Description

technical field

[0001] The invention relates to the technical field of punching instruments, in particular to a drilling tool piercing and punching device. Background technique

[0002] Generally, most of the hole openers in the prior art commonly used in daily life adopt a hinge structure, such as the hole opener for paper pages adopts the hinge form, and the belt belt hole opener adopts the form of hand-held pliers. The torque of this type of hole saw is mostly based on the lever principle of the body design to realize the hole opening action. Its short moment arm and small torque can provide limited hole opening force, and in many cases it cannot meet the needs of hole opening, or even complete the hole opening action, and cannot completely open the hole. Contents of the invention

[0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a drilling tool piercing and punching device.

[0004] The technical solution ...

Examples

Embodiment Construction

[0047] Below in conjunction with accompanying drawing, the drilling tool piercing device of the present invention is described in detail below.

[0048] As shown in the accompanying drawings, the structure of the drilling drill of the present invention includes a base 1 and a support column 2,

[0049] The base 1 is set horizontally, the support column 2 is vertical to the base and fixedly connected to the center of the base, the lower section of the support column 2 is set as a solid cylindrical section 3 with a circular cross section,

[0050] The solid cylindrical section 3 of the support column is pierced with a lower receiving plate 4, and a lower rotating bearing 5 is arranged between the hole wall of the central plate hole of the lower receiving plate 4 and the outer periphery of the solid cylindrical section of the supporting column,

[0051] On the disk surface of the lower receiving plate 4, there are a circle of through holes 6 arranged circularly with the center of...
