[0001] The utility model relates to the field of reciprocating saws, in particular to a reciprocating saw with a rotatable handle. Background Art

[0002] A reciprocating saw is a power tool that uses a reciprocating saw blade for sawing. It is a type of electric saw, generally composed of a housing, a motor, a transmission mechanism, a blade lifting mechanism, a saw blade, a switch, etc., and is used for sawing metal plates, pipes, profiles, or cutting bevels on steel pipes.

[0003] For example, the patent application No. 202221232489.1 discloses "a reciprocating saw convenient to use" and specifically discloses: including a housing, a handle is fixedly connected to the bottom of the housing, a sleeve is fixedly connected to one end of the housing, a reciprocating motor is installed on the inner wall of the housing, the output end of the reciprocating motor is in clearance fit with the inner wall of the sleeve, and a saw blade is arranged on the output end of the reciprocating motor. In this reciprocating saw of the utility model, through the front end, rear end and bottom end of one side of the annular track in the handheld mechanism are fixedly connected with clamping groove blocks, the second vertical rod drives the clamping rod to move downward, so that the clamping rod is disengaged from the clamping groove block at the bottom end, and further the movement limitation of the first vertical rod and the second vertical rod is cancelled. The first vertical rod and the second vertical rod drive the slider to slide in the annular track, and the clamping rod can be clamped with the clamping groove block at the front end or the rear end to fix the first vertical rod and the second vertical rod. Thus, it is convenient to hold the handle and the second vertical rod with both hands in sequence according to the left or right handedness of the actual user to drive the reciprocating saw convenient to use. However, in the above technology, the housing and the handle of the reciprocating saw are fixed structures. When the cutting position is too tricky during the cutting process of the reciprocating saw, it is necessary to adjust the holding posture of the handle to achieve the cutting purpose, and the flexibility of use is poor. Therefore, the existing reciprocating saw cannot rotate and adjust the handle during use, and the housing and the handle of the reciprocating saw cannot be installed and disassembled. Therefore, the utility model proposes a reciprocating saw with a rotatable handle to solve the problems existing in the prior art. Summary of the Utility Model

[0004] In view of the above problems, the utility model proposes a reciprocating saw with a rotatable handle. By setting a pull rod, when driving the clamping rod connected to the sliding plate to retract into the fixed cylinder, the spring is compressed at the same time, which is convenient for manually inserting the mounting block connected to the reciprocating saw housing into the mounting sleeve. By setting a spring, the resilience drives the clamping rod connected to the sliding plate to insert into the corresponding clamping groove, so that the mounting block connected to the reciprocating saw housing is fixed in the mounting sleeve, which is convenient for installing and disassembling the reciprocating saw housing and the handle body. By setting a motor body, the output shaft drives the handle body to rotate in the handle housing through a through hole, so that during the rotation of the handle body, the mounting sleeve drives the reciprocating saw housing connected through the mounting block to rotate, realizing the rotation adjustment of the handle of the reciprocating saw.

[0019] In order to deepen the understanding of the utility model, the following will further elaborate on the utility model in combination with embodiments. These embodiments are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.

[0020] According to Figures 1-5 As shown, this embodiment proposes a reciprocating saw with a rotatable handle, including a reciprocating saw housing 1 and a handle shell 5. A saw blade body 2 is arranged on one side of the reciprocating saw housing 1, and a mounting block 3 is installed on the other side of the reciprocating saw housing 1. Card slots 4 are symmetrically opened on the upper and lower sides of the mounting block 3. A through hole 6 is opened at the top of the handle shell 5. A micro - motor body 7 is arranged on the inner bottom wall of the handle shell 5. The output shaft of the micro - motor body 7 is fixedly connected to a rotating shaft 8 through a coupling. The top of the rotating shaft 8 is provided with a handle body 9 and one end penetrates through the through hole 6. A mounting sleeve 10 is arranged on one side of the handle body 9 and sleeved on the outer wall of the mounting block 3. Fixed cylinders 11 are symmetrically installed on the inner bottom of the upper and lower sides of the mounting sleeve 10, and moving holes 12 are opened at the tops of the fixed cylinders 11.

