A reciprocating saw with an adjustable base plate

Abstract

This utility model relates to a reciprocating saw with an adjustable base plate, including a housing assembly. A fixed base plate is located at the lower end of the housing assembly, and an adjustable base plate is located inside the fixed base plate. A track groove is formed at the lower end of the inner side of the adjustable base plate. A locking shaft assembly is located at the upper end of the adjustable base plate and the fixed base plate. One end of the locking shaft assembly extends to the outside of the housing assembly and is fixedly fitted with a locking button. The other end of the locking shaft assembly extends to the outside of the housing assembly and is fixedly fitted with a releasing button. The locking shaft assembly includes a pivot, and a boss shaft is fixedly fitted to the lower side of the pivot surface. A limit groove is formed on the surface of the pivot near the edge of the boss shaft. In this reciprocating saw with an adjustable base plate, when the adjustable base plate is locked, external force applied to the adjustable base plate is transmitted to the boss shaft. At this time, the shear force on the ribs of the adjustable base plate is sufficient due to the thickness and width of the ribs, allowing them to withstand a large force and preventing the locking state from failing.

Description

Technical Field

[0001] This utility model relates to the field of reciprocating saw technology, specifically a reciprocating saw with an adjustable base plate. Background Technology

[0002] A reciprocating saw is an electric tool that cuts by rapidly reciprocating the saw blade. Its core feature is that the saw blade moves back and forth at high speed in a straight line to cut. It consists of important components such as a housing, motor, transmission mechanism, blade lifting mechanism, saw blade, and switch. The motor drives the crankshaft and connecting rod to make the saw blade move in a linear reciprocating motion, cutting metal sheets, pipes, profiles, wood, and non-metallic materials. The practical value of the reciprocating saw is mainly reflected in three core areas: high-efficiency cutting, multi-material adaptability, and industrial automation advantages. By changing the saw blade and setting parameters, it can seamlessly switch between cutting wood, MDF, metal profiles, composite materials, etc., adapting to the needs of the furniture, building materials, and packaging industries.

[0003] However, in actual use, reciprocating saws can adjust the extension length of the base plate to meet different working conditions. The structure for adjusting the base plate length is mainly based on the front and rear locking buttons plus spring plates. The spring plates are pressed into the groove of the fixed base plate by the locking button shaft to lock the base plate. Due to structural limitations, the spring plates are relatively thin and are easy to break during use, thus causing failure. Based on this, a reciprocating saw with an adjustable base plate is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reciprocating saw with an adjustable base plate, which has the advantages of convenient operation and improved stability of the locking state. It solves the problem that the locking pin shaft presses the spring piece into the groove of the fixed base plate to lock the base plate, but due to structural limitations, the spring piece is relatively thin and easily breaks during use, leading to failure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reciprocating saw with an adjustable base plate, comprising a housing assembly, a fixed base plate being provided at the lower end of the interior of the housing assembly, an adjustable base plate being provided on the inner side of the fixed base plate, a track groove being provided at the lower end of the inner side of the adjustable base plate, a locking shaft assembly being provided at the upper end of the adjustable base plate and the fixed base plate, one end of the locking shaft assembly extending to the outer side of the housing assembly and a locking button being fixedly installed thereon, and the other end of the locking shaft assembly extending to the outer side of the housing assembly and a releasing button being fixedly installed thereon;

[0006] The locking shaft assembly includes a pivot, a boss shaft is fixedly mounted on the lower side of the pivot surface, and a limit groove is formed on the surface of the pivot on the side of the boss shaft.

[0007] Furthermore, a chuck is provided at the right end of the housing assembly, and a reciprocating saw blade is connected to the right end of the chuck.

[0008] Furthermore, the adjustable base plate is slidably connected to the fixed base plate, the surface of the pivot is slidably connected to the fixed base plate, the surface of the pivot is slidably connected to the adjustable base plate, and a protruding plate is provided on the upper side of the fixed base plate.

[0009] Furthermore, the housing assembly includes a left housing and a right housing, which are fixedly connected by bolts. A fixed base plate is fixedly connected to the left housing and the fixed base plate is fixedly connected to the right housing. Both the left and right housings have button slots.

[0010] Furthermore, the locking button engages with the button slot on the left housing, and the releasing button engages with the button slot on the right housing.

[0011] Furthermore, the track groove includes a first track and a second track, the boss shaft is slidably connected to the first track, and the boss shaft is engaged with the second track.

[0012] Furthermore, the second track includes grooves and ribs, with the ribs being evenly spaced and the grooves and ribs being staggered.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The reciprocating saw with an adjustable base plate eliminates the spring mechanism, allowing the boss shaft to be positioned within the straight groove of the adjustable base plate. This allows the adjustable base plate to move freely. When the locking button is in the locking position, the boss shaft on the locking button is positioned within the groove of the adjustable base plate. Thus, the adjustable base plate is immobilized due to the limitation imposed by the boss shaft. At this time, the boss shaft applies force to the raised ribs of the adjustable base plate, and the force of the raised ribs is sufficient to resist the boss force. When the adjustable base plate is locked, external forces applied to the adjustable base plate are transmitted to the boss shaft. At this time, the raised ribs of the adjustable base plate experience shear force. The thickness and width of the raised ribs are large enough to withstand a large force, thus preventing the locking state from failing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This embodiment of a reciprocating saw with an adjustable base plate includes a housing assembly. The housing assembly has a fixed base plate 1 at its lower interior end, an adjustable base plate 2 on its inner side, a track groove at its lower inner end, and a locking shaft assembly at the upper ends of the adjustable base plate 2 and the fixed base plate 1. One end of the locking shaft assembly extends to the outer side of the housing assembly and is fixedly fitted with a locking button 5, while the other end extends to the outer side of the housing assembly and is fixedly fitted with a releasing button 6. The locking shaft assembly includes a pivot 3, a boss shaft 4 fixedly fitted to the lower surface of the pivot 3, and a limit groove on the surface of the pivot 3 located on the side of the boss shaft 4.

