[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3 The utility model provides a technical solution: a convenient and quick replaceable hand saw, comprising a saw handle body 1, a saw blade 5 is inserted and sleeved on one side of the saw handle body 1, a locking device 8 is threadedly rotatably connected to the upper end of the saw handle body 1, a fixed clamping block 14 is fixedly connected to the inner side of one end of the locking device 8, a clamping groove 9 is fixedly opened on one side of the upper end of the saw handle body 1, the fixed clamping block 14 can be clamped in the inner part of the clamping groove 9, and a limiting block 10 is fixedly connected to the other side of the upper end of the saw handle body 1.
[0018] In this embodiment, by inserting the saw blade 5 into one side of the saw handle body 1, the locking device 8 is rotated by threading so that the fixed block 14 can be clamped in the slot 9. At this time, the locking device 8 can lock and fix the saw blade 5, thereby playing a good fixing effect on the saw blade 5. At the same time, the limit block 10 provided can play a certain limiting role. When the locking device 8 is rotated one hundred and eighty degrees, the locking state can be released, so that the saw blade 5 can be pulled out for replacement. This design method uses a rotational locking method to lock the saw blade 5, so that the saw blade 5 can be well fixed. When replacing, it can be rotated one hundred and eighty degrees to release the locking state and pulled out for replacement. The operation is simple and convenient.
[0019] Specifically, the locking device 8 includes a threaded rod 15, a connecting column 16, a locking half-shaft 17 and an L-shaped rotating block 18. One end of the threaded rod 15 is fixedly connected to the connecting column 16, one end of the connecting column 16 is fixedly connected to the locking half-shaft 17, and one end of the locking half-shaft 17 is fixedly connected to the L-shaped rotating block 18.
[0020] In this embodiment, the L-shaped rotating block 18 is set, and when it rotates, the threaded rod 15 can be threadedly extended and retracted, driving the lower end of the half shaft of the locking half shaft 17 to crimp and lock the single piece. When it rotates one hundred and eighty degrees, the missing half shaft of the locking half shaft 17 can be just stuck at the saw blade 5, so that the saw blade 5 can be released from the locked state. Compared with threaded locking, this type of crimping locking is more convenient to disassemble and install, and is simple to operate.
[0021] Specifically, saw teeth 13 are provided at the lower end of the saw blade 5 , a grip hole 11 is fixedly opened at the center of the saw handle body 1 , and a grip 12 is fixedly connected to one end of the saw handle body 1 .
[0022] In this embodiment, the saw teeth 13 are provided to facilitate cutting, and the gripping hole 11 and the handle 12 are provided to facilitate hand holding for sawing.
[0023] Specifically, the saw handle body 1 includes a lower shell 2 and an upper shell 3 , the upper end cover of the lower shell 2 is connected to the upper shell 3 , one side of the lower shell 2 is fixedly connected to a placement groove 4 , and one side of the surface of the lower shell 2 is fixedly connected to a convex groove 6 .
[0024] In this embodiment, the saw blade 5 is set to be one millimeter, the placement groove 4 is also one millimeter, and the protruding groove 6 is two millimeters. When the saw blade 5 is placed inside the placement groove 4, the saw blade 5 can be crimped and fixed by the protruding protruding groove 6.
[0025] Specifically, a threaded hole 7 is fixedly opened on one side of the lower shell 2 .
[0026] In this embodiment, through the threaded hole 7 , the threaded rod 15 can be threadedly rotated and sleeved inside the threaded hole 7 .
[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
