Abstract

The utility model discloses a kind of hand-rail type Screw arbor with nut at both-ends fastener, comprise crank body, rotation hand that rotary type is arranged on handle place, crank body one end and at least one be fixedly mounted on the ut socket of the crank body other end; The outer wall of ut socket and the outer wall of the crank body other end fix, and the end face of the sleeve-port of ut socket and the crank body other end flushes.This hand-rail type Screw arbor with nut at both-ends fastener can carry out Quick fastening to the clamp nut on Screw arbor with nut at both-ends, and easy to use, has good market application foreground.

Description

A kind of hand-rail type Screw arbor with nut at both-ends fastener

Technical field

The utility model relates to a kind of construction tool, especially a kind of hand-rail type fastener for Screw arbor with nut at both-ends.

Background technology

At present, job site normally uses spanner to carry out fastening to the clamp nut of Screw arbor with nut at both-ends, but due to amount fastening during site operation very large, compare effort with spanner, and the spanner also inconvenience construction of some position of joints.

Utility model content

Utility model object: providing a kind of can carry out fastener quick and easy to use to Screw arbor with nut at both-ends.

Technical scheme: the utility model provides a kind of hand-rail type Screw arbor with nut at both-ends fastener, comprise crank body, rotation hand that rotary type is arranged on handle place, crank body one end and at least one be fixedly mounted on the ut socket of the crank body other end; The outer wall of ut socket and the outer wall of the crank body other end fix, and the end face of the sleeve-port of ut socket and the crank body other end flushes.

Adopt and rotate hand can convenient construction librarian use, prevent palm from rubbing injured, improve convenience and the comfortableness of use; Adopt ut socket to be set on the clamp nut of Screw arbor with nut at both-ends, then drive clamp nut sleeve to rotate together by shake crank body, compared to spanner, obviously there is fastening speed faster, and use also more convenient; Because the fastening distance of the clamp nut on Screw arbor with nut at both-ends is longer, conveniently Screw arbor with nut at both-ends passes ut socket, so ut socket must be arranged on the outer wall of the crank body other end; In order to avoid the other end of crank body rubs mutually with the propeller on Screw arbor with nut at both-ends, so the sleeve-port of ut socket must be set to flush with the end face of crank body.

As further improvement of the utility model scheme, the outer wall rotating hand handle is provided with anti-skidding flange collar.Adopt anti-skidding flange collar effectively can improve the non-skid property of rotating hand handle.

As further restriction scheme of the present utility model, ut socket is two altogether, and the sleeve-port of two ut sockets varies in size.Adopt two ut sockets varied in size, this fastener can be made to have better pervasive performance.

Compared with prior art, its beneficial effect is the utility model: (1) adopts and rotates hand can convenient construction librarian use, prevents palm from rubbing injured, improves convenience and the comfortableness of use; (2) adopt ut socket to be set on the clamp nut of Screw arbor with nut at both-ends, then drive ut socket to rotate together by shake crank body, compared to spanner, obviously there is fastening speed faster, and use also more convenient; (3) because the fastening nuts distance on Screw arbor with nut at both-ends is longer, conveniently Screw arbor with nut at both-ends passes ut socket, so ut socket must be arranged on the outer wall of the crank body other end; (4) in order to avoid the other end of crank body rubs mutually with the propeller on Screw arbor with nut at both-ends, so the sleeve-port of ut socket must be set to flush with the end face of crank body.

Detailed description of the invention

Below in conjunction with accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.

Embodiment 1:

As illustrated in fig. 1 and 2, hand-rail type Screw arbor with nut at both-ends fastener of the present utility model comprises: crank body 1, rotation hand are 2 and two ut sockets 3.

Wherein, rotate hand and 2 rotary types are arranged on handle place, crank body 1 one end; Two ut sockets 3 are fixedly mounted on crank body 1 other end; The outer wall of ut socket 3 and the outer wall of crank body 1 other end fix, and the end face of the sleeve-port of ut socket 3 and crank body 1 other end flushes; At rotation hand the outer wall of 2 being provided with anti-skidding flange collar 4; The sleeve-port of two ut sockets 3 varies in size, and needs to arrange the different ut socket 3 of multiple large ting model according to practice of construction.

As shown in Figure 3, hand-rail type Screw arbor with nut at both-ends fastener of the present utility model in use, first according to the clamp nut 6 on the Screw arbor with nut at both-ends 5 of different model size, the ut socket 3 of respective model sleeve-port is selected to be set on clamp nut 6, shake rotates hand 2 again, the other end of crank body 1 is made to drive ut socket 3 to start to rotate, the turning moment be made up of crank body 1 is enough to the fastening requirements meeting clamp nut 6, clamp nut 6 is made to promote propeller 7 fastening forward along Screw arbor with nut at both-ends 5, so use quicker and convenient than spanner, effectively can improve the fastening efficiency of construction of Screw arbor with nut at both-ends.

As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
