Description

Technical Field

[0001] The present invention relates to the technical field of glass cutting, and specifically to a glass breaking tool. Background Art

[0002] During the glass cutting process, after scribing with a glass cutter, depending on the positional relationship between the scribed line and the glass edge, pliers and three-point pliers are often used. When the scribed line is parallel to the glass edge, the pliers are used to clamp the glass and pry it in the opposite direction of the scribed side. Since the stress at the bottom of the notch increases after scribing with the glass cutter, the glass along the edge can be easily broken. When the scribed line is perpendicular to the glass edge, the convex point in the middle of the three-point pliers is aligned with the back of the scribed line, and the convex points on both sides are on the same side of the scribed line and distributed on both sides of the scribed line. The glass can be easily broken using the lever principle.

[0003] However, during glass cutting, cuts at different positions are required according to needs. Therefore, the workers cutting the glass need to frequently use pliers and glass pliers. Both are metal tools and are relatively heavy to carry around. Repeatedly picking them up will cause a lot of unnecessary walking, increasing the labor intensity of the workers cutting the glass. Secondly, when using the three-point pliers to break the glass longitudinally, it is necessary to pay special attention to which side of the glass the scribed line of the glass cutter is on. Only when the convex point in the middle of the three-point pliers is aligned with the back of the glass scribed line, and the convex points on both sides are on the same side as the scribed line and are located on both sides of the scribed line, can the glass be easily broken along the scribed line using the lever principle. Otherwise, the glass cannot be broken, or a very large force is required to break the glass. In such cases, the edge of the broken glass is uneven and may even break into pieces. Moreover, since the original glass sheet is transparent, after scribing and through operations such as handling and placement, it is not easy to distinguish which side of the glass the scribed line is on. When using the three-point pliers to break the glass, there is often a risk that the glass cannot be broken or the glass breaks into pieces, making it inconvenient to use.

[0004] As disclosed in the Chinese patent publication number: CN105366933B, a glass clamp includes a first handgrip rod, a second handgrip rod, a first connecting rod, a second connecting rod, a first clamp block and a second clamp block. The second handgrip rod extends towards the first handgrip rod to form a first extension block and a second extension block extending from the first extension block. The end of the first handgrip rod is pivotally connected to the first extension block; the first connecting rod is pivotally connected to the second handgrip rod, with its first end extending out of the second handgrip rod and its second end extending into the second handgrip rod; the second connecting rod is located between the first handgrip rod and the second handgrip rod, with its first end pivotally connected to the second end of the first connecting rod and its second end pivotally connected to the first handgrip rod; the first clamp block is installed at the first end of the first connecting rod and has a first clamping part; the second clamp block is installed on the second extension block and has a second clamping part; when the operator presses the first handgrip rod and the second handgrip rod to move closer to each other, the first clamping part and the second clamping part are driven by the first connecting rod and the second connecting rod to clamp the glass plate together, increasing stability and being more labor-saving. However, when clamping the glass plate, attention should be paid to placing the pressing nails on the second clamping part and the pressing nails on the first clamping part according to the position of the glass cutter's scribed line. If the pressing nails on the second clamping part and the scribed line are on the same side of the glass, it is impossible to break the glass more labor-savingly, and even easily cause the glass to break. Summary of the Invention

[0005] The technical problems to be solved by the present invention are how to reduce the labor intensity of glass trimming workers, reduce the number of tools to be carried, and how to avoid distinguishing the front and back sides according to the glass cutter's scribed line when using a three-point clamp. Opposite clamping directions of the three-point clamp are likely to cause the glass to break. The purpose of the present invention is to provide a multifunctional glass breaking clamp with functions of lateral edge breaking, longitudinal glass breaking, no need to distinguish the front and back sides, and convenient to carry.

