Gardening shear labor-saving guiding mechanism

This creation is about a gardening shear, especially a gardening shear-saving guiding mechanism that improves stability, smoothness and durability.

According to the gardening shears, a gardening shear is a widely used gardening tool. The general gardening shears are provided with an elastic member between the two grips. When the user wants to perform the shearing work, the elastic force of the elastic member must be directly overcome. The two grips are relatively close to each other to complete the cutting action, and the operation is laborious and easily causes the user's hand fatigue or sports injury, so that the labor-saving gardening shears are created.

As shown in the first and second figures, it is a conventional labor-saving gardening shear, comprising: a first handle 10, a second handle 20, a blade 30, an elastic member 40 and a pulley 50. The first handle 10 is provided with an anvil 101 and a through hole 102. The second handle 20 is pivotally connected to the first handle 10. The inner side is provided with a receiving slot 201. The blade 30 is worn. The slot 102 of the first handle 10 is pivotally connected. One end is provided with a blade 301 corresponding to the anvil 101 of the first handle 10, and the other end is provided with a diagonal sliding section 302. The elastic member 40 is assembled on the same. Between the blade 30 and the first handle 10, the blade 30 is elastically stretched relative to the first handle 10. The pulley 50 is pivotally disposed in the receiving slot 201 inside the second handle 20 by a shaft 501. The sleeve is freely rotatable, and has a flat tread 502 on its circumference for the sliding portion 302 of the blade 30 to abut against.

However, the conventional labor-saving gardening shears can use the wheel surface 502 of the pulley 50 for the sliding section 302 of the blade blade 30 to abut against the sliding blade 302, and generate thrust on the blade blade 30, and the elastic member 40 is grouped. Provided between the blade 30 and the first handle 10, the compression and recovery stroke is short, so the required elastic member has a relatively small size, and the elastic restoring force is relatively small, thereby achieving a more effortless and labor-saving effect in the shearing operation. . However, the sliding section 302 of the blade 30 only slides against the wheel surface 502 of the auxiliary pulley 50, and there is no guide alignment between the two, so that the blade 30 is easily biased when the force is applied by shearing. Therefore, the shearing is not correct, and the gap between the blade 30 and the slot 102 of the first grip 10 is caused by the yaw, and the wear and the like are shortened, so that the service life of the gardening shear is shortened, so that it is necessary to be improved.

This creator has a practical and labor-saving gardening shear. When cutting, the blade is prone to yaw, which affects the shearing action and shortens the service life of the gardening shear. It is the idea of creation and creation. Try the sample test, and after many corrections and improvements, the final design of the creation.
