Abstract
Description
Technical Field
[0001] The utility model relates to a pipe clamp, in particular to a multifunctional casing heavy-duty pipe clamp, which belongs to the technical field of hand tools. Background Art
[0002] In daily use of pipe pliers, there are many situations where the working force is large and the length of the pliers handle needs to be extended. Retractable pipe pliers have been disclosed in the prior art, but because they are one-piece retractable, the telescopic force of this type of pipe pliers is limited. When the pliers handle reaches the maximum length, the overall strength of the pliers handle will also decrease, affecting the construction effect and reducing the construction efficiency. Utility Model Content
[0003] Technical purpose: In order to overcome the deficiencies in the prior art, the utility model provides a multifunctional casing heavy-duty pipe clamp, which, without reducing the strength of the clamp handle itself, adds a casing to extend the length of the clamp handle to meet the use requirements.
[0004] Technical solution: To achieve the above-mentioned purpose, the utility model discloses a multifunctional casing heavy-duty pipe pliers, including a pliers handle body, a fixed jaw, a movable jaw and an adjusting nut, wherein the fixed jaw is connected to one end of the pliers handle body, and the movable jaw includes an integrally formed hook head and a vertical portion, the hook head is opposite to the fixed jaw, the vertical portion is slidably connected to the pliers handle body, and is threadedly connected to the adjusting nut through its surface thread, and also includes a sleeve, and the surface of the pliers handle body is provided with a threaded portion for connecting with the sleeve, and the sleeve is sleeved and connected to the pliers handle body.
[0005] Furthermore, an annular groove is also provided on the surface of the clamp handle.
[0006] Furthermore, the annular groove is arranged in the middle of the pliers handle body, and the annular groove is arranged adjacent to the threaded portion.
[0007] Furthermore, a plurality of ridges are arranged in the annular groove.
[0008] Furthermore, the surface of the pliers handle body is provided with a plurality of polygonal wrench holes of different sizes.
[0009] Furthermore, an inner hole is provided at one end of the pliers handle body close to the wrench hole.
[0010] Furthermore, the clamping area surrounded by the hook head and the fixed jaw is trapezoidal.
[0011] The utility model provides a threaded portion on the surface of the pliers handle body and adds a sleeve to connect with the pliers handle body. Under the premise of extending the pliers handle body, the strength of the pliers handle body will not be reduced, thus meeting the use requirements. An annular groove is provided on the surface of the pliers handle body for connecting with a wire rope, and convex ridges are provided to increase the friction with the wire rope and enhance the stability. The threaded portion is provided in the middle of the pliers handle body to avoid bending or deformation of the pliers handle body during use. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the utility model (I);
[0013] Figure 2 This is a schematic structural diagram of the utility model (II).
[0014] In the figure, 1, the pliers handle body; 2, the fixed jaws; 3, the movable jaws; 301, the hook part; 302, the vertical part; 4, the adjusting nut; 5, the sleeve; 6, the threaded part; 7, the annular groove; 8, the convex ridge; 9, the wrench hole; 10, the inner hole. DETAILED DESCRIPTION
[0015] The following is combined with Figure 1 To Attachment Figure 2 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.
[0016] A multifunctional casing heavy-duty pipe pliers, comprising a pliers handle body 1, a fixed jaw 2, a movable jaw 3 and an adjusting nut 4, wherein the fixed jaw 2 is connected to one end of the pliers handle body 1, and the movable jaw 3 comprises an integrally formed hook portion 301 and a vertical portion 302, wherein the hook portion 301 is opposite to the fixed jaw 2, and the vertical portion 302 is slidably connected to the pliers handle body 1 and is threadedly connected to the adjusting nut 4 through its surface thread, and further comprises a sleeve 5, and a threaded portion 6 for connecting to the sleeve 5 is provided on the surface of the pliers handle body 1, and the sleeve 5 is sleeved and connected to the pliers handle body 1.