[0006] The technical solution adopted by the present invention is: a portable multifunctional glass breaking clamp, including a breaking clamp, which is composed of a middle hinge connection between a first clamp body and a second clamp body. The breaking clamp is divided into a hand-held part and a clamping part through the hinge connection. It also includes a connecting head. Prismatic plug connectors are provided at the ends of the clamping parts of the first clamp body and the second clamp body. The connecting head includes a first plug interface, a second plug interface, a fixed seat and a movable seat. The fixed seat and the movable seat are slidably connected through a strip-shaped movable groove. A plurality of cylinders are provided on the side walls of the fixed seat and the movable seat away from the breaking clamp. The first plug interface is fixedly connected to the fixed seat. The second plug interface is movably connected to the top of the movable seat through an adjustment mechanism. The middle of the movable seat is movably connected to the first plug interface through a connecting mechanism. The first plug interface and the second plug interface are respectively inserted into the prismatic plug connectors at the ends of the first clamp body and the second clamp body.

[0007] Using the portable multifunctional glass breaking clamp provided by the present invention can obtain the following beneficial effects:

[0008] (1) By combining the glass breaking pliers with the connector, the glass can be longitudinally broken using the lever principle. When the connector is removed, the pliers can be used as ordinary pliers for lateral edge breaking.

[0009] (2) Taking the quadrangular prism socket at the end of the pliers as the vertex and aligning it with the other side of the surface scratched by the glass cutter, the wide quadrangular prism socket can smoothly break the glass along the scratched line. After connecting the connector, the pliers are changed into a three-point pliers, and the glass is broken along the longitudinal scratched line using the lever principle. One tool can break both laterally and longitudinally, facilitating the cutting of the glass sheet into appropriate sizes, reducing the number and weight of tools that glass cutting workers need to carry, avoiding a lot of unnecessary walking, and reducing the workload and labor intensity of the workers.

[0010] (3) By setting multiple cylinders on the fixed seat and the movable seat, and the movable seat is slidably connected to the fixed seat. By changing the positions of the cylinders on the movable seat, the traditional one-way breaking three-point pliers are changed into a two-way breaking one. No matter which side the glass cutter scratches, the breaking operation can be carried out, avoiding the problem that when the protrusion in the middle of the traditional three-point pliers is at the scratched line, the glass cannot be smoothly broken and the up and down clamping directions of the three-point pliers need to be changed, resulting in an extended working time and an increased labor amount of the workers.

[0011] Preferably, positioning grooves are provided on one side of the side wall of the quadrangular prism socket away from the hinge joint of the first pliers body and the second pliers body, and the positioning grooves are hemispherical; positioning columns and return springs are provided inside the side walls of the first socket and the second socket away from each other. One end of the two positioning columns protrudes from the side walls of the first socket and the second socket, and the protruding part is hemispherical. The protruding part on the positioning column is adapted to the shape and depth of the positioning groove.

[0012] By inserting the quadrangular prism sockets at the ends of the first pliers body and the second pliers body on the pliers into the first socket and the second socket on the connector respectively, and fixing them by the positioning columns being properly abutted against the positioning grooves to prevent detachment, the pliers for laterally breaking the glass can be modified into a three-point pliers for longitudinally breaking the glass. The connection is convenient, the stability of the connection is not affected during use, and it can be easily removed after use. The modification is convenient, there is no need to carry two sets of tools at the same time during the work process, it is easy to use, and the workload of the staff is reduced.

[0013] Preferably, the movable groove is provided in the middle of the fixed seat, and the movable seat is slidably connected to the middle of the fixed seat through the movable groove on the fixed seat.

[0014] The movable slot enables the movable seat to slide up and down in the middle of the fixed seat. By changing the position of the cylinder on the movable seat, the position of the cylinder in contact with the glass when longitudinally breaking the glass is changed, so that the cylinder can abut against the other side of the scribed line on the upper surface of the glass from bottom to top to break the glass upward, or the cylinder can abut against the other side of the scribed line on the lower surface of the glass from top to bottom to break the glass downward.

