[0022] The specific embodiments described herein are intended to be illustrative only and are not intended to limit the present application. It will be apparent to those of ordinary skill in the art that other embodiments and / or implementations of the present application can be employed without departing from the true scope and spirit of the present application.

[0023] It should be noted that in the description of the utility model, unless otherwise specified, the orientation or positional relationship indicated by the terms "top", "far", "near" and the like is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. When the absolute position of the described object changes, the relative positional relationship can also change accordingly.

[0024] In addition, the "first", "second" and similar words used in the utility model do not indicate any order, quantity or importance, but are only used to distinguish different parts. "Vertical" is not strictly vertical, but within the allowable error range. "Include" or "contain" and similar words mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0025] It should also be noted that in the description of the utility model, unless otherwise specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; For ordinary skilled persons in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0026] As Figure 1 shown, the utility model provides a kind of laminated glass trimming cutter, including handle 1, tool bit 2 and blade 3. Specifically, the tool bit 2 is arranged at one end of the handle 1, the blade 3 is arranged at the end of the tool bit 2 away from the handle 1, and the top of the tool bit 2 is provided with a guide groove 4 capable of being clamped with the laminated glass.

[0027] By setting the guide groove 4 clamped with the laminated glass on the top of the tool bit 2, it can be ensured that the cutter moves along the predetermined trajectory during trimming, avoiding errors caused by manual operation, and ensuring the flatness and consistency of trimming effect. The guide groove 4 can better fit the edge of the laminated glass during trimming, which can reduce the shaking or deviation of the cutter and enhance the stability of operation. In addition, the setting of the guide groove 4 can also make the trimming process more smooth, reduce the time wasted by frequent adjustment of the position of the cutter, and thus improve the work efficiency.

[0028] As Figure 5As shown in the specific use, the glass is placed on the workbench, one hand holds the glass, and the other hand holds the edge trimming cutter for laminated glass. The operator selects the appropriate guide groove 4 according to the edge shape of the laminated glass, and then tightly fits the guide groove 4 on the edge of the glass. At this time, the blade 3 is opposite the PVB residual material at the middle edge of the two layers of glass. By holding the handle 1 and applying appropriate pressure, the blade 3 is pushed along the edge of the glass from one end to the other end, and the excess PVB material is removed.

[0029] The edge trimming cutter for laminated glass has the advantages of simple structure, convenient operation, high working efficiency and the like, and is suitable for edge trimming processing requirements of various laminated glasses.

[0030] More specifically, as shown in the specific use, the glass is placed on the workbench, one hand holds the glass, and the other hand holds the edge trimming cutter for laminated glass. The operator selects the appropriate guide groove 4 according to the edge shape of the laminated glass, and then tightly fits the guide groove 4 on the edge of the glass. At this time, the blade 3 is opposite the PVB residual material at the middle edge of the two layers of glass. By holding the handle 1 and applying appropriate pressure, the blade 3 is pushed along the edge of the glass from one end to the other end, and the excess PVB material is removed. Figure 2 The guide groove 4 includes a groove bottom 41, a first groove wall 42 and a second groove wall 43. The groove bottom 41 is arranged in parallel with the blade 3. The first groove wall 42 and the second groove wall 43 are arranged on both sides of the length direction of the groove bottom 41, and are connected with the groove bottom 41 perpendicularly. The first groove wall 42 can tightly fit the upper surface of the laminated glass, the second groove wall 43 can tightly fit the lower surface of the laminated glass, and the groove bottom 41 tightly fits the side edge of the laminated glass in the thickness direction.

[0031] Since the side edge of the laminated glass often has a certain curvature, in order to make the guide groove 4 of the edge trimming cutter for laminated glass stably fit the edge of the laminated glass, preferably, the length of the groove bottom 41 is 20mm. This length can ensure sufficient stability of the cutter during edge trimming, and will not cause the fitting degree between the cutter and the glass edge to decrease due to the change of the curvature of the side edge of the laminated glass, especially in the area with large curvature, thereby affecting the edge trimming effect.

[0032] In order to better adapt to the edge trimming of laminated glasses with different thicknesses or different shapes, in some embodiments, the guide groove 4 and the cutter head 2 are detachably connected, and specifically, the guide groove 4 is arranged at the top of the cutter head 2. Since the guide groove 4 is detachable, when the laminated glass to be trimmed is different, the guide groove 4 corresponding to the laminated glass to be trimmed can be easily and quickly replaced without replacing the entire cutter.

