Description

Technical Field

[0001] The utility model relates to the technical field of cutter equipment, in particular to a cutter body structure of a protective film cutter. Background Art

[0002] A protective film cutter is a tool used to cut protective film or other thin film materials. Its blade is usually made of high-strength, durable metal or engineering plastic. The blade is generally fixed to the cutting part of the blade. The blade is usually designed with an ergonomic grip shape for the operator to hold comfortably and is anti-slip to increase operational safety.

[0003] The blade structure design provides the operator with a comfortable grip and operating feel, reducing wrist fatigue and discomfort. However, the existing blade structure setting is mostly used in only one holding method for continuous operation, and it is difficult to flexibly change the holding method, which leads to excessive wrist fatigue. Utility Model Content

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A knife body structure for a protective film cutter includes a knife body, a blade fixedly connected to one end below the knife body, a rotating shaft fixedly connected to one side of the knife body, one end of the rotating shaft rotatably connected to a rotating support base, a screw threadedly connected to one end inside the rotating support base, and a handle fixedly connected to one end above the screw.

[0007] Preferably, a rubber anti-slip sleeve is sleeved on the outside of the handle, and a screw limiting cover is threadedly connected to one end of the upper side of the handle.

[0008] Preferably, a finger pressure groove is provided at one end of the side surface of the rotating support base, and there are two groups of the finger pressure grooves, which are symmetrically arranged on both sides of the rotating support base.

[0009] Preferably, a thread groove one is provided on the other side of the cutter body, and the thread groove one is adapted to the screw rod. There are two groups of thread grooves one, which are symmetrically arranged on both sides of the cutter body.

[0010] Preferably, a second thread groove is provided at one upper end of the cutter body, and a through thread groove is provided in the middle of the rotation support base, and both the second thread groove and the through thread groove are adapted to the screw rod.

[0011] Preferably, an inner screw groove is threadedly connected to one end of the upper portion of the handle, and the inner screw groove is adapted to the screw limiting cover.

[0012] Preferably, the other end of the screw rod passes through the rotation support base and is threadedly connected to the screw rod. There are two groups of rotation support bases, which are symmetrically arranged on both sides of the cutter body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model fixes the screw rod with the rotating support base and the cutter body by rotating the rotating handle, so that the handle can be held by hand for cutting and shoveling operations, and the index finger can be placed in the finger pressure groove, which can better facilitate the index finger to exert force. The rotating handle is loosened to separate the screw rod from the cutter body, and the rotating support base can be rotated until it reaches the side of the cutter body. The rotating handle is then tightened to allow the screw rod to enter the thread groove, so that the holding method can be changed, so that the handle can be held by hand for cutting operations. The flexible change of the holding method can avoid the situation where the same holding method is used for a long time and the wrist is overly tired. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Reference Figure 1 - Figure 5In an embodiment of the present invention, a knife body structure of a protective film cutter includes a knife body 1, a blade 2 is fixedly connected to one end below the knife body 1, a rotating shaft 3 is fixedly connected to one side of the knife body 1, one end of the rotating shaft 3 is rotatably connected to a rotating support base 4, one end of the rotating support base 4 is threadedly connected to a screw 5, and one end above the screw 5 is fixedly connected to a handle 6.

[0023] A rubber anti-slip sleeve 7 is sleeved on the outside of the handle 6, and a screw limit cover 8 is threadedly connected to one end of the handle 6. A finger pressure groove 9 is provided at one end of the side of the rotating support base 4. There are two groups of finger pressure grooves 9, which are symmetrically arranged on both sides of the rotating support base 4. A thread groove 10 is provided on the other side of the cutter body 1, and the thread groove 10 is adapted to the screw 5. There are two groups of thread grooves 10, which are symmetrically arranged on both sides of the cutter body 1. A thread groove 2 11 is provided at one end above the cutter body 1, and a threaded through groove 12 is provided in the middle of the rotating support base 4. Both the thread groove 2 11 and the threaded through groove 12 are adapted to the screw 5. An inner thread groove 13 is threadedly connected to one end of the handle 6, and the inner thread groove 13 is adapted to the screw limit cover 8. The other end of the screw 5 passes through the rotating support base 4 and is threadedly connected to the screw 5. There are two groups of rotating support base 4, which are symmetrically arranged on both sides of the cutter body 1. Adopting the above scheme: by loosening the rotating handle 6 to make the screw 5 disengage from the cutter body 1, the rotating support base 4 can be rotated until it reaches the side of the cutter body 1, and then tightening the rotating handle 6 to make the screw 5 enter the thread groove 10, so that the holding method can be changed, so that the cutting operation can be performed by holding the handle 6.

[0024] The working principle of the present invention is as follows: when in use, by rotating the rotating handle 6, the screw 5 fixedly connected thereto passes through the threaded through groove 12 and enters the threaded groove 11, the rotating support base 4 can be fixedly connected to the cutter body 1, so that the handle 6 can be held by hand for cutting and shoveling operation, and the index finger can be pressed against the finger pressure groove 9, which can better facilitate the index finger to exert force, loosen the rotating handle 6 to make the screw 5 disengage from the cutter body 1, and then the rotating support base 4 can be rotated until it reaches the side of the cutter body 1, and then tighten the rotating handle 6 to make the screw 5 enter the threaded groove 10, so that the holding direction can be changed. The cutting operation can be performed by holding the handle 6. By flexibly changing the method, it is possible to avoid using the same holding method for a long time, which may cause excessive fatigue of the wrist. The holding method can also be changed according to actual operation needs, making it easier and more practical to use the entire cutter body 1. By loosening and removing the screw limit cover 8, the rubber anti-slip cover 7 can be put on the handle 6, and then tightening the screw limit cover 8 to limit and fix the rubber anti-slip cover 7, which can prevent the staff from slipping during operation, and is more comfortable when exerting force. It is also convenient to replace the rubber anti-slip cover 7 after long-term use.