[0015] Preferably, at least four cylinders are provided on the fixed seat, and the four cylinders on the fixed seat are arranged in a quadrilateral distribution; at least two cylinders are provided on the movable seat, and the two cylinders on the movable seat are both arranged in the middle of the four cylinders on the movable seat, and the arrangement direction of the two cylinders on the movable seat is the same as the direction of the movable slot.

[0016] Place the glass to be cut horizontally in the middle position among the four cylinders on the fixed seat, and place the two cylinders on the movable seat on the upper and lower sides of the glass to be cut. When the movable seat moves upward, three cylinders for breaking the glass are formed by the cylinders at the lower part of the movable seat and the two cylinders at the upper side of the fixed seat, so as to break the glass upward; when the movable seat moves downward, three cylinders for breaking the glass are formed by the cylinders at the upper part of the movable seat and the two cylinders at the lower part of the fixed seat, so as to break the glass downward. It realizes that when the position of the movable seat is changed, the glass can be broken from top to bottom and from bottom to top, solving the problem that the protrusion in the middle of the traditional three-point clamp cannot break the glass when on one side of the scribed line, and it is necessary to reverse the up and down positions of the three-point clamp, which is inconvenient to use and wastes time.

[0017] Preferably, the distance between the two cylinders on the upper side of the fixed seat and the two cylinders on the lower side is greater than the thickness of the glass to be cut; the distance between the two cylinders on the movable seat is greater than the distance between the two cylinders on the upper side and the two cylinders on the lower side of the fixed seat.

[0018] The distance between the two cylinders on the upper side and the two cylinders on the lower side of the fixed seat is greater than the thickness of the glass to be cut, which is convenient for putting in glasses of different thicknesses. The distance between the two cylinders on the movable seat is greater than the distance between the two cylinders on the upper side and the two cylinders on the lower side of the fixed seat, which is convenient for increasing the moving distance of the movable seat, thereby increasing the impact force when the cylinder on the movable seat hits the glass, and facilitating the longitudinal breaking of the glass faster and more labor-saving.

[0019] Preferably, the adjusting mechanism includes a connecting rod, a sliding groove and a support rod. There are two connecting rods which are fixedly connected to the second socket on both sides of the second socket. The sliding groove is arranged on the connecting rod, and the support rod is fixedly connected to the movable seat. The two ends of the movable seat protrude from the two ends of the movable seat and are arranged in the sliding groove.

[0020] The adjustment mechanism facilitates adjusting the position of the movable seat through the second pliers body. Meanwhile, when the position of the movable seat is changed through the sliding groove, the second pliers body can always be connected to the connecting rod, preventing the problem that the position of the movable seat cannot be adjusted continuously due to interference after movement or displacement.

[0021] Preferably, the connecting mechanism includes a connecting rod and a connecting shaft. One end of the connecting rod is rotatably connected to the middle of the movable seat. A strip-shaped limiting groove is provided on the connecting rod, and a compression spring is provided in the limiting groove. Both ends of the connecting shaft are fixedly connected to the first insertion interface, the middle of the connecting shaft is arranged in the limiting groove and is slidably connected to the limiting groove, and the connecting shaft is far from the middle of the connecting rod in the limiting groove. Both ends of the compression spring are abutted against the connecting shaft and the inner wall of the limiting groove respectively.

[0022] Through the connecting rod and the compression spring inside the connecting rod, the movable seat is always pushed by the compression spring to the upper and lower ends of the fixed seat, and the force for breaking the glass is controlled by the pressure of the compression spring. After putting the glass to be broken in, change the position of the movable seat to make the movable seat move to the other end. During the movement, the cylinder on the movable column impacts the glass scribing line under the action of the force of the compression spring. When hitting the back of the scribing line, under the action of the lever principle and the increased stress at the bottom of the scribing line, the glass can be easily broken by the elastic force of the compression spring. When hitting one side of the scribing line, the glass is not easy to break, then there is no need to remove the pliers and turn the direction. By changing the position of the movable seat through the second pliers body, the glass can be easily broken from the opposite direction by using the lever principle through the relative position change between the fixed seat and the cylinder on the movable seat.

