As shown in Figures 1 to 5, present disclose provides a kind of relay extracting tool, including the first clamp 1 and the second clamp
2, the first end of the first clamp 1 and the second clamp 2 can relative motion to cooperatively form jaw 3, opposite with first end second
End is movably connected.It in this way, can be by operating being realized close to or away from action to relay for the first clamp 1 and the second clamp 2
Clamping and release, wherein, jaw 3 in the disclosure includes the first groove 4 being formed on the first clamp 1 and is formed in
The second groove 5 on second clamp 2, the first groove 4 is with the second groove 5 to that can be formed to surround to cooperate to opening
The enclosed jaw of relay.When need to dismantle relay, it is closed jaw 3；During release relay, jaw 3 is opened.
In the disclosure, as a result of enclosed jaw, when gripping relay, 3 inner wall of jaw is filled with relay outer wall
Tap is touched, compared to prior art, the contact surface that both increases so that the power that jaw 3 acts on relay is distributed to relay
On device, stress concentration damages relay during so as to can effectively avoid gripping.
In the disclosure, the first groove 4 and the second groove 5 can be any proper shape, in order to existing relay
Shape preferably matches, the contact area of increase jaw 3 and relay.In one embodiment, as shown in Fig. 2, first is recessed
4 and second groove 5 of slot is formed as n connected in stars, i.e. the side wall including bottom wall and positioned at the bottom wall side, in this way, first is recessed
The cooperation of 4 and second groove 5 of slot can be formed as square shape jaw.
It is typically that multiple relays are densely arranged in a relay mounting box during relay use, Mei Geji
It is spaced between electric appliance small.Therefore dismounting working space very little, so in the disclosure, the wall thickness of jaw 3 cannot be excessive, i.e. the
The bottom wall and side wall of one groove 4 and the second groove 5 cannot be too thick, and otherwise during operation, relay extracting tool easily bumps to it
Its relay can damage other relays.Therefore it can expire in the bottom wall and side wall for ensureing the first groove 4 and the second groove 5
As far as possible wall thickness is processed thinner on the premise of sufficient intensity requirement.
In addition, in the present embodiment, and because during operation, external force is consequently exerted at the two of the first groove 4 and the second groove 5
On a bottom wall, so two bottom wall stress are compared with side wall bigger, so can set larger by the thickness of bottom wall.In this reality
It applies in mode, the sidewall thickness of the first groove 4 and the second groove 5 can be 1mm-2mm, and bottom wall thickness can be 2mm-2.5mm.
In the disclosure, as shown in Figure 4 and Figure 5, relay extracting tool is provided with close on the first clamp 1 of second end
First through hole 13, the upper surface correspondence position of the second clamp 2 are provided with threaded hole 14, and first through hole 13 has close to the second clamp
2 the first stepped hole 15, one end of the first spring 6 are pressed on the step surface of the first stepped hole 15, and the other end is pressed on second
At the threaded hole 14 of 2 upper surface of clamp, coupling bolt 7 passes through 13 and first spring 6 of first through hole and 14 thread fitting of threaded hole.
Wherein, the diameter of coupling bolt 7 is more slightly smaller than first through hole 13.In this way, when clamping relay, the first clamp
1 and second clamp 2 can be moved toward one another along coupling bolt 7 until fitting, at this point, the first spring 6 is compressed；After completing dismounting,
External force is removed, under the action of the first spring 6, the first clamp 1 and the second clamp 2 separate, and realize the release of relay.
In the disclosure, as shown in Figure 3 and Figure 4, relay extracting tool further includes pressing mechanism, by operating pressing machine
Structure may be such that jaw 3 has first position and the second position, and in first position, jaw 3 is closed to clamp relay；In second
It puts, jaw 3 is opened with release relay.It is easy to use.
In one embodiment, as shown in Figure 3 and Figure 4, pressing mechanism includes pressing piece 10 and connector 9, connector 9
Lower end be fixedly mounted on the second clamp 2, upper end is through the first clamp 1 and hinged with pressing piece 10, and pressing piece 10 is formed as
Lever construction, which has the fulcrum for supporting the first clamp 1, and one end is hinged with pressing piece 10, and the other end is formed
For press-side.Specifically, when clamping relay, the fulcrum of pressing piece 10 is supported in the upper surface of the first clamp 1, is pressed by operation
The press-side of casting die 10 makes fulcrum compress the first clamp 1 downwards, and at the same time hinged end can rotate with connector 9, and
And connector 9 transmits the force to the second clamp 2, and so that the first clamp 1 and the second clamp 2 can be bonded, 3 shape of jaw at this time
Into and be fixed as enclosed jaw, jaw 3 is tightly outer at this time is sleeved on relay, in this way, can extract relay.Lever knot
The setting of structure so that the dismounting laborsaving convenience of operation.
In the present embodiment, pressing piece 10 can have any appropriate structure and shape.In one embodiment,
As shown in Figure 3 and Figure 4, pressing piece 10, which has, is located at the first segment 11 of fulcrum both sides and second segment 12,12 company of being articulated with of second segment
Fitting 9, first segment 11 is compared with second segment 12 from fulcrum towards away from the 1 direction inflection of the first clamp.Wherein, from labour-saving, angle goes out
Hair, can suitably increase the length of first segment 11, using long arm lever structure, the dismounting for making relay is more light.
In the disclosure, as shown in Figure 3 and Figure 5, the second through hole 16 is provided on the first clamp 1 of first end, the
Two clamps, 2 correspondence position is provided with third through-hole 17, and the second through hole 16 has the second stepped hole 18 close to the second clamp 2, the
Two springs, 8 one end is pressed on the step surface of the second stepped hole 18, and the other end is pressed on the third through-hole of 2 upper surface of the second clamp
At 17.Here, the reset response to jaw 3 is played in the cooperation of 8 and first spring 6 of second spring.It, can be more preferable using double-spring structure
Ground ensures that the first end and second end of the first clamp 1 and the second clamp 2 can reset in time, in order to relay extracting tool energy
Enough in extremely rapid succession operations.
In one embodiment, as shown in Figure 3 and Figure 4, connector 9 is formed through the second through hole 16, second spring 8
With the axis pin of third through-hole 17, and axis pin is fixed in third through-hole 17.The hinge of axis pin is provided perpendicular on pressing piece 10
