[0034] Reference Figure 1 , Figure 2 and Figure 3 A portable saw blade assembly includes a saw blade and a saw blade protective shell 300, the saw blade has a handle 100 for holding and a blade body 200 connected to the handle 100, a saw tooth 210 is arranged on one side of the blade body 200, the saw blade protective shell 300 has a accommodating cavity 301 with a side opening, the accommodating cavity 301 has a first side wall 310 that can fit with the blade body 200 and a second side wall 320 arranged corresponding to the saw tooth 210, the blade body 200 can enter the accommodating cavity 301 from the side opening of the accommodating cavity 301 along a direction perpendicular to the first side wall 310 or along a direction inclined to the first side wall 310, a locking structure is arranged between the handle 100 and the saw blade protective shell 300, when the blade body 200 is placed in the accommodating cavity 301, the locking structure can lock the handle 100 and the saw blade protective shell 300 to prevent the blade body 200 from leaving the accommodating cavity 301.

[0035] It is understandable that if Figure 1 , Figure 2 and Figure 3 As shown, the handle 100 is connected to the upper end of the blade body 200, and a threaded member 110 is provided between the handle 100 and the blade body 200 and connected and fixed by the threaded member 110. The blade body 200 of the saw blade is curved, and a saw tooth 210 is provided on the left side along the width direction, and the other side is a blade back. The second side wall 320 is arranged corresponding to the side of the saw tooth 210 of the blade body 200, and the saw blade guard 300 is provided with a third side wall 330 on the side of the blade back of the blade body 200. The saw blade guard 300 is provided with a accommodating cavity 301 with a front opening, the first side wall 310 is the rear side wall of the accommodating cavity 301, the second side wall 320 is the left side wall of the accommodating cavity 301, and the third side wall 330 is the right side wall of the accommodating cavity 301. The first side wall 310 is connected to the second side wall 320 and the third side wall 330 respectively.

[0036] When the saw blade is not in use, the saw blade can be stored in the saw blade protective shell 300, and the blade body 200 can be installed into the accommodating cavity 301 from the side opening of the accommodating cavity 301 in a direction perpendicular to the first side wall 310, that is, installed into the accommodating cavity 301 in the front-to-back direction. The blade body 200 can be attached to the first side wall 310, and the second side wall 320 and the third side wall 330 are used to protect the saw teeth 210 and the blade back of the blade body 200 respectively, so as to store and protect the blade body 200 and To prevent the saw blade from accidentally injuring someone, the blade handle 100 and the blade shell 300 can be locked by the locking structure to prevent the blade body 200 from leaving the accommodating cavity 301. When using the saw blade, the locking structure on the blade handle 100 and the blade shell 300 can be released first, and the saw blade and the blade shell 300 can be separated, so that the blade body 200 can leave the accommodating cavity 301 from the side opening of the accommodating cavity 301, and the user can hold the blade handle 100 to operate. Through the above structure, the blade body 200 of the saw blade can enter or leave the side opening of the accommodating cavity 301, and the operation of installing and removing the blade is more convenient. When the blade body 200 is placed in the accommodating cavity 301, it can be locked by the locking structure, reducing the possibility of the blade body 200 leaving the blade shell 300, and it is easy to carry.

[0037] In actual application, the saw blade guard 300 may not be provided with the third side wall 330, and the direction in which the blade body 200 enters the accommodating cavity 301 is not limited to only the direction perpendicular to the first side wall 310 (the front-to-back direction shown in the figure), it can also be along the direction inclined to the first side wall 310, such as moving from the right front side into the accommodating cavity 301; the specific structural form of the locking structure can be set according to actual use needs, which will not be described in detail here, and will be explained in detail below.

[0038] In some embodiments, the locking structure includes a knob 400 and a locking hole 101. The locking hole 101 is provided on the handle 100. The knob 400 is rotatably connected to the saw blade guard 300 and is provided with a locking portion 410. The knob 400 can pass through the handle 100 through the locking hole 101 and can rotate relative to the handle 100, so that the locking portion 410 can cooperate with the saw blade guard 300 to clamp the handle 100.

[0039] It is understandable that if Figures 1 to 6 As shown, the locking hole 101 is provided at the lower side of the handle 100 and is through-through from front to back, the saw blade guard 300 is provided with a boss 340, the knob 400 is rotatably connected to the boss 340 and is provided with a locking portion 410, when the blade 200 is placed into the accommodating cavity 301, the knob 400 can pass through the locking hole 101 to penetrate the handle 100, refer to Figure 5 and Figure 6When it is necessary to lock the handle 100 and the blade guard 300, the knob 400 can be rotated to rotate the locking portion 410 to the front side of the handle 100, and the locking portion 410 and the blade guard 300 are used to clamp the handle 100, thereby limiting its movement in the up and down, front and back, and left and right directions, and achieving a locking effect. The structure is simple and the operation is simple and quick.