[0023] Preferably, the length of the hand-held part of the second pliers body on the pliers is shorter than the length of the hand-held part of the first pliers body. A glass cutter is provided at the end of the hand-held part of the first pliers body, and a rotating ring rotatably connected around the first pliers body is provided at the position flush with the end of the first pliers body on the hand-held part of the second pliers body.

[0024] By installing a rod-shaped glass cutter at the end of the second pliers body with a shorter length and installing a rotating ring in the middle of the second pliers body with a longer length, and placing the rotating ring on the edge of the glass to be scribed, the glass sheet can be scribed along the straight edge of the glass by using the glass cutter, realizing convenient cutting of the glass.

[0025] Preferably, a limiting stud is provided near the hinge of the hand-held part of the first pliers body. The limiting stud passes through the first pliers body and points to the second pliers body. The limiting stud is threadedly connected to the first pliers body, and the end of the limiting stud pointing to the second pliers body protrudes outside the first pliers body.

[0026] The distance between the first jaw body and the second jaw body at the handheld part can be limited by a limit stud, so as to limit the distance between the clamping parts of the breaking pliers. When performing a horizontal break, the handheld part can be firmly held, preventing the angle change of the clamping parts from causing displacement or tilt of the breaking pliers when breaking the glass, thereby damaging the glass. At the same time, when using the glass cutter at the end of the second jaw body for scribing and cutting, the distance between the first jaw body and the second jaw body can also be limited, so that the glass cutter will not shift during scribing and cutting.

[0027] Preferably, the width of the clamping part of the breaking pliers is greater than the width of the handheld part, and the opposite surfaces of the first jaw body and the second jaw body on the clamping part are both flat surfaces.

[0028] By increasing the width of the clamping part, it is more conducive to evenly dispersing the applied force when using the breaking pliers for horizontal breaking, providing a greater lever effect, making the breaking force more concentrated and effective. The opposite surfaces of the first jaw body and the second jaw body on the clamping part are both flat surfaces, which can facilitate the installation and fixing of the connecting head through other surfaces without affecting the function of the jaw bodies of the breaking pliers, so that it can be modified into a three-point pliers that does not need to distinguish between the upper and lower surfaces by installing the connecting head when needed.

[0049] Embodiment 1: A portable multi-functional glass breaking pliers

[0050] The following is further described in conjunction with specific embodiments. Refer to Figure 1-16As shown in the figure, this embodiment is a portable multi-functional glass breaking pliers, including a breaking pliers 1. The breaking pliers 1 is composed of a first pliers body 11 and a second pliers body 12 hinged in the middle. Through the hinge, the breaking pliers 1 is divided into a hand-held part and a clamping part. At the ends of the clamping parts of the first pliers body 11 and the second pliers body 12, there are provided quadrangular prism plug connectors 13. It also includes a connecting head 2. The connecting head 2 includes a first socket 21, a second socket 22, a fixed seat 23 and a movable seat 24. The fixed seat 23 and the movable seat 24 are slidably connected through a strip-shaped movable groove 25. On the side walls of the fixed seat 23 and the movable seat 24 away from the breaking pliers 1, there are provided a plurality of cylinders 26. The first socket 21 is fixedly connected to the fixed seat 23, and the second socket 22 is movably connected to the top of the movable seat 24 through an adjusting mechanism 28. The cross-sectional shapes of the quadrangular prism plug connectors 13 are adapted to the inner side walls of the first socket 21 and the second socket 22. The middle part of the movable seat 24 is movably connected to the first socket 21 through a connecting mechanism 29. The first socket 21 and the second socket 22 are respectively inserted into the quadrangular prism plug connectors 13 at the ends of the first pliers body 11 and the second pliers body 12. By combining the glass breaking pliers 1 with the connecting head 2, when the connecting head 2 is removed, the breaking pliers 1 can be used as an ordinary breaking pliers 1 for horizontal edge breaking; taking the quadrangular prism plug connector 13 at the end of the breaking pliers 1 as the vertex and aligning it with the other side where the surface has been scratched by the glass cutter 16, the wide quadrangular prism plug connector 13 can smoothly break the glass along the scored line; after connecting the connecting head 2, the breaking pliers 1 is changed into a three-point pliers, and the glass is broken along the longitudinal scored line by using the lever principle. One tool can break both horizontally and vertically, which is convenient for cutting the glass sheet into a suitable size, reducing the number and weight of tools that glass cutting workers need to carry, avoiding a lot of unnecessary walking, and reducing the workload and labor intensity of workers; by providing a plurality of cylinders 26 on the fixed seat 23 and the movable seat 24, the movable seat 24 is slidably connected to the fixed seat 23. By changing the positions of the cylinders 26 on the movable seat 24, the traditional one-way breaking three-point pliers is changed into a two-way breaking one. No matter which side the glass cutter 16 scores, the breaking operation can be carried out, avoiding the problem that when the protrusion in the middle of the traditional three-point pliers is at the scored line, the glass cannot be smoothly broken and the direction of the three-point pliers needs to be changed, resulting in an extended working time and an increased labor amount of workers.

