According to the utility model, by arranging the toggle block 14, a user can press the toggle block 14 by hand to toggle the sliding component to move, so that the blade 3 can be driven to move conveniently. The setting of pressing the subassembly, when getting blade 3, the accessible presses the subassembly and presses installation lug 6, and then the mounting panel 5 of being convenient for moves down, so be convenient for take out of blade 3.

As shown in fig. 1 to 9, in some embodiments of the present invention, the pressing assembly includes a rotating plate 15 rotatably disposed on the toggle block 14, a connecting shaft 17 rotatably passing through the rotating plate 15, a knob 18 disposed at one end of the connecting shaft 17, and a pressing block 19 disposed at the other end of the connecting shaft 17; the knob 18 and the pressing block 19 are respectively located on both sides of the rotating plate 15; the pressing block 19 is tapered.

The working principle is as follows: when the blade 3 needs to be taken out, as shown in fig. 6, at this time, the rotating plate 15 is rotated out from the toggle block 14, at this time, the rotating plate 15 drives the pressing block 19 to move to the top of the mounting lug 6, at this time, the knob 18 can be pressed downward, and the knob 18 pushes the pressing block 19 to move downward through the connecting shaft 17 and presses the mounting lug 6 downward; because the horizontal position of blade 3 is unchangeable, so installation lug 6 separates with the through-hole of blade 3 after moving down, can pull blade 3 outward this moment, and blade 3 breaks away from sliding assembly can. Since the pressing block 19 is tapered, it is convenient for the through hole of the blade 3 to slide out of the pressing block 19. Optionally, the rotating plate 15 of the present embodiment is rotatably disposed on the dial block 14 through the rotating shaft 16, the dial block 14 is provided with an accommodating groove 20, and the pressing assembly can be accommodated through the accommodating groove 20.

As shown in fig. 1 to 9, in some embodiments of the present invention, the toggle block 14 is slidably connected to the limit baffle 13, and the toggle block 14 is provided with two opposite clamping grooves 21; the limit baffle 13 is provided with a clamping convex block 22 matched with the clamping groove 21, and the clamping convex block 22 is embedded into the clamping groove 21 in a sliding manner.

According to the utility model, the clamping groove 21 and the clamping convex block 22 are arranged, so that when the shifting block 14 is installed, the shifting block 14 can be placed on one side of the limiting baffle 13, the clamping groove 21 is aligned with the clamping convex block 22, one end of the clamping convex block 22 is embedded into the opening of the clamping groove 21, then the shifting block 14 is slid, and at the moment, the clamping convex block 22 is completely embedded into the clamping groove 21, so that the installation of the shifting block 14 is completed, and the shifting block 14 can conveniently slide along the limiting baffle 13.

As shown in fig. 1 to 9, in some embodiments of the present invention, the handle is provided with a limit rack 23 along the extending direction of the chute 2; the mounting plate 5 is provided with a limit protruding tooth 24 engaged with the limit rack 23, and the limit protruding tooth 24 is embedded in the limit rack 23.

According to the utility model, the limiting rack 23 is arranged, so that the limiting convex teeth 24 of the mounting plate 5 are embedded into the limiting rack 23 at the corresponding position of the mounting plate 5 to realize meshing clamping under the elastic action of the elastic member 7 of the mounting plate 5, the mounting plate 5 is prevented from sliding along the sliding chute 2, the sliding assembly is further prevented from sliding along the sliding chute 2, and the blade 3 is stable in position and cannot move and retract inwards when the blade 3 is used, so that the blade 3 is convenient to fix.

When the position of slide module in order to adjust blade 3 needs to be removed, can press down mounting panel 5, mounting panel 5 drives spacing dogtooth 24 and moves down and separate with spacing rack 23, loses the restriction of spacing rack 23 so, but mounting panel 5 and slide module free slip. After the mounting plate 5 slides to a proper position, the mounting plate 5 is released, and at the moment, under the action of the elastic force of the elastic piece 7, the limiting convex teeth 24 of the mounting plate 5 move upwards to be embedded into the limiting racks 23 at the corresponding positions of the mounting plate 5 at the moment to realize meshing clamping.
