Abstract
Description
Technical Field
[0001] This application relates to the field of power tool technology, and more specifically to a reciprocating saw with adjustable support components. Background Technology
[0002] A reciprocating saw is a common handheld power tool that uses a saw blade to cut by reciprocating linearly between two fixed points. To ensure accurate cutting, reciprocating saws are usually equipped with a support assembly. This assembly provides a stable support surface, ensuring the saw blade maintains linear movement during cutting and preventing the saw from wobbling and causing inaccurate cutting. The support assembly can also be adjusted in position according to different cutting needs, thereby achieving precise control over the cutting depth, cutting angle, and cutting position.
[0003] However, in traditional reciprocating saw designs, the support components are mostly connected by screws. This means that users need to use screwdrivers or wrenches to loosen the screws when adjusting the position of the support components, making the entire adjustment process very cumbersome. Furthermore, without carrying the necessary tools, users cannot adjust the position of the support components at all. Summary of the Invention
[0004] One objective of this application is to provide a reciprocating saw with adjustable support components to solve the problem that the adjustment steps of existing support components are cumbersome and require the use of auxiliary tools.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a reciprocating saw with adjustable support components, including a housing, a transmission component, and a support plate. The transmission component is disposed within an accommodating space inside the housing. The support plate is slidably connected to the transmission component. The support plate is provided with a plurality of locking holes spaced apart along the sliding direction of the support plate. The transmission component is provided with a vertically movable self-locking pin. The self-locking pin is connected to a push button. The push button can be operated to move the self-locking pin between a locked position and an unlocked position. When the self-locking pin is in the locked position, the self-locking pin cooperates with the locking holes to lock the support plate. When the self-locking pin is in the unlocked position, the self-locking pin separates from the locking holes to unlock the support plate.
[0006] As a preferred embodiment, the transmission assembly is provided with a first limiting part, and the housing is provided with a second limiting part. The first limiting part and the second limiting part are provided at a distance from each other, so that a sliding space is defined between the first limiting part and the second limiting part, and the support plate is horizontally slidably disposed in the sliding space.
[0007] As another preferred embodiment, the support plate includes a base plate, and side plates extending upward are provided on both sides of the base plate parallel to the sliding direction of the support plate. Each of the locking holes is arranged at intervals on the base plate along the sliding direction of the support plate. When the support plate is slidably disposed in the sliding space, the two side walls of the first limiting part are respectively attached to the two side plates, the bottom wall of the first limiting part is attached to the top surface of the base plate, and the top wall of the second limiting part is attached to the bottom surface of the base plate.
[0008] In a further preferred embodiment, the first limiting part is provided with a first receiving cavity with one end opening downwards, the self-locking pin is vertically movable and disposed in the first receiving cavity, the top end of the self-locking pin is provided with a first positioning pin, the outer diameter of the first positioning pin is smaller than the outer diameter of the self-locking pin, and a compression spring is sleeved on the first positioning pin to keep the self-locking pin and the locking hole in a fit relationship, one end of the compression spring abuts against the top wall of the first receiving cavity, and the other end of the compression spring abuts against the top end of the self-locking pin.
[0009] Furthermore, the second limiting part is provided with a locking groove, the position of which corresponds to the position of the self-locking pin. When the self-locking pin is in the locked position, the bottom end of the self-locking pin passes through the locking hole and is embedded in the locking groove.
[0010] Furthermore, a second positioning pin is provided at the bottom end of the self-locking pin, and a second accommodating cavity with one end opening upward is provided in the locking groove of the second limiting part. The second positioning pin is vertically movable and is provided in the second accommodating cavity. A positioning channel connecting adjacent locking holes is provided on the base plate. In the lateral direction perpendicular to the sliding direction of the support plate, the width of the positioning channel is less than the lateral dimension of the self-locking pin and greater than or equal to the lateral dimension of the second positioning pin.
[0011] Furthermore, the outer diameter of the second locating pin is smaller than the outer diameter of the self-locking pin.
[0012] Furthermore, the center distance between adjacent locking holes is greater than the diameter of the locking hole, and the positioning channel is a connecting groove between adjacent locking holes.
[0013] Furthermore, the center distance between adjacent locking holes is less than the diameter of the locking hole, and the positioning channel is a notch between adjacent locking holes.
[0014] Furthermore, the push button is movably disposed on the housing and connected to the self-locking pin, and the push button is located on the side of the housing.
[0015] Compared with the prior art, the beneficial effects of this application are as follows:
[0016] (1) When adjusting the position of the support plate, the user only needs to push the push button upward to release the lock on the support plate. After the position of the support plate is adjusted, the user can release the push button to restore the lock on the support plate. The entire adjustment process does not require the use of external auxiliary tools. The user can directly adjust the position of the support plate, saving time and effort.
