[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides an aluminum wire machine cutter connector, such as Figure 1 , Figure 2 and Figure 3 As shown, the connector includes a mounting block 2 on the output end of the cutter moving mechanism 1, a receiving groove 21 for accommodating the cutter is provided at one end of the mounting block 2 away from the cutter moving mechanism 1, and a locking mechanism 3 for fixing the cutter in the receiving groove 21 is provided at one end of the mounting block 2 away from the cutter moving mechanism 1.

[0030] The locking mechanism 3 includes at least three clamping blocks 31 distributed in an annular array inside the receiving groove 21 and a sleeve 32 screwed on the mounting block 2 for driving the clamping block 31 to move radially along the receiving groove 21 .

[0031] The cross-sectional area of ​​the clamping block 31 at one end close to the cutter moving mechanism 1 gradually increases toward the cross-sectional area of ​​the clamping block 31 at one end away from the cutter moving mechanism 1 .

[0032] The cutter moving mechanism 1 includes a cylinder, a mounting block 2 fixedly mounted on one end of a piston rod close to the cutter, and a pressing block for pressing the cutter handle inside the mounting block 2. By setting the pressing block, when the cylinder drives the cutter to move downward to cut the aluminum wire, the pressing block provides support for the cutter, so that the cutter can cut the aluminum wire more stably.

[0033] When the cutter needs to be installed, the handle of the cutter is inserted into the receiving groove 21 on the mounting block 2, and the sleeve 32 is rotated. The sleeve 32 moves downward along the outer surface of the mounting block 2, and then the sleeve 32 squeezes the inclined surface on the clamping block 31, so that the clamping block 31 slides inward synchronously to clamp the handle of the cutter, so that the cutter is firmly installed on the movable end of the cutter moving mechanism 1, which is convenient for use. At the same time, through the arrangement of the sleeve 32 and the clamping block 31, the clamping block 31 is convenient for clamping cutters of different sizes.

[0034] Furthermore, in order to prevent the clamping block 31 from being easily deflected when sliding, Figure 4 and Figure 5 As shown, the mounting block 2 is provided with a slide groove for the clamping block 31 to slide, the slide groove is fixedly connected to the limit plate 11, and the clamping block 31 is provided with a limit groove 312 adapted to the limit plate 11.

[0035] When the sleeve 32 moves downward to squeeze the clamping block 31 , the limiting groove 312 on the clamping block 31 moves along the limiting plate 11 , and the limiting plate 11 cooperates with the limiting groove 312 to enable the clamping block 31 to slide stably on the mounting block 2 .

[0036] Furthermore, in order to improve the stability of the clamping block 31 when sliding and to facilitate the resetting of the clamping block 31 when removing the cutter, a sliding block 311 that slides inside the mounting block 2 is fixedly connected to the clamping block 31, and a resetting member 4 is provided inside the mounting block 2 for pushing the clamping block 31 to move away from the cutter.

[0037] When the clamping block 31 squeezes the cutter, the reset member 4 is squeezed. When the cutter needs to be replaced, the sleeve 32 is rotated to move the sleeve 32 upward to release the squeezing of the clamping block 31. The reset member 4 simultaneously releases the limit and pushes the sliding block 311 to slide in the direction away from the cutter, thereby pushing the clamping block 31 to reset through the reset member 4, remove the old cutter, and then take the new cutter and insert it into the accommodating groove 21. The sleeve 32 is rotated to move the sleeve 32 downward to squeeze the clamping block 31. The clamping blocks 31 are close to each other to clamp the cutter for easy use.

[0038] Furthermore, in order to facilitate the reset member 4 to push the clamping block 31 to reset, the reset member 4 includes a reset spring 41 with two ends respectively fixedly connected to the sliding block 311 and the mounting block 2 .

[0039] By disposing the return spring 41, when the cutter is removed, the return spring 41 simultaneously presses the sliding block 311 to return to its original position, which is convenient for use.

[0040] In order to increase the contact area between the clamping block 31 and the cutter, the side of the clamping block 31 close to the cutter has a curved surface adapted to the outer surface of the cutter.

[0041] By providing the arc surface on the clamping block 31, the contact area between the clamping block 31 and the cutter is increased, thereby increasing the friction force, making it difficult for the cutter to vibrate during use, thereby improving the use efficiency of the cutter.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