[0051] Refer to Figure 4 , Figure 7 , Figure 14 or Figure 15As shown in any of the accompanying drawings, in this embodiment, positioning grooves 14 are provided on the side walls of the quadrangular prism plug connector 13 away from the hinge joints of the first pliers body 11 and the second pliers body 12, and the positioning grooves 14 are hemispherical; positioning posts 27 and return springs 271 are provided inside the side walls of the first socket 21 and the second socket 22 away from each other. One end of each of the two positioning posts 27 protrudes from the side walls of the first socket 21 and the second socket 22, and the protruding part is hemispherical. The protruding part on the positioning post 27 is adapted to the shape and depth of the positioning groove 14. By inserting the quadrangular prism plug connectors 13 at the ends of the first pliers body 11 and the second pliers body 12 on the pliers 1 into the first socket 21 and the second socket 22 on the connector 2 respectively, and fixing them by the positioning post 27 being properly abutted against the positioning groove 14 to prevent detachment, the pliers 1 for horizontally breaking glass can be modified into a three-point pliers for longitudinally breaking glass. The connection is convenient, the connection stability is not affected during use, and it can be easily removed after use. The modification is convenient, there is no need to carry two sets of tools simultaneously during the work process, it is easy to use, and the workload of the staff is reduced.

[0052] Referring to Figure 12 As shown, in this embodiment, the movable groove 25 is provided in the middle of the fixed seat 23, and the movable seat 24 is slidably connected to the middle of the fixed seat 23 through the movable groove 25. On the fixed seat 23, the movable groove 25 enables the movable seat 24 to slide up and down in the middle of the fixed seat 23. By changing the position of the cylinder 26 on the movable seat 24, the position of the cylinder 26 in contact with the glass during longitudinal glass breaking is changed, so that the cylinder 26 can abut against the other side of the scribed line on the upper surface of the glass from bottom to top to break the glass upward, or the cylinder 26 can abut against the other side of the scribed line on the lower surface of the glass from top to bottom to break the glass downward.

