垫片8和中心导轨螺母9固定在中心导轨1上并随其运动，作动器出杆端和加载机构的中心导轨1的左端通过销钉固连。当作动器伸出，即向右运动时，中心导轨1的轴肩推动左弹簧座3运动，压缩弹簧4的左端，其右端被右弹簧座5限制而固定，故弹簧4被压缩而提供随位移呈线性变化的负载力；当作动器缩回，即向左运动时，相对中心导轨固定的中心导轨螺母9和垫片8推动导套6、右弹簧座5运动，压缩弹簧4的右端，其左端被左弹簧座3限制而固定，故弹簧4被压缩而提供随位移呈线性变化的负载力。这样，作动器在伸出和缩回的过程中，加载机构就能够提供双向对称的力，由此实现了本发明的技术效果。 The spacer 8 and the center rail nut 9 are fixed on the center rail 1 and move with it, and the rod end of the actuator and the left end of the center rail 1 of the loading mechanism are fixedly connected by pins. When the actuator stretches out, that is, when it moves to the right, the shoulder of the center guide rail 1 pushes the left spring seat 3 to move, compresses the left end of the spring 4, and its right end is restricted and fixed by the right spring seat 5, so the spring 4 is compressed to provide The load force varies linearly with the displacement; when the actuator retracts, that is, moves to the left, the center rail nut 9 and spacer 8 fixed relative to the center rail push the guide sleeve 6 and the right spring seat 5 to move, compressing the spring 4 The right end and the left end are limited and fixed by the left spring seat 3, so the spring 4 is compressed to provide a load force that varies linearly with the displacement. In this way, during the process of extending and retracting the actuator, the loading mechanism can provide bidirectional symmetrical force, thereby realizing the technical effect of the present invention.