[0021] The inner wall of the fixed cylinder 11 is provided with a sliding groove 13. The inner wall of the sliding groove 13 is provided with a sliding plate 14. A clamping rod 15 is installed at the bottom of the sliding plate 14 and its end penetrates through the clamping groove 4. A pull rod 16 is installed at the top of the sliding plate 14 and its top penetrates through the movable hole 12. A spring 17 is sleeved on the outer wall of the pull rod 16. When the device is in use, the staff manually pulls each pull rod 16 outwards, so that each pull rod 16 drives the sliding plate 14 to slide outwards in the corresponding sliding groove 13 through the movable hole 12. Thus, while the sliding plate 14 drives the clamping rod 15 to retract into the fixed cylinder 11, the spring 17 is compressed. Then, the mounting block 3 connected to the reciprocating saw housing 1 is manually inserted into the mounting sleeve 10. The pulled pull rods 16 are released, so that the resilience of each spring 17 drives the clamping rod 15 connected to the sliding plate 14 to insert into the corresponding clamping groove 4. Thus, the mounting block 3 connected to the reciprocating saw housing 1 is fixed in the mounting sleeve 10, which is convenient for the installation and disassembly of the reciprocating saw housing 1 and the handle body 9. When the handle angle needs to be adjusted, the staff starts the micro motor body 7 through an external control board, so that the output shaft of the micro motor body 7 drives the rotating shaft 8 to rotate. Thus, the rotating shaft 8 drives the handle body 9 to rotate in the handle housing 5 through the through hole 6, so that the handle body 9 drives the reciprocating saw housing 1 connected through the mounting block 3 to rotate during the rotation of the handle body 9, realizing the rotation adjustment of the handle of the reciprocating saw.

[0022] The rotating shaft 8 and the handle body 9 are fixedly connected. The handle body 9 and the through hole 6 and the handle housing 5 are rotatably connected. The output shaft of the micro motor body 7 drives the rotating shaft 8 to rotate. Thus, the rotating shaft 8 drives the handle body 9 to rotate in the handle housing 5 through the through hole 6, so that the handle body 9 rotates.

[0023] The handle body 9 and the mounting sleeve 10 are in close fit. The mounting sleeve 10 and the mounting block 3 are detachably connected. While the sliding plate 14 drives the clamping rod 15 to retract into the fixed cylinder 11, the spring 17 is compressed, which is convenient for manually inserting the mounting block 3 connected to the reciprocating saw housing 1 into the mounting sleeve 10.

[0024] The sliding plate 14 and the sliding groove 13 are slidably connected. The sliding groove 13 and the fixed cylinder 11 are integrally arranged. The staff manually pulls each pull rod 16 outwards, so that each pull rod 16 drives the sliding plate 14 to slide outwards in the corresponding sliding groove 13 through the movable hole 12. Thus, while the sliding plate 14 drives the clamping rod 15 to retract into the fixed cylinder 11, the spring 17 is compressed.

[0025] The sliding plate 14 and the clamping rod 15 are fixedly connected. The clamping rod 15 and the clamping groove 4 are snap-connected. The pulled pull rods 16 are released, so that the resilience of each spring 17 drives the clamping rod 15 connected to the sliding plate 14 to insert into the corresponding clamping groove 4. Thus, the mounting block 3 connected to the reciprocating saw housing 1 is fixed in the mounting sleeve 10.

[0026] The pull rod 16 is movably connected to the movable hole 12, and the movable hole 12 and the fixed cylinder 11 are integrally arranged. By manually pulling each pull rod 16 outwards by the staff, each pull rod 16 drives the slide plate 14 to slide outwards in the corresponding chute 13 through the movable hole 12.

[0027] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] When the rotatable reciprocating saw with a handle is in use, the staff manually pulls each pull rod 16 outwards, so that each pull rod 16 drives the slide plate 14 to slide outwards in the corresponding chute 13 through the movable hole 12. Thus, while the slide plate 14 drives the clamping rod 15 to retract into the fixed cylinder 11, the spring 17 is compressed. Then, the mounting block 3 connected to the reciprocating saw housing 1 is manually inserted into the mounting sleeve 10, and the pulled pull rods 16 are released, so that the resilience of each spring 17 drives the clamping rod 15 connected to the slide plate 14 to insert into the corresponding card slot 4. Thus, the mounting block 3 connected to the reciprocating saw housing 1 is fixed in the mounting sleeve 10, which is convenient for the installation and disassembly of the reciprocating saw housing 1 and the handle body 9. When the handle angle needs to be adjusted, the staff starts the micro motor body 7 through an external control board, so that the output shaft of the micro motor body 7 drives the rotating shaft 8 to rotate. Thus, the rotating shaft 8 drives the handle body 9 to rotate in the handle housing 5 through the through hole 6, and drives the reciprocating saw housing 1 connected to the mounting sleeve 10 to rotate during the rotation of the handle body 9, realizing the rotation adjustment of the handle of the reciprocating saw.
