Technical Field

[0001] The utility model relates to the technical field of garden pruning, in particular to a garden saw for garden pruning. Background Art

[0002] Garden saws are needed in many places during the garden pruning process. As a commonly used tool for garden art pruning, the teeth of the garden saw will produce different degrees of wear after being used for a period of time, and the teeth need to be replaced.

[0003] For example, a garden saw for garden pruning with application number CN201820445197.3 and authorization announcement date 20181225 comprises a saw body and a handle, the rear part of the saw body is fixedly connected to the handle, a T-shaped groove extending to the rear of the saw body is provided on the lower side of the saw body, a stopper is provided at the rear end of the T-shaped groove, a circular upper locking pin hole which is transparent from top to bottom is provided at the front end of the saw body, a saw tooth piece is installed on the lower side of the saw body, a T-shaped protrusion is provided on the upper end of the saw tooth piece, a lower locking pin hole which is not transparent from top to bottom is provided at the front end of the saw tooth piece, and a locking pin is installed on the upper locking pin hole and the lower locking pin hole; the saw tooth piece can be disassembled, assembled and replaced by a special connection structure between the saw body and the saw tooth piece, the saw tooth piece is fixed and locked by the stopper and the locking pin to prevent sliding, and when the saw teeth are severely worn and the saw tooth piece needs to be replaced, only the locking pin needs to be removed and the saw tooth piece needs to be pulled out for replacement without replacing the saw body, thereby greatly reducing the cost of tooth replacement.

[0004] After being used for a period of time, the teeth of a garden saw will be worn to varying degrees, and the teeth need to be replaced. However, replacing the saw blade as a whole is a waste of resources. Therefore, it is urgent to design a garden saw for garden pruning to solve the above problems. Utility Model Content

[0025] Specifically, in this embodiment, it includes a box shell 1, and a sawtooth assembly 3 is arranged inside the box shell 1. The sawtooth assembly 3 includes a mounting shaft 16, and a plurality of clamping blocks 18 are sleeved on the outside of the mounting shaft 16. A sawtooth piece 20 is integrally formed at the bottom end of the clamping block 18. A fixing nut 17 is threadedly connected to one end of the mounting shaft 16. When replacing the sawtooth piece 20, the fixing nut 17 can be unscrewed, and the clamping block 18 with a damaged sawtooth piece 20 can be removed and replaced with a good sawtooth piece 20 to reconstruct a new saw blade structure, thereby reducing waste of resources. The fixing nut 17 is threadedly connected to one end of the mounting shaft 16, and the fixing nut 17 and the clamping block 18 are in contact with each other.

[0026] The utility model provides a garden saw for garden pruning. A sawtooth structure composed of a plurality of clamping blocks 18 and sawtooth pieces 20 is spliced ​​together through a mounting shaft 16. When the saw blade structure of the garden saw is damaged, the fixing nut 17 can be unscrewed, the clamping block 18 with the damaged sawtooth piece 20 can be removed, and a good sawtooth piece 20 can be replaced to reconstruct a new saw blade structure, thereby reducing the waste of resources.

[0027] In one embodiment provided by the present utility model, Figure 1-2 and Figure 4As shown, a handle 4 is installed at one end of the box shell 1 by bolts, and a cover plate 2 is installed at the other end of the box shell 1 by bolts. Three grooves 5 are opened at the bottom of the inner wall of the box shell 1, and the sawtooth pieces 20 are slidably inserted in the grooves 5. Three groups of spring telescopic cylinders 7 are installed at the top of the inner wall of the box shell 1 by bolts, and each group of spring telescopic cylinders 7 has eight spring telescopic cylinders. The output ends of the three groups of spring telescopic cylinders 7 are all installed with connecting pieces 8 by bolts. When the sawtooth assembly 3 is not used, the nut 11 can be rotated again to make the piston 13 fall into the oil The bottom of the box 10 is opened, so that the hydraulic oil 14 no longer pressurizes the piston cylinder 6. At the same time, under the action of the spring telescopic cylinder 7, the connecting piece 8 will rise with the sawtooth assembly 3, so that the sawtooth assembly 3 is retracted into the box shell 1, preventing the sawtooth assembly 3 from stabbing the worker's fingers when the worker carries the garden saw; a card slot 19 is opened on the top of the card block 18, and the connecting piece 8 is slidably inserted in the card slot 19. When the sawtooth assembly 3 needs to be removed, the cover plate 2 can be opened, and then the sawtooth assembly 3 can be pulled to make the card block 18 detach from the connecting piece 8. It is convenient to replace the sawtooth assembly 3, and the connecting piece 8 is slidably connected to the inside of the card slot 19; three groups of piston cylinders 6 are installed on the top of the inner wall of the box shell 1 by bolts, and the piston cylinder 6 is composed of a cylinder barrel and a piston rod, and each group of piston cylinders 6 is nine in number, and a connecting pipe 15 is provided between the nine adjacent piston cylinders 6, and a partition plate 9 is installed on one side of the top of the inner wall of the box shell 1 by bolts, and three oil boxes 10 are installed inside the box shell 1 by bolts, and one end of the three connecting pipes 15 extends to the inside of the three oil boxes 10, and a threaded rod 12 is installed inside the oil box 10 through a bearing, and a nut 11 is welded on the top of the threaded rod 12, and a piston member 13 is threadedly connected to the outside of the threaded rod 12, and hydraulic oil 14 is stored in the oil box 10. Rotate the corresponding nut 11, so that the threaded rod 12 moves with the piston member 13 inside the oil box 10, so that the hydraulic oil 14 inside the oil box 10 flows into the piston cylinder 6, so that the output end of the piston cylinder 6 extends out of the extrusion connecting piece 8, and the sawtooth assembly 3 extends out of the groove 5, so that the garden saw can be used to saw garden plants.

[0028] Working principle: When using the garden saw, the corresponding nut 11 can be turned to make the threaded rod 12 move with the piston 13 inside the oil box 10, so that the hydraulic oil 14 inside the oil box 10 flows into the piston cylinder 6, so that the output end of the piston cylinder 6 extends out of the extrusion connector 8, and the sawtooth assembly 3 extends out of the groove 5, so that the garden saw can be used to saw the garden plants. At the same time, when the sawtooth assembly 3 is found to be worn during sawing, the worker can turn a different nut 11 to extend other sawtooth assemblies 3 inside the box shell 1 to facilitate sawing the garden plants. When the sawtooth assembly 3 is not used later, the nut 11 can be turned again to make the piston 13 fall to the bottom of the oil box 10. The hydraulic oil 14 no longer pressurizes the piston cylinder 6. At the same time, under the action of the spring telescopic cylinder 7, the connecting piece 8 will rise with the sawtooth assembly 3, so that the sawtooth assembly 3 is retracted into the box shell 1, preventing the sawtooth assembly 3 from stabbing the worker's fingers when the worker carries the garden saw; when replacing the saw blade in the sawtooth assembly 3 later, the cover plate 2 can be opened, and then the sawtooth assembly 3 can be pulled to make the clamping block 18 disengage from the connecting piece 8, so as to facilitate the replacement of the sawtooth assembly 3, and when replacing the sawtooth piece 20, the fixing nut 17 can be unscrewed, the clamping block 18 with the damaged sawtooth piece 20 can be removed, and a good sawtooth piece 20 can be replaced to reconstruct a new saw blade structure, thereby reducing the waste of resources.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
