The distance between 1.1 inner end of spring hole zooms in or out, and resetting spring 4 compresses, is unfolded therewith, and the elastic force of generation pushes sliding block 1 multiple
Position.
First annular raised 5 are provided on guide rod 3, the part that guide rod 3 is located at first annular raised 5 side is to be oriented to
Portion 3.1, the part for being located at first annular raised 5 other side are fixed part 3.2.
Fixed part 3.2 such as is connected through a screw thread or is interference fitted at the connection types, is installed to the mounting hole of the setting of fixed seat 2.1
In 2.2, to which guide rod 3 is fixed in fixed seat 2.1.
Fixed part 3.2 is entirely enclosed in mounting hole 2.2, and first annular raised 5 stick on the surface of fixed seat 2.1.The
The surface of one annular protrusion, 5 side is bonded completely with the surface of fixed seat 2.1, and first annular raised 5 pairs of guide rods 3.1 is made to carry out
Support, avoids the deflection radially of guide rod 3.1.First annular raised 5 centralizing function also is played to guide rod 3.1 simultaneously, made
Guide rod 3.1 is vertical with 2.1 surface of fixed seat, improves the verticality of guide rod 3.1, makes the mobile side of guide rod 3 and sliding block 1
To parallel, avoid sliding block 2 in radially a degree of displacement of guide rod 3, to prevent the reset bullet moved with sliding block 1
Spring 4 and 3 joint of guide rod, cause to wear, or even resetting spring 4 is stuck.
Spring eye 1.1 is divided into the first spring eye 1.1a and second spring hole 1.1b in an axial direction.
The length of second back-moving spring 4.2 is more than the length of (the first back-moving spring 4.1, i.e. resetting spring is that elastic shape occurs
When change, the natural length of second back-moving spring 4.2 is more than the natural length of (the first back-moving spring 4.1, to make the second reset bullet
The spring travel of spring 4.2 is more than the spring travel of (the first back-moving spring.
The outer diameter of (the first back-moving spring 4.1 be more than second back-moving spring 4.2 outer diameter, and in the first spring eye 1.1a
Diameter matches, and the line footpath of (the first back-moving spring 4.1 is more than the line footpath of second back-moving spring 4.2, to make (the first back-moving spring 4.1
The elastic force being capable of providing is more than second back-moving spring 4.2.

The deformation degree of spring 4.2 is defined, and further avoids second back-moving spring deformation transition, irreversible to prevent from causing
Deformation, ensure service life.
Sliding block 1 on inclined wedge 2 when reciprocatingly sliding, work of the guide sleeve 6 in (the first back-moving spring 4.1 and second back-moving spring 4.2
Under, slide axially in the first spring eye 1.1a.
Second annular protrusion 8 and the first spring eye 1.1a clearance fits, enable shiftings of the first spring eye 1.1a to guide sleeve 6
Dynamic to be oriented to, improve the precision that guide sleeve 6 moves prevents guide sleeve to avoid radially being subjected to displacement in 6 moving process of guide sleeve
(the first back-moving spring 4.1 is guided into deflection, prevents (the first back-moving spring 4.1 from contacting the first spring eye 1.1a inner walls, causes to wear.
In order to further be fixed to (the first back-moving spring 4.1, the surface of fixed seat 2.1 is provided with fixing groove
2.3, the internal diameter of fixing groove 2.3 is identical as the internal diameter of the first spring eye 1.1a, and with the outer diameter phase of the (the first back-moving spring 4.1
Cooperation, first annular raised 5 are located in fixing groove 2.3.
Annular space between first annular raised 5 and fixing groove 2.3, limits the end of (the first back-moving spring 4.1, keeps away
Exempt from the end of (the first back-moving spring 4.1 play radially, prevent 4.1 deflection of (the first back-moving spring, ensures (the first back-moving spring
The stability of 4.1 operations.
