[0019] The utility model is described in detail below with reference to the drawings and examples. Embodiments

[0020] An easy-to-insert book rod clamp, as shown in Figure 1 and Figure 3 , comprises a spine 1 in the middle and clamping wings 2 on both sides, the spine 1 and the clamping wings 2 are integrally formed to form a book rod clamp main body, and the book rod clamp main body is made of LDPE material. The LDPE material has good softness and ductility, which makes it perform well in the application as a book rod clamp. When the clamping wings 2 are spread apart during the process of inserting the book rod clamp into the book spine, the entire book rod clamp is not easy to break. The side of the clamping wings 2 away from the spine 1 is provided with a low-friction coefficient sleeve. The surface of the low-friction coefficient sleeve is used to abut against the book. During the process of inserting the book rod clamp into the book spine, the book rod clamp is first deformed to spread apart the book clamping opening on one side of the book rod clamp, and then the book spine is inserted into the book clamping opening of the book rod clamp. At this time, the low-friction coefficient sleeve on the clamping wing 2 abuts against the book. Then the book rod clamp and the book are moved towards each other. During this process, the low-friction coefficient sleeve and the book move relatively to generate friction. However, because the surface of the low-friction coefficient sleeve has a low friction coefficient, the process of inserting the book rod clamp is easier than that of the existing book rod clamp. The low-friction coefficient sleeve is a Teflon plastic sleeve 3. Teflon plastic has a low friction coefficient and is an ideal material for manufacturing high-temperature lubricating materials. The friction coefficient of the Teflon plastic sleeve 3 is extremely small, only 1 / 5 of that of polyethylene, which is the lowest among solid materials.

[0021] As shown in Figure 1 and Figure 3 , the Teflon plastic sleeve 3 is in the shape of a profile. Since the spine 1 and the clamping wings 2 are integrated and made of plastic profile, and the Teflon plastic sleeve 3 is in the shape of a profile, on the one hand, the molding of the Teflon plastic sleeve 3 is relatively simple, and on the other hand, different lengths can be cut to easily match the book rod clamp main body of different lengths, so that the Teflon plastic sleeve 3 and the book rod clamp main body have better adaptability.

[0022] Further, as shown in Figure 1 and Figure 3As shown, the surface of the clamping wing 2 is integrally formed with several anti-skid ribs 4 arranged along the length direction thereof, which can play an anti-skid role and facilitate holding the main body of the book rod clamp. The Teflon plastic sleeve 3 is fixedly connected with one side of the clamping wing 2. Specifically, the Teflon plastic sleeve 3 is arranged in a U-shaped cross section and forms a cavity 5 inside for accommodating the clamping wing 2. A clamping groove 6 is arranged on the inner wall of the cavity 5 along the length direction thereof, and the clamping groove 6 is used for accommodating one anti-skid rib 4. The clamping and fixing mode makes the fixing of the clamping wing 2 and the Teflon plastic sleeve 3 relatively simple. Specifically, one end of the clamping wing 2 is clamped into the cavity 5 of the Teflon plastic sleeve 3, and one anti-skid rib 4 is clamped into the clamping groove 6. Then, the Teflon plastic sleeve 3 is moved along the length direction of the clamping wing 2 to complete the installation of the Teflon plastic sleeve 3 and the clamping wing 2. The movement of the anti-skid rib 4 is limited by the clamping groove 6, so that the clamping wing 2 is not easy to be separated from the cavity 5 and can keep the Teflon plastic sleeve 3 and the clamping wing 2 in a connected state.

[0023] As shown in Figure 2 and Figure 3 The two ends of the Teflon plastic sleeve 3 and the clamping wing 2 are flush, and the two ends of the Teflon plastic sleeve 3 are fixedly connected with soft glue fixing blocks 7. After the clamping and fixing of the Teflon plastic sleeve 3 and the clamping wing 2 are completed, liquid silicone is applied to the ends of the Teflon plastic sleeve 3 and the clamping wing 2, and after solidification, the soft glue fixing blocks 7 are formed to fix the Teflon plastic sleeve 3 and the clamping wing 2. The soft glue fixing blocks 7 can limit the relative movement of the Teflon plastic sleeve 3 and the clamping wing 2 in the length direction thereof, so that the Teflon plastic sleeve 3 and the clamping wing 2 do not move relatively during the clamping of the book rod clamp into the book spine, and the installation and fixing of the book rod clamp are more convenient.

[0024] The preferred embodiments of the present application are described above, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
