Abstract
The invention provides a blade holder in order to solve the problems that the angle of an existing blade holder can not be adjusted conveniently, and the stability is poor because a blade is fixed by the utilization of a pinch plate and a sucker. The blade holder comprises a handle and a pressing folding assembly installed on the handle, wherein the pressing folding assembly is connected with a blade holding rod, a groove is formed in one end of the blade holding rod, and a jack screw is arranged on one side of the groove. The blade holder is used as a medical apparatus.
Description
Technical field:
The present invention relates to a kind of medical apparatus and instruments, a kind of blade drive rotaining device of specific design.
Background technology:
The scalpel of Shi Yonging is combined by blade and handle usually clinically, both are structure linearly generally, for some special operative sites, often needing blade and handle to be certain angle such as right angle, use existing scalpel to operate, generally all is to replace scalpel by tool holding blades such as pliers, because the blade both sides are comparatively smooth, clamp not strongly admittedly, be easy to make the blade landing, therefore bring very big inconvenience to medical work.
In order to address the above problem, Chinese patent 201220247058.2 discloses a kind of blade drive rotaining device, and following technical characterictic disclosed specifically: this blade drive rotaining device, comprise a handle bar, handle bar front end is provided with sucker, it is characterized in that: the handle bar is provided with a sliding sleeve, sliding sleeve is provided with hinged seat, and by hinged seat a curved bar is arranged fixedly, and the curved bar front end is provided with the buckle that can fasten with sucker, and the sliding sleeve front side is provided with spring.During use, by sucker that blade absorption is fixing earlier, rotate curved bar then, make buckle be buckled in the blade outside, buckle and sucker are tightly fixing with blade.This patent has realized that to a certain extent blade angle is adjustable, but the adjusting angle inconvenience, and the mode fixed blade poor stability of employing buckle and sucker.
Summary of the invention:
The objective of the invention is provides a kind of blade drive rotaining device at the problem of above-mentioned existence, can conveniently regulate the angle of blade, and adds and keep steady surely, and operation is reliable.
Above-mentioned purpose realizes by following technical scheme:
Blade drive rotaining device comprises handle and is installed in the Foldable assembly of pressing on the described handle, and the described Foldable assembly of pressing connects blade and adds and hold bar, and described blade adds the termination of holding bar and has a groove, and a side of described groove is provided with jackscrew.
Described blade drive rotaining device, the described Foldable assembly of pressing comprises adding with described blade and holds the bar internal gear one that is connected and the internal gear two that is connected with described handle, described internal gear one equates with the number of teeth and the tooth pitch of described internal gear two, above the described internal gear two button is installed, connect the external gear one that cooperates with described internal gear one and described internal gear two below the described button, mounting spring below the described button, below the described internal gear two lock nut is installed, have the external gear two that cooperates with described internal gear one and described internal gear two above the described lock nut, connect self-tapping screw below the described lock nut.
Beneficial effect:
Press button of the present invention and lock nut simultaneously with finger during use, make spring be in compressive state, make external gear one break away from internal gear one and internal gear two, at this moment the switching blade adds and holds bar and handle to suitable angle, release button and lock nut then, under the elastic force effect of spring, external gear one rebounds and internal gear one engagement, external gear two rebounds and internal gear two engagements, owing to be connected by self-tapping screw between external gear one and the external gear two, so at this moment external gear one is fixing with respect to external gear two, thereby make internal gear one fixing with internal gear two, connected blade adds holds bar and handle then is fixed on the angle of institute's switching, the back or do not need when folding of finishing using, and pressing button and lock nut are pulled handle head and handle afterbody directly and are got final product simultaneously.Can easily blade and cutter head be adjusted to suitable angle like this, and blade of the present invention adds and hold the rod end head and have a groove, a side of described groove is provided with jackscrew, and is by the jackscrew fixed blade, stable, reliable.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Fig. 2 is explosive view of the present invention.
