Form recording device

Abstract

The invention discloses a form recording device which comprises a shell provided with a head cover and a tail cover, a fixing frame, an inner pipe sleeved with an inner cavity of the shell, a center shaft, a saw blade and a pen. An inversion-preventing device preventing a form roll from being inversed is arranged between the inner pipe and the center shaft. An inner pipe through groove for the form roll to penetrate out is formed in the inner pipe in the length direction. A saw tooth edge of the saw blade is arranged at the position of the inner pipe through groove. A shell through hole for the form roll to penetrate out is formed in the position, corresponding to the inner pipe through groove, of the shell. The pen is arranged in a hollow inner cavity of the center shaft, and the tail portion of the pen stretches out of the tail cover. The pen is detachably connected with the side wall of the fixing frame. The inversion-preventing device is composed of a ratchet wheel installed at the upper portion of the center shaft in a sleeving manner, an elastic piece arranged in a groove in the inner wall of the inner pipe and matched with the ratchet wheel, and a limiting pillar arranged on one side of the elastic piece. The form recording device is compact in structure, forms can be easily stored and used in a classified manner, in addition, the form recording device can be used in a production field with the relatively severe working environment, taking and placing are convenient and quick, and recording is convenient.

Description

technical field [0001] The invention relates to a recording device, in particular to a form recording device. Background technique [0002] In daily life and work, people often need to use various forms, but after the blank forms are used, they are often lost due to improper storage, or due to limited storage space, different types are often stacked together, which is inconvenient to find when using. Especially in production sites with relatively harsh working environments such as casting and machining, it is easy to come into contact with oil and pollute forms. In severe cases, the entire stack of forms will be scrapped, resulting in greater waste. In addition, a pen needs to be used when the form is recorded, but under normal circumstances, the pen and the form are stored separately, and it is often necessary to find another pen when recording, which causes inconvenience. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
