Technical Field

[0001] This utility model belongs to the field of hardware manufacturing, specifically a foldable pedal-type bolt cutter. Background Technology

[0002] Pliers are mainly used for clamping parts for riveting, welding, grinding and other processing. Their features include a locking jaw that can generate a large clamping force to prevent the clamped parts from loosening. The jaws also have many adjustable positions to clamp parts of different thicknesses. In addition, they can also be used as a wrench.

[0003] Existing bolt cutters typically have short handles, making them difficult to use as wrenches when the clamped part is difficult to turn due to rust or other reasons. Therefore, this application proposes foldable pedal bolt cutters, which can disassemble parts by increasing torque and facilitating the use of a foot pedal. Utility Model Content

The foldable pedal is composed of a support frame, a folding arm and a limiting pin, wherein the folding arm is connected to the support frame through a damping shaft, and the support frame is sleeved on the main clamp arm and connected to the main clamp arm through the limiting pin.

[0006] Preferably, one side of the support frame is provided with a groove that matches the main clamp arm, and the side of the support frame away from the groove is provided with a mounting groove that matches the folding arm. The folding arm is located inside the mounting groove, and one end of the support frame is provided with pin hole one and pin hole two that match the positioning through hole and the limiting pin one.

[0007] Preferably, an auxiliary support matching the folding arm is fixedly provided at one end of the support frame near the damping axis. The auxiliary support and the support frame are an integral structure. A buckle plate is fixedly provided at one end of the folding arm away from the damping axis. The buckle plate and the folding arm are an integral structure.

[0008] Preferably, the support frame is fixedly provided with ear plate one and ear plate two at the middle position on the side near the body of the pliers. Both ear plate one and ear plate two are provided with pin holes three. A limit pin two is provided between ear plate one and ear plate two. Ear plate one and ear plate two are integral structures with the support frame. Limit pin one and limit pin two are both composed of a T-shaped pin body and an O-shaped safety pin. The O-shaped safety pin is installed at one end of the T-shaped pin body.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by setting a foldable pedal composed of a support frame, a folding arm and a limiting pin, this utility model can be installed with the body of the pliers. When disassembling parts, it can increase the torque and make it easier for workers to apply pressure instantly with their feet, thereby improving the convenience of disassembling parts.

Detailed Implementation

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0013] See Figures 1 to 4 As shown, the bolt clamps in this embodiment include a bolt clamp body 1 and a foldable pedal 2. The foldable pedal 2 is mounted on the main clamp arm 3 of the bolt clamp body 1. The main clamp arm 3 has a positioning through hole 4 that matches the foldable pedal 2. The foldable pedal 2 is composed of a support frame 5, a folding arm 6 and a limiting pin 7. The folding arm 6 is connected to the support frame 5 through a damping shaft 8. The support frame 5 is sleeved on the main clamp arm 3 and connected to the main clamp arm 3 through the limiting pin 7. A groove 9 that matches the main clamp arm 3 is opened on one side of the support frame 5. A mounting groove 10 that matches the folding arm 6 is opened on the side of the support frame 5 away from the groove 9. The folding arm 6 is located inside the mounting groove 10. A pin hole 11 and a pin hole 12 that match the positioning through hole 4 and the limiting pin 7 are opened at one end of the support frame 5. When in use, the support frame 5 is fitted onto the main clamp arm 3 of the pliers body 1, so that the limit pin 7 is inserted into the pin hole 11, the pin hole 2 12 and the positioning through hole 4 to achieve connection limit. Then, the folding arm 6 is rotated around the damping shaft 8 and pulled out from the inside of the mounting groove 10, which can increase the torque and make the operation more labor-saving. After the extension, it is also convenient for the staff to operate the pliers by foot pedal, which is more suitable for disassembling parts with high connection strength and improves the convenience of operation. An auxiliary support 13 matching the folding arm 6 is fixedly installed at one end of the support frame 5 near the damping shaft 8. The auxiliary support 13 and the support frame 5 are an integral structure. The auxiliary support 13 can provide auxiliary support for the folding arm 6 and improve the stability of the folding arm 6. A buckle plate 14 is fixedly installed at one end of the folding arm 6 away from the damping shaft 8. The buckle plate 14 and the folding arm 6 are an integral structure, which makes it easy to remove the folding arm 6 from the inside of the mounting groove 10. Ear plate 15 and ear plate 26 are fixedly installed in the middle position of the support frame 5 near the body of the pliers 1. Both ear plate 15 and ear plate 216 have pin holes 317. Limiting pin 218 is provided between ear plate 15 and ear plate 216. Ear plate 15 and ear plate 216 are integral with the support frame 5. Limiting pin 17 and limiting pin 218 are both composed of T-shaped pin body 19 and O-shaped safety pin 20. O-shaped safety pin 20 is installed at one end of T-shaped pin body 19. After the support frame 5 and the main clamp arm 3 are installed, the second limit pin 18 can be inserted into the ear plate 15 and the second ear plate 16. At this time, the second limit pin 18 is located on the other side of the main clamp arm 3, which realizes the function of auxiliary limit. When the staff applies force by stepping, it avoids the support frame from rebounding, thus improving safety and stability. The T-shaped pin body 19 and the O-shaped safety pin 20 are connected to each other, which can improve the stability of the limit connection.

[0014] During operation, the foldable pedal, consisting of a support frame, a folding arm, and a limiting pin, can be installed with the main body of the pliers. This increases torque during parts disassembly and allows workers to apply pressure instantly with their feet, improving the ease of disassembly. A groove allows it to engage with the main pliers arm, and a mounting slot allows for the installation of the folding arm. An auxiliary support enhances the support of the folding arm, increasing the stress points and improving its stability. A snap-on plate facilitates the removal of the folding arm from the mounting slot. Ear plates one and two, a pin hole three, and a limiting pin two limit the support frame, preventing it from springing back when workers apply force by foot, thus improving stability.

[0015] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