[0017] (2) The support plate is movably set in the sliding space between the first limiting platform and the second limiting platform, and the support plate is attached to the first limiting platform and the second limiting platform, so as to ensure that the support plate can slide smoothly in the horizontal direction and avoid jamming during the adjustment of the position of the support plate.

Detailed Implementation
[0029] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0032] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0033] like Figure 1-10As shown, this application provides a reciprocating saw, which includes a housing 100, a motor, a transmission assembly 200, a saw blade (not shown), and a support assembly. The housing 100 defines a gripping part and a receiving space. The motor and the transmission assembly 200 are both disposed within the receiving space. The output shaft of the motor is connected to the transmission assembly 200, and the transmission assembly 200 is connected to the saw blade. Thus, the transmission assembly 200 can drive the saw blade to reciprocate along a first direction under the drive of the motor. The support assembly includes a support plate 300 and a guide plate 400 connected to and perpendicular to the support plate 300. The support plate 300 is slidably connected to the transmission assembly 200. Thus, the support plate 300 can slide and extend relative to the housing 100 along the first direction to adjust the position of the guide plate 400 relative to the saw blade, thereby realizing the adjustment of the cutting position of the reciprocating saw.
[0034] Furthermore, the support plate 300 includes a base plate 310, with upwardly extending side plates 320 on both sides of the base plate 310 parallel to the first direction. The base plate 310 has a plurality of locking holes 330 spaced apart along the first direction, with the locking holes 330 penetrating the base plate 310. A first limiting portion 210 is provided at the bottom end of the transmission assembly 200, and a second limiting portion 110 is provided within the accommodating space inside the housing 100. The first limiting portion 210 and the second limiting portion 110 are spaced apart from each other, defining a sliding space between them for accommodating the support plate 300. When the support plate 300 is slidably positioned within the sliding space, the two side walls of the first limiting portion 210 are respectively attached to the two side plates 320, the bottom wall of the first limiting portion 210 is attached to the top surface of the base plate 310, and the top wall of the second limiting portion 110 is attached to the bottom surface of the base plate 310. The two side walls of the first limiting part 210 are attached to the two side plates 320 to restrict the movement of the support plate 300 in the second direction perpendicular to the first direction; the bottom wall of the first limiting part 210 is attached to the top surface of the bottom plate 310, and the top wall of the second limiting part 110 is attached to the bottom surface of the bottom plate 310 to restrict the movement of the support plate 300 in the vertical direction, and also to ensure the smoothness of the support plate 300 when it slides along the first direction.
[0035] The bottom end of the first limiting part 210 is provided with a first receiving cavity 220 with one end open downward. A self-locking pin 510 is vertically movable in the first receiving cavity 220. The outer wall of the self-locking pin 510 fits against the inner wall of the first receiving cavity 220. The self-locking pin 510 is connected to a push button 600. The push button 600 is vertically movable on the housing 100 and is located on the side of the housing 100. The push button 600 can be moved up and down to drive the self-locking pin 510 to move up and down between a locked position and an unlocked position. When the self-locking pin 510 is in the locked position, the bottom end of the self-locking pin 510 engages with the locking hole 330 on the base plate 310 to lock the support plate 300, and the support plate 300 cannot slide along the first direction; when the self-locking pin 510 is in the unlocked position, the bottom end of the self-locking pin 510 separates from the locking hole 330 on the base plate 310, unlocks the support plate 300, and the support plate 300 can slide along the first direction.
[0036] Preferably, a first positioning pin 520 is provided at the top of the self-locking pin 510. The outer diameter of the first positioning pin 520 is smaller than the outer diameter of the self-locking pin 510. A compression spring 540 is sleeved on the first positioning pin 520 to keep the self-locking pin 510 and the locking hole 330 in a cooperating tendency. One end of the compression spring 540 abuts against the top wall of the first accommodating cavity 220, and the other end of the compression spring 540 abuts against the top of the self-locking pin 510. When the user pushes the push button 600 upwards, the push button 600 moves upwards, causing the self-locking pin 510 to move from the locked position to the unlocked position. The self-locking pin 510 separates from the locking hole 330 to unlock the support plate 300. The support plate 300 can slide along the first direction to adjust the position of the guide plate 400, and the compression spring 540 is compressed and deformed. When the user releases the push button 600, the compression spring 540 returns to its original deformation, moving the self-locking pin 510 from the unlocked position to the locked position. The self-locking pin 510 cooperates with the locking hole 330 to lock the support plate 300. The support plate 300 can no longer slide along the first direction to adjust the position of the guide plate 400, thus realizing the automatic locking of the support plate 300 by the self-locking pin 510.
