Description

Technical Field

[0001] This utility model relates to the field of cutting pusher technology, and in particular to a foldable and retractable T-shaped cutting pusher. Background Technology

[0002] Traditional integrated cutting machines are typically designed with fixed dimensions, resulting in large size and heavy weight. This causes significant inconvenience for users when they need to move the machine or switch between different work sites. Furthermore, due to the integrated design of the cutting components and the machine body, the cutting length is limited by the overall size of the equipment, making it impossible to meet the needs of continuous cutting of long materials. This limitation is particularly evident when processing large plates, long strips of materials, or performing on-site processing, severely restricting the efficiency and flexibility of cutting operations. Therefore, there is an urgent need in the market for a cutting tool that is both portable and adaptable to different cutting length requirements to improve the convenience and efficiency of cutting operations.

[0003] To address this issue, a cutting pusher is currently available on the market. It features a T-shaped structure, including a fixed rod, a ruler rod perpendicular to the fixed rod, and a blade holder that can move along the ruler rod. Rollers are installed on the sides and top of the fixed rod. The side rollers are designed at a 15° angle, while the four rows of rollers on the top are perpendicular at 90°. These two sets of pulleys effectively ensure smooth cutting and allow for cutting according to the length of the object, without length limitations. However, this T-shaped structure relies on fasteners for connection, meaning that users must ensure sufficient space to operate these fasteners when disassembling, transporting, or storing the object. This undoubtedly increases the complexity and inconvenience of use, especially in situations with limited space or frequent handling, where quick disassembly and storage become a major challenge.

[0004] Therefore, given that the existing cutting pushers rely on fasteners for connection, which makes disassembly, transportation, or storage inconvenient and requires a large operating space, a foldable T-shaped cutting pusher can be designed to maintain smooth cutting and facilitate quick disassembly, storage, and transportation. Utility Model Content

[0005] To overcome the problem that existing cutting pushers rely on fasteners for connection, making them inconvenient to disassemble, transport, or store, and requiring a large operating space.

[0006] The technical solution of this utility model is as follows: a foldable and retractable T-shaped cutting pusher, including a fixed rod and a ruler rod. A slidable knife holder is sleeved on the outside of the ruler rod. A knife head is installed at the lower end of the knife holder. It also includes a plug. The ruler rod is foldably and rotatably connected to the upper end of the fixed rod through the plug. The height of the plug is greater than the thickness of the ruler rod. Several sets of first pulleys are vertically installed at the lower end of the top of the fixed rod. A second pulley set with an inclination of 15° is provided on the side wall of the fixed rod. The fixed rod and the ruler rod are fixedly connected by fasteners.

[0007] Preferably, the cutting pusher is removed, and the ruler rod is rotated through the insert to make the fixed rod and the ruler rod perpendicular to each other. The fixed rod and the ruler rod are then fixed with fasteners. During use, the second pulley group on the side of the fixed rod is close to the side of the object being cut, and the first pulley group is placed on the surface of the object being cut to ensure smooth cutting. The blade holder is slid to a specific scale position on the ruler rod, and the fixed rod and the ruler rod are pushed. The blade head slides synchronously to cut the item.

[0008] Preferably, the upper end of the fixing rod is provided with a sliding groove, a slider is slidably connected in the sliding groove, a pin is fixedly connected to the upper end of the slider, and a locking hole matching the fastener is provided on the rear side of the upper end of the fixing rod.

[0009] Preferably, a first magnet is fixedly connected to the lower end of the ruler rod, and a second magnet that is magnetically connected to the first magnet is fixedly connected to the upper end of the fixed rod.

[0010] Preferably, the upper end of the fixed rod is provided with a locking component for limiting the movement of the ruler rod.

[0011] Preferably, the locking assembly includes a fixed locking block and a locking seat fixedly connected to the left and right recesses on the upper end of the fixed rod. Several first springs are installed in the upper opening of the locking seat, and a locking limit block is fixedly connected to the upper end of the first spring.

