Abstract
The invention discloses a kind of lever switch to extend handle, it is related to switching appurtenance technical field, including extending lever, the one end for extending lever is fixedly connected with elastic u-shaped buckle, is fixedly connected with switch touch-control protrusion close to the lower surface of the extension lever of elastic u-shaped buckle；The end that pressing extends lever can make switch touch-control protrusion press root canal preparation machine switch, control root canal preparation machine switches on-off, therefore the original root canal preparation machine position of the switch can be extended to position usually accustomed to using through the invention, the hand-held root canal preparation machine that user can be stable always, which gently starts to refer to, can control root canal preparation machine switch；By lever principle, torque becomes larger after extension, is less than the power directly pressed at pre- standby host switch to the power that stress point at pre- standby host switch applies, makes equipment operator more labor-saving；Elastic u-shaped buckle can be quickly stuck at root canal preparation machine switch, be mounted and dismounted more convenient.
Description
Technical field
The present invention relates to switch appurtenance technical field, specifically a kind of lever switch extends handle.
Background technique
Root canal therapy is also known as endodontic treatment, is a kind of operation that pulp necrosis and tooth root infection are treated during dentist learns.It should
Operation remains tooth, thus complementary with tooth extraction.It performs the operation cumbersome, generally wants to go to a doctor and could complete for 2-4 times.Tooth intermediate void
Part include referred to as dental pulp soft tissue.Empty top is broad, referred to as pulp cavity, and the root canal of tubulose is arranged at lower part, by export
The blood vessel of dental nerve and trophic nerve.The mankind are general, and every tooth has 1-4 root canal, and the tooth root canal at rear portion is most.Dental pulp hair
Raw infection, will cause pain, jawbone infection, and final tooth becomes fragile because of the death of dental nerve.
Root canal preparation machine is mainly used for the root canal preparation formative stage of clinical oral.In the process, the equipment of hand-held is all
There is motor switch setting.More rearward, each use requires to carry out switch behaviour after sliding backward again the position of switch setting now
Make, is easy to generate maloperation in the process, increases patient suffering, increase work difficulty.
Summary of the invention
The purpose of the present invention is to provide a kind of lever switch to extend handle, mentioned above in the background art to solve
Problem.
To achieve the above object, the invention provides the following technical scheme:
A kind of lever switch extension handle, including extend lever, described one end for extending lever is fixedly connected with clamping
Elastic u-shaped buckle at root canal preparation machine switch, the lower surface close to the extension lever of elastic u-shaped buckle are fixedly connected with out
Close touch-control protrusion.
As further scheme of the invention: forming raised edge on the downside of the inner wall of the elastic u-shaped buckle.
As further scheme of the invention: the elastic u-shaped buckle has towards the direction for the other end for extending lever
Have an extension edge, extension edge not with extend lever contact.
As further scheme of the invention: the upper surface of the other end for extending lever is fixedly connected flexible
Pad.
As further scheme of the invention: the upper surface of the other end for extending lever offers friction lines.
As the present invention further scheme: the elastic u-shaped buckle and switch touch-control protrusion with extend lever one
Body formed connection.
Compared with prior art, the beneficial effects of the present invention are:
1, the end that pressing extends lever can make switch touch-control protrusion press root canal preparation machine switch, control root
It manages pre- standby host to switch on-off, therefore the original root canal preparation machine position of the switch can be extended to usually be accustomed to through the invention
The position used, the hand-held root canal preparation machine that user can be stable always gently start to refer to that can control root canal preparation machine opens
It closes；
2, by lever principle, torque becomes larger after extension, is less than to the power that stress point at pre- standby host switch applies and directly presses
Under power at pre- standby host switch, make equipment operator more labor-saving；
3, elastic u-shaped buckle can be quickly stuck at root canal preparation machine switch, be mounted and dismounted more convenient.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram that a kind of lever switch extends handle；
Fig. 2 is the right view that lever switch described in Fig. 1 extends handle；
Fig. 3 is the installation schematic front view that lever switch described in Fig. 1 extends handle.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Fig. 1 and 2, a kind of lever switch extension handle are please referred to, including extends lever 1, the one end for extending lever 1 is fixed
It is connected with the elastic u-shaped buckle 2 being connected at root canal preparation machine switch, close to the following table of the extension lever 1 of elastic u-shaped buckle 2
Face is fixedly connected with switch touch-control protrusion 3, and elastic u-shaped buckle 2 and switch touch-control protrusion 3, which are integrally formed with extension lever 1, to be connected
It connects；
Referring to Fig. 3, elastic u-shaped buckle 2 is stuck at root canal preparation machine switch, it is pre- that switch touch-control protrusion 3 is located at root canal
The surface of standby host switch, the end that pressing extends lever 1 can make to switch touch-control protrusion 3 pairs of root canal preparation machines switch carry out by
Pressure, control root canal preparation machine switches on-off, therefore can extend the original root canal preparation machine position of the switch through the invention
To position usually accustomed to using, the hand-held root canal preparation machine that user can be stable always, which gently starts to refer to, can control root canal
Pre- standby host switch；By lever principle, torque becomes larger after extension, is less than to the power that stress point at pre- standby host switch applies and directly presses
Under power at pre- standby host switch, make equipment operator more labor-saving；Elastic u-shaped buckle 2 can quickly be stuck in root canal preparation machine and open
At pass, mount and dismount more convenient.
Raised edge 4 is formed on the downside of the inner wall of elastic u-shaped buckle 2；The surface of raised edge 4 and root canal preparation machine is clamped
It is stronger, improve clamping ability of the invention.
Elastic u-shaped buckle 2 towards extend levers 1 the other end direction have extension edge 5, extension edge 5 not with extend thick stick
Bar 1 contacts；Increased extension edge 5 can be improved the elastic grip force of the clamping of elastic u-shaped buckle 2, further increase of the invention
Clamping ability.
The upper surface for extending the other end of lever 1 is fixedly connected with elastic cushion；Improve comfort when user's pressing.
The upper surface for extending the other end of lever 1 offers friction lines, avoids extending when lever 1 presses user and beat
It is sliding.
