Description

Art designing knife with protective cover

Technical Field

The utility model relates to an art designing knife especially relates to an art designing knife with lag.

Background

The utility knife is commonly used in daily life and production, but accidents easily occur in the using process of the utility knife, and the exposed blade easily cuts skin and other objects.

Disclosure of Invention

The utility model provides an art knife with a protective cover; the problem of exist among the prior art and cut skin and other article easily is solved.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides an art knife with lag, includes blade and the scalable blade of installing in the inside of blade, its characterized in that: but the blade front end be equipped with the lag of back-and-forth movement, be equipped with the through-hole that link up around on the lag, the blade that stretches out from the blade front end can get into the through-hole setting, be connected with the connecting rod between blade and the lag.

The utility model discloses but be equipped with the lag of back-and-forth movement at the blade front end, the lag passes through the connecting rod to be connected with the blade, and interval between lag and the blade can freely be adjusted, and the blade in the region is used for the cutting between lag and the blade. Because the tool bit is wrapped by the protective sleeve, even if the tool bit is improperly operated, the blade slides to the skin or other objects, the protective sleeve is touched at first, and the probability of cutting injury is reduced. This state is fit for cutting article, when needs are carved with the tool bit, only need with lag and blade laminating, stretches out the user state that can form ordinary art designer's sword with the blade from lag front end through-hole. Therefore, the utility model is relatively safe to use.

Preferably, the connecting rod is positioned at the upper side of the telescopic track of the blade and is fixedly connected with the front end of the knife body. The upside of lag is equipped with T type groove, and the front end of connecting rod can be connected with T type groove cooperation. The connecting rod is preferably a sheet metal part, which is beneficial to reducing the projection area of the connecting rod in the distribution direction of the blades, reducing the influence on cutting and ensuring certain strength. The connecting rod in this scheme is fixed design, and its relative position with the blade can't change.

Preferably, the front end of the knife body is rotatably sleeved with a knife body sleeve, and the connecting rod is fixedly connected with the knife body sleeve; the outline of the through hole is a slender rectangle, and the outline of the protective sleeve is also a slender type; the protective sleeve is sleeved with a cylindrical sliding sleeve which can slide back and forth along the axial direction of the protective sleeve, the sliding sleeve is sleeved with a rotating sleeve in a rotating mode, and the rotating sleeve is fixedly connected with the connecting rod. In the scheme, a knife body sleeve and a rotating sleeve are fixedly connected to two ends of a connecting rod in a distributed manner and are respectively rotatably sleeved on the knife body and the sliding sleeve, so that the connecting rod can freely rotate and is used for avoiding entity collision in actual operation; the sliding sleeve can slide back and forth along the protective sleeve but cannot rotate, and the sliding sleeve cannot rotate under the state of being matched with the blade.

Preferably, the front end and the rear end of the protective sleeve are provided with limiting parts which can limit the sliding sleeve.

Therefore, compared with the prior art, the utility model has the following characteristics: 1. because the tool bit is wrapped by the protective sleeve, even if the tool bit is improperly operated to cause the blade to slide to the skin or other objects, the protective sleeve can be touched probably, and the probability of cutting injury is reduced.

Detailed Description

The technical solution of the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example 1: see fig. 1, an art designing knife with lag, including blade 1 and scalable blade 2 of installing in blade 1 inside, but blade 1 front end is equipped with the lag 3 of back-and-forth movement, is equipped with the through-hole 31 that link up around on the lag 3, and the blade 2 that stretches out from blade 1 front end can get into the through-hole 31 setting, is connected with connecting rod 4 between blade 1 and the lag 3.

Referring to fig. 2, the connecting rod 4 is located at the upper side of the telescopic track of the blade 2 and is fixedly connected with the front end of the blade body 1. The upside of lag 3 is equipped with T type groove 32, and the front end of connecting rod 4 can be connected with T type groove 32 cooperation. The connecting rod is preferably a sheet metal part, which is beneficial to reducing the projection area of the connecting rod in the distribution direction of the blades, reducing the influence on cutting and ensuring certain strength. The connecting rod in this scheme is fixed design, and its relative position with the blade can't change.

Example 2: referring to fig. 3, the utility knife with the protective sleeve comprises a knife body 1 and a blade 2 telescopically mounted in the knife body 1, wherein the protective sleeve 3 capable of moving back and forth is arranged at the front end of the knife body 1, a through hole 31 penetrating from front to back is formed in the protective sleeve 3, the blade 2 extending out of the front end of the knife body 1 can enter the through hole 31, and a connecting rod 4 is connected between the knife body 1 and the protective sleeve 3;

referring to fig. 4 and 5, the front end of the knife body 1 is rotatably sleeved with a knife body sleeve 11, and the connecting rod 4 is fixedly connected with the knife body sleeve 11; the through hole 31 is in a slender rectangle shape, and the outer contour of the protective sleeve 3 is also in a slender shape; cup joint columniform slip cap 5 on the lag 3, slip cap 5 can be followed 3 axial of lag and slided around, rotates on the slip cap 5 to cup joint and has rotated cover 6, rotates cover 6 and connecting rod 4 fixed connection.