[0033] It is understood that the connection method between the guide groove 4 and the cutter head 2 is any suitable connection method known to those skilled in the art. For example, a snap-fit ​​connection, where the guide groove 4 has a snap-fit ​​structure and the cutter head 2 has a corresponding snap-fit ​​groove or protrusion, achieving a stable connection between the guide groove 4 and the cutter head 2 through the interlocking of the snap and the snap-fit ​​groove; or a threaded connection, where the bottom of the guide groove 4 has an external threaded post and the top of the cutter head 2 has a corresponding internal threaded hole, achieving a tight connection by rotating the guide groove 4 to interlock with the threads of the cutter head 2; or a magnetic connection, where magnetic materials are embedded in the guide groove 4 and the cutter head 2 respectively, achieving a connection through magnetic force; or a pin connection, where the guide groove 4 has a insertion hole and the cutter head 2 has a corresponding pin and sealing ring; or an adhesive method, where a layer of uniformly strong adhesive material is provided on the bottom surface of the guide groove 4, etc.

[0034] In some embodiments, the blade 3 is detachably connected to the head 2, specifically, the blade 3 is disposed at the end of the head 2.

[0035] Because the blade 3 is detachable, when it wears or is damaged, the operator can easily remove it and replace it with a new blade 3 without replacing the entire cutter head 2. Furthermore, the detachable design allows the operator to select the appropriate blade 3 according to specific needs and install it onto the cutter head 2. This enhances the practicality and versatility of the laminated glass trimming tool.

[0036] More specifically, a groove 21 is provided at the end of the blade 2 away from the handle 1. The blade 3 is inserted into the groove 21 and forms an interference fit with the groove wall. The shape of the groove 21 matches the blade 3, and the size of the groove 21 is slightly smaller than the size of the blade 3 to ensure the interference fit. At the same time, the groove wall of the groove 21 can be designed as a cone or arc with a certain inclination angle to facilitate the insertion and fixation of the blade 3.

[0037] like Figure 3 As shown, in some embodiments, the handle 1 has a triangular shape, with the two corners of the triangle furthest from the blade 2 rounded. Compared to the traditional frustum-shaped handle, the triangular handle design conforms more naturally to the contours of the hand and distributes hand pressure more evenly when gripping, reducing pressure on the palm and fingers during prolonged use. This effectively reduces hand fatigue and improves operator comfort and work efficiency. Furthermore, the rounded corners furthest from the blade 2 not only avoid the risk of scratches from sharp edges but also make the handle 1 more rounded and safer during use, especially in emergencies, reducing potential injuries from accidental collisions or drops.

[0038] Preferably, the shank of the knife handle 1 is provided with an anti-skid structure. It can be understood that the anti-skid structure can be implemented in various ways on the triangular-shaped shank, for example, fine concave-convex textures such as rhombic, circular or wavy, etc. are processed on the surface of the shank, which increases the friction between the hand and the knife handle 1 to prevent slipping; or a layer of rubber or silicone material anti-skid sleeve is sleeved on the outside of the shank, which has good elasticity and anti-skid performance, and can improve the stability and comfort when holding; or fine anti-skid particles such as plastic particles, ceramic particles or metal particles are embedded on the surface of the shank, which can increase the contact area and friction between the hand and the knife handle 1, thereby preventing slipping.

[0039] In summary, by setting the shank of the knife handle 1 to a triangular shape and adding an anti-skid structure on its surface, the holding stability and safety of the knife handle 1 can be improved, and the comfort and adaptability of use can be improved.

[0040] As shown in Figure 4 In some embodiments, the blade 3 includes a connecting section 31 and a blade edge section 32, the blade edge section 32 is an isosceles triangle, and the hypotenuse of the isosceles triangle is provided with an edge part. The connecting section 31 is used to connect with the end of the knife head 2, and the blade edge section 32 is used to contact and cut into the overflowed PVB material. Since the blade edge section 32 is an isosceles triangle, the edge part on the hypotenuse can maintain a consistent cutting angle during cutting, so that the cut material edge is more flat and smooth.

[0041] The preferred embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited thereto. Within the technical concept of the utility model, the technical scheme of the utility model can be variously simply modified, including various specific technical features being combined in any suitable way, in order to avoid unnecessary repetition, the utility model does not further illustrate various possible combination ways. But these simple modifications and combinations should also be regarded as the disclosed content of the utility model, and all belong to the protection scope of the utility model.
