Description

Technical Field

[0001] This utility model relates to a tool used in daily life, specifically a pruning shears, which has a unique switch safety structure to avoid safety problems caused by accidental triggering. Background Technology

[0002] Pruning shears are a type of pruning tool, currently powered by lithium batteries. As they are shears, they carry certain risks. To prevent accidental contact and personal safety issues, pruning shears are generally designed with a safety mechanism, which is currently quite complex. Utility Model Content

[0003] The purpose of this invention is to provide a pruning shear with a switch safety mechanism. The technical problem to be solved is to provide a pruning shear with a novel switch safety mechanism.

[0004] A pruning shears with a switch safety includes a housing, a trigger, a safety button, and a torsion spring. The trigger is hinged to the housing, and the safety button is hinged to the trigger. The safety button is equipped with a torsion spring so that the initial use directions of the trigger and the safety button are at an angle and not in the same direction. In the initial position, the safety button forms an abutment limit engagement with the housing or a component inside the housing, preventing the trigger from being pressed in the initial position of the safety button.

[0005] The trigger has an open groove at the position where it engages with the safety button. The opening faces inward toward the housing. The two side walls of the opening have round holes with fixing pins inside. The fixing pins pass through the torsion spring and the safety button and are fixed to the trigger. The groove accommodates a portion of the safety button. The position where the trigger engages with the safety button also has a through groove, which forms the rotation space for the safety button and accommodates other parts of the safety button.

[0006] One end of the torsion spring abuts against the housing or a component inside the housing, and the other end abuts against the safety button.

[0007] The safety button has a button body and a protrusion. The button body has a groove at one end to facilitate the placement of a torsion spring. The protrusion protrudes outward from the button body and has a hole to facilitate engagement with a fixing pin. This hole is aligned with the hole of the torsion spring.

[0008] One end of the trigger is formed into a hook-shaped structure, and the other end has a rotating column and a rotating wall. The rotating column is hollow inside and fits on the cylinder of the housing. The rotating wall is fixed on the rotating column and is hinged to a pry plate inside the housing. A spring is arranged between the pry plate and the housing, and the spring restores the trigger to its initial position through the pry plate.

[0009] The beneficial effects of this utility model are: the initial position of the safety button intersects with the trigger in an X shape. Since the inside of the safety button is pressed against the housing or a component inside the housing, the trigger cannot be pressed, thus forming a safety safety structure; when the scissors need to be used, the safety button is rotated so that the safety button changes from its original inclined longitudinal state to an aligned state with the trigger and is housed inside the trigger, so that normal operation can be performed after pressing the trigger.

[0023] Please refer to Figures 1 to 5The pruning shears in the diagram mainly consist of a housing 1, a trigger 2, a safety button 3, a torsion spring 4, and a rocker arm 7. The housing 1 serves as the outer shell of the shears, supporting and fixing other components or limiting the initial position of the safety button 3. The trigger 2 acts as a button, activating the shears when pressed. The safety button 3 acts as a safety mechanism, requiring a change in its initial state to drive the trigger 2 and activate it. The torsion spring 4 acts as an elastic component, maintaining the safety button 3 in its initial position when not rotated. The rocker arm 7 acts as a reset mechanism for the trigger 2. In practical applications, these components can be further optimized, existing components can be replaced, or additional components can be added. The innovation of this design is the addition of a safety button 3 to the original trigger 2. The initial operating directions of the trigger 2 and the safety button 3 are not the same. Without rotating the safety button 3, the trigger 2 cannot be activated due to the limiting component at the rear of the safety button 3, thus improving safety and preventing accidental activation when not in use.

[0024] The shell 1 in the figure adopts the existing shell 1 structure that comes with pruning shears, or can be modified without creative optimization to adapt to other optimized components.

[0025] The trigger 2 in the figure is generally a component with a rotating column 21 and rotating wall 22 at the head, a straight rod in the middle, and a hook-shaped structure at the tail. The rotating column 21 is hollow inside to facilitate a hinged engagement with the cylinder 11 of the housing 1. The rotating wall 22 is mounted on the rotating column 21 and has a plate-like structure to facilitate a hinged engagement with the end of the rocker arm 7 on the housing 1. The end of the rocker arm 7 can also be designed as a plate. As shown in the figure, a spring 5 is installed on the rocker arm 7 at its lower right side. This spring 5 pushes the rocker arm 7 upward, thereby returning the trigger 2 to its initial position. The straight rod structure is designed with two structures: an open groove 23 and a through groove 24. The groove 23 and the through groove 24 together accommodate and enclose the safety button 3. The groove 23 is used to place the safety button 3 after rotation, and the through groove 24 is used for the safety button 3 to pass through in its initial position. The opening of the groove 23 faces inward towards the housing 1. Circular holes 25 are designed on both sides of the opening, allowing a fixing pin 6 to be inserted into these holes 25 for securing the safety button 3. During securing, the fixing pin 6 passes through the torsion spring 4 and the safety button 3, and is fixed to the trigger 2. The through groove 24 has a square structure, forming the rotation space for the safety button 3.

[0026] The torsion spring 4 in the figure is a conventional component. One end of it abuts against the housing 1 or a component inside the housing 1, and the other end abuts against the safety button 3. When the pruning shears are not in use, the spring force keeps the safety button 3 in its initial position, that is, in a tilted longitudinal state, while maintaining an X-shape with the trigger 2, so that the initial use direction of the trigger 2 and the safety button 3 have an angle and are not in the same direction.

[0027] The safety button 3 in the figure is designed with a button body 31 and a protrusion 32. The button body 31 is the main structure of the safety button 3, and it has an open groove 311 to facilitate the placement of one end of the torsion spring 4. The protrusion 32 protrudes outward from the button body 31, and a hole is designed at the protrusion position to facilitate the assembly with the fixing pin 6 to complete the hinge connection between the safety button 3 and the trigger 2. At the same time, the direction of the hole is aligned with the direction of the hole in the torsion spring 4, which facilitates the fixing of the torsion spring 4. As shown in the figure, when the safety button 3 is in the initial position, the inner end of the safety button 3 forms an abutment limit assembly with the housing 1 or the components inside the housing 1. That is, the housing 1 or the components inside the housing 1 always block the movement of the safety button 3, thereby preventing the trigger 2 from being pressed in the initial position of the safety button 3. When the safety button 3 is rotated, it is kept horizontally aligned with the trigger 2, that is, it is accommodated in the trigger 2. The trigger 2 is no longer blocked, so when the trigger 2 is pressed, it can operate normally.