[0024] In this embodiment, the spring clip structure is eliminated, and a boss shaft 4 is added to the pivot 3. A special track groove is made on the adjustable base plate 2. When the lock button is in the loose end, the boss shaft 4 on the lock button is located in the first track 11 of the adjustable base plate 2, so that the adjustable base plate 2 can move freely. When the lock button is in the locked end, the boss shaft 4 on the lock button is located in the second track of the adjustable base plate 2, so that the adjustable base plate 2 is in a state of immobility due to the limitation of the boss shaft 4. At this time, the boss shaft 4 applies a force to the rib 13 of the adjustable base plate 2, and the force of the rib 13 is sufficient to resist the boss force.

[0025] Please refer to the figure. Figures 1-6In this embodiment, a chuck 7 is provided at the right end of the housing assembly, and a reciprocating saw blade 8 is connected to the right end of the chuck 7. The adjustable base plate 2 is slidably connected to the fixed base plate 1, and the surface of the pivot 3 is slidably connected to the fixed base plate 1 and the adjustable base plate 2. A protruding plate is provided on the upper side of the fixed base plate 1. The housing assembly includes a left housing 9 and a right housing 10, which are fixedly connected by bolts. The fixed base plate 1 is fixedly connected to the left housing 9. Plate 1 is fixedly connected to the right housing 10. Both the left housing 9 and the right housing 10 are provided with button slots. Locking button 5 is engaged with the button slot of the left housing 9, and releasing button 6 is engaged with the button slot of the right housing 10. The track groove includes a first track 11 and a second track. Boss shaft 4 is slidably connected to the first track 11 and engaged with the second track. The second track includes grooves 12 and ribs 13. The ribs 13 are evenly distributed, and the grooves 12 and ribs 13 are staggered.

[0026] It should be noted that the fixed base plate 1 can be fixed to the housing with screws, and the adjustable base plate 2 can move back and forth along the fixed base plate 1. The adjustable base plate 2 includes a first track 11 and a second track. The second track includes multiple grooves 12 and ribs 13. The locking button 5 and the releasing button 6 are respectively installed on both sides of the pivot 3 and can move along the axial direction of the pivot 3. A convex plate is provided on one side of the adjustable base plate 2, which can cooperate with the limiting groove opened on the side of the boss shaft 4 to limit the movement distance of the pivot 3. The locking button 5 and the releasing button 6 are placed in the housing to prevent the pivot 3 from rotating on its own. The pivot 3 includes a boss shaft 4 welded to the pivot. Moving the pivot 3 can drive the boss shaft 4 to move on the adjustable base plate. When the first track 11 and the second track of 2 are switched, and the boss shaft 4 is located in the first track 11, the adjustable base plate 2 can move back and forth relative to the housing assembly (the release button 6 is pressed into the button slot, the protruding locking structure of the release button 6 is slightly away from the concave locking groove of the button slot of the right housing 10, and the protruding locking structure of the locking button 5 is tightly locked into the concave locking groove of the button slot of the left housing 9). When the boss shaft 4 is located in the groove 12 of the second track, the boss shaft 4 can block the adjustable base plate 2 (the locking button 5 is pressed into the button slot, the protruding locking structure of the locking button 5 is slightly away from the concave locking groove of the button slot of the left housing 9, and the protruding locking structure of the release button 6 is tightly locked into the concave locking groove of the button slot of the right housing 10), and the adjustable base plate 2 cannot be moved.

[0027] The working principle of the above embodiments is as follows:

[0028] In use, the adjustable base plate 2 can move back and forth along the fixed base plate 1. The locking button 5 and the releasing button 6 are respectively installed on both sides of the pivot 3 and can move along the axial direction of the pivot 3. The locking button 5 and the releasing button 6 are placed in the housing to prevent the pivot 3 from rotating on its own. The pivot 3 includes a boss shaft 4 welded to the pivot. By moving the pivot 3, the boss shaft 4 can be in the groove 12 of the first track 11 and the second track of the adjustable base plate 2. When the boss shaft 4 is in the first track 11 of the adjustable base plate 2, the adjustable base plate 2 can move back and forth relative to the housing assembly, thereby realizing the free movement of the adjustable base plate 2. When the boss shaft 4 is in the groove 12 of the second track of the adjustable base plate 2, the adjustable base plate 2 is blocked by the boss shaft 4 on the pivot 3, and the adjustable base plate 2 cannot be moved, thereby realizing the locked state of the adjustable base plate 2.