[0040] Further, refer to Figure 2 , Figure 3 and Figure 4 The cross-sectional shape of the locking hole 101 is non-circular, and the shape of the boss 340 is adapted to the locking hole 101. When the blade 200 is placed in the accommodating cavity 301, the boss 340 is inserted into the locking hole 101, thereby limiting the rotation of the handle 100 relative to the saw blade guard 300. Figure 5 and Figure 6 There are two locking parts 410, and the two locking parts 410 are symmetrical with respect to the rotation axis of the knob 400, so that the handle 100 can be locked at the upper and lower sides of the locking hole 101, achieving a better locking effect.

[0041] In actual application, in addition to the above structure, the locking structure can also be a snap-on structure. For example, a hook is provided on the saw blade guard 300, and a slot is provided on the handle 100. The hook and the slot cooperate to achieve locking between the handle 100 and the saw blade guard 300. The specific setting can be based on actual use needs.

[0042] In some embodiments, a connecting hole 302 is provided on the saw blade guard 300, a first clamping portion 341 is provided inside the connecting hole 302 or at the opening of the connecting hole 302, and the knob 400 has a rotating shaft portion 420, which is rotatably inserted in the connecting hole 302 and is provided with a second clamping portion 421 that is clamped and matched with the first clamping portion 341.

[0043] It is understandable that if Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the inner wall of the connecting hole 302 is provided with a stepped first clamping portion 341, and the rear end of the rotating shaft portion 420 is provided with a second clamping portion 421. When in use, the rotating shaft portion 420 is inserted into the connecting hole 302 and can rotate relative to the connecting hole 302, and the second clamping portion 421 is clamped in the first clamping portion 341 to realize the rotational connection between the knob 400 and the saw blade guard 300.

[0044] Further, refer to Figure 4 , Figure 5 and Figure 6 The shaft portion 420 is provided with an open groove 401 so that the rear end of the rotating portion can shrink and deform, so as to facilitate the shaft portion 420 to be inserted into the connecting hole 302 and enable the second clamping portion 421 to cooperate with the first clamping portion 341.

[0045] In actual application, the first clamping portion 341 may also be disposed at the rear opening of the connecting hole 302 , and the specific structures of the first clamping portion 341 and the second clamping portion 421 may be set accordingly according to actual use requirements.

[0046] In some embodiments, the knob 400 has a first state and a second state and can be rotated and switched between the first state and the second state. When the locking structure locks the handle 100 and the blade guard 300, the knob 400 is in the first state. When the locking structure releases the lock between the handle 100 and the blade guard 300, the knob 400 is in the second state. A positioning structure is provided between the blade guard 300 and the knob 400. When the knob 400 is rotated and switched to the first state and / or the second state, it can be positioned by the positioning structure.

[0047] Understandably, Figure 6 The knob 400 is shown in the first state. At this time, the locking portion 410 rotates to the front side of the handle 100 and cooperates with the saw blade guard 300 to clamp the handle 100. Figure 5 The knob 400 is shown in the second state, at which the locking portion 410 rotates to the position corresponding to the locking hole 101. By providing a positioning structure, when the knob 400 rotates to switch to the first state and / or the second state, it can be positioned by the positioning structure to reduce the possibility of excessive rotation of the knob 400, and at the same time, it is helpful to avoid the knob 400 from loosening and causing locking failure, which is convenient for use.

[0048] Specifically, the positioning structure includes a positioning protrusion 422 and a positioning recess 342. A connecting hole 302 is provided on the saw blade guard 300. The knob 400 has a rotating shaft portion 420. The rotating shaft portion 420 is rotatably inserted into the connecting hole 302. One of the positioning protrusion 422 and the positioning recess 342 is provided on the inner wall of the connecting hole 302, and the other is correspondingly provided on the outer surface of the rotating shaft portion 420. When the knob 400 is rotated to switch to the first state and / or the second state, the positioning protrusion 422 cooperates with the positioning recess 342.

[0049] It is understandable that if Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the positioning recess 342 is provided on the inner wall of the connecting hole 302, and correspondingly, the positioning protrusion 422 is provided on the outer surface of the rotating shaft portion 420. In this embodiment, the positioning protrusion 422 is provided with two and is located at Figure 4On the upper and lower sides of the rotating shaft portion 420 shown, four positioning recesses 342 are provided and are distributed corresponding to the first state and the second state of the knob 400. When the knob 400 is rotated to switch to the first state and the second state, the positioning protrusions 422 can be snapped into the corresponding positioning recesses 342 to realize the rotation positioning of the knob 400, reduce the possibility of excessive rotation and loosening after rotation into place, and facilitate use.

[0050] To achieve a better rotation effect, during the process of the knob 400 rotating and switching between the first state and the second state, a positioning protrusion 422 can be set to abut against the inner wall of the connecting hole 302 to increase the damping feeling of the rotation, thereby increasing the rotation feel feedback of the knob 400 and facilitating use.

