Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the positionable monocular hole puncher in the present embodiment includes an upper handle 1 and a lower handle 3, a tool holder 2 is disposed between the upper handle 1 and the lower handle 3, and the upper handle 1 and the lower handle 3 are connected by a bolt 4. The paper feeding device is characterized in that a first paper feeding groove 21 is formed in the cutter holder 2, a second paper feeding groove 31 matched with the first paper feeding groove 21 is formed in the front end of the lower handle 3, when the cutter holder 2 is assembled on the lower handle 3, the first paper feeding groove 21 and the second paper feeding groove 31 are overlapped, and paper passes through the two paper feeding grooves which are overlapped with each other during punching. A knife core 22 is vertically inserted in the knife holder 2, the bottom of the front end of the lower handle 3 is hollowed to form a knife edge avoiding groove (not shown), a first elastic component 23 is sleeved between the knife core 22 and the knife holder 2, the first elastic component 23 is a spring, and the knife core 22 penetrates through the spring. The top of the knife core 2 is sleeved with a knife core protective sleeve 24.

The positionable single perforator further comprises a positioning ruler 5, and the positioning ruler 5 transversely extends from the side face of the lower handle 3. The positioning rule is made of plastic in this embodiment, but other materials may be used instead in other embodiments.

The positioning rule 5 can be used for positioning when the single-hole puncher punches holes one by one, so that the punching effect of the multi-hole puncher is obtained. Specifically, the tool apron 2 is provided with a slot for inserting the positioning ruler 5. The positioning rule 5 can be remounted after being taken down from the slot, so that the purpose of adjusting the extension direction of the positioning rule is achieved, and punching is convenient to be performed in different directions of paper.

A sliding groove 51 is arranged in the middle of the positioning ruler 5, a paper blocking block 52 is inserted in the sliding groove 51, the bottom of the paper blocking block 52 penetrates through the sliding groove 51 and then is connected with a fixed block 53, and a second elastic component 54 is arranged between the paper blocking block 52 and the fixed block 53, wherein the second elastic component is also a spring. The paper stop 52 can function as a position at the edge of the paper when the first hole is formed (refer to fig. 3).
