Specific embodiment
Make specific introduction to the present invention below in conjunction with the drawings and specific embodiments.
Referring to figs. 1 to shown in Fig. 3, the electrotrephine 100 of the present invention includes：Main body 10 and unidirectional carriage 20, wherein,
Main body 10 is the major part for realizing the function of electrotrephine 100, and it mainly includes：Shell 11, motor（It is not shown, similarly hereinafter）, pass
Motivation structure（It is not shown, similarly hereinafter）, saw blade 12（Fig. 1 do not show, can be found in Fig. 2）, control device（It is not shown, similarly hereinafter）.Motor is arranged
In the inside of shell 11, drive mechanism can drive saw blade 12 to be pivoted under the driving of motor, control device controlled motor
Operation.
Unidirectional carriage 20 includes：Sliding floor 21 and track plates 22 that composition is slidably connected, sliding floor 21 includes：
Chassis 23, spragging gear 24 and the brake assemblies 25 of the only one-directional rotation of spragging gear 24 can be made, spragging gear 24 and bottom
Plate framework 23 is constituted and rotates connection, and its pivot axis constitutes the direction A being slidably connected perpendicular to sliding floor and track plates；Track
Plate 22 is provided with the track tooth bar 211 that can be engaged with spragging gear.Preferably, the pivotal axis of spragging gear 24 also with saw blade 12
Pivotal axis B is vertical, and the pivotal axis of saw blade 12 then constitutes the direction A being slidably connected with sliding floor and track plates.
Specifically, brake assemblies 25 include：One can constitute the side being slidably connected along sliding floor 21 and the plate of track 22
The banking pin 26, one stretched to A can biasing detent pin 26 near spragging gear 24 biased element 27.
In order to realize the braking to " recoil ", banking pin 26 includes near one end of spragging gear 24：One yielding face
262a and braking surface 262b, makes a concession face 262a and inclines with braking surface 262b and intersect, and braking surface 262b is parallel to sliding floor
21 and track plates 22 constitute the direction A that is slidably connected；Spragging gear 24 includes：Gear 241 and detent bumps 242, braking
Raised 242 include：Can be with the yielding face 262a cambered surface profile 242a for contacting and the straight profiles that can be contacted with braking surface 262b
242b, cambered surface profile 242a and straight profiles 242b are respectively positioned at the both sides of detent bumps 242.
So, as shown in Figures 2 and 3, the direction for advancing to cutting in sliding floor 21（A direction arrows i.e. in figure
It is shown）During advance, the gear teeth of the gear 241 of spragging gear 24 coordinate with the bar tooth of track tooth bar 211, make spragging gear 24
To in figure clockwise（C arrows i.e. in figure）Direction rotate, now the side cambered surface profile 242a of detent bumps 242 with make a concession face
262a is contacted, to be inclined-plane for the direction flexible due to making a concession face 262a relative brakes pin 26, and due to cambered surface profile
242a itself has certain radian, so being rotated further with spragging gear 24, banking pin 26 is to away from spragging gear 24
Direction is moved, after subsequently contacting with the outer rim of detent bumps 242, when the detent bumps 242 turn over the position of correspondence banking pin 26
When, banking pin 26 resets in the presence of biased element 27, is inserted between adjacent detent bumps 242, when " recoil " occurs
When, spragging gear 24 is inverted, and now due to straight profiles 242b contacts with braking surface 262b, can not be supplied to banking pin 26
In the driving force of telescopic direction, so now banking pin 26 blocks corresponding detent bumps 242, spragging gear 24 is prevented from inverting
And then make gear pair locked, sliding floor 21 and track plates 22 are prevented from reverse slide, so as to inhibit the generation of " recoil ".
Used as a kind of preferred version, detent bumps 242 are located at gear axially upper side, and its number is two or more,
And the circumferencial direction in gear 241 is uniformly distributed.
It should be noted is that, for brake reaction time, certainly detent bumps 242 are The more the better, but
In view of the size of banking pin 26 and the structural strength of detent bumps 242, preferably, the number of detent bumps 242 is 6.
In addition, used as a kind of preferred version, banking pin 26 can adopt following way of realization：
Banking pin 26 includes：The key seat 261 fixed with sliding floor 21, the plunger 262 being slidably connected with key seat 261, pin
262 relatively close spragging gears 24 simultaneously form yielding face 262a and braking surface 262b；It is raised that key seat 261 is formed with step
261a, plunger 262 is formed with step projection 262c.Biased element 27 is helical spring, and it is sleeved on key seat 261 and plunger 262
Periphery and two ends step projection 261a, 262c for being formed respectively against them.
It should be noted that main body 10 both may be mounted to be constituted with sliding panel 22 on sliding floor 21 be slidably connected,
Can also be arranged on to be constituted with sliding floor 21 on sliding panel 22 and be slidably connected.In the present embodiment, use main body 10 and pacify
It is mounted on sliding floor 21.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for above-described embodiment, it is all to be obtained by the way of equivalent or equivalent transformation
Technical scheme, all falls within protection scope of the present invention.
