Shelve to offer to correspond in some perforation, the rotating shaft on the connection that rotates, the axle sleeve and offer some arc grooves, it is described
Perforation is provided with slip cap with being provided with to slide axially along it on ball, the axle sleeve in the arc groove, the slip cap
On offer ladder axis hole, return springs, the return springs set are provided between the slip cap and the mounting bracket
On the axle sleeve, the drive mechanism for driving the slip cap to slide is provided between the slip cap and the mounting bracket.
It is further improved to be：Be additionally provided with guiding optical axis between bearing block described in two ends, the guiding optical axis with it is described
Leading screw is parallel to be set, and the pilot hole being engaged with the guiding optical axis is offered on the travelling carriage.
It is further improved to be：The drive mechanism include be arranged on the mounting bracket guide rod, be slideably positioned in
Unlock piece on the guide rod, the unlock piece is mutually fixedly connected with the slip cap, and operation is connected with the unlock piece
Drag-line.
It is further improved to be：The motor is Worm reduction motor.
It is further improved to be：The ball has six.
By using preceding solution, the beneficial effects of the invention are as follows：Normal condition lower leading screw is driven by motor, works as electricity
, can be by operating clutch to separate motor with leading screw, so as to realize that manual actuation leading screw is rotated, no when machine breaks down
Can normally it be used due to electrical fault influence seat.

Embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As Figure 1-Figure 2, the present invention is disclosed is provided with slip on a kind of single track slide unit, including leading screw 1, the leading screw 1
There is the screw being engaged with the leading screw 1, the leading screw 1 is provided at both ends with bearing block 3, described on frame 2, the travelling carriage 2
Leading screw 1 drives rotation by motor 4, is provided with clutch between the leading screw 1 and the motor 4, the clutch includes
Mounting bracket, the axle sleeve 5 that is connected with the leading screw 1, the rotating shaft 6 being connected with the axle of motor 4 of the motor 4, the axle sleeve 5 and institute
State rotating shaft 6 and rotated with the mounting bracket and is connected, correspondence in some perforation 7, the rotating shaft 6 is offered on the axle sleeve 5 and is opened
Provided with some arc grooves 8, the perforation 7 is axially sliding along it with being provided with the arc groove 8 on ball 9, the axle sleeve 5
Dynamic be provided with slip cap 10, the slip cap 10 offers ladder axis hole, is set between the slip cap 10 and the mounting bracket
Be equipped with return springs 11, the return springs 11 are sheathed on the axle sleeve 5, the slip cap 10 and the mounting bracket it
Between be provided with the drive mechanism for driving the slip cap 10 to slide.
In the present embodiment in order that the more stable slip of travelling carriage 2, be additionally provided between bearing block 3 described in two ends and lead
To optical axis 12, the guiding optical axis 12 is parallel with the leading screw 1 to be set, and is offered and the guiding light on the travelling carriage 2
The pilot hole that axle 12 is engaged, is oriented to optical axis 12, it is engaged with the pilot hole on travelling carriage 2 so that travelling carriage 2 by setting
Sliding stability.
In order to easy to control, guide rod 13 that the drive mechanism includes being arranged on the mounting bracket, it is slideably positioned in
Unlock piece 14 on the guide rod 13, the unlock piece 14 is mutually fixedly connected with the slip cap 10, on the unlock piece 14
Operation drag-line is connected with, passes through pull operation drag-line so that unlock piece 14 drives slip cap 10 to slide, so that slip cap 10
On multi-diameter shaft hole site change, so as to realize the clutch of clutch.
Preferred technical scheme is in the present embodiment, and the motor 4 is Worm reduction motor 4.
Preferred technical scheme is in the present embodiment, and the ball 9 has six.
Operation principle：When clutch is in closed state, ball 9 is pressed in perforation by the aperture of the shoulder hole on slip cap 10
7 with arc groove 8 so that axle sleeve 5 and rotating shaft 6 are an overall structure, when motor 4 drives the rotating shaft 6 to rotate, while with moving axis
Set 5 is rotated, so as to drive leading screw 1 to rotate, when sliding the slip cap 10 so that during the macropore alignment ball 9 of shoulder hole, electricity
When machine 4 drives the rotation of rotating shaft 6, because the upper surface of ball 9 has lacked binding force, so that ball 9 with rotating shaft 6 when rotating, edge
Perforation 7 to slide, so that axle sleeve 5 will not together be rotated with rotating shaft 6, in addition by setting ball 9, when the load pressure of motor 4
When excessive, slip cap 10 overcomes the elastic force of return springs 11 to slide so that clutch is in released state, so as to
Effectively protection motor 4 will not be burned.
