While or conflict during arc set.
In above-mentioned technical proposal, catch mechanism primarily to avoid de-regulation contact push plate when power on,
So catch is linked by drive rod and power switch, when power switch turns to on-position, the end of catch must position
In through hole and between rotating screw rod, multiple functions are realized in efficient quick a, operation, reduce component, reduce cost, and catch is into V
Font, catch are located at the lower section of drive rod, and the setting of gag lever post is that power switch is arbitrarily rotated in order to prevent, that is, ensures power supply
Safety connection, when that need not power on, that is, when testing position and separation point position, gag lever post is located under catch
Side, anti-stop tab rotate, that is, prevent power switch from rotating, and when needing to power on, that is, during link position, gag lever post moves
Go out the lower section of catch, power switch is arbitrarily rotated, gag lever post is arranged in installation cavity, passes through connecting shaft in the middle part of gag lever post
It is connected with cover board or mounting base, the second torsional spring is arranged at connecting shaft, is touched block driving gag lever post and is rotated along connecting shaft, so
Achieve that and be synchronized with the movement, ensure the uniformity of each position functions, i.e., each function of each position can be in place in time, carries
The fit precision and operating efficiency of high each component, bevel edge or arc side are formed by the chimb for being arranged on gag lever post side, touch block
Along the axial movement for rotating screw rod, when contact push plate is moved to link position, touch block and contradicted with bevel edge or arc side, will be spacing
Bar has the one end on bevel edge or arc side toward extrapolation, the positive stop end of gag lever post is produced the lower section of catch, when contact push plate is to experiment
Or during the movement of separation point position, there is gag lever post the one end on bevel edge or arc side to be drawn close towards block is touched, and make the positive stop end of gag lever post again
Positioned at the lower section of catch, the preferable exterior contour camber for touching block, so reduces friction, is moved easily, simple in structure, together
Step degree is high, coordinates closer.
Further as the utility model is set, and the shake-up block is made of the contact pushing block, on contact pushing block
Detent mechanism is provided with, the detent mechanism includes the spring channels being arranged on contact pushing block and is arranged in spring channels
Spring, is provided with positioning plate above contact pushing block, steel ball is provided between positioning plate and spring, is provided with positioning plate and steel
The location hole of pearl adaptation, steel ball coordinate as the movement of contact push plate forms flexible clamping with location hole.
In above-mentioned technical proposal, the setting of detent mechanism is to make the position of contact pushing block more accurate, and positioning plate is
Cover board, preferable location hole are three, respectively three corresponding separation, experiment and connection positions, when contact pushing block is moved to accordingly
Position when, steel ball aligns with location hole, and steel ball is caught in location hole and location hole and forms clamping automatically under the action of the spring matches somebody with somebody
Close, when contact pushing block moves, steel ball moves down under the extruding of positioning plate exits location hole, and under the action of the spring with
The medial surface of positioning plate abuts, and can be made a sound when also having steel ball to be caught in location hole, play the role of prompting, preferable contact pushes away
Block so conveniently abuts with make contact into cylinder, when slipping over make contact, will not produce larger resistance, avoid connecting
