Two permanent seats are fixedly mounted on the adapter plate both sides respectively, two guide shafts are fixedly mounted on respectively in the hole of permanent seat at its two ends, first cliding seat and second cliding seat are equipped with bearing hole, with back-up ring linear bearing is enclosed within the bearing hole of first cliding seat and second cliding seat by the hole regularly, is enclosed within the linear bearing bearing fit first cliding seat and second cliding seat all can be slidably reciprocated along guide shaft;

First cliding seat is connected with adapter sleeve, adapter sleeve is connected with push rod, push rod is connected with second cliding seat, first cliding seat becomes to fuse with second cliding seat and can slidably reciprocate along guide shaft, baffle plate is fixedly mounted on one of them permanent seat, and two lead that reed is installed on the adapter plate symmetrically and " V " type of formation is led the spring district;

Servomotor is installed on the motor cabinet, and eccentric wheel is connected the output axle head of servomotor by flat key and rotates with output shaft; The second hinge hinge connects in the hole of inserting fork and swing rod in ground, limits the axial location of second hinge by the shaft block ring at two ends; Contiguous block is connected with the fork hinge by first hinge; The 3rd hinge one end and eccentric wheel are threaded togather, and oscillating bearing is connected and controls by hexagonal nut the axial location of oscillating bearing with the 3rd hinge hinge; The two ends of connecting rod are threaded with contiguous block and oscillating bearing respectively.

The top of fork is connected with two deep groove ball bearing hinges by the 4th hinge, controls the axial location of the 4th hinge by the shaft block ring at two ends, and two deep groove ball bearings can be rotated at the fork top.

After adopting said structure, servomotor swings back and forth fork by eccentric wheel, the fork top then promotes first cliding seat and second cliding seat slidably reciprocates along guide shaft together, thereby realizes the function of the second cliding seat compression spring, finally reach fast, efficiently, purpose accurately.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1 and Figure 2, two permanent seats 1 are fixedly mounted on adapter plate 2 both sides respectively by thread connecting mode, two guide shafts 6 fixedly mount in the hole of at both ends permanent seat 1 respectively by thread connecting mode, first cliding seat 3 and second cliding seat 7 are equipped with bearing hole, with back-up ring 5 linear bearing 4 is enclosed within the bearing hole of first cliding seat 3 and second cliding seat 7 by the hole regularly, is enclosed within linear bearing 4 bearing fits first cliding seat 3 and second cliding seat 7 all can be slidably reciprocated along guide shaft 6.

As Fig. 4～shown in Figure 5, first cliding seat 3 is threaded with adapter sleeve 25, and adapter sleeve 25 is threaded with push rod 26, and push rod 26 is threaded with second cliding seat 7, so first cliding seat 3 fuses and can slidably reciprocate along guide shaft 6 with 7 one-tenth of second cliding seats.Baffle plate 28 by screw retention be installed on one of them permanent seat 1, two lead that reed 28 is installed on the adapter plate 2 symmetrically by screw and " V " type of formation is led the spring district.

As Fig. 1～shown in Figure 3, servomotor 18 is installed on the motor cabinet 17 by bolt, and eccentric wheel 16 is connected the output axle head of servomotor 18 by flat key 24 and rotates with output shaft; Second hinge, 12 hinges connect in the hole of inserting fork 8 and swing rod 13 in ground, limit the axial location of second hinge 12 by the shaft block ring 20 at two ends; Same as above, contiguous block 10 is connected with fork 8 hinges by first hinge 11; The 3rd hinge 15 1 ends and eccentric wheel 16 are threaded togather, and oscillating bearing 14 is connected and controls by hexagonal nut 23 axial location of oscillating bearings 14 with the 3rd hinge 15 hinges; The two ends of connecting rod 9 are threaded with contiguous block 10 and oscillating bearing 14 respectively.
