Description

Technical Field

[0001] The present application relates to the technical field of three-in-one hole punchers, and specifically to a new type of woodworking hole locator. Background Art

[0002] The three-in-one punch is a tool widely used in woodworking, metalworking and other material processing fields. It combines multiple functions such as drilling, measuring and processing in one, greatly improving work efficiency and processing accuracy.

[0003] The eccentric wheel hole on the side of the existing three-in-one punch is prone to deviation. If you do not pay attention to keeping the electric drill perpendicular to the plate when drilling, it is easy for the hole position to deviate, causing unnecessary losses. In addition, the extension rod generally cannot be upgraded or extended. When longer-distance positioning is required, a longer extension rod needs to be replaced.

[0004] Therefore, the present application provides a novel woodworking punching locator to solve the above problems. Utility Model Content

[0005] The present application provides a new type of woodworking hole locator, which aims to solve the problem that the eccentric wheel holes on the side of the existing three-in-one hole punch are prone to deviation as mentioned in the background technology. If the hand drill is not kept perpendicular to the board during drilling, the hole position may easily deviate, causing unnecessary losses.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a novel woodworking hole locator, comprising a center plate and an eccentric wheel drill sleeve disposed on the center plate, a slider disposed on the center plate, an extension rod disposed at one end of the slider, a positioning block sleeved on the extension rod, a clamping plate mounted on the end of the center plate away from the eccentric wheel drill sleeve, and a quick clamp disposed on the clamping plate;

[0007] A hole opener is movably connected to the eccentric drill sleeve, and the outer sleeve of the hole opener is provided with a limiting ring. A second bearing is provided at the inner groove of the eccentric drill sleeve, and a gasket and a first bearing intersecting with the gasket are provided at the end of the second bearing away from the center plate. A retaining spring is provided on the side of the first bearing away from the gasket. The hole opener is interspersed with the first bearing, the gasket and the second bearing in sequence and fixed by the retaining spring. The two bearings and the gasket arranged between the two bearings are superimposed to increase the stability of the hole opener, and slots are opened on both sides of the eccentric drill sleeve to facilitate chip removal. When the hole opener is opening a hole, the hole opener handle can effectively limit the swing of the hole opener through the bearing, thereby ensuring that the hole opener is perpendicular to the plate and the position of the hole opened by the hole opener is accurate. The slots on both sides of the eccentric drill sleeve can also discharge the generated debris in time, making the hole opening smoother.

[0008] Preferably, the eccentric drill sleeve is provided with a chip removal opening.

[0009] Preferably, a threaded head is provided at one end of the extension rod, and an internal threaded groove is provided at the end of the extension rod away from the threaded head. The extension rod has a fixed threaded head at one end and an internal threaded groove matching the threaded head at the other end. In this way, it can be extended by splicing. When a farther positioning is required, it can be extended by splicing and can be dismantled when not in use, which is more convenient and saves unnecessary expenses.

[0010] Preferably, the extension rod and the slider are threadedly connected via a threaded head.

[0011] Preferably, a plurality of quick-release slots are equidistantly provided on the center plate.

[0012] Preferably, the splint and the center plate are interlaced through hand screw threads.

[0013] This drilling locator redesigns the original eccentric wheel drill sleeve to fix the hole opener through a bearing and opens a chip removal port, which can effectively solve the deviation that occurs during side drilling. At the same time, the extension rod has a fixed threaded head at one end and an internal thread groove that matches the threaded head at the other end, so that it can be extended by splicing. When farther positioning is required, extension can be achieved by splicing.

[0014] The punching locator adopts a transverse semi-encircled quick-release slot on the center plate, so that the splint can be fixed by hand-tightening screws, thereby preventing the splint from falling. BRIEF DESCRIPTION OF THE DRAWINGS