[0053] Referring to Figure 5 、 Figure 8As shown in any of the attached drawings, in this embodiment, at least four cylinders 26 are provided on the fixed seat 23, and the four cylinders 26 on the fixed seat 23 are arranged in a quadrilateral pattern; at least two cylinders 26 are provided on the movable seat 24, and the two cylinders 26 on the movable seat 24 are both arranged in the middle of the four cylinders 26 on the movable seat 24, and the arrangement direction of each cylinder 26 on the movable seat 24 is the same as the direction of the movable slot 25. Place the glass to be cut horizontally at the position in the middle of the four cylinders 26 on the fixed seat 23, and place the two cylinders 26 on the movable seat 24 on the upper and lower sides of the glass to be cut. When the movable seat 24 moves upward, three cylinders 26 for breaking the glass are formed by the cylinders 26 at the lower part of the movable seat 24 and the two cylinders 26 on the upper side of the fixed seat 23, so as to break the glass upward; when the movable seat 24 moves downward, three cylinders 26 for breaking the glass are formed by the cylinders 26 at the upper part of the movable seat 24 and the two cylinders 26 on the lower side of the fixed seat 23, so as to break the glass downward. It is realized that when the position of the movable seat 24 is changed, the glass can be broken from top to bottom and from bottom to top, solving the problem that the convex part in the middle of the traditional three-point clamp cannot break the glass when it is on one side of the scribed line, and it is necessary to reverse the up and down positions of the three-point clamp, which is inconvenient to use and wastes time.

[0054] Refer to Figure 5 or Figure 8 As shown, in this embodiment, the distance between the two cylinders 26 on the upper side of the fixed seat 23 and the two cylinders 26 on the lower side is greater than the thickness of the glass to be cut; the distance between the two cylinders 26 on the movable seat 24 is greater than the distance between the two cylinders 26 on the upper side of the fixed seat 23 and the two cylinders 26 on the lower side. The distance between the two cylinders 26 on the upper side of the fixed seat 23 and the two cylinders 26 on the lower side is greater than the thickness of the glass to be cut, which is convenient for placing glasses of different thicknesses. The distance between the two cylinders 26 on the movable seat 24 is greater than the distance between the two cylinders 26 on the upper side of the fixed seat 23 and the two cylinders 26 on the lower side, increasing the moving distance of the movable seat 24, thereby increasing the impact force when the cylinders 26 on the movable seat 24 impact the glass, and facilitating the longitudinal breaking of the glass faster and more labor-saving.

[0055] Refer to Figure 4 or Figure 13As shown, in this embodiment, the adjustment mechanism 28 includes a connecting rod 281, a sliding groove 282, and a support rod 283. There are two connecting rods 281, which are fixedly connected to the second insertion port 22 on both sides of the second insertion port 22. The sliding groove 282 is arranged on the connecting rod 281. The support rod 283 is fixedly connected to the movable seat 24. Both ends of the movable seat 24 protrude from both ends of the movable seat 24 and are arranged in the sliding groove 282. The adjustment mechanism 28 facilitates adjusting the position of the movable seat 24 through the second pliers body 12. At the same time, when the position of the movable seat 24 changes through the sliding groove, the second pliers body 12 can always be connected to the connecting rod 281, preventing the problem that the position of the movable seat 24 cannot be adjusted continuously due to interference after movement or displacement.

[0056] Refer to Figure 4 or Figure 15 As shown, in this embodiment, the connection mechanism 29 includes a connecting rod 291 and a connecting shaft 294. One end of the connecting rod 291 is rotatably connected to the middle of the movable seat 24. A strip-shaped limiting groove 292 is arranged on the connecting rod 291, and a compression spring 293 is arranged in the limiting groove 292. Both ends of the connecting shaft 294 are fixedly connected to the first insertion port 21. The middle of the connecting shaft 294 is arranged in the limiting groove 292 and is slidably connected to the limiting groove 292. And the connecting shaft 294 is far from the middle of the connecting rod 291 in the limiting groove 292. Both ends of the compression spring 293 are respectively abutted against the connecting shaft 294 and the inner wall of the limiting groove 292. Through the connecting rod 291 and the compression spring 293 in the connecting rod 291, the movable seat 24 is always pushed by the compression spring 293 to the upper and lower ends of the fixed seat 23, and the force for breaking the glass is controlled by the pressure of the compression spring 293. After putting the glass to be broken, the position of the movable seat 24 is changed, so that the movable seat 24 moves to the other end. During the movement, the cylinder 26 on the movable column impacts the glass scribing position under the action of the force of the compression spring 293. When hitting the back of the scribing position, under the action of the lever principle and the increase of the bottom stress at the scribing position, the glass can be easily broken by the elastic force of the compression spring 293. When hitting one side of the scribing position, the glass is not easy to break. Then, there is no need to remove the breaking pliers 1 and turn it around. By changing the position of the movable seat 24 through the second pliers body 12, the glass can be easily broken from the opposite direction by changing the relative positions of the cylinder 26 on the fixed seat 23 and the movable seat 24 by using the lever principle.

