one end of the screw rod 21 passes through the limiting hole 121 to be in threaded connection with the threaded hole 221, and the other end is hinged with the hinge bracket 23.

Specifically, on the one hand, through threaded connection of screw rod 21 and slider 22, when rotatory screw rod 21, slider 22 butt is unable to move at limiting plate 12, only make screw rod 21 rotation and along support 1 length direction rectilinear movement, namely reach the function of adjusting support 1 length, satisfy required different length under different scenes, can promote the practicality of whole support 1, on the other hand, when facing the earthquake, slider 22 is in the slip between the support 1 inner wall, make the power conversion of vibrations for frictional force, frictional force reconverts for the heat, the substantial effect of self-shock attenuation has been reached.

It should be noted that when the device is used, the two sliding blocks 22 are firstly ensured to respectively prop against the limiting plates 12 at the two ends of the bracket 1, and then the optimal length of the whole device is adjusted by twisting the screw 21.

The connection between the sliding block 22 and the screw 21 is a thread, but not a polished rod, so that vibration received by the screw 21 can be transferred to the sliding block 22, when the screw 21 rotates, the sliding block 22 is abutted to the limiting plate 12, the screw 21 rotates and moves linearly to adjust the length of the whole device, when vibration in different directions is received, the screw 21 transfers the received vibration to the sliding block 22 in threaded connection, and the spring 24 buffers the impulsive force of the sliding block 22, so that the sliding block 22 rubs back and forth on the inner wall of the bracket 1 to generate heat.

In this embodiment, further, an observation port 13 is provided on one side of the bracket 1, where the accommodating chamber 11 communicates with the outside. Specifically, because the welding of limiting plate 12 is sealed afterwards for slider 22 can't drop out, in holding chamber 11 back and forth sliding, when screw rod 21 and slider 22 are connected, not only selective torsion, still a thrust along support 1 length direction, under the effort of spring 24, the staff can go again to guarantee that slider 22 supports limiting plate 12 motionless by hand, rotatory screw rod 21 can impel screw rod 21 again, otherwise slider 22 can move along with the connection of screw rod 21, influence the connection of screw rod 21 and slider 22, consequently design viewing aperture 13, the installation of staff can be convenient for also reach simultaneously and observe inside condition, the inside purpose of clearance of being convenient for.

In this embodiment, further, the bracket 1 is provided with a abutment 14 for abutment of the slider 22 and the spring 24 on the side of the viewing opening 13. Specifically, after the slider 22 receives the force of vibrations, the friction mode on the line is preferentially considered to cancel the force of vibrations, if the existence of the threshold 14 is not resisted, the slider 22 and the spring 24 which are subjected to the vibration force in different directions are easy to fall off from the observation port 13, so that potential safety hazards are caused, in order to avoid the occurrence of the above situations, the threshold 14 is added to resist the slider 22 and not fall off the accommodating cavity 11, and meanwhile, the slider 22 can be touched through the observation port 13, so that the interior of the accommodating cavity 11 is cleaned.

In this embodiment, further, the friction plate 222 is also fixedly connected to the inner wall of the bracket 1. Specifically, in order to increase the efficiency of converting the vibration force into the friction force, the friction plate 222 is added on the surface of the inner wall where the bracket 1 contacts with the sliding block 22, the friction plate 222 is fixedly connected with the sliding block 22, when the bracket 1 is vibrated, the friction plates 222 on two sides generate heat by mutual friction, so that the heat dissipation is accelerated, the damage to the connected objects is minimized, and the service life of the friction plate 222 needs to be prolonged, and the staff needs to maintain after reaching a certain degree.

In this embodiment, further, the limiting plates 12 are welded to two ends of the bracket 1. Specifically, the manner of welding the limiting plate 12 and the port of the bracket 1 is firmer than other manners, the cost is lower, the manner is simpler and more concise, and further, other threads or clamping can be adopted, but only the weight is smaller, and the requirement for stability is met for the depth of the threads and the manner of clamping, otherwise, the potential safety hazard caused by falling is great.

In this embodiment, further, the thickness of the limiting plate 12 is greater than the thickness of the bracket 1. Specifically, the position with the greatest stress of the whole device is the force of the sliding block 22 abutting against the limiting plate 12, and the two screws 21 stretch the sliding block 22 to the opposite direction at the same time to tightly abut against the limiting plate 12, so that the supporting effect of the device is realized, if the limiting plate 12 is not present, the two screws 21 and the bracket 1 cannot be combined into one, so that the requirement on the limiting plate 12 is higher, thinner materials are not easy to use, and the thickening is needed to offset the tensile force transmitted to the sliding block 22 by the screws 21.
