Description

Technical Field

[0001] This utility model relates to the field of wig disinfection technology, and in particular to a lithium-ion universal reciprocating saw with a handle that can assist in lifting. Background Technology

[0002] The development of lithium-ion universal reciprocating saws has evolved from manual to intelligent. Its technology has continuously improved, and its functions have become more complete and diverse. From the simplest manual push-pull operation, it has developed into a modern high-tech product. Based on usage scenarios, it can be divided into household woodworking products, construction worker tools, and garden trimming tools.

[0003] Common lithium-ion universal reciprocating saws only include the function of automatic sawing, but lack the function of assisting in raising the height of the saw blade. This can easily lead to situations where the height of the object being cut exceeds the working range or there are physical obstacles in the working space, causing the saw blade to be unable to fully contact or even completely fail to contact the area to be cut. This limitation in structural design forces users to replace other compatible cutting tools to complete the intended task, affecting the compatibility of reciprocating saws.

[0004] Therefore, to address the problem of the lack of a function to assist in raising the height of the saw blade, which results in the saw blade being unable to fully contact or even make contact with the area to be cut when the height of the object being cut exceeds the working range or when there are physical obstacles in the working space, thus affecting the adaptability of use, a lithium-ion universal reciprocating saw with a handle that can be raised can be designed. Utility Model Content

[0005] To overcome the problem of the lack of a function to assist in raising the height of the saw blade, which causes the saw blade to be unable to fully contact or even make contact with the area to be cut when the height of the object to be cut exceeds the working range or there are physical obstacles in the working space, thus affecting the adaptability of use.

[0006] The technical solution of this utility model is as follows: a lithium-ion universal reciprocating saw with an assisted lifting handle, including an auxiliary grip, a limiting plate, and a lead screw. A main grip is provided above the auxiliary grip, and a drive housing is fixedly connected to the top of the main grip. A saw blade is fixedly connected to the output end of the drive housing. A limiting plate is fixedly connected to the bottom of the main grip. A lead screw is provided inside the auxiliary grip, and the top end of the lead screw passes through the limiting plate and is fixedly connected to a limiting disc. A safety button is fixedly connected to the outside of the drive housing. A power trigger is movably connected to the outside of the main grip. An adjustment mechanism is provided on the auxiliary grip to control the lifting and lowering movement of the saw blade. Guide mechanisms are provided on the main grip and the auxiliary grip to keep the axes of the main grip and the auxiliary grip aligned.

[0007] Preferably, after pressing the lifting button, the signal is transmitted to the GKS18V-200 controller inside the drive housing. After receiving the instruction, the controller starts to operate and sends a start signal to the motor through the control circuit. After the motor starts, it drives the lead screw to rotate. The rotating lead screw and the limit plate form a transmission engagement through a threaded connection, which in turn drives the main handle to move upward in the vertical direction. At this time, the operator's hand is always in the state of holding the auxiliary handle. As the main handle rises, the drive housing is synchronously driven and moved upward. The saw blade installed at the output end of the drive housing is also adjusted in height along with the overall structure, thereby completing the function of adjusting the height of the saw blade.

[0008] Preferably, the adjustment mechanism includes a drive assembly and a control assembly, wherein the drive assembly is used to control the rotational movement of the lead screw, and the control assembly is used to control the start and stop of the motor.

[0009] Preferably, the drive assembly includes a lithium battery box, a mounting frame, and a motor; the bottom of the auxiliary grip is fixedly connected to the lithium battery box, the top of the lithium battery box is fixedly connected to the mounting frame, the inner side of the mounting frame is fixedly connected to the motor, the output end of the motor is fixedly connected to the bottom end of the lead screw, and the motor is used to control the rotational movement of the lead screw.

[0010] Preferably, the control component includes a lifting button; the lifting button is fixedly connected to the top of the lithium battery box and is used to control the start and stop of the motor.

[0011] Preferably, the guiding mechanism includes a limiting component and a threading component. The limiting component is used to keep the axes of the main grip and the auxiliary grip aligned, and the threading component is used for the connecting cable to pass through.

[0012] Preferably, the limiting assembly includes limiting rods and limiting holes; four limiting rods are fixedly connected to the bottom of the main grip, and four limiting holes are opened on the top of the auxiliary grip, with the bottom end of the limiting rod inserted into the limiting hole.

[0013] Preferably, the wiring assembly includes an upper wiring groove and a lower wiring groove; the bottom of the limiting plate has two upper wiring grooves, and the top of the lithium battery box has two lower wiring grooves.

[0014] The beneficial effects of this utility model are:

[0015] This structure uses a controller to drive a motor, which in turn drives a lead screw and a limit plate to form a threaded transmission, achieving synchronous vertical displacement between the main handle and the drive housing. This makes the saw blade height adjustment highly efficient, precise, and stable. At the same time, the auxiliary handle keeps the operating posture constant, effectively reducing the difficulty of operation and improving safety. The overall design combines mechanical transmission and electric control, balancing structural compactness and adjustment sensitivity. The transmission components are tightly fitted, providing high resistance to off-center loads and long-term reliability, making it suitable for continuous operation under complex working conditions.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a lithium-ion universal reciprocating saw with an assisted lifting handle, comprising an auxiliary grip 1, a limiting plate 14, and a lead screw 15. A main grip 11 is positioned above the auxiliary grip 1, and a drive housing 12 is fixedly connected to the top of the main grip 11. A saw blade 13 is fixedly connected to the output end of the drive housing 12. The limiting plate 14 is fixedly connected to the bottom of the main grip 11. The lead screw 15 is located inside the auxiliary grip 1, and its top end passes through the limiting plate 14 and is fixedly connected to a limiting disc 16. A safety button 17 is fixedly connected to the outside of the drive housing 12. A power trigger 18 is movably connected to the outside of the main grip 11. An adjustment mechanism is provided on the auxiliary grip 1 to control the saw blade. The lifting motion is achieved by a guide mechanism on the main handle 11 and the auxiliary handle 1, which keeps the axes of the main handle 11 and the auxiliary handle 1 aligned. By pressing the lifting button 221, a signal is transmitted to the controller (model GKS18V-200) inside the drive housing 12. The controller (model GKS18V-200) then controls the motor 213 to start. The motor 213 drives the lead screw 15 to rotate. The lead screw 15, through a threaded connection with the limit plate 14, drives the main handle 11 to move upward. At this time, the person is holding the auxiliary handle 1. The main handle 11 then drives the saw blade 13 to move upward through the drive housing 12, thereby adjusting the height of the saw blade 13 and realizing the function of assisting in raising the height of the saw blade 13.

