[0002] The garden saw in the prior art is a manual saw used for sawing tree branches. Among the garden saws, there is a small folding saw, which can fold the blade head into the blade seat of the saw handle.

[0003] The existing Chinese utility model patent CN202122599775.3 discloses a folding saw. The utility model discloses a folding saw, including a handle and a saw blade. A receiving cavity is arranged in the handle. The handle includes a first handle part and a second handle part. One end of the first handle part is rotatably connected to one end of the second handle part so that the first and second handle parts can be rotated to open the receiving cavity or rotated to be close to each other and close the receiving cavity. The saw blade is rotatably connected to the first handle part. The saw blade can be rotated into the receiving cavity or rotated to the outside of the handle. The second handle part is provided with a limiting structure. The saw blade is provided with a first limiting part. When folded, the saw blade is rotated and received in the receiving cavity and the first and second handle parts are rotated to close the receiving cavity. The storage is convenient and the saw blade can be effectively covered to improve safety. When unfolded, the saw blade is rotated outside the handle and the first and second handle parts are rotated to be closed. The limiting structure on the second handle part can cooperate with the first limiting part to limit the rotation of the saw blade, thereby improving the stability of the saw when in use and facilitating the use of the saw. However, the above-mentioned prior art is not perfect in the design of limiting and protecting the cutter head. There are problems such as the limit structure or limit mechanism of the cutter tail, that is, the saw blade tail, is easy to break, the locking teeth are easy to be damaged, and the fixing screws are easy to fall off. Summary of the invention

[0004] The object of the present invention is to provide a button-type angle-adjustable manual garden saw with a foldable saw blade, which has a controllable multi-stage rotation angle adjustment mechanism and a cover clip that protects the blade tail and the saw blade and is laterally fixed by screws. After the angle is adjusted, the entire saw blade can be completely folded and stored in the saw handle, and can also be locked.

[0005] The technical solution adopted by the present invention to solve the problems of the prior art is:

[0006] A button-type angle-adjustable manual garden saw with a foldable saw blade comprises a saw blade and a saw handle, wherein the saw blade is fixedly arranged at the head end of the saw handle, wherein: a rotating disk is arranged at the tail end of the saw blade, the rotating disk is provided with a plurality of position-limiting tongue grooves, and an axial hole is arranged at the center of the rotating disk;

[0007] A saw blade slot is provided at the head end of the saw handle, a hood clip is inserted into the saw blade slot, an outer shaft hole and a key button hole are provided on the hood clip, the tail end of the saw blade is inserted into the hood clip, the shaft screw is inserted into the outer shaft hole and the shaft hole so that the saw blade has a rotating shaft structure, the saw handle is provided with an outer button hole, a key button is inserted into the outer button hole and the key button hole, a key card is provided on the key button, the key button is pressed to move the key card position to switch the opening and closing limit tongue groove to rotate, and always maintain the current angle and position of the hood clip.

[0008] Preferably, the shaft screw is provided with a rotating insert, and the key button is also provided with an insert card. The shaft screw is rotated to switch the rotating insert card to lock in the insert card during the rotation action. The use of this technology can play a role in the horizontal reinforcement of the clasp cover clip, and supplement the gap between the clasp cover clip and the saw blade slot of the saw handle. It can also switch the rotating insert card to lock in the rotating insert action to realize whether the key button can be pressed, so as to prevent the saw blade from being misplaced when the key button is pressed accidentally when sawing branches, or the key button is pressed accidentally and the locking fails in the folded state, thereby adding a safety measure.

[0009] Preferably, the cover clip is made of metal, including a front piece and a rear piece, which are integrally bent into a U shape, and a saw blade is inserted between the front piece and the rear piece. The use of this technology can strengthen the saw blade slot structure set at the head end of the saw handle as a whole, increase the saw blade tail end structure and fill the overall structural weakening caused by the need to cut the hollow limit tongue groove of the rotating disk structure.

[0010] Preferably, a tail plug is provided at the tail end of the bell cover clip, a plug slot is provided in the saw blade slot, and the tail plug is inserted into the plug slot for fixing. With this technology, the bell cover clip can be very firmly positioned after being inserted into the saw blade slot, increasing the bearing capacity of the saw blade when it is pressed down.

