Description

Technical Field

[0001] The utility model belongs to the technical field of electric tools, and particularly relates to a reciprocating cutting device. Background Art

[0002] A reciprocating cutting device, specifically a jigsaw, is a portable power tool used to cut a variety of materials, including wood, plastic, metal, and some composite materials. It is very flexible in making curved cuts, making it suitable for creating workpieces with complex shapes.

[0003] Conventional jigsaws have a gripping handle with a switch on it. However, some jigsaws do not have a gripping handle in order to allow for easier control during cutting. Users directly hold the casing to operate the saw. The switch on these jigsaws is generally located on the left or right outer wall of the casing, allowing users to start or stop the machine by operating the switch with their thumb or other fingers while holding the casing.

[0004] Since the switch is only provided on one side of the housing, it is generally provided on the left outer wall of the housing, which is convenient for right-handed people to operate with their thumb. However, such a setting is inconvenient for left-handed people, and is also inconvenient for right-handed people who are accustomed to using their index or middle fingers to operate the switch.

[0035] The following are specific embodiments of the present invention, and Figure 1-6 , the technical solution of the utility model is further described, but the utility model is not limited to the following embodiments.

[0036] A reciprocating cutting device includes a shell 100, a driving member 200, a transmission mechanism 300 and a switch assembly, wherein the driving member 200 is arranged in the shell 100, the transmission mechanism 300 is arranged in the shell 100 and connected to the driving member 200, and the switch assembly is arranged on the shell 100 for controlling the start and stop of the driving member 200; wherein the switch assembly includes a first switch assembly 400 and a second switch assembly 500, and the first switch assembly 400 and the second switch assembly 500 are arranged on the outer walls on the left and right sides of the shell 100.

[0037] Preferably, the first switch assembly 400 and the second switch assembly 500 are symmetrically arranged relative to the longitudinal section at the center of the housing 100. It should be noted that in the present embodiment, the reciprocating cutting device is a jigsaw, and in other embodiments, the reciprocating cutting device can also be other electric tools such as a saber saw. The driving member 200 is configured as a driving motor, and the transmission mechanism 300 includes a gear set and a reciprocating rod. The lower end of the reciprocating rod is provided with a saw blade clamping device, and the saw blade is installed in the saw blade clamping device. The gear set converts the rotation of the driving motor into the up and down movement of the reciprocating rod, thereby realizing the up and down cutting of the saw blade. By arranging switch assemblies on the outer side walls on both sides of the housing 100, the user, whether left-handed or right-handed, can conveniently operate the switch to control the start or stop of the reciprocating cutting device by whichever finger he or she is accustomed to using. In this embodiment, the first switch assembly 400 and the second switch assembly 500 are only arranged in different positions, and their internal structures are exactly the same. Therefore, the specific structure of the first switch assembly 400 is introduced below as an example, and the structure of the second switch assembly 500 is not repeated. However, in other embodiments, the structure of the second switch assembly 500 can also be set to be different from that of the first switch assembly 400.

[0038] Specifically, in the reciprocating cutting device of the present invention, the first switch assembly 400 includes a panel 410 and a circuit board 420. A first groove 110 is provided on the outer wall of the housing 100, and the panel 410 is disposed in the first groove 110. A plurality of latches 411 are provided on the side of the panel 410 close to the housing 100. The latches 411 are disposed at the edge of the panel 410. A plurality of slots 111 are provided at corresponding positions of the first groove 110, and the latches 411 and the slots 111 engage with each other in a concave-convex manner. A second groove 120 is provided in the first groove 110, and the circuit board 420 is disposed in the second groove 120. The second groove 120 is provided with a plurality of limit blocks 121 and hooks 122. The limit blocks 121 abut against the side surfaces of the circuit board 420, and the orthographic projections of the hooks 122 on the plane where the circuit board 420 is located partially overlap with the circuit board 420.

[0039] It should be noted that in this embodiment, both the panel 410 and the first groove 110 are configured as elongated strips. A latch 411 is provided at each end of the upper and lower edges of the panel 410, for a total of four latches 411. The first groove 110 is provided with four slots 111 at corresponding positions. The latches 411 engage with the slots 111 to secure the panel 410. Meanwhile, the second groove 120 is provided with limit blocks 121. In this embodiment, there are six limit blocks 121, but four, five, or more limit blocks can also be provided. These limit blocks 121 are positioned around the mounting location of the circuit board 420, with at least one limit block 121 provided on each side of the circuit board 420. These limit blocks 121 abut against each side of the circuit board 420 to circumferentially limit the circuit board 420. In this embodiment, there are two hooks 122, located on the upper and lower sides of the circuit board 420. These hooks 122 are used to prevent the circuit board 420 from falling out of its mounting location. By providing a first groove 110 on the housing 100, providing a latching slot 111 in the first groove 110, and providing a latching buckle 411 on the panel 410, the panel 410 can be securely mounted on the housing 100. By providing a second groove 120 in the first groove 110, and providing a stopper 121 and a latching hook 122 on the second groove 120, the circuit board 420 can be securely mounted.

[0040] The reciprocating cutting device of the present invention also includes a battery pack 600, which is electrically connected to the circuit board 420 and the drive element 200. A spring 412 is provided on the panel 410, and a contact 421 is provided on the circuit board 420. The spring 412 can move slightly relative to the panel 410, contacting or separating with the contact 421. There are two springs 412 and two contacts 421, each of which is rotationally symmetrical about the midpoint of the line connecting the two contacts 421.

[0041] It should be noted that in this embodiment, the switch is configured as a push-type switch. Two springs 412 are provided on the panel 410, corresponding to two contacts 421 on the circuit board 420. When one contact 421 is triggered, the battery pack 600 supplies power to the drive motor, starting the jig saw. When the other contact 421 is triggered, the battery pack 600 stops supplying power to the drive motor, stopping the jig saw. The push-type switch, in which the springs 412 and contacts 421 make contact, is more convenient for the user to operate while holding the housing 100, compared to a sliding switch.

[0042] Preferably, the first switch assembly 400 further includes a baffle 430, which is disposed above the second groove 120. The baffle 430 has two ends disposed on either side of the second groove 120 and is disposed in the first groove 110. A slot 413 is provided on the panel 410, and a column 414 is provided on the side of the panel 410 adjacent to the housing 100. The baffle 430 includes a bump 431 and a through-hole 432. The bump 431 is inserted into the slot 413, and the column 414 is inserted into the housing 100 through the through-hole 432. The provision of the baffle 430 ensures a secure installation of the circuit board 420 and further stabilizes the connection between the panel 410 and the housing 100.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
