Description

Technical Field

[0001] This utility model belongs to the field of clamp pliers technology, specifically relating to a multi-functional clamp pliers. Background Technology

[0002] Clamping pliers are generally used on ear clamps to tighten them. When it is necessary to remove the ear clamp, wire cutters are needed to cut it. If the ear clamp fails to install, wire cutters are needed to cut the damaged ear clamp. Switching between clamping pliers and wire cutters is a cumbersome and inefficient process.

[0003] To avoid the hassle of changing tools, the clamp head is designed with both a clamping position and a wire-cutting position. The handle is a ratchet structure to adjust clamping and wire cutting. However, this structure is limited by the ratchet and is only suitable for clamping standard parts. It cannot be used in multiple scenarios. Furthermore, the clamping and wire-cutting positions need to be changed, which is inconvenient for operators to use the tool. In addition, the dual-position setting increases the mold opening cost. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figure 1-3 As shown, the present invention provides a multifunctional clamp pliers, including a clamp pliers body. The clamp pliers body is used to clamp or cut ear-shaped clamps 12. The ear-shaped clamps 12 have ear ends 9 formed on them for clamping or cutting by the clamp pliers body. The clamp pliers body includes two rotatably connected left jaws 6 and right jaws 5. The left jaws 6 and right jaws 5 are provided with clamping and cutting parts 10 on opposite sides of their ends. The clamping and cutting parts 10 include a cutting blade and a jaw 7 formed on its inner side to accommodate the ear ends 9.

[0023] When clamped, the ear end 9 is placed in the jaws 7, and the clamping shearing part 10 squeezes the contact part with the ear end 9, causing the contact part to deform and clamp; when cutting, the top of the ear end 9 is placed between the two blades of the shearing blade, and the clamping shearing part 10 squeezes the contact position with the top of the ear end 9, causing the top of the ear end 9 to be cut off along the width direction.

[0024] Combination Figure 1 and Figure 3 As shown, both the left jaw 6 and the right jaw 5 form a beak structure through the jaws 7, and the two clamping and shearing parts 10 are respectively located on the inner side of the ends of the two beak structures.

[0025] Combination Figure 1-3 As shown, a fixing plate 4 is also provided on one side of the left jaw 6 and the right jaw 5, and two rotating parts 3 are provided on the fixing plate 4 for rotating the left jaw 6 and the right jaw 5.

[0026] Combination Figure 3 and Figure 5 As shown, the ear tip 9 is connected in series with the ear-shaped clamp 12.

[0027] Combination Figure 3 and Figure 5 As shown, the ear tip 9 is rectangular before deformation and becomes a T-shaped structure after deformation.

[0028] As described above, when using the clamping pliers provided by this utility model, the ear-shaped clamp 12 is placed on the pipe fitting 11, the ear end 9 is placed into the clamping jaw 7, and the left clamping head 6 and the right clamping head 5 are clamped inward by the rotating part 3, so that the ear end 9 is transformed from a rectangle into a T-shaped structure. During the deformation process, the ear-shaped clamp 12 is tightened, so that the ear-shaped clamp 12 is clamped on the pipe fitting 11.

[0029] Furthermore, to prevent the ear tip 9 from shifting position when locked, refer to Figure 1-3 As shown, the left jaw 6 and right jaw 5 are also provided with a baffle 8 on the side opposite to the fixing plate 4 to position the ear tip 9, and the baffle 8 is located on the outside of one side of the jaw 7. When the ear tip 9 is inserted from one side of the jaw 7, the baffle 8 limits the position of the ear tip 9, so that the ear tip 9 is stably placed in the jaw 7, avoiding incomplete clamping of the ear tip 9 and thus preventing damage to the ear tip 9.

[0030] As described above, when using the clamp pliers provided by this utility model to cut, the left clamp head 6 and the right clamp head 5 are respectively positioned on both sides of the top of the ear end 9. When the left clamp head 6 and the right clamp head 5 are close to each other, the shearing blade of the clamping shearing part 10 is used to cut the width direction of the top of the ear end 9, thereby releasing the clamping state of the ear-shaped clamp 12 on the pipe fitting 11.

[0031] In this utility model, combined with Figure 1-3 As shown, each rotating component in this embodiment includes a rivet 15 and two rivet ends 14 stamped at both ends of the rivet 15. The rivet ends 14 abut against the fixing plate 4 and the baffle 8. The rivet 15 passes through the mounting holes 13 respectively provided on the left and right sides of the fixing plate 4, and passes through the left clamp head 6, the right clamp head 5 and the baffle 8.

[0032] As described above, using the rotating component provided by this utility model, the left clamp head 6 and the right clamp head 5 are rotatably installed between the fixed plate 4 and the baffle 8 by the rivet rod 15 in the rotating component. During this process, the two ends of the rivet rod 15 are stamped by the stamping equipment, thereby forming a rivet end 14 at the end of the rivet rod 15 that abuts against the fixed plate 4 and the baffle 8, preventing the fixed plate 4, the baffle 8, the left clamp head 6 and the right clamp head 5 from becoming loose. At the same time, the rivet rod 15 enables the left clamp head 6 and the right clamp head 5 to rotate between the fixed plate 4 and the baffle 8, making it easier for the ends of the left clamp head 6 and the right clamp head 5 to move closer or further apart.

[0033] In this utility model, combined with Figure 1-3 As shown, this embodiment includes two identical left grip arm 1 and right grip arm 2. The left jaw 6 and right jaw 5 are integrally formed with one end of the right grip arm 2 and the left grip arm 1, respectively. A gripping area for holding is formed between the left grip arm 1 and the right grip arm 2.

[0034] Combination Figure 1-3 As shown, the left grip arm 1 and the right grip arm 2 are both provided with grip grooves on opposite sides for holding; the left jaw 6 and the right jaw 5 of the left grip arm 1 and the right grip arm 2 are all provided with weight-reducing grooves for weight reduction. The weight reduction grooves reduce the weight of the clamp without affecting its performance, making the clamp easier to use, and the grip grooves make it easier for the user to hold and use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