[0011] Preferably, the key button includes a button head, a key column, and a spring. The button head is arranged at the head end of the key column, and the spring is arranged at the tail end. The key column is square, and the outer button hole and the key button hole are both square. After the key column of this structure is inserted into the outer button hole and the key button hole, both the force of the saw blade itself when sawing and the stress of the clasp clip transmitted to the saw handle to cause the clasp clip to shift will be locked, and the above two will not be allowed to rotate or move, thereby increasing the overall firmness.

[0012] Preferably, a convex stopper is provided in the key card, which further provides the key card with the ability to accurately position the limit tongue, that is, when rotating, the key card can first be stuck on the outer surface of the rotating disk, and then continue to rotate, and the convex stopper automatically snaps into the limit tongue groove.

[0013] Preferably, the rotating disk is circular, and a plurality of limit tongues are arranged at the positions from 2 o'clock to 19 o'clock, and the limit tongues are hollowed out between the limit tongues to form limit tongue grooves. Such limit tongues can be integrated with the rotating disk, with fast manufacturing speed and high overall strength. The limit tongues can be arranged at the positions from 2 o'clock to 19 o'clock to allow the saw blade to rotate 200 degrees, which is suitable for various required hand-holding angles and sawing angles.

[0014] Preferably, the saw handle is provided with a handle groove, and the saw blade can be completely retracted into the handle groove after the rotation axis is 180° to 90°.

[0015] The beneficial effects of the embodiments of the present application are:

[0016] 1. There are controllable multi-stage rotation angle adjustment mechanisms that cooperate with each other. Specifically, a rotating disk is set at the tail end of the saw blade. The rotating disk is provided with a number of limit tongue grooves as a passive locking structure. A key pressing button is set to move the key card position to switch the opening and closing limit tongue grooves to rotate. This is an active locking mechanism;

[0017] 2. There is a cover clip that protects the blade tail and the saw blade fixing screws and fixes each other horizontally. After the angle is adjusted, the entire saw blade can be completely folded and stored in the saw handle, and can also be locked to ensure that the key button can be pressed. This prevents the saw blade from being dislocated due to accidental pressing of the key button when sawing branches, or the key button from being accidentally pressed and locking ineffective in the folded state, thus adding a safety measure.

[0018] 3. The saw blade can be completely retracted into the handle slot and can be doubly locked in this state to ensure complete safety. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein.

[0029] The portable server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings. Example

[0030] like Figure 1 As shown, the embodiment of the present application provides a button-type angle-adjustable manual garden saw with a folding saw blade, comprising a saw blade 1 for sawing branches and a saw handle 2 for holding the saw blade 1 and holding the hand, and the saw blade 1 is fixedly arranged at the head end of the saw handle 2;

[0031] like Figure 2-3 As shown, a circular rotating disk 3 is arranged at the tail end of the saw blade 1, and a plurality of limiting tongues 24 are arranged at the positions from 2 o'clock to 19 o'clock, and the limiting tongues 24 are hollowed out between the limiting tongues 24 to form limiting tongue grooves 4. Such limiting tongues can be integrated with the rotating disk, with fast manufacturing speed and high overall firmness. The setting at the positions from 2 o'clock to 19 o'clock allows the saw blade to rotate 200 degrees, which is suitable for various required hand-holding angles and sawing angles. The tongue groove 4 is used for limiting, and is a hole structure in the hole tooth limiting structure.

[0032] A shaft hole 5 is also provided at the center of the rotating disk 3 for passing the shaft screw 10 described below;

[0033] like Figure 3 , 4As shown, a saw blade slot 6 is provided at the head end of the saw handle 2, and a cover clip 7 is inserted into the saw blade slot 6. The cover clip 7 is made of metal and includes a front piece 16 and a rear piece 17. The front piece 16 and the rear piece 17 are integrally bent into a U shape, and the saw blade 1 is inserted between the two. The use of this technology can strengthen the saw blade slot structure provided at the head end of the saw handle 2 as a whole, increase the saw blade tail end structure, and fill the overall structural weakening caused by the need to cut a hollow limit tongue groove for the rotating disk structure.