[0057] Refer to Figure 9 or Figure 11As shown, in this embodiment, the length of the holding part of the second pliers body 12 on the pliers 1 is shorter than that of the holding part of the first pliers body 11. A glass cutter 16 is provided at the end of the holding part of the first pliers body 11. A rotating ring 15 rotatably connected around the first pliers body 11 is provided at the position on the holding part of the second pliers body 12 that is flush with the end of the first pliers body 11. By providing the rod-shaped glass cutter 16 at the end of the second pliers body 12 with a shorter length and installing the rotating ring 15 in the middle of the second pliers body 12 with a longer length, and placing the rotating ring 15 on the edge of the glass to be scribed, the glass cutter 16 can be used to scribe the glass sheet along the straight edge of the glass, facilitating the cutting of the glass.

[0058] Referring to Figure 1-4 or Figure 6-7 or Figure 9-11 As shown in any of the attached drawings, in this embodiment, a limit stud 17 is provided near the hinge of the holding part of the first pliers body 11. The limit stud 17 passes through the first pliers body 11 and points to the second pliers body 12. The limit stud 17 is threadedly connected to the first pliers body 11. The end of the limit stud 17 pointing to the second pliers body 12 protrudes outside the first pliers body 11. The distance between the first pliers body 11 and the second pliers body 12 at the holding part can be limited by the limit stud 17, thereby limiting the distance between the clamping parts of the pliers 1. When performing a horizontal break, the holding part can be firmly held, avoiding displacement or tilt of the pliers 1 when breaking the glass due to a change in the angle of the clamping parts, which may cause damage to the glass. At the same time, the distance between the first pliers body 11 and the second pliers body 12 can also be limited when using the glass cutter 16 at the end of the second pliers body 12 for scribing and cutting, so that the glass cutter 16 will not shift during scribing and cutting.

[0059] Referring to Figure 10 As shown, in this embodiment, the width of the clamping part of the pliers 1 is greater than the width of the holding part, and the opposite surfaces of the first pliers body 11 and the second pliers body 12 on the clamping part are both flat surfaces. By increasing the width of the clamping part, it is more conducive to evenly dispersing the applied force when using the pliers 1 for horizontal breaking, providing a greater lever effect, making the breaking force more concentrated and effective. The opposite surfaces of the first pliers body 11 and the second pliers body 12 on the clamping part are both flat surfaces, which can facilitate the installation and fixed connection of the connecting head 2 through other surfaces without affecting the function of the pliers body, so that it can be modified into a three-point pliers that does not need to distinguish between the upper and lower surfaces when the connecting head 2 is installed when needed.

[0060] Embodiment 2, Method of Using the Pliers for Horizontally Cutting Glass

[0061] When it is necessary to break the glass horizontally, only use the breaking pliers 1. Make marks on the original glass sheet according to the required cutting size. Align the glass cutter 16 on the second pliers body 12 with the marked position. The upper and lower sides of the rotating ring 15 on the first pliers body 11 are stuck on the edge of the glass. Then rotate the limit screw 17 so that the protruding part of the limit screw 17 after protruding from the first pliers body 11 abuts against the second pliers body 12, so that the distance between the first pliers body 11 and the second pliers body 12 remains unchanged when grasping the handle part of the breaking pliers 1. Then, a score line parallel to the edge of the original glass sheet can be cut out along the edge of the glass.

