For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The embodiment of the utility model provides a pusher as an auxiliary device of a cutting device, especially for some wooden materials. During the shaping process of a table saw, the risk of the original direct manual operation is avoided and the pusher can be applied to cutting at various angles.

[0048] Combine the following Figure 1-Figure 12 The technical solution provided by the utility model is described in more detail.

[0049] like Figure 1-Figure 5As shown, the pusher provided by the utility model includes a bracket 1, a fixed pressing part 2, a movable pressing part 3 and a locking assembly 4, wherein: the fixed pressing part 2 is fixed to the bottom of the bracket 1, a shaft 5 is fixed to the bottom of the bracket 1, the movable pressing part 3 is slidably connected with the shaft 5, the fixed pressing part 2 and the movable pressing part 3 can be pressed on the upper part of the material, and the friction force is used to drive the material to move; the locking assembly 4 is connected to the movable pressing part 3, and can lock the movable pressing part 3 on the shaft 5, and the locking assembly 4 is opened, and the movable pressing part 3 can slide along the shaft 5, so as to adjust the distance between it and the fixed pressing part 2.

[0050] Among them, see Figure 1 As shown, the pusher of this embodiment, the fixed pressing part 2 and the movable pressing part 3 can be pressed on the upper part of the material, and the friction force is used to drive the material to move. The handheld bracket 1 pushes the bracket 1, so as to realize the loading and unloading of the wood 10, avoiding the direct contact between the operator's hands and the wood 10, and reducing the safety risk; the bottom of the fixed pressing part 2 and the movable pressing part 3 are provided with anti-slip protrusion structures, such as anti-slip grooves, anti-slip teeth and other structures, so as to increase the friction between the pusher and the wood 10.

[0051] join Figure 2 As shown, for different widths a of the wood 10, the locking assembly 4 is opened, and the movable pressing part 3 can slide along the shaft 5, thereby adjusting the distance between it and the fixed pressing part 2, so as to adapt to the widths of different materials. For wood 10 with a smaller width, the wood 10 can be directly moved by the fixed pressing part 2 on one side. For wood 10 with a larger width, the wood 10 can be moved by both the fixed pressing part 2 and the movable pressing part 3, thereby increasing the contact area between the wood 10 and the pusher, thereby increasing the friction.

[0052] The lock assembly 4 is pressed, and the position of the movable pressing part 3 is fixed. When the pressing wood 10 is placed, the movable pressing part 3 moves along the shaft 5 .

[0053] As an alternative embodiment, see Figure 1 As shown, a handle 8 is provided on the upper portion of the bracket 1 .

[0054] The user holds the handle 8 to push the pusher, thereby pushing the wood 10 .

[0055] As an optional embodiment, the number of the fixed pressing parts 2 is one or more than two, see Figure 1 As shown, in this embodiment, when the number of the fixed pressing parts 2 is two, the fixed pressing parts 2 are distributed on both sides of the movable pressing part 3 .

[0056] In this embodiment, for wood 10 with different widths a, only one fixed pressing part 2 can be used to press down the wood 10, or one fixed pressing part 2 and a movable pressing part 3 can be used to press down the wood 10 (such as Figure 2), or using two fixed pressing parts 2 and one movable pressing part 3 to press down the wood 10, the friction between the pusher and the wood 10 can be increased as much as possible according to the width a of different wood 10, thereby facilitating the feeding and withdrawing of the wood 10.

[0057] This embodiment provides a specific implementation of a locking assembly 4, which can fix the movable pressing portion 3 on the shaft 5 and enable the movable pressing portion 3 to slide along the shaft 5:

[0058] Combination Figure 1 and Figure 3 As shown, the movable pressing part 3 is provided with a connected through hole 31 and a mounting hole 32, and the shaft body 5 passes through the through hole 31; the lock assembly 4 includes a lock handle 41 and a clamping block 42, wherein: the lock handle 41 is rotatably connected to the opposite sides of the through hole 31, and the clamping block 42 is located in the mounting hole 32, see Figure 4 , press the lock handle 41, the block 42 can be locked with the shaft 5 under the push of the lock handle 41; see Figure 5 When the lock handle 41 is rotated upward, the block 42 can be separated from the shaft body 5. Figure 4 and Figure 5 As shown, the block 42 includes an arcuate concave side 421 , which matches the outer contour of the shaft body 5 , and is located on a side of the block 42 that is away from the lock handle 41 .