[0012] Preferably, the tool holder is internally threaded with an adjusting handwheel that abuts against the scale rod, and anti-collision pads are installed on the tool holder.

[0013] Preferably, a second spring is fitted onto the outer side of the insertion post, and the second spring is positioned between the insertion post and the scale rod.

[0014] The beneficial effects of this utility model are as follows: The design of the fixed rod and the ruler rod being foldably and rotatably connected via a plug allows the pusher to be easily folded and stored when not in use, greatly reducing its size and weight, making it easy to carry and transport. Secondly, the sliding blade holder, sleeved on the outside of the ruler rod, allows users to adjust the position of the blade holder as needed, achieving precise cutting of materials of different lengths, no longer limited by the size of the equipment itself. Furthermore, the 15° inclined second pulley group on the side of the fixed rod and the first pulley group vertically installed at the top and bottom ensure smooth sliding and accurate positioning during the cutting process, improving cutting quality and efficiency. It is not only portable and easy to use, but also adaptable to different length cutting needs, bringing greater convenience and efficiency to cutting operations. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] Please see Figures 1-2This utility model provides an embodiment of a foldable and retractable T-shaped cutting pusher, including a fixed rod 1 and a ruler rod 2. A slidable blade holder 3 is sleeved on the outer side of the ruler rod 2, and a blade head 4 is installed at the lower end of the blade holder 3. It also includes a post 7. The upper end of the fixed rod 1 is foldably and rotatably connected to the ruler rod 2 via the post 7. The height of the post 7 is greater than the thickness of the ruler rod 2. Several sets of first pulley groups 5 are vertically installed at the lower top of the fixed rod 1. A second pulley group 6 inclined at 15° is provided on the side wall of the fixed rod 1. The fixed rod 1 and the ruler rod 2 are fixedly connected by fasteners 8. The upper end of the tool holder 1 has a groove 9, and a slider 10 is slidably connected in the groove 9. A pin 7 is fixedly connected to the upper end of the slider 10. A locking hole 11 matching the fastener 8 is opened on the rear side of the upper end of the fixed rod 1. A first magnet 12 is fixedly connected to the lower end of the scale rod 2. A second magnet 13 magnetically connected to the first magnet 12 is fixedly connected to the upper end of the fixed rod 1. An adjusting handwheel 15 that abuts against the scale rod 2 is threaded into the tool holder 3. An anti-collision pad 16 is installed on the tool holder 3. A second spring 18 is sleeved on the outside of the pin 7. The second spring 18 is located between the pin 7 and the scale rod 2.

[0024] During operation, loosen the fastener 8 to remove it from the locking hole 11. Rotate the scale rod 2 via the insert 7 to separate the first magnet 12 and the second magnet 13. The scale rod 2 and the fixing rod 1 unfold from their folded state to a mutually perpendicular position. Secure the fixing rod 1 and the scale rod 2 together using the fastener 8 to prevent accidental rotation or loosening during cutting. Place the second pulley group 6 on the side of the fixing rod 1 against the side of the object being cut, serving as a guide and positioning reference. Simultaneously, place the first pulley group 5 on the surface of the object being cut. Utilize the rolling characteristics of the pulley group to ensure smooth sliding of the cutting pusher during cutting, reducing friction and improving cutting efficiency. Loosen the blade holder 3 by rotating the adjusting handwheel 15, and slide the blade holder 3 onto the scale rod 2. The specific scale position is then adjusted, and the adjusting handwheel 15 is tightened to abut against the ruler rod 2 to ensure cutting accuracy. The anti-collision pad 16 installed on the blade holder 3 acts as a buffer during the cutting process, preventing the blade holder 3 from directly colliding with the object being cut or other hard objects, and protecting the equipment from damage. The fixed rod 1 and the ruler rod 2 are pushed to move the entire cutting pusher along the cutting direction. The blade head 4 slides synchronously under the drive of the blade holder 3 to cut the item. After the cutting is completed, the fastener 8 is loosened to release the fixed connection between the fixed rod 1 and the ruler rod 2. The ruler rod 2 is folded back to a position parallel to the fixed rod 1 through the insert 7 to obtain a strip-shaped cutting pusher, which is easy to store and carry. During the folding process, the second spring 18 generates a downward pushing force to ensure that the fixed rod 1 and the ruler rod 2 are in contact.

