The structures such as mounting groove 222 can be arranged in the outside of lock arm 22, realize the fixation to elastomer 23.
Wherein, elastomer 23 can take the shape of the letter U, as shown in Figure of description 7 comprising two adjutages 231 are located at two institutes
It states the top of adjutage 231 and the tightening portion 232 that extends towards relative direction and is located at two adjutages, 231 bottom and by two institutes
State the connected connection bottom 233 of adjutage 231；The connection bottom 233 has tightening force, to realize two adjutages 231
Pretightning force is kept with the two tightening portions 232；
The structure of mounting groove 222 is as shown in Figure of description 4 comprising：
It is respectively arranged on the outside of two lock arms 22, accommodating the pockets of two adjutages 231 respectively
2221；
It is connected to two pockets 2221, to the buckle 2222 of the fixation connection bottom 233；
Set on any pockets 2221, limiting the positive stop end of each 232 displacement of tightening portion respectively
2223；Any positive stop end 2223 includes circumferential end faces 22231 and radial end face 22232, to limit each institute respectively
State the circumferentially displaced and radial displacement in tightening portion 232.
There is accommodation space 29, to realize the opening and receipts of lock arm 22 between adjacent fixed arm 21 and lock arm 22
Tightly；Two fixed arms 21 positioned at 20 outside of washer matrix play positioning action；At the same time, two lock arms 22 all have biography
Power hole 220, force transmission hole 220 can be through-hole or counterbore etc..
On above-mentioned basis, the root of two fixed arms 21 and two lock arms 22 is equipped with axially extending bore 201,
With to avoid 20 stress concentration of washer matrix；And the axially extending bore 201 is located at the deformation hole 28 far from the card slot
26 side, as shown in Figure of description 5.
As shown in Figure of description 8 to attached drawing 17, place tool 3 includes two folding arms 31, and two folding arms 31 can
Realize open and close movement；Each folding arm 31 all has a force-transmitting pole 32, and each force-transmitting pole 32 can be with a force transmission hole
220 slotting scarves close, and after two, which open and close arm 31, opens, two lock arms 22 can overcome the pretightning force of elastomer 23 to open, from
And loosen the clamping to medical instruments such as electrodes 200.
Two folding arms 31 extend along axis, and with along the gap that axis extends 310, the gap is by two folding arms
The inner edge of 31 opposite side is formed, and the middle part formation short slot 311 of both sides inner edge namely both sides inner edge are raised outward.
Place tool 3 further includes switch upper cover 33 and folding control portion 34, switchs upper cover 33 and folding control portion 34 is removable
Connection is unloaded, can be moved synchronously along gap 310 after the two connection；Wherein, folding control portion 34 includes two receiving walls 341,
The bottom of two receiving walls 341 connects lower cover 342, and lower cover 342 and two receiving walls 341 form concave structure, two folding arms
31 part is received wherein.It switchs upper cover 33 or 34 alternatively of folding control portion is equipped with folding island 343, specification is attached
Fig. 8 shows that folding control portion 34 is equipped with the situation on folding island 343 with attached drawing 9, and Figure of description 12 shows switch upper cover 33
Situation equipped with folding island 343 opens and closes the overall structure on island 343 as shown in Figure of description 15.
In order to realize the connection of switch upper cover 33 and folding control portion 34, the attached body 12 of reference explanation book is it is found that switch upper cover
33 can be equipped with the first connecting pin 330, and two receiving walls 341 in folding control portion 34 can be equipped with second connection end 340, and first
Connecting pin 330 may be used the mode for being mutually clamped or fastening with second connection end 340 and realize that switch upper cover 33 and folding are controlled
The connection in portion 34 processed.
No matter it is equipped with which component folding island 343 is set to, extends along axis, and front end has plush copper 3431, rear end tool
There is contracting tail 3432, as shown in Figure of description 16；Plush copper 3431 can be housed inside between short slot 311, and contracting tail 3432 can be by
It is contained in gap 310；In use, two force-transmitting poles 32 are inserted in a force transmission hole 220 respectively, switch upper cover
33, folding control portion 34 is moved synchronously with folding island 343, when three synchronizes towards front end (towards the direction of force-transmitting pole 32) movement
When, plush copper 3431 is located at short slot 311 with gap 310 with contracting tail 3432, and two folding arms 31 keep initial position, at this time
Preset spacing is kept between two folding arms 31, and between the spacing and two force transmission holes 220 between two force-transmitting poles 32
Spacing is identical (in the case where elastomer 23 is not affected by external force)；When three is mobile towards rear end (direction of principle force-transmitting pole 32)
When, plush copper 3431 is detached from short slot 311, is located in gap 310 so that and gap 310 becomes larger namely two folding arms 31 open,
The spacing between two force-transmitting poles 32 becomes larger at this time, and two force transmission holes 220 overcome the pretightning force of elastomer 23 and spacing becomes larger, from
And the gap 26 between two lock arms 22 becomes larger, the medical instruments such as electrode 200 are loosened in realization, such as Figure of description 13
Shown in attached drawing 14.
Place tool 3 further includes the handle 35 extended along axis, and two folding arms 31 are fixed on handle 35, two folding arms
Elastic portion 36 is equipped between 31, elastic portion 36 can be linear spring, and one end of elastic portion 36 is butted on handle 35, the other end
It is butted on the rear end on folding island 343, as shown in Figure of description 8 and attached drawing 9；The upper surface of handle 35 is additionally provided with to be switched to fixed
The holding section 351 of 33 position of upper cover；In use, when switch upper cover 33 is moved towards rear end, elastic portion 36 is compressed,
And switch upper cover 33 can be connected in holding section 351, two folding arms 31 open, namely plush copper 3431 is detached from short slot at this time
311, it is located in gap 310, and gap 310 becomes larger, two force transmission holes 220 overcome the pretightning force of elastomer 23 and spacing becomes larger,
To which the gap 26 between two lock arms 22 become larger, the medical instruments such as electrode 200 are loosened in realization.When holding section 351
It is separated from when shutting lid 33, elastic portion 36 stretches, and pushes folding control portion 34 and switch upper cover 33 to initial position, at this time plush copper
3431 are located at short slot 311 with gap 310 with contracting tail 3432, and two folding arms 31 keep initial position, open for two at this time
Preset spacing is kept between conjunction arm 31.
