Description

Technical Field

[0001] This invention relates to hardware cutting technology, specifically a portable hardware processing fixed-depth cutting device. Background Technology

[0002] As is well known, in on-site operations such as hardware processing, equipment maintenance, and building installation, it is often necessary to quickly cut small metal workpieces such as bolts, pipe fittings, and angle irons. Due to the complex working environment and lack of a fixed workbench, portable manual or electric cutting tools are the preferred choice. These devices typically require a lightweight structure, flexible operation, and a certain degree of cutting precision control to meet the dual requirements of efficiency and safety on-site.

[0003] The shortcomings of existing technologies lie in the fact that current portable cutting tools generally suffer from limited functionality: most only have a cutting function and rely on external clamps to hold the workpiece, which can easily lead to off-center cutting or safety accidents due to loosening; while some devices with integrated clamping structures can hold the workpiece, they cannot precisely control the cutting depth and still require estimation by measuring tape or visual estimation, affecting processing consistency. Furthermore, existing products have complex adjustment mechanisms, non-adjustable clamping force, difficulty in adapting to hardware of different sizes, and lack a reliable self-locking mechanism, making them prone to loosening in vibrating environments. Therefore, there is an urgent need for a portable device that integrates reliable clamping, precise depth control, and convenient cutting to overcome these shortcomings. Summary of the Invention

The adjustment mechanism is driven by a retaining plate located inside the adjustment block. After the retaining plate is threadedly engaged with the multi-section screw at the corresponding position, the restriction between the multi-section screw and the inner rod is passively released. One set of multi-section screws connected to the retaining plate inside the adjustment block is rotatably fixed to the adjustment block, while the remaining sets of multi-section screws can rotate, causing the telescopic column threaded to the top of the multi-section screw to slide up and down.

[0010] As a further description of the above technical solution: the adjusting screw teeth are set in the inner wall of the slot for threaded insertion of multiple screw sections in the telescopic column, the telescopic column movably passes through the bearing seat and is inserted into the middle of the clamping end of the clamping seat, and a cutting seat is fixedly connected to one end of the telescopic column inserted into the clamping end of the clamping seat.

[0011] As a further description of the above technical solution: the shape and size of the abutting screw teeth are adapted to the thread groove.

[0012] As a further description of the above technical solution: the width of the adjusting screw teeth is adapted to the thread groove, and the depth is shallower than the depth of the thread groove.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-7 This invention provides a portable hardware parts processing depth-fixed cutting device technical solution: including: a clamping base 1, with a bearing seat 9 arranged between two sets of clamping bases 1 to form an X shape, the two sets of clamping bases 1 being divided into two parts by the bearing seat 9, one part being a clamping end and the other part being a hand-held end; further including: Adjusting block 8 is connected to the inside of the handheld end of clamp 1 via two sets of support rods 5; The multi-section screw 7 is movably inserted into the adjusting block 8; Inner rod 6 is inserted into multi-section screw rod 7; An adjustment mechanism is located at the connection between the adjustment block 8, the multi-section screw 7, and the inner rod 6. The adjustment mechanism is connected to a locking plate 12 inside the adjustment block 8. After the locking plate 12 and the corresponding multi-section screw 7 are threadedly engaged, the restriction between the multi-section screw 7 and the inner rod 6 is passively released. One set of multi-section screws 7 connected to the locking plate 12 inside the adjustment block 8 is rotatably fixed to the adjustment block 8, while the remaining sets of multi-section screws 7 can rotate, causing the telescopic column 3 threadedly connected to the top of the multi-section screw 7 to slide up and down.

[0025] When cutting hardware fittings, in situations with many limitations, a portable hardware cutting device is necessary. When using this portable device, after removing the hardware, place it on the clamping end of the clamping base 1. Use the auxiliary clamping wheels 2 on the inner side of the clamping end to clamp and secure the hardware. Then, grasp the pressing rods 13 on both sides of the adjusting block 8 on the inner side of the hand-held end of the clamping base 1, and combine them with the attached... Figure 3 and 4As shown, when the pressing rod 13 is pressed inward, it causes the two sets of movable frames 15 stacked on top of each other to slide relative to each other. This causes the symmetrically arranged locking plates 12 on both sides of the movable slot 25 in the adjusting block 8 to retract into the adjusting block 8, thus separating the locking plates 12 from the multi-section screws 7 inserted in the movable slot 25. At this time, the adjusting block 8 can be moved from the hand end of the clamping seat 1 to the clamping end. At this time, the two sets of support rods 5 connected to both sides of the adjusting block 8 by the rotating shaft 14 also expand the included angle on the inner side. Figure 1 As shown, since one end of the two sets of support rods 5 is connected to both ends of the adjusting block 8, and the other end of the two sets of support rods 5 is rotatably connected to the top of the folding groove 4 opened on the inner side of the hand-held end of the clamping seat 1, as the adjusting block 8 slides upward, the angle of the two sets of support rods 5 that were originally tilted downward with a small angle is gradually expanded, thereby expanding the distance between the two hand-held ends of the clamping seat 1. By using the principle of lever, the distance between the two clamping ends of the clamping seat 1 is gradually reduced, thereby using the clamping end of the clamping seat 1 in conjunction with the auxiliary clamping wheel 2 to clamp and fix the hardware. In another embodiment of the present invention, preferably, the inner side of the hand-held end of the two sets of clamps 1 is provided with a folding groove 4, the top end of the folding groove 4 is rotatably connected to one end of the support rod 5 through a rotating shaft 14, the other end of the support rod 5 is rotatably connected to both ends of the adjusting block 8 through the rotating shaft 14, and a movable groove 25 is provided in the center of the adjusting block 8, and multiple sections of screw 7 are inserted into the movable groove 25.