[0024] Please see Figures 2-5 In this embodiment, the adjustment mechanism includes a drive assembly and a control assembly. The drive assembly controls the rotation of the lead screw 15, and the control assembly controls the start and stop of the motor. The drive assembly and the control assembly together form a complete adjustment mechanism, which cooperates to control the lifting and lowering movement of the saw blade. The drive assembly includes a lithium battery box 211, a mounting frame 212, and a motor 213. The bottom of the auxiliary grip 1 is fixedly connected to the lithium battery box 211, the top of the lithium battery box 211 is fixedly connected to the mounting frame 212, and the inner side of the mounting frame 212 is fixedly connected to the motor 213. The motor 213 outputs... The output end is fixedly connected to the bottom end of the lead screw 15. The motor 213 is used to control the rotation of the lead screw 15. After receiving the command, the controller starts to operate and sends a start signal to the motor 213 through the control line. After the motor 213 starts, it drives the lead screw 15 to rotate. The control component includes a lifting button 221. The top of the lithium battery box 211 is fixedly connected to the lifting button 221. The lifting button 221 is used to control the start and stop of the motor 213. After pressing the lifting button 221, the signal is transmitted to the controller of model GKS18V-200 inside the drive housing 12.

[0025] Please see Figures 1-5In this embodiment, the guiding mechanism includes a limiting component and a threading component. The limiting component is used to keep the axes of the main grip 11 and the auxiliary grip 1 aligned, and the threading component is used for the connecting wire to pass through. The limiting component and the threading component combine to form a complete guiding mechanism. The two cooperate with each other to keep the axes of the main grip 11 and the auxiliary grip 1 aligned. The limiting component includes limiting rods 311 and limiting holes 312. Four limiting rods 311 are fixedly connected to the bottom of the main grip 11, and four limiting holes 312 are opened on the top of the auxiliary grip 1. The bottom end of the limiting rod 311 is inserted into the limiting hole. Inside the hole 312, when the main handle 11 moves upward in the vertical direction, the limiting rod 311 slides inside the limiting hole 312. The sliding connection between the limiting holes 312 prevents the main handle 11 from shaking due to movement. The wire threading assembly includes an upper wire threading groove 321 and a lower wire threading groove 322. The bottom of the limiting plate 14 has two upper wire threading grooves 321, and the top of the lithium battery box 211 has two lower wire threading grooves 322. The connecting wires in the reciprocating saw all pass through the upper wire threading grooves 321 and the lower wire threading grooves 322 to connect with each component.

[0026] When working, first grip the main handle 11 firmly, then activate the safety button 17, and then pull the power trigger 18. This sends a start signal to the controller (model GKS18V-200) inside the drive housing 12. The controller then activates the brushless motor (model SH-T9119P-H3) inside the drive housing 12, thereby driving the saw blade 13 to perform reciprocating cutting motions. When it is necessary to adjust the height of the saw blade 13, the operator should hold the auxiliary handle 1 and press the lifting button 221. This operation command is transmitted through... The circuit system transmits signals to the controller (model GKS18V-200) inside the drive housing 12. After receiving the signal, the controller sends a start command to the motor 213 through the control line. The motor 213 responds to the command and starts to drive the lead screw 15 to rotate. The rotating lead screw 15 engages with the limit plate 14 through a precision thread, thereby pushing the main handle 11 to move upward along the vertical axis. As the main handle 11 continues to rise, the drive housing 12 moves upward synchronously as a whole, and the saw blade 13 fixed to the output end of the drive housing 12 completes the vertical height adjustment accordingly.

[0027] Through the above steps, after pressing the lifting button 221, the signal is transmitted to the GKS18V-200 controller inside the drive housing 12. After receiving the instruction, the controller starts to operate and sends a start signal to the motor 213 through the control circuit. After the motor 213 starts, it drives the lead screw 15 to rotate. The rotating lead screw 15 and the limit plate 14 are connected by threads to form a transmission engagement, which in turn drives the main handle 11 to move upward in the vertical direction. As the main handle 11 rises, the drive housing 12 is synchronously driven and moved upward. The saw blade 13 installed at the output end of the drive housing 12 also adjusts its height as the overall structure is raised, realizing the function of adjusting the height of the saw blade. This solves the problem that common lithium-ion universal reciprocating saws only have the function of automatic sawing, but lack the function of assisting in raising the height of the saw blade 13. This can easily lead to situations where the height of the object being cut exceeds the working range or there are physical obstacles in the working space, causing the saw blade 13 to be unable to fully contact or even completely fail to contact the area to be cut, resulting in a decrease in the adaptability of the reciprocating saw.
