Abstract

An improved structure for the handle of a binding machine includes a main arm, a clamp arm, an operating handle and a protective cover. The main arm can pull out the adhesive tape from the front end, the main arm is pivoted with a clamp arm, and the clamp arm is connected with the main arm by a spring, so that the clamp arm is normally opened relative to the main arm. The front end of the pliers arm is provided with a tape holding device and a blade. When the pliers arm pivots toward the main arm, the tape holding device can pull the tape out of the main arm by the tape holding device and cut the tape with the blade. The operating handle is pivoted on the pliers arm with a pivot, and is provided with a hook part located on the main arm for the user to hold the operating handle to control the action of the pliers arm. The protective cover is fixed on both sides of the operating handle and only covers the area between the pivot and the hook.

Description

Improved structure of strapping machine handle

The invention relates to hand tools, especially a binding machine.

Figure 7 shows a conventional strapping machine, which has a main arm 71, a clamp arm 72, an operating member 73 and a protective cover 74. The pliers arm 72 is pivoted to the main arm 71, the operating member 73 is pivoted to the pliers arm 72, the protective cover 74 is fixed on the operating member 73, and extends backwards by an extension 741 whose length is longer than the operating member 73 , And then form a handle for pressing. The main arm 71 can pull out the tape from the front end, and the front end of the clamp arm 72 is provided with a tape holding device 721. When the extension section 741 is pressed, the operating member 73 is forced to push, which in turn drives the clamp arm 72 to pivot toward the main arm 71 , And the clamp arm 72 can use the tape holding device 721 to pull out the tape from the main arm 71 when it pivots toward the main arm 71, and cut the tape after looping the object.

In the structure of the above-mentioned conventional strapping machine, the handle is integrally formed by the extension 741 of the protective cover 74, and the extension 741 of the protective cover 74 is generally made of plastic, which has insufficient strength and may bend after being pressed for a long time. If it is damaged, it can no longer be used.

In view of this, how to improve the above-mentioned problem is the primary problem to be solved by the present invention.

The main purpose of the present invention is to provide an improved structure for the strapping machine handle, the protective cover is on one side of the operating handle and covers the area between the pivot and the hook, so as to prevent the intrusion of foreign matter to achieve the protection effect.

In order to achieve the foregoing objective, the present invention provides an improved structure for the strapping machine handle, which includes: A main arm, which can pull out the tape from the front end; A pliers arm, which is pivoted on the main arm, and a spring is connected between the pliers arm and the main arm, so that the pliers arm is normally opened relative to the main arm; the front end of the pliers arm is provided with a tape holding device And a blade, the pliers arm can use the tape holding device to pull the tape from the main arm when pivoting toward the main arm, and cut the tape with the blade; An operating handle, which is pivoted on the pliers arm with a pivot, and is provided with a hook portion located on the main arm for the user to hold the operating handle to control the action of the pliers arm; A protective cover is fixed on both sides of the operating handle and only covers the area between the pivot and the hook.

The above-mentioned objects and advantages of the present invention can be easily understood from the detailed description of the selected embodiments and the accompanying drawings.

Please refer to Figures 1 and 2, which shows the improved structure of the strapping machine handle provided by the present invention, which includes a main arm 1, a clamp arm 2, an operating handle 3 and a protective cover 4. The rear end of the main arm 1 is provided with a chamber 11 for placing the tape roll, so that the tape can be pulled out from the front end of the main arm 1. The front end of the main arm 1 is provided with a blade 12. The pliers arm 2 is pivoted to the main arm 1, and a spring 13 is used to connect the pliers arm 2 and the main arm 1. The spring 13 makes the pliers arm 2 normally open relative to the main arm 1.

On the other hand, the operating handle 3 is made of metal and is pivoted on the clamp arm 2 with a pivot 31. The operating handle 3 extends backwards with an extension 32 for the user to press, and extends forwards with a hook portion 33. The hook portion 33 can be positioned on a blocking column 14 on the main arm 1 to restrict the clamp arm 2 The opening angle relative to the main arm 1.

The front end of the pliers arm 2 is provided with a tape holding device 21. When the user presses the extension 32 of the operating handle 3, as shown in Figures 3 and 4, the operating handle 3 pushes the pliers arm 2 toward the main arm. 1 Pivot, and then use the tape holding device 21 to pull out the tape 5 from the main arm 1. Next, wrap the tape 5 around an object 6 as shown in Figure 5, and press the extension 32 again, then the operating handle 3 will push the pliers arm 2 toward the main arm 1 again as shown in Figure 6. Pivot, and then cut the tape 5 with the blade 12.

The two sides of the above-mentioned operating handle 3 are respectively locked with a protective cover 4 with screws 41 to form a protective effect to prevent foreign matter from intruding and causing unsmooth operation. Furthermore, the protective cover 4 only covers the area between the pivot 31 and the hook portion 33, that is, the area most in need of protection, so that the material cost can be reduced on the premise that the protection effect can be achieved.

However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention. Any replacement of equivalent elements should still belong to the scope of the present invention.

In summary, those skilled in the art can understand that this invention can clearly achieve the aforementioned purpose, and that it has actually complied with the provisions of the Patent Law, so it is necessary to file an application in accordance with the law.