[0059] When the lock handle 41 of the lock assembly 4 of this embodiment is pressed downward, the lock handle 41 can push the blocking block 42 to move toward the shaft body 5 and engage with the shaft body 5. After the blocking block 42 is engaged with the shaft body 5, the shaft body 5, the lock assembly 4, and the movable pressing portion are relatively fixed, and the movable pressing portion cannot continue to move along the shaft body 5.

[0060] As an alternative embodiment, see Figure 4 and Figure 5 As shown, the locking handle 41 includes a rotating part, which is rotatably connected to the movable pressing part 3, and the outer periphery of the rotating part includes a yielding arc side 411 and a pushing arc side 412 connected to each other, wherein: the distance between the pushing arc side 412 and the axis of the rotating part is greater than the distance between the yielding arc side 411 and the axis of the rotating part, and when the locking handle 41 is pressed, the pushing arc side 412 can push the clamping block 42 to move toward the shaft body 5 and clamp with the shaft body 5; when the locking handle 41 is rotated upward, the yielding arc side 411 rotates to the side of the shaft body 5, and the clamping block 42 can be separated from the shaft body 5.

[0061] See also Figure 4 As shown, when the lock handle 41 is pressed downward, the push arc side 412 and the block 42 abut against each other, pushing the block 42 to move toward the side of the shaft body 5, and the block 42 and the shaft body 5 are clamped and fixed to each other. At this time, the shaft body 5, the locking assembly 4, and the movable pressing part are relatively fixed, and the movable pressing part cannot continue to move along the shaft body 5.

[0062] See also Figure 5 As shown, the locking handle 41 is lifted upward and rotated, the pushing arc side 412 is separated from the block 42, and the giving way arc side 411 is rotated to the side of the shaft body 5. Since the distance between the pushing arc side 412 and the axis of the rotating part is greater than the distance between the giving way arc side 411 and the axis of the rotating part, the giving way arc side 411 cannot push the block 42 to engage with the shaft body 5 at this time, and the block 42 loses the external pushing force and cannot be fixed to the shaft body 5. At this time, the movable pressing part 3 can move along the shaft body 5, thereby adjusting the distance between the movable pressing part 3 and the fixed pressing part 2.

[0063] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the pusher also includes a support frame 6, which is connected to the bracket 1. The support frame 6 is an L-shaped frame structure and is used to be supported on a table.

[0064] The support frame 6 is used to support the table surface to improve the stability of the structure. The operator holds the handle 8 to make the pusher drive the wood 10 to move.

[0065] See also Figure 1 and Figure 2 As shown, there is a clearance groove 11 on the side of one of the fixed pressing parts, and the lower part and the side part of the clearance groove 11 are open structures. The clearance groove 11 is used to prevent the fixed pressing part 2 from interfering with the saw blade.

[0066] When it is necessary to cut thinner wood, the support frame 6 is disassembled, and the fixed pressing part 2 is pressed on the wood. The bracket is against the backrest position of the circular saw, and the saw blade is located in the give way groove. It can cut wood that is thinner than the width of the fixed pressing part 2, which is suitable for cutting thinner wood.

[0067] See also Figure 2 As shown, different heights h of wood 10 require different support heights.

[0068] In order to adapt the pusher to the height of the wood 10 of different heights h, see Figure 7 As shown, a one-way ratchet 61 is provided on the vertical section of the support frame 6, see Figure 6 and Figure 8 As shown, the side of the bracket 1 is provided with a limit tooth 92, which can engage with the one-way ratchet 61; by pulling the support frame 6 downward, the distance that the bottom end of the support frame 6 protrudes from the fixed pressing part 2 can be adjusted, thereby adjusting the support height.

[0069] In this embodiment, the bottom end of the support frame 6 protrudes from the fixed pressing part 2 at an adjustable distance, thereby adjusting the support height, thereby adapting to wood 10 of different heights h, improving the use range of the pusher, and ensuring that the support frame 6 can be supported on the table.

