Abstract

The utility model relates to a bolt fastening spanner. The bolt fastening spanner is characterized by comprising a handle and a torsion bar connected with the handle, wherein the other end of the torsion bar is provided with a spanner head which forms certain bending angle with the torsion bar, and a bolt sleeve port matched with a pre-screwing bolt is arranged on the spanner head. The bolt fastening spanner can fasten bolts in bogging holes and with little surrounding space, and also can be widely applied in fastening various bolts.

Description

A kind of bolted spanner
Technical field
The utility model relates to a kind of spanner, particularly about a kind of bolted spanner.
Background technology
In prior art, the spanner that fastening bolt is used is commonly flat, and this spanner can only be to exposed bolt, or uses in the bigger place of spanner revolution space.Can't be fastening for the bolt that is sunken in the hole and surrounding space is less.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind ofly can carry out fastening track wrench to the bolt that is sunken in the hole and surrounding space is less.
For achieving the above object, the utility model is taked following scheme: a kind of bolted spanner, it comprises one handle and the torque arm that is connected with handle, the other end of described torque arm has the driving end that becomes certain bent angle with described torque arm, the bolt running-on that has on the described driving end Yu tight a bolt and be complementary in advance.
Described handle is vertical the connection with described torque arm.Have connecting hole on the described handle, described torque arm end has the Connection Block that is complementary with described connecting hole.
The bent angle angle of described driving end and described torque arm is not more than 90 °.
Bolt running-on on the described driving end is the plum blossom cellular type of open type or sealing.
The utility model is owing to take above scheme, and it has the following advantages: 1, the utility model comprises a torque arm and curves the certain angle driving end with torque arm, especially under 90 ° the situation, can be used to tighten the bolt that is provided with the torque arm axially parallel.2, the utility model is because driving end and torque arm curve certain angle, and spanner only is the radius rotation with the elbow part in plane, bolt place during use, and rotation takes up room less.3, the torque arm outer end connects one handle, can pass through handle rotary torsion bar, and the revolution space of handle is unrestricted.4, torque arm is connected with handle is vertical, and handle can obtain than high pulling torque.In sum, the utility model can be applied to sinking in the hole and bolt that surrounding space is less fastening.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
Shown in Fig. 1~3c, the utility model comprises one handle 1, and an end of handle 1 offers a connecting hole 2.The utility model also comprises a torque arm 3, and torque arm 3 goes out an elbow by a straight-bar bending at one end and forms.Connect a Connection Block 4 that is complementary with connecting hole 2 shapes in the straight end of torque arm 3, Connection Block 4 can be fixed in the connecting hole 2, realize being connected of torque arm 3 and handle 1.Torque arm 3 is with after handle 1 is connected, 1 one-tenth plumbness of torque arm 3 and handle.At the elbow ends of torque arm 3, connect a driving end 5, driving end 5 is straight fixedlying connected with the elbow part of torque arm 3.
As Fig. 3 C and shown in Figure 4, driving end 5 Lower Halves have the bolt running-on, the bolt running-on be an open type or sealing the plum blossom cellular type all can, so-called open type has the gap of bolt head shape exactly; So-called plum blossom cellular type is exactly the hole that the center has the bolt head, which kind of form no matter, and purpose all is wanting fastening bolt to snap into wherein, conveniently to twist.
In most cases, for structure firm solid and easy to make, torque arm 3, Connection Block 4 and driving end 5 normally are made of one, just produce the Connection Block that is complementary with connecting hole 2 shapes at an end of a straight-bar, the other end at straight-bar curves the elbow with certain angle, sets out a bolt running-on in the bottom of elbow.
In the foregoing description, connecting hole 2 promptly can be a square opening, also can be screwed hole, and Connection Block 4 matches.
In the foregoing description, torque arm 3 is 0~90 ° with the bending angle that driving end 5 forms, preferably 90 °, and the embodiment that is 90 ° shown in Figure 1.
As shown in Figure 5, when the utility model uses, select suitable driving end 5 according to the size of the bolt of tightening in advance 6 earlier.After driving end 5 blocks bolt 6, the Connection Block 4 of handle 1 with torque arm 3 ends connected, handle 1 angle of living in is selected in the locus during according to work, tights a bolt by pulling handle then.
