磨刀座Sharpening seat

本創作係有關於一種磨刀座。This creation is about a sharpening seat.

按，一般刀具在使用一端時間之後，會因為磨耗而使原本鋒利的刀鋒產生鈍化。當刀鋒鈍化之後，若要將刀具之刀鋒磨利，一般採用塊狀磨刀石來進行，然磨刀石笨重、操作不易、收納不便。Press, after the general tool is used for one end time, the original sharp blade will be passivated due to wear. When the blade is passivated, if the blade of the tool is to be sharpened, it is generally carried out by using a block-shaped sharpening stone, but the sharpening stone is heavy, the operation is not easy, and the storage is inconvenient.

緣此，市面上即有較輕巧的磨刀座因應而生，如TWM519568、TWM409921所揭示者即為此類。雖然磨刀座使用尺寸極小之磨刀片即可達到研磨刀鋒之功效，例如TWM519568之習知結構是將磨刀片先安置於一底座，再將該磨刀片鎖固於該蓋體，藉由該蓋體與該底座壓抵固定該磨刀片，而TWM409921之習知結構是透過將蓋體鎖固於底座上，以將磨刀片壓掣於蓋體與底座之間。然而，此類習知結構在安裝或拆換上皆需要另外進行鎖緊或旋鬆動作才得以完成，無論是在結構、製造、組裝上較為複雜，拆卸、移除或更換也較不易且耗時。For this reason, there is a lighter sharpening seat on the market, as disclosed by TWM519568 and TWM409921. Although the sharpening seat can achieve the effect of grinding the blade with a very small size grinding blade, for example, the conventional structure of TWM519568 is to first place the grinding blade on a base, and then lock the grinding blade to the cover body, by the cover The body is pressed against the base to fix the grinding blade, and the conventional structure of TWM409921 is to lock the grinding blade between the cover body and the base by locking the cover body to the base. However, such conventional structures require additional locking or unscrewing operations to be completed during installation or replacement, which is complicated in structure, manufacture, and assembly, and is not easy to disassemble, remove, or replace. Time.

因此，有必要提供一種新穎且具有進步性之磨刀座，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive sharpening seat to solve the above problems.

本創作之主要目的在於提供一種磨刀座，可改變安裝磨刀件之夾掣空間，藉此可直接安裝、 移除或更換該磨刀件，結構、製造、組裝簡單，且該磨刀件之拆卸、移除或更換簡易、快速。The main purpose of the present invention is to provide a sharpening seat which can change the clamping space for installing the sharpening member, thereby directly installing, removing or replacing the sharpening member, which is simple in structure, manufacture and assembly, and the sharpening member It is easy and quick to remove, remove or replace.

The first clamping wall 11 is further provided with two slots 113. The carrier 23 includes two laterally displaced slots 231 and positioning protrusions 232 adjacent to the two slots 231. The two slots 231 correspond to The two accommodating spaces 31 are preferably extended from the opposite sides, and one of the positioning protrusions 232 is located at the stepped recess of the two accommodating spaces 31, thereby effectively positioning and supporting The two-grinding blade 41. Of course, the carrier 23 can be provided with no seating groove, and the sharpening member 40 can be directly clamped and fixed between the first and second clamping walls 11, 21. When the sharpening member 40 is fixedly positioned in the clamping space 30, the two positioning projections 232 are engaged with the two positioning grooves 113 to stabilize the carrier 23 without shaking left and right. The carrier 23 is further provided with a slope 233 which is obliquely inclined obliquely toward the second clamping wall 21 and abuts against a lower end surface of the first clamping wall 11 to guide the carrier 23 and The first clamping wall 11 smoothly joins and further fixes the carrier 23 and the two-grinding blade 41.

在本實施例中，該基座10另設有一吸盤50，該基座10並於相對該吸盤50之一周面處開設一缺口14，便於由外界扳動該吸盤50而解除真空吸附狀態。較佳地，該基座10另設有一扳動件60，該扳動件60樞接於一連桿70之一端，該連桿70另一端連接該吸盤50，藉由扳動該扳動件60可使該吸盤50吸附於一物件之表面。In this embodiment, the susceptor 10 is further provided with a suction cup 50. The pedestal 10 defines a notch 14 at a peripheral surface of the suction cup 50 to facilitate the vacuum suction state by pulling the suction cup 50 from the outside. Preferably, the base 10 is further provided with a triggering member 60. The triggering member 60 is pivotally connected to one end of a connecting rod 70. The other end of the connecting rod 70 is connected to the suction cup 50 by pulling the triggering member. 60 allows the suction cup 50 to be attracted to the surface of an object.

綜上，透過該活動件可活動地設於該基座而可改變該第一與第二夾掣壁之間的夾掣空間，藉此可直接安裝、 移除或更換該磨刀件，結構、製造、組裝簡單，且該磨刀件之拆卸、移除或更換簡易、快速。In summary, the movable member is movably disposed on the base to change the clamping space between the first and second clamping walls, thereby directly mounting, removing or replacing the sharpening member.
