In addition, the blade 132a of the cutter 132 can extend into the notch 131a, so that the cutter 132 can cut the retainer 200 smoothly, and the phenomenon that the cutter 132 and the retainer 200 "slip" can be effectively avoided, that is, the cutter 132 cannot cut the retainer 200 can be avoided.

Some specific embodiments of the lancing device 100 of the present utility model are described below. For convenience of description, the left-right direction of fig. 1 is a first direction, and the up-down direction of fig. 1 is a second direction. The lancing device 100 of an embodiment of the present utility model includes a chassis 110, a drive assembly 120, and a cutter assembly 130.

In some embodiments, as shown in fig. 1 and 2, the driving member 120 includes a driving cylinder 121 and a driving part 122, the driving cylinder 121 being provided on the base 110, i.e., the driving cylinder 121 is fixed on the base 110. The driving part 122 is provided on the driving cylinder 121 movably in a first direction, and the driving cylinder 121 and the driving part 122 cooperate with each other to power the driving part 122. That is, the driving cylinder 121 may drive the driving part 122 to move in the first direction.

Alternatively, the driving member 120 is driven pneumatically. For example, the driving cylinder 121 is a cylinder.

In some embodiments, as shown in fig. 1 and 2, the cutter assembly 130 includes an abutment post 131 and a cutter 132, the abutment post 131 is disposed on the base 110, the abutment post 131 extends along the second direction, the cutter 132 is disposed on the driving portion 122, and the cutter 132 can abut against the abutment post 131 under the driving of the driving portion 122, so as to cut off the retainer ring 200. That is, the cutter 132 cuts the retainer ring 200 by generating a pressing force on the abutment post 131. Specifically, when the retainer ring 200 is sleeved on the abutment post 131, the driving portion 122 drives the cutter 132 to abut against the abutment post 131, so as to cut off the retainer ring 200.

Alternatively, the abutment post 131 may be a polygonal prism, a cylinder or a table post, or the like.

Specifically, when the cutter 132 cuts the retainer ring 200, the retainer ring 200 may slide under the compression of the cutter 132 and the abutment post 131 during the movement of the cutter 132, resulting in that the cutter 132 cannot smoothly cut the retainer ring 200. However, during the process of pressing the cutter 132 and the abutment post 131 against each other, the slit groove 131a can increase the friction force of the retainer ring 200, prevent the retainer ring 200 from sliding, and ensure that the cutter 132 can smoothly cut the retainer ring 200.

Alternatively, the groove width of the slit groove 131a is 1mm, and the depth of the slit groove 131a is 1mm.

In some embodiments, as shown in fig. 1 and 2, the extending direction of the blade 132a of the cutter 132 is orthogonal to the first direction, and an included angle is formed between the extending direction of the blade 132a of the cutter 132 and the second direction, and the included angle is greater than or equal to 0 degrees and less than 90 degrees, and the second direction is orthogonal to the first direction.

In some embodiments, as shown in fig. 1 and 2, the cutter holder 133 is rotatably disposed on the driving part 122, and an axial direction of the rotation shaft of the cutter holder 133 is parallel to the first direction.

Specifically, the extending direction of the blade 132a of the cutter 132 may be changed by rotating the cutter holder 133 on the driving part 122, that is, the extending direction of the blade 132a of the cutter 132 may be changed to form an angle with the second direction. At the same time, the extending direction of the notch groove 132a on the abutment post 132 is kept identical to the extending direction of the blade 132a of the cutter 132, ensuring that the blade 132a can be fitted with the notch groove 132 a. In some embodiments, as shown in fig. 1 and 2, the incision device 100 further includes a first stopper 140 and a second stopper 150, the first stopper 140 is disposed on the base 110, the second stopper 150 is disposed on the driving portion 122, the first stopper 140 is located between the second stopper 150 and the abutment post 132 in the first direction, and the second stopper 150 can abut on the first stopper 140 in the first direction to limit the size of the cutting edge 131a of the cutter 131 extending into the incision slot 132 a.

Specifically, in the process that the driving portion 122 drives the cutter 131 to move, the first limiting block 140 may limit the displacement of the second limiting block 150, so as to limit the size of the cutting edge 131a of the cutter 131 extending into the notch 132a, and avoid the excessive size of the cutting edge 131a of the cutter 131 extending into the notch 132a, so as to damage the cutting edge 131a of the cutter 131.

In some embodiments, as shown in fig. 1 and 2, the position of the first limiting block 140 in the first direction is adjustable.

In some embodiments, as shown in fig. 1 and 2, the position of the second stopper 150 in the first direction is adjustable.