[0037] It is worth mentioning that when the self-locking pin 510 is in the locked position, the compression spring 540 will also undergo a certain degree of compression deformation. This compression deformation will cause the compression spring 540 to apply a downward preload to the self-locking pin 510. When the force of the user pushing the push button 600 upward does not exceed the magnitude of the preload, the push button 600 will not move upward to drive the self-locking pin 510 from the locked position to the unlocked position. Only when the force of the user pushing the push button 600 upward exceeds the magnitude of the preload will the push button 600 move upward to drive the self-locking pin 510 from the locked position to the unlocked position. This can prevent the support plate 300 from being unlocked due to accidental contact with the push button 600, and improve the locking effect of the self-locking pin 510.
[0038] The second limiting part 110 is provided with a locking groove 120, the position of which corresponds to the position of the self-locking pin 510. When the self-locking pin 510 is in the locked position, the bottom end of the self-locking pin 510 is embedded in the locking groove 120, and the bottom end of the self-locking pin 510 cooperates with the locking groove 120. During the use of the reciprocating saw, the external force applied by the support plate 300 to the self-locking pin 510 is along the first direction. By placing the bottom end of the self-locking pin 510 in the locking groove 120, both the bottom end and the top end of the self-locking pin 510 have support points, which improves the structural strength of the self-locking pin 510 and prevents the self-locking pin 510 from breaking due to excessive external force applied by the support plate 300.
[0039] In some preferred embodiments, a second positioning pin 530 is also provided at the bottom end of the self-locking pin 510. The outer diameter of the second positioning pin 530 is smaller than the outer diameter of the self-locking pin 510. The second limiting part 110 is provided with a second receiving cavity 130 with one end opening upward in the locking groove 120. The shape of the second receiving cavity 130 is adapted to the shape of the second positioning pin 530. The second positioning pin 530 is vertically movable in the second receiving cavity 130. The outer wall of the second positioning pin 530 is attached to the inner wall of the second receiving cavity 130. A positioning channel 340 is provided on the bottom plate 310 to connect adjacent locking holes 330. The positioning channel 340 allows the second positioning pin 530 to pass through and move from one locking hole 330 to another adjacent locking hole 330. The arrangement of the first accommodating cavity 220 and the second accommodating cavity 130 causes the outer wall of the self-locking pin 510 to abut against the inner wall of the first accommodating cavity 220, and the outer wall of the second positioning pin 530 to abut against the inner wall of the second accommodating cavity 130. Thus, the first accommodating cavity 220 and the second accommodating cavity 130 can restrict the horizontal movement of the self-locking pin 510 and the second positioning pin 530, so that the self-locking pin 510 and the second positioning pin 530 can only move in the vertical direction. At the same time, it can also make the vertical movement of the self-locking pin 510 and the second positioning pin 530 smoother and more seamless, and prevent problems such as jamming during the movement.
[0040] In the reciprocating saw provided in this application, the adjustable working principle of the support component is to adjust the locking of the self-locking pin 510 with different locking holes 330 by moving the push button 600 up and down. Specifically, by moving the push button 600 upwards, the push button 600 causes the self-locking pin 510 and the second positioning pin 530 to move upwards. When the self-locking pin 510 moves to the unlocked position, the bottom surface of the self-locking pin 510 is higher than the base plate 310, and the second positioning pin 530 passes through the locking hole 330. At this time, the support plate 300 can move in the first direction, and the self-locking pin 510 and the second positioning pin 530 move in opposite directions relative to the support plate 300. The second positioning pin 530 can pass through the positioning channel 340. When the second positioning pin 530 moves to the target locking hole 330, the push button 600 is released. Under the action of the restoring force of the compression spring 540, the self-locking pin 510 drives the push button 600 to move downwards together. The self-locking pin 510 is inserted into the locking hole 330, and the movement stops when the self-locking pin 510 engages with the locking hole 330, thus completing the adjustment of the support plate 300.
[0041] It is worth mentioning that the width of the positioning channel 340 in the second direction is smaller than the diameter of the self-locking pin 510 but larger than the diameter of the second positioning pin 530. The smaller width of the positioning channel 340 in the second direction prevents the self-locking pin 510 from entering the positioning channel 340 or even the adjacent locking hole 330 when it engages with the locking hole 330, thus preventing the locking effect of the self-locking pin 510 on the support plate 300 from failing. The larger width of the positioning channel 340 in the second direction ensures that the second positioning pin 530 can pass through the positioning channel 340 during adjustment.
[0042] Optionally, when the center distance between adjacent locking holes 330 is greater than the diameter of the locking hole 330, the positioning channel 340 is implemented as a connecting slot between adjacent locking holes 330.
[0043] Optionally, when the center distance between adjacent locking holes 330 is less than the diameter of the locking hole 330, the positioning channel 340 is implemented as a gap between adjacent locking holes 330.

Those skilled in the art should understand that this application is not limited to the above embodiments.
