Description

Technical Field

[0001] This utility model belongs to the field of cutting tools, and relates to reciprocating saws, and in particular to a reciprocating saw with a locking structure. Background Technology

[0002] The reciprocating saw includes a housing, a reciprocating rod, a transmission gear, a connecting rod, a shift fork, and a lifting plate. The front end of the connecting rod is rotatably connected to the rear end of the reciprocating rod. The lifting plate is pivotally connected to the housing and contacts the front end of the shift fork. The lifting plate also contacts a sliding bearing located at the rear end of the reciprocating rod. The angle α formed by the lines connecting the axes of the first eccentric shaft, the transmission gear, and the second eccentric shaft is an obtuse angle. When the connecting rod moves forward, the shift fork moves backward; this opposite movement partially counteracts the vibration caused by the reciprocating motion of the reciprocating rod.

[0003] For example, the reciprocating saw disclosed in CN211072040U includes a housing, an electric motor located within the housing, a drive shaft defining a longitudinal axis, and a main shaft generally located within the housing and connected to a oscillating plate. The main shaft includes a through-hole formed by a flow welding process, wherein the through-hole extends through the main shaft to receive the oscillating plate.

[0004] Because the switch and handle of the aforementioned reciprocating saw are located in the same chamber, there is a possibility of accidentally activating the switch while holding the reciprocating saw for cutting operations, causing the reciprocating saw to shut down and affecting its use.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0028] Figure 1 and Figure 2 As shown, a reciprocating saw with a locking structure includes a body 1, a handle 2 fixedly connected to the body 1, a switch 3 provided inside the handle 2, and a protective cover 5 for blocking the switch 3 slidably connected inside the handle 2. The protective cover 5 slides along the length of the handle 2, and a protrusion 4 is fixedly connected to the inner wall of the protective cover 5. When the protective cover 5 slides towards the side closer to the switch 3, the protrusion 4 contacts the switch 3.

[0029] Figure 1 and Figure 2As shown, when it is necessary to open the reciprocating saw, slide the protective cover 5 towards the side closer to the switch 3. Since the protective cover 5 is arc-shaped, it is easy for the hand to push the protective cover 5 to slide. At this time, the distance between the protective cover 5 and the switch 3 gradually decreases until the protrusion 4 contacts the switch 3, thereby opening the reciprocating saw. Since the protrusion 4 is elastic, it can deform when it contacts the switch 3, thereby reducing the force exerted by the protrusion 4 on the switch 3, thus protecting the switch 3. After opening the switch 3, the protective cover 5 is reset, thereby blocking the switch 3 and preventing the hand from being unable to grip the handle 2.

[0030] Figures 1-4 As shown, a groove 14 is provided on the handle 2, one end of the protective cover 5 extends into the groove 14, and a slot 6 is provided on the handle 2 to facilitate the insertion of the other end of the protective cover 5. A spring 7 is fixedly connected between the slot 6 and the other end of the handle 2. When the other end of the protective cover 5 is inserted into the slot 6, the spring 7 deforms.

[0031] Figures 1-4 As shown, when the protective cover 5 slides closer to the switch 3, one end of the protective cover 5 slides in the groove 14, while the other end gradually penetrates into the slot 6. At this time, the spring 7 deforms due to compression until the switch 3 is opened. After that, the force pushing the protective cover 5 to slide is removed. Since the force is removed, the deformed spring 7 can push the protective cover 5 to reset, thereby separating the protrusion from the switch 3. In this design, the spring 7 plays the role of pushing the protective cover 5 to reset, while the groove 14 plays the role of limiting the sliding range of the protective cover 5.

[0032] Figures 1-4 As shown, the other end of the protective cover 5 is fixedly connected to a limiting block 13 that can abut against the inner wall of the slot 6. When the deformed spring 7 pushes the protective cover 5 to reset, the limiting block 13 abuts against the inner wall of the slot 6, thereby preventing the other end of the protective cover 5 from separating from the slot 6 and ensuring the normal use of the protective cover 5.

[0033] Figures 1-4 As shown, a locking block 11 for fixing the protective cover 5 is slidably connected in the slide groove 14. The locking block 11 slides along the depth direction of the slide groove 14. An L-shaped block 8 is fixedly connected to one end of the protective cover 5 in the slide groove 14. A slot 9 is provided on the locking block 11. The top of the locking block 11 extends to the outside of the handle 2, which can facilitate sliding and pressing the locking block 11. When using a reciprocating saw, the L-shaped block 8 is inserted into the slot 9, and the protective cover 5 is fixed.

[0034] Figures 1-4As shown, after the switch 3 is turned on, the deformed spring 7 pushes the protective cover 5 to slide away from the switch 3. At this time, the protrusion 4 separates from the switch 3 until the limit block 13 and the slot 6 form an abutment. At this time, the L-shaped block 8 is opposite to the slot 9 on the card block 11. The card block 11 is further slid upward so that the L-shaped block 8 is inserted into the slot 9 to fix the protective cover 5, so as to prevent the protective cover 5 from sliding along the slide groove 14 when the reciprocating saw is used.

[0035] Figures 1-7 As shown, a mounting groove 15 is provided on the side wall of the slide 14 near the locking block 11. A slider 12 is fixedly connected to the side wall of the locking block 11 near the mounting groove 15 and slides within the mounting groove 15. When the locking block 11 slides, the slider 12 slides within the mounting groove 15. A spring 10 is fixedly connected between the slider 12 and the inner wall of the mounting groove 15. When the locking block 11 slides downward, the spring 10 deforms.

[0036] Figures 1-7 As shown, when the reciprocating saw needs to be started, the four fingers other than the thumb are held outside the protective cover 5 and pressed against the protective cover 5. The thumb presses down on the end of the locking block 11 that extends to the handle 2. At this time, as the force pushes, the slider 12 on the locking block 11 gradually slides down along the mounting groove 15. At the same time, due to the compression of the slider 12, the spring 10 deforms and the L-shaped block 8 gradually separates from the groove 9. At this time, the locking block 11 releases the fixation of the protective cover 5 and the switch 3 can be opened by pushing the protective cover 5 closer to the switch 3 with the remaining four fingers. At this time, the spring 7 deforms due to the compression of the protective cover 5. In this design, the slider 12 and the mounting groove 15 limit the sliding range of the locking block 11.

[0037] Figures 1-7 As shown, after the switch 3 is turned on, the four fingers are released. At this time, the deformed spring 2 7 can push the protective cover 5 to slide away from the switch 3. During the sliding process, the protrusion separates from the switch 3 until the limit block 13 abuts against the inner wall of the slot 6. At this time, the slot 9 on the locking block 11 is opposite to the L-shaped block 8 on the protective cover 5. After that, the thumb that pressed the locking block 11 is released, and the deformed spring 10 can push the slider 12 and the locking block 11 to reset. During the reset process, the L-shaped block 8 is locked into the slot 9, thereby fixing the protective cover 5 and preventing accidental contact that would cause it to slide. In this design, the spring 10 plays the role of pushing the locking block 11 to reset, and the locking block 11 can fix the protective cover 5, further improving the anti-accidental contact effect of the protective cover 5.
