Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig.1, the utility model includes a kind of operation tip torque spanner, including sleeve 1, spanner 2, shaft 3, elasticity
Part (not shown) and rear cover 6, spanner 2 pass through the movable front end for being articulated in sleeve 1 of shaft 3, are provided on spanner 2 for being clamped
The card slot 221 of operation tip, rear cover 6 are connected to the rear end of sleeve 1, and elastic component (not shown) is set in sleeve 1, and one end abuts
On rear cover 6, the other end is connected to the rear end of spanner 2, and indwelling has activity space 121 between spanner 2 and sleeve 1.This is practical new
In type, since the elastic force of flexible part always acts on spanner 2, so make to screw up with a wrench operation tip when always exist one
The torque for preventing spanner 2 from rotating, only when screw-down torque is greater than the torque of elastic component offer, spanner 2 can just rotate.When
When observing that spanner 2 is rotated relative to sleeve 1, illustrates that the pretightning force of operation tip has reached the torque value of spanner setting, pass through
The control of dynamics can be realized in observation 2 rotation situation of spanner；And spanner 2 turns over certain angle (i.e. by supporting after activity space 121
Connect on sleeve 1) after no longer rotate, effect is no different with common wrench, increases the scope of application of spanner.Pass through such structure
Design, the screw thread that can effectively avoid on operation tip or handle is damaged in cargo handling process, to the dynamics of loading and unloading point
Realize rationally effective control.
Specifically, spanner 2 includes support portion 22 and the interconnecting piece 21 being connected on support portion, support portion 22 referring to Fig. 2
Width is greater than the width of interconnecting piece 21, and the width of interconnecting piece 21 is less than the internal diameter of sleeve 1, and support portion 22 is arranged in card slot 221
Front end, interconnecting piece 21 are set in sleeve 1 and are articulated on sleeve 1 by shaft 3.It should be understood that different in order to adapt to
Spanner position, card slot 221 also can be set in 22 two sides of support portion；Certainly, in order to match the demand that different size operation tip is applied,
Support portion 22 is designed to the structure of adjustable 221 size of card slot, also within scope of protection of the utility model.
Specifically, with continued reference to Fig. 2, the front end of sleeve 1 is provided with accommodation groove 12, the two of the opposite sleeve 1 of accommodation groove 12
Side offers first shaft hole 11, and the second axis hole 211 is offered on 2 interconnecting piece 21 of spanner, and interconnecting piece 21 is set in sleeve 1, shaft 3
First shaft hole 11 and the second axis hole 211 are sequentially passed through, spanner is articulated on sleeve 1, support portion 22 is located in accommodation groove 12.For
Increase aesthetics and surface area is reduced, 1 front end of sleeve can carry out contraction design, as shown in Figure 2.
In a specific embodiment, referring to Fig. 3,4, the width of support portion 22 is greater than the internal diameter of sleeve 1,21 bottom of interconnecting piece
It holds the length D of 22 bottom end of support portion to be greater than 21 bottom end of interconnecting piece to the length d of 12 bottom end of accommodation groove, is formed therebetween absolutely empty
Between and interconnecting piece 21 width and sleeve internal diameter between the space that is formed be activity space 121 described above, activity
The size in space 121 can realize that activity space 121 limits the activity point of view of spanner 2 by adjusting at above-mentioned two.
Specifically, elastic component 4 is spring or other devices that can provide stability force or mechanism.
Specifically, spanner further includes sliding block 5 in the utility model, sliding block 5 is set in sleeve 1, positioned at elastic component 4 and is pulled
Between first 2, the rear end of spanner 2 is connected under the active force of elastic component 4.
In order to guarantee stability that sliding block 5 slides in sleeve 1, sliding block 5 is tubular structure open at one end, elastic component 4
It is set in tubular structure.It should be understood that sliding block 5 or column construction, pref. cylindrical structure, the outer diameter of sliding block 5
Equal to the internal diameter of sleeve 1, to guarantee optimal abutting effect.
Specifically, realizing the adjustment of torque of wrenches value for the ease of adjusting the compressed state of elastic component 2, rear cover 6 is arranged outer
Internal screw thread (not shown) is arranged in the rear end of screw thread (not shown), sleeve 1, and rear cover 6 is screwed onto the rear end of sleeve 1, by adjusting rear
The depth that is spirally connected between lid 6 and sleeve 1, realizes the adjustment of torque value.It should be understood that by being set at 1 different depth of sleeve
Buckle structure is set, is connected on sleeve 1 by rear cover 6, above-mentioned function also may be implemented.
In another specific embodiment, sleeve 1 and rear cover 6 are an integral molding structure, the area of this structure and above structure
It is not only that assembling sequence, this structure only need to be front loaded from sleeve 1 by elastic component 4, sliding block 5 etc..
In the utility model, for the ease of using, the also settable corresponding construction of 1 outer wall of sleeve, such as non-slip groove, silica gel sheath
Deng.
Spanner is as follows using principle in the utility model: 2 card slot 221 of spanner being caught in operation tip spanner position, is then rotated
Spanner illustrates that the pretightning force of operation tip has reached the torsion of spanner setting when observing that spanner 2 is rotated relative to sleeve 1
Value, stops operating, that is, completes the handling of operation tip.By the design of such structure, can effectively avoid on operation tip or handle
Screw thread be damaged in cargo handling process, rationally effective control is realized to the dynamics of loading and unloading point.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims
Within the scope of.
