Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 11, the present embodiment provides a handle-adjustable knife including a knife body 100 and a handle 200. The cutter body 100 has a cutting edge 110 and a back 120. The cutter body 100 and the handle 200 are coupled by a locking coupling mechanism 300. The locking coupling mechanism 300 is disposed on the tool back 120 of the tool body 100 near one end of the tool body 100 and extends into the handle 200 to couple the tool body 100 and the handle 200. The handle 200 can rotate around the locking link 300 in a plane parallel to the blade back 120, and the locking link 300 can lock the handle 200 at two positions in the same plane as the blade body 100. When the cutter is used, the handle 200 is rotated according to the condition of the cut object, the handle 200 is adjusted to two positions of extending to the outside of the cutter body 100 (as shown in fig. 4) or extending to the other end direction of the cutter body 100 (as shown in fig. 3), and then the locking connection mechanism 300 is used for locking, so that the cutter with the conventional hardness and the cutter with the higher hardness can be respectively cut.

In an embodiment, for safety, the blade 110 at the rear end of the cutter body 100 is disposed at the bottom end of the cutter body 100, and both the front and rear ends of the cutter body 100 are smoothly transited. During the use process, the cutter head 130 and the cutter tail of the cutter body 100 can be prevented from hurting people. In addition, the surface of the handle 200 can be abraded or knurled, so that the sliding can be effectively prevented.

Referring to fig. 2, 3, 4 and 6, in particular, the handle 200 has a mounting end 210, a holding portion 220 and a handle tail 230 connected in sequence. The mounting end 210 is connected to the blade back 120 of the blade body 100 through the locking connection mechanism 300, and the holding portion 220 is disposed on the top of the mounting end 210 and extends in a direction away from the mounting end 210 in an inclined manner. The locking connection 300 includes a shaft 320 and a locking button 330. The shaft 320 is mounted on the blade back 120 and perpendicular to the plane of the blade back 120, and the mounting end 210 is rotatably mounted on the shaft 320.

Referring to fig. 2, 3, 4 and 5, two locking holes 121 are symmetrically formed on the blade back 120 at two sides of the rotating shaft 320. The mounting end 210 defines a lock mounting hole 212. The axial direction of lock mounting hole 212 intersects the plane of blade back 120. The locking button 330 is slidably inserted into the lock mounting hole 212, and an end of the locking button 330 is exposed out of the lock mounting hole 212 and inserted into any one of the locking holes 121.