[0070] As an alternative embodiment, see Figure 6-Figure 12 As shown, the pusher of this embodiment also includes a clutch button assembly 7, which enables the limit tooth 92 and the one-way ratchet 61 to have an engaged state and a disengaged state, wherein: when in the engaged state, the support frame 6 can move downward in the vertical direction to adjust the support height; when in the disengaged state, the limit tooth 92 is separated from the one-way ratchet 61, and the support frame 6 can be removed from the bracket 1.

[0071] The clutch button assembly 7 is pressed downward, and the clutch button assembly 7 causes the limiting teeth 92 and the one-way ratchet teeth 61 to be in a separated state. The limiting teeth 92 are separated from the one-way ratchet teeth 61, and the support frame 6 can be taken out from the bracket 1.

[0072] When the clutch button assembly 7 is not pressed, the distance of the bottom end of the support frame 6 protruding from the fixed pressing part 2 can be adjusted only when the support frame 6 is pulled downward, thereby adjusting the support height. The support frame 6 cannot be pulled upward, so that the support frame 6 is supported on the table, and when the fixed pressing part 2 and the movable pressing part 3 are pressed down on the wood 10, the stability of the pusher structure is ensured to prevent relative displacement between the support frame 6 and the bracket 1.

[0073] As an alternative embodiment, see Figure 6 and Figure 8 As shown, the bracket 1 is provided with an assembly groove 91 and a shell 90, a rotating shaft 93 is rotatably connected in the assembly groove 91, a matching convex shaft 94 is fixedly connected to the rotating shaft 93, a limiting tooth 92 is fixed on the rotating shaft 93, and the shell 90 is fixedly connected to the opening side of the assembly groove 91, and an opening 901 is provided on the shell 90; see Figure 8-Figure 12 As shown, the clutch button assembly 7 includes a button rod 71 , the upper portion of which protrudes from the housing 90 , and a clearance groove 72 is provided at the lower portion of the button rod 71 , which is recessed in a direction away from the mating convex shaft 94 .

[0074] See also Figure 8-Figure 10 As shown, when in the meshing state, the mating convex shaft 94 is located in the clearance groove 72, and the limiting tooth 92 extends out of the opening 901 and meshes with the one-way ratchet 61; see Fig.11 and Fig.12 As shown, the button rod 71 is pressed downward to allow the positioning groove 72 to disengage from the mating convex shaft 94, and the remaining portion of the button rod 71 pushes the mating convex shaft 94 to rotate in a direction away from the one-way ratchet 61, thereby causing the limiting tooth 92 to retract into the assembly groove 91 and separate from the one-way ratchet 61.

[0075] A return spring can be fixed in the assembly groove 91, and the return spring abuts against the mating convex shaft 94. When the external force pressing the button rod 71 is removed, the mating convex shaft 94 can return to its original position under the action of the return spring, so that the limiting tooth 92 extends out of the opening 901 again. Figure 6 As shown, the engagement between the limiting tooth 92 and the one-way ratchet tooth 61 is achieved, as shown in FIG. Fig.10 shown.

[0076] See also Figure 8 , Fig. 9 and Fig.10 As shown, when the key rod 71 is not pressed, the clearance groove 72 of the key rod 71 cooperates with the mating convex shaft 94, see Figure 6 As shown, at this time, the limiting tooth 92 extends out of the opening 901, and the limiting tooth 92 can mesh with the one-way ratchet tooth 61. Fig.10 As shown, at this time, the support height can be adjusted only when the support frame 6 is pulled downward, and the support height cannot be adjusted when the support frame 6 is pulled upward.

[0077] See also Fig.11 As shown, the button rod 71 is pressed downward to move the positioning groove 72 downward. The button rod 71 pushes the mating convex shaft 94 to rotate around the rotating shaft 93. The limiting tooth 92 moves in a direction away from the one-way ratchet 61. The limiting tooth 92 cannot engage with the one-way ratchet 61. At this time, the support frame 6 can be removed from the bracket 1.

[0078] The support frame 6 structure in this embodiment can adjust the support height according to the different heights of the wood 10, so that the support frame 6 can always be supported on the table surface to prevent the overall rollover and ensure the stability of the structure.