[0026] In another embodiment of the present invention, pressing rods 13 are slidably inserted into the other two ends of the adjusting block 8 that are misaligned with the rotating shaft 14. The bottom end of the pressing rod 13 is movably inserted into the adjusting block 8 and fixedly connected to two sets of movable frames 15 respectively. The two sets of movable frames 15 are installed in the adjusting block 8 in a stacked manner, and the ends of the two sets of movable frames 15 away from the pressing rod 13 are connected to the inner side wall of the adjusting block 8 through a return spring 16.

[0027] In another embodiment of the present invention, two sets of movable frames 15 are provided with a card plate 12 on their inner sides. The card plate 12 is symmetrically and movablely inserted into the two side walls of the movable slot 25, and a single set of abutting screw teeth 23 is provided on the inner side of the card plate 12.

[0028] After the hardware is securely clamped at the clamping end of the clamping seat 1, the pressing rods 13 on both sides of the adjusting block 8 are released. The return spring 16 connected between the end of the movable frame 15 away from the pressing rod 13 and the inner wall of the adjusting block 8 rebounds, thereby resetting the two sets of movable frames 15. This allows the card plates 12, which are movably inserted into the movable slot 25 on both sides, to be reinserted into the movable slot 25. The card plates 12 are then reconnected to the surface of the multi-section screw 7 inserted into the movable slot 25. By utilizing the meshing of the threaded connection between the multi-section screw 7 and the card plate 12, the position between the adjusting block 8 and the multi-section screw 7 is fixed, and the position and angle of the two sets of support rods 5 are limited, ultimately maintaining the clamping force of the clamping end of the clamping seat 1 on the hardware. In another embodiment of the present invention, the adjustment mechanism includes a threaded groove 22 formed on the surface of the multi-section screw 7. One end of a limiting ball 21 is inserted into the bottom of the threaded groove 22, and the other end of the limiting ball 21 is inserted into the limiting grooves 19 formed on both sides of the surface of the inner rod 6. A limiting spring 20 is connected to the bottom of the limiting ball 21 and the limiting groove 19. The threaded groove 22 is threadedly connected with abutting screw teeth 23 and adjusting screw teeth 24.

[0029] In another embodiment of the present invention, the adjusting screw 24 is provided in the inner wall of the slot of the telescopic column 3 for threaded insertion of the multi-section screw 7. The telescopic column 3 movably passes through the bearing seat 9 and is inserted into the middle of the clamping end of the clamping seat 1. The end of the telescopic column 3 inserted into the clamping end of the clamping seat 1 is fixedly connected to the cutting seat 11.

