rotating teeth 501. Figure 5 The chain 7 located outside the rotating tooth 501 is fixed by the inner wall of the ankle clamp 5 and the rotating tooth 501 to prevent disengagement. The chain 7 located inside the rotating tooth 501 is relatively loose, leaving a buffer space. When it is necessary to fix the boot 9, the ankle part of the boot 9 is inserted from the front opening of the ankle clamp 5. The abutment block 701 on the side of the chain 7 will contact the surface of the boot 9. The surface of the abutment block 701 is relatively rough and soft, so it will not damage the surface of the boot 9. At the same time, when the boot 9 moves into the clamp, it drives the chains 7 on both sides located in the ankle clamp 5 to contract inward, so that the inner chain 7 is squeezed inward, thereby making the chain 7 match the shape of the inner edge 502 of the clamp, thereby clamping the ankle part of the boot 9.

[0036] At this point, the chain 7 is compressed, and the loose chain 7 becomes tight. The chain 7 will tend to move to both sides to recover. To squeeze out the boot 9, use the Velcro 6. Align the fixed surface 602 with the higher coefficient of friction of the Velcro 6 with the ankle of the boot 9. Use the fixed hooks 601 on both sides of the Velcro 6 to hook the fixed rings 703 on the chain links. The lower end of the contact block 701 of the chain 7 has a through hole 702. While the fixed hook 601 hooks the fixed ring 703, the fixed ring 703 limits the top of the fixed hook 601 to prevent it from coming off. The fixed hooks 601 on both sides hook the chain 7 at both ends, so that the chain 7 moving to both sides is hooked and cannot move. In this way, the Velcro 6 firmly fixes the ankle of the boot 9, preventing the boot 9 from being unstable during cutting, which would cause the cut of the boot 9 to be uneven and increase the defect rate.

[0037] Specifically, a fixing ring 703 is provided on the link of the chain 7. The fixing ring 703 cooperates with the fixing hook 601 to fix the ankle of the boot 9.

[0038] Specifically, the inner side of the Velcro 6 is provided with a fixing surface 602.

[0039] Specifically, the fixing hook 601 is rotatably connected to the Velcro 6.

[0040] Specifically, the fixing ring 703 is provided with an abutment block 701 facing the side of the boot 9 for contacting the boot surface.

[0041] Specifically, the lower end face of the abutment block 701 is provided with a through hole 702, which is used to cooperate with the fixing ring 703 to limit the fixing hook 601.

[0042] In this embodiment, the rear end of the base 1 is provided with a mounting part 3. The mounting part 3 can cooperate with the protective shell 301 to protect the connection structure. The side of the protective shell 301 has a buckle 302, which cooperates with the slot 304 on the side of the mounting part 3 to quickly complete the fixation. When disassembling, it can be pulled outward by force.

[0043] In this embodiment, a threaded knob 305 is rotatably provided on the mounting part 3. The threaded knob 305 has a threaded opening at its center. When the threaded rod 4 is inserted into the mounting part 3, the threaded knob 305 is turned. The internal thread of the threaded knob 305 engages with the thread at the bottom of the threaded rod 4, thereby quickly fixing the threaded rod 4 and thus quickly fixing the ankle clamp 5. It is also convenient to disassemble and quickly replace the ankle clamp 5 to adapt to different boot sizes 9.

[0044] Specifically, the mounting part 3 has a slot 304 on its side, and the protective shell 301 has a buckle 302 on its side. The slot 304 and the buckle 302 cooperate to fix the protective shell 301.

[0045] Specifically, the top of the protective shell 301 is provided with a relief groove 303 for accommodating the threaded rod 4.

[0046] In use, the ankle clamp 5 is fixedly connected to the base 1 via a threaded rod 4. The front end of the base 1 has a slope 2. When the boot 9 is placed on the base 1, the bottom of the boot 9 contacts the slope 2, causing the boot 9 to tilt. The ankle clamp 5 has multiple rotating teeth 501 inside, distributed along the edge of the inner edge 502 of the clamp. The shape of the inner edge 502 matches the shape of the ankle part of the boot 9. A chain 7 is fitted between the outer sides of the rotating teeth 501. The portion of chain 7 located outside the rotating tooth 501 is fixed to the inner wall of the ankle clamp 5 and the rotating tooth 501 to prevent disengagement. The portion of chain 7 located inside the rotating tooth 501 is relatively loose, leaving buffer space. When it is necessary to secure the boot 9, it is inserted into the ankle area of ​​the boot 9 through the front opening of the ankle clamp 5. The abutment block 701 on the side of chain 7 will contact the surface of the boot 9. The surface of the abutment block 701 is relatively rough and soft, which will not damage the surface of the boot 9 while the boot 9 moves towards the clamp. When moving inward, the chains 7 located inside the ankle clamps 5 on both sides contract inward, causing the inner chains 7 to be squeezed inward, thus making the chain 7 conform to the shape of the inner edge 502 of the clamp, thereby clamping the ankle of the boot 9. At this time, the chain 7 is squeezed, the loose chain 7 becomes tight, and the chain 7 will tend to move to the sides to return to its original position. To squeeze out the boot 9, use the Velcro 6, aligning the fixing surface 602 with the higher coefficient of friction of the Velcro 6 with the ankle of the boot 9, and use the Velcro 6... The fixed hooks 601, which are rotatably arranged on both sides, hook onto the fixed rings 703 on the chain links of the chain 7. The lower end of the abutment block 701 of the chain 7 has a through hole 702. While the fixed hooks 601 hook onto the fixed rings 703, the fixed rings 703 limit the top of the fixed hooks 601 to prevent them from coming off. The fixed hooks 601 on both sides hook onto the chains 7 at both ends, so that the chains 7 moving to both sides are hooked and cannot move. In this way, the Velcro 6 can firmly fix the ankle of the boot 9.
