Description

Technical Field

[0001] The utility model relates to the technical field of garden pruning equipment, in particular to a garden pruning tool which is safe to use. Background Art

[0002] Regular tree pruning is a crucial task in garden maintenance and management. It not only helps beautify the environment and enhance the landscape, but also promotes healthy tree growth and prevents the breeding of pests and diseases. Traditionally, this task has been mainly completed with hand saws, especially when dealing with small to medium-sized branches. Hand saws are widely used due to their high flexibility and relatively low cost.

[0003] However, with the frequent garden pruning operations, the safety hazards of traditional hand saws during use have gradually emerged. Specifically, when using a hand saw, the operator needs to manually hold and push and pull the saw blade to complete the cutting action. During this process, the active area under the saw teeth becomes a high-risk area. Since the saw blade has extremely high sharpness and cutting ability during reciprocating motion, once the operator adjusts the position of the branch with one hand or bends the branch with force, if the operator's attention is slightly distracted or the hand movement is careless, it is very easy to place the fingers or palms on the movement trajectory of the saw teeth, resulting in scratches or even more serious injuries. For the problems in the relevant technology, no effective solution has been proposed so far. Utility Model Content

[0004] In view of the problems in the related art, the utility model provides a garden pruning tool that is safe to use, so as to overcome the above technical problems existing in the existing related art.

[0005] To this end, the specific technical solutions adopted in this utility model are as follows:

[0006] The utility model discloses a garden pruning tool which is safe to use, comprising a metal saw handle, positioning grooves are formed at both ends of the bottom of the metal saw handle, saw teeth are fixedly installed in the positioning grooves, transmission grooves are formed at both ends of the metal saw handle, fixed pulleys are fixedly installed on both sides of the transmission grooves, a winding roller is rotatably mounted on one side of the fixed pulley, a steel wire rope is wound around the surface of the winding roller, both sides of the steel wire rope are slidably mounted on the fixed pulley, a folding telescopic cover is fixedly connected to one side of the surface of the metal saw handle, one end of the folding telescopic cover is fixedly connected to a transmission plate, an adjustment hole is formed on the top of the transmission plate, the steel wire rope is slidably connected to the adjustment hole, and a clamping bolt is threadedly connected above the adjustment hole.

[0007] Furthermore, in order to prevent the transmission plate from swinging when the wire rope slides after being subjected to force, a limit groove is opened on one side of the surface of the serrated plate, and a limit block is fixedly connected to one side of the transmission plate, and the limit block is slidably installed in the limit groove.

[0008] Furthermore, in order to facilitate the disassembly and replacement of the sawtooth piece, a positioning bolt is threadedly connected to one side of the positioning groove, and the sawtooth piece is fixedly installed in the positioning groove by the positioning bolt.

[0009] Furthermore, in order to facilitate hanging the metal saw handle when not in use, a hanging ring is fixedly connected to one side of the surface of the metal saw handle.

[0010] Furthermore, in order to facilitate the tightening of the clamping bolt, a tightening head is fixedly connected to one end of the clamping bolt.

[0011] Furthermore, in order to increase the comfort when using the saw, shock-absorbing pads are fixedly installed on both sides of the surface of the metal saw handle.

[0012] Furthermore, in order to facilitate pushing and adjusting the position of the transmission plate, a pulling ring is fixedly connected to one side of the surface of the transmission plate.

[0013] The beneficial effects of the utility model are as follows: by adjusting the distance between the two transmission plates, when the saw is in use, the two transmission plates are respectively placed on both sides of the branch to be cut, so that the transmission plates drive the folding telescopic cover to protect both sides of the saw blade, and after screwing the clamping bolt, the adjusted transmission plates are fixedly clamped on the wire rope. When the saw blade is performing a cutting task, the two transmission plates are always kept on both sides of the branch to be cut through the transmission of the wire rope, so that when cutting, the saw blade always only exposes a width that is the same as the diameter of the branch to be cut for reciprocating cutting, and the rest of the saw blade is in the folding telescopic cover, which effectively prevents the saw blade from being scratched below the reciprocating cutting path during garden pruning, thereby greatly improving the safety of the hand saw when in use.

[0023] According to an embodiment of the utility model, a garden pruning tool that is safe to use is provided.

[0024] Example 1:

[0025] like Figure 1-Figure 5 As shown, a garden pruning tool that is safe to use according to an embodiment of the present invention includes a bow-shaped metal saw handle 1, a pair of positioning grooves 2 are opened at both ends of the bottom of the metal saw handle 1, and saw teeth 3 are fixedly installed inside the two positioning grooves 2.

Both sides of the steel wire rope 7 are slidably installed on the fixed pulley 5 for realizing the rotation of the steel wire rope 7. Push-pull transmission is performed on the fixed pulleys 5 on both sides of the metal saw handle 1; one side of the surface of both ends of the metal saw handle 1 is fixedly connected to a folding telescopic cover 8 made of plastic material, which is used to protect the surface of the saw tooth blade 3 by telescopic folding; one end of each folding telescopic cover 8 is fixedly connected to a transmission plate 9, and an adjustment hole 10 is opened on the top of the transmission plate 9, and the wire rope 7 is slidably connected to the adjustment hole 10. A clamping bolt 11 is threadedly connected above the adjustment hole 10, and by tightening the clamping bolt 11, the top of the transmission plate 9 is fixedly clamped to the wire rope 7.

[0026] like Figure 1-Figure 5As shown, a limit groove 12 is provided on one side of the surface of the saw tooth piece 3, and a limit block 13 is fixedly connected to one side of the transmission plate 9. The limit block 13 is slidably installed in the limit groove 12 to prevent the transmission plate 9 from swinging when the wire rope 7 slides after being subjected to force; a positioning bolt 14 is threadedly connected to one side of the positioning groove 2, and the saw tooth piece 3 is fixedly installed in the positioning groove 2 through the positioning bolt 14. The saw tooth piece 3 is disassembled and replaced on the metal saw handle 1 by twisting and disassembling the positioning bolt 14; a hanging ring 15 is fixedly connected to one side of the surface of the metal saw handle 1 for facilitating the hanging and placement of the metal saw handle 1 when not in use; a twisting head 16 is fixedly connected to one end of the clamping bolt 11 for facilitating the twisting and adjustment of the clamping bolt 11; shock-absorbing pads 17 are fixedly installed on both sides of the surface of the metal saw handle 1 to improve the comfort of the saw when used; a pulling ring 18 is fixedly connected to one side of the surface of the transmission plate 9, which facilitates the transmission plate 9 to drive the folding telescopic sleeve to push and pull adjustment through the transmission ring.