[0034] like Figure 4 As shown, the clasp clip 7 is provided with an outer shaft hole 8 and a key button hole 9, a part of the tail end of the saw blade 1 includes a rotating disk 3 inserted into the clasp clip 7, and the shaft screw 10 is inserted into the outer shaft hole 8 and the shaft hole 5 so that the saw blade 1 has a rotating shaft structure, the saw handle 2 is provided with an outer button hole 11, and the outer button hole 11 and the key button hole 9 are inserted to set a key button 12, and the key button 12 is provided with a key card 13. Pressing the key button 12 moves the position of the key card 13 to switch the opening and closing limit tongue groove 4 to rotate, and always maintain the current angle and position of the clasp clip 7.

[0035] The specific usage is: Figure 1 As shown in FIG. 1 , it is a picture of the present invention in use. In this state, the user holds the saw handle 2 normally and moves it back and forth to perform sawing. During this use process, the force is mainly fed back to the saw body from bottom to top, and to the saw tail from front to back. In the traditional structure, if the saw blade is a rotating shaft structure, the saw tail will eventually break due to excessive force or long-term use. Figure 1 As shown, in order to adapt to the adjustment of the saw blade to cut the hollow rotating disk 3 structure at different angles, a plurality of tongue grooves 4 are provided. When the scheduling adjustment is performed, Figure 6 As shown, the key button 12 is pressed down, and the key button 12 moves upward, and the convex stopper 23 is displaced upward from the tongue groove 4. The entire rotating disk 3 is no longer locked and can be rotated. Now the key button 12 is directly loosened, because the spring reset ability at the upper end of the key button 12 pushes the key button 12 downward, and a convex stopper 23 is arranged in the key card 13. It further provides the key card with the ability to accurately position the limit tongue, that is, when rotating, the key card can be first stuck on the outer surface of the rotating disk, and then continue to rotate, and the convex stopper automatically snaps into the limit tongue groove. The convex stopper 23 fits the outer wall of the limit tongue 24. When the saw blade 1 rotates to the next required tongue groove 4, the convex stopper 23 will automatically snap into the tongue groove 4 at the first time to achieve the function of locking the saw blade angle;

[0036] To overcome the defects of the saw blade cutting the hollow rotating disk 3 at different angles, and the defects of the saw tail breaking due to excessive force or long-term use, the present structure adopts 1. The tail end of the bell cover clip 7 is provided with a tail plug 18, and a plug slot 19 is provided in the saw blade slot 6, and the tail plug 18 is inserted into the plug slot 19 for fixing. After the bell cover clip is inserted into the saw blade slot, the position can be very tight, which increases the bearing capacity of the saw blade when it is pressed down.

[0037] like Figure 3 , 4 As shown, the shaft screw 10 is provided with a rotating insert 14, and the key button 12 is also provided with an insert card 15. The rotating shaft screw 10 is rotated to switch the rotating insert 14 to be locked in the insert card 15. The present technology can play a role in reinforcing the action of the clasp clip laterally, and supplement the gap between the clasp clip and the saw blade slot of the saw handle 2. The key button can be switched to be locked in the insert card 15 to realize whether the key button can be pressed, so as to prevent the saw blade from being misplaced due to the key button being pressed accidentally when sawing branches, or the key button being pressed accidentally and locked in the folded state, thereby adding a safety measure.

[0038] 3. If Figure 2 As shown, the key button 12 includes a button head 20, a key column 21, and a spring 22. The button head 20 is arranged at the head end of the key column 21, and the spring 22 is arranged at the tail end. The key column 21 is square, and the outer button hole 11 and the key button hole 9 are both square. After the key column of this structure is inserted into the outer button hole 11 and the key button hole 9, both the force of the saw blade itself when sawing and the stress of the clasp clip that is secondary transmitted to the saw handle 2 to cause the clasp clip to shift will be locked, and the above two will not be allowed to rotate or move, thereby increasing the overall firmness.

[0039] The saw handle 2 is provided with a handle groove 25. The saw blade can be completely received in the handle groove after the rotation axis is 180° to 90°. Figure 7 shown.

[0040] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