[0030] Combined with appendix Figure 5 and 6 As shown, when the locking plate 12 inside the adjusting block 8 is threadedly engaged with the surface of the multi-section screw 7 at the corresponding position, rotating the inner rod 6 will cause the other multi-section screws 7, except those threadedly engaged with the locking plate 12, to rotate with the inner rod 6. The top of the multi-section screw 7 is threadedly inserted into the telescopic column 3. The rotation of the multi-section screw 7 will cause the telescopic column 3 threadedly connected to its top to slide up and down, thereby displacing the cutting seat 11 connected to the top of the telescopic column 3 up and down. This will bring the high-speed rotating cutting blade installed in the cutting seat 11 closer to the hardware clamped and fixed at the clamping end of the clamping seat 1. The cutting blade can be used to cut the clamped hardware by moving it close or far away. In addition, the scale 10 on the surface of the telescopic column 3 can be used to control the cutting depth of the hardware. The specific depth control operation is as follows: after clamping the hardware, first put the stopped cutting blade close to the cutting surface of the hardware, observe the scale 10, and separate the cutting blade from the hardware before starting the cutting blade to facilitate the start of the cutting blade. After starting, according to the required cutting depth, observe the scale 10 and advance the cutting blade to the clamping end of the clamping seat 1 to the required depth. There are two specific limitations to achieving the above effect: Part 1: This part describes how the rotation of the inner rod 6 only drives the rotation of the remaining multi-section screws 7, but not the multi-section screws 7 that engage with the threaded part of the clamping plate 12. Specifically: (See attached...) Figure 6 and 7 As shown, the multi-section screw 7 is composed of multiple sets of screws with bearings at their connection points. An inner rod 6 is inserted inside the multi-section screw 7. Each set of screws has only one thread on its surface, and the inner side of the clamping plate 12 also has only one thread tooth of the corresponding size. One end of an elliptical limiting ball 21, which is placed horizontally, is slidably inserted into the bottom of the threaded groove 22 on the surface of each set of multi-section screws 7. The other end of the limiting ball 21 is inserted into the limiting groove 19 on both sides of the inner rod 6 and connected to the limiting spring 20. The inner side of the clamping plate 12 is provided with abutting screw teeth 23. The shape and size of the abutting screw teeth 23 are adapted to the threaded groove 22. When the abutting screw teeth 23 are threadedly connected in the threaded groove 22, the abutting screw teeth 23 will squeeze the limiting ball 21, squeeze the limiting ball 21 out of the threaded groove 22 and squeeze the limiting spring 20 and insert it into the folding groove 4 on the outside of the inner rod 6. At this time, the multi-section screw 7 loses the locking restriction of the limiting ball 21 between it and the inner rod 6, while each section of the other multi-section screw 7 has the locking restriction of the limiting ball 21 between it and the inner rod 6. Therefore, when the inner rod 6 rotates, the multi-section screw 7 that is threadedly engaged with the clamping plate 12 will not rotate with the inner rod 6, while the other sections of the multi-section screw 7 will rotate with the inner rod 6. The multi-section screw 7 forms a bearing for rotational connection between the clamping plate 12, the adjusting block 8 and the multi-section screw 7, and can maintain a fixed position while rotating. Part Two: This part describes how a multi-section screw rod 7 is threaded into the telescopic column 3. One end of the screw rod 7 can drive the telescopic column 3 to move up and down by rotating. Specifically, it is described in conjunction with the attached... Figure 7 As shown, the adjustment screw 24 is threaded between the inner side of the telescopic column 3 and the multi-section screw 7. The width of the adjustment screw 24 is adapted to the thread groove 22, but the depth of the adjustment screw 24 is small. The depth of the adjustment screw 24 inserted into the thread groove 22 cannot reach the limiting ball 21 set in the thread groove 22. Therefore, even if the adjustment screw 24 on the inner side of the telescopic column 3 is threaded into the thread groove 22 of the multi-section screw 7, it will not affect the limiting connection between the multi-section screw 7 and the inner rod 6. In another embodiment of the present invention, the shape and size of the abutting screw teeth 23 are adapted to the threaded groove 22.

[0031] In another embodiment of the present invention, the width of the adjusting screw tooth 24 is adapted to the thread groove 22, and the depth is shallower than the depth of the thread groove 22.

[0032] In another embodiment of the present invention, auxiliary clamping wheels 2 for clamping auxiliary hardware are provided on the inner side of the clamping ends of the two sets of clamping seats 1.

[0033] In another embodiment of the present invention, preferably, a scale 10 is provided on the surface of the telescopic column 3.

[0034] Therefore, when the inner rod 6 is rotated, the inner rod 6 can drive the multi-section screw 7 inserted in the telescopic column 3 to rotate, thereby causing the cutting seat 11 to move up and down. At the same time, the multi-section screw 7, which meshes with the inner clamping plate 12 of the adjusting block 8, transforms its own threaded connection into a function of limiting the position of the clamping plate 12 and the adjusting block 8.

[0035] It should also be noted that a micro motor is installed inside the cutting base 11 to drive and connect the cutting blade, enabling the cutting blade to be started and rotated quickly for cutting. The two sets of movable frames 15 stacked vertically within the adjusting block 8 are respectively provided with a locking strip 18 and a locking groove 17 at the connection point, so as to enable the two sets of movable frames 15 to maintain relative horizontal movement. The middle end of the clamp 1 is connected to the bearing seat 9, and the center of the bearing seat 9 is provided with a hole and groove whose size and shape are adapted to the telescopic column 3. The hole and groove have a certain damping effect with the telescopic column 3. The damping effect can be achieved by adapting the size, or by setting a rubber pad to increase friction on the inner side wall of the hole and groove. The folding groove 4 on the inner side wall of the hand-held end of the clamp 1 provides room for the adjustment of the angle of the two sets of support rods.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
