Embodiment 1

[0022] like figure 1 , figure 2 As shown, a lever type drilling device includes a fixed handle 1 with a cavity structure, a sliding rod 2 that is slidably arranged in the fixed handle 1 through the upper and lower end surface openings of the fixed handle 1, and a drill needle that is arranged at the bottom of the sliding rod 2. 3. The movable handle 4 hinged on the fixed handle 1, the support rod 5 fixed on the lower end of the fixed handle 1 and the adjustment seat 6 connected with the support rod 5; one side of the fixed handle 1 is completely open, and also includes a Chuck 7 on 2, one end of movable handle 4 is connected with chuck 7, and the other end runs through the side opening of fixed handle 1 and is located outside fixed handle 1; position spring 8; the adjusting seat 6 includes a base 9, a cover 10 hingedly connected to both sides of the upper surface of the base 9 respectively, the side of the cover 10 has a semicircular groove, and the semicircular grooves prov...

Embodiment 2

[0025] This embodiment is on the basis of embodiment 1, as image 3 As shown, retaining rings 19 are evenly distributed on the bottom rod 11 from bottom to top along the axis direction of the bottom rod 11 , and the diameter of the retaining rings 19 is larger than that of the bottom rod 11 .

[0026] When it is necessary to adjust the distance between the material to be punched and the drill pin 3, the cover 10 hinged on both sides of the upper surface of the base 9 is opened, and the bottom rod 11 is placed in the base 9. When the bottom rod 11 reaches the During proper position, cover 10 on both sides is covered, because back-up ring 19 diameters are greater than bottom rod 11 diameters, the position of bottom rod 11 will be fixed. The first pull rod A15 and the second pull rod A16 support one of the cover 10 when the cover 10 is opened, and the first pull rod B17 and second pull rod B18 support the other cover 10 . When the cover 10 on both sides needs to be closed, the s...

Embodiment 3

[0028] On the basis of Embodiment 1, this embodiment also includes a taper head 20 fixed at the lower end of the slide rod 2 through screw connection, and the drill needle 3 is fixed at the bottom of the taper head 20 . It also includes a handle 21 fixed on the side surface of the cone head 20 .

[0029] When the material to be punched is thick or the strength of the hand is difficult to complete the hole, while the above operation is performed, rotate the handle 21 with the other hand, and the drill needle 3 will move up and down and act on the material to be punched again, thereby assisting Finish punching.

Abstract

The invention discloses a lever drilling device. The lever drilling device comprises a fixed handle with a cavity structure, a slide rod slidingly arranged in the fixed handle by respectively penetrating through openings on the upper and lower end surfaces of the fixed handle, a drilling needle arranged at the bottom of the slide rod, a movable handle hinged to the fixed handle, a support rod fixed at the lower end of the fixed handle, and an adjusting base connected with the support rod; and one side of the fixed handle is totally opened. The lever drilling device further comprises a chuck fixed on the slide rod; and one end of the movable handle is connected with the chuck, and the other end penetrates through the opening on one side of the fixed handle and is positioned out of the fixed handle. The lever drilling device further comprises a limiting spring connected with the fixed handle by one end and connected with the movable handle at the other end; the adjusting base includes a base, and stop covers respectively hinged to two side edges of the upper surface of the base; semicircular grooves are formed in the side surfaces of the stop covers; and the semicircular grooves formed in the side surfaces of the two stop covers form a circular cavity. The lever drilling device further comprises a bottom rod slidingly arranged in the circular cavity. The lever drilling device is simple in structure and better in punching effect.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a lever type drilling device. Background technique [0002] At present, punching is done by using punching pliers. The punching pliers are composed of a handle, a punching head, a pressing sheet, and a hole seat. The punching head is connected to one handle, the hole seat is connected to the other handle, and the handles on both sides Riveted together by rivets, the cross-sectional shape of the punching head is arbitrary, the pressing piece and the hole seat are provided with holes corresponding to the shape of the punching head, when the handle is held, the punching head can pass through the pressing piece and the hole seat , the punching action is completed by impacting the punching head on the pressing sheet and the hole seat. The structure of the traditional punching device is not only complicated, but also difficult to completely penetrate the plate when encountering a thicker plate. ...
