[0002] Both invisible hinges and hinges are important hardware components for connecting window frames and window sashes to achieve the opening and closing of window sashes. In the early stage, due to reasons such as high price and insufficient technical maturity of hinges, many families mostly chose hinges as the articulated components to connect window sashes. However, as the hinge technology became more mature and stable in the later stage, people were willing to replace the originally installed hinges on windows with hinges because of the functionality of the hinges. However, when installing hinges, it is necessary to punch holes in the profiles in advance. The originally installed windows with hinges do not have reserved holes for the hinges to pass through. Therefore, when replacing hinges with hinges, it is necessary to punch holes in the window sashes that have been assembled into finished products. At present, the existing punching method is to open the profile through a saw blade or a flat chisel. This method is complex in operation and low in accuracy, and may damage the profile, causing the profile to crack and resulting in water leakage problems. Content of the Utility Model

[0028] Embodiment 1

[0029] As Figures 1 to 6As shown in the figure, the present utility model provides a hole - punching tool for installing a hinge, which includes a holding handle 1 and a pressing handle 2. The holding handle 1 is mainly used for the user to stably hold the tool and provide a hand - held support point during operation. The pressing handle 2 is directly related to the action control part of the hole - punching process.

[0030] A resilient device is arranged between the holding handle 1 and the pressing handle 2 to maintain the stability of the operation and improve the accuracy of hole - punching. The holding handle 1 and the pressing handle 2 are movably connected through a first connecting mechanism. One side of the holding handle 1 is fixedly connected to a base 7 through a third connecting mechanism. A stamping part 8 is arranged inside the base 7, and the stamping part 8, the holding handle 1 and the pressing handle 2 are movably connected through a second connecting mechanism.

[0031] The first connecting mechanism includes a lower connecting hole 203, a shaft hole 102 and a pivot 6. The lower connecting hole 203 is arranged at the top of the pressing handle 2, the shaft hole 102 is arranged at the top of the holding handle 1, and the shaft hole 102 and the lower connecting hole 203 are movably connected through the pivot 6. When the staff applies force downward through the pressing handle 2, the holding handle 1 remains relatively stable, and the pivot 6 ensures the smooth transfer of force from the pressing handle 2 to the stamping part 8, so as to effectively perform the hole - punching operation.

[0032] The second connecting mechanism includes an upper connecting hole 202, a first limiting hole 101, a first connecting hole 801, a connecting piece 11, a connecting bolt 10 and a pin shaft 5. The upper connecting hole 202 is arranged above the lower connecting hole 203, the first limiting hole 101 is arranged above the shaft hole 102, the first connecting hole 801 is arranged at one end of the stamping part 8 away from the base 7, and the connecting piece 11 includes a third limiting hole 111 and a second connecting hole 112. The connecting piece plays a role in limiting and guiding.

[0033] The upper connecting hole 202, the first limiting hole 101 and the third limiting hole 111 are movably connected through the pin shaft 5, allowing the stamping part 8 to move freely within a certain range while setting limits to prevent excessive movement and ensuring the accuracy of the hole - punching action. The first connecting hole 801 and the second connecting hole 112 are fixedly connected through the connecting bolt 10, ensuring an indirect but reliable mechanical transmission path between the stamping part 8, the holding handle 1 and the pressing handle 2. During work, under the action of the first limiting hole 101 and the connecting piece 11, the connecting bolt 10 slides in the first limiting hole 101, the connecting bolt 10 drives the connecting piece 11 to move, and then drives the impact head 802 to move to realize hole - punching. And the mechanical transmission through the connecting piece 11 can be more labor - saving.

[0034] A slot hole 104 is provided at the upper end of the holding handle 1. A through cavity 702 communicating with the slot hole 104 is provided on the base 7. A punch head 802 matching the through cavity 702 is provided on the stamping part 8. The stamping part 8 can be inserted into the base 7 and the holding handle 1 from the slot hole 104 and the through cavity 702 and move along the through cavity 702. Notch openings 803 are provided on the side walls of one end of the stamping part 8 close to the punch head 802, enabling the punch head 802 to punch the profile. When performing the punching operation, the profile is placed at the notch opening 803, and punching is achieved by pressing the pressing handle 2. The punch head 802 is a replaceable punch head. The punch head 802 is connected to the stamping part 8 through a dovetail groove, enabling the punch head 802 to be easily replaced when damaged. Notches 701 are provided on both sides of the base 7, and a slot hole matching the punch head 802 is provided inside the base 7, facilitating the limitation of the advancing direction of the punch head 802 to prevent deviation.

[0035] The third connecting mechanism includes a first screw hole 103. The first screw hole 103 is provided on the upper and lower sides of the slot hole 104. A second screw hole 703 matching the first screw hole 103 is provided on the base 7. The first screw hole 103 and the second screw hole 703 are fixedly connected by a screw 9, thereby tightly and firmly connecting one end of the base 7 and the holding handle 1 away from the pressing handle 2, ensuring that the overall structure of the punching tool remains stable even when a large punching force is applied, avoiding loosening or slipping, and improving the safety and accuracy of punching.

[0036] The spring-back device includes a second limit bolt 4. A torsion spring 3 is sleeved on the second limit bolt 4. A second limit hole 201 is provided on the pressing handle 2. The torsion spring 3 is fixedly connected to the pressing handle 2 through the second limit bolt 4 and the second limit hole 201. One end of the torsion spring 3 abuts against the groove inside the inner wall of the holding handle 1, and the other end abuts against the groove inside the inner wall of the pressing handle 2. When the pressing handle 2 is pressed down, the torsion spring 3 transmits the force to the holding handle 1, and the torsion spring enables the pressing handle to spring back to the reset position after the punching work is completed.

[0037] A first outer shell 12 is sleeved on the lower part of the holding handle 1, and a second outer shell 13 is sleeved on the lower part of the pressing handle 2. Both the first outer shell 12 and the second outer shell 13 play the role of protecting and beautifying the handle. The outer side of the first outer shell 12 is arc-shaped, conforming to the human hand holding angle and increasing the comfort of the hand feeling. A first protrusion 122 is provided on the outer side of the first outer shell 12, and a second protrusion 132 is provided on the outer side of the second outer shell 13, which can enhance the anti-slip property during operation. A handle pull ring 121 is provided at the bottom of the first outer shell 12, and a limit block 131 is provided at the bottom of the second outer shell 13. In the non-use state, the holding handle 1 and the pressing handle 2 can be connected together through the handle pull ring 121 and the limit block 131, facilitating the reduction of the volume for storage.

[0038] Working principle: When performing the punching operation, place the stamping part 8 of the punching tool in the groove at the corner of the profile, then move the impact head 802 of the stamping part 8 to the inner wall of the groove and fit it with the inner wall of the groove. At this time, the base 7 abuts against the outer side of the profile, and the impact head 802 abuts against the inner side of the profile (as Figure 3 shown). Press the pressing handle 2 to drive the stamping part 8 to move in the direction of the pressing handle 2, so that the impact head 802 completes the punching (as Figure 4 shown). After the punching is completed, release the pressing handle 2, and the stamping part 8 will automatically return to its original position under the action of the torsion spring 3, completing the entire punching operation (as Figure 5 shown), and the waste material generated after punching will fall from the impact head 802. Finally, buckle the handle pull ring 121 on the limit block 131 to complete the storage of the punching tool (as Figure 6 shown).

[0039] Therefore, the punching tool for installing hinges of the present utility model has high precision, is convenient to operate and is easy to carry.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