[0025] Example 2

[0026] Please see Figures 3-5This utility model provides an embodiment of a foldable and retractable T-shaped cutting pusher. The difference from embodiment 1 is that the upper end of the fixed rod 1 is provided with a locking component for restricting the movement of the ruler rod 2. The locking component includes a fixed locking block 141 and a locking seat 142 fixedly connected to the left and right recesses on the upper end of the fixed rod 1. Several first springs 143 are installed in the upper opening of the locking seat 142, and a locking limit block 144 is fixedly connected to the upper end of the first springs 143.

[0027] During operation, loosen the fastener 8 to remove it from the locking hole 11, press the locking limit block 144 inward, compress the first spring 143, and fully engage the locking limit block 144 without affecting the rotation of the ruler rod 2. Rotate the ruler rod 2 via the insert 7, separating the first magnet 12 and the second magnet 13. The ruler rod 2 and the fixing rod 1 unfold from their folded state to a mutually perpendicular position. Secure the fixing rod 1 and the ruler rod 2 together using the fastener 8 to prevent accidental rotation or loosening during cutting. Place the second pulley group 6 on the side of the fixing rod 1 against the side of the object being cut, serving as a guide and positioning reference. Simultaneously, place the first pulley group 5 on the surface of the object being cut. Utilize the rolling characteristics of the pulley group to ensure smooth sliding of the cutting pusher during cutting, reducing friction and improving cutting efficiency. Loosen the knife holder 3 by rotating the adjusting handwheel 15, and slide the knife holder 3 to the specific position on the ruler rod 2. Adjust the scale position and then tighten the adjusting handwheel 15 to abut against the ruler rod 2 to ensure cutting accuracy. The anti-collision pad 16 installed on the blade holder 3 acts as a buffer during the cutting process to prevent the blade holder 3 from directly colliding with the object being cut or other hard objects, protecting the equipment from damage. Push the fixed rod 1 and the ruler rod 2 to move the entire cutting pusher along the cutting direction. The blade head 4 slides synchronously under the drive of the blade holder 3 to cut the item. After cutting, loosen the fastener 8 to release the fixed connection between the fixed rod 1 and the ruler rod 2. Fold the ruler rod 2 back to a position parallel to the fixed rod 1 through the insert 7. The fixed locking block 141 limits one side of the ruler rod 2. Under the rebound force of the first spring 143, push the locking limit block 144 upward to limit the other side of the ruler rod 2, resulting in a strip-shaped cutting pusher, which is easy to store and carry. During the folding process, the second spring 18 generates a downward pushing force to ensure that the fixed rod 1 and the ruler rod 2 are in contact.

[0028] Through the above steps, the design of the fixed rod 1 and the ruler rod 2 being foldably and rotatably connected by the insert 7 allows the pusher to be easily folded and stored when not in use, greatly reducing its size and weight, making it easy to carry and transport. Secondly, by using the sliding blade holder 3 sleeved on the outside of the ruler rod 2, users can adjust the position of the blade holder 3 as needed to achieve precise cutting of materials of different lengths, no longer limited by the size of the equipment itself. In addition, the second pulley group 6 with a 15° inclination on the side of the fixed rod 1 and the first pulley group 5 vertically installed at the top and bottom ensure smooth sliding and accurate positioning during the cutting process, improving cutting quality and efficiency. It is not only portable and easy to use, but also adaptable to cutting needs of different lengths, bringing greater convenience and efficiency to cutting operations. This solves the problem that existing cutting pushers rely on fasteners for connection, which is not convenient for disassembly, transportation, or storage, and requires a large operating space.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
