Specific embodiment
A kind of tunnel duct piece installation spanner, as shown in Figure 1, including the identical first handle 1 of size and second handle 2,
One end of first handle 1 and second handle 2 is connected with each other by elastic component 3, and first handle 1 and second handle 2 deviate from elastic component 3
End be each provided with a V-type binding clip 4, the open end of two V-type binding clips 4 is oppositely arranged.
As shown in Fig. 2, elastic component 3 is U-shaped metal clips, the both ends of elastic component 3 are respectively connected with the link block of a rectangle
31, link block 31 offers the caulking groove 311 that can accommodate 2 end of first handle 1 or second handle on the end face of elastic component 3.
The end of first handle 1 and second handle 2 can be inserted into respectively into the caulking groove 311 of two link blocks 31 by staff, thus
It is connected with each other first handle 1, second handle 2 and elastic component 3, if first handle 1, second handle 2 or elastic component 3 damage
It is bad, consequently facilitating staff replaces the components of damage.
As shown in figure 3, the end of V-type binding clip 4 towards first handle 1 or second handle 2 is connected with a triangular prism shape
Inserted block 5, and first handle 1 and second handle 2 are towards offering the holding tank 11 cooperated with inserted block 5 on the end face of V-type binding clip 4.
Inserted block 5 on two V-type binding clips 4 can be inserted into respectively into the holding tank 11 on first handle 1 and second handle 2 by staff
It is interior, so that two V-type binding clips 4, first handle 1, second handle 2 and elastic component 3 be made to form a complete spanner.By inserted block
5 are set as the shape of triangular prism, so that inserted block 5 can not rotate in holding tank 11, to ensure opening for two V-type binding clips 4
Mouth end keeps being oppositely arranged, to make the more convenient end cap for clamping bolt of two V-type binding clips 4.
As shown in figure 4, in order to improve the stability that two V-type binding clips 4 and first handle 1 and second handle 2 are fixed, inserted block
5 towards the first fixing groove 51 is offered on the end face of first handle 1 or second handle 2, and being sticked in the first fixing groove 51 has and the
Mutually matched first magnet 52 of one fixing groove 51；And it is fixed with first in the holding tank 11 of first handle 1 and second handle 2
Second fixing groove 12 is respectively offered on the corresponding end face of slot 51, being sticked in the second fixing groove 12 has and 12 phase of the second fixing groove
The second magnet 13 mutually cooperated, to inhale iron by the first magnet 52 and second after inserted block 5 is inserted into holding tank 11
The mutual absorption of stone 13, to make to connect between two V-type binding clips 4 and first handle 1 and second handle 2 more firm.
When staff screws bolt using spanner, staff can grip first handle 1 and second handle 2, so
After be pressed against first handle 1 and second handle 2 mutually, and clamp two V-type binding clips 4 by the end cap of bolt, due to V-type binding clip
4 is V-shaped, so what two V-type binding clips 4 can be stable is clamped at the opposite end angle of bolt end cap, to make two V-type pincers
First 4 the end of bolt is clamped it is more stable.Then state rotation first handle 1 and second handle of the staff to hold
2, screw two V-type binding clips 4 to the end cap of bolt, so that staff operates more convenient, raising to spanner
Efficiency is screwed to bolt.
As shown in figure 5, first handle 1 is towards being hinged with a screw rod 6, screw rod 6 and first handle on the side wall of second handle 2
1 articulated shaft is perpendicular to the plane where screw rod 6 and first handle 1；Second handle 2 is towards opening up on the side wall of first handle 1
There is a waist-shaped hole 21, waist-shaped hole 21 is laid along the length direction of second handle 2 and waist-shaped hole 21 penetrates second handle 2, on
It states screw rod 6 to pass through out of waist-shaped hole 21, a nut 61 is also threaded on screw rod 6, the setting of nut 61 deviates from second handle 2
The side of first handle 1.Staff can be by screwing to nut 61, to make nut 61 to the side of the second first handle 1
To turn, pressing by nut 61 to second handle 2 keeps first handle 1 and second handle 2 close to each other, thus two V-types
Binding clip 4 is clipped on the nut of bolt, to save staff's hand to the work of first handle 1 and second handle 2 held with a firm grip
Firmly, but also two V-type binding clips 4 can be made to the stronger of the nut sandwiched of bolt.
As shown in figure 5, an Anti-slip cover 7 is respectively arranged on first handle 1 and second handle 2, to make hand to first
The gripping of handle 1 and second handle 2 is more comfortable.Screw rod 6 is set as hemispherical away from the end of first handle 1, so that screw rod 6
End it is more mellow and fuller, hand is scratched to reduce 6 end of screw rod, improves the safety that spanner uses.It is above-mentioned with
The nut 61 that screw rod 6 is threadedly engaged is set as wing nut 61 so that staff nut 61 is screwed it is more laborsaving.
As shown in figure 5, elastic component 3, which is provided with an auxiliary away from the side of first handle 1 and second handle 2, helps handle 8, assist
Handle 8 is helped to be hinged with elastic component 3.When two V-type binding clips 4 are clipped in the end cap state of bolt, staff is rotatably assisted
Handle 8 is helped, makes auxiliary that handle 8 be helped to be mutually perpendicular to the plane of first handle 1 and second handle 2 where common, then control auxiliary is helped
Handle 8 drives first handle 1 and second handle 2 to rotate, to keep two V-type binding clips 4 more laborsaving to screwing for bolt.Auxiliary is helped
It is additionally provided with anti-skid chequer 81 on handle 8, helps frictional force on handle 8 bigger so that hand be made to be held in auxiliary, so that auxiliary helps handle 8 to hold
It is more firm.
The course of work: staff makes first handle 1 and second handle 2 when holding first handle 1 and second handle 2
It mutually nestles, to drive two V-type binding clips 4 to be clipped in the end cap of bolt, to control first handle 1 and second handle 2 is right
Bolt is screwed or staff can make the turn on screw rod 6 of nut 61 by the threaded connection of nut 61 and screw rod 6,
And drive first handle 1 and second handle 2 mutually to nestle, and make in the end cap of two 4 loading bolts of V-type binding clip, to reduce
The pressure that hand is held, staff rotatably assist helping handle 8, and auxiliary is made to help handle 8 and first handle 1 and second handle 2 common
The plane at place is mutually perpendicular to, and then control auxiliary helps handle 8 that first handle 1 and second handle 2 is driven to rotate, to make two V
Type binding clip 4 is more laborsaving to screwing for bolt.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
