Examples

As shown in fig. 1-4, a bottom bone lock structure includes a blade 1 and a handle 9, the relative position relationship between the blade 1 and the handle 9 is divided into four states, i.e., a state a, a state B, a state C, and a state D, the blade 1 and the handle 9 are rotatably connected by a main shaft 7, when the blade 1 is in the state a, i.e., the open state, the upper surface and the lower surface of one end of the blade 1 close to the main shaft 7 are a blade locking mating line 2 and a blade unloading mating line 11, a bottom bone 3 is slidably connected inside the top end of the handle 9, a bottom bone front slideway 8 and a bottom bone rear slideway 10 are provided on the bottom bone 3, and the bottom bone front slideway 8 is located at one end of the bottom bone 3 close to the main shaft 7.

In this embodiment, the inside fixedly connected with of handle of a knife 9 is used for carrying out spacing preceding spacer 4 and back spacer 6 to end bone 3, preceding spacer 4 and back spacer 6 are located slide 8 behind end bone and the end bone respectively and slide 10 behind the end bone, one side fixedly connected with compression spring 5 that back spacer 6 is close to preceding spacer 4, compression spring 5 is located slide 10 behind the end bone, under compression spring 5's effect, make end bone 3 and sword strip 1 top tight, realize the locking, preceding spacer 4 and the spacing distance of end bone 3 back-and-forth movement of back spacer 6.

In this embodiment, the blade root locking and matching line 2 and the blade root unloading and matching line 11 are in a self-locking angle shape with the bottom bone 3, so that the blade 1 and the bottom bone 3 can be self-locked under the action of the compression spring 5 when the blade 1 is in the two states of a and D.

In this embodiment, the tang lock mating line 2 and the tang unload mating line 11 decrease in radius with respect to the tool spindle 7.

In the embodiment, when the knife strip 1 is tightly pressed against the knife root locking matching line 2, under the action of the compression spring 5, the knife strip 1 is in an open state and is locked with the bottom bone 3, namely, the knife strip 1 is in a state A, and when the knife strip 1 is tightly pressed against the knife root unloading matching line 11, under the action of the compression spring 5, the knife strip 1 is in a knife closing state and is locked with the bottom bone 3, namely, the knife strip 1 is in a state D.

In this embodiment, the top of the bottom frame 3 is provided with an anti-slip groove, which is convenient for the user to operate the bottom frame 3 to move.

The working principle is as follows: when the knife strip 1 is in the state of opening the use position A, under the action of the compression spring 5, the bottom rib 3 moves towards the knife tip direction under the matching of the bottom rib front slideway 8 and the front spacing shaft 4 as well as the bottom rib rear slideway 10 and the rear spacing shaft 6 until the bottom rib 3 and the knife strip 1 are tightly propped and are in the locking state, and under the action of the compression spring 5, the knife strip 1 and the bottom rib 3 can be automatically tightened, when the knife needs to be closed, the bottom rib 3 is pulled to overcome the force of the compression spring 5 to move along the direction of the knife handle 9, when the knife strip 1 leaves the knife root locking matching line 2, the knife strip 1 is in the state B, the knife strip 1 rotates anticlockwise along the knife spindle 7, at the moment, the compression spring 5 is in a certain compression state, when the knife strip 1 rotates to the state C, the knife strip 1 can push the bottom bone 3 to move along the knife root unloading matching line 11 under the action of the compression spring 5 until the knife strip 1 is in contact with the geometric shape on the bottom bone 3 to complete the closing function, at the moment, the compression spring 5 is still in a compression state to enable the bottom bone 3 and the knife handle 9 to form a resisting force state and not to be relatively loosened, on the contrary, the bottom bone 3 is pulled towards the knife handle 9, the knife strip 1 is held when the knife strip 1 leaves the knife root locking matching line 2 to enable the knife strip 1 to move clockwise, when the state B is reached, the bottom bone 3 moves along the knife root locking matching line 2 under the action of the compression spring 5 until the knife strip 1 is tightly contacted with the state A, and the usable locking state is completed.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