[0051] In actual application, a rotation mark can also be set on the handle 100 or the saw blade guard 300 to indicate the direction of the knob 400 and the situation of its rotation into place; the positioning recess 342 can be set to one or more, and the positioning convex portion 422 can also be set to one or more. It can be that one positioning recess 342 is used together with multiple positioning convex portions 422, or multiple positioning recesses 342 are used together with one positioning convex portion 422, or multiple positioning recesses 342 are used together with multiple positioning convex portions 422. 342 may also be arranged on the outer surface of the rotating shaft portion 420, and the positioning protrusion 422 is correspondingly arranged on the inner wall of the connecting hole 302, and its specific arrangement may be changed accordingly according to the actual use needs; in addition to the above structure, the positioning structure may also be positioned by magnetic attraction, such as by setting magnetic attraction portions that can be magnetically attracted to each other at corresponding positions on the outer surface of the rotating shaft portion 420 and the inner wall of the connecting hole 302. When the knob 400 is rotated into place, the magnetic cooperation between the magnetic portions is used to achieve positioning, which may be set accordingly according to the actual use needs.

[0052] In some embodiments, the saw blade guard 300 is provided with a limiting portion 350 on the lower side of the accommodating cavity 301. When the blade body 200 is placed in the accommodating cavity 301, the limiting portion 350 and the first side wall 310 can be respectively located on both sides of the end of the blade body 200 to limit the position of the blade end.

[0053] It is understandable that if Figure 1 , Figure 2 and Figure 7As shown, a bottom shell portion 380 is provided at the lower side of the accommodating cavity 301, and the bottom shell portion 380 is connected to the first side wall 310, the second side wall 320 and the third side wall 330. The limiting portion 350 is provided on the bottom shell portion 380. When the blade 200 is placed in the accommodating cavity 301, the limiting portion 350 and the first side wall 310 are respectively located at the front and rear sides of the lower end of the blade 200 to limit the position of the lower end of the blade 200, thereby better fixing the blade 200 and improving its storage stability. In actual application, the specific structure of the limiting portion 350 can be set accordingly according to actual use needs.

[0054] In some embodiments, a magnetic member 360 is disposed on the first side wall 310 , and when the blade body 200 is placed in the accommodating cavity 301 , the magnetic member 360 can be magnetically coupled with the blade body 200 .

[0055] It is understandable that if Figure 1 , Figure 2 and Figure 3 As shown, a magnetic member 360 is provided on the front side of the first side wall 310. When the blade 200 is about to enter the accommodating cavity 301, the blade 200 can be sucked into the accommodating cavity 301 by the magnetic attraction of the magnetic member 360 on the blade 200. When the blade 200 is placed in the accommodating cavity 301, the magnetic member 360 and the blade 200 are magnetically matched, so that the blade 200 fits the first side wall 310, thereby improving the stability of its storage and facilitating its use. In actual application, the magnetic member 360 can be set accordingly according to actual use needs.

[0056] In some embodiments, a plurality of through holes 303 are provided on the first side wall 310. It is understood that Figure 2 , Figure 3 and Figure 7 As shown, a plurality of through holes 303 are provided on the first side wall 310, and the plurality of through holes 303 are spaced apart in the vertical direction. When the blade 200 is placed in the accommodating cavity 301, the rear side of the blade 200 fits closely with the front side of the first side wall 310 or the gap is small. When the two need to be separated, it is difficult for air to enter between the two, and it is easy to form a negative pressure to hinder the blade 200 from separating from the first side wall 310. By providing the through holes 303, the fitting area between the rear side of the blade 200 and the front side of the first side wall 310 is reduced, and the provision of the through holes 303 can facilitate the entry of air between the two, which is conducive to the blade 200 separating from the first side wall 310. Moreover, by providing the through holes 303, the material of the saw blade guard 300 can also be relatively reduced, reducing the production cost, and its weight can also be relatively reduced, which is convenient for users to carry.

[0057] In practical applications, the shape and number of the through holes 303 can be set according to actual use requirements and are not limited here.

[0058] In some embodiments, the saw blade housing 300 is provided with a clamping portion 370 for clamping. Figure 3 , Figure 5 and Figure 6 As shown, by providing the clamping portion 370, when the user carries the saw blade protective shell 300, the user can clamp it on the waistband of the pants through the clamping portion 370, so that the user can carry the saw blade protective shell 300 for operation and use it conveniently. In actual application, in addition to the structure shown in the figure, the clamping portion 370 can also be a clip, and the specific structure of the clamping portion 370 can be set accordingly according to actual use needs.

[0059] In some embodiments, the handle 100 and / or the blade 200 is provided with a hanging hole 201 for hanging. Figure 1 and Figure 2 As shown, the upper end of the handle 100 and the lower end of the blade 200 are both provided with hanging holes 201. When the saw blade assembly of the utility model is idle, the saw blade assembly can be hung through the hanging holes 201 on the handle 100 and / or the hanging holes 201 on the blade 200 to facilitate the storage and placement of the utility model. In actual application, the hanging holes 201 can also be provided only on the handle 100 or only on the blade 200. The specific shape and distribution position of the hanging holes 201 can be set accordingly according to actual use needs, and are not limited here.

[0060] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
