Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of medical hospital bed guardrail special handling tool, including reciprocating lever
And 5 and shell interconnected 11 and lever 7；The reciprocating lever 5 successively shell 11 and lever 7 described in activity grafting；It is described past
One end of compound lever 5 connects handle 8, and other end socket spring 10 simultaneously penetrates the shell 11；The reciprocating lever 5 is equipped with spring base
51；The spring base 51 abuts the spring 10；
Push handle 8 that reciprocating lever 5 can be made to travel forward, spring 10 is shunk；Handle 8 is unclamped, spring 10 is sprung back, reciprocating lever
5 returns.To avoid return is excessive from causing to be additionally provided with bayonet lock 6 on the reciprocating lever 5 in 5 retraction shell 11 of reciprocating lever；Bayonet lock 6 can
To be located in shell 11, can also be located in the head for being pierced by shell 11.
Coaxial runner 2 and gear ring wheel 3 are equipped in the shell 11；The runner 2 and gear ring wheel 3 can be rotated independently；
The outer ring of the gear ring wheel 3 is equipped with teeth；The reciprocating lever 5 is equipped with the helical tooth 9 engaged with the teeth.Reciprocating lever 5 is done
When reciprocating motion, the drive gear ring wheel 3 of helical tooth 9 is done to be rotated forward or backwards.
The inner ring of the gear ring wheel 3 is equipped with ratchet 1；The runner 2 is equipped with pawl 4 corresponding with the ratchet 1.Back and forth
When bar 5 advances, gear ring wheel 3 is rotated forward, and ratchet 1 pushes pawl 4 and then runner 2 is driven to rotate together；To make gear ring wheel 3 drive runner
When 2 rotation, uniform force.The quantity of the pawl 4 of the utility model is two, and the two is in 180 ° of angles.Certainly, pawl
4 quantity may be three or four, and 4 uniform ring of each pawl is located at the periphery of the runner 2；Pawl 4 is equal when rotation
Divide stress, prolongs the service life.
When reciprocating lever 5 retreats, gear ring wheel 3 is inverted, and is skidded when ratchet 1 rotates with pawl 4, therefore runner 2 does not rotate.This reality
Torsional spring is used to connect between the novel pawl 4 and runner 2；To automatically reset when the skidding of pawl 4.
The runner 2 is also fixedly attached rotation axis 22；The rotation axis 22 penetrates the shell 11, and being in shell 11 can
Rotation socket；The both ends of the rotation axis 22 are respectively equipped with slot 21.Slot 21 can be with the sleeve or screw head of grafting different size.
By taking nut as an example, the corresponding sleeve of 21 grafting of slot simultaneously covers connected nut, then pushes handle 8, dismantles nut.It needs
When tightening nut, sleeve is plugged into the slot 21 of the other end, repetitive operation can tighten nut.And so on use this reality
Bolt or the screw etc. of dimension can also be unclamped or tightened with the screw head of novel plugging different size.Rotation axis 22 can be done
Elongated, the nut of small space convenient for loading and unloading.
It referring to fig. 2, is the independent rotation for realizing gear ring wheel 3, as a kind of embodiment, the gear ring wheel of the utility model
Sandwiched thrust bearing 31 between 3 and shell 11；Bearing holder (housing, cover) 32 is equipped on the side of the gear ring wheel 3 and the inner wall of shell 11；
