A stop block is fixedly sleeved on the middle part of the threaded section, the stop block divides the threaded section into an upper threaded section and a lower threaded section, the upper threaded section is screwed in the threaded hole of the drum, and the lower threaded section is screwed with an ejection plate of which the upper part is provided with a groove. A T-shaped pin is arranged between the ejection plate and the stop block, the tail part of the pin penetrates through a through hole in the stop block vertically, and the T-shaped head at the other end is clamped and connected into the groove of the ejection plate. The bottom surface of the drum is also provided with a through hole which is corresponding to the through hole in the stop block. The novel hole saw is simple in structure, the pin is added to the shaft rod and is used for connecting the shaft rod with the drum, the looseness of the drum is effectively avoided, the operation is simple, and the disassembly is convenient.
Description
Technical field
The utility model relates to a kind of hole saw.
Background technology
Present employed hole saw mainly is to be made of axostylus axostyle and the rotating cylinder that is rotatably connected on the axostylus axostyle, and the axostylus axostyle drive unit that is connected makes axostylus axostyle be subjected to the driving of drive unit and drives rotating cylinder synchronously and rotate, in order to workpiece sawings such as plank or metallic plate are gone out a circular hole; In practical operation, because rotating cylinder is rotatably connected in axostylus axostyle, and the thread segment that axostylus axostyle is connected with rotating cylinder is often shorter, therefore in the fast rotational process, rotating cylinder can occur becoming flexible with being connected of axostylus axostyle, even screwed out axostylus axostyle, production is brought inconvenience, even threaten operating personnel's safety.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of connection firm, can effectively avoid rotating cylinder to become flexible or screw out the novel hole saw of axostylus axostyle.
The purpose of this utility model is achieved by the following technical solution: mainly comprise an end face opening, bottom center offer a screwed hole rotating cylinder, the axostylus axostyle that a top is provided with thread segment; Described axostylus axostyle top is plugged with a drill bit; The middle part fixed cover of described thread segment is connected to a block; Described block is divided into epimere screw thread and hypomere screw thread two parts with thread segment, and wherein the epimere screw thread is rotatably connected in the screwed hole of described rotating cylinder, is connected with the push pedal that a top offers a groove on the hypomere screw thread; Be provided with T font pin between described push pedal and the block; The afterbody of described pin vertically passes the perforation that is opened on the described block, and other end T connector portion is connected in the groove of described push pedal; Also offer the through hole corresponding with the perforation on the described block on the described rotating cylinder bottom surface.
The bottom of described axostylus axostyle is for being used for connecting the joint of drive unit; On the described axostylus axostyle, the junction of thread segment and joint also is provided with a limiting plate.
The opening part edge of described rotating cylinder stack shell upper end is provided with sawtooth; Also offer on the described rotating cylinder stack shell for the chip-removal hole of getting rid of scrap.
Described pin is two; Described two pins are oppositely arranged centered by axostylus axostyle; Described perforation is two, and with the corresponding setting of described pin.
The beneficial effects of the utility model are: it simple in structure, and add pin at axostylus axostyle, and by pin axostylus axostyle is connected with rotating cylinder, effectively avoided rotating cylinder loosening, simple to operate, convenient disassembly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of axostylus axostyle described in the utility model.
Fig. 3 is the structural representation of rotating cylinder described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, 2, 3, mainly comprise an end face opening, bottom center offer a screwed hole 11 rotating cylinder 1, the axostylus axostyle 2 that a top is provided with thread segment; Described axostylus axostyle 2 tops are plugged with a drill bit 3; The middle part fixed cover of described thread segment is connected to a block 21; Described block 21 is divided into epimere screw thread 22 and hypomere screw thread 23 two parts with thread segment, and wherein epimere screw thread 22 is rotatably connected in the screwed hole 11 of described rotating cylinder 1, is connected with the push pedal 4 that a top offers a groove 5 on the hypomere screw thread 23; Be provided with T font pin 6 between described push pedal 4 and the block 21; The afterbody of described pin 6 vertically passes the perforation 24 that is opened on the described block 21, and other end T connector portion 7 is connected in the groove 5 of described push pedal 4; Also offer the through hole 12 corresponding with the perforation 24 on the described block 21 on described rotating cylinder 1 bottom surface; Rotating cylinder 1 and axostylus axostyle 2 are withstood by block 21 by after being threaded, and rotate push pedal 4 this moment, promotes pin 6 synchronously and upwards rise up in described perforation 24 and the through hole 12, make pin pin rotating cylinder.
The bottom of described axostylus axostyle 2 is for being used for connecting the joint 25 of drive unit; 2 upper and lower sections screw threads of described axostylus axostyle 23 also are provided with a limiting plate 26 with the junction of joint 25, when being rotated down push pedal, pin is down motion synchronously, prop up push pedal 4 to limiting plate 26, pin just breaks away from the through hole on the rotating cylinder, at this rotation rotating cylinder, rotating cylinder is unloaded from axostylus axostyle, and in the perforation on block still of pin one end this moment, can't break away from.
The opening part edge of described rotating cylinder 1 stack shell upper end is provided with sawtooth 13; Also offer on described rotating cylinder 1 stack shell for the chip-removal hole 14 of getting rid of scrap.
Described pin 6 is two; Described two pins 6 are oppositely arranged centered by axostylus axostyle 2; Described perforation 24 is two, and with described pin 6 corresponding settings.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
