Further, the lower end of the pedestal is provided with the second guide and limit screw, and the lower end of the sliding block is provided with second
Chute, one end of the second guide and limit screw are inserted in second chute, the external diameter of the second guide and limit screw
It is engaged with the width of second chute, for the guiding of the sliding block and spacing, using reliable.
Further, the upper end of the push rod is provided with arc chord angle, reduces contact area, avoids interference with.
The beneficial effects of the invention are as follows：(1) cylinder is set, the mode that original screw rod promotes is changed, improves certainly
Dynamicization degree and production efficiency, reduce labor intensity；(2) first inclined-plane, the second inclined-plane are set, by the anti-of the push rod
Force decomposition, auto-lock function is realized, it is reliable；(3) guide and limit screw and chute are set, it is ensured that the push rod and
The sliding block is moved with fixed track all the time at work, improves stability and reliability；(4) structural principle is simple, throws
It is low to enter cost, it is easy to use.
