Bolt connects the more convenient use become becomes an important topic.
The bolt type of attachment used at present is for install bolt by spanner, when frequently needing degree of tightness tight
The when of firmware, needing often to find spanner, efficiency is low and inconvenient, and by sky during spanner elasticity bolt
Between limit.
Utility model content
The purpose of this utility model is to provide one and carries back-up wrench type bolt, to realize by from strap wrenches
Manual elasticity bolt, easy to use, work efficiency is high, and can be capable of the tight bolt in smaller angle school.
This utility model is achieved through the following technical solutions:
One carries back-up wrench type bolt, including bolt head and spanner portion；Described spanner portion includes clamping
Portion and Handheld Division；Described Access Division is structure as a whole with described Handheld Division；
Described Access Division is tubular-shaped structures, and the inwall in described Access Division is provided with ring gear；
Described bolt head includes working thread portion and gear；The one end in described working thread portion and described gear
An end face be fixed as one structure；
Described gear is movable with described ring gear to be engaged.
Further, the end face that described gear is relative with described working thread portion is provided with extension；Described prolong
Extending portion is provided with internal thread hole.
Further, spring and fixing bolt are also included；Access Division and institute described in described fixing screw bolt passes
State after spring with described internal thread hole threaded engagement.
Further, the internal diameter of described Access Division differs, and is provided with the internal diameter of described ring gear part
More than described Access Division for the internal diameter through described fixing bolt part.
Further, the angle between center line and the center line of described Handheld Division of described Access Division is more than or equal to
90 degree.
The beneficial effects of the utility model are:
The application passes through bolt head and the structure in spanner portion, it is possible to by the spanner portion craft degree of tightness spiral shell carried
Bolt, and it is capable of the tight bolt in smaller angle school, the convenient installation or removal to bolt.

Detailed description of the invention
Describing the technical solution of the utility model by the following examples in detail, below example is only shown
Example, it is only capable of for explaining and illustrate the technical solution of the utility model, and is not to be construed as this reality
Restriction by new technique scheme.
This utility model provides one to carry back-up wrench type bolt, as shown in Figures 1 to 6, including bolt
Head 1 and spanner portion 2；Described spanner portion 2 includes Access Division 21 and Handheld Division 22；Described Access Division 21
It is structure as a whole with described Handheld Division 22；The center line of described Access Division 21 and the center line of described Handheld Division 22
Between angle more than or equal to 90 degree, be so easy to fasten or demounting bolt.
Described Access Division 21 is tubular-shaped structures, and the inwall in described Access Division 21 is provided with ring gear 211；
The internal diameter 212 of described Access Division differs, and is provided with the internal diameter of described ring gear part more than described card
The portion that connects is for the internal diameter through described fixing bolt part.
Described bolt head 1 includes working thread portion 11 and gear 12；The one end in described working thread portion 11
It is fixed as one structure with an end face of described gear 12；The external diameter of gear 12 is more than working thread portion
The external diameter of 11.
Described gear 12 is movable with described ring gear 211 to be engaged.
The end face that described gear 12 is relative with described working thread portion 11 is provided with extension 13；Described extension
Portion 13 is provided with internal thread hole 131, and in the present embodiment, the degree of depth of internal thread hole extends at gear.
Also include spring 4 and fixing bolt 3；Described fixing bolt 3 sequentially passes through described Access Division 21 and institute
State after spring 4 with described internal thread hole 131 threaded engagement.The top phase of one end of spring 4 and fixing bolt
Supporting, the other end offsets with extension.
This structure makes the spanner portion can moving axially along fixing bolt.When pressing lower ejector lever portion with hands, card
Connect the ring gear in portion to move axially and engage with gear, thus bolt head locks with spanner portion, passes through Handheld Division
Apply external force i.e. bolt head to be fastened or get loose.When unclamping by during to the power in spanner portion, spanner
Portion moves to the top-direction of fastening bolt under the action of the spring so that ring gear departs from gear, so
Spanner portion is in free state can turn to optional position, to prevent imprudence from changing spiral shell after encountering spanner portion
The state of bolt head.
Being illustrated in figure 6 this utility model and carry the application of back-up wrench type bolt, retainer ring herein needs
The most frequently dismantling, so using this kind to carry back-up wrench type bolt in fastener cycle, using
During only need free-hand can completing to remove and install.
The above is only the description of preferred implementation of utility model, it is noted that due to word
, and objectively there is unlimited concrete structure in the finiteness expressed, common for the art
For technical staff, on the premise of without departing from this utility model principle, it is also possible to make some improvement
And retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
