[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1-4 As shown, the utility model provides a portable garden pruning saw, comprising a handle 1 and a driving mechanism, a movable block 2 is slidably installed inside the handle 1, a connecting rod 3 is arranged on one side of the movable block 2, an end of the connecting rod 3 away from the movable block 2 passes through one end of the handle 1, and the passing end is connected to a connecting frame 4, a side of the connecting frame 4 away from the connecting rod 3 is provided with a fixing groove 5, a mounting seat 6 is installed on the inner side of the fixing groove 5, a saw blade 7 is arranged on one side of the mounting seat 6, a rotating shaft 8 is arranged at the bottom of the mounting seat 6, and the rotating shaft 8 is rotatably connected to the connecting frame 4, the rotating shaft 8 is specifically a damping rotating shaft, so that the rotation of the mounting seat 6 can maintain a certain damping, a clamping groove 9 is arranged on the top of the mounting seat 6 away from the saw blade 7, and the top of the clamping groove 9 is provided with a A limit block 10 is provided, and a slide groove 11 is provided on the top of both sides of the connecting frame 4. A slider 12 is slidably installed inside the slide groove 11. The slider 12 can move in the up and down direction in the slide groove 11. The top ends of the two sliders 12 pass through the top of the connecting frame 4, and the ends that pass through are commonly connected to a pressing plate 13. A movable groove 14 is provided on both sides of the fixed groove 5. A limit pin 15 is provided between the two sliders 12. The diameter of the limit pin 15 is smaller than the distance between the bottom surface of the limit block 10 and the inner wall of the bottom side of the groove 9, so that the limit pin 15 can cross the limit block 10 and move to the inside of the groove 9. The two ends of the limit pin 15 are respectively fixedly connected to the two sliders 12, and the limit pin 15 passes through the inner sides of the two movable grooves 14 in sequence.

[0023] Among them, the bottom of the slider 12 is provided with a mounting groove, and the inner side of the mounting groove is installed with a spring 16. The bottom end of the spring 16 passes through the bottom of the slider 12, and the two ends of the spring 16 are respectively against the bottom inner wall of the slide groove 11 and the top inner wall of the mounting groove. The elastic force of the spring 16 realizes the rebound reset of the limit pin 15 and the pressing plate 13.

[0024] The position of the limiting pin 15 corresponds to that of the slot 9 , and the limiting pin 15 can enter into the slot 9 during the process of rotating the mounting seat 6 .

[0025] Among them, the limit block 10 is inclinedly arranged on the side away from the saw blade 7. When the inclined surface of the limit block 10 contacts the limit pin 15, the limit pin 15 can be pushed downward so that it can pass over the limit block 10 and enter the inner side of the slot 9, and then rebound under the action of the spring 16 and be locked in the inner side of the slot 9 by the limit block 10.

[0026] Among them, a receiving groove 17 is opened at the bottom of the handle 1, and the receiving groove 17 corresponds to the position of the saw blade 7. The width of the receiving groove 17 is greater than the thickness of the saw blade 7. The receiving groove 17 is used to accommodate the saw blade 7. Under the action of the damping shaft, the saw blade 7 can be kept in the receiving groove 17, thereby preventing the saw blade 7 from injuring people or causing damage to the saw blade 7 due to collision.

[0027] Among them, a driving groove 18 is provided on the surface of the movable block 2, and the driving mechanism includes a turntable 19 rotatably installed inside the handle 1 and a motor 20 fixedly installed inside the handle 1, and the output end of the motor 20 is connected to the turntable 19 through a bevel gear set. A driving rod 21 is also eccentrically arranged on one side of the turntable 19, and the driving rod 21 penetrates into the driving groove 18. The motor 20 drives the turntable 19 to rotate through the bevel gear set. When the turntable 19 rotates, it drives the driving rod 21 to perform circular motion. The driving rod 21 through the circular motion drives the movable block 2 to reciprocate. The reciprocating movable block 2 drives the mounting seat 6 to move back and forth through the connecting rod 3, so that the saw blade 7 performs a sawing action.

[0028] A handle 22 is provided on the top of the handle 1 , and a start button is provided on the inner side of the handle 22 , and the start button is used to start the motor 20 .

[0029] Specific working principle:

[0030] In the utility model, a controller and a battery are also provided inside the handle 1, and the battery, the controller, the start button and the motor 20 are all electrically connected. When the utility model is in use, the saw blade 7 is first rotated until the limit pin 15 enters the slot 9 of the mounting seat 6, and the limit pin 15 is pushed downward under the action of the inclined surface of the limit block 10. After the limit pin 15 passes over the limit block 10, it rebounds and engages with the limit block 10 under the action of the spring 16, thereby fixing the saw blade 7. Then, the start button is pressed to start the motor 20, and the motor 20 drives the saw blade 7 through the bevel gear set. The turntable 19 rotates. When the turntable 19 rotates, it will drive the driving rod 21 to perform circular motion. The driving rod 21 through the circular motion drives the movable block 2 to reciprocate. The reciprocating movable block 2 drives the mounting seat 6 to move back and forth through the connecting rod 3, so that the saw blade 7 performs sawing action. When the sawing is completed, the pressing plate 13 is pressed to make the movable pin avoid the limit block 10, and then the saw blade 7 is rotated into the accommodating groove 17 again. By folding the saw blade 7, the overall size of the utility model can be reduced, and at the same time, the saw blade 7 can be protected to prevent the saw blade 7 from injuring people or being damaged by collision.

[0031] The embodiments of the present utility model are given for purposes of illustration and description. Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