[0062] When scoring the glass with the glass cutter 16, the glass cutter 16 will leave a groove with a very sharp bottom on the glass. Then align the flat mouth at the top of the breaking pliers 1 with the edge of the groove and clamp it, so that the surface of the glass with the groove is pressed downward and cracked. Since the bottom of the groove is narrow, there is a large stress concentration, and the brittle glass is very easy to crack along this groove, and the glass can be broken horizontally.

[0063] Example 3, the usage method of using a portable multi-functional glass breaking pliers to break the glass longitudinally

[0064] When it is necessary to break the glass longitudinally, connect the breaking pliers 1 with the connector 2. Insert the first socket 21 into the quadrangular prism socket 13 at the end of the first pliers body 11, and insert the second socket 22 into the quadrangular prism socket 13 at the end of the second pliers body 12. The return spring 271 behind the positioning post 27 enables the positioning post 27 to expand and contract during insertion. After the insertion is completed, the positioning post 27 can be reset and snapped into the positioning groove 14, so as to complete the fixation of the connector 2 and the breaking pliers 1 and prevent the connector 2 from accidentally falling off the breaking pliers 1. When breaking the glass with the longitudinal cutting line drawn, place the two cylinders 26 above and the two cylinders 26 below the fixed seat 23 on the upper and lower sides of the glass respectively. Then adjust the position of the movable seat 24 through the second pliers body 12 so that the distances from the two cylinders 26 on the movable seat 24 to the glass surface are equal, and move the two cylinders 26 on the movable seat 24 to both sides of the scoring line. Then loosen the second pliers body 12. After the movable seat 24 loses the pulling force of the second pliers body 12, under the action of the compressed spring 293 in the connecting rod 291, it is pushed along the movable groove 25 to the top or bottom of the fixed seat 23 and forms three upward or downward fulcrums respectively. Under the action of the compressed spring 293, the glass is broken by using the lever principle.

[0065] When the scoring line is located on the upper surface of the glass and the movable seat 24 moves to the top of the fixed seat 23, the cylinder 26 below the movable seat 24 pushes the glass upward, combined with the two cylinders 26 above the fixed seat 23 applying resistance to the glass on both sides of the scoring line, so that the stress at the bottom of the groove at the scoring line increases, and the glass can be easily broken by the thrust of the compressed spring 293;

[0066] When the scribed line is located on the lower surface of the glass and the movable seat 24 moves to the bottom end of the fixed seat 23, the cylinder 26 above the movable seat 24 pushes the glass downward. Combining with the two cylinders 26 below the fixed seat 23 applying resistance to the glass on both sides of the scribed line, the stress at the bottom of the groove of the scribed line is increased, and the glass can be easily broken by the thrust of the compression spring 293;

[0067] When the scribed line is located on the lower surface of the glass and the movable seat 24 moves to the top end of the fixed seat 23, the cylinder 26 below the movable seat 24 pushes the glass upward. However, since the scribed line is on the lower surface of the glass, the glass cannot be broken smoothly. At this time, there is no need to remove the connector 2. The position of the second clamp body 12 can be adjusted to move the movable seat 24 downward, and the glass can be easily broken by the cylinder 26 above the movable seat 24 and the two cylinders 26 below the fixed seat 23 at the scribed line through the lever principle;

[0068] When the scribed line is located on the upper surface of the glass and the movable seat 24 moves to the bottom end of the fixed seat 23, the cylinder 26 above the movable seat 24 pushes the glass downward. However, since the scribed line is on the upper surface of the glass, the glass cannot be broken smoothly. At this time, there is no need to remove the connector 2. The position of the second clamp body 12 can be adjusted to move the movable seat 24 upward, and the glass can be easily broken by the cylinder 26 below the movable seat 24 and the two cylinders 26 above the fixed seat 23 at the scribed line through the lever principle.
